CCTV News:From December 18th to 20th, the final of the 1st National Postdoctoral Innovation and Entrepreneurship Competition was held in Foshan, Guangdong. This is the largest, highest level and widest coverage national post-doctoral innovation and entrepreneurship competition held since the implementation of the post-doctoral system in China, and it can also be said that it is a competition between super brain in our country.

The contestant on the road show is named Dink, and the project he shows is the "high-speed, high-definition and three-dimensional machine vision system" developed by him and his team in 10 years.

Judges:I want to ask, what are our specific application scenarios?

Player:At present, our main application scenarios are more guided by robots.

In the past, the recognition speed of domestic robot vision system was slow, and most of them could only be designed according to fixed programs, and repeated sorting and handling could not be carried out. The 3D "eyes" developed by the Dink team can identify objects in all directions and greatly improve the vision level of the robot. Dink’s project also got a high score in the roadshow of the Entrepreneurial Competition.

Dink, a contestant in the 1st National Postdoctoral Innovation and Entrepreneurship Competition:Contacting these technical experts and investors and interacting with them can bring some new ideas and even some new application scenarios.

The project roadshow, on-site defense, and on-the-spot bright points, 47 teams competed for the gold, silver and bronze awards in this competition, and the total prize money of the competition was more than 12 million yuan. More importantly, the contest gave many excellent "ideas" a chance to land.

Tang Yong, the expert judge of the contest:How can we cross and inspire each other with our own ideas and ideas, and truly achieve our originality by facing the international (frontier of science and technology)?

The title contest focuses on the practical problems of enterprises

The post-doctoral innovation and entrepreneurship competition has attracted wide attention. The characteristic of this competition is that manufacturing enterprises give questions, and postdoctoral fellows come to answer them, which can be described as "facing the market" and "professional and accurate". Let’s take a look again.

The title contest is one of the highlights of this competition. In the end, 23 technical requirements and 230 applicants entered the finals, and the solutions were displayed on the spot for the problems raised by listed companies.

The way of the competition is similar to that of the Innovation and Entrepreneurship Competition, but the content of the competition is more specific, which solves the practical problems faced by enterprises. This postdoctoral team from Shenzhen brought the world’s leading 6G technical solution to expose the research topics of mobile communication system and key technologies.

Contest contestant Zhang Chenyao:The leading place lies in the low-power algorithm, because the energy consumption on the satellite is limited. We adopt the low-power intelligent technology of wireless sensor network and put it on the on-board as low-power calculation, and achieve the effect of fusion of calculation results through the combination of multiple satellites.

After the completion of the road show, the expert judges of the contest will also ask questions on the spot, and score on the spot around the core competitiveness of the project technology, the effectiveness of the project team, the feasibility of the implementation plan, etc. If the list is finally successfully unveiled, the total amount of rewards will exceed 50 million yuan.

Since the beginning of this year, the state has promoted the implementation of the digital transformation partnership action to empower traditional enterprises to upgrade digitally and intelligently; The implementation of intelligent manufacturing engineering and digital empowerment of small and medium-sized enterprises will enable digital technology to better empower the development of large, medium and small enterprises, which will also create a bigger stage for postdoctoral students.

　　Cctv news Experts from the Forum of 30 Circulation People in China put forward an idea to encourage China supermarket enterprises to enter the markets of five Central Asian countries along the "Silk Road Economic Belt" and establish a "Silk Road Supermarket". To this end, Ma Longlong, vice chairman of the 30-member China Circulation Forum, and Zhi Li, a young expert, wrote to the leaders of the Ministry of Commerce, proposing to establish a "Silk Road Supermarket" and held an expert seminar.

　　According to Ma Longlong, in the summer of 2014, they led a team to five Central Asian countries to investigate the development of local commerce and trade circulation industry, and deeply felt the urgent desire of the local government and people to vigorously develop commercial infrastructure to meet the growing consumer demand. As the "One Belt, One Road" strategy has entered the stage of full implementation, supporting and guiding China supermarket enterprises to enter the Central Asian market along the "Silk Road" is in line with the interests of all countries and has broad prospects.

　　"Construction ‘ Silk Road Supermarket ’ It is of great significance. " Ma Longlong analysis:

　　— — It is conducive to the smooth implementation of the "Belt and Road" strategy.

　　Building a "community of interests" and "community of destiny" of relevant countries is one of the starting points of the "Belt and Road" strategic concept. The construction of "Silk Road Supermarket" is a concrete form of strengthening economic and trade exchanges between China and countries along the route, which can effectively promote the implementation of the strategy and tap the potential of cooperation between China and countries along the route.

　　— — It is conducive to creating a new situation in China’s opening up. China has made remarkable achievements in opening up to the outside world, but the overall pattern is "fast in the east and slow in the west, strong in the sea and weak in the land". The construction of "Silk Road Supermarket" is an important measure to accelerate the pace of China’s opening to the west and help inland border areas move from the edge of opening to the forefront.

　　— — Is conducive to establishing a new diplomatic image of China. Countries along the "Belt and Road" are rich in energy, but daily necessities and fresh food are relatively scarce. The construction of "Silk Road Supermarket" is conducive to reversing China’s diplomatic image with the main purpose of "purchasing resources" and enhancing its diplomatic affinity.

　　— — Conducive to China’s circulation industry going out. In July 2012, the State Council put forward the strategy of "going out" for the circulation industry. The construction of "Silk Road Supermarket" will be a vivid practice of this strategy and will also provide valuable experience for later enterprises.

　　In view of the characteristics of the five Central Asian countries, such as sufficient purchasing power, vast territory and sparsely populated, Ma Longlong believes that a perfect supply chain is one of the key factors for successfully building a "Silk Road Supermarket", and small and medium-sized supermarkets should become the main format of the "Silk Road Supermarket", while private enterprises are more suitable as the main business entities of the "Silk Road Supermarket". Ma Longlong suggested that the government should encourage and guide domestic private supermarket enterprises to go out and build small and medium-sized supermarkets mainly engaged in daily necessities and fresh food in countries along the Belt and Road; The government has invested in the construction of transportation infrastructure and public welfare logistics and distribution centers in countries along the route, and introduced preferential policies for the import and export of goods to facilitate the supply of goods; Five Central Asian countries will be used as construction pilots, and when they are mature, they will be deployed to enter the markets of Turkey or other countries.

　　Chinanews. com April 13 th (Zhongxin Finance reporter Zuo Yuqing) Gold fell!

　　On April 12, the international gold price that once broke through the $2,400 mark plunged in intraday trading, and London spot gold closed down 1.25% to $2,343.29 per ounce; COMEX gold futures closed down 0.53% at $2,360.2 per ounce.

　　Affected by this, on April 13th, the domestic gold jewelry price dropped. On that day, the gold jewelry price of Lao Fengxiang was 737 yuan/gram, and that of Chow Tai Fook was 736 yuan/gram, which was about 10 yuan/gram lower than the previous day.

　　International closing price of gold and silver on April 12.

　　What happened?

　　On April 10 -12, the gold price, which had maintained an upward trend before, took a roller coaster ride.

　　On the evening of April 10th, the latest ——CPI data, the most critical inflation data before the Federal Reserve’s May resolution, was released. The CPI of the United States rose by 3.5% year-on-year in March, which was higher than the market expectation of 3.4%, which means that the possibility of the Fed cutting interest rates in June decreased.

