This article is reproduced from WeChat WeChat official account’s "Taihe Industry Watch" (ID: taifangwu). The original article was first published on February 25, 2021 with the title "China Aero-Engine Breakthrough in All Sides", which does not represent the viewpoint of Outlook Think Tank.

Ren Zhengfei told a story: In the 1970s, British Rolls-Royce offered to sell their Spey engines to China, and were willing to sell military engines directly. The Chinese side in charge of the negotiation was overjoyed and wanted to pay tribute to the British scientists, but the British scientists said, "Thanks to the great inventions of China scientists". When China comes back, find out which scientist it is, Wu Zhonghua. Where is he? Raising pigs in Hubei. Then hurry back to Beijing to be the director of the Institute of Thermophysics.

This is a dramatic story, which was later proved to be somewhat different from reality. But what is certain is that,The three-dimensional flow technology of Spey engine is indeed based on the "three-dimensional flow theory of turbomachinery". In 1950, Wu Zhonghua read a paper at the annual meeting of the American Society of Mechanical Engineers in new york, and formally put forward this theory, which was later defined as "Wu’s general theory" and the basic equation in the theory was called "Wu’s equation". Wu Zhonghua’s lecture video was once used as a training material by NASA.

Ren Zhengfei felt that if we had followed Wu Zhonghua’s basic theory and made continuous breakthroughs in engineering technology, the situation of aero-engines in China today might be more optimistic.

In December 2020, the US Department of Commerce published a new list of "military end users", and 80% of the 58 China companies were related to aviation. This is not a sudden bad news. As early as the beginning of 2020, rumors of an embargo on commercial aircraft in China once triggered domestic concerns that the supply of C919 engines might be cut off. From beginning to end in 2020, the focus of American sniper will be China’s aviation industry, especially engines.

As the heart of an airplane, aero-engine is one of the most complicated engineering technologies of human beings so far.At present, many countries can build airplanes, but only the five permanent members of the United Nations, namely, the United States, Russia, Britain, France and China, can really independently develop aero-engines.

China’s aero-engine construction began in the 1950s, and it has gone through a tortuous road from imitation and improvement, to partial independent research and development, and then to completely independent research and development.

At the beginning of the 21st century, with the implementation of "two-engine special project" and the establishment of China Hangfa, the development of aero-engines in China began to enter the fast lane of catching up.In the direction of military aviation development, the self-developed "Taihang" series engines have been put into production in turn, gradually getting rid of import dependence. In the civil direction, CJ-1000A, the "Yangtze River" engine supporting C919, has entered the trial production stage, and CJ-2000 of 35-ton class has also achieved the ignition test of the core engine in 2020, and it is said that the first verification machine has been assembled.

Since the 1990s, China’s reflections and discussions on aero-engines have come and gone, and they have continued to this day. The problem has long been found, but the difficulty lies in how to solve it.

Taking the "two-aircraft special project" and the establishment of China Airlines as milestones,China has started a breakthrough from technological innovation to institutional innovation.

From "if there is nothing" to "cohesive development"

In 1958, Wu Daguan, known as the "father of aero-engines" in China, took the opportunity of visiting Britain and made a special trip to the Soviet Union on his way home. He wanted to ask the Ministry of Aviation Industry of the Soviet Union for verification.

After it was rumored that the Soviet Union successfully launched the world’s first artificial satellite, Khrushchev excitedly declared that planes would enter museums in the future.It means that with missile technology, airplanes are useless.. This argument spread to China, which triggered a heated debate at the decision-making level. At that time, China had copied the first turbojet engine turbojet -5 according to the Soviet BK-1φ in Shenyang Aero-Engine Factory, and the jet fighter J-5 with this engine also rushed into the blue sky in Shenyang Aircraft Factory.

Will we develop our own engine next? Fortunately, the ministers of the Soviet aviation industry reassured him: in war, although missiles have great lethality, they really have to rely on planes to conquer each other. Therefore, the United States has not stopped engaging in fighter planes, and our Soviet Union is still engaged in MIG -21.

In the early days of the founding of New China, its national strength was weak, so it could only give priority to the development of critical science and technology. In the debate on "giving priority to the development of aircraft or missiles", Qian Xuesen put forward the "Opinions on Establishing China’s National Defense Aviation Industry" to the Central Committee, advocating concentrating on the development of rockets and missiles.

After a series of investigations and discussions, the central government regards aerospace as a whole and focuses on breaking through missiles and rockets first.In the end, "two bombs and one satellite" laid the foundation of China’s international status and security, and also proved Qian Xuesen’s vision.

In February 1956, Qian Xuesen submitted to the Central Committee "Opinions on Establishing China’s National Defense Aviation Industry"

However, for a long time after the breakthrough of rocket technology, there was no overall planning for the development of aviation industry, which led to the lack of strategic traction in the independent research and development of aircraft, especially aero-engines.

Political circles are still debating whether the aviation industry belongs to high and new technology. Until 1995, when the Ninth Five-Year Plan was released, aviation technology was still not included in high and new technology. Many scientists began to worry. Seven respected and old experts, including Wang Daheng and Shi Changxu, signed a letter to state leaders to express their feelings.

Experts put forward two reasons for vigorously developing aviation technology: First, the Gulf War proved that air power still plays a decisive role in modern wars; Second, the development of aviation industry plays an obvious role in driving the national economy.Experts believe that the gap between China’s aviation technology and advanced countries is widening day by day. If it is not developed vigorously, there will not only be a military crisis, but also the huge domestic civil aviation market will be occupied by foreigners in the future.

For aero-engines, Academician Wang Daheng, the winner of the medal of "two bombs and one satellite", used the word "free" to describe it. Free does not mean nothing, but it is sometimes absent and looming.

"Free" means insufficient investment.China’s first self-designed turbofan -6 with large thrust engine lasted for 20 years, with a total development cost of 150 million RMB, and only 2 million RMB was available in two years at the critical stage of development. At the same time, it cost about $2 billion to develop an engine for an ordinary large and medium-sized aircraft in the United States.

In the 1980s, the United States successively put forward pre-research projects such as IHPTET (Integrated High Performance Turbine Engine Program) and VAATE (Advanced Turbine Engine Program), and invested 5 billion and 3.7 billion US dollars respectively. China also put forward two pre-research plans for high-performance engines in the 1980s, but the total investment in 20 years is only equivalent to that of the United States in one quarter. Even if the purchasing power of money in the same period is taken into account, the gap between them is huge.

Aeroengine pre-research program in the United States

It was not until more than half a century passed that we had a deeper understanding of the strategic value and complexity of aero-engines. Since 2011, the Ministry of Industry and Information Technology has taken the lead in investigating and demonstrating aero-engines and gas turbines. In 2012, the "two-machine special project" was approved. In March 2016, in the 13th Five-Year National Science and Technology Innovation Plan issued by the State Council, aero-engines and gas turbines ranked first.

The implementation of the "two-engine special project" means that aero-engines as a major national strategic project will receive strong support from policies, funds and resources at present and in the future, and fundamentally solve the problem of insufficient investment.

By the end of 2020, the investment in the "two-machine special project" has reached 300 billion yuan. With the strong support of policies and funds, China’s aero-engine and gas turbine technology is accelerating to catch up with the world’s advanced level and achieve a historic leap.

From "Aircraft Dependence" to "Flight Separation"

"There are no planes, what do you need an engine for?"

In 1982, due to the changes in the equipment system of the National Air Force, the J -9 and J -6 planes were planned to be dismounted one after another. As its supporting power, the turbofan -6 engine is also facing dismounting because it suddenly loses its applicable object, and at this time, the turbofan -6 has gone through.18 years of hard development, just passed the 24-hour pre-flight test run. From the beginning of scheme research in 1964 to the end of development in 1984, turbofan -6 lasted for 20 years, which almost condensed the youth of a generation. According to the relevant personnel’s memories afterwards:

"At the moment when the suspension of development was announced, Wu Daguan burst into tears, and he also cried on stage."

