On the evening of December 27, the Long March 5 remote three carrier rocket was successfully launched. Guo Wenbin/photo

　　Qian Xuesen, known as the father of China Aerospace, once said: If scientific experiments can be successful every time, then why experiment? After setbacks and failures, we will become smarter.

　　The "Phoenix Nirvana" trip of the Long March 5 is the best example at present.

　　Two years ago, the second launch of the Long March 5 was defeated. This news hung over the hearts of Chinese people like a haze, and once caused doubts. Today, the largest rocket in China has been reborn for more than 900 days, and it has gone out again.

　　On December 27th, the Long March 5 started its third flight at Wenchang Space Launch Site, accompanied by a roar that shook the mountains. A dazzling flame surrounded the big rocket and flew out of the sky. In the end, the mission was declared successful, and this big rocket was dormant for two years, and finally it was proud!

　　Behind the soaring, it can be described as "twists and turns". In the words of Long Lehao, academician of China Academy of Engineering and chief designer of Long March series rockets of the First Academy of China Aerospace Science and Technology Corporation, "Failure is almost success, and success is almost failure" — — Over the past two years, more than 900 days and nights, China astronauts dare not take it lightly every moment.

　　Soul-stirring 2 hours and 43 minutes

　　Long March 5 is a rocket destined to be extraordinary from birth, which has entrusted too many people’s dreams and long-cherished wishes. For a long time, when it comes to the development of a certain technology or a certain field in China, people have become accustomed to using "big but not strong" to describe it. But aerospace is breaking this statement, and the first punch to break this statement is the Long March 5 — — It is equivalent to the admission ticket of a "space power". Its development difficulty can be imagined.

　　As early as 1986, the demonstration of a new generation of launch vehicles was carried out in China. Since the mid-1990s, the research on a new generation of rocket engines has been put on the agenda. In 2016, a new generation of big rockets developed after 30 years of demonstration — — The first flight of Long March 5 was successful, which attracted much attention.

　　However, behind the success of the first flight, there was also an episode of "almost failure".

　　Hu Xudong was the commander of the first flight mission 01 of the Long March 5. He still remembers that it was November 3, 2016, and the launch time was postponed from 18: 00 to 20: 43. In the meantime, it experienced six suffocating time resets, and even faced the test that the launch mission was forced to cancel.

　　People who watched the launch thus remembered the special moment of "near misses" and gained a somewhat more intuitive understanding of this rocket, which kicked off the era of China Grand Carrier.

　　When the time was set back to 17: 30 on the same day, the atmosphere in the test hall suddenly became tense, and hundreds of scientific and technological personnel looked at the big screen together — — The rocket "has a fever" because the primary circulation precooling pump of the rocket can’t be started normally. At the moment, the temperature displayed on the big screen is 238K, which is much higher than the take-off standard of 110K … …

　　According to Hu Xudong’s recollection, at this time, the mission headquarters decided that if the pre-cooling effect of the engine could not meet the launch conditions by 19: 30, the propellant leakage procedure would be started and the launch mission would be cancelled.

　　At 19: 28, there were only two minutes left from the "bottom line", the engine temperature dropped to a predetermined value, and the rocket successfully "cooled down".

　　"Set the ignition time to 20: 40." Hu Xudong exhaled a sigh of relief greatly. However, even at the last minute before the launch, emergencies have occurred again and again.

　　At 20: 40, only one minute left before the final launch, Hu Xudong just issued the password of "1 minute preparation", and suddenly heard Wei Kang, the commander of the control system, issue "the most awesome password in China’s space history": "01, stop launching!"

　　"What’s the matter?"

　　At this moment, Hu Xudong involuntarily stood up and blurted out 1.

　　Ten seconds before the launch, Hu Xudong began to count down, and suddenly he received a request from Wei Kang "Please wait a moment".

　　"Stop the launch!" Hu Xudong stopped emission process, and once again organized the troubleshooting. The problem was finally solved.

　　The "ignition" password was finally issued and the rocket took off.

　　Behind the cheers, astronauts including Hu Xudong began to sort out and analyze the launch data, and they had to face 630,000 original data — — These are related to whether China Rocket can still "turn the corner" next time.

　　Guess the beginning but not the ending.

　　Long Lehao was on the scene for the first two launch missions of Long March 5. One of his obvious feelings is that although the first launch mission was successful, the "stumbling" three hours before takeoff seems to be more touching. He said: "This is inevitable. After all, this is a brand-new rocket and the situation is too complicated."

　　Accordingly, the second launch, for many people at the scene, "was originally very smooth." "Before taking off, it was not as thrilling as the Long March 5 Yaoyi (the first flight mission, reporter’s note, the same below)." Long Lehao said that the launch site of Yaoer was "much calmer" and "much better" in the first few minutes.

　　At that time, he was still thinking, "This may be the first tortuous experience, exposing some problems, and then doing a lot of improvement work, having experience and a relatively stable mentality."

　　Indeed, after the Long March 5 took off from Wenchang Space Launch Site for the second time, everything was normal in the first few minutes. But after flying for more than 300 seconds, the problem appeared.

　　"All of a sudden, the flight curve of [Long March 5] is not quite right … …” In the test hall of Wenchang Space Launch Site, Long Lehao saw from the big screen that the curve was not going up in their predetermined direction, but was "falling" down.

　　His mind is tight: the flight curve falls, which means that the rocket is gradually losing thrust. If the thrust is not enough, the rocket will have no acceleration and will not be able to overcome the gravity field.

　　"At that time, I had a presentiment that ‘ It’s over ’ This launch is going to fail … …” Long Lehao said.

　　The measuring hall was silent.

