Opening speech

In order to implement the spirit and related requirements of the important speech made by the Supreme Leader General Secretary at the symposium of scientists, and vigorously promote the spirit of scientists, China Optics has opened a column of Interview with Academician since the first issue in 2021.

This column will combine interviews, self-reports and other diversified forms to record the unforgettable stories of academicians in their growth, teaching, scientific research and other experiences, as well as their understanding and thinking on life, science, education and other issues, so as to show the patriotic dedication and innovative and realistic spirit of the older generation of scientists.

Interview with Academician was carefully planned and organized by Chen Xingdan, an academician of China Academy of Sciences and a famous optical expert in China. Although Mr. Chen is over 80 years old, he personally invited academicians, called relevant editors to compile and sort out the final draft word by word. Mr. Chen’s hard work is the quality assurance of this column, which is deeply admired and respected by our colleagues.

The column "Interview with Academician" will continue to be carried out, and I sincerely hope that readers can get to know them and understand them through this column, so as to enlighten and gain something.

I spent my childhood in war.

My father, Li Lurong, was born in Nanhai, Guangdong, and worked as a clerk in the administrative organs. Later, he joined relatives as a clerk in Shanghai. My grandfather was a former Qing Dynasty juren with a rich family. My mother, Zhang Ruiwen, inherited her grandfather’s wisdom. She went to school and worked as a primary school teacher. She is thoughtful and opinionated. When her father is away for many years, the whole family is fully supported by her mother.

In 1936, I was born in my grandmother’s home-Dongguan County. I was the first child in my family, and soon I had a second one-my younger brother. I spent my childhood in war. I went to the third grade in Dongguan Yuanyong Primary School and moved to Guangzhou with my family to continue my primary school and junior high school. By the second day of junior high school, I was admitted to Guangya Middle School, which is a school that children from poor families hope to enter. From the second day of junior high school, I entered this boarding school until I graduated from high school, and experienced the liberation of Guangzhou (1950). After liberation, due to the financial difficulties of my family, I insisted on studying with the support of national grants.

Second, unforgettable and elegant

Guangya Middle School, formerly known as Guangya Academy, was founded in 1888 by Zhang Zhidong, Governor of Guangdong and Guangxi Provinces. Its name is taken from "Broad people are great" and "elegant people are just", which means to cultivate knowledgeable and upright people. In Guangya Middle School, I learned to live independently, manage myself, develop freely and happily, and cultivate my good self-study habit and self-improvement spirit.

I am most interested in physics class.

I am curious by nature and like to explore the unknown. In Guangya Middle School, the course I am most interested in is physics. Mr. Wu Weitang, a physics teacher, gave a logical and fascinating lecture, which showed us a brand-new world. It is a great pleasure for me to borrow extracurricular books, especially reference books on physics. As a result, after a period of time, I couldn’t find any physics extracurricular books that I could continue to borrow in the middle school library. Reading extracurricular books makes me learn actively and deeply.

My diary recorded an impressive physics class. In that class, Mr. Wu asked questions for everyone to answer. "Now ask the fourth question, please answer it. What is the internal current of the battery? Ask Li Yanda to talk about it. " I have thought about this question for a while, and briefly organized what I want to say a few seconds before I stood up. I replied: "Charged ions are attracted by the electric field caused by the two poles and move regularly. Negative ions move to the positive electrode and positive ions move to the negative electrode to form the current in the battery." Teacher Wu kept nodding his head in agreement: "What he said is completely right, and his answer is very good and perfect. Let me ask another question, how to expand the meaning of the current in the conductor and combine the composition of the current inside the battery to summarize the meaning of the current? " Looking forward to everyone. I have been thinking about it for a long time, and finally I think that both electrons and ions are tiny particles with mass, which can be represented by particles. At this time, the teacher’s eyes looked at me and said, "Can you ask Li Yanda to answer this question again?" I stood up and answered briefly, "charged particles are attracted by the electric field and move regularly to form an electric current." Teacher Wu immediately nodded and said, "The answer is absolutely right and can be summarized. Have you thought that electrons are particles like ions? This answer is very good, very rare. Li Yanda must have read a lot of reference books beforehand, and he has a thorough understanding of this question. In the two years since I taught physics in senior high school, no one has given such a complete and comprehensive answer, which is rare. You all study hard at physics,But the power of generalization is not enough, so we should learn from Li Yanda, who summed it up very well. You should know that his answer this time is absolutely right. "Such a compliment is extremely rare for Mr. Wu. Extra-curricular books are really helpful to me. I have read some questions about solution current in extra-curricular books, and I have thought that ions may move. In physics class, the teacher mentioned that "in metal, current only moves electrons, and ions are stationary, but this is not the case in other objects." These words may sound like nothing to other students, but they touched my thoughts and confirmed my understanding. I answered the questions and answers in this class by combining reading extra-curricular books with my experience in class, because these questions would not be talked about in high school physics class at that time.

The habit of reading extracurricular books has benefited me a lot.

I read a wide range of extracurricular books, not only in physics. For example, I have read "A Brief History of Lenin’s Life and Career" and "Marina’s Life Path" and made notes. I wrote in my diary: "This book is so good that it gives me great enlightenment. I like reading books very much at this time. People simply can’t lack books. I especially like reading books about the growth of heroes, typical books about lofty morality, and I like those heroes. A person’s beauty lies not only in his appearance, but also in his heart and whether his character is noble or not. Marina’s goodness lies in her constant upward trend, loyal personality and brave and determined spirit. "

Every time I read a good book, I discuss the topic of life with my partners. Good books are so important to me that I sighed in my diary: "I can’t live without books for a day. The library is the most fascinating place. This feeling has been deeply felt as early as my freshman year." I love what Marx said: I would like to be a bookworm.

From now on, loving reading and reading all kinds of books has become my lifelong hobby, which has also helped me form a self-learning ability. In the first year of high school, I was hospitalized for nearly a month because of illness, and all the courses I missed were made up by myself. Especially when I was studying geometry, I read a book "One Hundred Ways to Solve Geometry Problems" in the hospital, and I actually kept up with the progress. I always feel that I don’t have enough time because I am interested in reading books. Although I also made a reading plan, I never finished it. In addition, as a monitor, I am busy with many things. Gradually, I am used to arranging my time effectively. I often pay attention to the main points and improve efficiency when doing things and reading books. This method is very effective when used in course study. After a class, I can often sort it out with a page, and it is easy to review. Therefore, even during reviewing for exams, I still find time to read extra-curricular books. This habit benefited me a lot in my later study and work.

Third, study in Tsinghua

In college, I have developed a unique set of skills of listening to lectures and reviewing.

After graduating from high school, I was admitted to the Department of Electrical Engineering in Tsinghua University.

I didn’t know Tsinghua University at first, and my first impressions were two: First, Tsinghua is a good place for diligent study, especially the library in Tsinghua University, which greatly meets my demand for books; Second, Tsinghua University’s teachers are very good, such as Mr. Zhong Shimo, Mr. Zhao Fangxiong, Mr. Tong Shibai, etc. They not only speak well in class, but also have outstanding personality charm.

In this demanding environment of Tsinghua University, I have not only laid a solid foundation in basic knowledge, but also developed my thinking method and learning method. Because of the great freedom and difficulty of studying in college, I have developed a unique set of skills of listening to lectures and reviewing in order to adapt to the tense college life. Because I am good at grasping the main points, once I grasp the main points in class, it is easy to understand; In the classroom, I often feel that there are many tedious and repetitive contents in what the teacher says. Just staring at the teacher will lead to low learning efficiency. It is better to use the time between lectures to compare the teacher’s methods with your own ideas and list your own doubts. In order to grasp the main points of classroom knowledge more quickly, I often take time to read more books and do some preview when reviewing. Five minutes before class, I will recall the preview content and get a general impression of the central content of this class. In this way, I think while listening, analyze while listening, and write down the main points and similarities and differences, which greatly improves the efficiency of listening to lectures. Over time, the classroom is no longer a place to memorize knowledge, but a place for me to do analysis and comparison. Therefore, I can often put forward some of my own views, and I can also integrate the knowledge of extracurricular books into the course content. Throughout one’s life, knowledge is accumulated slowly, and only the knowledge that one is very interested in and carefully thought about will be accumulated in one’s mind. It is not difficult to do this, as long as you have the heart and form a habit, the result will be inevitable.

Dialectics has opened a new window for me

My study habit of reading extracurricular books became an active part in extracurricular activities when I was in college. I remember when I was a sophomore, I took part in extracurricular scientific and technological activities about the essence of electromagnetic field. This is a study of the nature of matter. In some people’s view, the appearance of electromagnetic field makes matter "disappear". In order to discuss this problem, I especially studied dialectics of nature. I like reading Laozi’s Tao Te Ching very much. The dialectical thinking method has opened a new window for me. Without dialectical thinking, it is not only difficult for a person to enter the room in science, but also difficult to suffer setbacks in life. The dialectical thought makes me understand the dialectical relationship between success and failure, and between rise and fall, so that I can face failure calmly and attach importance to learning from it. When it goes well and rises, I often realize the crisis and make arrangements for the next leap. I can often analyze and observe a problem from the big picture and the whole, and look at new technologies and potentials from the perspective of development and change. All these have played an unimaginable role in my future work. Consciously combining dialectics with research work is also one of my most important gains in college.

