77-year-old professor donates 82.08 million life savings: there are successors in scientific research.

  Professor Zelin Wang from Henan Agricultural University.

  Recently, the news that Zelin Wang, a 77-year-old professor at Henan Agricultural University, donated his life savings of 82.08 million yuan has attracted a lot of attention. On January 4th, Beijing Youth Daily reporter learned from Henan Agricultural University that after being transferred to Henan Agricultural University, Zelin Wang has successively obtained three invention patents and 12 new veterinary drug certificates without applying for funds, which has completely overcome many major poultry epidemic prevention problems.

  Not long ago, Zelin Wang proposed to donate all the remaining 82.08 million yuan from lifelong scientific research to the school.

  Obtained 3 invention patents and 12 new veterinary drug certificates.

  The conversion rate of scientific research achievements is 100%

  According to the staff of Henan Agricultural University, intensive aquaculture rose in China more than 40 years ago, but old diseases such as Newcastle disease broke out frequently, and new diseases such as avian influenza and bursal disease were introduced and spread rapidly, causing a large number of poultry deaths and seriously endangering the development of poultry industry. At the beginning of 1984, Zelin Wang was transferred to Henan Agricultural University, and innovatively carried out collaborative innovation in Industry-University-Research, and achieved rolling development in the form of cooperation with enterprises.

  In the past 35 years, Zelin Wang has made many achievements in scientific research and innovation without applying for funds from the state. He has successively obtained 3 invention patents and 12 new veterinary drug certificates, presided over the establishment of a major poultry disease virus germplasm resource bank, and created a concentrated inactivated vaccine research and development platform, which broke the foreign monopoly and completely overcame many major poultry disease epidemic prevention problems such as new and efficient Newcastle disease and infectious bursal disease, and was called "a domestic umbrella for China chickens".

  The research project "Development and Application of Highly Efficient Concentrated Combined Vaccine against Poultry Diseases" by Professor Zelin Wang from Henan Agricultural University also won the second prize of the National Science and Technology Progress Award in 2012. The Institute of Agricultural Economics and Development of Chinese Academy of Agricultural Sciences has made statistics on the projects studied by Professor Zelin Wang: within the calculation period of economic benefits, this achievement has created a total of 188.829 billion yuan for the society, with an average annual increase of 15.736 billion yuan for the society; The research expenditure per 1 yuan for this scientific research achievement can increase the net income of 115.81 yuan per year for the society within the calculation period of economic benefits, and the new economic benefits in recent three years are 78.996 billion yuan.

  At the beginning of 2014, it was learned that Professor Zelin Wang’s team was going to develop a new vaccine, and four companies immediately invested 19.5 million yuan to support it.

  According to reports, Zelin Wang’s scientific research achievements have been produced on a large scale in more than 20 famous biological products factories across the country, with a 100% conversion rate and an average annual economic benefit of more than 10 billion yuan. Zelin Wang and its independent legal entity have accumulated nearly 100 million yuan in achievement transfer funds and cooperation funds. At present, two listed companies need to pay 8% of their annual market sales as patent royalties to Zelin Wang and Henan Agricultural University for 12 consecutive years because they use Zelin Wang patented technology.

  Purchase advanced equipment and set up innovation fund.

  Zelin Wang donated research income several times.

  According to the school staff, despite the high income from scientific research, Zelin Wang’s personal life is very frugal. At present, the 77-year-old Zelin Wang goes out "if he can walk, he won’t ride a bike; if he can ride a bike, he won’t take a bus; if he can take a bus, he won’t take a taxi."

  Zelin Wang, who is worth nearly 100 million yuan, spends all his money on scientific research and public welfare. When he earned the first 4 million yuan, Zelin Wang used the money to gradually build two experimental buildings for the school, and purchased the most advanced high-speed centrifuges, overspeed centrifuges, low-speed large-capacity centrifuges, thickeners, freeze dryers and other advanced instruments and equipment in universities in the province at that time.

  In 2005, the income from the transfer of the new drug certificate developed by Zelin Wang was 5 million yuan. According to the agreement, apart from the income from schools and colleges, individuals and poultry institutes can get 3.45 million yuan. After he got the funds, he gave 2.3 million yuan to the Poultry Institute for laboratory construction, and later donated all the remaining money, of which 1 million yuan was donated to the Poultry Branch of China Animal Husbandry and Veterinary Society to set up an innovation fund to encourage young scientists to join the cause of poultry disease prevention.