　　A monitoring team member at the scene told reporters that their hearts, like the flight curve on the big screen, "kept falling", and many people silently shed tears.

　　That night, Xinhua News Agency released the news of mission failure.

　　"This result is what no one wants to see." Long Lehao said that he soon told himself that the failure of scientific experiments was inevitable. What we need to do now is how to find out the cause of the failure as soon as possible, take measures, try to go around as soon as possible, and prove once again that our rocket is trustworthy with practical actions.

　　That night, when Long Lehao left the test hall, he didn’t have much communication with the space junior on the spot. But he believes that these young astronauts have the ability to withstand the pressure. "Now it does seem that they are not overwhelmed by difficulties — — Get down and still stand up! " Long Lehao said.

　　What’s the problem with the engine again?

　　On April 16, 2018, the National Space Administration released the investigation on the failure of the Long March 5 remote rocket, which mentioned that the Long March 5 remote rocket suddenly failed when it flew to 346 seconds.

　　The cause of the failure is that the turbine exhaust device of the first unit of the core-stage liquid hydrogen and liquid oxygen engine is abnormal in the local structure under the complex mechanical and thermal environment, and the engine thrust drops sharply instantly, resulting in the failure of the launch mission.

　　Engine is also an engine. Yes, this word, which once stung the Chinese people’s key technology in the aviation field, has become a stumbling block in the aerospace field this time.

　　A big rocket is naturally inseparable from a big thrust, and a big thrust is inseparable from the development motivation. Before the Long March 5, the maximum thrust of a single rocket engine in active service in China was only about 70 tons, so it was "inadequate" to launch a very large spacecraft.

　　A new type of high thrust engine came into being. According to Zhou Limin, secretary of the Party Committee of the Sixth Academy of China Aerospace Science and Technology Corporation, after 15 years of unremitting research, eight newly developed 120-ton liquid oxygen kerosene engines were assembled on the four boosters of the Long March 5, and four newly developed hydrogen-oxygen engines were assembled on the first-class and second-class rockets.

　　He has an image saying that developing an engine is as difficult as climbing Mount Everest. "Some foreign experts say that even if we design it, we can’t make it." Among them, the hydrogen-oxygen engine that failed in the remote second mission is even more difficult.

　　Zhou Limin still remembers that in the face of brand-new engines, the research team began to tackle scientific and technological problems day and night, and dozens of new materials and more than 100 new processes were overcome one by one. However, the starting of the engine has become the biggest obstacle.

　　He said that in the starting stage, the whole engine is in an unstable dynamic process, because the speed changes from a static state to tens of thousands of revolutions, and the temperature changes from a low temperature state to a high temperature state. Our control sequence is controlled in milliseconds, and any action that is not well coordinated and fails to achieve the expected result may lead to failure.

　　At first, the development team was hit hard. After the prototype of the engine used in the first flight of Long March 5 was developed, its test results failed four times in a row: two starting explosions and two burning gas systems.

　　Zhou Limin said that these have dealt a great blow to the confidence of the entire research and development team and design team. "Many people dream of the explosion scene in their dreams, and they can’t eat or sleep well."

　　Find out the "devil" and destroy the "enemy"

　　And these are just the "pains" that China astronauts encountered in the engine development stage. After the failure of the Long March 5 Tele-2 mission, the pressure faced by these people became even greater, and they even called the faulty engine problem "the devil".

　　A test team member of the Sixth Academy of China Aerospace Science and Technology Corporation told the reporter that in order to find out the "devil" and destroy the "enemy", the development team has suffered unprecedented hardships, hardships, twists and turns and doubts in the past two years. The experience of tempering, struggling, struggling and tackling key problems is also rare in the history of development. Especially those "demons" who are hidden deep, the tension and complexity of the battle are unprecedented.

　　“‘ Devil ’ It pops up from time to time, blinding the development team’s sight, and even pushing them into the endless abyss of opaque. However, the development team was not intimidated by the darkness and was not defeated. " Zhou Limin said.

　　According to the statistics of the Sixth Academy of China Aerospace Science and Technology Corporation, in the second and third quarters of 2019 alone, the development teams of 11 hydrogen-oxygen engines in Beijing of the Academy worked overtime for 23,000 hours, and finally found out the "devil" hidden in the engine and eliminated the "enemy" who was recalcitrant, eliminating hidden dangers and eliminating faults.

　　Li Dong, the chief designer of the Long March 5 rocket, told the reporter that after the failure of the Long March 5 rocket, after more than 100 days of troubleshooting and positioning, and more than 180 days of experimental verification, the reason for the failure was finally confirmed. After that, according to the conclusion of fault investigation, the development team improved the design of the first-stage hydrogen-oxygen engine, and adopted corresponding improvement measures from the aspects of structure, materials and technology, which improved the adaptability to the flight environment.

　　The cause of the failure was found, identified and improved. Everything seems so smooth.

　　However, new problems have come again.

　　The process of returning to zero is full of twists and turns

　　On November 30, 2018, the improved core-stage hydrogen-oxygen engine had problems during the long-distance test run.

　　Li Dong told reporters that this time the astronauts responded faster. According to the cause of the failure, the development team improved the local weak links of the engine and improved the dynamic strength margin of the structure.

　　On March 29, 2019, the zeroing work and improvement verification of engine test failure were all completed — — The two long-distance test runs passed successfully, and the second problem was solved in this way.

　　But soon, they ushered in the third "encounter."

　　On April 4, 2019, when the final assembly of the Long March 5 remote three rocket entered the final stage, an "abnormal vibration frequency" appeared in the process of analyzing the test data of a core-stage hydrogen-oxygen engine used for subsequent tasks.

