　　Cctv newsOn September 27th, the Department of Science, Technology and Information Technology of the Ministry of Education issued a document "Adhering to the" Four Orientations "and Serving" the Biggest Country "— — Since the 18 th National Congress of the Communist Party of China, scientific and technological innovation in colleges and universities has served the high-quality development of the economy and society.

　　Since the 18th National Congress of the Communist Party of China, under the strong leadership of the CPC Central Committee, China has successfully entered the ranks of innovative countries and embarked on a development path from strong talents and strong science and technology to strong industry, economy and country. In this process, the Ministry of Education consistently and resolutely implements the spirit of the important instructions of the Supreme Leader General Secretary and the decision-making arrangements of the CPC Central Committee, insists on serving the country as the highest pursuit of scientific and technological work in colleges and universities, gives full play to the unique advantages of scientific and technological innovation in colleges and universities, and organizes teachers and students to adhere to the "four orientations" and serve the "country’s greatest" and constantly March into the breadth and depth of science and technology.

　　In the past ten years, the Ministry of Education has successively organized and implemented a number of major strategic actions such as "Innovation Capacity Enhancement Plan", "Independent Innovation Action in Key Areas" and "Basic Research Everest Plan" in colleges and universities, and a series of special action plans for scientific and technological innovation such as rural revitalization, Belt and Road Initiative, artificial intelligence, carbon neutrality and blockchain. Organized universities to build a number of national key laboratories and national engineering (technology) research centers, actively laid out and built cutting-edge scientific centers and integrated research platforms, and built 688 key laboratories and 448 engineering research centers of the Ministry of Education in an organized and systematic manner, forming a scientific and technological innovation system with clear levels, reasonable structure and strong support, and steadily improving the service capacity of scientific and technological innovation in universities, which provided strong support for the implementation of major national strategies and economic and social development.

　　First, strongly support the national science and technology self-reliance.

　　Self-reliance in science and technology is the foundation of national prosperity and security, and the lifeblood of science and technology must be firmly in our own hands. In the past ten years, as the first completion unit, colleges and universities have won more than 1000 national science and technology awards. In terms of quantity, colleges and universities have won more than half of the three national science and technology awards in the past decade; In terms of quality, colleges and universities have won 60% of the first prize of national natural science and 90% of the first prize of national technological invention in the past ten years, which is the main force of basic research and the source of major scientific and technological breakthroughs in China.

　　Scientific and technological innovations serve the needs of people’s livelihood and continue to "add bricks and tiles" to the people’s better life. For example, Peking University pioneered a series of new methods of genetic diagnosis before embryo implantation in the world, which solved the major reproductive health problem of "birth defects" and brought the hope of giving birth to a healthy new life to millions of families in China. Since the outbreak of the COVID-19 epidemic, the vast number of scientific researchers in colleges and universities have devoted themselves to tackling key problems in epidemic prevention and control, developed the first anti-Covid-19 antibody drug and the first anti-Covid-19 oral drug approved for marketing in China, and made outstanding contributions to the research and development of vaccines and testing products in Covid-19. The heat-resistant molecular breeding technology of wheat invented by China Agricultural University has shortened the breeding cycle by 2-3 years, improved the breeding efficiency by 20%, and promoted the new heat-resistant wheat varieties by more than 60 million mu. The cultivated series of new corn varieties such as "Nongda 778" have accumulated an area of 50 million mu, increasing production by more than 10 billion Jin and increasing farmers’ income by more than 10 billion yuan. University science and technology have made important contributions to ensuring national food security.

　　Every major breakthrough in science and technology is an important opportunity to promote new technologies and industries, open up new fields and tracks for economic development, and form new advantages in international competition. For example, the world’s first pebble bed modular high-temperature gas-cooled reactor nuclear power plant, which was designed by Tsinghua University and jointly built by China National Nuclear Corporation, China Huaneng and other central enterprises, was successfully connected to the grid in 2021, pushing China’s high-temperature gas-cooled reactor from a "sample" to a "product", making China one of the few countries in the world to master the fourth-generation nuclear energy technology. Zhu Rong landed on Mars, Beidou successfully networked, the moon was sampled for the first time, the Hong Kong-Zhuhai-Macao Bridge was completed and opened to traffic, and the C919 aircraft was delivered soon. In a series of big country projects, colleges and universities have made outstanding contributions and consciously fulfilled their mission of serving high-level science and technology for self-reliance.