The development was terminated due to the dismounting of the plane, and the turbofan -8 was developed by Shanghai Changzheng Machinery Factory. This large thrust civil aviation engine, which was born for Yun -10 aircraft, was successfully tested on Boeing 707 for more than a dozen times, and flew to Lhasa and other places as the heart of Yun -10. The cumulative flight time was 170 hours, and all the performances met the design standards. In 1985, Klebos, vice president of the General Aviation Engine Division of the United States, visited China and once admired the turbofan -8:

It was indeed a great achievement that you could finish such a complicated engine 10 years ago.

Turbofan -8 stopped production with Yun -10 dismounted.

Frequent dismounting of projects not only discourages the enthusiasm of researchers, but also delays the development opportunity.For a long time, the development path of aero-engines in China was "maintenance-mapping imitation-model improvement-model development-pre-research", which was basically the opposite of the path in the United States. At that time, the United States had established a mature pre-research mechanism and took a steady route of "technical pre-research-core machine-test verification".

In 2001, Wu Daguan pointed out in his article Reflections on Two Major Historical Issues of Aviation Industry,The policy of "scientific research first, power first" formulated by the aviation industry has not been agreed and implemented, and in fact it has become a general slogan.

One of the fundamental reasons why the pre-research could not be carried out was that the development of the engine was subordinate to the aircraft at that time, that is, "one factory, one model". If a factory wants to develop an airplane, there will be a research institute to develop a matching engine.The engine followed the plane, the plane project dismounted, and the engine development stopped.

On the other hand, due to the long-term lack of technical reserves and pre-research, the development cycle of aero-engine is much longer than that of aircraft, and aircraft often can’t afford to wait for the engine, so it is better to buy others’ ready-made products for independent development. Academician Liu Daxiang, an aviation power expert, once reflected on this issue:

"For a long time, too much emphasis has been placed on aircraft with engines and models with pre-research, and insufficient attention has been paid to early technical verification. Many key technologies have not been effectively broken before model establishment, and often model development is synchronized with technical research and component troubleshooting, resulting in repeated model development, which greatly delays the development cycle."

Under the collective reflection of aviation industry experts, the call for "separation of flight and development" continues to rise. In 2009, China Hangfa Commercial Aviation Engine Co., Ltd. (hereinafter referred to as "China Hangfa Commercial Engine") was established, becoming the general contractor of China’s large passenger aircraft engine project, and began to develop China civil aviation engine.

In 2016, China Aviation Engine Group Co., Ltd. (hereinafter referred to as "China Hangfa") was formally established, which was jointly funded by SASAC, Beijing State-owned Capital Management Center, China Aviation Industry Corporation and China Commercial Aircraft Corporation.

Since then, China has owned a national specialized aero-engine enterprise group.It means that, at least institutionally, aviation development has completely got rid of the dependence on aircraft development., towards the independent development of the sea of stars.

From "Imitation of Surveying and Mapping" to "Independent Research and Development"

"Buy if you can, and copy if you can’t."

The background of Ren Zhengfei’s story is the 1970s. In fact, the introduction of "Spey" engine from Britain was just an accidental episode. In the early days, most aero-engines in China came from mapping and imitation of Soviet engines. As the core technology of aviation industry, the western countries have always adopted a blockade strategy against China. After the Soviet Union cut off aid, China’s aviation industry once fell into a dilemma of no availability. In 1972, British Rolls-Royce offered to provide Spey MK202 engine to China, and at the same time transferred technology, which was quite unexpected.

Spey MK202 engine

In December 1975, China and Britain signed a purchase contract of about 77 million pounds.The original plan is divided into two steps. It will take three years to learn how to assemble qualified Speer with imported parts, and then five years to realize localization.. In 1980, the Spey engine developed and assembled according to British wool was tested in Britain. However, in the national economic adjustment in the 1980s, it faced the same reality as turbofan -6, so the localization process was suspended for more than ten years.

It lasted for 30 years before and after the localization of Spey, which is very emotional. Because we couldn’t wait for the engine, in order to ensure the production of the aircraft, we first used the Spey engines stored for 20 years, and then bought a batch of second-hand engines from Britain. Until around 2010, turbofan -9 finally kept up with the progress and realized continuous mass production supply.

The turbofan -9 "Qinling" engine developed from Sibei belongs to "partially independent design". Before that, most of us were "copying and improving" Soviet engines.Long-term measurement and imitation lead to the fact that the technical ability of the institute is even inferior to that of the factory, and the technology cannot be digested and its own research and development system cannot be formed.

It was not until 2002 that the domestic turbojet -14 "Kunlun" engine was finalized that China completed the whole process of self-development for the first time.

In December 2005, the domestic turbofan -10 "Taihang" developed by Shenyang Liming Engine Company passed the life test and became the first large thrust turbofan engine with independent intellectual property rights in China. "Taihang" took 27 years from the pre-research in 1978 to the project establishment in 1987, and then to the completion of the design finalization examination at the end of December 2005. This process can be said to be stumbling, and even the explosion of the testing machine occurred.

Until 2011, the maximum afterburner thrust of turbofan -10 was determined to be 125KN, which means that this "domestic heart" with high hopes has finally entered the mass production state. "Taihang" has finally passed the stage of being criticized by netizens as "not very good", and its performance in recent years can be regarded as disappointing. Up to now, no fighter plane carrying "Taihang" has crashed due to engine failure.

From imitation and improvement, to partial independent research and development, and then to having independent intellectual property rights, China aviation industry people clearly realize that key areas must be self-reliant and core technologies must be mastered by themselves.However, as the most complex industrial field of mankind, the development of aero-engines cannot be done behind closed doors.

The development of turbofan -10 has also learned from others’ strengths. For example, the core engine principle draws lessons from the F-110 commonly used in the United States. In order to meet the actual domestic installation demand, Su -27 was introduced as a flight test platform, and a lot of technical experience of the supporting power system AL-31F of Su -27 was digested and absorbed. Like many domestic equipment technologies in China at present, turbofan -10 does not copy Russian products or blindly follow hairdressing, but absorbs the experience of the United States and Russia at the same time, and then explores a technical route that conforms to China’s reality.

Main military aero-engine models developed in China.

From "filling in the blanks" to "looking back", it is not easy to finally ensure that it is "neck and neck" with developed countries.After the establishment of China Hangfa, a "three-step" road map was established.

The first step is to narrow the gap with the advanced level of foreign aero-engines, initially establish an independent innovation research and development system for aero-engines, and lay a foundation for development;

The second step is to basically build an independent innovation research and development system for aero-engines;

The third step is to complete the independent development process of representative models, build the basic research, product development and industrial system of independent innovation, basically realize the strategic transformation of independent innovation and development, and make China Hangfa an innovative enterprise with international competitiveness.

From "Closed Independence" to "Open Integration"

"Small core, great collaboration, specialization and openness."

In the first half century, the development of aero-engines in China was not smooth. From the 1990s to the beginning of this century, there were many reflections on the lagging development of aero-engines in China.The old experts concluded that "our understanding of the development law of aviation technology is insufficient, and we lack long-term planning and stable planning", but the deeper reason lies in the system.

The American military industry model is based on enterprises.Boeing, Loma, Nuoge and other dual-use groups are the main manufacturers, Raytheon, Holwell, Pratt & Whitney, General Motors and other groups provide sub-system support for them, and thousands of dual-use enterprises such as TI and ADI are responsible for supplying materials and parts, forming a pyramid-shaped integration of defense and civilian technologies ecological circle with open cooperation, step-by-step competition and professional subdivision.

During the Cold War, the United States once supported two aviation giants, GE and PW, through the horizontal competition mechanism controlled by the government. In 1968, the US Department of Defense asked Pratt & Whitney and GM to manufacture and test one engine each. This government-led "selecting the best to help the strong" has achieved remarkable results, and finally achieved the famous GM F-110 engine and Pratt & Whitney F-100 engine.

