More than ten days after the Mayday concert, a huge wave of suspected lip-synching hit.

On November 30th, bloggers in bilibili released a video entitled "Identification of 12 Songs of Shanghai Concert in May", saying that six songs were suspected of lip-synching, and five of them were lip-synching.

A stone stirs up a thousand waves. Although the concert in the mainland has ended in May, the criticism has not died down. On December 4th, Mayday Weibo, a brokerage company, issued a statement saying that Mayday did not lip-synch during the tour, and the comments on "Mayday lip-synching" on the Internet were malicious attacks, rumors and slander, which seriously damaged the artist’s image. "Our company is actively cooperating with relevant law enforcement departments to carry out investigations, and I believe relevant departments will give us a fair result to set the record straight".

On the same day, the Law Enforcement Corps of the Shanghai Cultural Tourism Bureau said that it attached great importance to the alleged "lip-synching" sensation, and requested the organizers to cooperate with the investigation in accordance with the Regulations on the Administration of Commercial Performances. After the relevant situation was verified according to law, it would respond to the concerns of netizens in a timely manner.

Behind the lip-synching storm is the concert fever that continues to have a high fever this year. The Beijing News Shell Finance reporter combed and saw that since May, Mayday has sung in 12 mainland cities including Beijing, Hangzhou, Wuhan, Shenzhen and Shenyang, with 47 performances. Among them, there were 9 concerts in September.

The country is singing intensively, and the ability to absorb gold cannot be underestimated. The audience of eight performances in Shanghai reached 360,000. Even if the ticket income is calculated according to the lowest fare, the ticket income will easily exceed 100 million.

Mayday agency believes in music statement.

Intensive tour, singing 47 times.

May Day lip-synching is controversial and has been fermented for several days.

On November 21st, the last concert of "I really want to see you" in Shanghai Station on May Day came to an end. There were 8 concerts in Shanghai Stadium this May. According to Mayday Music, the total number of concerts in Shanghai is expected to reach 360,000.

On the second day after the concert, some self-media bloggers said that they had received a submission about lip-synching of the Mayday concert, but it didn’t arouse much splash. Until November 30th, a blogger in bilibili released a video about "Identification of the true and false singing of 12 songs in the Shanghai Concert on May Day". In the video, the blogger pointed out that six songs, Cheers, Being in Love, Being Satisfied, Missing Lover, Writing This Song for You and Don’t Listen to Slow Songs for Sad People, were suspected of lip-synching, and five of them were lip-synching.

Rumors of lip-synching are getting worse. On December 3rd, Believe Music said in Weibo that the Paris Concert on May Day would be broadcast live all the time, "singing for three hours all the time, and really singing until dawn". This voice did not respond positively to the controversy. Some netizens in the comment area said, "The whole live broadcast can’t prove that it was a real singing before."

How hot the performance market has been this year, Mayday is undoubtedly a microcosm.

In May, as the first stop in the mainland in 2023, six concerts were held in Beijing Bird’s Nest on May Day. It is believed that the number of people watching music reaches 100,000 each time, and a total of 600,000 people watch the performance.

According to the rough statistics of Shell Finance reporters, after the Beijing concert, Mayday took a short "rest" for 14 days and then devoted itself to an intensive mainland tour. From May to November, Mayday held the most concerts in September, with a total of 9 concerts. The performance cities included Xi ‘an, Nanjing and Chongqing. Followed by June, October and November, with 8 games respectively, during which they traveled to Beijing, Hangzhou, Guangzhou, Chengdu and Shanghai. In contrast, the least performance was in August, with only three performances.

On December 4th, Shell Finance reporter saw in official website’s "Mayday 2020-2024 World Tour" released by Belief Music that since May, Mayday has performed in 12 mainland cities, with 47 performances, and concerts in many cities often have three or four performances in succession.

It’s not new to travel to many cities in a short time in May. After the concert in Hangzhou ended in June this year, I went to Wuhan to sing nonstop in May, only two days apart. According to the statistics of Shell Finance reporters, during the tour, the longest stop time in May was 37 days, while the last concert in Shanghai was 20 days away from the previous one, and the opening dates of other cities ranged from 3 to 16 days.