  In 2015, two new drug certificates were acquired by two enterprises in Zelin Wang. According to the agreement, the enterprises will pay 8% of their annual sales as patent royalties to Zelin Wang for a period of 12 years. According to the income calculation in recent years, the conservative income in 12 years is 10 million yuan. However, in March 2019, Zelin Wang submitted a report to the school, and donated all the part allocated to him to set up the Institute’s scientific research and innovation fund.

  Not long ago, Zelin Wang once again found a school and expressed his willingness to donate all the remaining 82.08 million yuan from lifelong scientific research transformation to the school, hoping to build a high-level biosafety level III laboratory, commonly known as P3 laboratory in the industry.

  "My achievements were achieved under specific historical conditions. Without the support of reform and opening up, schools and colleges, and without everyone’s efforts, it would be impossible." Zelin Wang said, "I am old, but there must be successors in scientific research. The money will only be valuable if it is used where it is needed more."

The combination of "going out" and "bringing in" Jiangsu "agricultural name" frequently plays "open card"

  Jiangsu takes a global view to expand agricultural development, fully develops an open economy, seizes the opportunity of "Belt and Road" construction, and adheres to the combination of "going out" and "bringing in" to build a new pattern of open agricultural development.

  In order to speed up the development and improve the quality of open agriculture, Jiangsu supports the orderly expansion of existing export enterprises, and strives to cultivate a number of leading enterprises in the import and export of agricultural products to support the development of open agriculture.

  Jiangsu is a province with small per capita resources, but also a province with large processing, trade and consumption of agricultural products. It is urgent to expand new space for agricultural development through open cooperation. In recent years, Jiangsu has given full play to the location advantages of an open economy, seized the opportunity of "One Belt, One Road" construction, adhered to the combination of "going out" and "bringing in", made overall use of two international and domestic markets, two resources and two types of rules, vigorously promoted the structural reform of the agricultural supply side, accelerated the construction of a new pattern of open agricultural development, and expanded agricultural development with a global view, and frequently played "open cards".

  Last year, the total import and export volume of agricultural products in Jiangsu reached 19.66 billion US dollars, of which the export volume exceeded 4 billion US dollars for the first time.

  Cultivate new advantages of open agriculture

  Recently, into the production workshop of Jiangsu Xingye Food Co., Ltd., 12 FD vacuum freeze-drying production lines and 46 AD production ovens are running intensively. The freeze-dried food production workshop covering an area of 20,000 square meters is the largest in Jiangsu. "In order to do a good job in quality control and brand cultivation, we have specially established a raw material planting base of more than 10,000 mu and passed a number of international and domestic quality certifications." Zhang Hongxiao, general manager of Jiangsu Xingye Food Co., Ltd. said that the export volume of dehydrated vegetables of enterprises has remained the first in Jiangsu for many years. From January to May this year, it exported 13 million US dollars, and it is estimated that the annual export will reach more than 25 million US dollars, with an increase of more than 34%.

  "Every two packages of instant noodles have a package of vegetables made in Xinghua." Xinghua city, where Jiangsu Xingye Food Co., Ltd. is located, is the largest production, processing and export base of dehydrated vegetables and the distribution center of finished products in China and even in Asia. Li Weiguo, secretary of Xinghua Municipal Party Committee, said that the city’s dehydrated vegetables, a pillar industry, exported 120 million US dollars last year, accounting for more than 40% of the national and provincial dehydrated vegetables exports.

  "The products of Xinghua dehydrated vegetable industry have developed from a single traditional AD (dried food) product to a series of FD (freeze-dried food) and IQF (quick-frozen food) products. From ingredients to end products, from food accessories to health care products, the types of export products have expanded from the past three varieties of shallots, cabbages and carrots to more than 10 kinds of green peppers, potatoes, sweet potatoes and tomatoes." Li Weiguo said that in recent years, xinghua city has taken the adjustment of agricultural industrial structure as one of the main graspers, focused on attracting talents and attracting investment, and promoted the transformation and upgrading of enterprises. In the next step, xinghua city will make great efforts to promote the health food industry to climb in the direction of intensive processing, terminal food and brand food, and transform from simple product production to design, research and development, brand and service.

