Warning everywhere

Natural baths are still raging.

The tragic incident sounded the alarm for the reservoir players. However, after the drowning accident, there are still hundreds of people "hiking" every day in Qinglong Mountain Reservoir.

"The accident happened on July 12, and there were fewer people swimming on the 13th, but the next two days happened to be weekends, and there were more people playing with water. On the afternoon of the 16th, there were fewer talents because of the heavy rain." The relevant staff of Fusheng Police Station of Yuecheng District Public Security Bureau told the reporter that after the accident, they strengthened the inspection and pulled up a huge red warning banner on the dam of the reservoir.

On the afternoon of July 14th, the reporter came to the reservoir specially, heard the incessant horn call of "No Entry into the Water", and saw various fixed warning signs, which read, "There have been many drowning accidents in this reservoir over the years! The water depth of the reservoir, please pay attention to safety! " "The water depth is dangerous, pay attention to safety" and so on.

The reporter saw that Shaoxing Yuchacun Tea Industry Co., Ltd. specially set up a warm reminder iron sign beside the reservoir, which said that the water in Qinglongshan Reservoir is deep, the water temperature is low and there is obvious stratification. Please pay attention to safety, do a good job of personal protection, and take responsibility for accidents. The reservoir is the core scenic spot of Matcha Town. Please take all the garbage away or put it in the dustbin.

"The Qinglong Mountain Reservoir in Fusheng Town, Yuecheng District, with tea gardens, reservoirs and green hills set each other off, is a well-known punching point in online celebrity. Every summer, the temperature here is several degrees Celsius lower than that in the urban area, which is a good place to cool off in summer. " Mr. Jin, who came here to swim, told reporters that he is an outdoor sports enthusiast and has been swimming in Qinglong Mountain for 10 years. In recent years, there are more and more people playing with water in the reservoir, especially in the evening on hot days in summer. Traffic police have to be dispatched to maintain order, otherwise, the vehicles driving to swim in Qinglong Mountain will be easily blocked. After the accident, the "natural bathing place" is still "noisy".

Difficulties in road closure

The relevant departments are helpless.

The reporter learned that there are two routes to the reservoir. One is to go directly to the reservoir from Yucha Village Tea Demonstration Park. This road is not accessible by the staff of the demonstration park. The other road is from the Zanggong line in Huangjiaao Natural Village, Paikou Village, Gaobu Street.

The staff of Shaoxing Yuchacun Tea Industry Co., Ltd. told the reporter that although tea gardens are often irrigated with water from Qinglongshan Reservoir with the consent of relevant departments, Qinglongshan Reservoir does not belong to Yuchacun. From the perspective of tea garden management, the meeting of people flow brings many problems, but the company is not the owner of the reservoir and cannot stop tourists from visiting the reservoir.

"It is suggested that we close the road to ensure safety." The relevant staff of Fusheng Town Government said that the road to Qinglongshan Reservoir belongs to Gaobu Street, and they have no right to close the road. The staff of Gaobu Street also recognized this statement. Why don’t Gaobu Street block the road leading to Qinglong Mountain? The relevant staff explained that the villagers often have to take care of the mountain behind the reservoir, and the road closure will definitely be complained by them.

Outdoor swimming

Two conditions are indispensable.

Xiaojin, a winter swimmer, is a frequent visitor to Qinglong Mountain Reservoir. He is worried about the swimmers who come here.

Xiaojin told reporters that even if it snows, there are tourists visiting Qinglong Mountain. Outdoor swimmers generally receive strict safety education, knowing that reservoir swimming is also a dangerous place for experienced swimmers at any time, so they will take safety measures in advance. "There are two conditions for outdoor swimming, both of which are indispensable. First, the buoyancy ball must be tied, and the tightness and tension should be checked before launching to ensure safety; Second, many companions must go together, so that they can pay attention to each other’s safety in the reservoir. Once an accident occurs, it is relatively easy to rescue. "If we forget to bring the buoyancy ball, we would rather run empty than go into the water."

"It is a great safety hazard to swim outdoors without a buoyancy ball." Outdoor swimmer "Shui Ge" said that it is difficult to accurately find the drowning person in a wide water area for timely rescue without a buoyancy ball. At the same time, because the water area is wide and unfathomable, it is more difficult to rescue than the swimming pool.

The reporter saw from the photos and videos sent by Xiaojin and others that after the drowning accident in Qinglongshan Reservoir, the enthusiasm of wild swimmers has not diminished, and "outdoor swimming white" is still the mainstream. There are so many people in swimsuits in the huge reservoir, but there are few bright buoyancy balls and life jackets.

Reservoir drowning

It hurts to be helpless.

"There were several people who came to the reservoir to swim with the drowning young man that day. They soon found that they could not find him and called the police. The police are also very fast, but it is really not easy to find someone in such a large reservoir. " Aunt Li from Zangong Village, Fusheng Town goes for a walk in Qinglongshan Reservoir every evening. She and some villagers witnessed the rescue situation at that time.

"When it was salvaged, everyone was sorry to see that the deceased was so young." A staff member who participated in the rescue at the scene said that even if someone saw drowning, it was very difficult to rescue. Last year, in Longchuan ‘ao Reservoir, Wufengling, not far from here, a young man fell into the water playing with paddles, and his companions and villagers at the reservoir could only watch him slide farther and farther with heartache, but they were helpless.

The reporter also learned that in another reservoir last year, a local villager who often swam in the reservoir slipped farther and farther in the reservoir because he didn’t wear a buoyancy ball, which led to the tragedy of drowning. "The reason is unknown, it may be dizziness, or it may be caused by cramping in the water or sudden cardiovascular disease." Witnesses said.