　　It can be described as twists and turns, once again verifying that sentence: the road to scientific exploration has never been smooth.

　　"Without a trace of doubt!" Li Dong said that the developers followed the trail and found the crux of the problem — — The local structure of the engine is very sensitive to the complex mechanical and thermal environment, and it is easy to cause resonance. Once excited, it is not easy to decay.

　　In July 2019, the developers completed the structural improvement of the engine and completed more than a dozen large-scale ground tests.

　　At this point, the engine problem that has plagued the Long March 5 for more than two years has finally been investigated.

　　According to the statistics of the First Academy of China Aerospace Science and Technology Corporation, the Long March 5 was defeated by Yaoer on July 2, 2017 and successfully launched by Yaosan on December 27, 2019, which lasted for 908 days and carried out more than 40 key technical tests.

　　After 908 days and nights, I got up again after countless falls. And the biggest "hard bone" — — The hydrogen-oxygen engine has also completed the phoenix bath fire and nirvana rebirth in more than two years.

　　According to Long Lehao, more than 900 days, such an interval — — It is a long time in the history of the Long March rocket to go beyond the period of the follow-up flight after the mission fails. In his impression, there is not even a "return to zero" at such a long interval.

　　"We certainly hope that the interval will be shorter, but scientific research cannot change with subjective wishes." Long Lehao said that the failure of the Long March 5 rocket was due to the failure of a certain engine component under the interaction of complex mechanical and thermal environment — — This problem is deeply hidden, and it does not appear in most cases, but only occasionally. However, once it appears, it is a "disastrous result".

　　In his view, this "zeroing" finally caught this mischievous "devil", although it took a long time, it was worth it.

　　"We’re all suffocating."

　　In fact, it takes more than a few teams to find out the "devil" and "rebuild" the engine.

　　Yan Yong, deputy director of Beijing No.11 Institute of the Sixth Academy of China Aerospace Science and Technology Corporation, told the reporter that the failure to launch the Long March V Remote II rocket pushed the liquid power industry with the reputation of "golden power" to the forefront, and the failure of the first-class high-thrust hydrogen-oxygen rocket engine put the engine development team under tremendous pressure and test. With the help of the strength of the Group and the Sixth Hospital, the Institute has used all effective resources to carry out the zeroing work — — It can be said that this is a "national alliance" to tackle key technical problems.

　　"It’s the first time I’ve seen so many academicians get together!" Lv Wei, the quality supervisor of 11 universities in Beijing, said that he was most impressed by the evaluation. Twenty-five academicians and five university professors came to the site as invited experts to listen to the engine development work and put forward opinions and suggestions. Nearly 60 leading experts in the system also participated in the exchange and discussion.

　　In fact, after the failure of the mission two years ago, many people are also eager to try, looking forward to returning to the "battlefield" and showing their talents.

　　"If setbacks obscure the light of the road ahead, then use the unrepentant heart to light the fire at night!" Chen Jiwei, commander of the launching station system at Wenchang Space Launch Site, told the reporter that there was no frustration and discouragement, and everyone held their breath. All systems and posts rallied from scratch and immediately put themselves into the preparations for the rocket’s go-around.

　　Deduct the process again and again, anticipate and recall one by one, and operate the exercise again and again. The operation of the air compressor of a system in the station is not very stable, and the equipment manufacturer has repeatedly made dozens of improvement tests, but the problem still exists.

　　Many people have advised Chen Jiwei, "it’s not a restrictive factor, it’s almost enough." However, his answer is adamant. "The factors that affect the task must be solved without compromise!"

　　Today, the Long March V has finally won this "turn-over battle", and it has become the most iconic task of China Aerospace in 2019. This is not only because it determines the implementation of major engineering tasks such as the follow-up Chang ‘e V, manned space station and the first Mars exploration, but also because it presents the process of scientific experiments from failure to success to the public in such an intuitive way, which makes people feel moved and amazed.

　　In addition to Qian Xuesen’s sentence, Albert Einstein also had a "golden sentence" that was regarded as a standard by the scientific community. The general idea is that it is not a bad thing for a person to take detours and make mistakes on the road of scientific exploration, and it is not a shame. It is necessary to bravely admit and correct mistakes in practice.

　　Long March 5 did it. China astronauts did it.

"We are like Apple in 1984, ‘when Apple had the revolutionary power to break IBM’s monopoly on the computing technology market.’ But now, ‘Apple is the behemoth it once accused of trying to control markets, stifle competition and stifle innovation.’"

The new payment system undoubtedly violated Apple’s App Store policies, and Apple responded quickly and aggressively by removing Fortnite entirely from the App Store. Epic was clearly well-prepared. Shortly after being taken down, Epic released a small video of "Fortnite", in which it mocked Apple from a former dragon slayer to a dragon, borrowing a meme from Apple’s famous 1984 MAC ad.

The classic 1984 Apple ad was about revolution and breaking IBM’s monopoly. But the video was more than a satire. Minutes after the video was released, Epic announced that it had filed a lawsuit against Apple.

The rivalry between the two sides is still escalating. Apple has taken down Epic’s developer account and iOS and MAC power builder. Epic claims this will prevent them from developing software for Apple’s platform, including Unreal Engine support for third-party developers on the iOS.

However, according to an annual survey called "All Things Valve Should Know 3.0": Since 2018, game developers, especially in the West, have become increasingly negative about Valve and Steam, and have begun to lose confidence in Steam. They do not believe that it is reasonable to pay 30% of the platform’s commission to the store.