It is believed that music is publicly announced. After the Shanghai concert, from November 28th, 2023 to January 14th, 2024, Mayday will also be sung in London, Berlin, Paris and other cities.

One ticket is hard to find, and hundreds of millions of ticket revenues.

Singing frequently in May, the ability to attract gold can not be underestimated.

In August this year, Mayday held three concerts in Quanzhou, Fujian, attracting a total of 120,000 people, about 70% of whom were from other places. The ticket revenue was nearly 100 million yuan, which brought more than 200 million yuan to the local tourism, transportation, catering and accommodation markets.

In November, tickets for the Shanghai Concert on May Day ranged from 355 yuan to 1,855 yuan, with a total of 360,000 participants. Even with the lowest ticket price for eight performances, the ticket revenue can easily exceed 100 million.

Fans are after it, and it is hard to get a ticket for the Mayday concert. The concert held in Beijing on Mayday at the end of May was to sing again after a lapse of four years. A Mayday fan told Shell Finance reporter, "Now, if you want to get tickets, you can only buy them from scalpers at a high price." With the heat soaring, the original price of 355 yuan stands tickets, the sales price reached 900 yuan. However, the original price was unified to 1855 yuan, and the tickets in the front of the infield were priced from 3850 yuan to 8800 yuan according to the distance of the seats.

Shell financial reporters found that Mayday concerts in Hangzhou, Xi ‘an and Guangzhou were exposed to many people selling scalper tickets.

The craze hit, and it also ignited the vicinity of the Mayday concert. Among them, the official single light stick 2.0 is sold in 140 yuan, and the combination price of light stick+protective cover is 190 yuan. It is reported that the light color of the light stick will be converted into different colors with the central control panel during the concert, so it is favored by many fans. It is believed that music, this light stick is sold online and offline through multiple channels.

The reporter of Shell Finance saw that the Taobao store of "Straw Mall", one of the channels, showed that this luminous stick had sold more than 9,000 orders.

In addition, it is believed that the official flagship store of Music Taobao shows that the store is selling 29 Mayday peripheral products. The cheapest one is "Inflatable Cushion Around Mayday FLYTO2021 Concert", which costs 55 yuan, and the most expensive one is "May Day 2023 Noah’s Ark Concert NOW&HERE Limited Edition Gift Box", which costs 635 yuan and has sold more than 100 orders, which is the highest-selling single item in the store.

Concert economy involves complex industrial chain.

Eye-searching shows that Believe Music Culture Media (Beijing) Co., Ltd. was established in 2007 with a registered capital of 2 million yuan, and the legal representative Xie Zhifen holds 92.5% of the shares of the company. Believe Music official website shows that the business of believe music covers record production, artists’ agency and concert production. Its artists include Jonathan Lee, Rene Liu, Mayday and Gaowu.

Shanghai Yunhua Culture Development Co., Ltd., the organizer of Mayday Shanghai Concert, was established in 2019 with a registered capital of 10 million yuan and legal representative Yu Feifei. The company is wholly owned by Shanghai Chinese Culture Performing Arts Co., Ltd.

According to the consulting report of Ai Media, with the resumption of offline concerts, the performance market is picking up in an all-round way. With the promotion of domestic economic development and cultural consumption upgrading, the radiation effect of performance economy continues to enlarge, and the performance market in China is expected to reach 90.346 billion yuan in 2023.

Jiang Han, a senior researcher at Pangu think tank, told Shell Finance reporter that since the beginning of this year, the situation that concert tickets are constantly being speculated but one ticket is still hard to find has aroused widespread social concern. There are multiple reasons behind the popularity of concerts and the high ticket prices. First of all, with the gradual recovery of the entertainment market, a large number of cultural and entertainment needs have been released, and the concert market has been loved by consumers because of its unique live experience and star effect. Secondly, the contradiction between supply and demand in the concert market is obvious, and the number of concerts and seats is limited, which leads to the shortage of tickets, which also leads to the increase of fares to some extent. In addition, scalper speculation has also aggravated the tension of concert tickets.