"When there is drowning in the reservoir, it is difficult to rescue even trained professionals. In short, the reservoir is not a place to swim. " Hu Jianqiang, a member of Shaoxing Jiulong Rescue Team, told reporters that he has participated in about 100 summer reservoir swimming and drowning accidents since he was engaged in rescue work for six years, and it is very difficult to salvage drowning people in the reservoir, let alone rescue drowning people. Hu Jianqiang said that at present, the reservoirs in Yuecheng District are just public existence like roads and mountains. No reservoirs charge swimming fees because of their nature, and there are no professional rescuers to ensure their safety. Therefore, no one should take risks.

Playwright

Strengthen self-safety awareness

Qinglong Mountain Reservoir has a total storage capacity of more than 300,000 cubic meters. It is a small reservoir mainly for irrigation and combined with flood control. The height of the reservoir is more than 10 meters and the deepest part is about 7 meters. In recent years, the number of people who come here to enjoy the cool water every summer is bursting, and the local departments post warning signs around the reservoir to remind them of safety through loudspeakers, and also arrange personnel to patrol and persuade them at high frequency.

"Some tourists who go their own way will even swim to the deepest part of the reservoir center. We are constantly adding warning signs and rescue facilities around the reservoir, and we plan to add some long bamboo poles for emergency. " The staff of Fusheng Police Station of Yuecheng Public Security Bureau said that many tourists not only turned a deaf ear to their kind reminders, but sometimes laughed at them.

"As a non-drinking water reservoir, we have no right to force people to pick up from the water or prevent them from entering the water. The safety responsibility will ultimately be borne by tourists themselves." A staff member familiar with Qinglong Mountain Reservoir said that as early as 2018, a woman drowned here. A month or two earlier this year, a fisherman accidentally fell into the reservoir and drowned. On July 12, another tragedy occurred. It can be seen that swimming in the reservoir is dangerous, so players must strengthen their awareness of self-safety to prevent tragedies.

Jin Jianhao, a lawyer of Zhejiang Jindao (Shaoxing) Law Firm, said that according to the relevant provisions of the Civil Code, the main functions of reservoirs are freshwater aquaculture, irrigation, power generation and non-drinking water supply, and the main obligation of reservoir managers is to ensure sound water conservancy facilities and sound functions. Therefore, the reservoir managers need not bear the responsibility for the drowning accident, and the responsibility for the accident should be borne by the parties or their guardians.

Be yourself safe.

First responsible person

On July 12th, a young man drowned in Qinglongshan Reservoir in Yuecheng District. In midsummer, the drowning accidents of reservoir "wild swimming" are common, which makes people sigh. Tragedy repeats itself, alarm bells often ring, but there are still "brave people" who advance wave after wave. The author believes that it is necessary to weave three "protective nets", especially to keep the "protective net" of personal safety responsibility, so as to avoid tragedies from the source.

Keep the "protective net" of personal safety responsibility. Everyone is the first responsible person for his own safety, and he should think about the importance of safety and keep the responsibility of safety in every word and deed. In terms of legal liability, Article 18 of the Civil Code clearly states that adults with full capacity for civil conduct can independently carry out civil legal acts. To put it bluntly, adults can fully recognize the legal consequences of their actions, independently carry out civil legal acts of their own will, acquire civil rights and assume civil obligations for themselves, and bear full legal consequences for their actions. Adults should be aware of the risk of "wild swimming" in the reservoir. Without other infringement, once a drowning accident occurs, as the victim of the accident, there is no doubt that they are the first responsible person.

In the tragedy of drowning, if a minor, according to the law, parents have the right and obligation to educate and protect their minor children. If a minor child causes damage to others, the parents as guardians shall bear civil liability according to law. Therefore, parents are the first responsible persons for the safety of minor children.

In terms of safety responsibility, no one can be lucky. Some talented people are bold, and "wild swimming" doesn’t take any protective measures. As a result, the follower jumps into the water without taking any protective measures, gets dizzy after drinking, and plunges into the water after being tired … However, it is often in a moment of negligence that tragedy happens under the nose.

Before taking part in "wild swimming" and other similar activities, you should be predictable about the risks. The "wild swimmers" who have just experienced high temperature fatigue are prone to cramps and other phenomena. Build a strong ideological defense line, always tighten the security string, protect your personal safety, and avoid causing damage to others. Only when you are the first person responsible for your own safety can you reduce the tragedy of drowning from the source.

Improve the "protective net" of reservoir safety management. Rural reservoirs are used for flood discharge and irrigation, and do not have swimming function. However, in reality, some reservoirs are loosely managed, and people can freely enter and leave, leaving an opportunity for "wild swimming". Of course, according to the provisions of the Civil Code, as a reservoir manager, if he fails to fulfill his security obligations and causes damage to others, he shall bear tort liability. This also tells us that in the event of a "wild swimming" drowning accident, the reservoir manager may not be completely irresponsible. If he fails to fulfill his security obligations and cannot prove that he is not at fault, he needs to bear tort liability for the accident. Of course, if the reservoir management party fulfills the duty of warning and reminding others that it is forbidden to enter the reservoir without authorization, it does not need to bear tort liability.

Therefore, the management unit should build a safety net and strengthen on-site supervision and management, such as closing the reservoir waters. If it can’t be closed, we can recruit volunteers, increase the number of inspectors, increase the frequency of inspections, strengthen law enforcement, and take measures such as criticism, education and fines to keep "wild swimming" out of the library. For those who refuse to obey dissuasion and insist on wild swimming, the management can report to the public security organ for punishment.

Construct a "protective net" for outdoor safe swimming. Knowing that there are tigers in the mountains, I prefer to go to the mountains. Why do "wild swimmers" flock? The answer is simple: the natural environment of open waters is good, the water quality is good, and swimming is more delicious. In Shaoxing, a water town with dense river network, special outdoor rivers and special hydrophilic areas can be set up to meet the hydrophilic needs of the public. In fact, in the early years, a hydrophilic river was set up in the celebrity square, which was managed by special personnel on site. There were many swimmers in midsummer every year, and no drowning accident occurred. More such safe outdoor swimming places, combined with "sparse" and "guided", will naturally reduce the number of "hikers" in the reservoir.