　　After the data was released, the international gold and silver prices fell briefly. However, the US PPI growth rate of 2.1% in March announced on the evening of 11th was slightly lower than expected, and the chain growth rate slowed down to 0.2%, which made gold and silver "rebel" again.

　　From April 11th to 12th, the international gold price returned to the upward trend. On the 12th, COMEX gold reached a maximum of $2,448.8 per ounce; Spot gold in London once reached $2,431.78 per ounce, both hitting record highs.

　　However, just as COMEX gold and London spot gold both broke through the $2,400 mark, several Fed officials said that the interest rate cut would be later than previously expected.

　　Federal Reserve official Collins said that it is now expected that the Fed will cut interest rates later than previously expected. Federal Reserve official goolsbee pointed out that the United States is in a contradictory environment, and the Fed must reduce the inflation rate to the target level, and many inflation data are higher than expected. He does not want to impose restrictions on the actions that the Fed may take in future meetings; Federal Reserve official Daley believes that at present, the Fed is moving towards the goal of reducing inflation to 2% as gently as possible, and there is no urgency to cut interest rates.

　　The voice of Fed officials made the re-rising gold dive again at a high level. London spot gold once rose by nearly 2.5%, but then plunged sharply, with a daily decline of 1.25% to $2,343.29 per ounce; COMEX gold futures once rose more than 3% in intraday trading, and finally closed down 0.53% at $2,360.2 per ounce.

　　The skyrocketing gold deviates from "common sense"?

　　It is worth mentioning that the previous skyrocketing performance of gold was regarded as deviating from "common sense".

　　Some insiders believe that gold and the US dollar are rarely "competitive" with each other, reflecting the long-term hidden concerns of the US dollar credit.

　　In January this year, the U.S. Treasury Department issued a report that the total amount of U.S. Treasury bonds reached $34 trillion for the first time, five years ahead of the previous forecast of the U.S. Congressional Budget Office. Some foreign media pointed out that this indicates that it will face political and economic challenges in improving the balance sheet of the United States in the next few years.

　　The expectation of interest rate cuts in the United States is not convincing: since 2023, the frequent revision of non-agricultural data in the United States and the impact of part-time jobs on data have reduced the market’s trust in non-agricultural data; At the same time, although the US CPI data exceeded expectations, the US PPI data released in March on the evening of the 11th suspended inflation anxiety.

　　In addition, under the geopolitical influence and high interest rate environment, the continuous purchase of gold by global central banks is also regarded as an important factor affecting the trend of gold.

　　Huatai Securities’ collection team believes that the central bank’s purchase of gold not only reflects the recognition of the safe-haven nature of gold, but also shows the concern about the stability of the traditional monetary system under the continuous expansion of the Fed’s balance sheet.

　　So, does this mean "the collapse of the dollar credit system"?

　　Pan Helin, an economist, told Zhongxin Finance that the US dollar will remain an international currency for a long time to come. "The gold standard cannot return, so the performance of gold price is the cyclical performance of the US dollar, and it is affected by the cyclical fluctuation of risk-free interest rates."

　　Buy or sell?

　　"Gold will prove itself"-this is a ridicule from gold holders. However, how much room for gold to rise after a "violent" callback? Should investors buy or sell?

　　Industrial Securities pointed out that the general public accounts for a relatively high proportion of gold investors, and professional investors and the public are divided in their perception of the value of gold investment. The judgment of global central banks on the value of gold will include political factors, but if the price of gold deviates too much from the actual value, central banks will also consider the cost and risk of allocating gold.

　　Zhongxin Finance noted that although the price of gold fluctuated in the short term, the scale of several gold ETFs such as Huaan Gold ETF, Bosera Gold ETF, E Fund Gold ETF and Cathay Pacific Gold ETF has reached a record high. According to third-party data, from March 1 to April 12, gold ETFs and gold stock ETFs attracted more than 12 billion yuan.

　　On April 12, Shanghai Gold Exchange issued an announcement, announcing to increase the margin ratio of gold deferred contracts, the price limit and the margin of performance-guaranteed inquiry contracts. At the same time, investors are reminded to do a good job in risk prevention, control their positions reasonably and invest rationally to ensure the stable and healthy operation of the market.

　　Pan Helin believes that it is more likely that the Fed will postpone the interest rate cut at present, but the persistence of the continued rise in gold prices still exists, because although the Fed may delay the interest rate cut, it is inevitable that interest rates will peak. (End)

Tianzhou-1 data map (photo by Gao Jian, Institute 512, Fifth Academy of Aerospace Science and Technology Group)

Cctv news On April 20th, China’s first cargo ship Tianzhou-1 was successfully launched. On April 23rd, Tianzhou-1 successfully rendezvous and docked with Tiangong-2, the first real space laboratory in China. The smooth implementation of the space laboratory mission indicates that China is steadily marching towards the "space station era".

It is reported that Tianzhou-1 was developed by the Fifth Academy of Aerospace Science and Technology Group (China Academy of Space Technology) and launched at Wenchang Satellite Launch Base in Hainan. After liftoff, it was monitored and controlled by Beijing Flight Control Center. Behind the success of the "Tianzhou-1" space mission is a group of China astronauts who have worked hard, step by step, and created numerous fruits through independent innovation and self-reliance.

There are such a group of young people in the overall development team of Tianzhou-1 cargo spacecraft in the Fifth Academy of Aerospace. Some of them have been attached to Tianzhou since they were in their twenties, and they grew up with Tianzhou from blueprint to first flight. After six years of hard work, they drew the Tianzhou-1 cargo spacecraft in the plan, built it in the factory building and erected it on the rocket. They used their most precious years and unrepentant youth to lift this boat of hope that carries the future of China’s manned spaceflight project.

"Closed door" for a month, manned space flight is seize the day.

Any complex space mission is inseparable from scientific and thorough top-level design, and the overall system team is responsible for the top-level design of the overall development of Tianzhou-1 cargo spacecraft.

After six years of cold and heat, the overall work of the system runs through the model. In the stage of project demonstration, the overall team of the system needs to come up with a high-level skyboat scheme on the basis of inheriting Shenzhou and Tiangong. In the initial sample stage, the team completed the detailed design scheme of fully sealed and semi-open cargo ships in parallel, which "finalized" the classification of future cargo spacecraft; After successfully completing the large-scale tests such as the mechanics, heat, electromagnetic compatibility and large-scale system connection of the cargo ship, the team began to engage in intense double-track operations. Some designers went to Wenchang base to carry out the joint training of fully sealed ships, while others stayed in Beijing to continue to carry out in-depth research and development of semi-sealed ships … …

This team is responsible for the system scheme, flight scheme, technical status, large-scale test, technical process, reliability and safety, cargo loading, etc. of Tianzhou-1 cargo spacecraft. It is no exaggeration to say that the overall team of the system has concentrated most of the creators of Tianzhou-1, and it is their wisdom that has enabled Tianzhou to move from scheme to production, from large-scale test to model first flight. The "God Boat" that makes up this team is a group of young party member, whose youngest is 32 years old and the oldest is 35 years old.

From the layman’s point of view, the successful launch of the Tianzhou-1 cargo spacecraft may be a feat of refueling in space, but for astronauts, the inherent improvement of the cargo ship makes them more proud. Zhang Jian, deputy director of the overall research office of manned spacecraft, said that the overall team of the system has designed a brand-new track for cargo ships, which is more fuel-saving and has stronger docking adaptability.

