This generation of young people have long been unable to integrate into the social process of "eating and drinking mahjong KTV" of their parents, but in reality, they are limited by time and space and cannot expand their social circle. They establish contact with strangers outside the life and work circle through online games and thus have emotional connections. Games have become the social currency of a new generation of young people.

Mobile games and e-sports have long been popular in the streets. At the moment of winning the championship, the popularity in bilibili live broadcast room has reached more than 400 million, and the popularity of Tiger Tooth live broadcast has reached more than 300 million. Judging from the popularity of its various online platforms, e-sports live broadcast has long been a national entertainment activity.

The market scale of the game has derived the social demand of the game, and the upcoming TT focuses on the social voice of the game, thus harvesting 100 million users. However, under the precedent of many social platforms that died of social atmosphere, 90% of users are TT voices after 95 s and 00 s, but people have to worry, can game-based socialization go on healthily?

From game voice to social tools

At first, TT voice was just a voice tool.

In 2012, the mobile game industry in China began to enter an explosive period, and a large number of game practitioners rushed into the game content production industry in an attempt to create an explosive game. However, at that time, most games were still in the initial stage, and there was no perfect voice communication system, but the need for players to communicate in time was very urgent.

Based on this, Fun Pill Network chose to start from the game voice tool. In 2014, TT voice became an instant hit. In the first year, the number of registered users exceeded 3 million, and the number of online users exceeded 60,000. In one year, the running water exceeded 100 million yuan.

However, it is difficult for tool apps to achieve considerable revenue. Moreover, after 2016, more and more games that need to be "blacked out" have added built-in instant voice systems, and the core business of TT voice has been impacted, not only because the ceiling is too low, but also because the tools themselves have become chicken ribs.

"Blackout" in the game itself is a social way, therefore, social transformation has become the easiest path for TT voice to cut in. In 2018, TT voice gradually added live voice, expanded chat, pia drama, dynamics and other kinetic energy, which was deeply tied with explosive mobile games such as the glory of the king and Peace Elite, enabling gamers to directly perform voice hacking, teaming up, scoring and other operations within TT voice, broadening the use scenarios of TT voice, and the average online market for daily users exceeded two hours.

In the field of game socialization, TT voice can be regarded as a deep-rooted player. For example, in finding a playmate, the glory of the king’s matching mechanism does not allow too much difference between segments. Many players find it difficult to match the right teammates and opponents with the same segment because the segment is too high or too low, but TT Voice can find the right playmate with the same segment based on the game and gender, so as to recognize gamers who have the same topic cognition.

In fact, not only mobile games like the glory of the king Peace Elite have voice social needs, but other games also have voice social needs, but many minority games have no funds and strength to add voice built-in and social channels. The "quick matching" of the "black channel" on TT voice homepage not only covers high-heat mobile games such as the glory of the player, the peaceful elite, the call of duty, the fifth personality, but also covers leisure and educational games such as light encounter, gobang, you draw and guess, which makes TT voice not a vassal of a certain game, but the best playmate of the game, and can inject fresh blood into the platform while stabilizing old users.

In addition, TT voice is not only satisfied with finding suitable game playmates for players, but also based on user interest tags and other information, using system algorithms to gather people with similar interests in the virtual room voice room by distributing playmates, finding radar and other functions, and sharing audio, video, pictures and other contents in real time to achieve the purpose of making friends. In addition to "playing in black", TT voice also opened content sections such as finding playmates and entertainment.

Judging from these functions, TT voice is not only a tool, but also a social ecology based on games, which meets all the online entertainment and leisure needs of this generation of young people.

Therefore, TT voice also has a living space outside the game content. According to publicly disclosed data, the unique TT voice has accumulated more than 100 million users by 2020, an increase of more than 80% from the previous month. In addition, the platform MAU reached 20 million, of which the post-95 s, that is, Z generation users accounted for as high as 90%.

During the first half of 2021, users spend about 158 minutes in TT voice chat rooms every day, and users initiate more than 850,000 voice chat rooms every day, an increase of 45.6% compared with the same period in 2020.