In Jiang Han’s view, the concert economy is actually a rather complicated industrial chain, involving multiple stakeholders. Among them, the most important source of income is ticket sales. Artists can formulate the ticket price strategy according to their own popularity, the scale and time of the concert, and attract different levels of audience to buy. In addition, commercial sponsorship and derivative sales are also an important source of income.

From the perspective of stakeholders, the chain involved in concert economy includes: artists themselves, brokerage companies, organizers, ticketing agents, sponsors, etc. Each role has its specific functions and interests. There is an intricate interest chain behind the concert economy, and all links are closely linked. If you want to dig gold in the concert market, you need to understand this interest chain and find a suitable positioning and strategy.

Zhang Yi, CEO and chief analyst of Ai Media Consulting, told Shell Finance that the concert economy is sustainable, and the market demand and local consumption demand will stimulate the continued growth of the concert economy, and the growth rate may decline to some extent, but it is also a normal phenomenon.

Regarding the lip-synching storm, lawyer Lan Tianbin, a senior partner of Jiangsu Fade Dongheng Law Firm, told the Shell Finance reporter that if the audience is deceived by lip-synching, the audience has the right to ask the performance organizer to compensate for the losses in accordance with the laws and regulations on the protection of consumer rights and interests after the exit; The performance organizer may claim compensation from the responsible performing arts groups and actors according to law. In addition, the cultural administrative department of the people’s government at the county level shall impose a fine of 50,000 yuan to 100,000 yuan; Those who provide conditions for lip-synching by actors shall be fined between 5,000 yuan and 10,000 yuan by the competent cultural department of the people’s government at the county level.

　　Recently, the research report of relevant institutions pointed out that palm oil will produce more chloropropanol esters and glycidyl esters than other vegetable oils in the process of high-temperature refining above 200℃. Subsequently, some media reports about the toxicity of chloropropanol ester and glycidyl ester in food attracted consumers’ attention. A few days ago, china food and drug administration released the second issue of Food Safety Risk Analysis in 2017, and organized relevant experts to interpret it.

　　Chloropropanol ester is the esterification product of chloropropanol compounds and fatty acids, which can be divided into 3- chloropropanol ester (3-MCPD ester), 2- chloro -1,3- propanediol ester (2-MCPD ester), 1,3- dichloro -2- propanol ester (1,3-DCP ester) and 2,3- dichloro according to the different types of chloropropanol. In recent years, it has been found that 3- chloropropanol esters are detected in cereals, coffee, fish, meat products, potatoes, nuts and hot-processed fatty foods with vegetable oil as raw materials. Especially, the reports of detecting 3- chloropropanol ester in refined vegetable oil and other foods are increasing gradually. Glycidyl ester is the esterification product of fatty acid and glycidyl ester. It is a twin brother with chloropropanol ester, and its formation mechanism is similar. In the process of oil refining, glycidyl ester is usually formed together with 3- chloropropanol ester, and the content of 3- chloropropanol ester is high, so is the content of glycidyl ester. 3- chloropropanol ester and glycidyl ester have become the new pollutants of vegetable oil that attract worldwide attention.

　　Second, some studies believe that these two substances have a low risk of harm to human health.

　　At present, the toxicological research on 3- chloropropanol ester and glycidyl ester is not systematic. The Hong Kong Centre for Food Safety assessed the exposure of people according to the content of 3- chloropropanol esters in biscuits, vegetable oils, cakes and other foods, and concluded that the health risks of 3- chloropropanol esters ingested through the above foods did not need special attention. The German Institute for Risk Assessment assessed the risk of glycidyl ester intake by European people through vegetable oil, and concluded that glycidyl ester intake by the general population through vegetable oil does not pose a safety risk to health. At present, the published research data in China also believe that the risk of glycidyl ester intake by the general population through food such as vegetable oil is low.