After graduating from college, I spent seven years in scientific research, groping in practice, learning by doing, and learning what I can’t learn in books. Pay attention to the questions raised by practice, the research results should be applied to practice, understand the gap between book knowledge and practice, etc. These understandings and experiences were learned during this period, and I gradually matured in this way. Exploring the unknown and curiosity is my lifelong interest and pursuit, and it is also an endless driving force for forming a way of thinking.

3 broaden your horizons, climb high and look far.

With the increase of knowledge and the gradual expansion of the fields involved, my knowledge is also growing. I found that many things have similar properties and different fields have internal relations, and my horizons are gradually broadened, and my understanding and understanding of subject boundaries and subject development are also suddenly enlightened, and I gradually have my own insights.

I studied automatic control in college, and engaged in electronics and digital control for more than ten years after graduation. In 1959, I took part in the maintenance and operation of the first machine tool program control computer in China. Although a group of young people in Tsinghua knew little about program-controlled computers at that time, a group of young people who dared to think and do it could design and manufacture program-controlled computers by themselves after a year or two of hard work. This has greatly inspired me to further emancipate my mind and dare to think and do it. Then I led the graduate students to develop the first program-controlled computer of drilling machine in China and put it into production.

Four, MIT for two years.

In 1978, I passed the exam and became the first group of visiting scholars to the United States, and had the opportunity to study at the Massachusetts Institute of Technology (MIT). For some other reasons, my research direction shifted from electronics to signal processing. Although I have only been at MIT for two years, I have gained a lot. The most important thing is to broaden my horizons, and at the same time, I have entered a new research field and found a new direction.

In January 1979, Deng Xiaoping (second row, fifth from the left) cordially received the first batch of Chinese students studying in the United States in the new era at the China Embassy in the United States. The third row from the left is Academician Li Yanda.

I used to major in electronic circuits, and I worked under Mr. Tong Shibai. Before going abroad, Mr. Tong arranged for me to learn microprocessor, and asked me to open this course when I came back. At that time, going abroad required two people to write letters of recommendation. I found Mr. Chang Yong, who is a master of MIT and a doctor of Harvard. Mr. Chang asked me to learn signal processing and bring back the class. So it is written on the application form: the first volunteer microprocessor, the second volunteer signal processing.

The tutor I originally chose when I went to MIT was Professor Fan Li, who was the director of the MIT microprocessor laboratory. However, it was the first time that New China sent visiting scholars to the United States, and several institutions did not make it clear that they would accept these people, including MIT. It is said that when MIT professors discussed whether to accept these visiting scholars, Mr. Lin Jiaqiao urged them to accept them. However, some Jewish professors who are very influential in MIT raised some difficult questions. For example, they suggested that the basic condition for visiting scholars is to have a doctorate, and none of these Chinese have a doctorate, so they can only come to MIT as students, not as visiting scholars. As a student, you have to pay tuition, which is actually not accepted. Mr. Lin Jiaqiao argued that there was no doctor’s degree in China, and emphasized that the level of these people met the requirements. The two sides were at loggerheads, and finally a Jewish professor named Oppenheimer proposed a compromise: let them come in first and see before deciding. Finally, MIT professors decided to conduct an investigation for one year. If these people are qualified, they will be treated as visiting scholars, and if they are not qualified, they will be treated as students and receive tuition fees. Because it was Professor Oppenheimer who put forward this suggestion, he would set an example to receive a Chinese and then report the assessment results to other professors a year later. He is an expert in signal processing. After reading the application materials of all visiting scholars, he found that only I chose signal processing. Although it was his second choice, he chose me. So when I came to MIT, I was assigned to Professor Oppenheimer.

I was 42 years old that year, the same year as Professor Oppenheimer. The first time we met, I told him: We graduated from university in the same year, but I just went through the Cultural Revolution for ten years, and you studied for a doctor and opened up your own research direction, so the two of us have been separated for more than ten years. At that time, my first task was to learn the course well, and I could continue to offer this course when I returned to China.

It is not easy to study in Professor Oppenheimer’s laboratory. I have never seen the computer system in the laboratory and I don’t know how to operate it. Once I was studying the instruction set and tried the functions of each instruction one by one. The last instruction was: Shut down. As soon as I executed it, I shut down the computer system of the whole laboratory. At that time, the whole laboratory was in an uproar, and some people had opinions and opinions about Chinese. But then one thing changed my situation.

Although I switched to signal processing from Professor Oppenheimer, I still have the task of learning microprocessor. During the summer vacation, Professor Fan Li’s laboratory provided an Intensive Course on microprocessors. For one and a half months, more than 30 senior engineers attended classes. The process of learning this course was very tight and the homework was very heavy. At that time, my English was not good and I didn’t understand it very well. The final exam is to give each of these more than 30 people a chip, and ask everyone to build a circuit by themselves. If they can read the information in the chip and display it, they will pass. I am very familiar with the circuit. I was the first to make it in two or three days and passed the exam, which surprised some people. The tutor of this course is a graduate student, who is in close contact with Professor Oppenheimer’s laboratory, and the news spread. Since then, the attitude of people in Oppenheimer’s group towards me has changed greatly.

After spending half a year in Oppenheimer’s group, I taught myself two or three courses, such as Signal Processing, by reading books and watching videos. Feeling that I should do scientific research, I went to Professor Oppenheimer and said that I would take part in the scientific research work in the group. Professor Oppenheimer was very surprised. He always thought that I would only take courses, so he asked me which research group I wanted to go to. I chose seismic exploration. Professor Oppenheimer said that he would have a look at it first, and gave me a topic, asking me to find information to do the calculation myself. A week later, I handed in the results, and he gave me another doctoral thesis for me to read. After more than a month, I understood the paper and put forward my own suggestions for improvement, which made me enter his research group. Professor Oppenheimer is an expert on how to apply phase spectrum. At that time, I realized that phase spectrum is closely related to wave delay, and the information of stratum structure can be obtained by using wave delay. My work has also given Professor Oppenheimer a new experience. It turns out that the phase function he proposed can also be used in the study of wave delay and geological structure. Professor Oppenheimer recognized my work, and our group of people also performed well in their respective fields. Therefore, we were all treated as visiting scholars without paying tuition fees, and later MIT accepted new visiting scholars.

Before going abroad, I was mainly teaching in Tsinghua, and my research was mainly tracking and imitating. Only at MIT did I understand how to do scientific research-make new things! During the two years at MIT, my research shifted from electronic circuit to signal processing, which opened up a new research direction and also learned to consider problems from a higher level. Whether it is electronic circuit, signal processing or feedback control, it is actually a problem of information transmission and processing. From a higher level, they are interlinked. I later studied the Internet from the perspective of information control to solve the congestion problem. The essence of bioinformatics is to study the inheritance of DNA information, and information inheritance determines material inheritance. The essence of life is also an information process. All my later work was carried out along such a line.

MIT’s two-year visit has greatly broadened my horizons, made me see the rapid development of foreign science and technology and our backwardness, and strengthened my confidence in emancipating my mind and daring to think and do. However, the most important harvest is: I stand at a different height and have the feeling of climbing high and looking far.

Five, after returning to China to explore a new way of seismic exploration data processing technology.

After returning to China, I devoted myself to using new signal processing methods to find oil and natural gas for the country, that is, data processing for oil and gas exploration. It is very complicated and difficult to process a large number of oil and gas exploration data by computer to find oil layers buried thousands of meters underground. There are several ways to find oil and gas now, mainly by the so-called "seismic exploration" method. Geologists usually analyze the conditions of oil generation and accumulation in areas based on geological surveys, and then generate seismic waves through artificial explosions in areas where oil generation and storage are possible. The seismic wave propagates downward to several thousand meters of oil layer and then reflects to the ground, and the reflected wave can be received by installing a geophone on the ground, and then the cross section of the underground structure can be obtained by computer processing. Geological engineers analyze these structures, find structures that can store oil according to experience or known knowledge, and finally confirm them by drilling wells. However, in the early stage of exploration, the success rate of well drilling is often very low. Our task is to assist geological engineers to better judge oil layers and improve the hit rate of well drilling. Processing exploration data by computer developed greatly in 1960s and 1970s, and achieved great success. By the 1980 s, this method had become more and more complicated, and the results achieved were getting smaller and smaller.