Epic became the initiator of this battle for platform royalties. Previously, with the popularity of its games such as Fortnite, Epic established its own game platform, Epic Games Store, packaged all its games, and used ultra-low royalties as a means to attract game developers. From previous news, Epic did not intend to treat Steam as a competitor, but more to convey that it wanted to change the 30% cut of computer games (PC) platforms. From the original game developer Deep Silver’s announcement that "Metro 2033" would be exclusive to Epic for a limited time for one year, to the later announcement of a limited time exclusive to the Epic platform by popular game developers, and then to Ubisoft’s removal of "The Division Blockade 2" directly from Steam, game makers and platforms are using actions to demonstrate their views on the cut.

Is 30% reasonable?

---

The 30% platform commission is a traditional system, originally formulated by first-party console manufacturers such as Nintendo, Sony, and Microsoft. The financial resources of Nintendo, Sony, and Microsoft to operate platforms are unmatched by PC platform operations. They have also shown players that operating a PC-side platform, even a 12% commission, is also very profitable. Since the operation of the host platform and the operation of the PC platform are completely different from the difficulty level, it is indeed unreasonable for Steam to operate according to the platform commission of the host manufacturer.

Some netizens broke the relevant commission data of Tencent’s platform: if you just log in to Tencent’s platform, there will be a 30% commission; if you want to promote and use the server, the commission will increase to 50%~ 60%; if it is a mobile game, the commission will be 70%. In addition, the application treasure is 70%; the WeChat mini-game props internal purchase is 40%; the part of the single-day advertising revenue within 100,000 yuan, the developer can get 50% of it; the part of the single-day advertising revenue exceeding 100,000 yuan, the developer can get 30% of it. From this point of view, is the 30% commission not high?

In fact, this is not the case. In China, Tencent owns the vast majority of traffic, and even with a 70% cut, game developers or publishers earn more than many other platforms that take a 10% cut. The main reason why it is unreasonable to say that Steam’s 30% cut is that even in an ideal situation, the income of most profitable game companies is equivalent to the income of the platform, and even the income of the platform is higher than that of the game company. And online game platforms such as Steam,Neither do they have to bear the high costs associated with physical stores and logistics, nor do they have the obligation to help game companies promote their games, which has caused many game makers to be dissatisfied with the 30% cut in recent years.

For an indie game studio, such a high cut would pose a dilemma for the entire team.If the game is handed over to a large company for distribution, and the large company cooperates with Steam, it is equivalent to being drawn twice. And if the independent game team wants to log in to Steam by itself, it will encounter more resistance. On the one hand, Steam will not provide these studios with upfront funding, and it is difficult for an independent development team to complete the game independently without the help of the operating company. On the other hand, the promotion and marketing of the game is very important, and most independent studios do not have the ability to do the follow-up work themselves. In addition, for low-cost indie games, publishing on a high-traffic platform like Steam represents more opportunities, and the advantages outweigh the disadvantages than the high commission.

The fantasy video game website (IGN) has sorted out the sales data of major online sales platforms from dozens of information sources. Surprisingly, the data provided by the vast majority of sources is exactly the same, that is, 30% of the platform. Not only Steam and Apple, but also online sales platforms such as Microsoft, Sony, Google, Nintendo, and offline sales platforms such as Amazon and Walmart draw 30%.It can be seen that a 30% cut is a common practice in the industry and a major environment in the game business community.

---

In the eyes of most game developers, Epic played the role of a revolutionary pioneer, a "leading brother" who explicitly proposed that the 30% cut was unreasonable. However, in the eyes of players, this was not the case. Negative comments on Epic were widely circulated among players. In the eyes of many players, Epic was a speculator, doing things to occupy the market under the name of lowering the platform’s cut.

This phenomenon is very easy to understand, because the level of the platform does not affect the price of the game too much, players can not feel the intuitive benefits, and Epic as a latecomer, the player group is far less than the predecessor Steam, in the platform function and user experience are not as good as Steam, most Steam users are not surprising to Epic.

But there are still reasons to believe that Epic is determined to change the platform’s commission. A 12% commission will undoubtedly attract more and more games to the Epic platform, and Epic expands its player base through a large number of free games and benefits. The substantial benefits that low commissions bring to game developers will gradually emerge, and more outstanding studios in trouble can show their talents on the Epic platform.

In the new game market system, a model full of reform and innovation may be vacated, and Epic has become the person who raises the revolutionary banner, but whether it can become the ultimate winner remains to be seen.

Recently, Liu Yifei’s photo on the inner page of Venezuela’s Ocean Drive magazine was exposed online. In the photo, Liu Yifei is wearing a red dress and has big red lips. She is very beautiful.

The red dress worn by Liu Yifei looked like a fairy, and the mint green fan in her hand also responded to the background behind her. Liu Yifei, who appeared in the shape of red lips, gave people a very amazing feeling, and her eyes revealed a kind of firmness.

Liu Yifei, whose hair is tied into a high ponytail, has another angle of appreciation. This dress, which mixes red and black elements, also reflects another beauty of Liu Yifei: toughness and independence.

The combination of this black cheongsam and black headband makes Liu Yifei look domineering. In the magazine Ocean Drive, Liu Yifei’s looks are full of antique charm, making it easy to think of her film "Mulan".

It is reported that the movie "Mulan" starring Liu Yifei has been confirmed to be released in North America on March 27 this year. This is also Liu Yifei’s most talked-about work since the beginning of the year.

For Liu Yifei to successfully accept the role of Mulan, director Nikki Caro also revealed one of the reasons: during the casting, Liu Yifei overcame the physical discomfort caused by jet lag and carried out a 90-minute physical training. This kind of perseverance is exactly what the character of "Mulan" wants to convey to the audience.