Wild swimming is risky, so you need to be careful when you get into the water. There is only one life, and life is never repeated. Please cherish your life, be responsible for your own and others’ lives, and don’t let the tragedy happen.　

Be sure to get the aero engine up!

Wen | Xiong Wenming

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.

CCTV News:In order to further promote the development of the language service industry, expand the export scale of language services and enhance the national language service capacity, the Ministry of Commerce, the Ministry of Education and other departments have built a number of language service export bases this year, which have made continuous progress in technology while cultivating language translators.

Liu Junrong is an English translator, majoring in language from undergraduate to graduate. Her first part-time job was not as an English tutor, but as a part-time translator on a language website.

Liu Junrong, an English interpreter in the translation center of a language information technology company in Sichuan;The business volume is very large, and there are many fields and languages. Because I am engaged in English, I chose the social science field that I am interested in, so that I can earn some pocket money and improve my study skills.

JUNG WOO, Product Manager of R&D Center of a Language Information Technology Company in Sichuan:This is the data of our backstage delivery. It can be seen that the delivery volume in the past 30 days is around 7,866 orders, and the delivery time is mainly concentrated from Monday to Friday, and the highest single day may reach more than 300 orders.

This company was recognized as an export base for language services by the Ministry of Commerce this year, with "language talent training and employment" as the core, and actively cooperated with many universities in Sichuan and Chongqing. The overseas income has increased significantly compared with 2020, with more than 3,000 foreign-related orders.

　　　　　　 Zhu Xianchao, Chairman of a Language Information Technology Company in Sichuan:In the future, we will actively expand overseas markets and plan to open branches or offices in Southeast Asia, Europe, Africa and other places to provide more convenient localization services for China enterprises to go overseas and overseas enterprises to invest in China.

Language translation needs not only the cultivation of talents, but also the improvement of technology. In a translation company in Hubei, an English manuscript of about 5,000 words only needs to be uploaded with one click, and each order has a customized translation payment scheme, and the order also relies on big data for intelligent distribution.

Xie Fei, a translator of a translation company in Hubei:Orders can be placed all over the world, because the whole process of this project is automated, so the time will be very short. They split a project into dozens or even hundreds of projects and recommend it to thousands of translators at the same time.

In recent years, with the continuous spread of overseas epidemic, the environment of international trade and cross-border communication has changed, which has a certain impact on the development of interpretation services such as overseas interpreters’ stationing and exhibition services. In the face of sudden challenges, this company chose to persist in continuous research and development in technology and strive to surpass the curve.

He Zhengyu, Dean of the Research Institute of a translation company in Hubei:We are not limited to machine translation, but also introduced AI technology and our own machine translation engine. The amount of data used by the overall vertical engine may have exceeded 1 billion. In this case, the number of projects that one person can trade at the same time will become a lot.

Russian customers of translation platform:The translation of a 200,000-word tender document takes one week in the traditional mode, and this platform can be shortened to less than 24 hours, which will gain more time for our enterprise.

　　Xinhua News Agency, Jinan, December 16th: Birds fall in love with the Yellow River Estuary — — Visit to the Yellow River Delta National Nature Reserve

　　Xinhua News Agency reporters Wang Nian and Wu Shuguang

　　Since the beginning of winter, the scenery of the Yellow River Delta Nature Reserve in Shandong Province is more like a beautiful picture of a scenery film — — Between the waves, the reeds on the shoals are like snow, and groups of migratory birds are strolling comfortably or spreading their wings, and the beautiful songs are one after another.

　　The Yellow River flows into the Bohai Sea from Dongying, Shandong Province, and its alluvial Yellow River Delta has a complete wetland ecosystem in warm temperate zone. In 1992, a national protected area with a total area of 153,000 hectares was established here, which played an important role in protecting the newly-born wetland ecosystem and rare and endangered birds. In 2013, the wetlands in the Yellow River Delta were listed in the list of internationally important wetlands by the International Convention on Wetlands; In 2018, Dongying ranked among the first batch of "international wetland cities" in the world.

　　When the reporter visited the nature reserve, he saw that the red-crowned crane walked gracefully, the white crane, the wart-nosed swan and the white spoonbill were hovering at low altitude, and the solitary oriental white stork stayed quietly in the nest most of the time … …

　　Liujing, head of the Ecological Monitoring Center of the Yellow River Delta, told the reporter that the number of birds in the nature reserve has increased from 187 when it was built to 371 now, including 25 species under national first-class protection and 65 species under second-class protection. The number of 38 species of birds exceeds 1% of the global total. Millions of birds migrate here every year, and some of them even spend the winter and breed here.

　　"This is an important transit point for bird migration, with ‘ Bird International Airport ’ The reputation of the migration peak is extremely busy. " Zhao Yajie, a researcher at the reserve, said that among the nine bird migration routes in the world, two routes, East Asia-Australasia and the Pacific Rim, pass through the Yellow River Delta.

　　Since last year, rare birds such as white pelican and spoonbill snipe have been discovered in the Yellow River Delta. However, in the view of researchers, the national first-class protection of birds, Oriental White Storks, is a testimony to the continuous improvement of the ecological environment. They only passed through the Yellow River Delta in their migration at the earliest, and began to nest here in 2003. In 2005, they first bred two nests of seven young birds in the wild. Observations show that this year, Oriental white storks have bred 324 chicks in 120 nests, with a total of 2278 chicks. "According to the information we have, it is undoubtedly the largest breeding ground for oriental storks in the world." Zhao Yajie said.

　　This is a bird flock taken near the dampproof dike in Kenli District, Dongying City. Ren Xiaojie

　　The reporter learned that the reserve not only insists on protection priority and natural restoration, but also takes the initiative and acts scientifically. For example, oriental storks like to nest and lay eggs in tall trees to hatch chicks, but there are no such trees in the Yellow River Delta. After careful research, the reserve has built 115 artificial nests for oriental storks, which proves to be effective. The reporter saw that the bird’s nest with a diameter of more than 2 meters on the high cement pole was quite eye-catching.

