[News] With the gradual opening of road test, can autonomous driving be far behind? Not long ago, the country issued the specifications of road test related to intelligent driving, and Shanghai, Fujian, Chongqing, Shenzhen, Changchun, Changsha and other places have also issued relevant road test rules one after another, but only Beijing, Shanghai and Chongqing issued the number plate for road test. Among them, Shanghai was the earliest. On March 1 this year, Shanghai issued a road test number plate to SAIC. Chongqing has the most. On April 18th, Chongqing issued license plates to seven companies: Baidu, Guangzhou Automobile, Geely and Beiqi. Beijing’s latest, during the auto show, Beijing just announced that Weilai won the number plate (Beijing had previously issued a number plate to Baidu). Taking advantage of the east wind, let’s take a look at the progress of these car companies that have obtained number plates in the field of intelligent driving.

Beiqi New Energy: Releasing "Darwin System"

　　BAIC New Energy, which just got the number plate, released the vehicle artificial intelligence system "Darwin" at this auto show. British biologist Darwin’s theory of evolution has a basic view: evolution has no direction and no end. Correspondingly, the Darwin system can also realize continuous self-learning and growth. In the future, BAIC New Energy will carry up to 546 chips on a bicycle to handle data requirements, and upgrade the OTA (over-the-air program) of the whole vehicle.

　　As the pioneering work of "Darwin System", BAIC new energy EU5 was officially listed at Beijing Auto Show. The vehicle model integrates 10 intelligent driving assistance devices and technologies, including lane departure warning, pedestrian collision warning, vehicle collision warning, automatic emergency braking and other auxiliary driving technologies. With EMD 3.0 intelligent electric drive technology, it can accurately monitor driving safety and correct the path in real time.

　　BAIC New Energy mainly cooperates with Baidu, Bosch and Harman in the field of automatic driving to realize the research and development of intelligent driving functions including ADAS intelligent assisted driving system, L3 automatic driving, intelligent cockpit monitoring and parking service. Among them, the intelligent cockpit system with multiple application scenarios will be fully equipped on the models listed in 2018-2020.

　　The road to autonomous driving BAIC New Energy will also rely on the strength of BAIC Group. According to the plan, BAIC Group’s vehicles will be Baidu’s open platform, and L3 self-driving vehicles will be mass-produced around 2019, and L4 self-driving vehicles will be mass-produced around 2021. The driverless plan of BAIC New Energy may also be promoted according to this.

Weilai: the only car company that got the number plates of two places.

　　Consistent with the new energy qualification review, the choice of intelligent driving license plate is also more inclined to traditional car companies at present. Among the eight car companies that have obtained road test license plates in various provinces and cities, only Weilai Automobile is a new car company, and it is also the only passenger car company that has obtained license plates in Beijing and Shanghai.

　　At this auto show, Weilai booth was particularly popular. Apart from the car itself, the on-board artificial intelligence system "NOMI" is also eye-catching. Based on the powerful on-board computing capability and cloud computing platform, it integrates a voice interaction system and an intelligent emotion engine, which can talk with people, automatically adjust the temperature inside the car, automatically purify the air inside the car, and help car owners take selfies.

　　As an emerging car company, Weilai has been committed to intelligent driving research and development. In the ES8, the first model of Weilai released at the end of 2017, the automatic assisted driving system NIO was equipped. In the scheme of perception system, there is a three-eye camera, four panoramic cameras, five millimeter-wave radars, 12 ultrasonic sensors and a driving state detection camera. It can achieve more than 20 core capabilities such as adaptive cruise, high-speed automatic assisted driving, congestion automatic driving, automatic road maintenance, parking assistance, automatic parking, active vehicle call and fatigue warning.

　　Weilai mainly cooperates with leye, NVIDIA and NXP in the field of intelligent driving. At present, a large number of automatic driving function tests have been completed, including simulation tests and closed road tests. At the same time, Weilai launched the open road test plan in California, Beijing, China and Shanghai. According to the plan, Weilai will release vehicles with L4-level automatic driving capability in 2020.