For the sake of the role, Liu Yifei spent six to seven hours training every day for three months. Ninety percent of the action scenes in the film were completed independently by Liu Yifei herself, rather than relying on post-production special effects, such as horseback riding, swordsmanship, martial arts, and so on.

Liu Yifei’s hard work for this role has also rewarded her a lot. She has been on the cover or inside pages of international renowned magazines many times with her role of "Hua Mulan", and has become the focus of global attention. Looking forward to her performance in the movie.

　　　 The European Cup on the other side of the ocean is still in full swing, and full of male hormones makes our fans switch back and forth between staying up late to watch football and going to work. Faced with the serious exodus of fan fans, this week’s "Make an appointment! Big Star" will usher in the most exciting and visually impactful task in history – rugby. President Ruan Jingtian led Wei Chen and Huang Jingyu back to school and played a confrontation with the North Second Foreign Rugby Team that only belongs to the king. Maybe it’s because the temperature is too high, or maybe it’s really getting old. Since the warm-up event, the IQ of the three beautiful men in the House of Everything has been offline. During the official game, Lao Ruan’s legs cramped and fell to the ground. How can the old president stand up and lead the members to protect the dignity of the House of Everything?
　　
　　Warm up before the game "Yushen" brother’s IQ is urgent
　　
　　Although he had only seen rugby before, the house of everything still bravely accepted the challenge of the client. In the face of professional North Second Foreign Football players, it is naturally essential to warm up before the game. During the warm-up mini-game, the "Yuchen" brothers not only couldn’t figure out the rules of the game, but also couldn’t even figure out the even and singular numbers, so they could only involve their teammates to accompany them to push-ups. No wonder the subtitle team couldn’t help but complain: Have you two not studied mathematics?! During the subsequent pitching practice, Huang Jingyu almost hit the camera teacher with a ball, and Wei Chen shouted: "Accurate! Too accurate!" Could this be the rhythm of breaking the can? " Yushen "Brother’s IQ shouldn’t be baked by the sun! President Xiaotian is still counting on taking the two of you to win this game!
　　
　　The battle was intense "old man" Ruan Jingtian fought until his legs cramped
　　
　　Don’t look at the warm-up before the game, everyone is still talking and laughing, but when the game officially starts, the moment the helmet is put on, the members of the House of Everything also become serious, you know that football represents the king’s sport. Sweat to your heart’s content, sparks from body collisions, a game that exudes youth hormones is going on under the scorching sun. Maybe the game is too intense, President Xiaotian’s leg is accidentally injured, and he is lying on the ground in pain. After being massaged and soothed by his teammates, Ruan Jingtian even made a joke about himself: he is old, but his spirit is okay.

In the second quarter, Meituan Preferred transaction volume and revenue continued to grow year-on-year, but the growth rate declined due to the lower-than-expected growth rate of the overall market. Operational efficiency improved significantly compared to the same period last year. Meituan Preferred revenue, recognized on a net basis, declined quarter-on-quarter, mainly due to higher subsidies, which led to lower average price of pieces.

Meituan’s quarterly operating loss widened quarter-on-quarter, mainly due to business expansion, increased subsidies to drive growth, spending on cold chain and logistics to cope with the upcoming hot weather, and seasonal product portfolio changes.

Meituan said that although it faces difficulties in optimizing its business model in the short term, it believes that the online process of groceries will continue, and remains confident in the long-term potential of Meituan Preferred.

The financial report shows that Meituan’s R & D expenditure in the second quarter increased to 5.40 billion yuan year-on-year.

Meituan’s sales and marketing expenses increased from 9 billion yuan in the second quarter of 2022 to 14.60 billion yuan in the same period in 2023. This was mainly due to the recovery in consumption and changes in the business environment, resulting in higher transaction user incentive, promotion and advertising expenses, and higher employee benefits expenses.

The company’s general and administrative expenses decreased from $2.50 billion in the second quarter of 2022 to $2.10 billion in the same period in 2023, mainly due to lower employee benefit expenses and improved operating leverage.

Meituan CFO Chen Shaohui said that in the first half of this year, the local life sector benefited from the vigorous growth momentum of commodity retail and service retail, meeting more new demand and creating more new supply. In the future, Meituan will further promote the digital upgrade of the commodity retail and service retail industry.

　 　 The most classic Chinese kung fu film is about to be remade again. The reporter learned from the filmmaker yesterday that "Huang Feihong’s Hero has a Dream", which is jointly invested by Anle Film Co., Ltd., Wanyuan Gravity Film Co., Ltd., Shengfei International Digital Special Effects Production Co., Ltd. and other parties 80 million RMB, will start filming in Shanghai and Wuzhen. The film recruits the strongest soldiers in the Chinese film industry, and in line with the tenet of "challenging the classics and replicating the classics", creates a new version of the classic kung fu film and pushes it to the world. At the same time as announcing the shooting plan, the filmmaker also announced the first batch of main creators yesterday, and all stars such as Hong Jinbao, Jing Boran, Wang Zulan, Zhang Jin and Feng Jiayi joined. Jiang Zhiqiang, Liu Erdong and Ho Yunming are the film producers, the director is Chow Hsien Yang, and the screenwriter is Du Zhilang, a talented Hong Kong woman. At the same time, Yuen Kui is the action director, and Liu Fang is the martial arts director. The most talked-about role of Huang Feihong remains mysterious.

Challenge the classics, copy the classics

　 　 "Wong Fei Hung’s Heroes Have Dreams" was produced by former gold producer Jiang Zhiqiang. Directed by Hong Kong director Chow Hsien Yang, the former director of "The Great Hunt" and the latter is the screenwriter of He.