　　3. At present, there is no international limit standard for these two substances.

　　3- chloropropanol ester may be hydrolyzed into 3- chloropropanol in vivo. In 2012, the Joint Expert Committee of Food Additives of the Food and Agriculture Organization of the United Nations (FAO)/ World Health Organization (WHO) formulated the tentative maximum daily tolerance (PMTDI) of 3- chloropropanol as 2μg/kg per kg body weight. However, the corresponding limit standards for 3- chloropropanol ester and glycidyl ester have not yet been formulated.

　　Fourthly, optimizing the refining process can reduce the content of these two substances.

　　The results show that the content of 3- chloropropanol ester in oil processing raw materials and unrefined vegetable oil is extremely low, but the content of refined vegetable oil increases significantly, and its content level is related to the types of raw materials of crude oil. Compared with corn oil, rapeseed oil and soybean oil, vegetable oil with pulp as raw material, such as palm oil, is more likely to produce 3- chloropropanol ester. Optimizing the production process can reduce and control the production of 3- chloropropanol ester and glycidyl ester in vegetable oil refining.

　　Therefore, experts suggest: First, strengthen analysis and research to provide scientific basis for whether it is necessary to formulate limit standards for these two substances. Second, according to the characteristics of different oil raw materials, for example, some oils are suitable for cold pressing and some are suitable for hot processing, and different processing methods are established. Moderate processing can reduce the formation of harmful substances and avoid the excessive formation of various risk factors. Third, consumers should pay attention to nutrition collocation and food diversification in their daily diet, and take vegetable oil according to the dietary guidelines of China residents (2016) to avoid excessive intake.

1905 movie network news The family comedy will be released on August 17. Today, the film released "Wu Mengda Special", which reveals Wu Mengda’s daily life in the Oolong Hospital, accompanied by old classic passages interspersed from time to time, and also tells how Uncle Da "turned around gorgeously" from the eldest brother to the abbot, Master Changmei.

Hong Kong-style nonsense hilarious upgrade "Uncle Chao" Wu Mengda plays cross-border

In 1994, when "Oolong Courtyard" became popular all over Asia, it was the golden age of Hong Kong-style nonsense comedy, and many of the scenes in the film became classics. For example, Wu Mengda’s eldest brother played "Kiss Goodbye" affectionately in front of Muse Xiaohong’s window, but was hammered by the squatting master to escape in embarrassment, exposing the short plot of the tape recorder "lip-synching". The reversal continued to cause hilarious laughter, and it has been talked about by fans to this day. As the star Wang Ning said: "When you mention the old version of Oolong Courtyard, it feels like you just watched it yesterday."

Compared with the old version, "New Oolong Academy" is not only more detailed and refined in hardware such as setting the scene, but also has a new upgrade in story, character identity and character, including nonsensical elements. Wu Mengda has changed from a "six unpurified" senior brother to an abbot, Master Changmei, who dedicated his love to Aidou; "full of literary bacteria", he is still a live stream celebrity, which is the most in "slash old man". As shown in the special, Master Changmei has nothing to do on weekdays to pick the girl group SHE, play CALL for idols, and interact with fans in the live stream anytime, anywhere. Even if it is on fire, he is busy rescuing fans’ letter gifts. The traditional impression of a "highly respected" abbot is combined with the current fan culture, live broadcast and other fashionable fresh elements, colliding with the spark of Hong Kong-style nonsense comedy. Wu Mengda said that this is a "crazy" movie, and when we act in this movie, we all feel rejuvenated.

Top team comedian amused summer, super 700,000 netizens look forward to the strongest family fun

In addition to bringing together Wu Mengda, Hao Xiwen and Ye Quanzhen and other original members of "New Oolong Court", there are also top domestic comedy team members such as Happy Twist, Wanhe Tianyi and Benshan Media to join, serving the audience a cool comedy feast. Wang Ning has won the championship of "Happy Comedian"; "Kong Muse" Kong Lianshun has grown up all the way from popular comedies such as "Never Expected"; Song Xiaobao has appeared in many variety shows in recent years as a "funny handle" and created countless classics. This time, he interacted with Li Xinrui, a member of "New Laughing Forest Kid", in and out of the play, and his ability to amuse was not reduced. In addition to "Qiuya Muse" Wang Zhi, Zeng Zhiwei and other comedians, even if the summer blockbuster is intensively bombarded, "New Oolongyuan" is definitely worth watching. Moreover, the film "Xiaoguo" is suitable for all ages, and the theme is warm and relaxed. It is undoubtedly the first choice for family viewing. At present, the whole network wants to watch the index 700,000, and netizens have shown their expectation and support for the film with practical actions.