Before each spacecraft development turns to a new stage, the overall system team will have a "convergence", just like closed-door training. What impressed Zhang Jian the most was that before Tianzhou No.1 left the factory, nine colleagues "isolated themselves" in a conference room, working from eight o’clock in the morning until after midnight for more than a month. For more than a month, colleagues from my hometown simply lived near the unit to save time, and everyone ate some biscuits and bread when they were hungry in the middle of the night.

In the "closed door", the team systematically summarized and verified, checked the product status, and prepared for the mission, and checked the massive data of 148 system-level test projects bit by bit, and deduced 107 key events, more than 4,800 command-level actions and 328 flight control plans in the flight mission one by one … … Along the way, they didn’t have time to be quiet, but they were more like Dai Yue, accompanied by servants chasing time. They won confidence and the ability to design the future in the process of manned space flight.

Tianzhou-1 was successfully launched, and the staff at the electric survey site took a group photo to celebrate.

Localization of Core Components Interpreting Life with Strong and Weak Electricity

What is the overall team responsible for? It can be summed up in one sentence that they are in charge of all projects related to "electricity". Yu Lei, Li Guangri, Wang Jinghua, Wang Hongjia, and Sun Ben have their own ideas from energy system, information system, top-level software design to electromagnetic compatibility design. From the beginning of dealing with Tianzhou-1, they have paid hard work that ordinary people can’t imagine.

Whether it is the application of 100-volt high-voltage fully distributed distribution system and high-voltage lithium battery, or the "space-based" measurement and control system of cargo ships and the internal Ethernet high-speed information system, and then planning the power supply and information flow separately for the load, from strong electricity to weak electricity, what the overall team of electricity needs to establish is a set of brand-new electronic and information systems. "I can’t learn from it, starting from scratch." Chief designer Yu Lei said. At the beginning of the development, qualified power supply modules and high-speed transmission wires that meet the requirements could not be found. They ran all over the manufacturers and did all kinds of tests just to pave the way for the future.

There is no domestic power supply that meets the requirements, and the team will jointly develop it with the manufacturers on the basis of a lot of research. In the end, Tianzhou-1 adopted the domestic 100V thick film power module for the first time on the domestic spacecraft. This power module broke through the foreign blockade restrictions and was applied to all the key electronic stand-alone machines of the whole ship, laying the foundation for 100V high-voltage transmission, optimizing the power distribution equipment and cable weight of the whole ship for dozens of kilograms, and promoting the localization process of spacecraft core component design.

Tianzhou-1 electric survey site

Entering the normal sample stage, the work goal has become to improve robustness and reliability. In order to reassure myself completely, with the help of the designers of the overall circuit subsystem, Wang Lintao and Li Huijun, the team began to measure the resistance of tens of thousands of nodes in the whole ship after the night work, which lasted for several days. This kind of test, they did it again before power-on, and they did it again for the third time after the ship’s equipment software was upgraded. Yu Lei proudly introduced: "From the beginning, it was very reassuring to power up the whole ship!"

From the beginning of November 2016 to April 2017, the whole ship has been electrified for more than 1,900 hours in more than five months. Behind the converted average of more than 10 hours a day, there is a long-term continuous work with a total length of more than 12 hours a day. These are only part of the overall work of electricity. Yu Lei said that as long as the cargo ship is connected with a little electricity, his team must be there.

Six years of grinding a sword "digital boat" into reality

The machinery is generally responsible for the work, some of which go straight to the top, and some of which are detailed to the parts, and the core members of this team are only three young people — — Jia Dongyong, Guo Junhui and Han Bin.

Hundreds of designers, on a unified digital platform, design their own parts according to common rules and their respective authorities, without paper drawings and documents and manual approval. Through the digital process, the data of "Digital Skyboat" is transmitted to the manufacturing equipment, and various real structures, components and pipelines … … This used to be a slightly hopeful future, and the only way to the future was opened by the overall mechanical team.

In the past six years, under the guidance of old experts, the overall mechanical team has created many "revolutionary" precedents, one of which is the first to promote three-dimensional digital development. Jia Dongyong proudly said: "We are coordinating our work now, without paper documents, and directly open the computer to discuss the model."

What makes the machinery equally proud is their freight guarantee design. The cargo ship is a brand-new model, ranging from loading scheme, layout balance, small arrival package design to fine interface design, all from scratch. Nowadays, the cargo ship with a full load of 13.5 tons has an excellent cargo ratio of 0.48 and the hanging eccentricity level is kept at 3 mm. Behind these impressive data, it is the crystallization of the overall wisdom of machinery.

Group photo of the word "Tianzhou" in Tianzhou No.1 team group.

Regard Tianzhou No.1 as their own children, devote their efforts to grow up with them, but when it comes to family, these "desperate Saburo" are silent again. Some of them think of their parents who are seriously ill in their hometown, some are ashamed of their children who have been sent back to their hometown, and some are full of apologies for silently bearing too many wives … … This is a group of glorious and great astronauts, but also a group of ordinary astronauts. On the road of manned engineering and the journey of becoming a space power, they are working hard without regret. They lifted Tianzhou-1, which traveled in space, and also wrote Chinese’s own pride.

　　Qi bangs, dark circles, a Beijing film, and teeth from time to time. When Nezha, who stepped on hot wheels, came to the audience, the 2019 summer file finally ushered in a domestic film Ne Zha that really made the market "dry up". The film was released yesterday, and with the good reputation of large-scale fermentation in the previous screening, the box office exceeded 140 million yuan on the first day.

　　Jiaozi, the director of the film, was born in 1980. He has been a loyal fan of cartoons since childhood. In 1979, his masterpiece "What’s wrong with the sea" was his favorite. Being obsessed with animation, he graduated from West China University of Medical Sciences (now West China Medical Center of Sichuan University) and "abandoned medicine to pursue literature" and embarked on the road of self-taught animation creation. In this process, he had encountered a lot of prejudice and contempt from outside, and he liked Nezha, a bold character, since he was a child, so jiaozi came up with the idea of creating a new version of Nezha.

　　At the beginning, jiaozi wrote the script outline fairly smoothly. After sending the animation of Fang Caitiao House, the main producer of the film, everyone thought it was done well. Jiaozi quickly wrote the first version of the script while the iron was hot. "At that time, I was quite confident. I didn’t think it would change much. They called and said that it was well written. Why don’t you come and have a meeting? As a result, various problems of the script were pointed out at the meeting. " However, the script is an organism, which affects the whole body. A slight change in one place may affect the whole article. In this way, in nearly two years, the script was revised to the 66 th edition before it was finalized.

　　Nezha, the leading actor, and the role of "playing soy sauce", Ne Zha has made a brand-new design different from the previous version. Nezha’s image was nearly 100 editions. Later, when the final edition was selected, some people thought that this little Nezha with eight eyebrows and dark circles was too ugly to accept, but jiaozi thought that such a design was exactly in line with the central idea of the film, that is, "breaking stereotypes and turning around fate".