  In Jiangsu, despite the rapid development of open agriculture, there are still some problems, such as relatively small total international trade of agricultural products, high land labor costs and obvious restrictions on resource shortage. Therefore, Yang Shiyun, director of Jiangsu Provincial Department of Agriculture and Rural Affairs, said that Jiangsu will make great efforts to adjust the "three structures" and cultivate new advantages of open agriculture. Optimize the export industrial structure, and consolidate and upgrade the characteristic industries around the four export pillar industries; Optimize the structure of high-end products, develop characteristic agricultural products and deeply processed agricultural products, and increase the added value of export agricultural products; Optimize the diversified market structure, seize the opportunity of the "Belt and Road" and jointly develop multi-level agricultural cooperation with relevant countries.

  Using the platform skillfully to expand new achievements

  At the 20th Jiangsu Agricultural International Cooperation Fair held in Lianyungang, Jiangsu Guanyun Huanong Development Company set its sights on the countries related to the Belt and Road Initiative for the first time. Fu Lei, general manager of the company, told the reporter that the Lianyungang Comprehensive Bonded Zone was successfully approved, and the completion of a number of bases and ports, such as the Sino-Kazakhstan (Lianyungang) logistics cooperation base, the first physical project of the "Belt and Road", has built a broad platform for local enterprises to "go global", hoping to push the company’s edible roses abroad and to the "Belt and Road" national market.

  In the process of seizing the opportunity of "One Belt, One Road" construction, Lianyungang actively guides enterprises with comparative advantages to make full use of two resources and two markets, encourages enterprises to invest in foreign countries to build bases and run enterprises, and the agricultural "going out" team continues to grow.

  Peng Renyong, general manager of Lianyungang Yinfeng Edible Fungi Technology Co., Ltd. told the reporter that the enterprise is building a mushroom industrial park in Belarus, and it is expected to produce 900 tons of mushrooms this year. In addition, Jiangsu Yashi Fresh-keeping Products Co., Ltd. built a production and processing base of high-quality agricultural products in Cape Town, Guanyun Samsung Food built a deep processing base of lobster in Egypt, and Lianyungang Guo Xin Company’s edible fungus production equipment was exported to many countries and regions.

  If we want to "go out", we should also "bring in". Suzhou Jinliqi Organic Agriculture Co., Ltd., which is jointly invested by longrich Group and Israeli Aurec Company, is the first to introduce micro-leaf vegetable planting technology in China, and adopt hydroponic soilless planting technology to grow green vegetables and fruits. The annual sales of flour and other products of Yihai Kerry (Kunshan) Food Industry Co., Ltd. invested by Singapore Fengyi International Co., Ltd. reached 2.8 billion yuan, driving more than 5,000 households.

  Platform and carrier are not only the main position of open agriculture, but also the important starting point for agricultural transformation and upgrading driven by open agricultural radiation. At present, there are more than 150 national and provincial open agricultural carriers in Jiangsu, including 131 demonstration bases (districts) for exporting agricultural products, 14 agricultural cooperation parks between Jiangsu and Taiwan, 2 experimental zones for agricultural opening-up cooperation, 3 overseas agricultural cooperation demonstration zones, and 1 scientific and technological support and talent training base for agricultural cooperation with foreign countries.

  Held 20 consecutive provincial "Agricultural Fair" and successfully co-organized the BRICS Agriculture Ministers’ Meeting, China — Major events such as the Ministerial Conference on Agricultural Innovation Cooperation in Israel have promoted a number of major agricultural foreign-funded industrial projects with large investment scale, strong driving force and excellent development quality and efficiency to land in Jiangsu.

  At present, there are 110 agricultural "going out" projects registered and put on record in Jiangsu Province, with an agreed investment of US$ 1.49 billion. Compared with three years ago, both the number of projects and the agreed investment of China have increased by more than 80%. Enterprises from more than 80 countries and regions have invested in Jiangsu agriculture, and 6,624 foreign-invested agricultural projects have been approved, with the actual use of foreign capital of 21 billion US dollars.

  Grasp the point and take the area to build a new pattern

  Not long ago, Jiangsu Province allocated special funds for the development of modern agriculture to cities (counties). The funds were allocated in the form of "big projects+task list" management, which was mainly used to support the transformation and upgrading of open agricultural enterprises, the construction of platform carriers such as agricultural product export demonstration bases (districts), the export of advantageous agricultural products, and the "going out" of agriculture. It was not only clearly listed, but also clearly pointed out that all localities, especially key counties of open agriculture, should improve and perfect the open agriculture-related projects.