Over the years, Wu Mengda’s masterpieces have been continuous but often played "golden supporting roles". This time, Wu Mengda will play the lead role for the first time in "New Oolong Academy", which not only offers superb acting skills, but also earns the respect and admiration of younger actors. Kong Lianshun said: "Generally speaking, you will feel a lot of pressure when you play with old seniors and old actors, but Uncle Da is very kind, and he will guide you when filming. After playing with him, you will not feel stiff, but feel very comfortable and natural." Now that Uncle Da is 65 years old, due to his increasingly poor health in recent years, many loyal fans have also called on everyone to support "New Oolong Academy" starring Uncle Da on the Internet: "We owe Uncle Da a movie ticket".

　　The core of the new round of energy revolution is renewable energy generation and large-scale energy storage. Among many electrochemical energy storage technologies, sodium ion battery is one of the ideal choices for large-scale energy storage because of its rich resources, low cost, high safety, high conversion efficiency, flexibility, convenience, easy integration, fast response and maintenance-free.

　　— — Hu Yongsheng, researcher of Institute of Physics, Chinese Academy of Sciences, founder and chairman of Zhongke Haina.

　　Recently, high-tech enterprises such as Zhongke Haina Technology Co., Ltd. (hereinafter referred to as Zhongke Haina) and Huayang New Materials Technology Group Co., Ltd. hatched by Institute of Physics, Chinese Academy of Sciences signed a contract with the Management Committee of Shanxi Transformation Comprehensive Reform Demonstration Zone to build a production line for anode and cathode materials of sodium ion batteries with an annual output of 2,000 tons in Taiyuan.

　　On February 20th, Hu Yongsheng, a researcher at the Institute of Physics of Chinese Academy of Sciences and the founder and chairman of Zhongke Haina, said in an interview with the Science and Technology Daily reporter that China’s sodium ion batteries are in the forefront of the world in terms of technology research and development such as material system and battery comprehensive performance, as well as in terms of industrialization speed, demonstration application, patent layout and standard formulation, and have already had the first-Mover advantage.

　　New energy nova is accelerating on the road of industrialization.

　　The development of fossil energy such as coal, oil and natural gas has led to the rapid development of human society, and the progress of modern non-fossil energy is also triggering a new round of energy revolution. Who will be the protagonist this time?

　　The voice of lithium-ion batteries is very high. However, when lithium-ion batteries are widely used in more and more fields in China, an unavoidable problem is becoming more and more worrying — — China’s lithium resources are highly dependent on imports. It is necessary to develop energy storage battery technology which does not depend on rare resources and has low cost.

　　Sodium ion battery, which is closest to lithium ion battery technology, has begun to emerge. In recent years, related achievements with independent intellectual property rights have emerged continuously. Intelligent electric bicycles, low-speed electric vehicles, home energy storage cabinets, energy storage power stations and sightseeing electric vehicles in parks/scenic spots with sodium ion batteries as the "heart" have come out one after another, and many achievements have been released for the first time in the world.

　　In the "Top Ten Scientific Progress in China in 2020" recently organized by the High-tech Research and Development Center of the Ministry of Science and Technology, sodium ion battery research was selected as 30 candidate results.

　　As a new star of new energy, sodium ion battery is accelerating on the road of industrialization, or it will become an opportunity for China to lead a new round of energy revolution.

　　"Sodium" attracts talents to make up for the lack of "lithium"

　　Globally, the distribution of lithium resources is extremely uneven, with about 70% distributed in South America. Available data show that at present, 80% of lithium resources in China depend on imports.

