　　March 25, 1995　　

On June 28th, CCTV reported that it was supposed to be the law enforcement department of traffic violators, but it acted as an "umbrella" for those who were rectified. Since June last year, Harbin has destroyed 251 "protective umbrellas" hidden in the traffic system in two batches. Hongsheng Wang, the former detachment leader of the municipal traffic administrative comprehensive law enforcement detachment, and Wang Wei, the former deputy detachment leader of the municipal traffic police detachment, have been "double-opened" and transferred to judicial organs for legal treatment.

129 law enforcers act as umbrellas for personal gain.

The phenomenon of "black car" in Harbin has a long history. As early as 2007, some people reported that some people bought scrapped vehicles as taxis and operated in different regions. By 2015 and 2016, the phenomenon of "black car" reached its peak, and even openly competed with regular taxis to grab passengers, asking for exorbitant prices, looting and extortion, and passengers suffered greatly.

Hongsheng Wang, the former detachment leader of Harbin Traffic Administrative Comprehensive Law Enforcement Detachment, accepted the trial site (data picture)

As soon as the "black car" is rectified, it will disappear, and if it is not rectified, it will be on the road again. For more than 10 years, the problem of "black cars" has been banned and repeated. The reason is that, in addition to the benefit drive, the "umbrella" within the management department is the direct cause of the proliferation of "black cars".

"We must resolutely guard against and correct what the people oppose and hate", and implement the requirements of the Supreme Leader General Secretary. The main leaders of Heilongjiang Province and Harbin clearly put forward that it is an important task to punish illegally operated vehicles and investigate and deal with "protective umbrellas" to safeguard the interests of the people. On June 26 last year, a task force was formally established in Harbin to crack down on illegal operation of vehicles and strictly investigate the "protective umbrella" behind them.

The Municipal Commission for Discipline Inspection dispatched more than 30 business backbones of discipline inspection and supervision offices to participate in special rectification actions throughout the process. In the early stage, in order to investigate the problem more thoroughly, the cadres of the Commission for Discipline Inspection disguised themselves as unannounced visits, ventured to take a "black car" many times to understand the situation and mastered a lot of valuable information. After a month’s careful arrangement, starting from the early morning of July 27th, the Municipal Commission for Discipline Inspection organized and coordinated the public security, transportation and other departments to launch the "closing the net" action.

After checking 16,800 related vehicles, seizing 214 illegally operated taxis, knocking out 7 "black car" gangs, and handing over the clues of 174 illegally operated taxis to the public security organs, the "protective umbrellas" hidden behind them were revealed one by one.

On November 13th of that year, the Supervision Bureau of Harbin Municipal Commission for Discipline Inspection publicly reported the investigation and punishment of party member cadres and staff acting as "protective umbrellas" for illegally operating taxis, and severely investigated and held 129 party member cadres and staff accountable.

Among the 129 public officials notified, some involved the supervision department’s ineffective performance of the main responsibility, dereliction of duty, some involved the inaction and disorderly actions of law enforcement departments, some party member cadres lost their principles, interceded for illegal operators to ask for cars and mitigated punishment, some party member cadres tipped off illegal operators or tried to cover up the people involved, and even worse, they abused their powers because of accepting benefits and acted as "protective umbrellas" for the illegal operation of "black car" gangs.

Seven cadres, including Hongsheng Wang, the detachment leader of the Municipal Traffic Administrative Comprehensive Law Enforcement Detachment, and Li Lun, the political commissar, were expelled from the Party and public office for allegedly abusing their powers to commit crimes, harboring crimes or accepting bribes, and were transferred to judicial organs for legal treatment. Other party member cadres were punished by probation, dismissal of their posts in the Party, and severe warnings within the Party, depending on the seriousness of the case, for accepting bribes, informing people, caring for intercession and other violations.

Eight party member cadres, including Tan Hongzhi, former party secretary and director of the Municipal Transportation Bureau, Qi Ming, deputy director, and Liu Wei, leader of the discipline inspection team, were dismissed from their posts in the Party and removed from their posts by the administration for failing to perform their main responsibilities and supervisory responsibilities.

Among the 122 "protective umbrellas", 108 people are involved in the public security system.

It’s only been more than half a year since the last briefing. On June 25th, the Supervision Committee of the Harbin Municipal Commission for Discipline Inspection informed 122 leading cadres and public officials about the issue of "protective umbrellas" for the "crazy trucks". Among them, Wang Wei, deputy detachment leader of the municipal traffic police detachment, Ming Changqing, team leader of the municipal traffic police Daoli, and Yu Guangjun, etc. 11 people were transferred to judicial organs for legal treatment.

Wang Daoan, the captain of the city traffic police, Li Renming, the captain of Taiping, Han Ming, the captain of Haxi, and Gao Wenfeng, the political commissar of Acheng Brigade, were dismissed. Zhang Jidong, the former captain of the patrol brigade of the municipal traffic police detachment, and Pan Guangping, the captain of the bungalow, were respectively punished by party discipline and government affairs.

Ma Tengxiang, former deputy director of Nangang Branch of the Municipal Public Security Bureau, intervened in law enforcement and provided protection for illegal acts of trucks. He was punished by staying in the party and determined his retirement benefits according to his non-leadership positions at the official level.

Fourteen public officials from Daoli District, Daowai District, nangang district, Xiangfang District, Songbei District Urban Management Law Enforcement Bureau and Transportation Management Office of the Municipal Transportation Bureau failed to perform their supervisory responsibilities, and were punished by party discipline and government affairs respectively.

These 122 leading cadres and public officials have various ways to violate the law and discipline, some abuse their powers to give the green light, some reveal secrets to sell people’s feelings, some organize groups to violate the rules, some interfere in law enforcement, some interfere in the project for personal gain, and some release water from the source to make changes, which seriously undermines the authority and credibility of law enforcement.

It is worth noting that among the 122 "protective umbrellas", 108 people are involved in the public security system, including 100 public security traffic police.

In order to make the cadres of public security organs deeply learn the painful lessons of this case, earnestly rectify the problems, thoroughly eliminate the negative effects, and reshape the new image of public security traffic police, on the 27th, Harbin public security organs held a warning education conference.

The Harbin Public Security Bureau has studied and promulgated the "six whatevers and six unifications" prohibition iron regulations, thoroughly investigated and sorted out hidden dangers in the overall scope, and comprehensively carried out special rectification in terms of team style, police handling, law enforcement quality, and collusion between traffic police and police stations and police officers.

At the same time, a key work inspector group was set up to station in the traffic police detachment to comprehensively supervise the work of building a clean and honest party style, rectifying work style, and providing four zero services. Solidly promote the strict management of the party and the police in an all-round way, and regard June 27 of each year as the overall "warning education day" to guide the education of the whole police not to forget the shame and alarm bells.

The Long March is a manifesto

The Long March is a propaganda team.

Long March is a seeder.

