It is understood that there is a saying in the communication industry that "Gigabit is easy to enter the house, but 100 Mbps is difficult to enter the house", which means that although Gigabit broadband fttp has been realized, the WiFi signal in some areas of the house is weak due to unreasonable router placement, wall blocking signals and other reasons, which affects the online experience, and some users even mistakenly think that there is a problem with broadband quality. In order to solve the "last ten meters" network perception bottleneck of gigabit home, Guangdong Mobile and Huawei jointly launched FTTR all-optical WiFi networking service, which was launched commercially in Shantou in September 2020, and promoted the upgrade of "fttp" to "fiber-to-room". Up to now, more than 150,000 mobile broadband users in the province have used this service.

According to the relevant person in charge of Guangdong Mobile, the all-optical networking adopts the "1-N mode", that is, one optical gateway plus n optical routes, and each room is equipped with an optical route, and each optical route is directly connected with the optical fiber, truly realizing the whole house WiFi without dead ends. With the help of WiFi seamless roaming technology, when users go to different rooms, the network automatically switches without feeling. The peak download rate of 2000M broadband can reach 250MB/s, and a high-definition movie can be downloaded in ten seconds. Multi-terminals can watch 4K/8K ultra-high-definition videos online, play large-scale online games and even VR/AR games at the same time, and there will be no jam.

"With the support of ultra-high-speed broadband, new applications such as cloud computers and cloud games will develop rapidly." The relevant person in charge said that the cloud computer has no hardware such as CPU, memory and hard disk. Compared with purchasing a physical computer, the cost is lower, and users can access the data stored in the cloud and use various applications by accessing the network. Cloud games put operations, rendering, storage and other links in the cloud server, and the game screen is transmitted to the local screen in real time. With the ultra-high-speed broadband guarantee, large-scale games can be played smoothly with low-configuration terminals.

In addition, the 2000M+FTTR all-optical WiFi networking supports the parallel access of more than 200 smart devices, which not only meets the Internet demand of computers, tablets and mobile phones, but also provides sufficient space for the increasing access of smart home appliances, smart security, smart pension and other devices in the digital home scene.

It is reported that Guangdong Mobile is making efforts to build a professional team of intelligent engineers to provide users with convenient and efficient networking services. For users who choose FTTR all-optical WiFi networking, engineers come to the door to tailor the solution according to the actual situation, such as laying invisible optical fibers to the room, and will make every effort to install and repair the same day.

While vigorously promoting the upgrade of home broadband, Guangdong Mobile has also launched Zhenzhi e enterprise networking service for small and medium-sized enterprises to support thousands of businesses to improve quality and efficiency. FTTR-B networking services include professional engineers’ door-to-door, networking scheme design, personalized application customization, WiFi coverage optimization, intranet rectification and optimization, integrated wiring construction, equipment installation and debugging, network inspection and operation, worry-free after-sales and other whole-process integrated services, covering an area of 3,000 square meters, providing applications such as Gigabit broadband, Gigabit WiFi and cloud computers for small and medium-sized enterprises, and deeply meeting the needs of corporate office and cloud access.

　　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.

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.

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.

　　"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: 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.

Some time ago, I drove the car Geely Xingrui. Today, I took the time to talk about the use of this car.

It has been some time since Geely Xingrui went public, during which I also attended a launch conference of Geely Xingrui Space-Time Edition. I didn’t have a chance to test drive because it was just a listing conference.

However, as the old saying goes, "A good meal is not afraid of being late." After half a year, I still got on this car.

---

I believe that people who often pay attention to cars should be familiar with this car, so let’s go straight to the point and talk about some of my driving feelings about it.

Of course, if there are some friends who don’t know about this car, don’t worry. Later, when I talk about driving, I will also talk about other aspects of this car.

The first is power. Geely Xingrui is the only car with a 2.0T engine at the same level and price. This engine can produce 190Ps and 300N·m in generate. This power output is relatively large at the same level. For example, the horsepower output of the well-known Civic 1.5T engine is 182Ps.