  It is understood that special fund policy support is only one of the key points for Jiangsu to support the development of open agriculture. In the future, we will focus on supporting agricultural enterprises and gathering agricultural talents.

  Agricultural products import and export enterprises, agricultural "going out" enterprises and other open subjects are the key to supporting the development of open agriculture and the core to determine the development speed and quality of open agriculture. Jiangsu will support the existing export enterprises to increase capital and shares and expand in an orderly manner, and strive to cultivate a number of leading enterprises in the import and export of agricultural products. Among the 836 leading agricultural enterprises above the provincial level, we will guide enterprises to participate in international trade in an orderly manner and add a number of new export business entities of agricultural products. At the same time, make full use of the Foreign Investment Law and the Special Administrative Measures for Foreign Investment Access (Negative List) (2018 Edition), and vigorously introduce "flagship", "industry leader" and "singles champion" in sub-sectors to invest in Jiangsu agriculture.

  Agricultural talents are the first resource to strengthen agriculture and promote agriculture, and the development of open agriculture cannot be separated from the support of talents. Accelerating the cultivation of open talents is an urgent requirement to win the initiative in the fierce international competition. "Jiangsu takes the cultivation of agricultural talents as an important starting point and focuses on gathering new resources for open agriculture." Yang Shiyun said that Jiangsu adheres to the combination of government support and enterprise self-cultivation, focusing on cultivating practical talents, strengthening the introduction of talents at home and abroad, focusing on gathering high-end talents and scientific and technological talents, striving to cultivate a group of agricultural talents with international vision, and enhancing the development potential of open agriculture in the province.

The car recalled the new rules! It will be implemented on July 1!

Attention all car owners

China’s car recall system has a new regulation!

No longer just because there are security risks or problems.

Automobile exhaust emission will not meet the standard in the future.

Car companies should also recall.

The new regulations will be officially implemented on July 1, 2021.

Make the sky bluer, and cars will be recalled for three emission situations.

In 2020, the number of motor vehicles in China will reach 372 million, including 281 million cars; There are more than 1 million cars in 70 cities across the country. In 2019, the total emission of four pollutants, such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM), was 16.038 million tons. Automobile is the main contributor to the air pollution emission of motor vehicles, and its emission of CO, HC, NOx and PM exceeds 90%.

In order to reduce emission pollution, the General Administration of Market Supervision and the Ministry of Ecology and Environment recently formulated and issued the Regulations on the Management of Motor Vehicle Emission Recall (hereinafter referred to as the Regulations), which extended the product recall from safety recall to emission recall.

Automobile safety recall system has been implemented for a long time, and everyone is familiar with it, but emission recall is still a new thing. Under what circumstances will motor vehicles be recalled because of emissions?

The "Regulations" give three specific situations:

1. Air pollutants emitted by motor vehicles exceed the standard due to design and production defects;

Second, because it does not meet the specified requirements for environmental protection durability, the air pollutants emitted by motor vehicles exceed the standard;

Third, due to design and production reasons, there are other motor vehicles that do not meet emission standards or unreasonable emissions.

The emission standards involved in the Regulations mainly include GB18352.6-2016 Pollutant Emission Limits and Measurement Methods for Light Vehicles and GB17691-2018 Pollutant Emission Limits and Measurement Methods for Heavy Diesel Vehicles, all of which are the sixth-stage motor vehicle emission standards in China (referred to as "National Six Emission Standards").

The biggest impact on consumers is mainly the emission standards of light vehicles.

According to the requirements, from July 1, 2020, all light vehicles sold and registered should meet the national six emission standards; Before July 1, 2025, the "in-service compliance inspection" of light vehicles in the fifth stage will still implement the relevant requirements of GB18352.5-2013.

The "Regulations" adopt the principle of "old standards for old cars and new standards for new cars" when implementing emission standards, which is in line with legal requirements and management practice.

The "unreasonable discharge situation" mentioned in the third case of the above recall mainly refers to the illegal discharge of air pollutants tested by motor vehicles under standard working conditions that meet the standard limit, but the pollutant discharge exceeds the standard limit under actual working conditions.

For example, in 2015, Volkswagen in Germany installed illegal software in its cars and deliberately evaded the US automobile exhaust emission regulations. The actual pollutant emission of vehicles exceeded the legal standard by 40 times, and it was fined by the United States by 4.3 billion US dollars, involving 11 million motor vehicles.