　　　　　　 In October, 1934, the Chinese Red Army of Workers and Peasants began a long March that was arduous and shocked the world. According to statistics, during the Long March, the Central Red Army passed through 11 provinces, crossed 18 mountains, crossed 24 rivers, crossed grasslands and climbed snow-capped mountains, with a journey of about 25,000 miles. Finally, in October 1936, the three main forces of the Red Army joined forces, marking the victory of the Long March and creating a great miracle in human history! Through the Long March, the Communist Party of China (CPC) publicized our Party’s anti-Japanese proposition of going northward, sowed revolutionary kindling in various places along the Long March, and also expanded the influence of the Communist Party of China (CPC) and the Red Army in the whole country.

　　　　　　 On August 1, 1965, in order to commemorate the 30th anniversary of the victory of the Red Army’s Long March, a large-scale vocal suite "Long March Suite — — The red army is not afraid of the expedition.

　　　　　　 On the stage of this issue of Le Ling Singing, we welcome an old comrade-in-arms chorus art troupe formed by retired actors of Long March Suite and some singers who love Long March Suite. They will tell us why Long March Suite has been sung for decades and how it has become a classic among classics.

　　　　　　 Let’s meet the actors who premiered 55 years ago. Time can only take away youth, but it can’t take away lofty ideals and firm beliefs!

Chorus of revolution

The revolution of chorus

　　　　　　 Referring to the response after the premiere of "Song of the Long March", as the original general director, Grandpa Han Rongshi, who is 88 years old this year, said: "The situation at that time is still vivid. After the performance, it was an instant hit and was warmly welcomed. Comrade Zhu Jianer, a musician, wrote an article saying that "Long March Songs" is a chorus of revolution and a revolution of chorus. The chorus of revolution refers to the content of "Long March Songs" and describes the whole process of the Long March. The revolution of chorus is about form. It breaks through the original form of chorus wearing a dress and standing on the stage like a wall, adding performances, actions and scenes, which is very visual and makes the audience enjoy and be satisfied. "

　　　　　　 Wang Shuli, a violinist who also premiered, is currently the head of the Chorus Art Troupe of the old comrades-in-arms. He said that the reason why the Long March Ensemble is praised as a classic work in chorus is that it has achieved "three unifications".

Walking through Qian Shan

Highlight the revolutionary responsibility

　　　　　　 A landmark classic works, the reason why it can be sung so far, the reason why it can move people’s hearts, this is inseparable from its artistic creation. Every time I recall this past, I have been performing for more than 50 years, and Ma Ziyue, the bass singer who has performed more than 1,000 Long March Songs, is still impassioned.

The image is full of glory

Classic eternal inheritance

　　　　　　 In the process of creation, rehearsal and performance, The Long March Songs received the cordial care and guidance from Premier Zhou Enlai. After the premiere on August 1, 1965, Premier Zhou watched the Long March Songs three times in a month on August 6, August 24, August 27, and learned every song. In the same year, 18 members of the choir also visited Albania with Premier Zhou, including Han Rongshi, Ma Ziyue and Yang Zhenhui.

　　　　　　 Premier Zhou, who loves "Song of the Long March" so much, only left a group photo with the members. Speaking of this past, the 87-year-old grandmother Xie Gongcan, the former conductor assistant of the Long March Songs, was still very excited.

　　　　　　 As an epic red classic, "Long March Songs" has been sung all over the country, infecting generations of Chinese people, and has been sung ever since. It has been 55 years since it premiered in 1965. Although they were full of youthful hair, they still used their songs to inherit the Long March Songs and carry forward the spirit of the Long March. Today, on the stage of "Singing in the Age of Music", they are once again dressed in battle, and continue to present us with the original classic chapter with the passion of that year.

　　62.4%　

　　Contribution rate of agricultural science and technology progress　

　　To build an agricultural power, the sharp weapon lies in science and technology. In recent years, China’s agricultural science and technology innovation ability has been steadily improved, and the contribution rate of agricultural science and technology progress has increased from 54.5% in 2012 to 62.4% in 2022, which has provided strong kinetic energy for the high-quality development of agriculture. Science and technology are the fundamental way to stabilize and increase grain production. All regions and departments are guided by tackling key agricultural core technologies and oriented by industrial demand, focusing on chassis technology, key agricultural machinery and equipment, and constantly strengthening agricultural science and technology support.

　　With the support of science and technology, farming will become a "smart farming". Modern information technologies such as the Internet of Things, big data and Beidou navigation have been accelerated in planting production, and technologies and equipment such as precision sowing, smart irrigation and plant protection drones have been widely promoted. Sending skills to the fields and serving the villages, nearly 500,000 agricultural extension workers in China play an irreplaceable role in stabilizing grain supply, increasing production and income. A new technology has landed, and the fields are full of scientific and technological kinetic energy, highlighting the hard support of the "golden pole" of agricultural modernization. With the help of science and technology, agricultural production is constantly improving quality and efficiency.

　　1 billion mu　

　　Built-up area of high standard farmland　

　　Cultivated land is the lifeblood of food production, and farmland construction is a key measure to consolidate the foundation of food security in all directions. In recent years, with the joint efforts of various regions and departments, the work of farmland water conservancy has been solidly promoted, and the construction of high-standard farmland has been steadily accelerated, which has played an important role in ensuring the stable and safe supply of grain and important agricultural products. By the end of 2022, a total of 1 billion mu of high-standard farmland had been built in China, thus ensuring a stable grain production capacity of more than 1 trillion Jin, providing a basic support for ensuring a stable and safe supply of grain and important agricultural products. In the first ten months of this year, about 60.5 million mu of high-standard farmland construction was completed nationwide.

　　High-standard farmland has strong ability to preserve soil, fertilizer and water, and the average grain yield per mu is generally increased by 10%-20%, with high and stable yield, drought and flood, and green planting … At present, the quality of cultivated land in China has entered a stage of continuous improvement and overall improvement.

　　Insist on storing grain on the ground and storing grain in technology, vigorously promote the construction of farmland water conservancy and high-standard farmland in all localities, and continuously improve the quality of cultivated land, laying a solid foundation for ensuring national food security and accelerating the construction of an agricultural power.

　　73%　

　　Comprehensive mechanization rate of farming and harvesting　

　　Advanced mechanical equipment is an important material basis for storing grain in technology. At present, the comprehensive mechanization rate of crop cultivation and harvest in China has exceeded 73%, with 1.8 million sets of agricultural machinery and equipment equipped with Beidou positioning operation terminal, and the foundation of granaries in big countries has been continuously consolidated.

　　Agricultural mechanization has brought about changes in production methods. Sprinkle the medicinal plant protection drone, and you can apply fertilizer accurately by clicking the screen of the mobile phone; The electric-driven high-performance seeder cooperates with Beidou navigation and driving, and the linear error is less than 2.5 cm … In the sky, in the ground and in the internet, all kinds of intelligent agricultural machinery and equipment "show their talents", and mobile phones have become "new farm tools".