Sullivan pointed out in the report that TT voice has become the largest mobile voice social platform and the largest player-centered mobile social platform in China according to monthly users and income data.

The ceiling is too low and it is too difficult to grow.

According to the data of China Game Industry Report 2020 released by China Game Industry Research Institute, the number of game users in China will reach 665 million in 2020, with a year-on-year increase of 3.7%. In other words, there is one TT voice user in every six e-sports players.

However, it is worth noting that TT voice is actually known outside the deep e-sports players. Because almost every popular game has its own social function, players can achieve basic needs such as communication and team formation in the game. With the improvement of the voice communication system of the game itself, the chances of players opening the voice-assisted APP are bound to gradually decrease.

Therefore, it is not an exaggeration to say that TT voice survives in a crack, and this crack makes it difficult for TT voice to make a breakthrough in market scale.

In addition, there are too many voice social software, and the substitutability of TT voice is very high, not to mention that WeChat QQ can open black communication games in groups, and there are also black-opening software such as YY voice, KK voice and hello voice in the market to compete with it. In contrast, the competitive advantage of TT voice is not clear.

According to the prospectus, in the first half of 2021, the monthly activity of TT voice reached 16.2 million. Compared with the social products such as Gathering Times and Momo, the number of monthly users of less than 20 million is not large enough.

The ceiling is too low, the loyalty is not enough, and the user payment rate is also very low. According to the data in the prospectus, the monthly living payment rates from 2018 to 2020 were 7.3%, 7.1% and 5.3% respectively, and even fell to 5.1% in the first half of 2021, the lowest level in history.

In addition, the target users of TT voice are the post-95 s and post-00 s under the age of 24, but this young group has limited spending power and it is difficult to promote more consumption.

Moreover, the acquisition cost of TT voice is not low. According to the prospectus, in 2020 and the first half of 2021, the network and marketing expenses of Fun Pill Network increased by 123.06% and 120.88% year-on-year, both higher than the revenue growth in the same period and higher than the growth rate of paying users.

In addition, as an auxiliary tool APP, TT voice also needs to solve the problem of user retention. At the beginning, TT voice can be downloaded because of the formation of playmates, but after a short period of acquaintance and pairing, playmates who form fixed friends often develop into daily communication software such as WeChat /QQ for voice, dialogue, making friends, opening black and other activities.

As far as social tools are concerned, most of WeChat and QQ are bound with offline real social information, so the probability of users uninstalling software and accounts is very low, but only a small social APP with Internet strangers’ "friends", which leads to a higher probability of uninstalling software and accounts because of the low maintenance cost, making it difficult for users to really keep them.

In this way, TT voice has become a diversion middleman of WeChat QQ, and it is difficult for users to really stay. In fact, this problem is not only the embarrassment of TT voice, but also the embarrassment that all niche social tools except WeChat QQ are difficult to solve.

Risk involved in gray areas is high.

Almost all Internet companies want to socialize, and Ma Yun’s Alipay is no exception. However, social functions are easy to build in, but it is extremely difficult to make social apps.

In particular, it is indeed the common demand of a new generation of young people to make friends through games, but social interaction based on games can be an interest, but it is also easier to deteriorate.

With the development of Qinglang Action, many accompanying software such as "Bixin", "Little Deer Accompanied Play" and "hello Voice" have been taken off the shelves indefinitely because of illegal activities such as fraud and pornography, and social software accompanying games has become a high-risk zone for juvenile supervision.

Although TT voice has not been removed, it does not mean that it does not have this problem. On the home page of TT voice, the online number of blind date rooms has exceeded that of black-out, party, listening to songs and other rooms.

The content of "edge ball" can be said to be the user’s low quality, but TT voice belongs to the "ignition" in this kind of edge ball socialization, and the official attitude may even imply encouragement. Many users reported that TT voice received an "immediate private chat" automatically matched by the system after the initial download and registration, and the dynamic recommendations were all kinds of speeches and private messages.

Some media reports have pointed out that TT voice has voice rooms named after minors, and some voice rooms have voice contents such as suspected obscenity and abuse, and the report pointed out that the platform did not block these live broadcast rooms during the investigation.