　　At the same time, since 2002, the local area has taken advantage of the favorable opportunity of the Yellow River to adjust water and sediment to replenish water, and successively implemented habitat protection projects for key species such as oriental white stork and black-billed gull, and the species and number of birds have increased significantly.

　　"Water is the life of the wetland. There are water, fish and birds." Tianpeng Wang, the stationmaster of the 1,200-meter management station in the nature reserve, said that continuous water supply for many years has effectively curbed the degradation of wetlands, restored the ecology, and steadily increased the biodiversity of wetlands, attracting more and more birds to inhabit and breed here. According to the introduction of Shandong Yellow River Bureau, Diaokou River was the flow path of the Yellow River before its diversion in 1976. Since 2010, the ecological water supply of this flow path has reached 381 million cubic meters.

　　Because of the strict requirements for breeding sites, the black-billed gull, a national first-class protected bird, is often regarded as an indicator species of wetland ecological environment changes, and is listed in the Red Book of Endangered Animals in China and the Red List of Endangered Species of IUCN. In 1992, two breeding grounds of black-billed gull were discovered for the first time in the Yellow River Delta Nature Reserve. Since then, its population has been expanding. The survey this spring showed that its breeding population exceeded 10,000 for the first time.

　　The reporter learned that the Yellow River Delta Nature Reserve is also the largest new wetland natural vegetation area along the coast of China, with 1,630 species of wild animals and 685 species of plants respectively. Xu Mingde, secretary of the Party Working Committee and director of the management committee of the nature reserve, said that they insisted on using an ecological approach to manage the ecology, and the wetland area of the nature reserve has increased by 12.3% and 188 square kilometers since 2017.

　　It is understood that the Yellow River Estuary National Park, which is integrated from eight nature reserves such as the Yellow River Delta Nature Reserve, has entered the stage of creation and implementation. In line with the goal of building the first land-sea integrated national park in China, the local government is solidly promoting a series of ecological protection and restoration projects to promote a healthier ecosystem and further enhance biodiversity.

??1905 movie network news Ada recently took publicity photos for a fashion program jointly organized by China and South Korea. Wearing a long black dress, she showed her beautiful legs, and her S-shaped curve was concave and convex. Her temperament was mysterious and elegant, but she also revealed some playful colors. She wrestled with South Korean actress Liu Renna at the recording scene of the program, and easily won the game, which was cheered and encouraged by the China players present. However, in the program broadcast a few days ago, only a picture of Liu Renna winning was played, which attracted controversy among fans and made them spit out God’s editing.

    Ada and Liu Renna naturally started the hostile mode as soon as they met in the program. In the program, Liu Renna admitted that he was very afraid of Ada. "This woman gives people a feeling of invulnerability, especially cold-blooded." In the arm-wrestling game that really ignited the desire to win or lose, when Sean and Zhang Chi both lost to the South Korean team, Ada, who claimed to be a "female man", showed strong confidence. After replacing high heels, she wore a low-cut dress and made preparations for the split, and prepared for the battle with an exaggerated A-shape, even more telling Liu Renna to get ready or she would really be sent directly to the hospital. Liu Renna, who has been shouting "fear", unexpectedly killed Ada in 3 seconds after proposing to change the venue.

Military guidance theory is the basic follow-up to lead military practice. Since the 18th National Congress of the Communist Party of China, General Secretary of the Supreme Leader, as the core of the Party, the commander-in-chief of the army and the leader of the people, has created and formed the thought of strengthening the army by the Supreme Leader with distinctive characteristics of the times and China characteristics in the magnificent military practice, and realized that the party’s military guiding theory keeps pace with the times again.

The supreme leader’s thought of strengthening the army has guided the construction of the people’s army in the new era and made historic achievements

Socialism with Chinese characteristics has entered a new era, so has national defense and army building. In the practice of governing the country, the General Secretary of the Supreme Leader led the people’s army to rebuild and rebuild in an all-round way, promoted the "four modernizations" of the army in an all-round way, and opened up a grand foundation to support the rejuvenation of a powerful country on the journey of strengthening the army and rejuvenating the army.

Military reform is extraordinary and a historic breakthrough has been achieved. Breaking and then standing, breaking and standing, and hoofing and stepping steadily are the distinctive features of our party building and army management in the new era. Facing the complicated and profound changes in the international situation and national security environment, and facing the institutional obstacles, structural contradictions and policy issues that have long restricted national defense and army building, General Secretary of the Supreme Leader made a strategic conclusion that "deepening the reform of national defense and army is the requirement of the times to realize the Chinese dream and the dream of strengthening the army, the only way to strengthen the army and the key measure to determine the future of the army". He personally led, personally designed and personally promoted the military reform in the overall deployment of the reform of the party and the state, initiated an unprecedented overall revolutionary change in the history of our army, and fought "three major battles." The first was the "above the neck" reform, which established the leadership and management system of "Central Military Commission-services-troops" and the operational command system of "Central Military Commission-war zone-troops", breaking the long-standing headquarters system, military region system and continental army system. The second is the "below the neck" reform, which reduces the number of military personnel by 300,000, greatly simplifies the non-combat institutions and personnel of the military, and implements the "army-brigade-battalion" system for the main combat troops, changing the long-standing land-based and homeland-defensive forces. The third is the military policy system reform, which systematically promotes the policy system reform in the four major areas of party building, strength application, strength building and military management, and establishes and improves Socialism with Chinese characteristics’s military policy system. The three reform campaigns are interlocking, and the people’s army has been completely transformed and has a new look.