After a period of research, although we made great efforts, the results were not very satisfactory, and I began to rethink the route of our work. My thinking is not limited to the specific topic at present, but the whole exploration method. I think the well location determined by seismic exploration often fails to produce oil. What is the fundamental reason? My conclusion is that the main reason is not that the computer processing is not fine enough, but that the data obtained by seismic exploration is not enough to determine the location of underground oil layers. From the point of view of information theory, it is a problem of insufficient information. For this problem, no matter how to study the computer processing method, it can’t be solved. The basic way to solve this problem is to increase the amount of information, that is to say, to supplement new knowledge about underground oil layers from other aspects. The more such knowledge is supplemented, the more effective it is to solve the problem. When I look around the whole process of exploration, I find that there are several important ways to understand the underground oil layer: one is that drilling wells and logging provide local detailed information of the underground; The other is the inference and analysis of underground oil layers by geological engineers according to geological conditions. Then, isn’t it just to solve the problem of insufficient information by incorporating logging data and information provided by geological engineers’ experience into seismic exploration data? However, because geology, logging and seismic exploration technology are all very complex disciplines or technologies, and they are self-contained, usually an engineer only knows one of them, and the separation of disciplines has caused the separation of the three to a certain extent. Secondly,There are also great differences among them in technology. The knowledge of geological engineers is vague and it is difficult to describe them accurately and quantitatively. The resolution of logging data is very high, but it is only a "one-hole view" with a narrow spatial scope; Seismic data has a wide range in space, but its resolution is low in local depth. More importantly, the amount of seismic data is huge, which needs to be processed by a large computer. The processing process is complex and it is difficult for manual intervention. It is very difficult to combine other data on a large computer. Therefore, when I realized that if we can combine the knowledge of logging and geological engineers with seismic data, it is possible to achieve new results, I began to consider how to realize this scheme. However, when I asked some experts to integrate the three, most of them shook their heads and said it was difficult. It is not easy to realize the integration of the three under the environment and limitation of large computers.

In the mid-1980s, when Professor Chang Yong came back from a visit abroad, he told me excitedly that a new type of computer-workstation appeared abroad. Its performance is equivalent to that of medium-sized and large-sized computers, but it is small in size and easy for manual operation and human-computer interaction. I immediately realized that a rare opportunity came-it must be possible to realize the combination of the three on the workstation. I have a premonition that the traditional seismic exploration data processing technology is coming to an end, and it is necessary to make bold decisions and embark on a new road. This is the combination of the above three. This analysis has strengthened my determination to overcome all difficulties and embark on a new path. After several years of hard work, my graduate students and I have opened up a new road, and initially realized the combination of the three, and the effect is obvious. Three new high-yield wells have been drilled in Shengli Oilfield by this new method. At the same time, the international community is developing in this direction. At present, it has become a common working mode and an important means of oil and gas exploration to process seismic exploration, geological engineer interpretation and logging data at the same time on the workstation, and to interact or combine them with each other.

Six, some experiences of scientific research work

1 don’t do what others have done.

When I was doing research work at MIT, I had the opportunity to get in touch with Professor Lin Jiaqiao, a famous scholar. He is a scholar I admire very much and his contribution to mathematics is universally recognized. I asked him what he should pay attention to in learning and what suggestions he had for my future research. He told me, "Don’t do what others have done." This sentence is very enlightening to me. I understand what he said, but it doesn’t mean that you shouldn’t do what others have done. If you want to learn and understand a lot of work, you must repeat what others have done. It goes without saying that a lot of development and production work is done on the basis of others’ work. I think the original intention of his words is: the research topic and research goal you have determined should be unprecedented and truly exploratory and pioneering. If we only repeat and make some repairs on the basis of what others have done, it is of little significance in research and will only waste a lot of energy, which should not be valued by a scientific researcher.

At the beginning of my scientific research work, I only took part in existing projects or worked with teachers, but I didn’t seriously consider this problem. When I came back from the United States in the early 1980s, my horizons and the height of seeing problems were different. Professor Lin Jiaqiao’s instruction can be said to hit the nail on the head, which has raised my research work to a new level. It is from the basic point that "no one has done it" that I set my research objectives and methods. Compared with the past, they all went all out, but the results were very different, which really benefited a lot.

Grasp the key and go all out.

I also adopt the methods used in my study when dealing with research work. When the research topic is determined, I am used to grasping the main points and key points, simplifying the problem into one or two key problems, and then going all out to concentrate on solving it. Because the problem is concentrated into one or two key problems, all your energy can be focused on one or two points, forming great penetration like an awl. For example, when I was studying signal processing methods at MIT, my professor was a famous scholar in the field of signal processing, and his research work reached the most advanced level in the world at that time. As my foundation is weak, he hopes that I can take more courses and learn more about the work done by his doctoral students. But I think "nothing ventured, nothing gained". I should not only learn advanced theories and existing achievements, but also be able to apply and even develop them and create something. This is my goal. According to my analysis, the instructor has made new innovations in signal reconstruction, and the most important point is to reconstruct the signal by using the phase function. I will seize this point and study it in depth; On the other hand, I choose oil and gas exploration data processing as an application field, and a key problem to be solved in this application field is the delay of finding the arrival time of signals. I vaguely feel that there is some connection between the two. After repeated thinking, I find that the arrival time of the signal is determined by the phase function, so the phase function can be used to determine the delay time in essence. I was very excited to find this internal relationship, and then I repeatedly thought about how to express the relationship between the two in mathematics, starting with the establishment of the model.To write general expressions. After continuous thinking, I finally found a new method and a new expression to estimate the delay problem by reconstructing the signal with phase function, and proved the feasibility of this new method with simulation data. This achievement made the guidance professor very happy, and personally took me to the relevant research center to report this achievement and write it into his summary report. Later, this achievement was also published in internationally renowned journals. Grasping the key and going all out, this method not only benefits me greatly in my study, but also is the most important weapon in my research work.

Put forward new goals in time, not afraid of failure.

A discipline has its process of occurrence, development and decline, and a person engaged in research in a certain field has to go through a similar process. When a person reaches the peak of his success, it also means that he may go downhill. At this time, he should be alert, have a sense of crisis, and set new goals for himself in time. In addition, I think, if you want to explore, don’t be afraid of failure. My first success is often based on dozens of failures. I am not afraid to admit defeat. When I put forward some new ideas, I am often ridiculed, opposed and sometimes even sharply criticized by some people. I don’t care about any of this, I just laugh it off. I think this is one of my great advantages.

Why am I always exploring? I think on the one hand, it is out of curiosity, and on the other hand, I see greater opportunities. Since I returned to China in 1981, I have been mainly engaged in seismic exploration data processing for more than ten years. My team has made some achievements after many twists and turns in its research work since childhood. Since 1993, when my research achievements were rewarded and I was undertaking larger projects, I felt that my work in this field for more than ten years had developed from the beginning to a peak and was going downhill. I have a sense of crisis, and I think it’s time to set new goals for myself. My feeling tells me that network information is a rapidly developing new field with a lot of opportunities. Therefore, I set out to set up a network information research group to apply the intelligent information processing methods we have studied for many years to network control and network information retrieval. Although we are beginners in network information, we have accumulated many years of knowledge in intelligent information processing and intelligent control. The establishment of this research group has given us new goals and inspired our new research ideas. With the development of the Internet in the world and the information superhighway in China, our new network information research group has also developed rapidly, attracting a group of promising young people, and our research has also achieved rapid results and published papers in important publications at home and abroad. Since 1996, with the implementation of the human genome project, a large number of genetic information and data have emerged, which urgently need further analysis by information scientists.The research of bioinformatics will be an important topic in the 21st century, and our other bioinformatics research group is also working closely with biologists to conduct new research.

In my opinion, the interdisciplinary and interdisciplinary edge is exactly where we can make great achievements. In the information age, we should not be complacent and arrogant, but be very sensitive, pay great attention to the development of world science and technology, make full use of the information obtained from all over the world through communication and opening up, and keep up with the times.

4. Establish an ideal, scientific and democratic team.

Nowadays, scientific research is always a collective behavior. The combination of experience and insight, acumen and diligence can often be more fully reflected in a group. A promising scholar should also be an organized person. Because I often serve as a monitor and a league branch cadre in middle schools and universities, I have cultivated my ability of unity and organization, and accumulated experience in social work for my future study and work. Teacher Chang Yong placed great expectations on building an ideal, scientific and democratic team, and also did a lot of work, which also had a great impact on me. We bring the spirit of daring to challenge the world-class level to the research group, set high standards, encourage exploration, allow failure, promote democracy and discuss on an equal footing in the research group, and gradually form an atmosphere. Through the efforts of the whole group, we have established a common goal and established national self-confidence and pride. Here, as an organizer, it is most important to have ideals and beliefs, perseverance and disregard for personal gains and losses. Fortunately, I often work in such a group, which is often the source of my innovative ideas and inspiration, and the most sensitive part of my vision and touch. It is great fun to do research and exploration in such a young group.

5 About basic research

A problem that has been puzzling China’s scientific and technological circles is that science and technology and economy are two skins, and the two cannot be well combined. Over the years, we have always emphasized that "tasks should bring disciplines" and "science and technology should serve the economy", and we have taken many measures, but there are not many original achievements in innovation, and there are still "two skins" in the combination of science and technology and economy. If we have found the problem and attached great importance to it, it has not changed obviously for a long time, then it is likely that we have a problem in the guiding ideology of solving the problem.

When the Second World War came to an end in 1944, people were thinking about how to change science and technology from serving war to serving social development in peacetime. At that time, President Roosevelt gave this task to Dr. Bush, director of the American Scientific Research and Development Agency. After in-depth study, Dr. Bush and a group of outstanding experts put forward a report-"Science-endless frontier". This report has a great influence on the scientific research and economic development of the United States in the following decades. During this period, American science and technology have been at the forefront of the world, and the American economy has been constantly innovating and developing rapidly with the support of science and technology. When our country begins to get rid of the strong external pressure and various wars and carry out reform and opening up in a relatively peaceful environment, it is worth studying the experience provided by this report.