F110-GE engine

Pratt & Whitney initially won the competition and signed the contract first. Although GM was at a disadvantage in the initial competition, it subsequently launched an improved F110-GE-129, and Pratt & Whitney developed an improved F100-PW-229 to compete with it.

In February, 1984, the United States Air Force purchased F100 and F110 in proportion according to the double contractor procurement strategy, and basically they were exposed to rain and dew. It is under such a "horse racing" mechanism and order support that the two companies have grown into the world’s top aero-engine companies.

For a long time, China’s military industrial model is dominated by military industrial groups with strong administrative color, and scientific research tasks are coordinated, coordinated and protected in a highly planned way. The general research institute to the assembly plant, and the supporting research institute to the supporting plant are mostlyIn the state of "vertical cooperation and fragmentation", military and civilian lines are separated, forming a closed monopoly system with separation of research and development, lack of competition and self-protection.

The establishment of the "Two-Aircraft Project" and China Aviation Development Co., Ltd. is escorted by the in-depth promotion of the national integration of defense and civilian technologies strategy. In 2016, the Opinions on the Integrated Development of Economic Construction and National Defense Construction issued by the Central Committee of the Communist Party of China, the State Council and the Central Military Commission clearly proposed to deepen the reform of the national defense science, technology and industry system, further break the industry closure, expand the introduction of social capital, highlight core capabilities, liberalize general capabilities, promote socialized cooperation, and promote the professional reorganization of military enterprises.

Breaking the binary separation of military and civilian and promoting open integration are not only institutional breakthroughs, but also the reshaping and integration of the industrial chain.Taking the aviation industry as an example, the "main manufacturer-supplier" model that the United States has been pursuing is being followed by global aviation manufacturing enterprises. In this mode, the development of an aircraft requires the early intervention of suppliers and joint participation in research and development.

The main manufacturer splits its subordinate manufacturing units and becomes a system integrated manufacturing role, getting rid of the "heavy-load" link of "manufacturing production", which requires high load to produce benefits, and enhancing its ability to cope with market changes; Suppliers can focus on the research and development and technical strength reserve of a certain subsystem, so as to be more professional and efficient.

As the core system of an aircraft, aero-engine open cooperation can also greatly improve the development efficiency. For example, since 2004, Rolls-Royce Company has only produced 30% of the core components and the highest added value, and subcontracted the remaining 70%, thus reducing the manufacturing and purchasing costs of all engine parts as much as possible under the premise of controllable risks.

On this basis, China Hangfa has further determined the development mode of "small core, large cooperation, specialization and openness", which means that the development of China aero-engine can attract more extensive external forces to participate in the cooperation nationwide and even globally, and enterprises can concentrate on improving key core capabilities. According to the disclosed information, there are currently more than 350 suppliers participating in the "Yangtze River" series of engines, initially forming a global supply chain. At the same time, 69 suppliers from 16 countries are willing to participate in the commercial engine project in China.

Historical lessons have proved that you can’t build an engine behind closed doors.

Aeroengine is composed of tens of thousands of precision parts, which has a long development cycle and involves a wide range of fields. Independent research and development of aero-engines is an arduous challenge to the current basic disciplines, design, materials and technology. China has a complete range of manufacturing industries and abundant resources, but the support provided by basic industries is far from enough. Through open integration, the standards and data barriers in the upstream industrial chain (such as materials, machining, measurement and testing, etc.) can accelerate the integration of manufacturing resources, enrich and improve the industrial chain, and maximize the cost reduction and efficiency improvement of the whole industry.

Due to the historical debts and the current technical blockade, it is doomed that the breakthrough road of China aero-engine is still bumpy, which requires great determination, patience and wisdom. But the first light on this road has shown us the way.

Assumption of maritime cooperation in the construction of "Belt and Road"

  Xinhua News Agency, Beijing, June 20th Assumption of maritime cooperation in the construction of "Belt and Road"

  In 2013, the Supreme Leader of president, China successively put forward major initiatives to jointly build the Silk Road Economic Belt and the 21st Century Maritime Silk Road. In 2015, the China Municipal Government issued "Vision and Action for Promoting the Joint Construction of the Silk Road Economic Belt and the 21st Century Maritime Silk Road", which put forward that policy communication, facilities connectivity, smooth trade, capital financing and people’s hearts should be the main contents, adhere to the principles of mutual consultation, joint construction and sharing, and actively promote the construction of the "Belt and Road", which has received extensive attention and positive response from the international community.

  In order to further strengthen strategic docking and joint action with countries along the route, promote the establishment of an all-round, multi-level and wide-ranging blue partnership, protect and sustainably utilize the oceans and marine resources, realize the harmony and common development of the people and the sea, jointly enhance the well-being of the oceans, and jointly build and prosper the Maritime Silk Road in the 21st century, the National Development and Reform Commission and the State Oceanic Administration have specially formulated and issued the "Assumption of Maritime Cooperation on the Belt and Road".

  I. Background of the Times

  The ocean is the largest ecosystem on the earth, a common space and precious wealth for human survival and sustainable development. With the further development of economic globalization and regional economic integration, the cooperation in market, technology and information with the ocean as the carrier and link has become increasingly close, and the development of blue economy has gradually become an international consensus, and an era of paying more attention to and relying on maritime cooperation and development has arrived. "Walking alone is fast, and many people travel far". Strengthening maritime cooperation conforms to the world development trend and the general trend of open cooperation. It is an inevitable choice to promote closer economic ties, deeper mutually beneficial cooperation and broader development space for all countries in the world. It is also an important way for all countries in the world to jointly meet the crisis challenges and promote regional peace and stability.

  Adhering to the Silk Road spirit of peaceful cooperation, openness, tolerance, mutual learning and mutual benefit, China Government is committed to promoting the implementation of the 2030 Agenda for Sustainable Development formulated by the United Nations in the marine field, and is willing to carry out all-round and multi-field maritime cooperation with countries along the Maritime Silk Road in the 21st century, jointly create an open and inclusive cooperation platform, establish an active and pragmatic blue partnership, and cast a "blue engine" for sustainable development.

Analysis on Promoting the Reform of Housing Provident Fund and Reform Options

  ■ Zheng Bingwen
  
  The issue of housing provident fund retention and abolition has once again become a hot topic in society. Some people think that the housing provident fund system is unfair, and the housing provident fund has completed its historical mission. In order to reduce the burden on enterprises, it is advocated to abolish the housing provident fund.
  
  The author believes that the housing provident fund system still has the value of existence at present and should continue to be retained.
  
  Institutional Efficiency and Equity of Housing Provident Fund
  
  From the 2018 Annual Report of National Housing Provident Fund published by official website, Ministry of Housing and Urban-Rural Development, we can have a bird’s eye view of the institutional efficiency and fairness of housing provident fund, and have a general understanding of the system. According to the "annual report" of the provident fund, the institutional efficiency of the provident fund can be summarized into four characteristics, and the institutional fairness can be summarized into four characteristics. First look at the four institutional efficiency characteristics of housing provident fund.
  
  First, the benefit rate is relatively high.Since the establishment of the provident fund system, a total of 33.35 million individual housing loans (including two sets of loans with more than two times) have been issued, of which one third are dual employees, and a total of about 55 million people have benefited. Among the 144 million paid-in employees, 38% have successfully become housing lenders. The essence of the housing provident fund system is a mutual aid system. As a mutual aid system, 38% of its members can benefit, which is not low.
  
  Second, the mortgage level is appropriate and effective.In 2018, 2.53 million individual housing loans were issued, with an amount of 1.02 trillion yuan. On average, each mortgage was about 400,000 yuan. Paying down payment in second-and third-tier cities can basically solve the loan, and there is no need to combine commercial loans.
  