　　Agricultural mechanization is an important guarantee for grain saving and loss reduction. In the past, harvesting wheat by hand was time-consuming and laborious, and the loss was 5%-8%. Nowadays, the average harvest loss under normal conditions is only about 1%, and the new intelligent Beidou navigation combine can further reduce the harvest loss.

　　At present, agricultural mechanization is accelerating from the cultivation and harvesting of main crops to the whole process of grain production such as straw treatment and drying. Vigorously promote agricultural mechanization and intelligence, and insert the wings of science and technology into agricultural modernization.

　　23 million people　

　　Number of rural practical talents　

　　The key to rural revitalization lies in people. At present, there are more than 23 million rural practical talents in China, of which 8 million have cultivated high-quality farmers. In recent years, the demonstration and driving ability of rural practical talents has been continuously enhanced, and more and more high-quality farmers have joined the vast countryside. In 2022, the proportion of high-quality farmers who obtained the titles of peasant technicians and national vocational qualification certificates increased by 6.64 percentage points and 3.46 percentage points respectively compared with that in 2021. The participation of a large number of new forces such as college graduates and migrant workers has promoted the continuous improvement of the rural talent team structure.

　　At present, all localities and departments actively build nests to attract phoenix, strengthen the combination of local training of rural talents and external introduction, implement talent engineering projects, increase policy support, optimize the entrepreneurial environment and corresponding services, and guide more talents who love agriculture, understand technology and are good at management to join modern agriculture and rural construction. We will implement the project of cultivating "Head Goose" for rural industry revitalization leaders, carry out training for rural practical talents, further give full play to the leading role of high-quality farmers in the fields of agriculture, rural areas and farmers, and inject new kinetic energy into rural comprehensive revitalization.

　　96%　

　　Coverage rate of improved varieties of crops　

　　Seed is the "chip" of agriculture, and improved varieties play a key role in promoting grain production. In recent years, the revitalization of seed industry has been solidly promoted and a number of breakthrough results have been achieved. At present, the coverage rate of improved varieties of crops in China is over 96%, the contribution rate of improved varieties in agricultural production is over 45%, and the area of self-selected varieties accounts for over 95%.

　　This year is the third year of seed industry revitalization in China. As of October, more than 530,000 germplasm resources of crops, livestock and poultry and aquatic products have been newly collected in China, and the "national team" of improved seed breeding consisting of 216 crop seed production bases and 300 livestock and poultry breeding stations has improved its seed supply support capacity from 70% to 75%. Generally speaking, China’s seed science and technology has been at the advanced level in the world. This year, all localities focused on promoting high-oil and high-yield soybean varieties, the quality of soybeans was significantly improved, and the variety structure was further optimized.

　　Promoting the revitalization of seed industry for a long time. It is necessary to give further play to the institutional advantages, accelerate the self-reliance and self-reliance of high-level seed industry science and technology, guide resource elements to gather in seed industry enterprises, and realize the modernization of the whole industry chain of seed industry.

　　6.2 million　

　　Number of new agricultural management entities　

　　Strong management system is one of the important characteristics of a strong agricultural country. By the end of September this year, there were more than 2.21 million farmers’ cooperatives and nearly 4 million family farms, and the number of new agricultural business entities reached 6.2 million. More than 1.07 million organizations have provided socialized services and become farmers’ intimate "field nannies", serving more than 91 million small farmers, covering over 1.97 billion mu.

　　Organize the advantages of farmers to appear. Farmers’ cooperative members take farmers as the main body, organize small farmers to carry out specialized production and large-scale operation on the basis of stabilizing the contracted management of farmers’ families, and cooperate to break into the market, thus effectively improving the efficiency of agricultural operation. As an effective organizational form to develop moderate scale management and modern agriculture under the market economy, cooperatives and family farms give new connotations to the two-tier management system and inject vigorous vitality into the rural basic management system.

　　Service-driven ability is enhanced. The business scope of cooperatives and family farms covers the production of major agricultural products such as grain, cotton, oil, meat, eggs, milk, fruits and vegetables, tea, etc., and has carried out contiguous planting and large-scale feeding, making a number of advantageous industries with "township name" and "local name" bigger and stronger, and promoting the integrated development of rural primary, secondary and tertiary industries.

　　Supreme Leader: Biodiversity is not only the foundation of sustainable development, but also the goal and means. We must use the way of nature to nourish all things, seek development opportunities from the protection of nature, and achieve a win-win situation for ecological and environmental protection and high-quality economic development.

　　This sentence is from the important speech delivered by the Supreme Leader President at the United Nations Biodiversity Summit on September 30, 2020.

　　Biodiversity is the result of billions of years of development and evolution of life on earth, and has important ecological, economic and cultural values for human survival and development. Protecting and restoring biodiversity and improving the diversity, stability and sustainability of ecosystems are conducive to improving our living environment, increasing food and resource supply, and promoting sustainable economic and social development. Conversely, if biodiversity is lost, ecosystems will be out of balance and human survival and development will lose an important foundation.

　　China has a vast territory, land and sea, and has given birth to rich and unique ecosystems, species and genetic diversity. As one of the countries with the richest biodiversity in the world, China has always attached great importance to biodiversity conservation. Especially since the 18th National Congress of the Communist Party of China, under the guidance of the Supreme Leader’s ecological civilization thought, all localities have adhered to ecological priority and green development, and continuously strengthened and innovated biodiversity protection measures.

　　为了保护重要自然生态系统和生物资源，目前，我国把超过30%的陆域国土面积划为生态保护红线，可有效保护90%的陆地生态系统类型和74%的国家重点保护野生动植物种群。经过多年移民搬迁和生态修复，我国设立的第一批5个国家公园有效保护了东北虎、大熊猫等珍稀野生动物及其栖息地，成为万物和谐共生的美好家园。同时，为保护一些濒危物种，我国相继设立国家植物园、野生动物救护繁育基地、种质资源库、基因库等，加大对濒危野生动植物的迁地保护，加强对生物遗传资源的收集保存。为保护候鸟迁徙通道，许多地方加强当地湿地保护，让水草丰茂的栖息地成为候鸟迁徙途中的重要“驿站”。随着生物多样性保护宣传教育和科普活动持续开展，公众参与生物多样性保护的方式更加多元化，参与度全面提高……经过不断探索，我们走出了一条中国特色生物多样性保护之路，各地也在保护自然中逐渐找到适合自身的发展机遇。比如，一些地方在国家公园以外的周边地区发展生态旅游业、林下经济等，让从保护区搬迁出来的当地百姓端上“绿饭碗”，吃上“生态饭”。

　　The drug problem is related to national security, the rise and fall of the nation and the well-being of the people. It is the consistent position and firm proposition of the China government to strictly control drugs. In the past 20 years, faced with the severe challenge of the rapid development and spread of the drug problem, the China government has always attached importance to drug control, insisted on incorporating drug control into the economic and social development plan as an important part of national security and social stability, mobilized all social forces, took all necessary measures, and tried its best to ban drugs and benefit the people.