The army building is extraordinary and a historic leap has taken place. In the face of the army’s long-standing abuses for a period of time, the Supreme Leader General Secretary gained insight into the problem from a political perspective, personally led the Gutian Army’s political work conference, set up a general plan for building the army politically, unswervingly promoted political training and consolidation, seriously investigated and dealt with serious cases of violation of discipline and law by senior cadres, completely eliminated the pernicious influence, and the people’s army was reborn from the ashes and the political ecology was fundamentally reversed. Promote the implementation of the strategy of strengthening the army through science and technology, seize the key of national defense science and technology innovation, establish the strategic basis of independent innovation, greatly strengthen basic research and original innovation, and realize the transformation of national defense science and technology and weapons and equipment construction from running side by side to running side by side. Promote the implementation of the strategy of strengthening the army with talents, build a new military talent training system, innovate military human resource management, and recruit outstanding talents from all walks of life to join the cause of strengthening the army. Grasp the core and foundation of all the work of the army, grasp the leadership and party building work of the army, and promote the grassroots construction of the people’s army to make great progress. We will step up efforts to administer the army according to law and strictly manage the military, speed up the construction of a military legal system with China characteristics, continue to rectify the "four winds" and the "Five-odd" problems, and promote the gradual and fundamental transformation of the way of administering the army. The "combination boxing" formed by a series of major measures has made a comprehensive situation and a long-term trend, which has continuously improved the quality and efficiency of people’s army building in the new era.

The military struggle was extraordinary and achieved historic results. Since the 18th National Congress of the Communist Party of China, new complex and profound changes have taken place in the international pattern. The General Secretary of the Supreme Leader has profoundly grasped the general trend of national security, engaged in relations among major powers, led the people’s army to calmly respond, firmly grasped the opportunities of military competition, and always controlled the initiative of military struggle. The preparations for military struggle have taken on a new look. Leaders formulate military strategic guidelines for the new era, strengthen the overall guidance of military struggle, focus on winning battles, make in-depth preparations for fighting in all directions and fields, and be vigorous and promising in expanding the depth of active defense strategy, accelerating the military forces to go abroad, and managing new security fields. Command a series of major military operations, effectively resolve possible war risks, earnestly safeguard national sovereignty, security and development interests, boost national prestige and military prestige, and enhance national self-confidence and pride.

The supreme leader’s thought of strengthening the army is the latest achievement of the Communist Party of China (CPC)’s military guidance theory advancing with the times

The supreme leader’s thought of strengthening the army made profound strategic thinking on all aspects of national defense and army building, made scientific and long-term strategic plans, and profoundly expounded a series of fundamental issues such as the goal direction, mission, strategic layout, fundamental direction and important path of strengthening the army, forming a scientific theoretical system with rich ideological connotation and profound implications.

Focus on rejuvenating the country and make a new summary of the goals of the people’s army. The supreme leader’s thought of strengthening the army points out that the party’s goal of strengthening the army in the new era is to build a people’s army that listens to the party’s command, can win battles and has a good work style. It must be consistent with the process of national modernization, and strive to basically realize the modernization of national defense and the army by 2035, and build the people’s army into a world-class army in an all-round way by the middle of this century. This profoundly answered the question of what kind of people’s army to build in the new era and laid the "theoretical cornerstone" of the supreme leader’s thought of strengthening the army in one fell swoop. In the practice of building and managing the army, the general secretary of the supreme leader’s exposition on the goal of strengthening the army has been developing continuously, especially the 19th National Congress of the Communist Party of China has made new strategic arrangements for comprehensively promoting national defense and army modernization. The Fifth Plenary Session of the 19th CPC Central Committee proposed to speed up the modernization of national defense and the army, and ensure the realization of the centennial goal of building the army in 2027, which further pointed out where the people’s army will go and where it will develop, and made clear the goal direction for the people’s army to break the waves on a new journey.

Focus on great struggle, keep pace with the times and innovate military strategic guidance. The supreme leader’s thought of strengthening the army profoundly expounds that strengthening the country and the army must be strategic first, and clearly points out that the strategic goal of the party and the country is to achieve the goal of "two hundred years" and realize the great rejuvenation of the Chinese nation at present and for a long time to come. Innovative development of military strategic guidance must firmly grasp this fundamental focus, strengthen military strategic operation and improve the level of military strategic guidance. This military strategy is a general plan to take the overall situation into consideration, balance the opponents and win the war. Its spiritual essence is to ensure that the army effectively performs the mission entrusted by the party and the people, and provide strategic support for consolidating the Communist Party of China (CPC)’s leadership and socialist system, defending national sovereignty, unity and territorial integrity, safeguarding national overseas interests and promoting world peace and development.

Strengthen the Party’s absolute leadership over the people’s army with an eye on the eternal stability of the country. The supreme leader’s thought of strengthening the army emphasizes that the party’s absolute leadership over the army is the foundation of the people’s army and the soul of strengthening the army. It is necessary to comprehensively implement a series of fundamental principles and systems of the party’s leadership over the army to ensure the absolute loyalty, purity and reliability of the army. Adhering to the party’s absolute leadership over the people’s army at the 19th National Congress of the Communist Party of China is defined as a basic strategy for upholding and developing Socialism with Chinese characteristics in the new era. The Fourth Plenary Session of the 19th Central Committee of the Communist Party of China regards "upholding the party’s command of guns and ensuring the people’s army’s absolute loyalty to the party and the people" as a remarkable advantage of the national system and the national governance system, and clearly proposes to uphold and improve the party’s absolute leadership over the people’s army. The implementation of the chairman responsibility system in the Central Military Commission is the fundamental form of upholding the party’s absolute leadership over the people’s army. The highest leadership and command of the army belongs to the CPC Central Committee and the Central Military Commission, and the national armed forces are under the unified leadership and command of the chairman of the Military Commission. All these are significant theoretical and political contributions, which indicate that Socialism with Chinese characteristics’s basic military system is more mature and stereotyped.