  Third, reduce the heavy interest burden for employees.The interest rate of provident fund loans is low, 3.25% for more than five years, which is 1.65&mdash lower than the benchmark interest rate of commercial individual housing loans; 2 percentage points. The mortgage issued in 2018 can save interest expenses of 202 billion yuan for loan employees, and the average loan can save interest expenses of 80,000 yuan if calculated in 10 years. For more than 20 years, the provident fund system has reduced the interest burden of trillions of yuan for employees, which is the vitality of the provident fund system.
  
  Fourth, the administrative cost comes entirely from the extracted management fee.There are 342 provident fund management centers in China with 3,439 service outlets, and there are 44,000 employees in the country, 40% of whom are non-employees. In 2018, the management fee was 11.7 billion yuan, and the comprehensive management cost per 100 million yuan of assets was 210,000 yuan, including salaries and bonuses of all employees, office space, office equipment and official expenses. The whole provident fund system is a self-supporting system. In the national contributory welfare system, such as the social insurance system and even the National Social Security Fund Council, all its operating and management costs (staff salaries and office equipment, etc.) come from financial funds, while the management costs of the housing provident fund system are completely self-digested, which is very rare in China’s current contributory welfare system.
  
  Let’s take a look at the four institutional fairness characteristics of the housing provident fund from the 2018 Annual Report of the National Housing Provident Fund.
  
  First, the coverage has gradually expanded.By 2018, the number of employees paid into the provident fund was 144 million, which is a large coverage in China’s contributory welfare system. For example, in a comparable social insurance system, except for medical care and old-age care, unemployment insurance covers 196 million people and maternity insurance covers 204 million people, and they are more compulsory than housing provident fund. Other payment systems cover a small number of people, for example, enterprise annuities cover less than 24 million people.
  
  Second, the structure of paid employees is dominated by formal sector employment.Among the 144 million employees, 31% are from government agencies and institutions, 20% from state-owned enterprises, 31% from private enterprises and 8% from foreign capital, and the remaining 10% are non-governmental, collective enterprises and other types of units. There are narrow and broad definitions of formal sector employment in China. The narrow definition refers to urban corporate institutions and urban collective units, which employ 170 million people. In a broad sense, we should also add 140 million urban private employees, that is, employees of private enterprises whose business address is located above Chengguan Town in the county. Unemployment insurance, industrial injury insurance and provident fund mainly cover employees in the formal sector in a narrow sense.
  
  Third, the system is very transparent.The information disclosure and transparency of the housing provident fund system have always been better. In 2015, the Ministry of Housing and Urban-Rural Development, the Ministry of Finance and the People’s Bank of China jointly issued the Notice on Improving the Information Disclosure System of Housing Provident Fund (J.J. [2015] No.26). In addition, the Annual Report of the National Housing Provident Fund jointly released by the Ministry of Housing and Urban-Rural Development, the Ministry of Finance and the Central Bank to the whole society every year has complete information and is very transparent. For example, the proportion of paid employees according to the nature of the unit (civil servants, institutions, state-owned enterprises, collective enterprises, etc.), the withdrawal of provident fund by type (reasons for withdrawal, number of people, proportional amount), various types of loans (housing type, area, number of units, etc.), pilot loans to support the construction of affordable housing, business revenue and expenditure and value-added income, distribution of housing loans and value-added income in various provinces, asset risk, etc.
  
  Fourthly, housing provident fund, as a mutual fund, has played three spillover effects on housing construction in China.One is to occupy a place in the housing market. For example, in 2018, the housing consumption category of housing provident fund, personal housing loans and discount loans for public developers totaled 2.2 trillion yuan (including nearly half of the repayment of loan principal and interest), accounting for 17% of the national commercial housing sales and 16% in the personal housing loan market. Another example is to support loan workers to purchase and build housing area of 287 million square meters, accounting for 19% of the national commercial housing sales area. Second, it plays an obvious role in the rental market and housing repair market. The provident fund has provided support to employees who have no need to buy a house for the time being in their needs of renting and repairing houses. The withdrawal amount of 7.66 million rented employees has reached 73 billion yuan, and the per capita annual withdrawal amount is 10,000 yuan. Third, it plays a huge role in the construction of affordable housing. The housing provident fund provides loan support for affordable housing construction projects. By the end of 2018, a total of 87.215 billion yuan of loans had been issued to 373 pilot projects for affordable housing construction. In addition, the value-added income of some housing accumulation funds also provided supplementary funds for the construction of urban public rental housing (low-rent housing), and a total of 336.5 billion yuan was withdrawn from the construction of public rental housing. For another example, the Beijing Housing Provident Fund has so far issued 36 project loans with a loan amount of 20.1 billion yuan and a construction area of 940,000 square meters, potentially solving the housing difficulties of low-and middle-income workers’ families by more than 90,000 households.
  
  The mission of housing provident fund is not completely over.
  
  From the perspectives of efficiency and fairness, the above-mentioned provident fund system has performed well in many contributory welfare systems, at least not very badly, which has played a role in the transformation of housing system and solving the housing difficulties of employees. In the coming period, the historical mission of housing provident fund has not yet ended, which is mainly manifested in the following aspects.
  
  First, from the demand side, housing provident fund can also play a certain role.In the third-and fourth-tier cities, the role of alleviating housing difficulties for working-class people is very obvious. The most convincing is the mortgage rate, that is, the ratio of the balance of personal housing loans to the balance of housing provident fund deposits at the end of the year. For example, most provinces in the central and western regions have mortgage rates of 70% to 80%, and only Xizang (68%), Qinghai (69%) and Xinjiang Construction Corps (38%) are below 70%. Almost all first-and second-tier cities are above 85%, for example, Beijing is 95%, Shanghai is 96%, Tianjin is almost 100%, and Jiangsu, Zhejiang, Anhui, Fujian and Guizhou are above 95%. What’s important is that the housing prices in first-and second-tier cities are high, and the employees employed by government agencies and institutions every year are under great pressure to buy houses. These groups are all admitted through the "national examination", and they undertake the function of running the state machine. In the front line of scientific research and teaching, the marginal utility of housing provident fund is the highest, and in second-and third-tier cities, they can completely rely on provident fund to solve the problem of buying houses. If the provident fund is abolished, it means that there are great obstacles for the central ministries or some departments to recruit outstanding talents.
  
  Second, from the pattern of initial income distribution in China, retaining the provident fund can increase the share of labor income.As we all know, the share of labor income is too low in China’s primary income distribution pattern. Since the reform and opening up, the index of labor income share has fluctuated, from over 60% in the 1990s to below 50% before the international financial crisis in 2008, and then it has rebounded. It has improved in the past 10 years, but it is 15 to 20 percentage points lower than developed countries on average, and even lower than some developing countries.
  
  The report of the 19th National Congress of the Communist Party of China clearly pointed out: "Adhere to the simultaneous growth of residents’ income while economic growth, and realize the simultaneous increase of labor remuneration while improving labor productivity". The Opinions of the Central Committee of the Communist Party of China and the State Council on Accelerating the Improvement of the Socialist Market Economic System in the New Era just released on May 18, 2020 once again pointed out: "Increase the labor remuneration of workers, especially front-line workers, increase the proportion of labor remuneration in the initial distribution, realize the simultaneous growth of residents’ income while economic growth, and realize the simultaneous increase of labor remuneration while improving labor productivity."
  
  From the perspective of implementing the central spirit, the provident fund system is a good thing. The idea of canceling the provident fund is mainly for the sake of reducing the burden on enterprises, and the starting point is also good, but the crux of the problem lies in the fact that the focus should be on reducing taxes and social security premiums. China’s tax revenue mainly comes from indirect taxes, and direct taxes only account for about 10%. In the long run, we should gradually focus on direct taxes, but if the share of labor income is always too low, it will always be empty talk.
  