　　Aobing, the third prince of the Dragon Palace, has always appeared as cannon fodder killed by Nezha in previous stories, but in this film, his scenes have greatly increased and he has become a "spirit bead" role in contrast to Nezha, the magic pill. In appearance, Nezha is a combination of man and demon, while the opposite Aobing is a combination of man and fairy, with elegant figure and elegant manners, and a beautiful young image. In action design, jiaozi drew lessons from the series of movies "Huang Feihong" starring Jet Li: Ao Bing’s fighting refers to Huang Feihong, which is chic and light, and has its own master style; Nezha’s movements refer to Ghost Feet 7, and he is wild and passionate, chasing after him.

　　In the audience’s impression, Tai Yi, a real person with a sage like style, completely subverted his image this time, with a big belly and a mouthful of "Trump", which became the comedy of the whole film. For such a change, jiaozi revealed that the founder had also carefully thought about it. The Dojo of Taiyi, Qianyuan Mountain Jinguangdong, is located in Jiangyou, Sichuan. He said that the Sichuan dialect is not groundless. As for the pair of clown boundary animals who are in charge of guarding Nezha in the film, the image comes from the cultural relics of the Yin and Shang Dynasties unearthed from Jinsha site in Sichuan.

　　As a veteran movie fan who has read countless films, jiaozi designed many bridges and details in the film to pay tribute to his favorite classic works. For example, Nezha’s double-ball-head modeling and Ao Bing’s double-hammer weapon come from the 1979 edition of What makes the sea noisy, and Nezha gets the dance gun after mixing the sky silk and the fire-pointed gun, which completely reproduces the animation of that year; The action of the enchantment beast to pick up the enchantment with weapons is based on the domestic classic animation "Make a scene in Heaven"; Taiyi real people read "Self-cultivation of Immortals" and the people in Chentang County were surprised to bite their mouths. At first glance, they knew that they were paying tribute to Stephen Chow’s comedy; As for Nezha playing tricks on Ao Bing and Shen Gongbao with transformation, he was inspired by Jackie Chan’s masterpiece "Shuanglong Club" … … The extensive use and reference of old Hong Kong films, China traditional animation and even Hollywood animation has made the film form a mixed style.

　　It is worth mentioning that the names of more than 60 domestic animation companies appeared in the credits, and the number of people involved in the production reached more than 1,600, which is the film with the largest number of participants among domestic animations so far. This not only represents the current situation of China animation industry, but also is a collective self-help for the whole industry. Jiaozi said frankly that the productivity of domestic animation is limited, and many large companies are reluctant to accept Nezha’s order because the budget is too small, and they may lose money. They had to distribute it to a large number of small companies, some contracted the whole scene, some only made animations, models or special effects, and some companies were even willing to help at a loss, which made jiaozi very moved. "Everyone is holding on, hoping that domestic animation can produce more fine products, so that more people are willing to invest in this industry, can support themselves, and can live more proudly."

　　"The COVID-19 epidemic can be called a pandemic in terms of characteristics." On March 11th, local time, at a regular press conference held in Geneva, Switzerland, Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, announced this judgment, which attracted global attention.

　　WHO defines pandemic as "the widespread spread of a new disease around the world". At the end of January, WHO declared the COVID-19 epidemic as a "public health emergency of international concern", and now it has been declared as a global pandemic, which means that the global spread of the virus has not been curbed, and the severity and difficulty of response have increased.

　　The alarm bell has sounded, and the global anti-epidemic has reached a critical moment. In a speech, UN Secretary-General Guterres said that this announcement by WHO is a "clarion call for global action". In the face of the epidemic, it is urgent for all countries to join hands to fight.

　　What is a pandemic?

　　In 2010, the WHO website gave a simple definition of pandemic, that is, a new disease spread around the world. Among them, influenza pandemic refers to the spread of influenza virus around the world, and most people have no immunity to the virus.

　　Prevalence, infectivity and trans-regionality — — According to the standards currently adopted by WHO, a pandemic must meet these three conditions. The pandemics recognized by WHO or recognized by history mainly include the Black Death in 14th century, smallpox at the end of 19th century, and Spanish influenza in 1918. The latest pandemic recognized by WHO was the outbreak of influenza A (H1N1) from the United States and Mexico in 2009, which affected 214 countries and regions around the world for 16 months, infected at least 60 million people and caused 18,500 deaths.

　　Pandemic is not a strict definition, but a vague concept; The main consideration in defining a pandemic is not the virulence and mortality of the virus, but the scope of the virus. WHO originally divided the influenza warning level into six levels, of which five to six levels were human-to-human transmission worldwide, and the highest level was influenza pandemic, which indicated that an influenza virus broke out at the community level in at least one country outside the origin of the epidemic and posed a global spread threat.

　　In an interview with the media in late February, Jasarevic, a spokesperson for WHO, said that at present, WHO no longer uses six-level classification to evaluate infectious diseases such as influenza, but has changed to four stages: intermittent phase, alert phase, pandemic phase and transition phase.

　　In that case, why did WHO still declare COVID-19 as the first "pandemic" coronavirus infectious disease?

　　Margaret Harris, a spokeswoman for WHO, once said, "If the epidemic trend in novel coronavirus meets the standards of previous pandemics, WHO may use ‘ in communication; Pandemic ’ The word ",and the current epidemic situation has met the epidemiological conditions that constitute a global pandemic. At the same time, Tedros Adhanom Ghebreyesus also gave the judgment basis at the regular press conference on March 11th: first, based on the current spread speed, scale and severity of the virus; second, there are still countries that have not paid enough attention to and failed to prevent and control the major epidemic.

　　The global epidemic situation is worrying. In the past two weeks, the number of confirmed cases in COVID-19 outside China has increased by 13 times, and the number of affected countries and regions has increased by 2 times; At present, there are more than 125,000 confirmed cases and more than 5,000 deaths in more than 120 countries and regions. In the next few weeks, it is expected that the number of confirmed cases, deaths and the number of affected countries and regions will further increase.

　　In addition to the epidemic itself, the current lack of prevention and control in some countries has made the international community more worried. Tedros Adhanom Ghebreyesus said on March 10th that the number of confirmed cases in COVID-19 in China has obviously decreased recently, the situation of China epidemic has been reversed, and the virus is retreating. WHO has repeatedly called on the international community to make full use of the "window of opportunity" won by China to curb the spread of the virus as soon as possible, but some countries have not grasped this window well.

　　The pandemic sounded the alarm.

　　According to WHO’s daily epidemic report, as of 10: 00 central European time (17: 00 Beijing time) on March 12, the number of confirmed cases in COVID-19 outside China increased by 6,703 compared with the previous day, reaching 44,067; The number of deaths increased by 310 compared with the previous day, reaching 1440.

　　The global epidemic situation is grim, and the alarm is "loud and clear". The cumulative number of confirmed cases in European countries exceeded 30,000, and confirmed cases occurred in 27 countries of the European Union, among which the number of Italian infected people exceeded 15,000, and the cumulative number of deaths exceeded 1,000. Italian Prime Minister Conte announced on the evening of March 9, local time: starting from March 10, Italy will implement a nationwide city closure ban, and asked all commercial activities in Italy to stop except pharmacies and supermarkets that supply daily necessities. The number of infected people in France, Spain and Germany has also risen rapidly. As of March 12, the total number of confirmed cases in the three countries has exceeded 8,000.