　　"Although lithium-ion batteries have become ‘, which accounts for 80% of the global electrochemical energy storage scale market; Absolute first brother ’ However, the scarcity of its resources and high cost have led to the large-scale development of its industry facing the ceiling. " Hu Yongsheng said in an interview with the Science and Technology Daily reporter.

　　How to solve the problem? It is urgent to find a cheap substitute.

　　Therefore, sodium ion batteries with the same working principle and similar battery components as lithium ion batteries have ushered in a great development opportunity.

　　Similar to lithium-ion batteries, sodium ion batteries rely on the reversible stripping and embedding of sodium ions between positive and negative electrodes to realize the storage and output of electric energy.

　　Sodium resources are extremely abundant in the earth’s crust, and the abundance of the earth’s crust is more than 1000 times that of lithium. Sodium ion batteries have shown significant advantages in cost. If the same energy is stored, the cost will be about 30% less than that of lithium ion batteries. Because of the similar battery structure, most of the existing lithium ion battery production equipment can be directly put into the production of sodium ion batteries, which further improves the cost control.

　　In the process of industrialization, low price is very important, but good quality is more important. Hu Yongsheng told the Science and Technology Daily reporter that the comprehensive performance of sodium ion batteries shows multiple advantages.

　　With the deepening of research, researchers found that sodium ion batteries have good power characteristics, wide temperature range adaptability, safety performance and no discharge problems. In addition, both the anode and cathode of the sodium ion battery can adopt aluminum foil current collectors, which can further improve the energy density of the sodium ion battery and make the sodium ion battery move towards the direction of low cost, long life, high specific energy and high safety.

　　Hu Yongsheng, for example, now commonly used mobile phone lithium-ion batteries can be fully charged in about one hour, while sodium-ion batteries can be fully charged in ten minutes or even less. It is frequently reported that lithium-ion batteries go on strike at low temperature in winter, while the discharge characteristics of sodium-ion batteries are still very good in the environment as low as -30℃ and as high as 80℃, which shows that they are environmentally friendly, very "sturdy" and can withstand tossing. "We have done experiments, using a steel needle to pierce the sodium ion battery, artificially shorting it, and found that there was no fire or explosion."

　　Cheap, "sturdy" and safe, sodium ion batteries are likely to become an important supplementary technology for lithium ion batteries in the future.

　　Breaking the technical bottleneck and broadening the application scope

　　Positive electrode, negative electrode and electrolyte are the three elements of sodium ion battery. Among them, most cathode materials face bottlenecks such as poor stability, short cycle life and high cost.

　　In order to solve these problems, the research team of Hu Yong Sheng bypassed the high-priced elements such as nickel and cobalt, which are commonly used as cathode materials for lithium-ion batteries, and used common elements such as copper, iron and manganese, and developed a layered oxide cathode material system for sodium-ion batteries with low cost, high stability and long service life.

　　Previously, the team cooperated with international scholars and published the research results on the cathode materials of sodium ion batteries for the first time in Science magazine.

　　Relying on the sodium ion battery technical team of the Institute of Physics, Zhongke Haina was established in 2017, becoming the first high-tech enterprise in China to focus on the R&D and production of sodium ion batteries. At present, Zhongke Haina has been financed twice, totaling 58 million yuan, for pilot technology development, and has built a 100-ton pilot test line for anode and cathode materials of sodium ion batteries and a million ampere-hour battery core line, and developed many products, such as soft bags, aluminum shells and cylindrical batteries, with energy density of 100— Between 150 watt-hours per kilogram, it is more than 3 times that of lead-acid battery, and its cycle life is more than 4500 times. Not long ago, the Science and Technology Cooperation Center of Beijing Municipal Science and Technology Commission organized an expert group to accept the project it undertook. The evaluation given by the expert group was that the relevant technical indicators reached the international leading level.

　　At the end of 2017, the team developed a 48V/10Ah sodium ion battery pack for electric bicycles; In 2018, the team developed a 72V/80Ah sodium ion battery pack and launched the world’s first sodium ion battery electric vehicle.