  Third, from the perspective of employees’ sense of acquisition, the effect of provident fund is very obvious.When they paid the provident fund, the people never complained that the base was too high and the proportion was too high. They complained that the social security premium rate and base were too high. The phenomenon of "evasion" of social security for ordinary people and enterprises is very serious, while almost no one and enterprises "evade" the provident fund! Why? Because the "tax wedge" of the provident fund is "zero", 100% of it becomes the disposable income of employees and their families, and its private attribute is very obvious. Excluding the provident fund, the tax wedge of social security contributions (including payroll tax) in China is as high as 30.81%, which is exactly equal to the average of OECD countries. In contrast, the tax wedge of Denmark, a Nordic welfare country, is only 30.99%, which is only a little higher than that of China. There are many developed countries with lower tax wedge than ours, such as Japan (29.64%), Australia (26.96%), Britain (26.51%), Luxembourg (26.29%), Ireland (24.66%), Canada (24.12%) and the United States (23.95%).
  
  Importantly, in the social security payment of individuals and enterprises, the tax wedge of enterprise payment is as high as 19.22%, and the tax wedge of individual payment and individual tax is 6.41% and 5.19% respectively. That is to say, in the structure of tax wedge, the social security payment of enterprises accounts for as high as 62.36% (individual payment is 20.79%, individual tax is 16.85%). Such a large tax wedge, with Of course, enterprises can evade fees "justifiably". Employees don’t get benefits, and they don’t have a sense of gain. Of course, they are willing to "cooperate" with enterprises to evade fees. Therefore, it is an unspoken rule that employees and enterprises "evade" social security fees together, and it is the social security system that ultimately "suffers". This is the main reason why paying provident fund is more popular than paying social security fees.
  
  Fourth, the low-and middle-income borrowers of the provident fund account for 95%, which is especially popular in poor areas.One of the main reasons for advocating the abolition of provident fund is that the system is unfair and the poor subsidize the rich. Of the 2.53 million mortgages of 1 trillion yuan issued in 2018, 95% were low-and middle-income borrowers, and high-income earners only accounted for 5%. According to the 2018 Annual Report of the National Housing Provident Fund, the low-middle income here means that the income is 3 times lower than the average wage of the local society last year, and the high income means that the income is 3 times higher than the average wage of the local society last year (inclusive). Look at age and housing purchase: 76% of borrowers are under 40 years old, 89% buy a building area of less than 144 square meters, and the first set accounts for 85%. Obviously, the above data show that buyers are basically just in need, and the provident fund system really provides protection and support for low-and middle-income groups to buy houses.
  
  Let’s use the deposit base of several typical poverty-stricken areas in 2017 to see their attitudes and behaviors towards the provident fund (the data are all from their housing provident fund report released in official website): the deposit base of Dingxi in Gansu is 101% of its social average wage, Baise in Guangxi is 110% of its social average wage, and Zhangye in Gansu has the highest actual deposit base, which is 113% of its social average wage. This shows that the deposit base of employees in poverty-stricken areas is very "real", even exceeding the local social wage, because they have benefited.
  
  Fifth, the number of employees who have paid in is increasing, especially in private enterprises.Let’s look at the fairness between "within the system" and "outside the system". In real life, this pair of concepts can be understood in two ways. One means that institutions and state-owned enterprises are regarded as "within the system", while others are regarded as "outside the system". Among the 144 million paid-in employees, there are 44.52 million in government institutions and 29.28 million in state-owned enterprises, totaling 73.8 million, which shows that the number of paid-in employees in the "system" is basically in a "saturated" state; Another understanding is that "within the system" refers to the formal employment sector, "outside the system" refers to the informal employment sector, and the formal employment sector has broad and narrow meanings. With government agencies, institutions and state-owned enterprises basically saturated, private enterprises will become the main force to participate in the provident fund at present and in the future. For example, in 2018, there were 19.9 million new accounts opened in the provident fund, of which private enterprises accounted for 50% (9.94 million), which shows that the proportion of private enterprises will gradually increase in the process of expanding coverage in the future. In the formal employment group, it is unfair to employees who have not participated in the provident fund, but the expansion of coverage needs a process. The state has issued documents many times to expand the coverage of the provident fund, which requires the joint efforts of employers, employees and the whole society, and the coverage of social insurance has also gone through such a process. For example,The basic old-age insurance for employees of urban enterprises covered only 136 million people 20 years ago, and reached 967 million in 2019. However, if the provident fund is abolished, the employees who have not joined and those who have joined will lose their opportunities forever. As long as this system exists, opportunities will exist.
  
  Main problems and reform suggestions of housing provident fund system
  
  The Opinions of the Central Committee of the Communist Party of China and the State Council on Accelerating the Improvement of the Socialist Market Economic System in the New Era, which was just released on March 18th, 2020, pointed out: "Reform the housing provident fund system".
  
  The author believes that this is the most authoritative and latest tone of the central government on housing provident fund, and its attitude is very clear, that is "reform", not "cancellation", and I fully agree with it. Since the central government’s attitude is still clear, if we want to reform, we should first make clear what the problems are in the provident fund, and then discuss what the solution is, not whether to cancel it, but whether to reform it. There may be many problems with the provident fund, for example, whether older employees who have no need to buy houses have the right to quit, whether individual employees have the right to choose the proportion of contributions within the upper limit, and so on.
  
  However, there have been two biggest problems with the housing provident fund: First, the investment method is single and the rate of return is too low. For example, the value-added rate of return in 2018 is only 1.56%; The direct result of the low value-added rate of return is that the deposit interest paid by employees is too low, and the interest is only calculated at 1.5%. If calculated according to the market-oriented investment rate of return, the loss is huge. Take the balance of 802.3 billion yuan in 2018 as an example. If it is entrusted to the National Social Security Fund Council for investment and the rate of return is assumed to be 6%, the interest income this year will be as high as 28 billion. Therefore, after more than 20 years, the interest loss will be several hundred billion yuan. For individual employees, the interest rate of 1.5% is far from outperforming the inflation rate, and the risk of depreciation is very obvious. The funds deposited in the account are shrinking every year; The interest rate of 1.5% is at least 10 percentage points lower than the social average wage growth rate, resulting in "welfare loss" doubling every few years. In the past 22 years, the unit proportional payment is almost equivalent to "nothing". In the past 22 years, the wage growth rate and population growth rate have exceeded 14%, which is called "biological rate of return" and "internal rate of return" (we can roughly understand it as actual purchasing power). Minus the interest-bearing level of 1.5%, the annual "welfare loss" will be at least 12%. After 22 years, the welfare loss of employees will be astronomical.From the perspective of the whole society, this is a huge loss of social welfare and a "transfer" of social wealth. The second problem is that the surplus funds can’t be used in the whole country between the areas with low overall planning level and high loan ratio (for example, 99.5% in Tianjin) and the areas with low loan ratio (for example, 78% in Qinghai). From the perspective of the whole society, the low level of fund management and regional separatism reduce the efficiency of "mutual assistance" of surplus funds.
  
  In view of the above analysis, there are problems in the provident fund system, but we should not give up eating because of choking. We should solve the problems in the provident fund as soon as possible, and we should not turn a blind eye to them. Otherwise, we will be irresponsible to the paid employees. From a certain point of view, we will "fatten" the state-owned banks with low-priced and high-quality assets. Since some scholars have put forward a motion to cancel the provident fund, policy makers should act as soon as possible with a sense of urgency and a high sense of responsibility for the people’s interests, so as not to let a good livelihood system become a "soft rib" for a long time. In order to get rid of the above two main disadvantages, the author puts forward four reform ideas or four reform options.
  