　 　 After 20 years of filming Tsui Hark’s version of "Wong Fei Hung", it is no small ambition to challenge the kung fu classics again. In this regard, Mr. Jiang Zhiqiang said that this move is actually to make some efforts for the kung fu genre. "I have sold a lot of films abroad, and I deeply feel that only kung fu films can travel all over the world in Chinese movies. But after so many years, in the Chinese film world, there are fewer and fewer creators who can really make kung fu films. If you don’t make a classic, I am afraid that it will become a swan song. And’Wong Fei Hung ‘is the pinnacle of kung fu movies. We don’t want to challenge the classics, we only want to be able to copy the classics and leave the world a good
"No one has brought Wong Fei Hung to the big screen for more than 20 years," the director, Chow Hsien Yang, emphasized. "This is the longest’Wong Fei Hung vacuum ‘in Chinese film history since the 1950s. So this year is the best time to reshape the’new Wong Fei Hung series’. After a long preparation, I am full of confidence in it."

Real boxing, real kung fu

　 　 Continuing the previous Xu Ke version of the "Huang Feihong" series, this time "Huang Feihong" is subtitled "Heroes Have Dreams". It tells the story of the late Qing Dynasty, by the Pearl River wharf in Guangzhou, the Black Tiger Gang carried out despicable human trafficking activities. Huang Feihong was very anxious when he saw it. He and his friends cleverly set a trap, saved the poor, created a new world with their hands, and began Huang Feihong’s legendary life…

　 　 "Wong Fei Hung is an example of an Oriental superhero. This time’Wong Fei Hung ‘wants to talk about dreams, the spirit of’knowing that you can’t do it and doing it’. In times of despair, with personal will, self-improvement belief, and strong physique, you can achieve the impossible. I firmly believe that perseverance is the final victory. Start with your own beliefs and expand them to infect others and unite everyone. This is: Wong Fei Hung." Zhou Xianyang introduced that the film will retain the essence of many "Wong Fei Hung" movies. "The biggest feature is that all our actors must really fight real punches and have real kung fu. Therefore, every actor who enters the group to act will basically come to practice in advance. So far, everyone’s progress has been rapid, which makes me very confident in the movie."
It is reported that in order to show the real boxing and real kung fu, the film also specially invited the international action director Yuan Kui as the action director to train the actors in martial arts moves. At the same time, the famous Nanquan master was also invited to teach boxing for several main creators. "I know that filming’Wong Fei Hung ‘is very stressful, but our determination is greater, and perseverance will be the greatest," the director said.

Hong Jinbao led Jing Boran to join

　 　 Since the real boxing is real kung fu, the cast of "Wong Fei Hung’s Hero has a Dream" is also highly anticipated. Hong Kong movie veteran actor Hong Jinbao, film and television song king Jing Boran, kung fu star Zhang Jin, as well as popular superstar Wang Zulan and powerful actor Feng Jiayi are the first to be announced.

　 　 Among them, Hong Jinbao is the big brother of kung fu movies, leading "Qi Xiaofu" including Jackie Chan to pioneer a new genre of Chinese movies. Joining "Huang Feihong" this time is also intended to revive kung fu movies and create a new world of movies in this genre. Jing Boran, the little king of the mainland, has starred in just a few years, and Teng Huatao’s new play with him as the male lead is about to be released. It has been regarded as one of the most promising male actors in the industry in the future.

　 　 The actor, Zhang Jin, is a national champion of martial arts in Chen-style tai chi and tai chi swords, as well as a champion of spear and swordsmanship. He has appeared in several kung fu movies, including the impressive Ma San in Wong Kar-wai. Wang Zulan played a character in "Wong Fei Hung," challenging his comedic character. As for Feng Jiayi, who has performed splendidly in TV series such as "Double-sided Tape," "Wo Ju Ju" and "Naked Marriage Times," this time he will play the boss of the Black Tiger Gang in "Wong Fei Hung," which is his period costume debut.

　 　 The director, Chow Hsien Yang, said that he had spent months watching the actors’ works and trying on makeup. "This story needs a big brother like Samuel Hung to be in charge, and we also hope that a group of young people such as Jing Boran will bring more youthful elements to the film." He also revealed that Hong Jinbao will play a domineering villain in the film this time. However, the director said that there is still suspense about the choice of the core character Huang Feihong.

    On March 12th, China Star Double Flagship staged a wonderful and exciting extreme challenge in Sanya. During the activity, China Xingshuang Flagship carried out three extreme challenges, namely, soaring in corners, seesaw at high altitude and steel Weiya, which showed the performance, safety and quality of Geely CMA architecture system.

    At the event site, Fan Junyi, general manager of Geely Automobile Sales Company, announced that Chiu Man-Cheuk had become the "China Star Ambassador", and officially announced that the market guidance price of Xingyue L 8AT two-wheel drive flagship model was 168,200 yuan, providing users with another brand-new choice.

    Thanks to Geely 4.0 standard and CMA architecture globalization technology, China Xingshuang flagship has inherited the excellent quality of leading safety performance, electronic and electrical architecture and high-performance surging power, and has excellent strength in power, chassis and safety.

    In the "fast" move-the curve hurricane challenge, the newly launched Xingyue L 8AT two-wheel drive flagship and speedboat staged a visual feast of extreme hurricane on land and sea. Xingyue L started fast, the acceleration in the latter part continued to be strong, and the 100-kilometer corner accelerated by 7.9s, winning the first move.