Saic: zebra intelligent system welcomes version 3.0.

　　As a car company that proposed "Internet car" earlier, on the eve of this auto show, the Marvel X, a brand-new pure electric vehicle of SAIC, officially made its debut. It is reported that the car is equipped with AR augmented reality technology, version 3.0 Internet car zebra intelligent system, all-round intelligent welcome system, as well as wireless charging, automatic parking and parking functions.

　　SAIC has a long history in the field of intelligent driving. When it was launched in 2015, it already had intelligent driving assistance function. When the speed is 60-120 kilometers per hour, it can realize automatic cruising, automatic car following, lane keeping, lane changing and autonomous overtaking. In the field of new energy, both Roewe ERX5 and Roewe ERX 5 are equipped with zebra Zhixing system, which can realize the above intelligent driving assistance function. Not long before the auto show, SAIC announced that the upgrade of Zebra Zhixing System 2.0 on Roewe ERX5 will be started, and users can enjoy the OTA upgrade service for free. At that time, users will receive download prompts and updates, including maps, voice and HMI. All interfaces will be updated.

　　In the field of intelligence, SAIC mainly cooperates with Ali. As early as July 2014, the two sides signed a strategic cooperation agreement and formally established Zebra Zhixing Company, which is committed to providing the overall solution of Internet vehicles for the entire automobile industry. At present, it has been applied to a number of SAIC models. At the same time, SAIC also obtained California’s autopilot test license in 2017 to conduct autopilot road test work in the United States.

Chang ‘an: L2 technology will be launched.

　　Since the "Shangri-La" plan was released last year, Changan Automobile has made frequent moves in the fields of electrification and intelligence. At this auto show, Changan presented a new generation of CS75, which is equipped with Changan APA4.0 parking service system, which can realize the functions of active parking search, one-button parking inside the car, remote parking outside the car, etc. In addition, Foreign Minister Anxin CS75 is also equipped with Bosch’s new generation AEB early warning auxiliary braking, LCDA intelligence, LDW lane departure warning and many other intelligent driving assistance functions.

　　At the same time, the CS55-IACC version of Changan Automobile will be launched soon, which is equipped with IACC integrated adaptive cruise technology and has reached the L2 level of automatic driving. IACC adopts multi-sensor integration technology, integrates millimeter-wave radar, multi-function camera and navigation map, perceives the driving road environment, and controls the automatic acceleration, deceleration and steering of the vehicle through power, braking and steering, so as to keep the vehicle in the lane or follow the track of the target vehicle in front.

　　The driverless test of Changan Automobile started two years ago. As early as 2016, Changan driverless car arrived in Beijing safely from Chongqing in five days and completed the 2000km driverless test; In November 2017, Changan Automobile obtained the California road test driverless car test license.

　　In the field of autonomous driving, Changan Automobile currently mainly adopts the form of cooperation with other enterprises, and has signed contracts with many enterprises such as Weilai, Baidu, Intel, Alibaba and Tencent. But at the same time, Changan is also doing independent research and development, which will be gradually applied when the technology is mature.

FAW: At present, no action has been implemented in the field of automatic driving.

　　Among many license plate car companies, the specific implementation of FAW’s automatic driving in the passenger car field is the most mysterious. At the auto show, FAW exhibited FAW, and the official pointed out that its main theme is "Yan value+intelligence" and it will be listed in 2018. But so far, no further details about the field of intelligent driving have been released, except that the car is equipped with 4G network and has HMI platform.

　　As early as April 2015, FAW Group released a complete intelligent interconnection strategy-"Zhitu". According to the plan, by 2020, FAW will gradually carry L3-class automatic driving on a series of products in terms of intelligence; In terms of informatization, combined with the comprehensive application of 5G, a perfect V2X system is established to improve driving safety and traffic efficiency. By 2025, FAW will realize the serialization of L4 self-driving products in terms of intelligence; In terms of informationization, based on the big data of the Internet of Things, we will integrate social travel resources and establish a high-quality mobile travel service ecosystem.