  First, expand the function and optimize the structure without changing the nature of the current administrative institution of the housing provident fund center.This is an improved scheme, the easiest and most convenient scheme, and the existing system and mechanism will not be changed. The areas of "improvement" include: in the investment system, we can adopt the mode that the basic old-age insurance fund for urban workers entrusts the National Social Security Fund Council to invest, and the provinces sign contracts with the National Social Security Fund Council respectively and agree on specific matters such as investment return rate, and all the real investment income is distributed to the paid employees as interest. In terms of business scope, provident fund centers in first-and second-tier cities are allowed to use value-added income and other funds to directly invest in and hold rental housing, and support paid employees to solve housing problems through leasing; Expand the coverage of deposits to cover urban migrant workers and even freelancers; At the level of overall planning, it will be promoted to national overall planning, and the mutual integration of funds between cities will be strengthened. Deposited employees can continue to deposit in different places, extract and use in different places, and lend; Establish a new loan allocation mechanism in the use of extraction, tilt towards low-and middle-income groups, and increase support for rental housing; Improve the efficiency in the operation mechanism and simplify the procedures for extraction and use; Strengthen the publicity according to law in supervision and regularly disclose information.
  
  Second, the national housing provident fund management company, a policy-based non-bank financial institution with independent legal person, was reorganized and established (the idea of "Fannie Mae and Freddie Mac" in the United States).The national housing provident fund management company issues bonds and securities in the capital market with national credit, expands the fund pool, and provides liquidity support and policy guarantee for ordinary people to use the housing provident fund; In terms of the use of funds, the National Housing Provident Fund Management Company does not directly issue loans, but supports the basic housing needs of paid employees by providing low-interest and long-term credit guarantees for paid employees. After being guaranteed by the provident fund management company, paid employees can choose any provident fund center and commercial bank to obtain loans. This method can promote the competition between provident fund centers and commercial banks, and improve the efficiency and service level of housing loans for paid employees. At the same time, the national housing provident fund management company provides funds for the provident fund centers and commercial banks by purchasing their mortgage assets in bulk. In the first-and second-tier cities with high housing prices, we will support the construction and operation of rental housing through loans or direct investment, and promote "both rent and purchase". Establish a national overall planning mechanism and a national housing provident fund fund fund management platform to realize national deposit and withdrawal and interbank lending; In terms of operation mechanism and supervision mechanism, it operates in the way of corporate governance structure of financial institutions and accepts supervision.
  
  Thirdly, the policy-oriented National Housing Bank was reorganized and established (the idea of China Postal Savings Bank).Based on the model of housing savings banks in developed countries, the national provident fund center will be reorganized into a unified national independent legal person financial institution, and the provincial and municipal provident fund centers will be reorganized into branches of the National Housing Bank, and bonds and securities will be issued in the capital market with national credit; Carry out policy-based housing savings business, establish a differential credit mechanism, and provide more favorable housing financial support to low-and middle-income groups, which can be deposited and connected in different places, and used and loaned in different places; Issue project loans to rental housing construction. In the operation mechanism, it operates according to the corporate governance structure of modern financial institutions, and establishes an incentive mechanism to promote efficiency and risk control; According to the regulatory mechanism of policy finance, the Ministry of Housing and Urban-Rural Development is responsible for the formulation and supervision of housing policy rules, while the central bank and the China Banking Regulatory Commission are responsible for the formulation and supervision of banking regulatory rules.
  
  Fourth, merge with enterprise annuity and integrate it into a comprehensive provident fund system (the idea of Singapore Central Provident Fund).Considering the aging trend, following the principle of life cycle, taking into account the capital needs of urban residents in housing and pension, a unified personal provident fund account will be established throughout the country. According to the housing and pension, two sub-accounts are set up. The housing account implements "low deposit and low loan", and the funds in the housing account can be extracted for renting or buying housing. When employees have no provident fund loans or housing consumption needs, the funds in the housing account are transferred to the pension account. Set up a policy-based non-bank financial institution to be responsible for the investment and operation of the comprehensive provident fund pool, and play the dual role of the current housing provident fund and enterprise annuity.

The M8 has no camouflage real car exposure, and the M9 has the same front face and the door handle has bright spots.

Here, the M9 has just issued the happy news that it has exceeded 200,000 units in the past 12 months, and there, the M8 can’t wait to show its true meaning. Judging from the spy photos exposed, this M8 test car has no disguise, and the whole front face shape is fully displayed, which generally follows the design of the M9 of the big brother, reflecting the family inheritance. Next, let’s take a look at it with the car brother.

After the spy photos are exposed, we can clearly observe the design details of the boundary M8. The front face is very similar to that of the boundary M9. The flat arc lamp groups on both sides are connected above the nose by a penetrating lamp strip, and the whole headlight group is located below the lamp strip, or equipped with a smart lamp curtain of the same paragraph as the boundary M9. The outer side of the lamp group is connected with the longitudinal air intake, the center of the front of the car is a large-area closed panel, and the trapezoidal lower grille is decorated with chrome trim strips to enhance the sense of luxury and exquisiteness.

The lidar on the roof is a remarkable feature of the car, and other details come down in one continuous line with the car M9, including round and full body lines, flat side windows, chrome-plated decoration, large-size dense silver wheels, etc., which has a visual sense of the car M9 with a small size. The only difference is the door handle, which is not fully hidden, but a semi-hidden design similar to Xiaomi SU7, and its practicability has been improved to some extent.

There is not much suspense in the shape of the rear end, and the through taillight group presents a structure with thin middle and thick sides, which is consistent with the family design. There is a slightly inclined rear windshield and a large spoiler above, and a plurality of horizontal lines are added to the rear enclosure to enhance the visual width and layering.

The interior part can refer to the spy photos exposed before, and is equipped with an integrated triple screen that runs through the center console. HUD heads-up display and star ring scatterers will not be absent. There are no physical buttons in the central channel, and there is a wireless charging panel with dual mobile phones at the front, or equipped with electronic arms.

The power part is speculated to be similar to the M9, which provides extended range and pure electric power. Referring to the M9 model, the extended range version is equipped with a 1. 5T range extender and front and rear dual motors, with a comprehensive power of 365kW;. The pure electric version is equipped with a standard dual-motor four-wheel drive system with a comprehensive power of 390kW.

The positioning of M8 is between M9 and M7, so it is estimated that its price range is 350,000-450,000 yuan, which provides a new choice for consumers who want to buy M9 but have insufficient budget. In terms of competing products, Ideal L8 and L9 are undoubtedly the most direct competitors. In addition, Tengshi N9 and Linke L946, which will be listed soon, will also become potential competing products. Whether the new car can continue the dominance of the world M9 remains to be seen.

The Island responded to plagiarism and said: It is an independent original work.

  Recently, the screenwriter Yu Mengyuan sued the movie The Island for script plagiarism. In this regard, The Island filmmakers and director Bo Huang himself have not made a public response. Last night, The Island’s film company commissioned a lawyer to issue an official statement in Weibo, denying the theory of "plagiarism", saying that The Island was an independent original work and demanding that Yu Mengyuan immediately delete the relevant articles.

  Previously, the screenwriter Yu Mengyuan @ 个个个个个个个 Bess wrote a post in Weibo, claiming that The Island of Bo Huang copied and borrowed from her 2013 play "Men’s Crisis", and both of them have similarities in story theme and characters. She revealed that she had invited Bo Huang to play first hero’s "Qian Jin" in the name of a film and television company, but Bo Huang refused on the grounds that the story frame and character types were not suitable. In the following years, she tried to contact and lobby Bo Huang to play the role of "Qian Jin" through various relationships and channels, and even contacted Bo Huang’s good friend Wang Xun, and lobbied by inviting Wang Xun to play the role of a tour guide. But unexpectedly, Bo Huang wrote, directed and acted his first film, The Island, with the same story frame and character types.

  In The Island’s lawyer’s statement, two points are clearly mentioned: The Island is an original work independently created by the screenwriter and the film creative team, and it belongs to the previous creation; Weibo’s article claims that "copying the story creativity and framework in the script of Men’s Crisis and rewriting a lot of details in order to avoid the risk of infringement" does not exist at all, which is a distortion of the facts.