　　In recent years, especially since the 18th National Congress of the Communist Party of China, under the strong leadership of the CPC Central Committee, the State Council and local party committees and governments at all levels, all relevant departments in various regions have adhered to source management, systematic management, comprehensive management, and legal management, and insisted on taking multiple measures to prohibit planting, trafficking, and smoking. Through unremitting efforts, China’s drug control struggle has achieved remarkable results.

　　Mobilize all forces to form a new pattern of comprehensive drug control

　　Since the late 1990s, the drug situation has become increasingly severe and complicated. Faced with this situation, the CPC Central Committee and the State Council have made a series of strategic decisions to strengthen drug control work, and the responsibility system, leadership system, working mechanism and guarantee mechanism for drug control work have been gradually established and improved, forming a new pattern of comprehensive drug control with unified leadership of governments at all levels, organization and coordination of drug control committees, respective responsibilities of relevant departments and extensive participation of social forces.

　　In 1990, the Government of China established the National Narcotics Control Committee composed of 25 departments, including the Ministry of Public Security, the Ministry of Health and the General Administration of Customs, to study and formulate important policies and measures in drug control, coordinate relevant major issues, and lead the national drug control work in a unified way. In 1998, the State Council approved the Ministry of Public Security to set up an anti-drug bureau. Since the national people’s war against drugs was launched in 2005, according to the development and changes of the drug problem in China, the State Council has repeatedly adjusted and enriched the member units of the National Narcotics Control Committee to meet the needs of the anti-drug struggle. At present, the number of member units of the National Narcotics Control Committee has reached 38, and working groups on anti-drug publicity and education, anti-drug investigation information, and drug prohibition and detoxification have been established.

　　Adhere to drug control according to law and gradually improve the legal system of drug control.

　　The government of China attaches great importance to the construction of the legal system of drug control, constantly speeds up the pace of drug control legislation, and has formulated and promulgated a series of laws and regulations. The legal system of drug control has been gradually improved, and drug control according to law has become the guiding principle of drug control work.

　　From the 1970s to the 1990s, the China Municipal Government successively promulgated the Criminal Law, the Customs Law, the Regulations on Administrative Penalties for Public Security and other laws and regulations. On June 1st, 2008, China’s first law comprehensively regulated drug control — — People’s Republic of China (PRC) Anti-drug Law was formally implemented. As a book summarizing China’s experience in drug control for many years and absorbing the essence of international drug control legislation, it provides legal guarantee for comprehensively strengthening drug control work under the new situation, and China’s drug control work has thus entered a new historical stage of comprehensive promotion according to law.

　　At present, a system of anti-drug laws and regulations has been formed at the national level in China, with the Criminal Law, the Anti-drug Law, the Regulations on Drug Rehabilitation, the Regulations on the Management of Precursor Chemicals and the Regulations on the Management of Narcotic Drugs and Psychotropic Substances as the main body, and local governments have successively formulated a series of supporting laws and regulations, providing a powerful legal weapon for the anti-drug struggle.

　　Contain drug sources and crack down on drug crimes.

　　China’s anti-drug department has always maintained the trend of cracking down on drug crimes, improved the three-dimensional prevention and control system of land, sea and air mail, and innovated the methods and means of drug enforcement, which severely cracked down on and effectively deterred drug crimes.

　　First, vigorously strengthen source blocking and interception to effectively curb the source of drugs. The anti-drug department of China has continuously improved the "three lines of defense" of blocking the first line of the border, checking the second line of the mainland and cutting the main roads, airports, stations and docks, forming a three-dimensional prevention and control system covering the main land, sea, air and postal routes.

　　Second, we will continue to carry out special anti-drug campaigns and effectively strengthen investigation and solving cases. Since the people’s war against drugs was launched, a series of special actions such as "pulling out nails" have been organized against foreign drug lords, and a large number of serious cases have been successfully cracked, and more than 80 domestic and foreign drug lords and important drug dealers, including Liu Zhaohua, Han Yongwan, Cai Aishan and Zhong Wanyuan, have been arrested.

　　The third is to comprehensively deepen the key rectification of drug control and effectively solve the prominent drug problem. By stepping up efforts to rectify drug trafficking and drug-related problems of special groups, 38,900 drug traffickers were arrested nationwide in 2015 alone. By using satellite remote sensing technology, the "Tianmu" series of drug shoveling operations were continuously carried out, and it was found that the illegally planted opium poppy was completely eradicated. Since the people’s war against drugs was launched in 2005, more than 1 million drug-related crimes have been cracked, 1.15 million drug suspects have been arrested and 751 tons of various drugs have been seized.

　　Prevention education is given priority to, and people’s awareness of drug control is generally improved.

　　The Anti-drug Law of People’s Republic of China (PRC) defines the policy of "prevention first" in anti-drug work, and stipulates the anti-drug publicity and education in a special chapter.

　　Public security, education, civil affairs, judicial administration, culture, trade unions, the Communist Youth League, women’s federations and other departments insist on taking teenagers, unemployed people and migrant workers as the focus of anti-drug publicity and education, create rich carriers of brand education activities, organize anti-drug publicity activities covering the whole year with the national anti-drug publicity month in June as the focus, and promote anti-drug publicity and education into communities, schools, units, families, places and rural areas.

　　At present, China has established 9 national demonstration bases for drug prevention education, more than 20 provincial anti-drug education bases, more than 700 anti-drug social organizations and more than 1 million anti-drug volunteers. The annual growth rate of newly discovered heroin users has dropped from 13.7% in 2008 to 6.6% in 2013.

　　Advocating people-oriented, actively educating and saving drug addicts

　　In view of the serious harm caused by drug abuse to drug addicts, their families and society, we have comprehensively used legal, administrative, economic, educational and medical means to control the drug problem, and education has saved a large number of drug addicts.

　　At present, 57 drug rehabilitation places have been built in China, and 95,000 drug rehabilitation personnel have been resettled, which has played a positive role in ensuring people’s livelihood and maintaining social harmony and stability.

　　In recent years, China has made great efforts to promote community detoxification and community rehabilitation, with towns and streets as the main body, relying on the masses and communities, mobilizing social forces, developing anti-drug social workers, and vigorously implementing the "August 31" community detoxification and community rehabilitation project. In the past five years, 27,000 community drug rehabilitation and community rehabilitation offices have been established nationwide, with 27,000 full-time drug control social workers and 68,000 part-time social workers. A total of 950,000 person-times of community-based drug rehabilitation have been carried out nationwide, and more than 1.2 million people have given up drug addiction for more than three years.

　　Strictly prevent illegal loss and strengthen the control of precursor chemicals

　　Proceeding from the fact that China is a big producer and exporter of chemicals, the national drug control department has earnestly implemented the 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.