　　"No EU country has responded to the Commission’s appeal. This does not bode well for European unity. " On March 10th, Mauricio Massari, Italian ambassador to the EU, published a signed article criticizing the EU and its member States for their slow assistance. "The Covid-19 crisis is not just a matter for a certain country, it is a ‘ European crisis ’ 。”

　　After it was revealed by the media last week that German customs intercepted a batch of masks in Switzerland, Germany once again seized a batch of gloves that should have been shipped to Switzerland this week. The situation that the EU member states are fighting each other will undoubtedly increase the difficulty of fighting the epidemic. On the evening of March 10th, local time, the heads of state of EU member states held a video conference to reflect on the current situation of ineffective response to the epidemic and discuss the next steps, and identified four urgent tasks, including limiting the spread of the virus and ensuring the supply of medical equipment, and set up an investment fund with a total amount of 25 billion euros to fight the epidemic.

　　In the United States, located on the other side of the Atlantic, the epidemic situation is also not optimistic. On March 12th, the three major stock indexes of new york stock market plunged at the opening of the day, with a drop of more than 7%. The plunge caused the US stock market to trigger the fuse mechanism again and suspend trading for 15 minutes. The soaring number of confirmed cases and the "avalanche" in the capital market are disintegrating the previous optimism in the United States.

　　On March 11, US President Trump delivered a national speech, announcing the US-Europe travel ban and canceling the campaign to be held in Colorado and Nevada. At the same time, the panic and dissatisfaction in American society are growing day by day, and the criticism of the government’s inaction in dealing with the epidemic is one after another. Robert redfield, director of the US Centers for Disease Control and Prevention, said at a congressional hearing on March 10th that some parts of the United States have missed the window of opportunity to contain the epidemic. When asked by Congressman Harley Rhoda that "some people in the United States may have died of flu on the surface, but in fact they may have died in COVID-19", redfield confirmed the above situation for the first time.

　　The epidemic situation in the Middle East continues to spread. More than 10,000 cases have been diagnosed in Iran, the "hardest hit area", and many political figures have been recruited one after another, including two vice presidents. On March 11th, the epidemic situation in Qatar, which faces Iran across the sea, took a turn for the worse, announcing a sudden increase of 238 confirmed cases in a single day, increasing the number of confirmed cases from more than 20 to 263, making it the country with the largest number of confirmed cases in the Middle East except Iran. The number of new cases in South Korea and Japan began to decline, and the prevention and control measures have achieved initial results, but they have not been completely contained. According to the report of the Central Epidemic Prevention Countermeasures Headquarters of South Korea, as of 0: 00 local time on March 13th, South Korea has added 110 confirmed cases in the past 24 hours, with a total of 7979 confirmed cases. As of 10: 30 local time on March 13th, the number of confirmed cases in COVID-19 in Japan has increased to 690, and there are 697 confirmed cases on the cruise ship "Diamond Princess" docked in Yokohama, Japan.

　　This time, COVID-19 is the first coronavirus infectious disease known as pandemic in history. In 1965, British scientist Terry discovered coronavirus in the experiment of 20,000 volunteers voluntarily catching cold, and this virus is the chief culprit of a series of infectious diseases such as influenza. At present, seven kinds of pathogenic coronaviruses have been found in human beings, including SARS in 2003, which was transmitted to humans by the atypical pneumonia virus carried by bats through the intermediate host civet cats; In 2012, the Middle East Respiratory Syndrome (MERS) coronavirus was hosted by camels, and it was brought back to South Korea by a Korean after the outbreak in the Middle East, causing large-scale spread. At the end of 2019, the coronavirus once again came to the fore.

　　However, while the world is concentrating on fighting the COVID-19 epidemic, some countries are still neglecting to respond, and even busy "throwing the pot" to blame, attacking and discrediting, failing to make effective use of precious window time, which is also one of the reasons why the global epidemic has become more severe. Faced with the virus threat full of unknowns and changes, Tedros Adhanom Ghebreyesus has repeatedly stressed that all countries "need facts, not fears", "need science, not rumors" and "need unity, not stigma".

　　How does the world respond?

　　"People have never paid so much attention to a word (pandemic). Let me give you some more important and feasible words: prevention, preparedness, public health, political leadership, and most importantly, people. " WHO said that calling this epidemic a pandemic will not change what WHO is doing or what countries should do.

　　WHO summarizes the overall strategy that countries must adopt to prevent infection, save lives and minimize the impact into four main points: preparation, response at any time, detection, protection and treatment, reduction of transmission, and innovation and learning. According to the "Prevention and Response to Pandemic Influenza" previously published by WHO, if the epidemic enters the pandemic stage, WHO and governments should take a series of countermeasures, including strengthening cooperation between national health institutions and international organizations, sharing information, providing humanitarian assistance to countries with insufficient medical resources, accelerating vaccine research and development and approval of antiviral drugs, taking measures to reduce or suspend activities that cause public gathering, and issuing travel warnings.

　　Describing COVID-19 epidemic with pandemic does not mean that the epidemic is out of control. On the contrary, thanks to strict and proven measures taken by some countries, including China, WHO says that countries can not only change the course of COVID-19 pandemic, but it will be the first controllable pandemic in history.

　　"This epidemic has made us deeply realize that the world is a whole, and countries depend on each other and only sweep ‘ Snow in front of your house ’ It won’t work. " Professor Jin Canrong, deputy dean of the School of International Studies at Renmin University of China, said in an interview that the international community must jointly prevent and control the epidemic, strengthen mutual assistance and cooperation in scientific research, epidemic monitoring, information sharing and medical assistance, and build a community of destiny to fight the epidemic.

　　In this regard, China has put it into action. At 22: 31 local time on March 12th (at 5: 31 Beijing time on the 13th), a 9-member expert group formed by the National Health and Wellness Commission and the China Red Cross flew from Shanghai to fiumicino Airport in Rome with 31 tons of medical supplies, after more than 10 hours’ flight, to support the prevention and control of the epidemic in COVID-19. This is the third team of medical experts sent by China after supporting Iran and Iraq.

　　After the outbreak, China released information openly and transparently, took the initiative to share the virus gene sequence with other countries in time, and gained valuable time for the international community to fight the epidemic through strong prevention and control measures; When the epidemic situation showed a positive trend and the prevention and control measures achieved good results, China sent anti-epidemic expert groups to Iran, Iraq and Italy, and provided anti-epidemic materials such as masks, medicines and protective clothing to Japan and South Korea. The government of China has also donated 20 million US dollars to the World Health Organization to export much-needed medical materials and equipment to some countries, and local governments and non-governmental organizations have also lent a helping hand to other countries.

　　Countries take corresponding prevention and control measures according to their national conditions, and the "China experience" can help countries to take less detours. Bruce Aylward, the foreign leader of the China-WHO joint expert inspection team in COVID-19, said that China is currently the country with the most experience and achievements in dealing with the COVID-19 epidemic in the world; China’s anti-epidemic methods can be replicated. With China’s experience, other countries don’t have to start from scratch.

　　On March 12th, the National Health and Wellness Commission and the World Health Organization jointly held an international briefing on sharing the experience of preventing and treating China in COVID-19 by multi-site video link. Ma Xiaowei, director of National Health Commission, shared China’s anti-epidemic experience from eight aspects, saying that "China’s prevention and control strategies, methods, technologies, standards and cases have stood the actual test and are willing to share them with the international community to help maintain global health and safety". On the same day, in the First Affiliated Hospital of Guangzhou Medical University, Academician Zhong Nanshan and the intensive care team of the hospital had a multi-party video connection with experts from Harvard Medical School and intensive care in the United States to discuss cooperation on clinical research in COVID-19.