　　Second, independently cultivate a large number of scientific and technological innovation talents

　　Colleges and universities are the main positions for talent training and gathering, and also an important part of the national strategic scientific and technological strength, and undertake the dual missions of scientific and technological innovation and talent training. The Ministry of Education continued to deepen the integration of science and education, strengthen scientific research and education, and the group of strategic scientists and leading talents in colleges and universities grew steadily. In the past ten years, more than 350 academicians of the two academies have been added to colleges and universities, and the proportion of newly added academicians of the two academies in the past three times has exceeded 50%. More than 1,500 winners of the National Science Fund for Distinguished Young Scholars have been added, and universities have gathered nearly 70% of the total winners of the National Science Fund for Distinguished Young Scholars. According to the survey statistics, in 2021, more than 1 million graduate students participated in the research and development projects of science, engineering, agriculture and medicine, double the number in 2012. National development depends on talents, and national rejuvenation depends on talents. In the past ten years, scientific and technological innovation in colleges and universities has strongly supported the independent training of innovative talents, provided the source of living water for the construction of national strategic talents, and accumulated important strength for high-quality economic and social development.

　　Third, vigorously promote the transfer and transformation of scientific and technological achievements

　　Only when scientific and technological achievements are transformed into real productive forces can we truly release the driving force of innovation-driven development. In the past ten years, the number of patent transfer and licensing contracts in colleges and universities has exceeded 65,000, and the amount of patent conversion has increased from 820 million yuan to 8.89 billion yuan, an increase of nearly ten times. There are two key factors that determine the effectiveness of the transformation of scientific and technological achievements. The quality of scientific and technological achievements itself is the internal cause, and policy incentives are the external cause. In recent years, the Ministry of Education, in combination with the actual situation of colleges and universities, has started from the internal and external factors. On the one hand, it has improved the quality of achievements and strengthened the source supply of scientific and technological achievements. In conjunction with China National Intellectual Property Administration, the Ministry of Science and Technology and other departments, it has studied and formulated "Several Opinions on Improving the Patent Quality of Colleges and Universities and Promoting the Transformation and Application", taking the lead in adjusting the patent subsidy incentive policy, promoting the pre-application evaluation system of patents, and reversing the bad orientation of "emphasizing quantity over quality" and "emphasizing application over implementation" of patents in colleges and universities. On the other hand, we should increase policy incentives and take various measures to promote the transformation of scientific and technological achievements. Increase the reward for the transformation of achievements and stimulate the enthusiasm of scientific researchers. At present, colleges and universities generally increase the reward ratio to 70%, and some colleges and universities reward more than 90%, accelerating the transformation of scientific and technological achievements in colleges and universities into real productive forces. For example, Sichuan University has developed and created more than 10 kinds of new narcotic drugs, of which 3 have been listed with new drug certificates and 5 have been clinically approved. Clinical research is under way, and the amount of patent conversion of new narcotic drugs has reached 837 million yuan.There are more than 60 large cutter suction dredgers, such as Tian Whale, designed by Shanghai Jiaotong University, with an annual dredging volume of over 1 billion cubic meters and an annual output value of over 10 billion RMB, realizing a historic leap from "blockade" to "export control" of key core technologies. In the past ten years, the supply quality and transformation efficiency of scientific and technological achievements in colleges and universities have been significantly improved, which has provided strong support for high-quality economic and social development.