So what exactly does Xingrui drive? Let’s just say that it can definitely enter the top three in terms of acceleration, and the somatosensory feeling should be within 8 seconds. But if you say how fast this acceleration is, it won’t be, just that it is a fast car in the same class. Then daily driving is definitely enough, and there is no pressure to overtake in parallel.

The matching of engine and transformer is well done, there is no sense of frustration at low speed, and the shift smoothness is ok. Driving slowly every day, the gearbox is still very obedient.

Next, let’s talk about its space. I sit in the back row with my height and weight. In fact, I don’t feel how spacious the back row space of Xingrui is. Compared with other models in the same class, it is almost the same level, such as LaVida, Sagitar, Bora, Corolla, Sylphy and so on.

The luxury of the interior design is better than the above models, and the size of the central control panel, the color matching of the center console and the skin materials are also better than the above models.

However, the shape of its gear handle does not match the overall interior style, and a simple yacht gear handle stands abruptly on the center console. Switching to a button-type or knob-type shifting mechanism should improve the look and feel.

In terms of sound insulation, the engine roar will be more obvious at medium and high speeds. However, this is normal, and even joint-venture B-class cars at the same price will also have this phenomenon. The isolation of tire noise and wind noise is good, and the engine vibration control is also very good.

The chassis has a certain texture. After some ups and downs, the road surface has a good vibration filtering effect, and the vibration transmitted to the steering wheel is also very small. Under the condition of slow driving, the advanced feeling is still satisfied.

Finally, let’s talk about energy consumption. This 2.0T engine needs to be filled with No.95 gasoline. The total fuel consumption level is basically no advantage at the same level and price. The comprehensive fuel consumption of NEDC is 6.7L/100KM.

In terms of selling price, the price range of Geely Xingrui is 11.37-15.27 million, which is almost consistent with the mainstream joint venture brand A-class cars, such as the common Corolla, Sylphy and LaVida. By looking at its sales volume, it is found that Geely Xingrui can sell tens of thousands of units a month, which shows that the launch of this car is successful and it is not afraid of the status of the joint venture brand.

---

As the saying goes, "No second in martial arts and no first in literature", at the test drive site, the activist also arranged a competing car for Xing Ruian, which is sagitar from the Volkswagen brand.

Driving two cars back and forth on the same route, sagitar has advantages in shifting speed and fuel consumption compared with Xingrui, especially in the case of fuel consumption. When sagitar speed is more than 30 kilometers per hour, the gearbox has risen to the fourth gear, which is not only fast but also very positive.

However, it may be due to the low basic displacement. When the sagitar is at a low speed (about 1350 rpm), the engine jitter will be transmitted to the steering wheel and seat, so the comfort and advanced feeling are relatively poor. The guess is that the factory engineer deliberately calibrated it in order to save more fuel.

However, for users who buy this car, this little bit of jitter has little effect on them. After all, fuel saving is king, especially in the current high oil price environment.

Sagitar has advantages in the above two aspects, but it is not as good as Xingrui in other aspects, such as advanced driving sense, advanced interior sense, steering feel and so on.

To tell the truth, I still drive a few mainstream or non-mainstream A-class cars in China, so I can’t figure out how competitive Geely Xingrui is. But from the two cars I have tested, Geely Xingrui is superior to Sagitar in many aspects.

But if you ask me to make a choice between these two cars, I will choose sagitar. The reason is very simple. I will buy a car of this grade in terms of its durability, fuel economy, brand and space. And sagitar can satisfy me in these aspects, especially the fact that leather is durable (of course, the early sagitar is not counted, and interested friends can search for "broken shaft door"). As a car that needs to be used frequently, reliability is more important than everything.