On the black cat complaint platform, the number of complaints about TT voice is as high as 2,705, which is more than two old-fashioned voice software such as Momo YY live broadcast. The complaints include problems such as fraud, inducing minors to pay, and swearing.

There are also public reports this year. A 9-year-old girl from Guangzhou once got to know the suspect Lu Mou after downloading TT voice chat dating platform. Lu Mou gave her a red envelope in the name of giving gifts. Due to lack of judgment, she was cheated for 12,781 yuan.

TT voice expanding social interest content outside the game may encourage dangerous discussions. In the "expanding column" section of TT voice, there are a large number of underage users, and most of them are involved in puppy love, and the situation is extremely serious. The section of "Minors posting to find boyfriends in public" even has a very obvious recommended position in the APP, and even pornographic content shows obvious recommended positions, as well as obscure yellow-related drainage stickers.

Although social software can’t supervise all users’ languages, the target users of TT voice are mainly minors and young students under the age of 25. Are you sure this high-risk social interaction is not playing with fire?

At present, TT voice has no underage review mechanism. After downloading, registration can be completed only by receiving a four-digit verification code from the mobile phone, which means that minors can complete registration without even unlocking their parents’ mobile phones, and can be used to contact all users without their real names or any third-party information.

Judging from its official attitude, although the youth model has also been established, most of the contents under the model are subject education courses. Obviously, there is no active and healthy planning and guidance for the healthy socialization of minors’ interests.

Although the state has issued policies to restrict the related behaviors of minors’ games, the surrounding industries of games also need strict supervision. Whether it is live broadcast or accompanying play, enterprises should actively fulfill their responsibilities to protect young people, and should not lower the lower limit in pursuit of market scale.

　　Beijing, Dec. 14 (Leng Yuyang) According to the news from the Examination Center of the Ministry of Education, the CET-4 and CET-6 will be held today in the second half of 2019, and candidates can check their scores in February next year. In recent years, there has been a constant debate in public opinion about the reform of CET-4 and CET-6, and even the debate about whether to keep or abolish it. In the future, how to evaluate the English proficiency level is worthy of attention.

　　College English Test Band 4 and Band 6 starts today.

　　According to the news from the Examination Center of the Ministry of Education, the CET will be held on December 14th in the second half of 2019. Among them, 9: 00 am & mdash; Take CET-4 at 11:20, and at 15:00— At 17:25, the CET-6 will be conducted.

　　On the eve of the exam, many provincial education examination institutes issued a reminder that candidates must enter the examination room with the admission ticket, student ID card and valid ID card on the day of the exam (starting at 8:45 am and starting at 2:45 pm), and the "three certificates" are indispensable. Admission is forbidden after 15 minutes.

　　During the examination, candidates are only allowed to bring necessary examination stationery into the examination room, and are not allowed to bring books, materials, bags and other items. It is strictly forbidden to bring electronic equipment with the function of sending or receiving information. Once found, it will be dealt with in violation of regulations, and the results will be invalid.

　　According to the pre-test reminders issued by various places, before the exam, there are often some lawless elements and intermediaries in the society who use the Internet and other tools to publish harmful information such as "helping the exam", "providing real questions" and "answers" and peddling cheating tools, and claim to "package" to defraud candidates of money. Please don’t believe in false propaganda, so as not to be deceived.

　　Under the current examination system, the CET written test is held twice a year in June and December of each year. In June, all subjects in English and non-English are taken, and only English subjects are taken in December. CET oral test is held twice a year, in May and November each year. Since December 2016, candidates who apply for the written test in the same year are eligible to apply for the same level of oral test.

　　Candidates can check their scores through the official website of CET-4 and CET-6 in February next year.

　　Debate on the reform of CET-4 and CET-6

　　The National College English Test Band 4 and Band 6 is a large-scale standardized test sponsored by the Ministry of Education and presided over and implemented by the Examination Center of the Ministry of Education. Since its implementation in 1987, CET-4 and CET-6 have gone through more than 30 years, accompanying the youth of generations of students.