Motor vehicle storage and emission hazards,

Car companies and parts factories will be investigated.

Article 14 of the Regulations points out that if the Ministry of Ecology and Environment finds that motor vehicles may have emission hazards during the supervision and inspection of air pollution prevention and control, the General Administration of Market Supervision and the Ministry of Ecology and Environment may investigate the motor vehicle producers and, if necessary, the producers of emission parts.

The "Regulations" strengthen the implementation of legal responsibilities, and clarify that motor vehicle producers or operators who violate the relevant obligations of the "Regulations" will be "ordered by the market supervision and management department to make corrections and be fined up to 30,000 yuan". Compared with the penalty requirements of safety recall, the prerequisite of "overdue correction" is removed, which improves the authority and compulsion of the Regulations and is conducive to improving the effectiveness of recall supervision.

At the same time, the "Regulations" stipulate that the recall and administrative punishment information will be included in the credit file and announced to the public according to law. This clause is directly related to the brand image and credibility of producers, with the purpose of enhancing the awareness of quality and integrity of enterprises, and to some extent, it can make up for the shortage of the "Regulations" as a departmental regulation, and urge enterprises to actively fulfill their recall obligations.

Will the emission recall affect the development of China automobile industry?

In 2020, China’s automobile sales will continue to rank first in the world. The profit of the automobile manufacturing industry increased by 4.0%.

Some people worry that the automobile industry is an important pillar industry of China’s national economy, and will the emission recall hinder the development of this industry?

However, in the opinion of experts, emission recall is the general trend, and there is no need to be too afraid or exaggerate its impact.

"In the short term, the cost of bicycle recall may be higher than that of automobile safety recall, which will bring greater economic and brand pressure to some enterprises with low emission technology in the short term. However, in the long run, the Regulations will encourage the motor vehicle industry to pay more attention to the research and development of emission technologies and related standards, and force enterprises to take the initiative to upgrade their technologies. "

For example, motor vehicle enterprises should strengthen research and development and testing related to emissions and produce motor vehicle products that meet relevant national emission standards; Emission parts manufacturers should take the initiative to innovate and develop emission parts products with high performance and reliability.

"The implementation of emission recall is an inevitable trend. Only by actively benchmarking the gap and strengthening innovation can enterprises change from price advantage to comprehensive competitive advantage with technology, brand, quality and service as the core, and achieve high-quality industrial development." Experts say that the recall of motor vehicle environmental protection is one of the important means to prevent and control motor vehicle emission pollution, which is also confirmed by relevant international practices.

China has taken the first step in the journey of 5G "space communication"

The 5G era has kicked off

However, the coverage of the global network still faces great challenges.

It is difficult for ground base stations to cover desert, ocean and other areas.

Low orbit broadband communication satellite can solve the problem of global network coverage and access.

Scenes such as brushing short videos and making video calls on the plane.

Will become a future within reach.

The "online celebrity" rocket that was screened by the track cloud.

Kuaizhou-1A carrier rocket

It is the first launch vehicle in China’s fast boat series to be put on the market.

Japan’s new goddess is actually the Prime Minister’s bodyguard: it takes only 0.2 seconds to kill the enemy by taking down 10 strong men with bare hands.

Original Weekly Authors Group World Chinese Weekly

A woman with extraordinary courage and perseverance.

Author: Hua Ci Shu

Japan’s new otaku goddess Ishida Mengmei has a high popularity.

She looks sweet and looks just like Yoko Maki, the heroine in the Japanese movie Bodyguard, and soon became popular all over Japan.

▲ Yoko Maki

And her true identity is a big surprise. Not online celebrity, not an idol, but bodyguards of two former Japanese prime ministers.

Once, the picture of Ishida Mengmei performing security tasks beside Shinzo Abe was posted online. The speed of the red is overwhelming.

Many keyboard men don’t believe her true ability at all. Can such a weak girl undertake the high-load security work of the Prime Minister?

This is also a question that many people are deeply puzzled when they first see her.

As a beautiful female bodyguard, can she do it?

Open the resume of Shimoda Mengmei, and anyone will sweep away prejudice and admire her perseverance and persistence.

She is a top kung fu master in Japan, with many certificates such as kendo, karate, judo and fighting. She can pull out her gun and shoot thugs in 0.2 seconds and kill robbers in 0.5 seconds.

Set a karate record, once defeated 10 karate brawny men in a row, and even kicked over the beast with one volley. The force value can suppress half of male colleagues in the Metropolitan Police Department.