The main focus of this report is on the importance of basic research, which points out that basic research will lead to new knowledge. It provides scientific capital, and it creates such a reserve from which the practical application of knowledge must be extracted. New products and new technological processes are not completely mature as soon as they appear. They are based on new principles and new concepts, which are painstakingly developed in the research work in the purest field of science. Today, basic research has become the leader of technological progress, which is more clear than ever. A country that relies on other countries for new basic scientific knowledge will have a slow industrial development and a weak position in world trade competition, no matter how sophisticated its mechanical skills are. The report requires that the government’s funds for basic research must maintain a steady increase trend. Dr. Bush also pointed out that basic research should be given special protection and special guaranteed support. In 1968, when the US Congress authorized the National Science Foundation to support applied research in addition to basic research, Bush’s Committee on Science and Public Welfare warned that there is a tenacious law governing scientific research: under the pressure of demanding immediate results, applied research will inevitably exclude pure scientific research unless well-thought-out policies are formulated to prevent this from happening. The lesson is clear: it is pure scientific research that deserves and needs special protection and special guaranteed support.

The report also pays special attention to personnel training. In the part of "Renewing our scientific talents", President conant is quoted as saying: "-In every aspect of the whole field that can be properly called" science ",the limiting factor is people. The speed of our progress in a certain direction depends on the number of truly first-rate talents engaged in the said work. So in the final analysis, our basic education policy will determine the future of this country. "

As for strengthening industrial research, the report points out that "the simplest and most effective way for the government to strengthen industrial research is to support basic research and develop scientific talents". The report points out that "one of the most important factors affecting a large number of industrial research is the tax law", and the report suggests that the domestic tax law should be revised to eliminate the uncertainty of deduction of research and development funds.

I think it is clear that we can learn something from this report. The frontier of science and its potential benefits are still endless.

Seven, about personnel training

1 Character, knowledge and talent

Talent cultivation and postgraduate education have always been my thoughts. What do students want to learn in school? I once said the following words to the first-year graduate students of automation department:

Comrade Gao Shiqi, an old senior in Tsinghua, wrote the following words when he returned to Tsinghua in his later years:

"tsinghua campus studied for eight years, and welcomed the new year after 60 years of hard work.　

Today’s dedication stems from yesterday’s learning.

The achievements of old people come from little diligence. "　

It seems that only by being good at learning can you be a good graduate student, and only by being good at learning can you constantly strive for self-improvement and progress.

What should I learn during my graduate studies? I think we should learn "character, knowledge and talent" in reading and research.

Among them, the most difficult and useful thing to learn is character, followed by knowledge and talent. In fact, Tsinghua’s greatest influence on people is Tsinghua people’s character. During the summer vacation, many visitors to Tsinghua asked me where the moonlight was on the lotus pond in Tsinghua. Moonlight in the lotus pond shows Tsinghua people’s elegant sentiment, while Mr. Wen Yiduo’s angry behavior shows Tsinghua people’s integrity and backbone. What impressed our generation the most was Mr. Wang Ganchang. When the organization wanted him to participate in the development of an atomic bomb to counter the nuclear threat of the United States, Wang Ganchang’s answer was: "I would like to make my country." This reflects Tsinghua people’s life goals and traditions. Sentiment, righteousness and ideals of life have influenced generations. If you don’t improve your character, you have never read. This is just as the great scholar Cheng Hao said: "Today people can’t read. If you read the Analects of Confucius, you are such people when you don’t read it, but only such people after you read it, that is, you have never read it. " I hope we can improve our character by reading.

Secondly, what I want to say is to improve my knowledge. This includes knowledge and knowledge. In my opinion, knowledge is easy to learn, but knowledge is hard to find. There are different realms of knowledge.

Mr. Yu Youren wrote two poems:

"Let the cranes fly for thousands of hectares, and fish for a bay."

These are two kinds of realms, a crane soaring into the sky, and the eyes are all over the world. And fishing is just in the river bend. Only with such vision can we have such knowledge. Generally speaking, as Professor Huang Ziqing said, science can only ask "How", not "why". The students joked that science can only say "good" but not "bad". But I think science should be able to ask both "How" and "Why".

But if you ask "Why", it is often a bigger question. Its thinking needs vision, knowledge and imagination, and there is often no answer. Because if you ask "Why", you may ask "Tao". I have a saying, "Tao can be Tao, but it is extraordinary." On a smaller scale, if you take problems that others don’t know or can’t solve as your research direction, you need knowledge and imagination.

If reading and research can not only learn knowledge from teachers and classmates, but also increase "knowledge", it will be "trip worthwhile".

The third is talent, that is, the ability to solve practical problems. Be able to communicate with others, be eloquent, be reasonable, respect others, be good at uniting people and so on. Some people do everything smoothly, and some people can’t do anything. This is the performance of ability.

Some people say that as a graduate student, a good paper is everything. However, how do good papers come out? If you really do research, you are actually exploring in unknown areas. The process is like groping for the exit of a house in the dark. You often hit the wall everywhere, but the door may be at your hand, and you just pass by. At that time, you may be very upset or even very disappointed, so I suggest you, if you are strong enough, stick to it. Or, you may think it’s an act of god, go back to the dormitory and sleep. It’s also feasible to change the house and look for it next week. But never fake or copy. According to my experience, 80% of the time, "God" will give you an exit.

Because most of our research can only be regarded as "fishing in a stream", rather than traveling around the world like a crane, it is not difficult to find an exit. However, character, knowledge and talent are not given by "God". Only these three things are the true meaning of being a successful person and the ability to help you find an exit forever. I hope everyone will pay attention.

2 Postgraduate education should really face the future

Why is it that China has always imitated and tracked more, repeated scientific research at a low level, created less independently, developed new frontier disciplines slowly, and had few top-notch talents at a high level, especially those who led the development of a discipline? In my opinion, in addition to being limited by China’s economic development level and insufficient investment, graduate education should also bear part of the responsibility.

Talents in new frontier disciplines should be trained among graduate students, not just those in existing disciplines. Graduate students will be brought to undergraduate education when they are mature, thus promoting the renewal of undergraduate courses.

It is a well-known problem that the subject content of undergraduate education in China is slowly updated and the content is aging. The root cause is that graduate students have not made great efforts to cultivate new talents in frontier disciplines. With the development of new subject areas, new subject leaders will naturally appear, which is handsome. We are top-notch in the field of science and technology, and there are few talented people who have a great influence in one field, which is also related to the inability to sensitively cultivate talents in new disciplines in the future in graduate education.

Everyone knows that there will be a large number of breakthrough topics from interdisciplinary subjects, but in the past, we often lamented the difficulty in the development of interdisciplinary subjects and attributed it to the imperfect management system. In fact, fundamentally speaking, the guiding ideology of postgraduate education does not really face the future. This can be said to be an important issue that affects the quality of postgraduate training and the training of real talents. This is not a question of specific management methods, but a question of ideas. Without advanced ideas, there will naturally be no new talent training mode, which is worthy of our in-depth consideration.

Take bioinformatics as an example to make a concrete analysis. Since the implementation of the Human Genome Project in the 1990s, biology, especially molecular biology, is undergoing a major change, from the biology that only focused on one gene or one protein in the past to the new system biology. By identifying tens of thousands of genes and millions of single nucleic acid polymorphisms, genomics will help reveal the root of the problem and find the best treatment for many genetic diseases. The wave of "genomics" such as genomics, transcriptomics, metabonomics and proteomics is promoting this change. This is a great opportunity to give birth to new frontier disciplines and grow new academic leaders. However, many graduate students in this field can’t adapt to this change. Where is the problem? Professor David R. Brown (Professor of Pharmacology, Neuroscience and Toxicology) of the University of Minnesota in the United States thinks that "part of it is an education problem" because we are training pharmaceutical workers who are aware of the progress of genomics and proteomics? Are we training molecular biologists who will participate in the process of drug discovery? Neither. In this new discipline, molecular biologists and drug workers should not only become information scientists, but also the information among genomics, proteomics, physiology, medicine and biochemistry must be mutually convertible, which is the significance of the discipline of "bioinformatics or In Silico".

People of insight, advanced universities and professors in the United States, Britain and Japan quickly seized this field and trained talents in this new discipline with new teaching contents. The new graduate team also vigorously promoted the development of this field. It has become the consensus of some first-class universities that professors should train a group of new people according to the requirements of the frontier of science and the needs of the future, and corresponding management methods have been developed for many years.

If we just think that this is an interdisciplinary problem, I think it is not enough. Education should really carry out the idea that education should face modernization and the future.

Today, with the rapid development of science and technology, the development of science and technology provides a great opportunity for China’s economic development, and also provides a great opportunity for China’s science and technology to catch up. But why is it that China’s innovation ability has been difficult to improve compared with the world, and it has long lacked real talents and masters? I’m afraid it’s not that our intelligence in Chinese is insufficient. I think part of the problem lies in education, especially postgraduate education.

Tsinghua University celebrated Teachers’ Day in 2015.

Viii. Bioinformatics-Opening up New Fields

Around 1996-1997, the human genome project was in full swing, and a large number of genome data emerged. Being very sensitive to "data", I naturally wouldn’t miss such an opportunity.

The diagnosis and treatment of diseases is moving from reductionism to system theory.