　　In order to constantly meet the needs of students learning English, CET-4 and CET-6 have been on the road of reform. The reporter found that in recent ten years, various reform schemes, such as taking multiple questions and volumes, canceling cloze, increasing Chinese-English translation scores, and changing fast reading comprehension into long reading comprehension, have been implemented in CET-4 and CET-6.

　　On October 23 this year, the plenary session of the National College English Test Committee for Band 4 and Band 6 in the second half of 2019 held in Shanghai said that the use of artificial intelligence technology has obvious effects on improving the quality of marking papers, and it is suggested to further strengthen research and gradually promote it. Moreover, the CET test system still needs to be further improved, and it is suggested that CET oral test should be included as a compulsory subject as soon as possible, which is beneficial to college English teaching.

　　In fact, in recent years, some experts and scholars have called for "canceling the CET-4 and CET-6 examination" and "turning to the socialization level examination".

　　In January this year, Cai Jigang, a professor at Fudan University and the president of China Academic English Teaching Research Association, published an article in the media entitled "CET-4 and CET-6 can be turned to socialization level test". According to the article, CET-4 and CET-6 have even seriously affected the higher requirements of college English, and standardized tests have also affected or even seriously affected the development of college students’ critical thinking ability.

　　In Cai Jigang’s view, higher education is a systematic process, and each major or course can’t be selfish. College English can only be a service course. Different disciplines and majors have different needs for English, and the English proficiency test should not be "one size fits all". CET-4 and CET-6 should be turned to socialized proficiency test as soon as possible.

　　At the same time, however, there are voices that the CET-4 and CET-6 can’t fully reflect the level of the subjects, but its existence value should not be denied.

　　According to a commentary published by China Youth Daily at the end of 2017, CET-4 and CET-6 cover listening, reading, translation and writing. At the same time, an oral test is set, which covers listening, speaking, reading and writing, and the test items are relatively flexible. Compared with IELTS or TOEFL, which cost thousands of registration fees, CET-4 and CET-6, which can be applied for only tens of yuan, is still the "gold standard" for evaluating the English level of most China students.

　　Chu Zhaohui, a researcher at China Academy of Educational Sciences, told Zhongxin.com that although CET-4 and CET-6 have played a lot of positive roles in history, the shortcomings of their unscientific inspection standards and insufficient pertinence have hindered students’ English learning. Relevant departments may wish to listen to the suggestions of academic circles and replace them or carry out more drastic reforms.

　　When will the future English test come?

　　The reporter noted that as early as 2014, the State Council issued the "Implementation Opinions on Deepening the Reform of Examination Enrollment System", proposing to strengthen the construction of foreign language proficiency assessment system, which is the first time at the national level to put forward clear requirements for the comprehensive reform of foreign language examinations.

　　In February 2018, the Ministry of Education and state language commission officially released the China English Proficiency Scale, which is the first English proficiency assessment standard for English learners in China. At that time, when answering a reporter’s question, the person in charge of the examination center of the Ministry of Education said that on the basis of the scale, the examination center of the Ministry of Education was developing the English proficiency test.

　　In December this year, Yu Han, deputy director of the Examination Center of the Ministry of Education, revealed at the 2019 TOEFL annual meeting that the overall design of the China English Proficiency Test has been completed at this stage. "The focus of the previous research is to develop exams corresponding to the corresponding levels of higher education. At present, the design and demonstration of the examination syllabus have been completed, and the test work has been carried out in some colleges and universities. "

　　In view of the speculation that China English Proficiency Test will replace CET-4 and CET-6, on December 11th, the relevant person in charge of the Examination Center of the Ministry of Education responded to the media reporter and said: How to integrate the new system with the existing examination items and do a good job in inheritance and development, we are studying and widely listening to opinions.

　　In addition, it is worth noting that another national-level general English test — — The National English Test has been suspended in Sichuan, Liaoning, Jiangxi and Henan provinces.

　　The comprehensive reform of foreign language examination is progressing continuously, but the final direction of CET-4 and CET-6 is still inconclusive.