　　Fourth, actively serve the regional innovation and development strategy

　　Colleges and universities are the talent center and innovative highland of regional development, and also the innovation source and power engine of regional development. In the past ten years, the Ministry of Education, 31 provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps have jointly laid out and built 229 collaborative innovation centers, strengthened in-depth cooperation with leading industrial enterprises and local governments, and provided strong support for industrial and regional development. The comprehensive service and deep integration of universities into the construction of international science and technology innovation centers in Beijing, Shanghai and Guangdong-Hong Kong-Macao Greater Bay Area have strongly supported Chengdu-Chongqing area and Wuhan to accelerate the construction of science and technology innovation centers with national influence. For example, Huazhong University of Science and Technology has been deeply involved in the photoelectric field for ten years, established 25 joint laboratories with related leading enterprises, and gradually established the advantages of national science and technology base cluster from basic research, key technological breakthroughs to achievements transformation and application. 130 high-tech enterprises have been transformed from school scientific and technological achievements, supporting China Optics Valley’s "optical core screen end network" industrial cluster to break through the 600 billion mark, and are striving to develop into a trillion-dollar industrial cluster. In the past ten years, colleges and universities have given full play to their regional advantages and disciplinary talents, strengthened the role of radiation through innovation, accelerated the gathering of scientific and technological resources, and helped to create regional innovation growth poles.

First, the position sensor is faulty.

Customer’s description: the vehicle fault light is on, and it takes a long time to take a taxi, so it is not easy to start. Read the fault code with a computer as follows

When I saw these fault codes, I already had a clue in my heart. Look at the fault code information, the core fault code, respectively.

Through this fault code, there were 34 times. When there is a problem with the position sensor, the computer can’t correctly identify the relative position, and then can’t determine the correct ignition time, which will lead to a failure that is not easy to start and takes a long time to start. It is consistent with the failure phenomenon described by the owner, and the position sensor is removed.

There are a lot of iron chips and oil stains on it. The sensor is a Hall sensor. The cause of the failure is the failure of the internal coil. After communicating with the customer, it was replaced.

Commissioning after installation, starting back to normal,

Troubleshooting.

Second, the mixture is too thin, and the oil-gas separator leaks.

Under the condition of idling hot car, check the opening by computer, read 3.3 groups of data streams, and the value is only 0.39%, but it runs normally, and the normal opening is greater than 1, even if it has just been cleaned, it is more than 1. Therefore, it can be judged that there is air leakage at the back end, and it is determined that the air leakage point is located in the oil-gas separator through further inspection.

Remove and replace.

Re-read 3.3 data streams after replacement, and the data returned to normal.

The value at idle speed is 1.18%.

Test run, troubleshooting.

Third, summary.

These two faults are all common problems of EA888, and they were solved easily without any special effort, mainly because there are more problems encountered at ordinary times, so there are fewer detours.

I hope it can help everyone.

　　On April 2nd, a news about bilibili UP owner’s initiative to stop the tide was released, which quickly triggered a hot discussion among netizens and boarded a hot search in Weibo.

　　Why do bilibili UP owners stop working one after another?

　　A number of UP owners announced that they would stop working.

　　On April 2nd, an up owner with nearly four million fans in bilibili said that his account was temporarily suspended and he was not sure when he would return. He said that at present, the whole team is in a state of loss and can’t support a team. On the other hand, at present, the creation has also encountered some development bottlenecks.

　　Bilibili up, which is still updating, said that the platform incentives are gradually decreasing, and the impact of short videos is also partly due to it. In addition, the number of original personal accounts in bilibili is gradually decreasing, while the number of accounts packaged by companies is gradually increasing, and the cost of video production is also lower.

　　According to incomplete statistics, those who announced the suspension this time include well-known suspense reasoning bloggers, top 100 UP owners in bilibili in 2019 @ Weird Jun (2.65 million fans), well-known game area blogger @ Xu Dawang (3.85 million fans), @-LKS-(3.11 million fans) who just won the top 100 UP owners in bilibili in 2022, and several middle-waist UP owners with hundreds of thousands to tens of thousands of fans.

　　"The reward mechanism in bilibili has been greatly adjusted this year." An UP owner with tens of thousands of fans in bilibili said that for a video content with little difference in data from last year, bilibili may only give the creator 1/3~1/2 of last year’s income.