　　Eighty-five years ago, Hans Zinser, an American epidemiologist, warned in his classic book Mice, Lices and History: A New History of Human Destiny that no matter how safe and orderly modern civilized life seems, bacteria, protozoa and viruses always lurk in the shadows. As long as people let their guard down, they will attack.

　　There are 800 million viruses in every square meter of space on the earth. Whether in the past, present or future, it is the common goal of all mankind to recognize and defeat viruses. At present, the "patient zero" in COVID-19 has not been found, and there are still many unknowns about the origin, spread and evolution of Covid-19, which need to be answered by researchers from all over the world.

　　"The virus has no borders, and the unity and cooperation shown by people, medical personnel and researchers in various countries in the face of the epidemic shows that the concept of a community of human destiny has been deeply rooted in the hearts of the people." Pierre piccard, a professor at the University of Paris VIII, said.

　　Under the epidemic situation, all countries share the same fate, and only by watching and helping each other can we overcome the difficulties together. As the Supreme Leader General Secretary pointed out in his reply to Bill Gates: "I have always said that human beings are a community of destiny. Unity and cooperation are the most powerful weapons to overcome epidemics that affect the safety of people in all countries. "

　　The film Chinese Doctors made its first public release in Wuhan, the "City of Heroes" — — On July 4th, the film held a grand premiere in Wuhan Hongshan Auditorium, which was the first time that starring Zhang Hanyu watched the film on the big screen. He was nervous and uneasy before the screening, because Zhang Dingyu, the prototype he played and the former president of Jinyintan Hospital, was sitting next to him. After the movie, Dean Zhang Dingyu said "thank you" to Zhang Hanyu, which made "tough guy" Zhang Hanyu burst into tears instantly.

　　Chinese Doctors was released on July 9th, and its box office has exceeded 300 million. After The Captain, Zhang Hanyu once again played the role of people’s hero in Chinese Doctors. Zhang Hanyu was glad that he and Dean Zhang Dingyu had a fate: "We were both born in December 1963, and I was three days older than him. During the epidemic, I saw the deeds of Dean Zhang Dingyu and was moved by him. As a result, the film actually found me to play him, which is really a great honor. "

　　preparatory work/be about to work

　　I went to Jinyintan Hospital the next day.

　　In order to shape Dean Zhang Dingyu, Zhang Hanyu has done a lot of preparatory work. The first thing is to observe the work and life of Dean Zhang. When Zhang Dingyu came to Beijing for a meeting, Zhang Hanyu met the Dean and had an intuitive initial impression. Chinese Doctors was turned on on October 1, 2020, and Zhang Hanyu went to Wuhan Jinyintan Hospital the next day and lived with Dean Zhang Dingyu for several days. "Jinyintan Hospital is an infectious disease hospital. We will go to wards such as AIDS and tuberculosis with Dean Zhang Dingyu. Dean Zhang walked a lot of wards from 9: 00 a.m. to 12: 00 a.m. that day, and his work was very meticulous, which reflected some work that a practical dean should do, and I captured it, which played a great role in my later role. "

　　Dean Zhang is suffering from frostbite. However, Zhang Hanyu said that he deliberately took it back during the performance, without too much emphasis on the inconvenience of his legs: "I think it’s enough to catch a general state of him, and there is no need to enlarge it. Dean Zhang is a very strong man. I have been in contact with him for a few days, and I feel that he has the personality of Wuhan people and is very straightforward. Although his legs are inconvenient and he knows that he has gradual freezing, he is still optimistic and upward. He wants to do a good job in Jinyintan Hospital, and he wants to take people from this hospital with him. He is a real tough guy, a dean with a tough appearance and a strong heart. "

　　True reduction

　　Scene 1:1 Building

　　Professional medical workers give guidance.

　　Since its release, Chinese Doctors has been recognized by the medical staff who participated in the fight against the epidemic, and praised the true restoration and details of the film. Ran Xiao, the film consultant and deputy director of the Department of Emergency and Critical Care Medicine of tongji hospital Sino-French New Town affiliated to Tongji Medical College of Huazhong University of Science and Technology, who has personally fought against the COVID-19 epidemic, also praised the film for contributing to a "textbook-level medical drama".

　　Zhang Hanyu said that truth is the goal pursued by the master, and all the scenes in the film, such as ICU ward, hospital corridor and hall, were built in strict accordance with the hospital standard of 1:1. All medical equipment such as ventilators and defibrillators are real. "We have dozens of professional medical workers to guide and grasp the professionalism of medical care. This is a very professional film and can’t be fooled, so the requirements in this respect are relatively high. "

　　Compared with other actors who wear protective clothing all day, Zhang Hanyu said that he doesn’t wear much, because the dean has to be busy with things outside. "I have worn it several times, and the time is not particularly long, sometimes half a day. As long as you wear it for half an hour or an hour, your face will be covered with marks. I thought, it is really not easy for these real doctors and nurses to wear them for seven or eight hours a day. "

　　Role reproduction

　　Not in front of Dean Zhang Dingyu, make a fool of oneself.

　　Zhang Hanyu said that Chinese Doctors is a realistic film with Dean Zhang Dingyu beside him. When filming in Jinyintan Hospital, the dean came to visit our class. If you are not real in it, and what you said is not what Dean Zhang would say, it would be too make a fool of oneself and embarrassing. "So, the lines are basically not memorized, and many of them are added temporarily by me. Grasp the basic speaking speed of the resident, so I feel closer to the dean. "

　　Zhang Hanyu thinks that it is very important for directors, screenwriters and actors to "believe" whether a role is successful or not. "You have to believe 100%. If you are skeptical, you don’t believe in it at all, or you don’t seem to care about it, then you can’t write the play, you can’t play it well, and you can’t shoot it well, that’s for sure."

　　What makes Zhang Hanyu passionate about performing is that he was moved by the story of Dean Zhang Dingyu before he took over the performance. "I am particularly moved, especially convinced, and I can understand the feelings of Dean Zhang Dingyu as a patient with gradual freezing. He is eager to do more things in the limited time that he can live like a normal person, and he really fulfills this. He is actually the dean of a very ordinary small hospital. He is an ordinary person who can no longer be ordinary. But what he does is not a slogan. He is fulfilling the duties that a communist party member should perform and a responsible dean. "

　　Take the initiative to play in Chinese Doctors’s protective clothing is a battle suit.

　　Yolanda said: "How to play a play that only shows the eyes?"

　　In the movie Chinese Doctors being shown, Yolanda’s performance is quite recognized. She seems to be playing a female general, merciful and firm, caring for a pure land and fighting death. And Yolanda also said that when she played Wen Ting, director of the Department of Critical Care Medicine, it was as if she was on the battlefield, and protective clothing was her battle suit. When she put it on, she could quickly enter the state.

　　Before seeing Chinese Doctors’s script, Yolanda decided to star in this film. "I think this is a play that can’t be rejected. Its value exceeds the film itself, so I took the initiative to fight."

　　After filming this film, Yolanda was deeply touched. She felt that the medical staff’s rescue of the wounded and dying in reality required both high-difficulty professionalism and strong inner belief. As an actor, she could only try her best to approach this realm, but she could not reach it. Therefore, what she wants to say most after filming this play is: "Medical workers are really great."