　　In April, the promotion policies of new energy vehicles were frequent in various places. Xi ‘an announced that it would implement the charging service fee standard for new energy vehicles from April 10, and encouraged charging facility operators to implement preferential policies for users. Shanxi, Shanghai, Hangzhou and other places also successively introduced corresponding support policies. A few days ago, the third batch of new energy vehicle catalogues was also announced, with a total of 309 models on the list. Since the introduction of the new new new energy vehicle catalogue in January 2016, more than 1,000 models have entered the new catalogue.

　　While various automobile manufacturers vigorously promote the research, development and promotion of new energy automobile products, social capital has also flooded into this field on a large scale, which has spawned various modes such as Internet car-making and third-party services. At the same time, new energy vehicles have attracted more and more attention from the capital market.

　　Trend capital pays attention to new energy vehicles

　　On April 1st, the pure electric vehicle Tesla MODEL 3 started booking around the world. As of April 3rd, Model3 had received nearly 300,000 orders with a total value of more than 10 billion US dollars, and the market booking volume far exceeded expectations.

　　Tesla effect drives the A-share new energy vehicle sector to rise. On the morning of April 5, the market opened, and the words Dafu Technology, Hongte Precision and Hongfa Shares were daily limit. Subsequently, Guangdong Hongtu, Changxin Technology, and Xinzhi Motor had daily limit. As of the close of the day, more than 20 stocks in this sector had daily limit. At the close of April 6, Nord’s shares rose daily, and the lithium battery sectors such as Polyfluoride, Ganfeng Lithium Industry and Tianqi Lithium Industry also rose by more than 4%.

　　Not only has the stock price soared, but new energy vehicles have also become hot in the capital circle. Shenzhen O-film Tech Co.,lt, a listed company engaged in auto parts business, recently announced that it plans to subscribe for the registered capital of 80 million yuan (80 million shares) of Beijing New Energy Automobile Co., Ltd., a subsidiary of Beijing Automobile Group, at the price of 204 million yuan and 2.56 yuan per share.

　　In the past month, many listed companies such as Bohai Piston and Guoxuan Hi-Tech have become new shareholders of BAIC New Energy. According to the announcements of the subscribers, the target of this round of capital increase launched by BAIC New Energy in March this year is 1.2 billion yuan. After the subscription is completed, the registered capital of BAIC New Energy will increase from the existing 2 billion yuan to no more than 3.2 billion yuan.

　　BYD Auto started construction of a new energy vehicle production base in Taiyuan, Shanxi at the end of March, with a total investment of 4 billion yuan, and an annual output of 5,000 pure electric buses, 5,000 pure electric buses and 2,000 industrial and mining vehicles.

　　At the same time, many social capitals have entered the service fields of new energy vehicles such as charging piles and time-sharing leasing. The reporter learned that Yikai Car Rental is an enterprise engaged in the third-party service of new energy vehicles. By establishing a large number of new energy vehicle rental points including parking spaces and charging piles, it serves consumers in a time-sharing mode. At present, this model has been operated in Wuhu, Anhui Province for more than two years, and has gained good experience and matured.

　　Promotion of the status quo is the primary issue.

　　Since the private market of new energy vehicles was opened in 2014, new energy vehicles have been growing at multiple times in the past two years. According to the statistics of China Automobile Industry Association, the production and sales of new energy vehicles increased by 1.7 times in the first two months of this year compared with the same period of last year, and the production and sales of pure electric vehicles increased by nearly 3 times respectively. At the same time, however, the promotion of new energy vehicles is still the most important issue at present, affected by factors such as cruising range, cost and price, and charging facilities. How to promote the development of new energy vehicles through the innovation of policies, modes, technologies and services has become a topic of common concern.

　　Both auto companies and social operators have a clear understanding of this. Zhang Yong, deputy general manager of Beijing New Energy Automobile Co., Ltd. and general manager of the marketing company, said that Beijing New Energy Automobile has developed from a single model to multiple series, and established the service brand of "Smart and Smart Housekeeper", and opened up the demand of market users and opened up markets such as Beijing, Shanghai, Shenzhen, Guangzhou, Qingdao and Sanya.