　　The revenue here mainly refers to the "bilibili Creative Incentive Plan" launched by bilibili in January, 2018, which will evaluate the value of video traffic according to the data such as video playback volume, likes, coins and collections, and give cash rewards to UP owners according to the rules. However, in recent years, with bilibili’s sustained losses, the amount of incentives in bilibili has also continued to decline.

　　Last year, UP’s revenue was divided into 9.1 billion.

　　For bilibili UP owners, the realization of bilibili’s content mainly goes through two channels: platform incentive and business cooperation.

　　Platform incentive mainly refers to the incentive for the content creation of UP owners, that is, bilibili comprehensively evaluates the self-made content created by UP owners and provides corresponding rewards. The evaluation criteria include the amount of play, the amount of fans, and the amount of fans’ coin collection.

　　For commercial cooperation, the evaluation standard is much simpler, that is, to see how many commercial brands the UP owner can pull for the platform, and the more they pull, the greater the incentive.

　　In May, 2021, bilibili made adjustments to the creative incentive plan, and introduced a variety of assessment indicators, including broadcast channels, verification after user conversion, and adjusted the weights of different indicators. In fact, it is to increase the weight of business cooperation and reduce the weight of platform incentives. The standard that determines the income of UP owners is no longer the video quality, but who can receive advertisements better than who. As a result, the phenomenon of "traffic merger" has been caused. The income of the head UP owners who are suitable for receiving advertisements and have a large number of fans has been rising with the investment of the platform, while more waist and tail UP owners are simply unable to make a living on the platform.

　　For a long time, bilibili UP owners spontaneously produce and upload video content for their own interests and love, and the behavior of not pursuing economic benefits first is described as "generating electricity with love", which is also an important reason why bilibili can maintain the content and community activity. However, for most individual UP owners, the long-term "generating electricity for love" will eventually run out of electricity.

　　"Power generation with love" has never been able to support the "long-term stability" of a pan-community platform, and only by encouraging UP owners to expand their income through commercial cooperation can they really retain creators.

　　It is worth mentioning that bilibili’s share of the anchor has been relatively high in the industry.The 2022 financial report released by bilibili shows that about 9.1 billion revenues are distributed to UP owners.. In 2022, the operating cost of bilibili reached 18 billion yuan, of which the revenue share reached 9.1 billion yuan, including the incentive/share given to UP owners in the live broadcast and advertising business, which increased by 18% year-on-year.

　　The loss in 2022 was 7.5 billion.

　　The share price has fallen by more than 13% in the past year.

　　On March 30th, 2022 annual results were announced. The financial report shows that in 2022, the company achieved a total net turnover of 21.899 billion yuan, a year-on-year increase of 13%; The net loss was 7.5 billion yuan, a year-on-year increase of 10%.

　　From the perspective of revenue composition, at present, the main revenue comes from mobile games, value-added services, advertising, e-commerce and others. In 2022, the company’s game business achieved revenue of 5 billion yuan, a year-on-year decrease of 1%; Value-added services achieved a revenue of 8.7 billion yuan, a year-on-year increase of 26%; The advertising business revenue was 5.1 billion yuan, a year-on-year increase of 12%; E-commerce and others achieved a total revenue of 3.1 billion yuan, a year-on-year increase of 9%.

　　It is worth noting that in recent years, although the company’s revenue has been growing, the losses are also gradually expanding. From 2019 to 2021, the company achieved revenue of 6.778 billion yuan, 11.999 billion yuan and 19.384 billion yuan respectively, with year-on-year growth rates of 64.16%, 77.03% and 61.54% respectively; The net losses were 1.289 billion yuan, 3.012 billion yuan and 6.789 billion yuan respectively, and the accumulated losses in three years exceeded 11 billion yuan. In addition, from the perspective of changes in revenue growth rate, there has also been a slowdown since 2020.

　　However, in the 2022 financial report, in order to achieve profitability, the company launched a number of measures in 2022 to improve the efficiency of commercialization. And pointed out that the company’s gross profit margin increased from 19.0% in the fourth quarter of 2021 to 20.3% in the same period of 2022.