With such a beautiful record, it is no wonder that Noda Yoshihiko and Shinzo Abe have a lot of trust in her, and they will take them with them when they visit.

The enlightenment education of Ishida Mengmei is already different from other children. Little girls of the same age learn piano, ballet and painting, taking the route of quiet little princess.

Ishida, on the other hand, was sent to a judo enlightenment institution by her parents. The training was hard, and the difficulty required by the coach was increasing day by day. The girls in the class withdrew one by one, but only she persisted.

No matter how tired and bitter she is, she never cries. Because of her family background as a bodyguard, her father was very strict with her, and she often made surprise assessments to test her daughter’s learning achievements in the judo hall.

Worried that he couldn’t pass his father’s exam, Ishida still volunteered to strengthen training after class. Later, at a young age, Ishida Mengmei was not to be underestimated in judo.

At the same time, she also learned kendo, karate, and even mysterious endurance. The most difficult thing is to practice kendo. At that time, she was still young, and she could barely pick it up by holding wood blade with both hands.

In the harsh education of parents, the tough side of Ishida’s beauty is also displayed. She didn’t cry to anyone to give up, but practiced harder and made up for her lack of strength with skilled skills.

And until adulthood, Kendo was always a training project that Ishida insisted on. At the age of 18, she easily achieved the third stage of Kendo.

This also means that she has reached a new stage in physical strength, skills and mentality, and can be said to be a real yogi standing at the entrance of kendo.

After training day after day, Mengmei Ishida gradually became a master of all kinds of kungfu, and her parents finally assured her to go out and wander.

Surprisingly, however, in the face of numerous occupations, she chose to inherit the family business and become a bodyguard.

Although my father is a well-known bodyguard in Japan, he trains his daughter in martial arts just to keep her fit and protect herself at critical moments.

Once Ishida stepped into the bodyguard industry, he would live in a latent crisis every day, and he was familiar with such days.

Faced with the dissuasion of her family, Mengmei Ishida thought twice and decided to be a bodyguard. Like her father, she wants to be able to go in and out of important occasions and escort political dignitaries.

Besides, being able to appear as a female bodyguard made her more excited.

In 2011, 23-year-old Mengmei Ishida opened the door of the Security Department of Tokyo Metropolitan Police Department with professional certificates in various fighting fields.

Not long after, she entered the "Japanese Presidential Guard" through layer-by-layer selection and officially became the personal bodyguard of former Prime Minister Noda Yoshihiko.

Being elected as a presidential bodyguard in his early twenties is extremely rare even among men, and Ishida is called "the best of the elite".

In Japan, if you want to be a member of the Presidential Guard and perform security tasks beside the Prime Minister, it is simply more difficult to select and assess.

First of all, the height of female bodyguards should be higher than 1.6 meters, and the level of karate and kendo should reach at least level 3.

Secondly, to be proficient in all kinds of firearms, you must have the shooting level of piercing Yang with a hundred paces. It is said that bodyguards are required to shoot five times in 20 seconds, which is less than 10 cm away from 25 meters.

In addition, we should be proficient in English, and have a strong sense of responsibility and self-sacrifice spirit.

These can’t beat Mengmei Ishida, who is tall and proficient in all kinds of fighting skills, and even became famous in the first world war because of her extraordinary skills.

Complete the process of drawing a gun and shooting in 0.2 seconds, and the action is flowing and fast.

Without guns, with the help of karate, ten karate strong men were taken down by one to ten. This kind of bloody bridge is like a TV series.

In addition, Ishida Mengmei also has a trick to kill, called "give my life to kick." By her volley kick, even a man who is three times taller and stronger than her will fall to the ground.

Because of her outstanding appearance, Mengmei Ishida has attracted much attention in the Metropolitan Police Department. After learning that she is still stunted, many colleagues are discouraged from beauty.

Of course, this kind of contrast has aroused the love of many Japanese otaku, who enthusiastically follow Shimoda’s beauty and call her "a thorny rose" in worship.

With real kung fu, Mengmei Ishida became famous in the Japanese bodyguard industry. Not only did he become the personal bodyguard of former Japanese Prime Minister Noda Yoshihiko, but even Shinzo Abe, who later took over, also pointed out that she should be "escorted".

She used strength to prove that people who can eat by beauty must have strength to go far.