　　In the field of intelligent driving, FAW chose Tencent as its small partner. In April this year, Tencent and FAW formally signed a strategic cooperation framework agreement, and the two sides will build intelligent networked products based on Tencent Car’s "AI in Car" intelligent solution.

Dongfeng: Launching Link3.0 System

　　During the Beijing Auto Show, the eπ concept car, a new energy concept, was launched on the Dongfeng booth. It can obtain the optimal path planning, provide remote medical treatment, interact with family members in real time, assist users to pay attention to hot spots along the way in real time, and provide real-time travel with real-time interconnection positioning and automatic greeting technology between cars and people.

　　In addition to the vehicle model display, it also brought the WindLink3.0 artificial intelligence vehicle system display, which was jointly built by dongfeng fengshen, Baidu and Botai, and realized the functions of one-button navigation, one-button positioning, peripheral search, interest point search, off-line navigation and so on through voice interaction. In addition, it can remotely control the doors, windows, air conditioners and so on through the mobile App, and monitor the vehicle condition in real time. This system will be carried on passenger cars in dongfeng fengshen which will be launched this year, and will cover all product series in the next three years.

　　Dongfeng’s layout in the field of intelligent driving has been started since 2013, and it has been technically equipped on mass-produced vehicles in dongfeng fengshen. It has successively launched A60 intelligent prototype in 2013, AX7 intelligent prototype 1.0 in 2014 and AX7 intelligent driving prototype 2.0 in 2017, and completed the engineering and industrialization of new technologies such as automatic parking and intelligent assisted driving. In the field of driverless driving, Dongfeng plans to mass-produce driverless cars by 2020, but it will be used in special fields and commercial fields first.

Guangzhou Automobile Co., Ltd.: In 2019, L4-class autopilot demonstration operation will be realized.

　　Guangzhou Automobile mainly focuses on new energy in the field of intelligent driving. At this auto show, the first new energy concept car developed for the North American market was released. Although Guangzhou Automobile did not describe this model in the field of automatic driving, its window did not choose traditional glass material, but it can be integrated with the door when it is closed, which means that the window is opaque and the car can’t be seen outside, so it is judged that the main control mode designed for the Enverge concept car is automatic driving.

　　GAC mainly cooperates with Huawei, Tencent, Ali, Cisco China and Didi Chuxing in the field of autonomous driving, and will cooperate in the fields of cloud computing, car networking, intelligent driving, new energy vehicles, big data applications and travel services. According to GAC’s new energy plan, the future is not only to launch new energy vehicles, but more importantly, smart cars. The company plans to realize the demonstration operation of L4-level highly automatic driving in 2019, and gradually upgrade to L5-level fully automatic driving.

Geely: mainly relying on its own strength for research and development.

　　At the Beijing Auto Show in 2018, Geely brought GKUI in-vehicle system, which is a deeply customized in-vehicle system based on Android system, and supports many functions such as car networking, car-machine interconnection, navigation, multimedia, third-party App, etc. The system has been used in Geely’s various models.

　　The use of the above functions is still in the state of car networking. Geely has not yet equipped with intelligent driving including related auxiliary functions, but it has technical reserves. At present, the models on sale have relied on ACC adaptive cruise system and completed the initial prototype of automatic driving. Starting this year, Geely’s models will be equipped with car networking technology, and intelligent driving assistance functions such as automatic parking will be carried one after another.

　　Different from other experts, Geely’s autonomous driving field, like the Internet of Vehicles, mainly relies on its own strength for software and hardware development. It is reported that there are currently 600 teams for hardware development and 400 teams for software development. According to Geely’s plan, it is predicted that L3 system with high automatic driving ability will be realized in 2020, and L4 system with fully intelligent automatic driving will be realized in 2024.