　　Over the years, China has always attached importance to the "two-way investigation" in border areas and entry and exit ports, which not only prevents drugs from entering the country, but also prevents precursor chemicals from being smuggled out of the country. At the same time, an international verification system for the import and export of precursor chemicals has been established jointly with the United Nations anti-drug agencies and relevant national authorities, and a management information system for precursor chemicals has been established, which has implemented information management for the production, operation and circulation of precursor chemicals. Over the years, China has actively participated in Operation Purple, Operation Topaz and Operation Prism carried out by the United Nations anti-drug system, and cooperated closely with the Shanghai Cooperation Organization to further strengthen the international verification of precursor chemicals exported by key varieties and countries.

　　Since the People’s War against Drugs, more than 23,000 tons of precursor chemicals and non-regulated chemicals have been seized through strict investigation, and 20,500 tons of precursor chemicals have been prevented from being exported through international verification.

　　Actively fulfill international conventions and make contributions to the world drug control cause.

　　The Government of China has always attached importance to international cooperation in drug control, and, as a responsible big country, has always followed the principle of "extensive participation, shared responsibility, comprehensive and balanced drug control strategy, and emphasis on alternative development" put forward at the twentieth special session of the General Assembly on drug control, and earnestly implemented international drug control conventions.

　　Actively promote regional bilateral and multilateral drug control cooperation. The Government of China has hosted many important multilateral international conferences, continuously deepened the mechanism of Memorandum of Understanding (MOU) on drug control cooperation in Greater Mekong Subregion, the mechanism of "ASEAN+China" on drug control, the mechanism of Shanghai Cooperation Organization on drug control, and the mechanism of BRICS countries on drug control, and actively demonstrated China’s influence in the international drug control field.

　　Actively promote law enforcement and security cooperation in Mekong River Basin. In close cooperation with relevant countries, the case of "October 5" Mekong River was successfully solved in 2011, and naw kham, the first offender of the "Golden Triangle" mega-armed drug trafficking group, and key members were arrested. Leading the establishment of a law enforcement and security cooperation mechanism in the Mekong River Basin of China, Laos, Myanmar and Thailand, and continuing to carry out joint anti-drug operations to jointly crack down on transnational drug crimes and completely destroy criminal groups that have long endangered the security of this basin.

　　Actively carry out foreign law enforcement training, equipment and material assistance exchange and alternative development. China has gradually developed from a recipient country to an annual donation of US$ 1 million to the United Nations Office on Drugs and Crime (UNODC), and has trained nearly 2,000 drug enforcement officials for Myanmar, Laos, Cambodia and other countries within its capacity.

This article comes from WeChat WeChat official account:Interface news (id: wowjiemian), Author: Zeng Yanglin, You Miao, Editor: Peng Jieyun, original title: "Is the end of the Internet lending? Revealing the Financial Traffic Business of Video Head Players, the head picture comes from: vision china.

"Get a free video VIP member for one month", "Get a monthly card for xx video members within a limited time" and "Get a free VIP for 18 months" … Nowadays, you can see the gimmick of "get a free VIP" on many video platforms, only to find that they are all diverting the loan service.

"The end of the Internet is lending." In this regard, some netizens joked.

Customer diversion for P2P online lending business was once a steady business for major video platforms. At present, although P2P has withdrawn from the historical stage, it has not stopped the ambition of realizing the traffic of these companies. It is understandable to do financial business based on traffic, but there are many hidden risks such as infringement and disclosure of personal privacy, false information propaganda, low-interest induced lending, and loan bundling insurance, which deserves the vigilance of head video platforms.

As the head platform for short video and long video, Tik Tok, Aauto Quicker and "Ai Youteng"(Iqiyi, Youku, Tencent Video)What is the layout of financial services? The interface journalist test found that the financial depth of the above five video head platforms App layout has its own speed. Some are deeply rooted in the layout, while others always exercise restraint.

First, iQiyi is the most radical.

In the long video head platform "Ai Youteng", iQiyi’s financial layout is the largest, followed by Tencent Video, while Youku is relatively restrained and conservative.

Interface journalists combed and found that,Iqiyi cooperates with a number of institutions to guide the flow of a number of financial lending products, and it also has a credit service platform "Xiaoye Loan".

When the interface journalist clicks "My Wallet" on the iQiyi App, an advertisement pop-up window of "Free VIP membership for one month within a limited time" appears. After clicking "Free Collection", he immediately jumps to the page of "Wing Pay Sweet Orange Borrowing Money", which shows that "the first loan will give a one-month iQiyi VIP, and the new user will receive a 30-day first interest-free coupon, which will reach 750 yuan at the highest".

According to the page, "Wing Pay Sweet Orange Borrowing" is a borrowing platform for Wing Pay under China Telecom. Users can borrow up to 200,000 yuan, with an annualized interest rate of 7.2%.(subject to approval)The loan will arrive in 3 minutes at the earliest, and the source of funds is immediately consumer finance co., ltd.

In addition to guiding the lending products of "wing payment and borrowing money from sweet orange", a number of lending products are also recommended in "My Wallet" of iQiyi App Android client, including "Xiaoye Loan" under iQiyi, "Borrowing Flowers" under Ctrip Finance, "Withdrawing Money" under Zhongyuan Consumer Finance, saving money, 360 IOUs under 360 subjects and 360 small change flowers, Gome Easy Card and so on.(orange staging)Credit products such as small win and easy loan, "rich flowers" under Du Xiaoman Finance, "Zhongan loan" under Zhongan Insurance, Minsheng grain loan under Minsheng E-commerce, Suning Financial willful loan, and Lehua card under installment music.

Photo: Zeng Yanglin, a lending product diverted by iQiyi App, arranged it.

However, the interface journalist also noticed that compared with the Android mobile phone client, there are very few lending products recommended in the Apple iOS client of iQiyi App, and only iQiyi’s "Little Bud Loan" and Zhongyuan Consumer Finance "Raise Money" and Wing Pay three products.

Figure: Iqiyi App shows comparison on the lending platform of Android client and Apple client.

After testing, the interface journalists found that except for its platform "Xiaoya Loan", the rest of the credit products could not be directly borrowed on the iQiyi App, only to let users register as users of the loan platform, and then remind them that they need to download the corresponding App or pay attention to WeChat official account before borrowing.

The customer service of Xiaoya Loan told the interface journalist that Xiaoya Loan was developed, operated and managed by iQiyi, and all loan products and/or services were provided by regular licensed financial institutions with loan issuance qualifications.

Previously, when the product was launched at the end of 2019, the official said that Xiaoya Loan was independently responsible by licensed financial institutions and managed the whole process services such as risk control review, fund supply, post-loan handling and risk taking. iQiyi provided users with internet financial information and provided technical support for financial institutions and user credit services.

From the product description, iQiyi provides loan assistance services for Xiaoya Loan. According to public information, iQiyi has not yet obtained any financial-related licenses.

Second, Tencent video is the diversion of its own products, and Youku only cooperates with banks to open cards.

Comparatively speaking, Tencent video is not so radical, it only provides pure diversion service, and more serves Tencent’s own system.