　　It is reported that the team has obtained more than 20 patents authorized by China on key materials such as positive electrode, negative electrode, electrolyte, additives and adhesives (some patents have been authorized by the United States, Japan and the European Union), and published more than 100 papers in academic magazines such as Science and Nature, which have been cited for more than 10,000 times.

　　These scientific research achievements will also play the role of engines, and will be transformed in a series of incubation enterprises such as Zhongke Haina, providing inexhaustible power for the commercial development of sodium ion batteries.

　　High hopes are placed on scale energy storage.

　　Climate change is a global problem facing human beings, so China has put forward the goal of carbon neutrality in 2030 peak carbon dioxide emissions and 2060, which also means that China’s economy and society will usher in a comprehensive low-carbon change.

　　In 2017, Chen Liquan, an academician of China Academy of Engineering, put forward the idea of "electric China". This coincides with China’s advocacy of building a global energy internet to meet global power demand in a clean and green way.

　　So, here’s the problem.

　　Solar energy and wind energy are the main renewable new energy sources to generate electricity, but they are random, intermittent and fluctuating. Solar panels can generate electricity in sunny days and during the day, but on cloudy days and at night, they "stop eating". Wind power generation is also closely related to wind power and weather. However, nowadays, we can’t leave electricity for a moment, and we can’t stand the days when electricity is only available when the weather is "awesome".

　　There is an urgent need for large-scale energy storage devices, mainly energy storage power stations, to store surplus electric energy and use it when power generation is insufficient to ensure a stable supply of electricity.

　　At present, the lithium-ion battery is the "first brother" in the energy storage demonstration power station. However, due to various restrictions mentioned above, the lithium-ion battery cannot support the two huge markets of electric vehicles and large-scale energy storage at the same time. Therefore, Academician Chen Liquan and researcher Hu Yongsheng have high hopes on the sodium-ion battery.

　　In 2019, Zhongke Haina launched the world’s first 100 kWh sodium ion battery energy storage power station, which realized the demonstration application of sodium ion battery in large-scale energy storage for the first time.

　　"peak carbon dioxide emissions and carbon neutrality are China’s solemn commitments and opportunities to lead the third energy revolution." Hu Yongsheng pointed out that the core of the new round of energy revolution is renewable energy power generation and scale energy storage. At present, the former is close to maturity, while the latter is still developing. Among many electrochemical energy storage technologies, sodium ion battery is one of the ideal choices for scale energy storage because of its rich resources, low cost, high safety, high conversion efficiency, flexibility, convenience and easy integration, fast response speed and maintenance-free.

　　Due to the huge energy storage market and industrial demand, combined with China’s perfect lithium-ion battery industry chain, sodium ion batteries have already had the conditions to take the lead in realizing industrialization and commercialization in China.

　　"I believe that with the strong support of the top-level planning and related policies of governments at all levels in China, with the collaborative innovation of production, learning and research and the promotion of social capital, sodium ion batteries will surely play an important role in achieving the goals of peak carbon dioxide emissions and carbon neutrality." Hu Yongsheng said.

Skipping rope VS running, what are their advantages and disadvantages? Which sport should you choose to lose weight?

Skipping rope and running are very common aerobic exercises, which can help us lose weight, improve cardiopulmonary function and enhance physical fitness.

However, they are also different in many ways.Next, let’s discuss the advantages and disadvantages of skipping rope and running, and how to make a decision when choosing a weight loss exercise.

First, let’s look at the advantages of skipping rope:

1. Skipping rope is a very convenient and flexible sport. You don’t need too much space. You only need a rope to start exercising anytime and anywhere.

2, skipping rope can exercise the whole body muscle groups, including arms, abdomen, legs and other parts, which helps to improve the coordination and sensitivity of the body.

3. Sticking to skipping rope can also promote blood circulation, improve the body’s oxygen intake, effectively improve cardiopulmonary function and enhance the ability of the heart and lungs.