However, for friends who are not very sensitive to fuel consumption and have requirements on vehicle configuration, design and power, then Geely Xingrui is a good choice. (Text/Power)

　　[Pacific Auto Network] In recent years, BYD’s models mostly belong to the dynasty series, and its domineering "Dragon Face" design and car series named after the dynasty have left a deep impression. However, as one of the independent brand giants, how can BYD’s model matrix stop at the dynasty series? I believe readers who pay attention to BYD’s dynamics will remember that this year, BYD brought a quite lovely — — dolphin Dolphins, on the other hand, belong to a refreshing series of ocean nets.

　　BYD’s Ocean Net is a comprehensive sales network, which has more distinctive new energy attributes and is aimed at younger users. It has two product sequences, namely, a pure electric product series named after marine life and equipped with the latest technology of E platform 3.0 and a hybrid product series named after warships and equipped with DM-i super hybrid technology. The destroyer 05, which was unveiled this time, is the first car of Ocean Net and the first model of warship series.

　　As the first car of Ocean Net, destroyer 05 is equipped with a subversive DM-i super hybrid system, and has created a brand-new body posture with marine aesthetics. Recently, Xiaobian participated in the static appreciation of destroyer 05. Although the interior design of the real car has not been made public, there are also many bright spots in the modeling that are worth mentioning. Let Xiaobian take you to appreciate it carefully.

　　In recent years, BYD’s models mostly belong to the series of "Long Yan Aesthetics" design, which has won the aesthetics of many consumers in China through domineering and three-dimensional lines. As for the models coming to Ocean Net series, based on the younger target user group, destroyer 05 did not inherit the previous style, but was built with the design concept of "ocean aesthetics", which is obviously different from the "Dragon Beauty" of Dynasty series in design style.

　　According to the official statement, "marine aesthetics" is based on inheritance and innovation, so it is more inclined to carve the body posture of trend aesthetics to interpret the new energy attribute of its scientific and technological movement. Therefore, we can also see that the style of destroyer 05 is obviously different from the BYD model that we are used to seeing. In this static appreciation, the official gave the real car with blue and gray paint. When the more concise figure and the front face with full impact were covered with these two colors, it showed a different freshness from BYD in my mind.

　　I believe that everyone who sees destroyer 05 for the first time will be shocked by its exaggerated front face. This set of front face, called dot matrix borderless grille, builds the design core of destroyer 05. Its design inspiration comes from the ripples of the waves. Through the drop-shaped dot matrix and staggered decorative strips, the boundary of the traditional grille is weakened. On the basis of inheriting BYD’s traditional horizontal bar grille, its trapezoidal horizontal strips are staggered, and the visual width of the whole vehicle is further extended by combining the vertical air guides on both sides of the front.

　　The destroyer 05 adopts LED light source, and the recognizable penetrating daytime running light combined with the decorative strip above creates a wide-body, low-lying and radical visual effect; The dual-lens headlights are sharp in shape, supplemented by dot matrix design on both sides, combined with BYD’s new Logo, which further enhances the recognition and sense of technology of the front face.

　　Headlights and decorative strips parallel to logo are connected into a whole, and the transparent shell is wrapped, while all horizontal decorative strips on the front of the car, with gradient floating points, finally converge into the ultimate simple plane, which, together with the headlight group, shows a smooth and neat feeling, which is very rich in design and impact.

　　The side of the car body inherits BYD’s design language at the same level, giving it a simple and full sense of movement with the proportion of the coupe and the waistline of the ship jump and the window line outlined upwards. In terms of body size, the length, width and height are 4780/1837/1495mm and 2718mm, respectively, and the length is slightly increased compared with that of other dimensions, so the destroyer 05 is more slender visually.

　　The destroyer 05 is equipped with 17-inch front halberd wheels, with two-color multi-frame modeling and four ellipsis embellishments echoing the front face design theme. The size of the real model is 215/55R17, and the brand is Atlas AS380 series, which has a good performance in wetland control and mute.