Our diagnosis and treatment of diseases is moving from reductionism to system theory. At present, most of the research on life science still stays in local details. In the future, the study of life science should rise to a holistic and systematic height, because life is a whole. We need to combine micro and macro! The Human Genome Project has brought our analysis of the human body system into the gene level and an unprecedented field. In order to understand the occurrence of diseases, we are eager to understand the function of genes and protein. However, with the exception of a few genes and protein, most genes and protein do not work alone. Most genes and protein often interact with each other, and their relationship is like a very complex network.

We are faced with the following problems: searching for genetic variation that leads to genetic diseases in complex biomolecular networks, searching for drug targets for treating diseases or symptoms from gene protein networks, and then searching for cancer markers.

How to analyze this network? We can’t break up the network and analyze it in multiple parts, but we must analyze it as a whole; However, usually we only know a small part of this complex network. How can we analyze the role of genes or protein from a part of the network? This problem has been bothering us for nearly ten years!

2 Correlation analysis-relationship inference is a breakthrough.

Correlation analysis is a breakthrough! The early breakthrough of this problem lies in finding mutant genes of non-familial genetic diseases. For familial genetic diseases, we can find the corresponding family and find its special gene mutation through linkage analysis; However, for non-familial genetic diseases, traditional methods are no longer applicable. In desperation, people have come up with correlation analysis: simultaneous occurrence is correlation.

Divide patients and healthy people into two groups, and find gene mutations that appear in patients but not in healthy people. These gene mutations are "related" to genetic diseases. Of course, it is not enough to find the related gene mutation, but also to confirm the truly disease-related gene mutation through prior knowledge, mechanism analysis, experimental verification and other methods, preferably through independent verification by a third party. Finally, this method was proved to be feasible, and with the continuous expansion of the experimental population, it was extended to the whole genome analysis and achieved remarkable results.

We further expand the correlation analysis into relationship inference and propose the CIPHER algorithm. We assume that phenotypes are more similar and related genes are closer, that is, "the distribution of phenotypic similarity" is consistent with "the distribution of gene proximity". Given a phenotype, we can find the corresponding genes. The key of this method is to combine the macro and micro, and to connect the characterization with biomolecules. By using the phenotypic correlation, we can find gene mutations with similar phenotypes from known phenotypes, and we can find drug targets for diseases. By using the "relationship inference" method, we have succeeded in some applications.

The change of diagnosis and treatment of diseases from reductionism to system theory is a major development of medical undertakings, which is of great significance to early diagnosis of diseases, precise medical care and drug research and development. Substantial progress has been made in this regard.

2010 Xining-Lhasa Bioinformatics Symposium

3 big data is more about big data.

Relationship inference enables us to understand the meaning of big data more deeply-to provide all aspects of "relationships", which plays a key role in solving complex system problems!

There are a lot of omics data in molecular biology, and there are also a lot of data on diseases and medicine, which is a veritable big data; However, when we search cancer data, we find that the sample size is very small, because even if they are both liver cancers, there are many subtypes, because there are many possible combinations of mutations, and they are closely related, but they are not samples of the same class; What big data gets is actually a high-dimensional small sample, which is "relationship" big data! It is precisely because of the "relationship" provided by big data that relationship inference is of great use. Vigorously developing relationship inference is very important for the prediction and intervention of biological system, social system, social system, financial system, economic system and military system.

Today, science and technology have experienced Newton’s mechanics, Einstein’s theory of relativity and quantum mechanics. It seems that they have developed very richly and profoundly, and mathematics has developed perfectly, with more and more branches of science becoming more and more specialized. When science seems to be omnipotent, when people really face the complex world, they suddenly find that all science and technology are so limited and simple; When people explain the world with the perfect law, they find that they often run into a wall, and the contingency of world development is so great! What the hell is going on here? Now, even the basic problems, people are shaking their faith in the past "truth". For example, how did the universe come into being? Did organisms evolve according to Darwin’s theory of evolution and the principle of survival of the fittest? What is the secret of life? And so on, this is really a wonderful era. In my opinion, the boundaries of various disciplines are becoming more and more blurred, and interdisciplinary subjects have become the fastest-growing disciplines. With the development of computers, the realization of the human genome project, the emergence of global networks and the high-speed exchange of information, the science and technology of human society are developing at an unprecedented speed, and we are facing a new era of science. Random and nonlinear new analytical methods are making great and even fundamental changes in the analytical methods and conclusions of various disciplines in the past. This is a golden age that provides great opportunities for people engaged in scientific exploration! We are living in such a lucky era. In this era, we dare to imagine and be good at cross-research.It is very important to dare to grasp things in essence and in general. Only in this way can we seize the opportunity of this era to the maximum extent and be worthy of this era. I hope such talents will appear more in the East and in China.

1905 movie network news The official announcement of the film starring in,,, and starring in, has been raised to June 12, 2021 for the national public release, opening the summer season ahead of schedule with the trend of heat waves. At the same time, the film also exposed the "Hidden Witness" version of the character poster. The promotional word "6.12 is first to dry" to fill the heat value. The poster style conveys a retro summer atmosphere. All the main characters appear and go to a summer night mystery.

　

"Once Upon a Time in the Tropics" "Versailles" lineup debuted, Peng Yuyan, Zhang Aijia and Wang Yanhui joined hands to "peek at the truth"

After the movie "Once Upon a Time in the Tropics" released the "High Temperature Warning" set poster and the "Exposing the True Killer" set trailer at the beginning of summer, the film became the top choice for audiences to watch in June, saying: "After waiting for a few years, it’s finally here"; "This lineup is too advanced"; "The trailer is so hot, the summer file is locked". Recently, "Once Upon a Time in the Tropics" has revealed the character poster again, and the official announcement has been raised for a week. It will be released nationwide on June 12, 2021. Not only will it officially enter the Dragon Boat Festival file, but it will also start the heat of the summer file in advance. The character poster released by "Once Upon a Time in the Tropics" this time, the starring actors will appear as "secret witnesses" for the first time.

Peng Yuyan’s Wang Xueming wears a dark blue hoodie with a gloomy expression that seems to have a heavy heart; Zhang Aijia’s Liang Ma has curled hair and a wistful expression, as if looking back at the past; Wang Yanhui’s Chen police officer, hidden in the hazy foreground in the dense green leaves, eyes looking forward to explore the truth; Zhang Yu’s singer, wearing sunglasses and holding a microphone, whose mysterious identity plays an unknown role in the plot; Jiang Pei Yao’s Xueming girlfriend, wearing a plain plaid blouse, with a refreshing ponytail that sets off her face more clearly. Where her relationship with Wang Xueming will go remains to be revealed.

The film "Once Upon a Time in the Tropics" gathers together a group of outstanding actors, which can be called an annual "Versailles "-style cast, including both Chinese-language film actors and the best of the new generation of actors. In the poster of the upgraded characters, everyone shows the status of the characters in the way of" staring at the camera ", as if everyone is trying to peek into the truth of the summer night mystery. In addition, the poster is more full of strong retro atmosphere. The overall tone is reminiscent of the midsummer twilight in the old South, and the yellow-green tone of the film reflects a sense of nostalgia. It is worth mentioning that the English title of the film" Are You Lonesome Tonight? "is taken from the classic song of" Elvis Presley ". The nostalgic and tender style of the original song is closely in line with the tropical aesthetic that the director Wen Shipei wants to present.

It is reported that this song has also appeared in Chinese classic movies. The same summer lost, the same feelings of the past, "Tropical Past" pays tribute to the classic, what kind of story is about to present, it is worth the audience’s expectation.

　

Ning Haozan’s "Tropical Past" "Like Old Tea" is worth tasting, and director Wen Shipei pursues the creation of "a sense of flaw"

As early as 2017, "Once Upon a Time in the Tropics" was shortlisted for the venture capital project of the Shanghai International Film Festival and won the "Bad Monkey 72 Change Film Project Special Attention Project". After four years of polishing, the film will officially meet the audience this summer. Referring to the unique style and charm of the film, Ning Hao, the executive producer of "Once Upon a Time in the Tropics", said: "Director Wen Shipei controls a very modest aesthetic. He doesn’t mean that we tear something apart for you to see, but it has a kind of roundness and a kind of luster, which makes you feel that he has undergone some precipitation and is not ostentatious. You can’t see anything at a glance, this movie is very like some kind of old tea, you have to taste it in it."

Regarding the tropical texture that the film wants to capture, the director Wen Shipei said: "There is no way to recreate a past, but to find a breath in the process. The feeling of heat is an imagination, and we try to get closer and refine that feeling audiovisually. But contemporary video shooting tools have become very sharp, but they lose some sense of flaw, so we are instead pursuing a sense of destruction and flaw throughout the creative process."

2021 is the first year of the "14th Five-Year Plan". Facing the topic of "adhering to innovation-driven development, accelerating the construction of a new development pattern of a modern industrial system, improving the quality of economic development, and maintaining sustainable and healthy economic development", how can new infrastructure service providers represented by cloud computing better play the role of technology platforms, empower industrial economic innovation, and promote regional sustainable development? How to improve enterprise efficiency, promote regional enterprise cooperation, and consolidate the elements of enterprise development and innovation? Hong Fangming, president of Huawei Cloud China, expressed his views on the above issues in an interview with China Business News.