As a professional bodyguard, Mengmei Ishida wears a wide suit with holsters, pistols and wireless communication devices at work all year round.

In addition, the expression should be fierce, and the eyes should be murderous. Only by emitting a strong gas field can the terrorist attack be shocked as much as possible.

There are still many female bodyguards like Mengmei Ishida in Japan. In addition to the presidential guard where she works, there is also a special security special police team composed of female bodyguards in Japan.

The initial formation opportunity can be traced back to the visit of the Queen of England and Margaret Thatcher to Japan. At that time, in order to facilitate the travel of female leaders, the Japanese government specially replaced the personal security personnel with women.

It also proves that professional female bodyguards are not inferior to traditional male bodyguards, and even more reliable.

Many examples show that male bodyguards often go out to drink during their vacation, which leads to the inability to return to the team immediately for emergency tasks, while the probability of such a situation for female bodyguards is extremely low.

And female bodyguards can also serve as secretaries, nannies and other careful work, which can not only take care of daily life, but also provide security in a hidden way, killing two birds with one stone.

By the end of Thatcher’s visit, this Japanese female security swat team had been preserved.

When holding a diplomatic conference in Japan, it provides security for female leaders and first ladies of various countries.

Not only in Japan, but also in countries all over the world, female bodyguards are gradually emerging around leaders. For example, Wendy Basnan, the female bodyguard of former US President George W. Bush, attended the Beijing Olympic Games.

In addition, these female bodyguards are brave and fearless in the face of danger, which has repeatedly proved that bodyguards are not just a male-only profession.

Anna loginova, the most famous Russian female bodyguard, is not only a top supermodel, but also an idol of the younger generation in Europe and America.

▲ anna loginova

Male bodyguards are forbidden to enter in many high-end places in Moscow, and Anna, accompanied by a female companion, secretly provides protection for countless celebrities.

Reputation and crisis coexist, and she has been caught in critical emergencies for many times, and she has survived again and again, which makes Anna’s security quality always well-known.

Unfortunately, however, she was dragged 800 meters by a car in a fight with a robber, and she was only 29 years old when she died. After learning the bad news, customers in the past collectively mourned and came forward to ask the police to trace the murderer.

It can be seen that a female bodyguard can also be remembered by people for her superb martial arts and excellent professionalism.

In addition, in the turbulent period, once the female bodyguards around the leaders are captured, the inhuman torture suffered is even more unimaginable.

A scholar dies as a confidant, and a woman is a lover of herself. Nowadays, women can also die for their dreams.

Who can say that security tasks are exclusively for men?

Over the years, many occupations that used to be exclusive to men are being broken by women’s courage and ability, and the barriers between gender and occupation are gradually loosening. We should also bid farewell to those stereotypes.

Only boys are good at science, and girls had better study liberal arts.

When a girl goes to middle school, she will be distracted and not study hard.

Girls should stay out of what men should do.

Similarly, every woman will hear it more or less when she grows up, but gender is not an excuse to kill her ability.

For example, Mengmei Ishida is the top "killer" in Japan. She is loyal to her career and has completed the security task with a high sense of responsibility and top business ability.

Therefore, she has been highly praised by the Japanese people: she is a woman with extraordinary courage and perseverance.

And she also has a lovely side, she will go shopping in private, love to dress up and take selfies of MengMeng.

In her, professionalism and female personality coexist peacefully. Ishida faced more and more criticisms and praises, but her attitude was consistent.

"I don’t care what the outside world thinks of me. My duty is to protect the Prime Minister, that’s all."

Women hold up half the sky, this sentence is not just talk.

The world is colorful because of gender differences. When more female bodyguards like Mengmei Ishida emerge, it is a different kind of brilliance in itself.

It also reminds us of that sentence again: Girls can do everything!

  Spontaneous combustion in the cabin of charging treasure

  On the morning of September 4th, a number of netizens said that there was an open fire in the cabin of flight MU2809 of China Eastern Airlines and it returned to Nanjing. The video shows that the cabin of the plane is shrouded in smoke, and there are flight attendants in a seat, which is suspected to be being disposed of at the fire. In another photo taken by netizens, it can be seen that the inner wall of a window in the cabin has been burned and the cabin wall has been blackened.

  According to the flight information, flight MU2809 of China Eastern Airlines took off from Nanjing Lukou International Airport at 7: 16 a.m. It was originally scheduled to arrive at Xiamen Gaoqi International Airport two hours later, but it returned to Nanjing Lukou International Airport at 8: 24.

  remove doubts

  Take a charging treasure to fly.