  In response to Yu Mengyuan’s accusation, a few days ago, directors Han Yan and Zhang Xiaobei publicly voiced in Weibo, proving that they had heard Bo Huang tell The Island’s story as early as 2010 and 2011, and opposed the theory of "plagiarism". Han Yan said: "One night in the cafe downstairs of Bo Huang’s teacher’s house, he told me a story about a desert island, and the story context and plot were almost the same as those presented by The Island. It was the winter of 2010, and I was preparing for "The First Time", which was deeply imprinted with time. I am not familiar with Bo Ge, and I don’t even have WeChat. Seeing the premiere is also invited by my colleagues in Light. I don’t believe in this plagiarism identification, just because I am a creator’s respect for another creator. "

  Zhang Xiaobei also explained: "In August or September of 2011, I had a script planning meeting with Mr. Bo Huang on this project. At that time, Director Guan Hu was also present, and he introduced me to the planning meeting. At the meeting, Mr. Bo Huang explained the whole early script completely, including the creative source, story structure, characters, main conflicts and ending, which is basically the complete embryonic form of the current film. I don’t have a personal relationship with Teacher Bo Huang, but I stand up because I respect a serious creator. "

  The explanations given by the two directors are basically the same as those given by Xú Zhēng and Liang Jing at the film premiere. At that time, Xu Zheng once said: "The first time I heard Bo Huang say that he wanted to make an allegorical movie was in Blue Harbor, almost in 2009 and 2010." Liang Jing also said: "In 2010, I knew that Bo Huang wanted to direct this play. At that time, he said that he would not let Guan Hu direct it. He went to perform with Xú Zhēng and Baoqiang."

  Before the "plagiarism theory" was put forward, our reporter interviewed Bo Huang just before the release of The Island. At that time, he also made it clear that The Island’s story originated in 2010. He was first asked by a friend’s company to plan a promotional film for an amphibious bus, and he thought wildly: If a group of people were trapped on an island, many interesting things might happen. Later, after watching Farewell Atlantis, Bo Huang was obsessed with the ending of the film. "All the survivors hid in the ark, but I think the story behind is more interesting. Can they really find the landing site? Will there be love or struggle in the ark? " Later, the script was constantly revised, until after the release of "Seeking the Dragon", Bo Huang stopped taking the play and devoted himself to The Island’s script creation. Our reporter Li Li

The General Administration of Market Supervision issued quality and safety risk warnings for four types of products, including gas cookers.

  Cctv newsIn order to remind users to correctly purchase and use gas appliances, prevent and resolve gas safety risks, and effectively protect people’s lives and property safety, the General Administration of Market Supervision issued four types of gas appliances product quality and safety risk tips, including gas cookers, connecting hoses for gas, pressure regulators for bottled liquefied petroleum gas, and combustible gas detectors.

  The market supervision department will focus on industrial products with large safety risks, strengthen quality and safety supervision, keep the bottom line of product quality and safety, and ensure high-quality development with high-level safety.

Risk warning of gas cooker

Gas cookers are gas burning appliances that directly heat cooking utensils with fire, among which domestic gas cookers are compulsory certified products (CCC certified products). Through product quality supervision and spot check, it is found that some domestic gas cookers have potential risks in terms of heat load, carbon monoxide concentration in dry flue gas (indoor type) and gas conduit.

Users are reminded to pay attention to the following points when purchasing and using:

1. Pay attention to the product nameplate when purchasing, and confirm whether the product name and model, the type of gas used, the rated gas supply pressure, the rated heat load and other information are complete. Pay attention to check whether there is CCC certification mark for domestic gas stoves.

2. The product structure of gas cookers with different gas sources is different, and the appropriate products should be selected according to the types of gas sources.

3. Pay attention to check whether there is a flameout protection device.

4. Gas cookers should be installed by professionals in strict accordance with the requirements of the manual and relevant regulations.

5. Regularly clean the places that are easy to be blocked, such as the fire cover and nozzle, so as to keep the gas cooker in the best combustion condition. When cleaning, try not to disassemble the burner components as much as possible, and be careful not to damage the gas pipeline, so as not to cause gas leakage accidents.

6. The national mandatory standards stipulate that the life of household gas cookers should be 8 years from the date of sale, and the gas cookers that exceed the service life should be replaced in time.

7. Encourage users to install and use gas smart meters, gas leakage safety protection devices, self-closing valves, independent smoke fire detectors, combustible gas detection alarms and other protection devices to actively prevent gas leakage risks.

8 resolutely resist and refuse to buy "three noes" products without factory name and address, quality certificate and production date.

Risk warning of connecting hose for gas

The connecting hose for gas is an important part of the connecting pipeline of gas appliances or the pressure regulator of bottled liquefied petroleum gas. The commonly used ones are stainless steel corrugated hose, rubber and plastic hose, metal-coated hose, etc. Through product quality supervision and spot check, it is found that some connecting hoses for gas have potential risks in terms of flexibility, hose length, tensile strength and hose joint thread.

Users are reminded to pay attention to the following points when purchasing and using:

1. Stainless steel corrugated hose and metal-coated hose have good bending performance, strength, corrosion resistance and high temperature resistance, which can effectively prevent external damage or insect bites.

2. Users should purchase products with product name, specification, manufacturer’s name, product standard number and other information; For rubber and plastic hoses, the above information, production date and service life should be marked every 300mm or on a single hose.

3. When using stainless steel corrugated hose, we should pay attention to whether the use and connection form of hose are consistent with gas appliances; When using rubber and plastic hoses, clamps should be used to fix them at the joints at both ends.

4. Rubber and plastic hoses should be installed below the height of the stove surface, away from the flame, so as to avoid flame baking accelerating the aging of hoses; The service length shall not exceed 2m, and it shall not cross walls, ceilings, floors, doors and windows, and it shall not be used under bending, stretching, torsion and compression.

5. Gas connecting hoses should be inspected and replaced regularly, especially rubber and plastic hoses that are found to be hardened, aged, cracked and loose or exceed the service life (the service life stipulated by national mandatory standards is not more than 3 years), and should be replaced in time.

6 resolutely resist and refuse to buy "three noes" products without factory name and address, quality certificate and production date.

Risk warning of pressure regulator for bottled liquefied petroleum gas

The pressure regulator for bottled liquefied petroleum gas (hereinafter referred to as the pressure regulator) is an accessory for burning appliances after reducing the high pressure of liquefied petroleum gas in gas cylinders to a fixed low pressure. Through product quality supervision and spot check, it is found that some voltage regulators have potential risks in product structure (with adjustable function) and outlet pressure.

Users are reminded to pay attention to the following points when purchasing and using:

1. According to the national mandatory standards, the rated outlet pressures of household regulators and commercial regulators are 2.8kPa and 2.8kPa/5.0kPa respectively, and the outlet pressure of each regulator is fixed and cannot be adjusted during use. If the outlet pressure is too high, it may lead to gas leakage at the pipeline joint or directly fall off, or it may produce toxic and harmful gases due to insufficient combustion, which has obvious safety risks.

2. The outlet pressure of the commonly known medium-pressure valve is generally higher than 50kPa or even several hundred kPa, and it has a regulating function, which has a huge safety hazard. It is not allowed to use the medium-pressure valve instead of the voltage regulator.

3. The voltage regulator is a special industrial product, so it is not suitable to buy it at will. It is recommended to buy it in a professional unit that operates such products and listen to the advice of professionals. When the outlet of household voltage regulator is a hose connector, products with over-current cut-off safety devices should be selected.

4. Give priority to the voltage regulator products with the manufacturer’s name, trademark, model, production date, service life and gas flow direction marked on the shell. When purchasing, check that the product packaging should be accompanied by instructions, inspection certificates and other materials.

5. Incorrect installation may easily lead to abnormal operation of the voltage regulator, so it should be installed, replaced and maintained by professionals in strict accordance with relevant regulations and specifications.