From a manufacturing power to a "smart" manufacturing power

After a year of unparalleled changes in a century, how enterprises can cope with difficulties and how to transform and upgrade has become an urgent proposition to be solved. The state has launched new infrastructure, and enterprises have accelerated their digital transformation. In the past year, we have seen a phenomenon. Those companies that can actively embrace digitalization and actively invest in online have shown a good development trend as a whole. On the contrary, those companies that use traditional methods and do not change the offline model, whether in sales or supply chain, are facing huge challenges as a whole. As people say, the SARS epidemic in 2003 accelerated the development of the consumer Internet, and the sudden COVID-19 pandemic in 2020 will accelerate the process of enterprises going to the cloud.

Today, our country is transforming from a manufacturing power to a "smart" manufacturing power. Enterprises need to transform and upgrade through digital means and digital empowerment in all aspects, such as research and development, production and manufacturing, supply chain, marketing, and service. This is also the key to how to change the current situation and how to take the next step under the current economic development situation. By visiting more than 30 provinces and cities across the country in 2020, we found that the technology gathered on the cloud is bringing great changes to the industry and society.

Urban industrial clusters need to move from small, scattered, and low-energy to high, refined, and cutting-edge

The development stage and state of a local industrial cluster determine the active level of a region’s economic development, and also reflect the situation of people’s livelihood and employment. It can be said that the regional industrial cluster determines the development, people’s livelihood and employment of a region, which is a very important development indicator.

In a conference held by Huawei Cloud in early January 2020, the director of the Bureau of Industry and Information Technology of a certain place said that although the local area has been ranked among the top 100 industrial zones in the country, the internal and external challenges in the past year have made him deeply feel the difficulties of the entire manufacturing industry: the cost of factory labor and land has been rising, the export situation has changed, the industrial structure is in urgent need of reorganization, and entrepreneurs have also expressed their urgent desire for transformation and upgrading.

Due to the limitations of formation conditions, industrial clusters in our country mostly focus on traditional processing fields, developing in the form of small workshops, and lack scientific and technological innovation. At present, traditional industrial clusters are facing challenges such as increasing labor costs, increasing social costs, and shortage of talents. Relying on simple replication for scale expansion, the form of spreading big cakes cannot achieve sustainable development. Industrial clusters need to move from small, scattered, and low-energy to high, refined, and cutting-edge development. How to complement R & D, market, supply chain, and service capabilities, realize supply chain elongation, and integrate upstream and downstream supply chains to obtain higher profits is the core appeal of industrial cluster development.

It is undeniable that there are many excellent enterprises in our industrial clusters that are doing very well and have reached a very top position in the world, but there are still a considerable number of small and medium-sized enterprises that have not reached this level. To evaluate the active level of an economy, it is not to have a few large enterprises, but more importantly to look at the activity of thousands of small and medium-sized enterprises. It is a key response for the country to solve employment and improve the overall economic active level. And the cloud platform that brings together various technologies and ecosystems just provides the technical business means needed for change.

Moving from simple connections to deeply empowering

Huawei has amassed a wealth of experience in the field of electronic information manufacturing over the past 30 years, whether it is from supply chain research and development, marketing, service, or in the industry precipitation of technology and marketing capabilities, Huawei hopes to use the cloud to bring its accumulated experience to empower various industries, empower society, and realize the company’s vision of bringing the digital world into everyone, every family, and every organization to build a smart world connected to all things.

In the process of business expansion, Huawei Cloud has learned about the characteristics of China’s economy itself and the characteristics of industrial clusters, and put forward the concept of "industrial cloud". Based on cloud infrastructure, an urban industry empowering platform that integrates industrial ecological resources to provide technologies, solutions, and industrial practice services provides a core driving force for promoting the integration of urban production and number, industrial innovation and upgrading, and reshaping the new industrial pattern. In essence, the demand for informatization and digitalization in today’s economic development has given birth to the concept and model of industrial cloud. At the same time, industrial cloud also responds to the question of where and how to transform and upgrade the industry in the process of supply, marketing, and service.

Different from the industrial Internet, which focuses on connecting various data and production materials of enterprises, so as to provide enterprises with the kinetic energy for transformation and upgrading; in addition to the connection function, the industrial cloud also provides enterprises with industrial empowerment and rich offline services, including the best experience of the industry, while combining a variety of advanced technical means.

Manufacturing cannot be simply defined by the production process. R & D and sales are actually key links in serving the manufacturing industry. Only with an enterprise system that completes research, sales, supply, production, and service can it be a true modern manufacturing industry. However, born out of domestic manufacturing enterprises such as processing with incoming materials, it is urgent to transform to modern manufacturing. Take the United States as an example. The proportion of manufacturing in the United States is relatively low, but if you look at the entire GDP of the United States, you will find that a very large part of the industry serves the manufacturing industry. This kind of manufacturing service industry accounts for about 50% of the overall manufacturing industry. If our country wants to move from a manufacturing power to a smart manufacturing power, it must work hard on this. In the face of the unclear concept of China’s industrial upgrading, the current situation of "hard" and "soft" is not simply to provide a cold technology to solve, but also to empower, to have a team to serve the industry, to teach these original traditional manufacturing industries how to achieve the next jump.

Huawei’s own industry is relatively wide, from the original service to operators, to government and enterprises, and then to consumer BG, you can think of Huawei as a traditional manufacturing industry, a high-tech enterprise, and a retail enterprise. Therefore, Huawei Cloud has rich accumulation in the above fields, including technology, marketing, supply chain, service and other aspects. Huawei Cloud will export these capabilities through the form of industrial cloud to empower the industry, which is also the biggest value point and difference point of Huawei Cloud.

A small step for enterprises to go to the cloud, a major leap for industrial clusters

At present, Huawei Cloud has landed in more than 120 innovation centers and industrial cluster bases across the country, and has joined more than 300 partners including MES, CAD, supply chain management, production management, software suppliers, etc., to provide digital transformation services for 17,000 enterprises.

During the COVID-19 pandemic, an electronic information enterprise in Dongguan, based on Huawei Cloud Industrial Internet, the big data platform created by the platform FusionPlant helped it to achieve an orderly resumption of work and production, ensuring the occurrence of 0 epidemic cases. At the same time, the efficient and convenient management brought by the visualization of the big data platform has also solved the remote control problem that many foreign employees cannot resume work in many process production links, and manages the production quality control of the entire production line. This is what we think is a very typical use case of an enterprise.

Facing the characteristics of China’s industrial economy and the key nodes facing the industry, how can its next jump be realized? For each industry, where is the future going and where is the next jump? This is the most concerned issue in the upstream and downstream industrial chains of urban industrial clusters.

The automotive industry, ICT industry, medical apparatus and pharmaceutical industry are the three pillar industries of the global economy. In the automotive industry, Huawei Car BU proposes to help car companies "build and sell good cars", use its own capabilities in research and development, manufacturing, marketing, etc., to drive the development of the upstream and downstream industrial chain of intelligent networked vehicles, and do some exploration and innovation work around automobile companies to help car companies transform and upgrade from the traditional fuel vehicle industry to the electric vehicle industry; in the electronic information industry, which is facing the pressure from low-end to high-end, Huawei helps the electronic information industry to achieve the next leap through its own practice; in the materials and pharmaceutical industries, many studies currently rely on a lot of laboratory experimental work, which is time-consuming and labor-intensive. Huawei Cloud makes use of its vast computing and IOT capabilities, combined with previous research and development achievements, to enhance the entire process of drug and material research and development.

With the industrial cloud empowering transformation and upgrading, through the continuous progress of technology, the continuous development of industry, and the continuous improvement of partner capabilities, we will provide the kinetic energy for the industry to upgrade and leap, and consolidate the "black land" of the intelligent world. We must embrace talents and continue to move forward, drive Chinese enterprises to take a small step in the cloud, lead industrial upgrading, and realize a big step in the leap of China’s industrial clusters, and truly realize a leap in the industry!

On the evening of the 2nd, China Evergrande and Hengda Properties announced on the Hong Kong Stock Exchange that the company has applied to the Stock Exchange to resume trading at 9:00 am on October 3.

On September 28, China Evergrande announced on the Hong Kong Stock Exchange that the company had received a notice from relevant departments that Mr. Xu Jiayin, the executive director and chairperson of the board of directors of the company, had been taken compulsory measures according to law on suspicion of illegal crimes.

On the morning of September 28, Hengda’s listed companies China Evergrande, Hengda Automobile, and Hengda Property collectively suspended trading on the Hong Kong Stock Exchange.

On the afternoon of September 27, Hengda’s listed platform stock price suddenly fell. As of the close, China Hengda fell 19%, with a total market value of 4.20 billion Hong Kong dollars; Hengda Automobile fell 20%, with a total market value of 6.10 billion Hong Kong dollars; Hengda Property fell 14.5%, with a total market value of 6.40 billion Hong Kong dollars. The total market value of the three major platforms is only 16.70 billion Hong Kong dollars.

A criminal law expert said in an interview with reporters at the time that according to Evergrande Group’s announcement, the company should have received a precise notice, and the notice classified Xu Jiayin as "suspected of illegal crimes" and was subject to coercive measures. It is common sense to guess that in the case of notification by relevant departments, the coercive measures taken are likely to be different from the "residential surveillance" misreported by foreign media.