Focus on the overall situation of the cause and creatively optimize the layout of strengthening the army. The supreme leader’s thought of strengthening the army puts the army construction in the overall situation of the party and the state, thinking, planning and scientific deployment. From "deepening the political army building, reforming and strengthening the army, and managing the army according to law" to "persisting in the political army building, reforming and strengthening the army, managing the army according to law" and then "persisting in the political army building, reforming and strengthening the army, strengthening the army through science and technology, strengthening the army with talents and managing the army according to law", the layout of strengthening the army has been continuously expanded and optimized. This layout of strengthening the army is the embodiment of our party’s strategic layout of governing the country and politics in the new era in the military field. It has grasped the strategic key issues supporting the strengthening of the army, defined the fundamental guarantee, key move, powerful motivation, strategic resources and the guarantee of the rule of law for strengthening the army, and set up a four-pillar, eight-pillar and backbone framework for the cause of strengthening the army.

Focus on winning the battle and comprehensively strengthen training and preparation. The inherent characteristic of military guidance theory is to seek and win. The supreme leader’s thought of strengthening the army emphasizes that the army should prepare for war, and must comprehensively improve its ability to prepare for war in the new era, effectively shape the situation, control the crisis, contain the war and win the war. These expositions reveal the fundamental direction of strengthening the army in the new era and constitute the "theoretical core" of the supreme leader’s thought of strengthening the army. The army is born of war, and the preparation for military struggle is the basic practical activity of the army. The supreme leader’s thought of strengthening the army clearly puts forward the only fundamental standard of firmly establishing combat effectiveness, which requires that the combat effectiveness standard should run through the whole process and all aspects of army building, pay great attention to actual military training, make solid preparations for military struggles in all directions and fields, gather together to build elite combat forces, and carry forward the fighting spirit of not being afraid of hardships and not being afraid of death. These important expositions are of great significance for correcting the center of gravity and direction of army building and development, forming a direction that all minds focus on fighting and all work focuses on fighting hard, and promoting the people’s army to fully leap forward in winning the war.

Focus on enriching the country and strengthening the army, and promote the simultaneous improvement of national defense strength and economic strength. Dealing with the relationship between the coordinated development of national defense construction and economic construction is a common topic in the governance of great powers at all times and at all times, including both profound lessons and good experiences. The supreme leader’s thought of strengthening the army integrates national defense and army building into the national economic and social development system, and emphasizes the combination of development and security, economic construction and national defense construction, the unification of enriching the country and strengthening the army, making full use of all superior forces and resources to build an integrated national strategic system and capability. In the new era, the cause of strengthening the military is rooted in the deep soil of the rapid development of the country’s economy and society. With the strong strength of the country’s economy and science and technology, and the majestic strength of the whole society, the modernization of national defense and the military will surely add wings and advance by leaps and bounds.

The supreme leader’s thought of strengthening the army is a vivid Marxist military theory in the 21st century.

In the new era, which is a special historical period of great changes in the world, great development of the country and great military competition, the supreme leader’s thought of strengthening the army applies Marxism to observe and reflect China’s military practice, reveals and reflects the objective laws of military activities in the world today, and makes great original contributions to enriching and developing Marxist military theory. This thought not only adheres to the basic viewpoints of Marxism on war and military issues, but also adheres to our party’s consistent guiding ideology and major principles for building and managing the army. It also closely combines the characteristics of the new era and practical development, absorbs the essence of Chinese excellent traditional military culture, draws on the outstanding achievements of world military theory, sublates scientific theories, and forms the achievements of military civilization with China style and China style.

The supreme leader’s thought of strengthening the army profoundly answered the question of the times when a strong country must strengthen the army. To cope with the great changes in the world in the past century and ensure that China is invincible in the fierce international military competition, it is required that the army must accelerate the transformation from a "big country army" to a "powerful country army." At present, the international strategic pattern is deeply adjusted, and the overall competition and overall contest between countries are more prominent. The more complicated the situation, the better the military skill. At present, national security is facing one kind or another of risk challenges, the possibility of war and chaos at home is real, and the task of safeguarding national unity and social stability is arduous and arduous. We must dare and be good at carrying out great struggles with many new historical characteristics. A strong army is an inherent requirement and an important symbol of a strong country. A strong army is needed to deter and stop the war, and a strong army is needed to provide support for the country’s prosperity and development. The supreme leader’s thought of strengthening the army focused on strengthening the army and put forward many strategic and original ideas, comprehensively and systematically answered the historical and epochal topic of supporting the country with strengthening the army, and opened up a new realm of China-ization of Marxist military theory.

The supreme leader’s thought of strengthening the army further enriched the party’s military guidance theory treasure house. The Communist Party of China (CPC)’s military guidance theory is a scientific summary of the practical experience of China’s revolutionary war, people’s army and national defense construction, and the crystallization of the collective wisdom of the whole party and army. It is in the same strain and keeps pace with the times with the changes of the times and the development of practice. Our party has gone through a hundred years of struggle, and in the course of commanding guns by the party, it has successively formed Marxist military theoretical achievements with China characteristics, such as Mao Zedong’s military thought, Deng Xiaoping’s army building thought in the new period, Jiang Zemin’s national defense and army building thought, and Hu Jintao’s national defense and army building thought. Based on Do not forget your initiative mind’s political consciousness and radical theory, the supreme leader’s thought of strengthening the army scientifically summarizes the basic experience of our army’s construction and development, profoundly reveals where the people’s army came from and why it went from victory to victory, and at the same time puts forward a series of new ideas, new ideas, new theories and new requirements in response to the needs of the new era, realizing a major breakthrough and innovation in the party’s military guidance theory, and highlighting the political and theoretical inheritance of the Communist Party of China (CPC) people in the past 100 years.