6. Conduct regular safety inspection. Use high-concentration detergent water and soapy water to smear on the joints and interfaces of the voltage regulator shell first, and then open the valve of the liquefied petroleum gas cylinder. If there is foam, it means air leakage, and it should be replaced in time.

7 resolutely resist and refuse to buy "three noes" products without factory name and address, quality certificate and production date.

Risk warning of combustible gas detector

Combustible gas detector is a device with alarm function of gas leakage and incomplete combustion. Through product quality supervision and spot check, it is found that some household combustible gas detectors have potential risks in alarm action value, alarm repeatability, orientation and low concentration operation.

Users are reminded to pay attention to the following points when purchasing and using:

1. Combustible gas detectors are generally divided into natural gas type, liquefied petroleum gas type, artificial gas type, etc., and corresponding alarms should be selected according to the types of gas used. When purchasing, pay attention to the information such as the type of detection gas, power supply mode and production date on the nameplate.

2. When installing, it should be installed in a suitable position according to the requirements of the manual to avoid being installed in a sheltered place or a place that is easy to be polluted. Before use, start the self-check function of the alarm to confirm that the product has entered the normal monitoring state, and observe whether the indicator light is in the normal working state.

3. During use, keep the power on for a long time to avoid frequent power off and power on. Pay attention to the regular cleaning and maintenance of the product to avoid the blockage of the air inlet. After restarting, it is necessary to start the self-inspection function again to ensure the normal functions.

4. If an alarm is given, turn off the gas valve first, open the doors and windows for ventilation, and do not turn on the light or turn on any electrical switch. Find out the cause of gas leakage. If the cause cannot be confirmed, contact the gas company immediately for treatment.

5. If the service life is indicated in the product manual, the products that exceed the service life should be replaced in time.

6 resolutely resist and refuse to buy "three noes" products without factory name and address, quality certificate and production date.

In the world’s first trailer for "Black Adam", the action scenes are fierce and hot, giving the audience a glimpse of Black Adam’s strength and ruthlessness. Dwayne Douglas Johnson, the "boulder", plays Black Adam with the power of six gods similar to that of Shazam, but different from Shazan’s escape temperament, he has suffered painful spur, which has created a character that is both good and evil now. Destroying or saving the world is only a matter of one thought. The Black Adam in the preview is fierce, powerful and dangerous, which makes people more curious about the plot. In addition, members of the Justice Association, such as Dr. Destiny, played by former James Bond pierce brosnan, who are familiar to China audiences, also appeared in the first trailer, which made people shine.

The film "New Youth" turned into the leader of the whole team.


1905 movie network news In a blink of an eye, from spring to summer, the race has been more than half. The sixth program broadcast on May 17 finally showed a dramatic turning point: the new wave class, which lost five times in a row, now won quite a beautiful Jedi counterattack; Montage class just changed its monitor and entered the elimination dinner. Chen Hongzhi, the old monitor, "took the blame" for elimination, and Pu Yixing, the "new official", mastered the power of life and death when he took office. All kinds of mistakes, rebirth, choices and contradictions are swarming, and this game is getting bigger and bigger.

Who says the school flower is just a vase? Wang Jingwen became the first key figure in the new wave.

 

The star tutor of this issue is Zray, the "Liu Xing" in Family with Children. When he grew up, he came to New Youth in Film. He never thought that he would become a "lucky star" for eight young people. Why do you say that? In the first five programs, the New Wave class was defeated repeatedly, and after five elimination dinners, there were only eight people left in the whole team. When Zray came, the plot of the whole program began a huge reversal, and the New Wave class finally won! This statement is actually just a joke. After watching this program carefully, you will find that the Jedi counterattack of the New Wave class is really wonderful.

 

First of all, after the fierce conflict between Zhao Ye and Cao Lei at the last elimination dinner, the members of the New Wave class seemed to instantly understand the meaning of teamwork. In the first round of "Braving the Single-plank Bridge", Zhao Ye and Cao Lei fought side by side, and Cao Lei was injured three times, but his mentality remained optimistic, which also changed Zhao Ye’s view of "only shouting and making little contribution". Secondly, after losing so many games in a row, every team member died. The most classic is what Merxat Ayi said: "Just try props and have fun." The heart is put down, but the world is broadened.

 

Here, I want to give 32 praises to Wang Jingwen, the school flower of Shangxi. In this issue, Wang Jingwen showed a rare leadership temperament among female students: First, in the first round of competition, Chen Jianhan fell, but the squad leader Zhao Ye still advocated "rushing", and Wang Jingwen resolutely opposed it, thinking that teammate safety is the bottom line, and the winning and losing heart must stand aside; Secondly, the "human bone puzzle" link, when Wang Jingwen directed his blindfolded teammates to take the puzzle, his speech was neat and orderly, which was also the key to the final victory of the new wave class. Even Zhao Ye had to admit defeat, and his voice was hoarse when he was emotional, which was not conducive to the cooperation between teammates.

 

Think back to what Laure Shang, the last tutor, said: Why are there so many masters left in the New Wave class, but they still fail again and again? It is precisely because the powerful are not United, falling apart and scheming that there is absolutely no hope of victory. In this issue, President Liu Yiwei fulfilled his promise of "changing hair style as long as the new wave class wins" and wore an exaggerated wig. This scene is so inspiring and touching. Although the victory is only temporary, life needs such feedback, so that we can feel the meaning of struggle.

 

Chen Hongzhi’s "stepping down" still makes the loser bear the consequences of failure for the behind-the-scenes strategist

 

Although the montage class suffered from waterloo in this issue, as the soul of this group, Chen Hongzhi’s performance was outstanding: at the beginning of the program, Chen Hongzhi resigned as the monitor on the grounds of "giving the leadership to everyone to experience", and Pu Yixing, who has always been cold, went into battle. Some people say that this decision was the direct cause of the first defeat of the montage class, and even Chen Hongzhi himself felt guilty for it, and asked everyone to "throw himself out" when he eliminated the dinner party. But in fact, this is not the case. The most important issue in the failure of Montage Class is teamwork, and the responsibility for failure must not be put on a leader.

 

For example, in "Braving the Single-plank Bridge", Lu Song had problems in cooperation with his teammates, and even his emotions were out of control, which had a great impact on the psychological state of the whole team members. In addition, although the montage class is numerous and powerful, it is by no means an elite, and it happens that the new wave class also left Chen Jianhan, the academic bully who answered the questions with "one hundred shots and one hundred hits", and there is nothing to be unconvinced by losing to them; There is also the link of "human bone puzzle", in which Chen Mengqin sent by montage class is in a state of confusion due to poor command, and his partner Ma Xiao has a little emotion again. Compared with the strong combination like Wang Jingwen and Zhao Ye, the strength gap is obvious.

 

The team problem of montage class is more obvious at the elimination dinner. After the first round of voting, Zhang Yixiao and Chen Mengqin were decided by girls, while Lu Song and Xiao Junlun were decided by boys. When Xiao Junlun was eliminated, some girls had the same votes, and the new monitor Pu Yixing hesitated. Xiao Junlun actually asked to keep Chen Mengqin on the spot because they were partners. At this time, Lu Song refused to accept it again, and also told Pu Yixing that Zhang Yixiao attached great importance to this platform.

 

Therefore, Chen Hongzhi showed great talent in this link, because Pu Yixing took his advice and decided to eliminate Chen Mengqin, who failed in performance. "Since you choose to play, you will have more opportunities for shots and performance. If you fail, you will have to bear the price." Although Chen Hongzhi’s "taking the blame and seeking elimination" is a bit fishy, even if it is fishy, it is the work of a generation of bullies. In the final decision-making, Chen Hongzhi is even more calm and wise: the deep affection between the players is understandable, but the survival of the fittest should be ensured when eliminated, thus ensuring the quality of the team. The strong rely on strength, and the weak will only fight for feelings.