Full text summary:

　　Undoubtedly, intelligent driving must be the future direction. According to the feedback from car companies, more and more vehicles equipped with intelligent driving assistance functions will be launched in the next year or two, mostly with L2 level. At the user level, the biggest experience lies in voice recognition, automatic parking, etc. Most cars with L3/L4 level tend to appear around 2025, while the higher L5 level is still far away from the legal level and car company planning for the time being. But in the long run, multi-screen, driverless, and canceling the steering wheel are the future trends. In addition, from the perspective of cost, according to car companies, with the improvement of automatic driving level in the short term, the cost is still rising, but after reaching an order of magnitude, the cost will decline.

"double 11" hasn’t arrived yet, and the smell of smoke among merchants has started.

On October 26th, Suning held the kick-off meeting of "double 11 National Carnival" in Nanjing. Hou Enlong, president of Suning.cn, said in his speech that the number of stores in Suning will exceed 10,000 in double 11 this year.

Hou Enlong said that the energy of these 10,000 stores far exceeds that of 1 million ordinary stores, and each store in Suning includes various functions such as goods, services and experiences to achieve refined operation.

"We have actually opened 10,000 Internet stores, and now many people in the industry can do 600,000 or 1 million with a wave of their hands. I think it is more on paper." Hou Enlong said, "Like the pig on the tuyere, it will fall and die sooner or later. This simple use of data to make traffic go offline is untenable. "

Hou Enlong’s statement was interpreted as challenging his opponent JD.COM. Liu Qiangdong, the founder of JD.COM, announced in 2017 that more than 1 million JD.COM convenience stores will be opened nationwide in the next five years, with the opening rate of 1,000 stores every week.

It’s not the first time that Hou Enlong, president of Suning.cn, "choked" Liu Qiangdong.

At an event in July, 2018, the host asked questions about JD.COM’s advantages over Ali. Liu Qiangdong replied that JD.COM paid attention to the user experience and only sold genuine products. The host who asked questions gave a "hehehehehehehehehe" laugh. The next day, Hou Enlong released the Weibo, posting six words: "Hehehehehehehehehe", accompanied by a Pinocchio with a long nose in the cartoon Pinocchio.

This year’s "double 11", Suning’s carnival activities will last for 12 days, and the slogan shouted is "Go to the streets and go to Suning". Among them, November 9th is the "Super Store Day", and the offline stores (Su Xiansheng, Suning Store, Suning Plaza, Suning Red Kids, Suning.cn) will deliver it in 30 minutes at the earliest, and pay for it in one hour. Offline stores will also actively push red envelopes for users within 3 kilometers.

In addition, Suning is still promoting offline services. On October 20 this year, Suning opened the first Hakka-helping shop in Nanjing, providing various services needed by life, such as household appliances cleaning, housekeeping cleaning, laundry, home improvement, etc. Consumers in the surrounding area of 3 to 5 kilometers can enjoy the "321" service standard created by helping Hakka, that is, 3 minutes response, 2 hours door-to-door service and 1 hour service completion. At the press conference, Suning also announced that Suning Automobile officially launched the O2O service system. After purchasing the aftermarket products, consumers can directly enjoy the installation and maintenance services offline. At present, the first batch of offline outlets that have settled in Suning Automobile O2O service system have reached 28,000.

It is worth mentioning that on the eve of "double 11" this year, some express delivery companies, including Zhongtong and Yuantong, have announced price increases and allocated parts fees. At the kick-off meeting of Suning Carnival on October 26, Suning announced that from November 1 to 11, Suning’s self-operated products will be free of freight, and consumers don’t have to make up for free freight.

When talking about why the freight rate is not increased, Hou Enlong explained: "First, we are a retail enterprise, not a courier company. It is very immoral for you to be a retail enterprise to increase the freight rate, because you are a retailer and you are not a courier. This is the first. Second, you let all the poor people not come to you. You are doing the rich economy, and you are guilty of pink eye. "

In addition, after Alipay’s "koi fish" campaign became popular, Suning also decided to launch similar marketing measures. From November 1 to 11, Suning.cn will select a "transit lion" every day, and more than 100 brands will contract its consumption demand for one year.