　　"The promotion of new energy vehicles in first-tier cities has policy advantages such as restrictions on purchases and restrictions. However, it is impossible to improve air quality only by promoting new energy vehicles in first-tier cities. How to promote new energy vehicles in the vast second-and third-tier small and medium-sized cities has become an important issue. The model of easy car rental is to solve this problem. " Yan Daoyuan, chairman of Yikai Car Rental, said.

　　Yan Daoyuan said that at present, more than 1,100 pure electric vehicles have been invested in Wuhu, and more than 200 car rental points have been set up, which are spread all over the urban area of Wuhu. Consumers can basically walk within 10 minutes, and it is very convenient to pick up and return the cars.

　　"For example, if you go to work every day, you can inquire about the car rental point near your home through the mobile APP, walk for 5 to 10 minutes, and then return the car at the car return point near the unit. It is also a 5 to 10 minute walk. It is convenient to go to the unit and pay the fees online." Yan Daoyuan said that at present, there are 1,500 charging piles, which can provide charging service for 300 vehicles at the same time, and the vehicles are configured according to the ratio of one thousandth of the permanent population. In the future, a total of 5,000 pure electric vehicles will be put into Wuhu, further increasing the construction of car rental points.

　　Yan Daoyuan said that the current costs include land, maintenance, labor, electricity consumption, car purchase and other expenses. At present, in terms of income, only car rental fees are charged, and consumers are not charged other fees such as charging fees and parking fees.

　　Some experts said that there is a great demand for travel between 25 km and 100 km in the city, but there is no public solution now. In addition, the current utilization rate of private cars is only about 7%, while time-sharing can increase the utilization rate to 40% to 60%. It is estimated that the future time-sharing market will be hundreds of billions of yuan.

　　"At present, this model of easy car rental has formed a small ecological environment for sharing traffic in an urban area, which can be promoted and replicated in other small and medium-sized cities across the country." Yan Daoyuan said that not only small and medium-sized cities, but also Easy Car Rental has planned to enter the Beijing market. "The situation in Beijing and Wuhu is fundamentally different, including the cost of distribution will be greatly increased, but with the city’s demand for improving the environment and people’s fast and green travel, the promotion of new energy vehicles will go a long way." He said.

　　It is expected that the target of 5 million vehicles is expected to break through.

　　Good policies, good models, and good products and services are also needed. A few days ago, the National Development and Reform Commission approved the pure electric passenger car construction project of Beijing New Energy Automobile Co., Ltd., which is considered to be the first new energy vehicle production qualification in China. At the same time, the super pure electric sports car developed by BAIC Group in the R&D center in Barcelona, Spain has started field testing. At the Beijing Auto Show at the end of this month, BAIC’s driverless technology will also be available.

　　"5 million vehicles is a planned goal of the government. We think this may be faster. The most important reason is the progress of technology and the reduction of costs. With the improvement of product research and development and supply chain systems invested by major automobile companies, the scale effect is becoming more and more obvious." Zhang Yong said.

　　Some experts say that in the next three to five years, the private market in first-and second-tier cities will start rapidly, and the vast third-and fourth-tier cities and developed rural cities also have the demand for pure electric vehicles, but there are no suitable products to meet them, which will be replaced by some low-speed electric vehicles. If there are pure electric vehicles with appropriate cost performance, there will be a good market.

　　Under such a market prospect, the performance of the new energy automobile industry has also performed well. According to incomplete statistics, among more than 50 companies related to the new energy automobile industry that have published annual reports and performance reports in the A-share market, nearly 40 have achieved year-on-year growth in net profit. "We believe that the domestic new energy vehicle market will be better than the target of 5 million vehicles in the future." Zhang Yong said.

　　Reporter Li Zhiyong

　　CCTV News:In the development process of hydrogen energy industry, reducing cost and ensuring safety are two core concerns. In the face of this emerging industry, how to answer the public’s concerns? Let’s take a look at the answers given by the guests in the "On Tao" column.