　　Meanwhile, according to the financial report data, the number of users in bilibili achieved steady growth in 2022. In 2022, the average daily active users of the platform reached 86.5 million, an increase of 29% compared with 66.8 million in the previous year; The average monthly active users reached 314.5 million, an increase of nearly 26% compared with 249.8 million in the previous year; The average monthly paying users reached 27.8 million, an increase of 24% compared with 22.4 million in the previous year.

　　In terms of business outlook, he said that new industry changes in 2023 require more efficient operation, and the company will continue to follow this path, putting profit first, accelerating the commercialization process and tightening expenditures. The company will continue to pay attention to the quality of users to achieve the growth of daily users and increase the ratio of daily users to monthly users. It is expected that the gross profit margin will increase and the loss will narrow in 2023.

　　In terms of share price, as of March 31, it was reported at HK$ 189.6 per share, and its share price fell by over 13% in the past year. The latest market value of the company is HK$ 78.7 billion, which is 80% lower than the high market value of over HK$ 400 billion when it went public in Hong Kong in March 2021.

"I am nearly 50 years old, and I have spent half my life in Shanghai. This is my hometown for me." This is Shanghai in the eyes of online writer Xiang Juan. "This is a very lively city, which can be described as’ moving around for a change’. With the change of my age, work and place of residence, every step I take, the scenery I see is completely different, but every step is a scenery, which is the reason why I like Shanghai. "

Just after the Millennium, Xiang Juan and her husband gave up their jobs in Xuzhou state-owned enterprises for the sake of their children’s education, and came to Shanghai with their children over one year old in their arms. At that time, she never thought that she would embark on the road of online literature creation in Shanghai. "I am not young, but I entered the business late. When I started writing online articles in 2011, I have been working for more than ten years and have been in charge of the human resources department." On April 26th, when she was interviewed by a journalist from Jiefang Daily Shangguan, she couldn’t help feeling the contingency of writing this experience.

Idle listening to falling flowers

"I am the first batch of chicken blood mothers." Xiang Juan said that letting children receive a better education in Shanghai was the only reason for their family to move. At that time, people around them invested heavily in their children’s education. And she started writing on the Internet, which was also accidentally related to the "Chicken Baby" incident. "Children’s junior high school is the most important test to teach their parents. I look for training or all kinds of information from major forums, and I have posted a few posts in order to mix my face, all of which are hot posts. Many people say that I write well, so why not try to write a novel? " On impulse, she wrote more than 3,000 words in qidian, but she didn’t expect to sign the contract the next day and officially entered the business.

On the website, Xiang Juan writes under the pseudonym "Idle Listening to Flowers". Compared with many authors, she was lucky. She became an instant hit when she wrote her debut novel "Nine Holies and Ten Beauties". Since then, she has successively created more than ten works, such as Jin Tong, Sheng Hua, Mo Sang, Hello, New Time, My Home Auntie and so on. "Writing is actually a process of reverse thinking and self-analysis. From the first novel" Nine Holies and Ten Beauties "to later works, the style and core have changed a lot. I think it is a step-by-step growth."

Idle listening to falling flowers

Among them, "My Home Auntie" was selected as the key works of online literature supported by the Chinese Writers Association in 2022 (excellent historical and traditional theme). This work focuses on traditional weaving, dyeing and embroidery techniques, and takes the outstanding women in the history of cotton textile in old Suzhou and Shanghai as the prototype, and tells the story that the heroine Li Xiaodong bravely grew up and changed the family status quo through her intelligence and perseverance. The creative process and inspiration of this novel have something to do with Songjiang, Shanghai, where Xiang Juan lives.

"The development of the whole Songjiang cotton textile industry is driven by women. When I read local chronicles or literati notes, I will see many great women. In addition, I especially like embroidery, weaving and dyeing, which is particularly easy to see in ancient towns and museums in the south of the Yangtze River, and even has a display of the production process. " Every time she sees these wonderful embroideries in the museum, she has the urge to write. "Chinese culture has a long history. It is very natural to write about our culture in such a splendid treasure house of history and culture."