The above-mentioned criminal legal experts said that in the context of the early investigation of Hengda Real Estate by the China Securities Regulatory Commission and the criminal coercive measures taken by the public security department against Hengda Fortune Du and other suspected criminals, the result of Xu Jiayin’s suspected illegal crime should not surprise too many people. Public opinion has paid more attention to "when" to take action. Judging from the current public information, the issues involved in him are likely to be related to multiple crimes, which are very complicated and may take quite some time to clarify.

It is worth noting that Hengda Automobile, which was suspended at the same time as China Hengda and Hengda Property, did not resume trading at the same time. On the last trading day before the suspension of Hengda Automobile, the share price was HK $0.56/share, and the total market value was HK $6.073 billion.

　　Recently, a statement issued by Linyi County Government of Shanxi Province on the improper marketing method of "Linyi Apple is unsalable" has aroused concern. According to the statement, a number of e-commerce companies released the marketing plan of "Linyi Apple is unsalable" and used the "sad card" to market Linyi Apple, which had a serious impact on the brand image of the local fruit industry, and the marketing content was exaggerated and inaccurate.

　　Beijing Youth Daily reporter saw that in WeChat official account and e-commerce platforms, there are still merchants who sell apples by slow sales as a marketing propaganda method. In addition to Linyi apples, there are also many businesses selling goods on the grounds of "apples are unsalable", "fresh bamboo shoots are unsalable" and "pineapples are unsalable", all of which use photos of the same old man as propaganda maps. In this regard, e-commerce customer service said that merchants may be suspected of infringing portrait rights, and the platform will also supervise the sales behavior of merchants.

　　"Linyi apples are unsalable"? Local claims exaggerate the facts.

　　On May 7th, Linyi County Government of Yuncheng, Shanxi Province issued a statement on the improper marketing method of "Linyi Apple is unsalable". According to the statement, recently, several e-commerce platforms released the marketing plan of "Linyi Apple is unsalable", and used the "sad card" to market Linyi Apple, which had a serious impact on the overall brand image of Yuncheng Fruit Industry. After comprehensive and in-depth verification, there are many exaggerations and inaccuracies in this information.

　　According to the investigation of Linyi county government, the videos and pictures selected for the report were all taken before 2016, and some of them also used the "posing" method to deliberately create a poor image of fruit farmers. In addition, in order to win the sympathy of consumers to the greatest extent, e-commerce deliberately creates the ugly characteristics of Linyi apples, and the apples presented are all inferior fruits with rust scars, pockmarks, black spots and cracks. These apples are the residual apples left after merchants screen and purchase high-quality apples, accounting for only a small proportion.

　　Linyi county government also said in the statement that some platforms have obtained materials with official seals of local townships, villages and fruit industry departments by improper means, and the contents of the statement are seriously inconsistent with the facts; Most platforms deliberately exaggerate the severity of slow sales of fruits, resulting in unreasonable fluctuations in apple prices.

　　According to the survey, the main sad brand is a common marketing method, and agricultural products such as pineapple in Xuwen, Guangdong Province and tangerine in Anhui Province have also been marketed in this way. The purpose is to attract people’s attention and gain consumers’ sympathy, which is convenient for fruit farmers to sell their fruits in a short-term and partial way, but it will damage the overall brand image and the overall interests of all fruit farmers in the long run.

　　Yesterday, the reporter of Beiqing Daily searched on an e-commerce platform and found that there are still many businesses selling Linyi apples in the name of "caring for farmers" and "40 million kilograms of apples are unsalable in Shanxi". One of the merchants who claimed to sell unsalable apples in Linyi sold 8.5 kg of apples at a price of 28.7 yuan, while the place of delivery was Shenzhen, Guangdong. On its publicity page, an old man wiped his eyes with his arm, holding several banknotes from 10 yuan and 5 yuan in his hand. In other pictures, there are a lot of moldy or damaged apples piled on the ground, and some elderly farmers are standing in the village with apples in their hands. There are many words in the propaganda, such as "fruit farmers are in a hurry" and "want to cry without tears". Commodity reviews show that many buyers are buying for the promotion of helping farmers. The seller admitted to the reporter of Beiqing Daily that the store address was in Shenzhen, but claimed that the photo was taken by "friends who arranged for employees to go to the place of origin".

　　Abused "slow-moving grandfather"

　　The reporter of Beiqing Daily learned that in addition to "Linyi apples are unsalable", there are many businesses selling goods by "promoting unsalable", including pineapple, fresh bamboo shoots and other foods, as well as blankets and other supplies. Surprisingly, many businesses use photos of the same old man, and this old man is also named "unsalable grandfather" on the Internet.

　　In one of the shops selling apples, the publicity picture shows the old man on the left, a large number of apples on the right and the words "Apples for sale, love and help" in the lower right corner. The price of apples is 27.9 yuan for 10 Jin, and the freight is 20 yuan.

　　Merchants said in the propaganda, "The local natural environment is only suitable for growing apples, and the economic income is very limited. The blocked traffic makes the fruit harvested every year rotten and can’t be sold. " Merchants are also equipped with photos of local fruit farmers, simple houses and a large number of apples.

　　In the publicity, the merchant said that the unsalable apples were produced in Yucheng County, Shangqiu, Henan Province, and the delivery place was Dashahe Town, Fengxian County, Xuzhou.

　　In this regard, the reporter of Beiqing Daily contacted the Yucheng county government. The government staff said that there are indeed many apples planted in the local area, but this year I have not heard of slow sales. "This is a marketing method, which exaggerates marketing." The staff of Dashahe Town Government said that there was unsalable agricultural products last year, but the inventory should have been processed by now. Even if there are still apples left, it is not recommended to buy them. At the same time, there is no traffic jam in Dashahe Town.

　　Another store selling "wild bamboo shoots" also used photos of "slow-moving grandfathers". The image of the old man in the propaganda picture remains the same, except that the picture on the right side is replaced by bamboo shoots, which are also accompanied by the words "seeking help".

　　The store told the reporter of Beiqing Daily that bamboo shoots came from Lingui District, Guilin, and he didn’t know the "slow-moving grandfather". He used this photo only because "he is good at pulling business", and many different businesses are also using the photos of the grandfather to attract customers. The store also said that because this kind of "wild bamboo shoots" only has a one-month listing period, it really helps the sales after using the photos of "slow-moving grandfather". "Fruits and rice noodles are used a lot, and we are not a family."

　　Later, the reporter of Beiqing Daily called the Lingui District Government of Guilin City. A staff member said that it was past the bamboo shoot digging season and had never heard of unsalable agricultural products. "Bamboo shoots are generally dug around Qingming, and now they are very old, and the local planting bases are not so large. Most of them are wild and it is impossible to produce unsalable products."

　　Through the image recognition search, after the reporter of Beiqing Daily entered the head photo of "slow-moving grandfather", he identified more than ten kinds of goods, and the types and origins of goods were different. In addition to apples and bamboo shoots, there were lemons, melons, loquats and other foods, even including rose seedlings, lamps and other commodities. The words "seek help" or "help us" were written on the lower right of the publicity map.

　　respond

　　The platform called "slow-moving grandfather" photos or suspected infringement.

　　Yesterday, the reporter of Beiqing Daily contacted the customer service of the online e-commerce platform. For the merchants to sell goods in the name of "slow sales", the customer service said that users can make complaints if they find that the situation is inconsistent, and the staff will handle it.

　　In addition, the company also has a large database, which will supervise the merchants. In addition, after seeing the photo of "slow-moving grandfather", the customer service staff said that many shops have used the photo of this grandfather as propaganda, which has been suspected of infringing on the right to portrait. "The shop owner has the right to protect his rights and interests if he finds it. The platform will definitely be responsible for him."

　　lawyer

　　Shops should bear corresponding administrative responsibilities for false propaganda.

　　Lawyer Han Xiao of Beijing Kangda Law Firm said that the store sells Linyi apples and other commodities in the name of unsalable sales, and the statement is seriously inconsistent with the facts, deliberately exaggerating the severity of unsalable fruit, which has been suspected of false propaganda as stipulated in the People’s Republic of China (PRC) Anti-Unfair Competition Law. According to relevant regulations, the operator may be fined more than 200,000 yuan and less than 1 million yuan; If the circumstances are serious, a fine of not less than 1 million yuan but not more than 2 million yuan may be imposed, and the business license may be revoked.

　　Regarding the issue of consumer rights protection, Han Xiao introduced that the false propaganda behavior of online stores violated consumers’ right to know. Apple and other commodities do not belong to the category of "seven days without reason to return", but consumers and stores can ask for a refund after consultation.

　　In addition, based on the intention of fraud, the store has carried out fraudulent acts of false propaganda, which has caused consumers to have a wrong understanding and bought their fruits based on the wrong understanding. If it has caused losses to consumers’ property (for example, consumers spend a high price to buy back inferior fruits with scars, pits and cracks), their actions are suspected of fraud.

　　Zhongxin. com, Jiangsu News, December 30 (Zhou Jianlin) On the evening of the 29 th, Suzhou Art Museum was full of youthful atmosphere. When the lights gradually dim, musicians slowly step onto the stage and pluck the strings, and an encounter between printmaking and music opens a beautiful journey.

" Xu Zhihan said that the print works on the spot also added a lot of inspiration to their creation.