(Information disclosure form: voluntary disclosure)

The second dose of Covid-19 vaccine was used to boost immunization.Inoculation implementation plan

In order to thoroughly implement the decision-making arrangements of the CPC Central Committee and the State Council, further improve the response to the COVID-19 epidemic, and ensure people’s life safety and health, through research, we now put forward the implementation plan of the second dose of Covid-19 vaccine to strengthen immunization.

First, the target population

At this stage, on the basis of the first dose of booster immunization, the second dose of booster immunization can be carried out among people with high risk of infection, people over 60 years old, people with serious basic diseases and people with low immunity.

Second, vaccine selection and time interval

(1) vaccine selection.According to the progress of vaccine research and development, all vaccines approved for conditional marketing or emergency use can be used for the second dose of booster immunization. Priority is given to sequential booster immunization, or the second dose of booster immunization with vaccines containing Omicron strain or with good cross-immunity to Omicron strain. The relevant combinations are as follows:

3 doses of inactivated vaccine +1 dose of Kangxinuo intramuscular recombinant Covid-19 vaccine (adenovirus type 5 vector);

3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (CHO cells) of Chifeilongkema;

3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (adenovirus type 5 vector) for Kangxinuo inhalation;

3 doses of inactivated vaccine +1 dose of Zhuhai Livzon recombinant Covid-19 fusion protein (CHO cell) vaccine;

2 doses of Kangxinuo intramuscular adenovirus vector vaccine +1 dose of Kangxinuo inhalation recombinant Covid-19 vaccine (adenovirus vector type 5);

3 doses of inactivated vaccine +1 dose of Chengdu WEEK recombinant Covid-19 vaccine (sf9 cells);

3 doses of inactivated vaccine +1 dose of Beijing Wan Tai nasal spray influenza virus carrier Covid-19 vaccine;

3 doses of inactivated vaccine +1 dose of Zhejiang clover recombinant Covid-19 protein subunit vaccine (CHO cells);

3 doses of inactivated vaccine +1 dose of recombinant Covid-19 bivalent S trimer protein vaccine from Shenzhou cells.

(2) Time interval.According to the real world research and clinical trial data at home and abroad, combined with the actual vaccination in China, the time interval between the second dose of booster immunization and the first dose of booster immunization is more than 6 months.

Third, ensure vaccination safety

All localities should continue to give priority to vaccination safety, and organize vaccination implementation in strict accordance with the requirements of the Code for Vaccination Work. Local health departments should implement the "four haves" requirement that vaccination units should have emergency personnel stationed in general hospitals at or above the second level, emergency equipment and medicines, 120 ambulances on duty, and green channels for treatment in general hospitals at or above the second level to ensure vaccination safety. Inoculation units should do a good job in strengthening the vaccination information registration and vaccine flow management, and update the vaccination records in the immunization planning information system and vaccination vouchers in a timely and accurate manner.

Fourth, strengthen organization and implementation

(1) Strengthening the responsibility of territorial subjects.All localities should implement the responsibility of territorial management, attach great importance to and co-ordinate the vaccination work in Covid-19. It is necessary to strengthen the guidance of vaccination work within the jurisdiction and fully grasp the progress of the work. Relevant local departments should strengthen docking and do a good job of coordination.

(two) the implementation of departmental industry management responsibilities.The competent departments of relevant industries should guide the units where the personnel in this industry work to actively cooperate with local unified arrangements and jointly do a good job in organizing and mobilizing.

(3) Strengthen supervision and guidance.It is necessary to closely track and monitor the progress of the second dose of enhanced immunization in various places, and find and study and solve related problems in time. Improve the traceability system of vaccine flow, improve the safety supervision mechanism of vaccine whole chain, and continuously strengthen the whole process management and safety prevention.