　　Reduce industrial costs

　　Dong Yang, First Vice President of the World Automobile Organization and former Executive Vice President of China Automobile Industry Association:It is still more expensive than this gasoline car, even more expensive than the ordinary battery car. However, I will tell you that there is such a rule in automobile production. After you reach this scale of hundreds of thousands and millions, its cost will drop to one tenth of the original. Or this aircraft engine is the price of gold, and the car engine, with the same technology, is the price of cast iron.

　　Zhang Weidong, Director of Energy and Environment Project of the United Nations Development Programme:According to some experts, the cost of battery stack is 11,833 yuan per kilowatt now, and it will reach 668 yuan by 2025, which will be lower.

　　Dong Yang:Compared with the internal combustion engine, the fuel cell stack is basically a quasi-static or quasi-dynamic process, and many processes are very similar, but there is no reason to say that the stack must be more expensive than the internal combustion engine. Now it is only a matter of technical maturity and market capacity.

　　Zhang Xiaoqiang, Executive Vice President and Executive Director of China International Economic Exchange Center.To solve the cost problem of hydrogen production, if we don’t have a reasonable framework in terms of electricity price and so on, it may trouble enterprises for a long time, that is, the cost can’t be reduced. How can we have a reasonable electricity price system? For example, when using off-peak electricity, can we make it cheaper enough, so that large users can establish such a direct purchase and sale relationship, instead of adding this network fee through the power grid, resulting in high cost. Many aspects like these need government guidance.

　　For another example, we now attach importance to the utilization of hydrogen energy, especially hope that it can transform renewable clean energy, that is, water, wind and light. According to the characteristics of China, water, wind and light are concentrated in the southwest and northwest. Therefore, under the guidance of the government, we established a large-scale project in the world in the past. We called it "West-to-East Power Transmission and West-to-East Gas Transmission". Then, the next step is how to cooperate with this kind of energy and pipe network facilities in existing countries and explore in some ways. By participating in power transmission and gas transmission, and exploring new long-distance transportation of liquid hydrogen, for example, we can clean the energy in the northwest and northeast regions where energy is abundant. Apart from local consumption, because our main and most developed area is in the east, to solve these problems, I think many of them need the government to do a good job.

　　Safety standard operation

　　Guo Liejin, Academician of China Academy of Sciences:Everyone is very concerned about safety. When we were in primary school, our teacher would tell us that hydrogen would explode. The concentration of hydrogen, the concentration in space is 13% to 90%, and it is likely to explode between them. However, there is a premise for explosion. It needs to see an open flame with sufficient concentration. In Toyota and related enterprises, they all talk about the same car in their reports, which is a car filled with gasoline and a car filled with hydrogen. The chassis structure is the same. They do experiments. Under the premise of causing an explosion, the explosion of the gasoline car is completely destroyed, while the whole structure of the hydrogen fuel cell car is basically unchanged. Therefore, from this safety point of view, hydrogen fuel cell vehicles are much safer than our diesel gasoline vehicles.

　　The US Department of Energy and NASA have also done the same experiment. A barrel of gasoline, a barrel of diesel oil and a barrel of liquid hydrogen are shot from a distance, and then various protective facilities are built around to see who has strong explosive ability. The damage degree of the hydrogen tank after explosion is less than half that of the first two tanks, which is between 30% and 40%. What is the reason? Because hydrogen itself is a very light thing, once it is released, it runs into the sky and you can’t find it.

　　I have a personal experience. In 1997, I started to build facilities for hydrogen energy research in my State Key Laboratory. At that time, I was also worried about safety. I installed explosion-proof facilities on all the windows of the laboratory, and put hydrogen sensitive elements called sensors at key points around me, and I debugged them myself. Then when the concentration reaches a certain level, it will call the police and the fan will directly discharge the things. But it’s been twenty-two years since this year, and it hasn’t exploded, even ringing.

　　We operate according to the rules. Don’t our gas stations have many rules? It is also dangerous goods. Why can we do it well? Hydrogen can also be done very well, and even its destructiveness is much smaller than the fuel we use now. So recently, several hydrogen refueling stations in the world have reported explosions, such as those in California, South Korea and Europe, but when you read its reports, the final result is that the harm to people is minimal. Moreover, it is not the explosion of the fuel body itself, but the auxiliary device, which is caused by irregular operation or irregular installation. So in itself, as an energy source, you can use hydrogen with confidence, but you must of course obey the rules.