Two years before she officially started writing My Home Auntie, she had begun to collect information consciously, such as the principle and atlas of traditional textile machinery, the differences between traditional machinery in different places, the development history of textile industry, and the collection of essays and pictures of China’s embroidered clothing. In terms of specific character conception, Xiang Juan remembers that she once saw the confession of a Shanghai weaver, telling her pride and self-esteem as a professional woman, and the three-dimensional vivid image of embroidered mother gradually took shape. "These odds and ends add up, and I want to write about this group of people who are engaged in the textile industry in Songjiang."

Idle listening to falling flowers

For Xiang Juan, Li Xiaodong is certainly the heroine in an ancient romance novel, and she undertakes the task of "dreaming" for readers; But the supporting roles around her are the group images that the author has spent a lot of effort to portray. "For me, the hostess is a clue. Following this clue, one potato will be pulled down. These are the so-called supporting roles. What I want to show readers is how good the potatoes I grow are. But we must have a rope. Without it, these potatoes can’t be pulled down. " Xiang Juan said that the real protagonists in the book are all kinds of women, and the characters she really wants to express are all in supporting roles. "There are many female characters in My Home, such as Li Xiaodong’s eldest sister, who is a very independent woman, and women who dress up as men as escorts. They are the people who really bring about changes in the society or industry in the book. Through the social beings they outline, people will see real life. "

Xiang Juan has the characteristics of the post-70 s generation. She loves her work, especially reading and writing. When she is not updating, she will read a lot, and the books in the study are piled everywhere. The content field of reading spans a lot and the subject matter is diversified. Recently, she has read many books about vagrant culture and is reading Wang Xuetai’s "Vagrant Culture and China Society". She also read Shimizu Reiko’s comic books, science fiction Dune, fantasy novel fire and ice, or Du Fengzhi’s Diary written by officials in the late Qing Dynasty. "The post-70 s generation is a very hard-working generation. For me, leisure after work is the most enjoyable. Just like on weekends, I get up in the morning to wash clothes and clean up. After all the housework is done, I still have half an hour of free time. At this time, my home was in good order and my clothes were hanging out. I made a cup of tea and sat on the balcony to blow. At this moment, I was in a very good mood. "

Idle listening to falling flowers

For the characters in her works, Xiang Juan expects to be "independent and able to make her own decisions", and she also expects to convey the theme of "women’s strength has never been absent in the process of history" to readers through various works. "In the future, I want to write a love story. It is not classified by male frequency or female frequency, nor is it limited to Zhai Men and Gong Dou. It is the life in a certain era. But no matter what the background is, I write stories around me. "

Laihua, whose real name is Xiang Juan, is a writer of Reading Group and a director of Shanghai Network Writers Association. Since I started writing in 2010, I have created more than ten works, such as Nine Holies and Ten Beauties, Flowers Bloom in Spring, Brocade, Shenghua, Nuan Jun, Mosang, Hello, New Time, My Home Auntie, etc. Their words are beautiful and exquisite, and their contents are fresh, interesting and unconventional, which are deeply loved by many readers.

CCTV News:The Yangtze finless porpoise is a national first-class protected wild animal in China and is known as the "giant panda in the water". Recently, in Yichang, Hubei Province, dozens of finless porpoises chased the waves along the Yangtze River and played with their heads, attracting many citizens.

At present, this Yangtze finless porpoise slowly pokes its head out of the river and playfully swims in the river; And this one kept changing its posture on the river, or swinging from side to side, or rolling its belly, as if showing off its swimming skills, and soon it attracted good friends to play together. This Yangtze finless porpoise took the baby’s learning skills, raised his head and chest, breathed and sank, and the little Yangtze finless porpoise baby learned exactly the same.

It is understood that the Yangtze finless porpoise is mainly distributed in the mainstream of the middle and lower reaches of the Yangtze River and in Dongting Lake and Poyang Lake. In recent years, with the continuous improvement of the Yangtze River ecology, the number of Yangtze finless porpoises observed in Yichang section of the Yangtze River has increased year by year.