　　There are also three slash concave lines on the exterior rearview mirror as decoration, which echoes the "dot matrix borderless grille" on the front face. The word "NFC" on it means that users can associate the online wallet App with BYD cloud service App on their mobile phones, activate the car key function, and then swipe the mobile phone in the identification area of the main driver’s rearview mirror to complete the vehicle unlocking and locking actions. There are also cameras under the rearview mirrors on both sides. Combining the front and rear cameras, we can see that the destroyer 05 will have a 360 configuration.

　　The rear of destroyer 05 echoes the front face from a distance, and the rear air guide keeps the language unified with the front face. By accurately controlling the proportional relationship, the rear vision is wider, and the layering of the rear is greatly enriched. At the same time, the towering tail outlined by the rising side waistline makes the visual effect quite compact.

　　The taillights of the new car are designed in a geometric array lattice, which is highly recognizable with the penetrating running lights echoing the front of the car. At the same time, the blackened taillights and the red penetrating running lights form a cold and warm contrast, showing the style of science and technology and exquisiteness.

　　If you look closely, you can see that the interior of the lamp group is quite three-dimensional and meticulous, and the LED lamp group similar to the dotted line is divided into two layers, which also echoes the overall design theme.

　　In terms of power, the DM-i super hybrid system carried by destroyer 05 includes: Xiaoyun-plug-in special 1.5L high-efficiency engine, EHS electric hybrid system and core components of DM-i super hybrid special power blade battery.

　　Xiaoyun-Plug-in special 1.5L high-efficiency engine is specially built for DM-i super hybrid technology, with a thermal efficiency of 43%, a peak power of 81kW/6000rpm and a peak power of 135 N m/4500 rpm, and many revolutionary changes such as 15.5 superelevation, Atkinson cycle, EGR cooling, etc. Compared with the previous generation engine, the friction loss of BYD plug-in special high-efficiency engine is reduced by 10%, the weight of the whole engine is reduced by 10 kg, the fuel consumption without charging is controlled within 4L/100km, and the emission meets the "National Six B".

　　BYD has developed to the third generation of DM technology since it first introduced the first generation of DM technology in 2008 on plug-in hybrid vehicles. First of all, the DM-i system adopts an electric hybrid structure driven by a high-power motor, with a large-capacity power battery as the main energy supply and supplemented, and the fuel consumption is only 3.8L/100km in the case of power shortage. DM-i super hybrid consists of core components such as Xiaoyun-plug-in special 1.5L engine, EHS electric hybrid system, DM-i super hybrid special blade battery and AC/DC vehicle charger.

　　The black technology in EHS electric hybrid system is the integration of double motors+double electronic control+single gear reducer+direct drive clutch+motor oil cooling system. Compared with the separate arrangement of motors and electronic control in the first generation DM technology, the volume is reduced by 30% and the weight is reduced by 30%. In terms of motor speed, the speed of EHS electric hybrid system can reach 16000rpm. Due to the increase of speed, its backup power is more sufficient and the overall driving experience is better. However, due to the increase of rotating speed, it is a great challenge to its sealing and NVH.

　　In addition, the EHS electric hybrid system is mainly driven by electricity in terms of architecture. When the power is sufficient, it has the driving experience of pure electric vehicles, and in the state of power loss, it is mainly driven by electricity, which can greatly reduce fuel consumption. In terms of driving experience, because it has many different driving modes, it can reduce the driver’s driving fatigue, which will be different from the single driving mode in extended-range vehicles.

　　In terms of battery, destroyer 05 adopts DM-i special power blade battery, which has a more efficient power output range and further improves endurance. In addition, its high safety without fear of acupuncture test and high space utilization without modular structure can bring users a different new energy driving experience.

　　This blade battery supports 3.3kW AC slow charge and 17kW DC fast charge, and also has the characteristics of high power, large capacity and low internal resistance.

　　According to Xiaobian, it is learned from the official that the price range of the destroyer 05 will be between 120,000 and 150,000, and the vehicle positioning and configuration will be higher than all the compact cars at present. With the younger design and the blessing of DM-i super hybrid technology, the destroyer 05 is quite exciting. At present, the official has not released the interior design and detailed configuration of the new car.