The supreme leader’s thought of strengthening the army shines with the truth of dialectical materialism and historical materialism throughout. The supreme leader’s thought of strengthening the army has a keen insight into the contradictory movements in the military field in the new era, and has made a series of new explanations on the relationship of unity of opposites, such as war and peace, military and politics, development and security, change and new situation, crisis and initiative, preparation and stop of war, deterrence and actual combat, and man and weapons, which profoundly reveals the way to strengthen the army and win in the new era, with broad vision, lofty ideas and vigorous weather, and embodies the basic principles and science of Marxism. The supreme leader’s thought of strengthening the army runs through the mission based on far-reaching history, which contains conscious understanding of historical position, firm adherence to revolutionary feelings and determined pursuit of ideal goals, showing the ideological style and lofty realm of contemporary the Communist Party of China (CPC) people; Through the epistemological methodology of grasping the military and building the army around politics, we put the war issue in the realization of the great goal of national rejuvenation, promote national defense and army building as a whole from the overall situation of the party and the state, and guide military actions with the overall situation of national politics, diplomacy, national security and strategy, enriching and developing the Marxist military view of war; Through the revolutionary style of seeking truth from facts and building the army by hard work, the Marxist practical viewpoint and the party’s ideological line of seeking truth from facts are applied to the military field, which sets an example for thoroughly eliminating problems and opening up new prospects for the cause and provides methods and guarantees for turning the blueprint for strengthening the army in the new era into reality; Throughout the sense of urgency of looking to the future and preventing in advance, we are always ready to carry out new great struggles.Fight a well-prepared battle to prevent and resist risks, and fight a strategic initiative to turn danger into opportunity; Through the enterprising spirit of being proactive and determined to develop, it embodies the strategic enterprising view of taking the initiative, the struggle art of sticking to the bottom line and daring to show the sword, and the innovative character of relying on scientific and technological development and progress, and so on. All this is condensed with profound theoretical practicality and distinct strategic foresight, and shows the wisdom and strength of Marxist military theory in the new era.

　　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 annual Tomb-Sweeping Day is coming. Do you plan to go back to your hometown to visit graves and pay homage to your ancestors? Go for a walk to sweep graves, burn paper money, set off firecrackers, and eat green mugs … … It has always been a tradition in Tomb-Sweeping Day, China to offer sacrifices to the dead and mourn for the living. In foreign countries, many countries also have such a special day, with a variety of festivals and ceremonies, to pin their grief on the deceased relatives and friends and martyrs. So, when is the "Tomb-Sweeping Day" abroad? In what ways will they commemorate their ancestors and express their thoughts? Let’s take a look at the best "Tomb-Sweeping Day" abroad!

　　The most patriotic "Tomb-Sweeping Day": the United States, Israelis and Tanzanians.

　　American "fallen soldier’s day" shows people’s love for their country.

　　Memorial Day in the United States is to mourn the American soldiers killed in various wars. It was designated as a national holiday by the federal government in 1971, and the date is the last Monday in May. At first, people only paid homage to all the war victims on the "Memorial Day", and later it gradually evolved into a general family to pay homage to their deceased relatives.

　　Memorial Day is not only an important festival to show patriotism to Americans, but also represents the official start of summer among the people. Many beaches, amusement parks, summer ferries on small islands, etc. will start to operate from the weekend of that week. Due to the three-day holiday in a row, many Americans went to the suburbs for a barbecue, went to the seaside to have fun or visited museums, etc., resulting in serious traffic congestion.

　　Israel: mourning for a series of national anniversaries

　　On April 15th, 2015, Israel held an annual memorial ceremony for the victims of the Holocaust at Yad Wehim Holocaust Memorial Hall in Jerusalem.

　　The Israeli people continuously commemorate the Holocaust Remembrance Day, the Martyrs’ Remembrance Day and Israel’s National Independence Day around May of the Gregorian calendar every year. The anniversary of the Israeli Holocaust is determined according to the Jewish calendar, and it varies from year to year according to the AD calendar.

　　As the Palestinian-Israeli conflict continues, causing great casualties to Israel, these seemingly official festivals are actually directly connected with the feelings of thousands of families in Israel. Whenever these days come, Israelis will come to the graves of their relatives with flowers and candles in their hands, and use the unique customs of the Jewish nation — — Put stones symbolizing eternity on the tombstones of relatives to express their inner grief. Many tombstones are laid flat, so that there can be a larger area on the tombstones to carry the stones entrusted by relatives and friends.

　　Tanzania: "Mourning Festival" mourns the martyrs of the War of Independence.

　　Tanzania is one of the cradles of ancient humans. In the 7th-8th century, Arabs and Persians moved into this area, and in the 19th century, colonial forces from Germany and Britain invaded one after another. In order to strive for independence, the Tanzanian people waged a heroic struggle with the colonists. In 1961, Tanganyika declared independence, in December 1963, Zanzibar declared independence, and in 1964, the two formed a United Republic, which was renamed the United Republic of Tanzania in October of the same year.

　　In order to mourn the martyrs who died for their country in the War of Independence, the Tanzanian people designated September 2nd every year as "Mourning Day". On this day, people voluntarily go to the cemetery to offer flowers and sweep the graves. National leaders also visit the Martyrs Cemetery to pay homage, and some people also offer wreaths in front of the monument in Independence Square to express their grief for the martyrs.

　　The most environmentally friendly "Tomb-Sweeping Day": Singaporean and Russian.

　　Russia: Painting eggs in front of the tomb with fake flowers instead of real receptacle mourning

　　Every year from the end of April to the beginning of May, Russians visit the graves of their deceased relatives with their families. This festival is Russia’s Day of Remembrance of the Dead. The name of Memorial Day in Russian is "Radonica", which literally shows no sadness. According to Russian linguists’ research, the name comes from the words "birth" and "happiness". This festival is specially arranged after Easter, so that people should not be sad for the loss of their loved ones, but should be glad for them to rest in another world.