  What are the specific regulations of airlines?

  According to ICAO’s Technical Rules for Safe Air Transport of Dangerous Goods and China’s Regulations on the Administration of Civil Aviation Transport of Dangerous Goods, passengers should abide by the following provisions when carrying charging treasure: charging treasure must be carried by passengers for their own use, and charging treasure can only be carried in hand luggage or carried with them, and it is strictly prohibited to carry it in checked baggage. The rated energy of the charging treasure carried by passengers does not exceed 100Wh (watt hour, 100Wh equals 20,000 mA), without the approval of airlines; The rated energy exceeds 100Wh but not more than 160Wh, which can only be carried with the approval of the airline, but each passenger is not allowed to carry more than two charging treasures. It is strictly forbidden to carry charging treasures with rated energy exceeding 160Wh; It is strictly forbidden to carry charging treasures that are not marked with rated energy and fail to calculate the rated energy through other marked parameters. Passengers are not allowed to use the charging treasure to charge electronic equipment during the flight. For the charging treasure with the start switch, always turn off the charging treasure during the flight.

  According to the safety officer of an airline in China, it is forbidden to use the charging treasure to charge the mobile phone during the whole flight. If the passenger insists on using the charging treasure and the warning from the safety officer is invalid, the safety officer will take compulsory measures to stop the passenger from using the charging treasure and notify the public security organ to deal with it.

  survey

  The quality is mixed

  The quality of Shanzhai charging treasure is difficult to guarantee.

  Previously, the Beijing Youth Daily reporter had found that the prices of charging treasures in the market were different, ranging from a dozen yuan to hundreds of yuan. On the online shopping platform, shanzhai and Sanwu charging treasures have sold more than regular manufacturers’ products because of their low prices. The reporter of Beiqing Daily found that the electronic circuit boards of Shanzhai and Sanwu products were simple, the workmanship was rough, and even the "cement battery" was used to charge them, and the parts were shoddy and the liquid in the battery leaked.

  The charging treasure produced by regular manufacturers is difficult to disassemble, and the disassembled electronic circuit board is relatively complicated. The components and batteries used are marked with serial numbers, and each component is wrapped with flame retardant materials.

  It is reported that in 2015, Jiangxi destroyed a fake charging treasure den, and the seized cottage charging treasure contained six batteries, four of which were fakes filled with cement.

  Relevant persons engaged in lithium battery research said that most of the circuit boards of brand charging treasures currently on the market have devices such as overcharge protection and overdischarge protection. In order to save costs, most of the batteries are made by small workshops, and the electronic circuit boards are connected by themselves. The safety cannot be guaranteed and it is very easy to cause fires.

  News memory

  Charging treasure happens many times.

  Smoke or fire incident

  It is reported that in February 2017, on the Spring Airlines flight from Harbin to Nagoya, a charging treasure carried by a passenger suddenly spontaneously ignited and caught fire, and the flight was diverted to Shenyang Taoxian Airport, causing no injuries.

  In July 2017, during the taxiing process of China Southern Airlines flight from Beijing to Hangzhou, a passenger’s charging treasure spontaneously ignited, resulting in a flight delay of two hours. After on-site inspection by the security department, the passengers on this flight passed the security inspection, and the output voltage of the charging treasure they carried was 5V, and the calculated rated energy was 50Wh, which was clearly marked and met the civil aviation transportation standards.

  In February 2018, on flight CZ3539 from Guangzhou to Shanghai, the charging treasure carried by passengers on the luggage rack caught fire when passengers were boarding. At that time, after the crew cooperated with the fire and public security departments to deal with it in time, no further damage was caused. The flight was changed and the crew was executed, and the passengers involved were taken away by the police for investigation.

  In August, 2018, during the security check at Zhengzhou Airport, the passenger Kong Mou was told by the security inspector that the charging treasure he was carrying did not meet the relevant regulations and could not be carried. In a rage, Kong Mou smashed the charging treasure on the floor, causing the charging treasure to spontaneously ignite, causing smoke at the scene, which was promptly disposed of by Zhengzhou airport scanner without causing personal injury. Subsequently, Kong was placed in administrative detention.

  In July 2019, Chiang Mai Airport in Thailand released a video of the charging treasure in the passenger bag catching fire inexplicably.