(4) Do a good job in publicity and guidance.All localities and relevant departments should, according to the needs of the work, formulate targeted publicity measures to strengthen the immunization work in the second dose, focus on the purpose and significance of strengthening immunization, actively guide the target population to take the initiative to vaccinate, and especially guide and improve the vaccination rate of the elderly population.

On May 16th, the State Council held a press conference on the operation of the national economy in April 2022. Fu Linghui, spokesperson of the National Bureau of Statistics and director of the comprehensive statistics department of the national economy, said that consumption is expected to gradually recover, and online consumption and upgraded consumption will still become an important support for consumption. In April, although the total retail sales of social consumer goods declined, the pace of consumption recovery will accelerate as the impact of the epidemic is gradually controlled. From the experience since the outbreak of the epidemic in the past two years, once the epidemic is effectively controlled and the normal life order is restored, the pent-up consumer demand will be released quickly. In the next stage, the efforts to help enterprises stabilize their posts will be intensified, and the employment base will be generally stable, which is conducive to ensuring residents’ income and consumption power. Benefiting from the development of information technology, some traditional contact consumption has been transferred to online, and the upgrading trend of residents’ consumption will continue, which is conducive to supporting consumption growth.

　　Today (14th), at the press conference held by the State Council Information Office, Sui Jing, director of the Network Security Administration Bureau of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology continued to promote the special rectification of personal information protection of APP. In 2021, 2.08 million apps were technically tested, 1,549 were notified of violations, and 514 were removed from the shelves, which effectively rectified illegal behaviors.

　　Sui Jing introduced that the Ministry of Industry and Information Technology has always attached great importance to the protection of personal information, resolutely implemented the relevant work arrangements of the CPC Central Committee and the State Council, adhered to the people-centered development idea, and based on the main responsibility, accelerated the implementation of the Personal Information Protection Law and the Data Security Law in the industrial and information fields, and achieved positive results in comprehensively promoting data security and personal information protection.

　　The first is to improve the policy standard system. We have formulated the Regulations on the Protection of Personal Information of Telecommunications and Internet Users, studied and drafted a series of documents such as the Measures for the Management of Data Security in the Field of Industry and Informatization, established a standard system for data security in the industry, and guided all units to standardize and strictly promote all work.

　　The second is to organize and promote special governance. Continue to promote the special rectification of APP personal information protection. In 2021, 2.08 million APPs were organized for technical testing, 1,549 were notified of violations, and 514 were removed from the shelves, effectively rectifying violations.

　　The third is to urge the implementation of corporate responsibility. Further promote the improvement of data security protection capability in the field of industrial information, guide and urge more than 500 enterprises to complete self-assessment, and promote the implementation of corporate security responsibilities. Organize telecom enterprises, Internet enterprises and trade associations to carry out personal information protection, and improve employees’ awareness of law-abiding through case interpretation, warning education and industry self-discipline.

　　In 2022, we will also focus on the following aspects:

　　First, continuously improve the management system. We will speed up the promulgation of the Measures for the Management of Data Security in the Field of Industry and Information Technology and the Regulations on the Protection and Management of Personal Information in Mobile Internet Applications, study and formulate data security standards in important areas such as the collection and use of personal information by APP, the Internet of Vehicles and artificial intelligence, and strengthen personal information protection and data security supervision.

　　The second is to continue to carry out special governance. Organize and carry out special management of APP security for bad APPs such as fraud, gambling, network-related black and gray products and suspected malicious programs. Establish the technical ability of bad APP safety monitoring and disposal, and form a closed-loop governance system of the whole process of "active discovery, risk early warning, legal disposal and supervision and accountability".

　　The third is to protect user rights. Focus on the supervision of key responsibility chains, and achieve full supervision coverage for application stores, third-party software development kits, terminal enterprises, and key Internet companies to create a safer information and communication consumption environment.