    Xingyue L 8AT two-wheel drive flagship model is fast, mainly due to its 2.0TD high-power engine+Aisin 8AT new transmission. This Drive-E 2.0TD luxury engine has a maximum power of 175kW and a peak torque of 350N·m, and won the "Top Ten Ward Engines" for three consecutive years. The engine adopts high-efficiency supercharging technology, and the maximum speed of turbocharger /min 200,000 rpm, which makes the low-speed response faster. With the intervention of 1000 rpm turbine, the output torque is 160N·m, and the maximum output torque is 350N·m at 1800rpm.

    In terms of transmission, the flagship model of Xingyue L 8AT two-wheel drive is matched with the 8AT gearbox of Aisin Seiki, making it the only two-wheel drive model equipped with 8AT in Xingyue L. Aisin 8AT reduces the friction coefficient of the tooth surface through a new gear processing method, thus reducing the energy loss when the gear is engaged. Aisin 8at has all-round advantages such as efficient power transmission, smooth transmission, high reliability, low noise and small vibration, and perfectly transmits the power to the wheels. With CMA wire-controlled chassis operating stably, Xingyue L 8AT two-wheel drive flagship curve accelerates 7.9s per 100km, and straightly accelerates 7.5s. The fuel consumption is 6.9L under NEDC working condition.

    In the "tough" trick-high-altitude seesaw challenge, Xingyue L climbed a 37-degree high slope, reached the top of the 10-meter-high slope, stopped at the center of the seesaw accurately, and then drove down smoothly from the other end of the seesaw, showing excellent four-wheel drive climbing ability, precise power control and braking performance.

    According to the person in charge of CMA vehicle R&D of Geely Brand Research Institute, Xingyue L adopts CMA world-class architecture, and combines the world-leading "chassis by wire" with innovative design to realize centralized calculation of vehicle-related data such as braking system, transmission system, steering system, power system and induction system of chassis, with joint debugging, joint control, more positive feedback response and more direct driving intention. Secondly, whether the braking is more linear and whether the continuous braking is more stable. The good braking performance of Xingyue L benefits from the adoption of Italy ITT copper-free brake pads, oversize vacuum booster, oversize front ventilation disc and rear solid disc, and exclusive customized Goodyear Eagle F1 high-performance tires, which have strong grip and stable handling.

    Equipped with Borgwarner’s sixth-generation four-wheel drive system, Xingyue L four-wheel drive version realizes 50:50 front and rear axle torque distribution, which brings stronger off-road performance and passing performance. Even on wet and rugged roads, it can quickly adjust the power distribution of four wheels, and the maximum climbing angle can reach 37. Compared with the fifth generation, the performance of the sixth generation four-wheel drive has been improved in an all-round way, with the maximum bearing torque increased by 19%, the response speed increased by 16.7%, the torque accuracy increased by 33.3%, and the weight reduced by 15.8%, achieving stronger power, faster response, more accuracy and lighter weight, which can be handled calmly regardless of climbing mountains and stepping on snow.

    In the "steady" trick-steel Weiya challenge, the gap data of three points of Xingrui car door at rest are measured at first, which are 3.4mm, 3.5mm and 3.4mm respectively. During the challenge, the B-pillar on one side of Xingrui is connected with the crane, and another Xingrui is suspended through the suspension of the front and rear cars. The B-pillar connected with the crane bears 3T load, and finally the vehicle is suspended for swing test. After the challenge, the data of the three points of Xingrui are 3.4mm, 3.6mm and 3.5 mm. After comparison, there is only a slight change of 0.1mm before and after suspension, and the challenge is successful.

    Geely CMA architecture, with forward-looking technology and R&D and manufacturing standards, has five qualities of safety, health, intelligence, performance and energy saving, and is the core of creating "value competition" in the era of comprehensive architecture of Geely 4.0. With the three core values of CMA architecture, China Xingshuang flagship has been selling well since its listing, and the cumulative sales volume has exceeded 580,000. In the future, Geely brand will continue to promote product-level innovation with CMA architecture, and drive the overall breakthrough of the brand with flagship products.

　　Yesterday morning, Beijing time, just a few minutes before the China women’s volleyball team won the championship in Rio, good news came back from Kansas City, Missouri, USA. Hao Jingfang, a female writer, won the Best Short Story Award in the 74th Hugo Award for her "Folding Beijing". Hugo Award is known as the Nobel Prize in Literature of science fiction, which is the second China writer to win the award after Liu Cixin’s Three-body. In her speech, she said, "I don’t want my novel to come true. I sincerely hope that the future will be brighter."

　　acceptance speech

　　I hope the future is brighter.

　　Last year, Liu Cixin won the Hugo Award with the English version of Three-body, which promoted the development of the whole science fiction industry in China. This year, Hao Jingfang continued to heat up from being shortlisted to winning the award again. Coincidentally, the English translators of their winning works are both Chinese science fiction writers Liu Yukun. At the end of April this year, Hao Jingfang won the attention of domestic publishers after being shortlisted for the Hugo Award. First, he published the autobiographical novel Born in 1984, and then he concentrated on publishing Lonely Deep, Far Away and Wandering Sky.

　　In the face of outside enthusiasm, Hao Jingfang himself is relatively calm. In an interview with the Beijing Times, she said that she didn’t want to create a cage for herself. "Too much attention may not be a good thing, which will affect the pace of life." Before the winners were announced yesterday, she was in a normal and tangled state. On the one hand, she felt that "winning the prize was not completely unexpected", on the other hand, she was thinking about going to the loser’s party.