Tencent Video App’s credit product "Goose Spend Money" in the financial sector is provided by Tencent’s Weizhong Bank, with a maximum loan amount of 50,000 yuan and an annualized interest rate.(simple interest)Minimum 7.2%. In addition, Tencent Video App also showed the insurance products of Weibo, an insurance brokerage platform of Tencent, including millions of medical insurance, accident insurance and aviation delay insurance.

However, interface journalists are concerned that although Tencent Video App does not guide other loan products in the "Finance" section, the carousel advertising space in the "Selected Columns" of its homepage often shows some small loan platform loan advertisements, and most of the loan products are provided by small loan companies, such as CYTS Jinfu Internet Microfinance Co., Ltd., Chongqing Zhonghong Microfinance Co., Ltd., Xi ‘an Xinghe Network Microfinance Co., Ltd. and Chongqing Pig Bajie Yichuang Microfinance Co., Ltd.

Photo: The advertising space in the "Selected" column of Tencent Video is a diversion for multiple lending platforms.

Interface journalists randomly tested one of the loan products pushed by the advertising space of Tencent Video App. After clicking the advertisement, they need to fill in information such as name, mobile phone number and mobile phone verification code, and check whether there are options such as housing, commercial insurance, social security, full car, provident fund and corporate tax payment. Soon after clicking "Apply for a loan", it will help the staff of the loan company to call, manually verify personal information, and push the information filled by the user to the cooperative bank, which will then.

Also as a video platform of the Internet giant, Ali’s Youku App is relatively "conservative" in financial business. Although there is a column of "My Finance" on the App, the related financial business is only the activities of opening cards and sending videos to members in cooperation with banks, such as opening electronic accounts in cooperation with Suzhou Bank and Agricultural Bank, and co-branded cards in cooperation with CITIC Bank and Huaxia Bank.

Third, the financial license blessing Tik Tok loan business, Aauto Quicker is also seeking to pay the license.

Among the two short video platforms, Tik Tok took the lead and Aauto Quicker was "ready to move".

At present, there are two loan products in Tik Tok Wallet, namely "DOU installment" and "safe borrowing", the former is similar to "flower shop" and the latter is similar to "borrowing shop".

The former focuses on "consumption before payment", which can be used in Tik Tok for live shopping, small shop shopping and purchasing "DOU+ popular" service. It can be divided into 3, 6 and 12 installments, with a maximum amount of 30,000; The latter is a consumer credit service product with annualized interest rate.(simple interest)It is 10.8% ~ 24%, and the maximum amount is 200,000.

Figure: Tik Tok’s "DOU installment" and "safe loan" credit products.

Behind the "DOU installment" and "safe lending", it is inseparable from the blessing of two financial licenses acquired by Tik Tok’s parent company ByteDance, namely the third-party payment license and the small loan license.

The third-party payment license is Wuhan Hezhong Yibao Technology Co., Ltd., which is wholly acquired, and the small loan license is Shenzhen Zhongrong Microfinance Co., Ltd.(hereinafter referred to as "Zhongrong Small Loan Company")Tik Tok’s two loan products are funded by Zhongrong Small Loan Company and its cooperative financial institutions.

According to the interface news, Zhongrong Small Loan Company has recently increased its capital to 5 billion yuan, and its legal representative, chairman and general manager have all been changed to Ding Boxun. Ding Boxun previously worked in ByteDance’s "Finance-Consumer Finance" business department. Although there is no direct relationship between ByteDance and Zhongrong Small Loan Company in terms of ownership structure, in April 2020, Zhongrong Small Loan pledged its equity to Shenzhen Today Headline Technology Co., Ltd.. At the same time, the mailbox of Zhongrong Small Loan Company was changed to ic-report@bytedance.com, the official mailbox of ByteDance.

In order to increase the scale of users who pay in Tik Tok, Tik Tok Wallet recently launched the activity of "Tik Tok Pay Binding Bank Card to Send Shopping Coupons", with the coupon amount ranging from 5 yuan to 11.8 yuan.

It can be seen that ByteDance’s payment and small loan licenses are more helpful to Tik Tok’s own e-commerce and local life, and its insurance brokerage and securities investment licenses have not been seen yet.

Although Aauto Quicker launched the "Aauto Quicker Wallet" earlier, it has not yet directly laid out its financial business. However, for the acquisition of financial licenses, Aauto Quicker is also "ready to move".

According to Tianyancha data, on August 31st, 2020, Aauto Quicker applied to register the trademark of "Laotie Payment" through its Beijing Dajia Internet Information Technology Co., Ltd..

In November of the same year, some media quoted people familiar with the matter as saying that Aauto Quicker indirectly obtained a payment license by acquiring a licensed payment institution, Yilian Payment. On the way of acquisition, Aauto Quicker acquired Yilian in the form of cash and shares, of which cash is about 300 million RMB, and the amount and value of shares are unknown. After the acquisition, Aauto Quicker will hold more than 50% of the shares and become the largest controlling shareholder of E-link Payment.

Regarding the acquisition of payment license, Aauto Quicker disclosed in the prospectus in January this year: "Aauto Quicker signed an agreement in August 2020 to acquire 100% equity of a payment company with an initial consideration of RMB 850 million in cash. As of the date of this report, the acquisition has not been completed. "

Interface journalists inquired about the national enterprise credit publicity information system and learned that at present, the only shareholder of Yilian Payment is Yilian Financial Control Information Co., Ltd., and the control rights of related companies have not changed hands.

Fourth, the risk of consumer privacy disclosure is high, and personal information is "disconnected" or opened.

According to the data released by Trustdata, a third-party data platform, in May 2021, the monthly active users of vibrato short videos.（MAU）About 453 million, Aauto Quicker MAU is about 268 million, iQiyi MAU is about 229 million, Tencent video MAU is about 172 million, and Youku MAU is 73 million.

"It is normal to generate finance based on traffic, but(both)It is really necessary to separate them. If they are mixed together, it may harm consumers’ interests and personal privacy will be violated. Li Yang, chairman of the National Finance and Development Laboratory, mentioned it at Caixin Summit.

An employee of the head small loan company who did not want to be named told the interface journalist.Some small and medium-sized lending platforms guided by video apps are not very formal, which may easily lead to the disclosure of personal information.Among them, some platforms will "package" the personal information filled in by users and sell it to third parties in pursuit of benefits. As long as a user has applied for a loan on a lending platform, the marketing calls and text messages of other lending platforms will be bombarded one after another, causing troubles to users.

Interface journalists have tested a number of mainstream loan apps in May, and they still receive harassment from marketing messages and phone calls. The tested lending platforms will call from time to time to induce journalists to borrow money from the platform in the name of issuing interest-free coupons and "reserving loan quotas".

In addition to receiving phone calls and text messages that have tested the App, the reporter also received some App text messages that have never been tested, including enjoying borrowing, paying back, patting and lending, and saving money.(See the report for details:After "collective makeup removal for mainstream loan App", it was bombarded by marketing. Who leaked my personal information? 》)

It is worth mentioning that the phenomenon of personal information being leaked in Internet platform lending has also attracted regulatory attention.