　　On the Day of Remembrance of the Dead, Russians will visit the graves of their deceased relatives and pay homage to them. According to the traditional custom, they will offer eggs painted with colorful patterns in front of the tomb, which is said to pray for the blessing of the dead. In addition, they will also provide food such as sweet milk cake, pie and fruit soup, and plant flowers and plants around the cemetery. After the memorial service, the whole family will have a simple dinner in front of the tomb. Everyone will drink a glass of vodka, but they can’t touch glasses or talk when drinking. Devout Orthodox believers go to the church to light candles for the deceased before going to the cemetery, pray for the soul of the deceased to rest in peace, and collect holy water and sprinkle it in front of the cemetery. Today, some details of the memorial ceremony have changed. For example, in the past, Russians placed flowers in front of cemeteries, but now they use more and more beautifully made fake flowers. On the one hand, fake flowers can last longer, and on the other hand, fake flowers are relatively cheaper than real flowers.

　　Singapore: government-customized incineration barrels are easy to clean.

　　Compared with Tomb-Sweeping Day, Chinese Singaporeans pay more attention to the "Mid-Yuan Festival" on July 15th of the lunar calendar every year. Legend has it that all ghosts were released in the underworld on that day, and people generally carried out activities of offering sacrifices to ghosts. In order not to affect hygiene and facilitate cleaning, Singapore’s incineration barrels are customized by the government and placed in front of the house every July for people to burn paper.

　　There is also a special performance in the Chinese-speaking areas of Singapore to entertain ghosts, which the local Fujian people call "July Song Tai" or "Song Tai" for short. Generally speaking, a singing stage is set up on an open space, decorated with audio equipment and lighting, and rows of chairs are placed in the audience, while the chairs in the first row are usually vacant and reserved for "good brothers" (ghosts). Stage performances are usually arranged at night, including humorous short plays, magic, strong songs and dances, etc., and performances are held throughout the seventh month of the lunar calendar.

　　The happiest "Tomb-Sweeping Day": Philippine, Mexican.

　　Philippines: Set up tents and sing K-style family gatherings.

　　On November 1, 2008, in a cemetery in Manila, the capital of the Philippines, a boy was cleaning up the tombstones of his relatives.

　　Filipinos usually sweep graves for their deceased relatives on Halloween and All Souls’ Day every autumn. They will set up tents in cemeteries for the night and hold various entertainment activities to remember their loved ones in a happy atmosphere. Halloween and All Souls’ Day are the most popular days of the year in the Philippines. On the day before Halloween, the grave keeper will clean the cemetery and the surrounding roads to welcome grave sweepers. On Halloween, many people rushed to the cemetery and set up tents for the night.

　　When sweeping graves, Filipinos will not only offer flowers and sacrifices to their deceased relatives, but also prepare food and various entertainment activities for themselves. At the graves of relatives, some people pray, some cook, some play poker, some play guitar, and some even sing karaoke, as if they were holding a lively family gathering. A Philippine media commented that Halloween and All Souls’ Day are not only festivals for the dead, but also festivals for the living.

　　Mexico: Celebration to welcome the dead home is included in the intangible heritage.

　　Mexico’s Day of the Dead is divided into two days. Every year, November 1st is the "Young Spirit Day" to pay homage to the dead children, and November 2nd is the "Soul Festival" to pay tribute to the dead adults. At this time, Mexicans will set up altars at home, filled with flowers, candy, decorations, etc., to welcome their deceased relatives home, or set up banquets in cemeteries, play music and wait for celebrations all night. Mexican aborigines believe that death is not a sad thing, but should welcome the dead home with songs and dances and colorful celebrations.

　　The Day of the Dead originated from the ancient Mexican indigenous Indian culture. After the Spanish came to the New World in the 16th century, the Western Catholic Halloween was combined with the ancient Indian tradition of offering sacrifices to the dead, thus gradually forming today’s Day of the Dead. In 2003, UNESCO listed Mexico Day for the Dead as an intangible cultural heritage. Although Mexico’s "Day of the Dead" is similar to other western countries, it essentially inherits the Indian tradition and shows Indian cultural characteristics, as well as their unique humor and ideas about life and death. In their view, death is not the end of life. The dead will go to another happy world and enjoy the beginning of a new life.

　　The most religious "Tomb-Sweeping Day": Cambodian and Polish.

　　Cambodia: It is an important activity to go to the temple to sacrifice the dead.

　　Buddhism is the main religion in Cambodia, so the "Tomb-Sweeping Day" in Cambodia is also very religious. The Day of the Dead, held from October 1 to 15 in the Buddhist calendar every year, is the most solemn festival in Cambodia, with the theme of remembering the dead and worshiping the ancestors. The content of the Day of the Dead is very rich. Every family will go out for an outing, have a picnic, visit relatives and friends while paying homage to their ancestors, and various activities will be held in various places, such as buffalo race, wrestling competition, stick performance and so on.

　　Sacrifice in the temple is the most important activity of the Day of the Dead. At that time, every household should bring sacrifices and go to the temple to worship, and almost all Buddhist temples, big or small, will be full. If possible, they will take food to Buddhist temples every day, and some people can even go to three or four Buddhist temples to give alms in one morning; If there are no conditions, you can only go to one or two Buddhist temples once or twice in 15 days, but you must go. According to the Khmer national tradition, the more Buddhist temples you go to, the more merits you accumulate.

　　Poland: Mass to pray for the dead

　　November 2nd every year is a traditional festival for Poles to remember the dead, which is called Day of the Dead, and it follows Halloween on November 1st. Today, in Poland, the memorial activities for the dead are mainly concentrated on November 1. On this day, people go to the cemetery to sweep graves, and the elderly light candles symbolizing the immortality of the deceased, so that children can offer them sacrifices to educate future generations not to forget their ancestors. They will also display bouquets, baskets or other decorations to commemorate their old friends.

　　According to the traditional explanation of Poland, the Day of the Dead began to spread in the 12th century, and it was not accepted by people all over the country until the end of 15th century. Besides sweeping graves, Poles also go to mass and pray for the dead. (Text Image Source: Xinhuanet, Overseas Network Editor: Tian Ming, Intern Li Xia)