　　The characters represented the backbone of the whole medical field.

　　Yolanda thinks that Wen Ting, director of the Department of Critical Care Medicine, represents the backbone of the whole medical field. "They have psychological qualities that ordinary people don’t have. This is what I have always wanted to experience in the whole film shooting, and I feel that it is far from perfect. They have the calmness and calmness when they are in danger, and they have accumulated professional experience and judgment for many years. They don’t bring personal emotions to work, as long as they wear white coats, it is a professional state. In this movie, they occasionally have a little emotional expression, which is also very real. "

　　In order to ensure the professionalism of the film, the Chinese Doctors crew invited a number of medical consultants. When meeting them for the first time, Yolanda said that these doctors and nurses have a particularly firm strength and are particularly optimistic. "We asked them how they experienced it at that time, and their answer was particularly simple, saying ‘ I just carried it ’ . You believe in the power of professionalism, and then try your best to arrange and care for every patient you receive. At that time, you can’t think of anything else in your mind. This is professionalism. "

　　The more you invest, the more you admire the stability of medical staff.

　　Regarding the belief held by medical workers, Yolanda admits that he didn’t find it until the end of filming: "Chinese Doctors is probably the most uncertain work I have ever filmed, and every time I shoot a scene, I feel a little trance. The more you know about the feeling, the more you can feel that it is uncontrollable. Some medical drama shows that doctors can accurately grasp the patient’s condition and save lives, which will make you feel that the medical staff are very handsome. However, in the process of filming this play, I feel that every step they take is on thin ice, and their handsome appearance is a very professional presentation. I have been trying to get close to this state throughout the play, but it is too difficult. "

　　Yolanda revealed, "The epidemic situation is a completely sudden situation for most medical staff. Every operation they face, every patient, is calm after inner chaos. "

　　Yolanda tried to find a sense of stability in the uncontrollable panic, and the more she devoted herself to it, the more she admired the stability of medical staff. "A mature medical staff, after more than ten years or decades of professional study and years of clinical experience, really can’t be mastered by an actor in a few months or six months. From The Captain to Chinese Doctors, my feeling is that you will feel that every profession is sacred and it is difficult to enter in a short time. It takes others to spend most of his life to achieve his achievements and position in this profession, and it takes a long time to accumulate. Therefore, now I am awed when I go anywhere to see people from different professions. This may be a particularly rare experience as an actor. "

　　Protective clothing is the "channel" for entering the show.

　　Yolanda spent a lot of time wearing protective clothing in the film. She said that she didn’t count how long she wore it every day. "Every day, she put it on when shooting, and she can’t take it off during the break because she has to wait. Sometimes I don’t want to change clothes when I am at rest, because it is comfortable to change clothes. If you feel comfortable, you may feel wrong, so you will continue to wear it. "

　　For Yolanda, protective clothing is the "channel" for her to enter the play. When she wears it, she will have the state of the play: "I don’t feel anything, because it’s like a war. That’s why I feel like I’m close to a real doctor every time I shoot a surgical scene. Because it’s like going to war in a shirt. We are the same when shooting, often with a long lens. "

　　When she entered that state, Yolanda said that she couldn’t feel fatigue or other emotions. There was something wrong with the ligament of Yolanda’s leg itself. She didn’t feel pain at all when filming, but she felt better. However, after filming one morning and taking an hour off, the pain came back. So, Yolanda felt that doctors at that time were the same. They wouldn’t have time and energy to pay attention to themselves, and the fatigue seemed to disappear.

　　She revealed: "There are really doctors who haven’t closed their eyes for 36 hours, that is, one case after another. What kind of physical strength and energy do you think it needs?" Therefore, if you wear protective clothing for 8 hours, you will certainly feel tired, so the director shouted ‘ Stop ’ Sometimes, you will feel as if you might need a fulcrum to catch your breath. But say ‘ Come again ’ When shooting, I forgot it in an instant. I think it was the same when they went to save patients in clinic. There is a feeling of being desperate. "

　　Yolanda’s proficiency in wearing protective clothing was praised by everyone, but she said that she could not reach the professional level. "Their speed is fast, because when taking off protective clothing, you should avoid the contaminated surface and pay great attention to those details. We’re actually not that skilled. Moreover, our filming will not be as thorough as the real situation, because it is too troublesome. Every time we complete a step, we must do a hand disinfection. "

　　tell about

　　"Control your eyes, just hold your horses."

　　The actors in Chinese Doctors only show their eyes most of the time and can only use their eyes to convey their emotions. Other actors in the crew say that Yolanda is the least difficult because her eyes are all drama.

　　Yuan Quanxiao said that it may be an advantage for others to have big eyes, but in her own view, it is necessary to control more and control emotions. "Because in the profession of doctors, sometimes your personal emotions cannot be revealed too much. For me, this anti-control is actually a difficult problem. Control your eyes and let them try not to reveal their emotions. "

　　How to do it without revealing emotions? Yolanda said that his way is to always tell himself not to panic. "But it is impossible to panic, so I have been telling myself in this play: just hold your horses and don’t panic."

　　From the first day of joining the group, Yolanda let himself put aside all the so-called acting experience in the past, because Chinese Doctors told what really happened. "What we saw in the hospital was not performative. It doesn’t need you to be radiant anytime and anywhere, because the focus is not here. Especially in the epidemic, people may experience more anxiety, fatigue, despair and collapse caused by physical overdraft, and then rebuild their confidence. "

　　Yolanda thought the performance felt like a tree. "The surface of the tree is rough, which will make your hands wear out, but its roots are deep. Therefore, I feel that I don’t want to make up in details, and my hair can’t be too neat, because Director Wen Ting has no time, and her energy is all about saving people. "

　　Always wearing a mask, with a lot of marks on his face, wearing protective clothing for a long time, and sometimes taking an operation and getting soaked, this state makes Yolanda feel that he is entering the role: "Compared with the medical staff who really fight the epidemic, you certainly can’t reach their state, but you also seem to feel that when you are exhausted, you seem to be a little closer to them. In this play, any sense of comfort does not match the role. " This edition/reporter Xiao Yang co-ordinates/Man Yi

　　　　　　 CCTV News:Now, almost every household has broadband. Broadband is idle when we are not at home. If someone told you that these flows can be realized by renting out profits, would you be moved? Some time ago, Mr. Liu, a citizen of Yichang, Hubei Province, was moved by this way of making money, and it turned out that it was a scam.

　　　　　　 Some time ago, Mr. Liu from Yichang, Hubei was introduced, saying that if you rent the idle broadband traffic at home, you can get high cash back, but only if you rent the port of an APP first. So Mr. Liu invested 20 thousand yuan first.

　　　　　　 Victim Mr. Liu: "The rent of a node is 400 yuan a month, and then it can generate 20 yuan a day, which is 600 yuan a month, and you can earn 200 yuan by investing 400 yuan. Twenty thousand dollars bought fifty mouths, and then the twenty thousand dollars returned thousands of dollars. "

　　　　　　 After seeing the profit, Mr. Liu added investment again, but this time the cash back was delayed. He felt cheated and went to the police station to call the police. After receiving the police, the police immediately launched an investigation and found that this was a typical investment fraud case.