The interface journalist learned from the industry that the Credit Bureau of the People’s Bank of China recently issued a notice to a number of major online platform institutions, requiring these online platform institutions not to directly provide information voluntarily submitted by individuals, information generated in the platform or information obtained from outside to financial institutions in the name of application information, identity information, basic information and personal portrait scoring information.

In the notice, the requirement for the new business cooperation process after rectification is "platform-credit reporting agency-financial institution", which the industry calls "disconnected direct connection" of personal information.

In this regard, Su Xiaorui, an expert in financial science and technology, said that this can be regarded as an overall arrangement of the collection, processing and processing of personal information for loan assistance and joint loan business, emphasizing that such businesses should be put under the overall framework of personal credit reporting business management and rectified according to the business cooperation process of "platform-credit reporting agency-financial institution".

Su Xiaorui said,In the traditional mode, users are first acquired by platform institutions by virtue of their own traffic advantages or intelligent marketing means, and users fill in registration information on the page of platform institutions or the joint page of platform institutions and financial institutions, thus retaining user information and generating data value.

Measures for the Administration of Credit Information Business(Draft for Comment)It has been proposed that the use of credit information to make portraits and evaluations of individuals and enterprises is recognized as credit information business; Article 7 of the Regulations on the Administration of Credit Information Industry promulgated by the State Council clearly stipulates that no unit or individual may engage in personal credit information business without the approval of the supervision and administration department of credit information industry in the State Council; Therefore, this rectification has released a signal to the market, that is, the personal credit investigation business needs to be licensed.

Regarding the impact of this regulatory action, Su Xiaorui predicted that after this regulatory action, a formal document will be issued to systematically and comprehensively standardize the basic processes and cooperation modes of personal information business involving loan assistance and joint loan. She also predicted that,There will be more platform institutions seeking personal credit information licenses.

In addition to the risk of personal information disclosure, there are other hidden dangers in the lending business of video App.

On Internet complaint platforms such as black cat complaints, many users have reported that there are some problems in the lending function of some video apps, such as false propaganda, inducing lending with low interest rates, and bundling insurance with loans.

An Aiqiyi Xiaoye loan user complained that he borrowed more than 5,000 yuan on the platform because of the "7-day interest-free coupon" issued by the Aiqiyi App "Welfare Center", but found that there was no interest reduction when he repaid it two days later. After many complaints, Aiqiyi customer service pushed the responsibility to the lending institution and asked the user to go to the lending platform to complain.

"I borrowed 5,000 yuan from Xiaoya Loan and repaid it in 11 installments. When I first repaid it, I found that I was forced to buy insurance. At the beginning of the loan, I didn’t tell you that I needed to charge premiums." Another user of Xiaoya Loan reported that the first installment required repayment of the principal of 445.19 yuan, interest of 24.31 yuan, and the item of premium of 71.37 yuan, and the total premium of 11 installments was close to that of 800 yuan.

In addition, many users of Tik Tok "Relieved Borrowing" reported that after the loan expired, there was no "repayment entrance" in Tik Tok, and these complaints were still displayed as "being processed".

Machine heart report

Editor: Chen Ping, Du Wei

Have you ever seen a drone that can withstand a strong gust? Researchers at the California Institute of Technology use deep neural networks to make drones no longer afraid of the wind.

When the wind is strong enough to blow out the umbrella, the drone is steady, like this:

Flying against the wind is a part of air flight. On a large scale, when pilots land their planes, the wind speed may bring them challenges. On a small scale, gusts will also affect the flight of drones.

At present, drones either fly under controlled conditions and have no wind; Or operated by humans using a remote control. Unmanned aerial vehicles are controlled by researchers to fly in formation in the open sky, but these flights are usually carried out under ideal conditions and environments.

However, in order for UAVs to perform necessary but daily tasks autonomously, such as delivering packages, UAVs must be able to adapt to wind conditions in real time.

In order to make the UAV have better maneuverability when flying in the wind, a group of engineers from California Institute of Technology developed a deep neural network Neural-Fly, an artificial intelligence tool, which can keep the UAV agile in windy conditions, and only need to update some key parameters to help the UAV cope with new and unknown wind conditions in real time.

At the beginning of the article, we have seen the wind resistance of the UAV. The following shows a quadrotor UAV. With the help of the tool developed by this research, it can complete the figure-eight shuttle operation when the wind speed reaches 27 mph:

Watch the drone flying against the wind from another angle;

In order to allow the UAV to shuttle in various wind speeds, data is essential. This research needs little data. After obtaining the flight data in just 12 minutes, the automatic quadrotor UAV equipped with Neural-Fly learned how to respond to strong winds. "The amount of data used is very small," said Michael O’Connell, a graduate student in the Department of Aeronautics and Astronautics at California Institute of Technology and one of the authors of the paper.

The study was published in the journal Science Robotics on Wednesday.

Address: https://www.science.org/doi/10.1126/scirobotics.abm6597.

ArXiv Address: https://arxiv.org/pdf/2205.06908.pdf

In the Neural-Fly experimental training, the UAV flies in the wind tunnel with six different wind speeds, the fastest of which is 13.4 mph.

Based on these data, the team created a deep neural network, and then enabled their aircraft to skillfully maneuver in the same wind tunnel, such as enlarging the gate in a figure-of-eight pattern or cruising through two oval gates. The speed of the drone in the test is faster than it encountered in the training: about 27 miles per hour. This is the maximum wind speed that the wind tunnel can produce, pointed out Shi Guanya, the author of this paper and a graduate student of California Institute of Technology. Except that only a small amount of data is needed, the software only runs on Raspberry Pi, which is a cheap computing device.

Soon-Jo Chung, a professor of aerospace, control and dynamics systems at California Institute of Technology and a correspondent, said that the error rate they saw was 2.5 to 4 times better than that of the existing SOTA technology.

The picture below shows Shi Guanya, Soon-Jo Chung and Michael O’Connell from left to right. Congratulations, Shi Guanya will join the Robotics Institute of Computer College of Carnegie Mellon University as an assistant professor in September 2023.

The researchers said that this technology will be used for drone express delivery or flying cars in the future.

Overview of Neural-Fly technology

If unmanned aerial vehicle (UAV) wants to realize continuous commercialization, it is very important to perform safe and accurate flight maneuvers in dynamic high-speed wind. However, because the relationship between different wind conditions and their influence on the maneuverability of UAV have not been deeply studied, it is challenging to design an efficient robot controller using traditional control design methods.

"Neural-Fly" proposed by researchers of California Institute of Technology is a data-driven method. As a trajectory tracking controller based on deep learning, it can learn to adapt to rapidly changing wind conditions. Figure 3(A) below shows the data collection process; 3(B) When the wind speed is 13.3km/h (3.7m/s), input and label the training data; 3(C) is the distribution of input data and label data under different wind conditions.