　　On March 22nd, the National Health and Wellness Commission published the Implementation Guide for Regional novel coronavirus Nucleic Acid Detection Organization (Third Edition), which revised the "all staff" in the second edition of the guide to "regions", and the size of the regions was determined by the needs of epidemic prevention and control. It is emphasized that nucleic acid detection should have a clear goal and be targeted, and it cannot be "one size fits all"; Clearly promote the monitoring mode of "antigen screening and nucleic acid diagnosis" … What should the new edition guide look at?

　　　Why should we revise and issue the third edition of the guide?

　　Recently, the situation of epidemic prevention and control in China is severe and complicated, and the characteristics of Omicron mutant, such as fast spread, strong infectivity and hidden spread, put forward new and higher requirements for the organization to carry out nucleic acid screening. At the same time, in order to summarize and popularize the beneficial experience of nucleic acid screening in the early stage and guide local governments to solve the problems encountered in practice, the third edition of the guide was revised and formed.

　　　What are the main revisions?

　　It mainly revised the following aspects: First, it emphasized scientific accuracy and carried out nucleic acid detection in designated areas. The "all staff" in the second edition of the guide is changed to "area", and the size of the area is determined by the needs of epidemic prevention and control. The second is to further clarify the time limit for completion. The nucleic acid detection with defined scope shall be completed within 24 hours. The third is to add a number of special work classes. According to all the links and departments involved in regional nucleic acid detection, the local authorities were instructed to set up 9 work classes, including data statistics classes and sampling matching classes, and the responsibilities of the classes were specified. The fourth is to provide the basis for measuring the testing strength. The number of sampling personnel and nucleic acid detection ability required to complete nucleic acid detection within 24 hours in various places are given clear calculation guidance. The fifth is to streamline the technical requirements for testing. Combined with the application scope and actual operation requirements of the third edition of the guidelines, the existing requirements in the technical documents such as "novel coronavirus nucleic acid detection manual for medical institutions (Trial)" are not stated in this paper, but the management requirements such as sampling organization, transportation, detection and result disposal are further highlighted and clarified.

　　　What exactly does "area" mean?

　　"Area" includes sealed control area, control area and prevention area. The area may be as small as a building or as large as the whole city, which should be determined by the local epidemic prevention and control headquarters on the basis of scientific research and according to the actual needs of epidemic prevention and control, and adjusted dynamically.

　　　What are the considerations that emphasize the accurate delineation of the detection range? Will there be a large-scale full-scale inspection in the future?

　　It is very important for nucleic acid detection to improve the level of scientific and accurate prevention and control. Nucleic acid detection should be clear and targeted, not "one size fits all", and make effective use of valuable nucleic acid detection resources. Therefore, the third edition of the guide emphasizes the need for accurate and rapid flow investigation and strict community control. After scientific research, the scope that needs to be tested is delineated. The scope of nucleic acid detection is directly related to whether the risk source is clear or not, and also related to many factors such as whether the traceability of the epidemic is accurate, whether the infected people are widely distributed, and whether the isolation control measures are implemented. Whether it is necessary to carry out large-scale full-scale nucleic acid detection depends on scientific judgment and serves the needs of epidemic prevention and control.

　　　What are the key points to be paid attention to in developing regional nucleic acid detection?

　　To carry out regional nucleic acid detection, local party committees and governments must have strong organizational mobilization and deployment capabilities, and all departments should cooperate efficiently. Therefore, the "organization and management" part should be emphasized. In addition to organization and management, the local authorities should fully understand and prepare for the ability of nucleic acid detection in the region. Orderly organization of community sampling, information management of sampling detection, accuracy of sampling operation, avoidance of possible cross-infection during sampling, matching of sampling and inspection, accuracy of nucleic acid detection and scientific judgment after each round of detection are all key links that must be paid attention to.

　　　Will antigen testing be used in the process of tissue testing in various places?