　　　　　　 Yang Zhou, a policeman from Xiling District Bureau of Yichang Public Security Bureau: "In the process of fraud, they actually pay back the money to the victims of the previous investment in proportion on a regular basis as promised, but they are actually waiting for an opportunity, that is, once there is a victim who invests a large amount at one time, the fish is hooked, and they will no longer pay back."

　　　　　　 According to the clues provided by the victim, the police locked three suspects in Anyang, Henan Province and arrested them. At the scene, 22 mobile phones, 31 phone cards and 1 computer involved were seized, and 240,000 yuan was recovered.

　　　　　　 After investigation, three suspects forged a set of apps with realized traffic and posted advertisements through multiple channels to attract victims’ investment.

　　　　　　 Zhang Junrui, a policeman from Xiling District Branch of Yichang Public Security Bureau, said: "This kind of network port (fraud) case is relatively new, and the fooled groups are all over the country."

　　　　　　 At present, three suspects have been criminally detained, and the number of deceived people and the amount involved are being further processed.

　　CCTV News: Tissue paper and toilet paper, collectively referred to as household paper, are one of the just-needed products for living at home now. In fact, just 30 or 40 years ago, these professional household papers, especially tissue papers, were still high-end goods and rare goods in our lives. Of course, now that everyone has a good life, professional household paper has become a necessity of life, but a supervision and spot check by the relevant departments found that some household paper actually has a low level of hygiene.

　　Jiangsu Provincial Bureau of Quality Supervision recently conducted supervision and spot checks on tissue paper and toilet paper products. The results show that some tissue paper is produced with recycled raw materials, and some toilet paper is "unsanitary" and many other unqualified problems.

　　Li Xiaotong, inspector of Jiangsu Paper Printing Products Quality Inspection Station, said that there were 162 batches of samples of tissue paper and toilet paper in this supervision and spot check, including 99 batches sampled by production enterprises, 18 batches purchased by physical stores and 45 batches purchased by e-commerce platforms. All samples involved 112 brands of 101 production enterprises.

　　In this supervision and spot check, Jiangsu Quality Supervision Bureau entrusted Jiangsu Paper Printing Product Quality Inspection Station and Huai ‘an Quality Inspection Institute to conduct testing. Among the 162 batches of samples, there were 88 batches of tissue paper and 74 batches of toilet paper.

　　In the interview, the reporter noticed that in this supervision and spot check, the unqualified rate of tissue paper was much higher than that of toilet paper. Among the 35 batches of unqualified samples, 28 batches of tissue paper were used.

　　The content of tissue paper is a quantitative information that the manufacturer clearly shows consumers how many sheets of paper are contained in this package of tissue paper on the outer packaging of the enterprise. However, in this supervision and spot check, it was found that 13 batches of tissue paper were unqualified, which is what we usually call short weight and short weight. As you can see, there are 500 sheets of tissue paper labeled as Yiran brand in my hand, but after testing, there are only 132 sheets of tissue paper in this package, which is only about a quarter of the express value.

　　After testing, among 28 batches of unqualified tissue paper samples, there are 13 batches with insufficient internal capacity, which is the biggest problem found in this supervision and spot check.

　　Of the 13 batches of unqualified samples, 8 batches were sampled from production enterprises, including:Named "Meijiaxin" extraction embossed napkin produced by Nanjing Bairun Paper Co., Ltd.; Named as "Weiyi (Cocoa Elephant Series)" extraction paper towel produced by Nanjing Yuankuo Technology Industry Co., Ltd.; Known as "Yinsijie" natural bamboo pulp paper produced by Zhenjiang Minzhen Paper Co., Ltd.; Known as "Shunan" removable facial tissue produced by Zhenjiang Sunan Trading Co., Ltd.; Known as "Haoxiang" bamboo fiber tissue produced by Zhenjiang Haoxiang Paper Co., Ltd.; Known as "Qianfeng" handkerchief paper produced by Changzhou Yudi Paper Co., Ltd.; Named as "Jieshilian" removable facial tissue produced by Baofuda Sanitary Products Factory in Shang Hu Town, Changshu City; Known as Xuzhou Tianqiang Paper Co., Ltd. produced "Xuanzhu" removable facial tissue.

　　4 batches are purchased from physical stores, including nominal sentences."Merlot" extracted facial tissue produced by Rongshi Jingwang Paper Factory; Known as "Yiran" removable facial tissue produced by Jiangsu Yangzhou Yiran Paper Co., Ltd.; Named "Fang Yaxin" produced by Jinsheng Sanitary Paper Factory in Jiangning District, Nanjing, with 420 pieces of removable facial tissues in gold; Named "Yufeng" removable tissue paper produced by Nanjing Yufeng Paper Processing Factory.

　　1 batch purchased from e-commerce, nominallyExtractable facial tissue produced by Senli Paper Group Co., Ltd..

　　In addition to the lack of internal capacity, this test found that the second major problem of tissue paper is that manufacturers illegally use recycled fibers as raw materials.

　　According to the inspectors, the national standard for tissue paper stipulates that recycled fibers are not allowed, and native wood fibers or non-wood fibers must be used. The national standard of toilet paper allows the use of native wood fiber, non-wood fiber and waste paper fiber. Wood fiber refers to primary wood pulp, non-wood fiber includes rice straw, straw, bamboo and sugarcane pulp, and recycled fiber is waste paper pulp.

　　The inspector told the reporter that the color of tissue paper produced by primary wood pulp is white, while the color of tissue paper produced by recycled fiber is gray and dark. At the same time, there are usually residual ink spots on its surface.

　　After testing, it is called a sentence"Merlot" extracted facial tissue produced by Rongshi Jingwang Paper Factory; Named "Yufeng" extraction tissue paper produced by Nanjing Yufeng Paper Processing Factory; Named as "Jielian" removable tissue paper produced by Suzhou Weirou Paper Co., Ltd. in Jiangsu Province.All three batches of tissue paper samples were found to contain migrating fluorescent whitening agents, and their dust levels were also unqualified. Consumer use

　　Such a tissue paper wipes the mouth, and the mobile fluorescent whitening agent may be absorbed by the human body, causing hidden dangers to the health of consumers.

　　NominallyThe "Pinrui" luxury handkerchief paper produced by Chengdu Jinxiangcheng Paper Co., Ltd. is marked with product grades outside the national standard at will. At the same time, some samples, such as "Yinsijie" paper handkerchiefs produced by Zhenjiang Minzhen Paper Co., Ltd., have the phenomenon that manufacturers falsely mark product grades.

　　During the inspection of toilet paper in this supervision and spot check, it was found that the total number of bacterial colonies in 5 batches exceeded the standard, and the samples with the worst hygiene index exceeded the national standard by more than 4 times. According to the inspectors, the total number of bacterial colonies is unqualified, which means that the toilet paper is "unsanitary".

　　The unqualified samples of this index include: nominal"Friends of the Skin Wrinkled Toilet Paper" and "Jinbaide Advanced Wrinkled Toilet Paper" produced by Hongze Jinbaide Paper Co., Ltd.; Marked as "Nantong Haian Baihui Paper Factory", it is called "Shuang Dian Gao Jian Toilet Paper"; "Double Panda brand toilet paper" produced by Quzhou Double Panda Paper Co., Ltd.; Flat toilet paper produced by Shanghai Jiedu Paper Co., Ltd. Wait.

　　The test found that these five batches of samples with unqualified hygiene indicators were all flat-cut toilet paper produced from recycled raw materials.