　　Dong Yang:This safety mainly depends not on whether the fuel can catch fire, but on whether you have mastered the norms and whether human beings have mastered the laws. Therefore, we must pay attention to the safety issue, which is the top priority for us to develop fuel cell vehicles. It is to do it seriously, accumulate experience, solve it, and monitor it with the industrial chain and life cycle, which can completely solve this problem.

Special feature of 1905 film network　In this decade, from fireworks to prosperity in the world, movies have always been in our lives. This decade, the film is life, life is film, this decade, our film life.

A movie, like a mirror, reflects the inner world of the viewer. Actors find their own colors from the characters; Wang Xiaoping, a movie fan, will substitute himself into the role and advance and retreat with the role.

"I love movies because it opens my world." Wang Xiaoping is a kindergarten teacher and a movie fan. When she was a child, she lived on an island and it was inconvenient to communicate with the outside world. The film became a window for her to know the world. When her parents took her as a child, she went to the surrounding villages to watch open-air movies and watched almost everything she could. On the other side of the sea is the road to Ningbo. Occasionally, her parents will take her there by ferry to see a movie. For her, it is like Chinese New Year.

In the ten years since 2012, a bridge has been built between the island and Ningbo, and the transportation is convenient. Now Wang Xiaoping can drive back and forth at any time, which is very happy for her as a movie fan. In addition to making it easier to go to Ningbo to watch movies, a modern cinema was built on the island in 2018. Since the establishment of this cinema on the island, Wang Xiaoping has watched more movies, and none of the new films he wants to see will be left behind.

Wang Xiaoping likes movies. As a kindergarten teacher, she also likes to chat with children in primary schools. Many movies can resonate with them. For example, these movies touched her deeply, and children also said that they were moved by them. Every year on Children’s Day in kindergarten, we watch movies together. Wang Xiaoping organizes everyone to make posters and set up stalls to buy tickets. Students can also go to other classes to watch movies.

Wang Xiaoping usually talks with children about domestic animated films. For example, Wang Xiaoping will use the characters with great personality in these films in art classes. She will pass on the good stories and characters in the films to students through her teaching life such as music and art. In her view: "I watched so many movies and experienced so many lives. I know that the movie brought me more than just a temporary touch. A good movie is a lifetime treasure for me, because my heart is full of passion and warmth. "

Wang Xiaoping’s practice of inspiring children through animated films made Youhao Zhang, as an anime fan, feel very cordial. Youhao Zhang grew up watching cartoons produced by Shanghai Fine Arts Studio when he was a child. At that time, the school rarely showed movies to children. Seeing that many schools now use movies to assist teaching, Youhao Zhang felt very envious.

Ten years ago, Youhao Zhang studied broadcasting at school. He was admitted to a school in Beijing as he wished. But when he was a freshman, he had deep doubts about himself and didn’t know how he could pass the teacher’s exam. When he was a sophomore, he began to read characters and scripts, and came into contact with classic plays such as Four Generations under One roof and Thunderstorm. He gradually felt that he could read the people in the scripts and understand their inner world. Later, he successfully graduated from the Central Academy of Drama and embarked on the road of being an actor.

When he saw the script, Youhao Zhang felt that it was a play he had to fight for, and the role in the script was highly compatible with himself. Then he wrote a long letter about his thoughts on Xiao July and the whole The Eight Hundred after watching the role. This is the first time he feels that he has devoted himself to creating a role — — What kind of person he should be and what kind of emotion he should be endowed with.

Later, Youhao Zhang began to enter the core team of creation, and felt his responsibility and obligation to do his work well. He is also very grateful to the distinguished people he met along the way. They conveyed a very important idea to him, that is, don’t lose the color of himself. The reason why he was chosen to play a certain role is that he has something that makes others feel different.

Movies are a way to open the world. Movies can be used to inspire children’s hearts and let people find themselves in them.