　　Yuan Xin, who listened to the concert in the art museum for the second time, is a "post-90 s", and Suzhou Art Museum has become her new punching place.

At 0: 00 Beijing time on November 21st, 2022, FIFA World Cup Qatar 2022 will officially kick off in 2022. As a large-scale sports event in the world every four years, the World Cup always attracts many people’s attention.

However, most netizens may not always pay attention to football matches, watching people around them talk about the World Cup in full swing, but they don’t know how to join the topic. What should I do? Don’t panic,CCTV News World Cup series feature "Come and watch the ball! 》Take you for 10 minutes to learn something about football.

A few things you need to know about football and the World Cup.

one There are 11 players from each side in the football match, and these 11 players also bear different responsibilities. The goalkeeper is mainly responsible for guarding the goal; The defender is mainly responsible for the team’s defense; The midfielder is mainly responsible for organizing and dispatching, intercepting the ball and making offensive; The striker is mainly responsible for attacking the city and pulling out the village for the team.

2 The regular time of a football match is 90 minutes, and the first half is 45 minutes each.

three If the two sides are tied in the regular time and the winner must be decided, it will take 30 minutes of overtime.

four After the overtime, if the two sides are still tied, a penalty shootout is needed. The players on both sides decided the outcome of the game by shooting penalties at each other.

△ Penalty shootout-one of the most exciting links in football match

five In FIFA World Cup Qatar 2022, each team can change five players in a game at regular time. In the knockout stage, if you enter overtime, each team can get an extra substitution quota.

six However, the replaced players can no longer play, which is different from basketball and volleyball. So, if you see a player playing badly, don’t angrily accuse him: "Why don’t someone else go up quickly?" After all, substitution is a technical job, and the head coach of the team may be more worried than you.

seven There are no players such as Ronaldinho, Kaka, Beckham and Rooney in this World Cup. They used to be the stars of the shining World Cup, but now they have hung up their boots and retired.

eight There are no Jordan, James, Curry and Durant on the American team. They are all basketball players. Don’t confuse them.

nine There are no clubs such as Real Madrid, Barcelona, Manchester United and Bayern in the World Cup. Players only represent the associations of their countries or regions.

10 In addition to Italy’s regret, teams familiar to everyone, such as Brazil, Argentina, France, Germany, Spain and England, all came to Qatar. Cristiano Ronaldo, Lionel Messi, Neymar and Mbappé are not absent. The group list of the World Cup finals is listed by Xiaobian for you:

Do you still use "staying up late to explode your liver" in this World Cup?

A bad news and a good news.The bad news is that there are still many wonderful games in this World Cup that kick off at 3:00 am Beijing time. The strong dialogue in the group stage (for example, Spain VS Germany) and almost half of the competitions in the knockout stage are arranged at this time. The good news is that the kick-off time of the final is 23: 00 on December 18th, Beijing time, and the finish time is about 1: 00 on December 19th. In this final, you don’t need to set an alarm clock at two or three o’clock at night to watch the whole game with sleepiness.

I wonder which one to watch. Xiaobian helps you with your ideas.

France is the defending champion of the World Cup, with many stars, while Denmark ranks 10th in the world. In last year’s European Cup, it also reached the top four, with strong strength. It is worth mentioning that in the last three encounters between the two sides, the Danish team remained unbeaten against France with 2 wins and 1 draw. This game is a strong dialogue worth looking forward to.

Two traditional strong teams, both of which have won the World Cup, will stage a "Mars hit the earth"-like confrontation in the group stage. Although the two teams are close in world ranking and paper strength, Spain beat Germany 6-0 in the last European League match. In this World Cup, there is no shortage of highlights in the contest between the two teams.

Both teams are led by the world’s top strikers. Who can lead the team to victory, lewandowski of the Polish team or Messi of the Argentine team, deserves attention.

In the 2002 World Cup in Korea and Japan, the two teams competed for qualifying in the final round of the group stage. In that game, two players of Portugal were sent off by red cards, while South Korea scored a goal in the dominant position, which knocked Portugal out of the group. Now, 20 years later, what will be the result of the second match between the two sides in the history of the World Cup? The game is worth watching.

For many people, when watching a football match, if you don’t know any of the 22 players on the field, you may be sleepy before you see half of the 90-minute game. How to choose when you don’t watch the ball and face 32 strange teams and players?

If you only know Messi and Cristiano Ronaldo …

For those who rarely watch football and only know Ronaldo and Messi when it comes to football, choose to watch.Portugal, ArgentinaThe match between the two teams is a good choice. Of course, in addition to these two core players, the two teams also have many world-class stars in other positions.

Portugal has a luxurious lineup, with midfielder Fernandez and defender Diaz having great strength in their respective positions. Cristiano Ronaldo, who is 37 years old, has not been in a satisfactory state recently. This World Cup is also the last chance for the star who has been playing for Portugal for nearly 20 years to realize his dream of winning the World Cup.

Similar to Cristiano Ronaldo, this tournament is also likely to be the 35-year-old Messi’s last World Cup. Unlike Cristiano Ronaldo, Messi has been in relatively good shape recently. In addition to Messi, lautaro Martinez is a stable attack point for Argentina, while Romero and other players can provide Argentina with defense protection.

If you are keen on enjoying the feeling of victory …

Brazil and France, the two favourites to win the World Cup, can pay attention.

Brazil has a team that can hit the championship. In many positions, there are excellent players in the team, even substitutes, who can reach world-class standards. The only fly in the ointment is the position of full-back, and the relatively short talent pool may become Brazil’s weakness.

The French team has the world’s top player Mbappé, the young midfield star Chuameni, and the defensive line with a talent blowout. However, the football match has never been a competition of paper strength. In this year’s European League, France lost to Denmark twice, and it is hard to win in the face of Croatia. The strength of the players in the French team can be said to be the top 32, but how to arrange a suitable starting lineup and let the players exert their greatest strength is also a problem that coach Deschamps needs to consider.

If you want to chase an unpopular team …

If you don’t like conformity, then Xiaobian recommends it to you.Senegal, DenmarkTwo teams that are expected to make great achievements in this World Cup.

Senegalese, the African champion, has world-class stars such as coulibaly and Eduardo Mendi in the team, and the team members basically play in the five major leagues in Europe, so their strength cannot be underestimated. The withdrawal of the top star, Mane, due to injury will affect the strength of the team to some extent, but in the group stage, Senegal still has strong competitiveness.

Denmark ranks 10th in the FIFA world rankings. In last year’s European Cup, the team reached the top four without Eriksson, the core of the team. Today, Eriksson has recovered from injury, and players such as Heibel are in the prime of their careers, which makes Denmark a team worth looking forward to in this tournament.

If you pay more attention to face value …

For fans who are concerned about players’ face value, Xiaobian recommends several "drop-dead gorgeous" in their respective teams.

Of course, the judgment of face value varies from person to person. In the one-month competition, I believe you will also find your own football star.

As a true fan, if you see beautiful passes and goals, you can only say "this ball is awesome!" " It would be unprofessional. Xiaobian has prepared a set of necessary terms for you to watch the ball, turning the commentator’s "heavenly book" into an easy-to-understand language and chatting happily with friends.

formation

In a game, we often hear commentators mention 4-4-2, 4-3-3, 4-2-3-1, 3-5-2 and other formations. In most cases, the number at the top of the formation name represents the number of guards, the number at the bottom represents the number of strikers, and the number in the middle is the number of midfielders, excluding the goalkeeper. As shown in the figure below

According to the team’s staffing, tactics and opponents’ situation, the head coach may arrange various formations. "Changing the array" can often become a magic weapon for a team to defeat the enemy.

"Forbidden area", bottom line and sideline

Look at the picture ↓↓↓↓

corner

The defender kicked (touched) the ball out of his own baseline and the attacker got a corner kick.

△ Corner kick should be taken from a specific corner kick area (data map)

penalty kick

The defender fouls or intentionally handballs in his own restricted area, and the attacker gets a penalty.

wave of the world

It means a wonderful goal. If you see a shocking and unforgettable goal in the game, you can say, "This is a world wave!" "

"Score twice", "hat trick" and "Big Four Happiness"

A player who scores two goals in a game is called "scoring twice", scoring three goals is called "hat trick" and scoring four goals is called "big four happiness".

own goal

Our players kick (throw) the ball into their own goal to help their opponents score.

△ There is no doubt that this is indeed an own goal that has appeared in the official competition.

VAR

Video Assistant Referee (video assistant referee). Through video playback technology, they help the referee to correct mistakes and omissions and improve the accuracy of the penalty.

△ In the last World Cup, VAR already appeared in the competition.

yellow card

When a player commits a relatively serious foul, the referee will show a yellow card to warn him. Some commentators also call it the "Golden God of War Card".

red card

If a player commits a serious foul or gets two yellow cards in total, the referee will show a red card. Players who get a red card must leave the stadium, which some commentators also call "the Ruby God of War Card".

offside

Offside is one of the most complicated rules in football. To put it simply, the commentator said that the ball was offside, so nine times out of ten it was offside …

Seeing this, you must have known something about football and this World Cup. Tomorrow at 0: 00 am, prepare fried chicken for drinks, or put a hot pot on the shelf, and watch and talk about the ball together!