4, skipping exercise is more flexible, there are a variety of ways to play, which is more interesting, and can also help you lose weight and help you burn calories quickly.

However, skipping rope also has its disadvantages:

1. It may be difficult for some people, because it requires certain skills and balance.

2. Jumping rope requires higher vital capacity, and many novices can’t hold on for 2 minutes without panting.

3. When skipping rope, the knee needs to bear the pressure value of twice its own weight.

Next, let’s take a look at the advantages of running:

1. Running is a very low threshold aerobic exercise suitable for men, women and children. It can effectively improve the cardiopulmonary function, enhance physical fitness and lose weight.

2. Running can promote metabolism, accelerate fat burning and burn calories. Jogging for 1 hour every day can help you improve obesity.

3, running can also increase bone density, promote calcium coefficient, but also enhance the strength and endurance of leg muscles, so that your lower limbs are more flexible and powerful.

However, the disadvantages of running are also obvious:

1. Outdoor running is easily affected by the venue and weather. When the weather is too cold, the desire to run will decrease, and rainy days will also affect the enthusiasm of running.

2. Running has a great impact on joints, and the knee needs to bear 2.5-3.5 times the weight, so it may be uncomfortable for some people.

Should you choose skipping rope or running?We should make a decision according to our physical condition, interests and goals.

If you want to burn calories quickly and improve your body’s agility and coordination, skipping rope may be a better choice. If you have poor physical endurance, no sports experience and want to lose weight, then running may be more suitable for you.

No matter which sport you choose, you should pay attention to gradually increasing the intensity and time of exercise to avoid injury. At the same time, we should also pay attention to reasonable diet and rest to get the best exercise effect.

Sitting around a table with my family and eating a family reunion dinner cooked by them is probably what most people think of New Year’s Eve. However, there are a group of people who still stick to their posts on New Year’s Eve. Their persistence is to ensure the smooth travel of passengers from south to north. Kang Bin, director of the North Passenger Transport Workshop of Chongqing Railway Station, is one of them.

"The train arrived at 16: 08. Did you get all the gloves? Check it again, it’s sloppy. " At 15: 20 on January 24, Kang Bin said with a walkie-talkie. Then, he strode forward to the duty room and organized personnel to make relevant preparations.

At 15: 30, eight staff members arrived.

Wear masks, rubber gloves and goggles … Kang Bin and his colleagues skillfully put on protective tools and walked to the exit. "Everyone will be divided into 4 groups, 2 people in each group, take temperature one by one, wear protective gear and pay attention to safety." Along the way, Kang Bin kept telling the team members.

At 15: 40, all the team members are in place. Everyone stands in their positions, takes out hand-held temperature detectors, measures each other’s temperatures, and tests the instruments. After everything is in order, they wait for the outbound passengers.

At 16: 10, a large number of passengers emerged at the exit. Two staff members kept order at the scene and let everyone line up in turn. The staff members stood at the gate exit and took the temperature of each passenger. Kang Bin told chongqing morning post, an upstream news reporter, that there are now more than 40 trains that leave and stop in Wuhan every day (Wuhan keeps turning back immediately), and each train has at least 600 passengers. They have to take the temperature of the passengers on each train, and the workload is very heavy.

At 16: 30, the temperature measurement is over. Kang Bin returned to the office with the team members, took off his glasses, gloves and washed his hands … "Let’s rest for a few minutes, and the next bus is at 16: 26." Kang Bin said.

"Today, we have more than 200 people on duty, many of whom give up their vacations and rush to the front line without hesitation." Kang Bin said that at the age of 45, he is an old railway passer-by. He has been working for 23 years, and he can’t remember how many New Year’s Eve years he hasn’t been at home. Originally, he took a break on the 23rd. Because of special circumstances, he arrived at his post early at 23: 00 on the 22nd, and together with his colleagues, he went all out to do a good job in epidemic prevention and control.

"On New Year’s Eve this year, another group of colleagues spent it together." Kang Bin said that this year, colleagues agreed that everyone would bring a dish and have a "hundred-family banquet" together.