On-line Adaptive+Off-line Meta-learning

Figure 2 below is an overview of the Neural-Fly method, which shows that it has made progress in adaptive flight control and robot control based on deep learning. Under the dynamic wind conditions of standard UAV, Neural-Fly can track the centimeter-level position error of flexible and challenging trajectory. Specifically, this method mainly consists of two parts, namely, offline learning stage and online adaptive control stage for real-time online learning.

For the off-line learning stage, the researchers developed Domain Adversarial Invariant Meta-learning (DAML), which learned the expression of deep neural network (DNN) which is independent of wind conditions in a data-efficient way. This representation adapts to different wind conditions by updating the linear coefficients of a set of mixed depth neural network outputs.

DAIML also has data efficiency, and only 12 minutes of flight data under six different wind conditions are used to train the deep neural network. DAIML contains several key features, which can not only improve data efficiency, but also provide information by the downstream online adaptive control stage.

It is worth noting that DAIML uses spectral normalization to control the Lipschitz property of deep neural network, so as to improve the generalization ability of unknown data and provide closed-loop stability and robustness. In addition, DAIML also uses discriminant network to ensure that the learned representation is wind-invariant, and the wind-related information is only included in the linear coefficient that adapts to the online control stage.

For the on-line adaptive control stage, researchers developed a regularized compound adaptive control law, which is based on the basic understanding of how the learned representation interacts with the closed-loop control system and has strict theoretical support.

Specifically, the adaptive law uses the combination of position tracking error term and aerodynamic prediction error term to update the linear coefficient related to wind. This method effectively ensures the stability and rapid adaptation to any wind conditions and the robustness to imperfect learning. Although this adaptive control law can be used with many learned models, the accurate representation learned from DAIML is helpful to further improve the adaptive speed.

experimental result

As far as the effect of Neural-Fly is concerned, it is 66% higher than that of nonlinear tracking controller, 42% higher than that of L_1 adaptive controller and 35% higher than that of incremental nonlinear dynamic inversion (INDI) controller. All these results are achieved by using standard quadrotor UAV hardware, and the default attitude control of PX4 is running at the same time.

The tracking performance of Neural-Fly is competitive even compared with related work without external wind interference and using more complicated hardware (such as on-board optical sensor that needs 10 times control frequency and uses DC motor speed feedback).

Table 1 below shows the error tracking statistics of different methods under different wind conditions.

The researchers compared Neural-Fly with two variants, namely Neural-Fly-Transfer and Neural-Fly-Constant. Among them, NF-Transfer uses representations trained from data of different UAVs, while NF-Constant only uses adaptive control laws with trivial non-learning basis.

Neural-Fly-Transfer shows the robustness to UAV configuration changes and model mismatch. NF-Constant, L_1 and INDI methods all directly adapt to unknown dynamics without assuming the underlying physical structure, and they have similar performance.

Finally, the researcher proves that Neural-Fly can realize a series of functions, allowing the UAV to follow the trajectory and fly over the low-altitude door quickly under the condition of strong wind, as shown in Figure 1 below.

　　Fengyun no.4 b star

　　Three characteristics to upgrade meteorological service

　　After the launch, Fengyun-4 B star was fixed at 123.5 degrees east longitude, and joined hands with Fengyun-4 A star. The observation range reached the Indian Ocean in the west and crossed the international date line of the Pacific Ocean in the east, which not only completely covered China’s territory, but also covered a wider area such as the Northwest Pacific Ocean and Oceania, enabling China’s second-generation geostationary meteorological satellite to realize the business model of two-star operation and east-west layout.

　　Fengyun-4 B-star service will be upgraded on the basis of A-star, and a high-speed, reliable, all-weather and all-weather data processing, transmission and distribution system will be built to ensure the meteorological service of meteorological data end users and serve the national economy and people’s livelihood.

　　Fast: every second will ensure efficiency.

　　As a geostationary meteorological satellite, obtaining high time resolution observation data is the primary task of Fengyun-4 B satellite, and data processing, transmission and distribution are irreplaceable links. Therefore, as the overall unit of the satellite, 509 Institute of the Eighth Academy of Aerospace Science and Technology Group, together with users and contractors, has built a high-speed data processing, transmission and distribution system between the satellite and the ground. Using the satellite-ground high-speed data system, the B-satellite remote sensing load is sent to the earth data transmission subsystem for data processing while acquiring remote sensing data, and then transmitted to the ground station for data processing through the satellite-ground high-speed data transmission channel.

　　After being processed by the ground station, the generated meteorological products will be quickly distributed to the fixed meteorological stations at all levels in provinces, cities and counties and the vehicle-borne and ship-borne mobile receiving terminals in the satellite coverage area through the high-speed information forwarding channel and the low-speed information forwarding channel of the satellite-to-ground forwarding system. Using the satellite-ground high-speed data system, it takes only a few minutes to obtain remote sensing data from remote sensing load to reach the end users, and it can provide high-frequency meteorological data for ships in China and its surrounding areas and sea areas.

　　Accurate: data "express" to ensure quality

　　Meteorological satellites are called "the first line of defense for disaster prevention and mitigation" by the industry because the remote sensing data detected by satellites are the first-hand data for monitoring and predicting the development and trend of severe weather. Therefore, satellite remote sensing data when bad weather occurs is particularly important.

　　By adopting a number of technologies, Fengyun-4 B-star ensures that data transmission is not afraid of typhoons and rainstorms, and can be stably and reliably transmitted to ground stations, assisting meteorological units to make accurate weather forecasts and reducing the losses that bad weather may bring to national lives and property.

　　Reality: self-upgrading to protect people’s livelihood

　　In order to further improve the application efficiency of B-star as the first operational satellite of Fengyun-4 series, this time, the research team carried out a "self-upgrade" of the satellite-ground data transmission and distribution system, which really made users experience convenience and speed.

　　In order to further bring special vehicles, small and medium-sized ships and other mobile platforms into the service group of low-speed information forwarding channel, the output power of the downlink power amplifier of Fengyun-4 B-star low-speed information forwarding channel is doubled, and the antenna diameter of the ground receiving terminal is reduced by 0.3 times, which solves the problem that it is difficult to install receiving equipment on mobile platforms such as vehicles and small and medium-sized ships.

　　At the same time, in order to adapt to the application scenarios where the moving direction of mobile terminals such as vehicles and ships changes in real time, and improve the experience of data forwarding service, the research team changed the polarization direction of downlink microwave signals in the high-speed information forwarding channel and the low-speed information forwarding channel of the satellite-to-ground forwarding system from horizontal vertical double-line polarization to left-right rotation double-circle polarization, thus solving the problems of polarization isolation reduction and data reception error or interruption caused by the direction change of the receiving platform.

　　Fengyun-4 B-Star has also added a high-speed Ka-band high-speed original remote sensing data transmission channel, which supports the real-time transmission of high-speed remote sensing data to the ground when a typhoon or local disastrous weather area occurs, thus improving China’s emergency capabilities such as forecasting and monitoring disastrous weather and reducing the loss of life and property of the people of the country.