　　In the third edition of the guide, antigen detection is mentioned about the detection strategy. All localities can promote the monitoring mode of "antigen screening and nucleic acid diagnosis" in combination with the relevant requirements of antigen detection in Covid-19, increase antigen detection as a supplementary means of regional nucleic acid detection, and organize the implementation after studying and refining the implementation plan.

Chen Qiufa, Secretary of CPC Liaoning Provincial Committee and Director of Liaoning Provincial People’s Congress Standing Committee (photo by Liu Liang)

　　CCTV News:On June 25th, the State Council held a press conference on "Liaoning Practice of Overall Revitalization and All-round Revitalization". In response to a reporter’s question, Chen Qiufa, secretary of the CPC Liaoning Provincial Committee and director of the Standing Committee of the Liaoning Provincial People’s Congress, said that in the past period, Liaoning’s political ecology was seriously damaged, and an important factor was the problem of selecting and employing people. Therefore, Liaoning regards selecting and employing people as a breakthrough to purify and repair the political ecology.

　　Chen Qiufa introduced that strictly administering the party in an all-round way is an important political guarantee for revitalization and development. In recent years, we have resolutely implemented the spirit of the important instructions of the Supreme Leader General Secretary and the major decision-making arrangements of the CPC Central Committee to manage the party and the party, taking party building as the greatest achievement, and putting the requirements of comprehensively and strictly administering the party throughout the whole process of all work, thus providing a strong political guarantee for revitalization and development. We have mainly focused on the following aspects:

　　First, insist on putting political construction first. We have conscientiously studied and implemented "Several Provisions of the Political Bureau of the Communist Party of China (CPC) Central Committee on Strengthening and Maintaining the Centralized and Unified Leadership of the CPC Central Committee" and "Opinions of the Central Committee of the Communist Party of China on Strengthening the Party’s Political Construction", and we have also formulated and issued measures for implementation in our province, educating and guiding cadres in party member province to firmly establish "four consciousnesses", strengthen "four self-confidences" and resolutely achieve "two safeguards". We will do a good job in the implementation of the spirit of the important instructions of the Supreme Leader General Secretary in Liaoning, and comprehensively implement the tasks of the central inspection, the central environmental protection inspector, the marine inspector, and the central special struggle against evil. We will carry out the Party’s mass line education and practice activities, the special education of "three strictness and three realities", the study and education of "two studies and one doing" and the theme education of "Do not forget your initiative mind, bearing in mind the mission", earnestly do a good job in activities such as "learning the important speeches of the Supreme Leader General Secretary, stressing honesty, understanding rules, observing discipline, boosting morale and promoting revitalization", and continue to "supplement calcium" and "cheer" for the majority of party member cadres. Carry out warning education in depth, and resolutely eliminate the bad influence of Bo Xilai and Wang Min’s pernicious influence and Liaoning’s systematic canvassing and bribery.

　　Second, establish a correct orientation for selecting and employing people. In the past period, Liaoning’s political ecology has been seriously damaged, and an important factor is the problem of selecting and employing people. We regard the selection and employment as a breakthrough to purify and repair the political ecology, thoroughly implement the party’s organizational line in the new era, conscientiously implement the standards for good cadres in the new era, and organize the formulation of various cadre management regulations. In recent years, we have formulated four management regulations for the promotion of party and government leading cadres, leaders of public institutions, leaders of provincial enterprises, and inspectors and deputy inspectors, and introduced 10 working methods such as daily understanding, analysis and judgment, motion brewing, communication and recommendation, actual assessment, annual assessment, appointment and dismissal talks, and cadre exchanges. In terms of cadre management, it has been institutionalized and standardized. Set up and light up the orientation of correctly selecting and employing people. Coordinate the resources of cadres in the province. Since October last year, 75 leading comrades of party and government in counties and districts have been newly appointed to promote cross-regional and cross-departmental exchanges of cadres. Practical exercise is the best training. In recent years, we have sent a large number of young cadres to take exercise, including more than 200 at the grass-roots level, more than 100 in Tibet and Xinjiang, and 12,000 in rural areas, so that they can experience the wind and rain, see the world, strengthen their bones and muscles and grow their talents in the front line of revitalization and development.