　　When Hao Jingfang delivered her acceptance speech, she expressed her thoughts on the plot setting in the novel. She said, "Science fiction writers like to consider all possibilities, good or bad, lucky or unlucky. They will discuss what strategies to adopt to deal with aliens and so on. Basically, they live in countless parallel universes. In the novel Beijing Folding, I put forward a possibility of the future and faced various problems. At the same time, I also put forward a solution, which is obviously not the best result, but it is not the worst. I personally don’t want my novel to come true. I sincerely hope that the future will be brighter. "

　　Inner circle reaction

　　Liu Cixin: I find it hard to believe that she wrote it.

　　China’s science fiction literature circle is not big, and Liu Cixin has always appreciated Hao Jingfang. He once compared Hao Jingfang’s style with the works of science fiction master Ray Bradbury, saying that "she sprinkled a poetic sunshine on our common science fiction themes". At the Shanghai Book Fair yesterday, Liu Cixin launched and signed the English version of the trilogy "Three-body", and nearly a thousand copies were signed on the spot, which shows the popularity.

　　After learning that Hao Jingfang won the prize, he first expressed his congratulations. When talking about the work "Beijing Folding", Liu Cixin said that it was well written: "This work is very different from her previous works. If you just show me this work, I can hardly believe that it was written by her. Jing Fang’s previous works are very beautiful and elegant, and because she has a doctorate in economics, her settings are all based on the economy. " Hao Jingfang once said that her novel wanted to write the "warmth" of this cruel setting.

　　During the signing process, a reader asked Liu Cixin if he would write short stories in the near future. Liu Cixin said: "At the beginning, I wrote a lot of short stories, mainly because it was difficult to send long stories at that time." In just two years, Chinese people’s enthusiasm for science fiction has rapidly warmed up. Yao Haijun, editor-in-chief of Science Fiction World magazine, believes that Liu Cixin’s award has ignited Chinese people’s enthusiasm for science fiction, while Hao Jingfang’s award will help readers adjust their mentality to normal.

　　Who’s Hao Jingfang?

　　Hao Jingfang was born in Tianjin in 1984. At the age of 9, he read "100,000 Why" and decided to become a scientist. In 2002, he won the first prize in the 4th New Concept Composition Competition. When she was shortlisted for the Hugo Award, a Zhihu netizen said, "This girl was a scholar in the class next door that year. The ranking she took in the new concept composition seemed to be enough for the Chinese Department of Peking University to be exempted from the exam, and then she was admitted to the Physics Department of Tsinghua. At that time, I also thought that this kind of learning god appeared in the list of scientific research cows a few years later. As a result, I saw that she was nominated for the Hugo Award. It was really IQ crushing all the time. "

　　In 2006, Hao Jingfang graduated from the Department of Physics in Tsinghua University and entered the Tsinghua University Astrophysics Center. In this year, he officially began to write science fiction. So far, he has published the novel Wandering in the Sky, the collection of short stories, such as Star Traveler, Far Away and Lonely Deep. Later, Hao Jingfang transferred to Tsinghua University School of Economics and Management to pursue a doctorate, and in 2013, he began to work for China Development Research Foundation.

　　In the novel "Beijing Folding", she fictionalized Beijing as a triple space, and people in each space were in different situations. The protagonist was a garbage man, Lao Dao, who ventured to deliver letters in other spaces in order to pay the kindergarten tuition for the picked-up children. At present, the novel is included in the new book "Lonely Deep". In addition, the reporter learned from Palm Reading Technology that the electronic version of "Lonely Deep" has downloaded more than 300,000 copies in just two months since it was launched on June 17.

　　Jinghua Times reporter Tian Chao

CCTV News:Wulanchabu, which has the reputation of "Potato Capital of China", is located in the yinshan mountains, with large temperature difference between day and night and abundant sunshine. It is a golden potato planting belt, and its output accounts for nearly half of that of Inner Mongolia Autonomous Region. In these two days, Chayou Houqi in Wulanchabu ushered in a bumper potato harvest.

Reporter Yuan Yi:Do you think the potatoes in my hand are different from what I usually see? Its skin is red, and its name is "Houqihong". There is Ulan Hada volcano in Chayouhouqi where we are located, and these potatoes grow at the foot of the volcano. These potatoes can be said to be "drinking" volcanic magma mineral water and "enjoying" the sufficient sunshine at 41 north latitude.

Reporter Yuan Yi:Potatoes taste really good. Now the potatoes here have entered the harvest period, and harvesting potatoes is also very knowledgeable. Potato skins are thin and easy to be scratched, so they are all sorted manually. The colors of these bags are different. Look, this big sister’s bag is white, and the potatoes in it are quite big.

Farmers:Generally, it is more than three or two.

Reporter Yuan Yi:Smaller potatoes like this will be put in yellow bags.

Reporter Yuan Yi:How much can I charge a day?

Farmers:More than 200 bags.

Reporter Yuan Yi:Collecting potatoes in this field depends on unity and cooperation, and the separation of all the way is another harvest scene. The potatoes planted in this nearly 700-mu field are mainly used for starch processing. This working combine harvester works from turning the soil, shaking the soil and bagging in one go. From a distance, this big guy seems a bit heavy, but from a shooting perspective on the machine, we can see that the potatoes are spinning rapidly on the conveyor belt, and its efficiency can reach 5 mu per hour.

Although the seed potato is small, it undertakes the heaviest task, and one can sell for 3 to 50 cents, because it determines the yield of potatoes.

In addition to deep cultivation of potatoes, extending the industrial chain can double the price of potatoes. Here are all products processed with potatoes, including potato chips and environmentally-friendly disposable lunch boxes. At present, the total value of the whole potato industry chain in Inner Mongolia is 13 billion yuan, so it can be said that "small potatoes" have become the "Jin Doudou" for farmers to increase their income and get rich.