　　The fourth is to carry out collaborative governance. We will strengthen cooperation with the network information and public security departments, promote the construction of a comprehensive supervision pattern involving government supervision, enterprise self-discipline, media supervision, social organizations and users, and further create a safer, clearer and more reliable personal information protection and data security work situation.

　　How far is it from playing mobile phone every day to illness? Recently, a reporter from qianjiang evening news learned from the hospital that there is a 30-year-old clerk in Hangzhou who deals with computers, keyboards and mice every day, and likes to play with mobile phones during the spare time. As a result, his hands are numb enough to require surgery. Psychologists also warned mobile phone owners that if they keep looking at their mobile phones while shopping, they will spend more money. If you let your mobile phone sleep with you, it will do more harm to your health.

　　Keyboard and mobile phone play too much.

　　In addition to hand numbness, muscle atrophy will occur.

　　Zhou Qi (a pseudonym), 30, keeps her hands on the keyboard at work and keeps brushing her mobile phone at rest. She also has a habit of sleeping on her desk with her hands on her pillow during lunch break. It seems that most people’s living habits have damaged her ulnar nerve. It shows that the right hand is numb and tingling, and it takes a long time to straighten your arm to recover. Even the buttons are awkward, and you can’t even carry chopsticks when eating … … After a series of examinations such as electromyography, Zhou Qi was diagnosed as "cubital tunnel syndrome".

　　The ulnar nerve in medicine is what we usually call "numbness". It is one of the three main meridians on the arm. It starts from the cervical vertebra, passes through the elbow joint, sticks to the inside of the arm and goes down all the way to our ring finger and little finger. It is of great significance to our daily life, and the fine movements of our fingers, such as buttoning, holding chopsticks and holding a pen, can not be achieved without the contribution of ulnar nerve.

　　Frequent elbow flexion and other actions will cause ulnar nerve compression, leading to "cubital tunnel syndrome", which will affect the function of fingers and palms. When the sensory function of ulnar nerve is affected, there will be symptoms of numbness of fingers or palms, and when its motor function is also affected, there will be phenomena such as weakness of fingers or muscles. If it is affected for a long time, it will easily cause muscle atrophy and even cause serious irreversible consequences.

　　Use the keyboard and mouse for a long time, bend your elbows for a long time, or sleep on your desk, etc. Some people have cubital tunnel syndrome due to playing mahjong for several days, and office workers and surgeons are all high-risk groups. In order to completely cure the symptoms, Zhou Qi had to undergo surgery.

　　The doctor reminded that to prevent such diseases, one is: rest.

　　If you repeat an activity, whether it is typing, using the mouse or anything else, it is recommended to take a short break every 10 to 15 minutes to rest your elbow and wrist. During this period, you can stretch and exercise these two parts.

　　Second, keep a good working posture.

　　Adjust the height of the seat to keep the forearm as high as the keyboard. When using the keyboard, there should be no feeling of outward expansion and drooping, so that the elbows and wrists are in a relatively relaxed state.

　　The third is: always be vigilant. Once there is numbness and discomfort in the finger, and it is a constant and persistent feeling, you must not ignore it easily. You should go to the hospital as soon as possible for professional judgment and exclusion.

　　Play mobile phone while walking.

　　Shopping is more expensive.

　　A new study by American scientists shows that if you play with your mobile phone while shopping, it will not only increase the risk of hitting obstacles, but also make people spend a lot of money unconsciously.

　　The research team of Fairfield University asked 231 participants to complete a simulated shopping task. One group of participants restrained themselves from taking out their mobile phones and only paid attention to the goods, while the other group randomly used their mobile phones intermittently for unrelated tasks (such as answering phones, sending and receiving text messages, listening to music, etc.). Both groups of participants used to shop according to a shopping list provided by the researchers, but the results showed that people who used their mobile phones occasionally or constantly in the store made far more unplanned purchases than those who concentrated on shopping.

　　The researchers pointed out that when shopping, people may forget what goods they need most when they are distracted, but they will be attracted by the dazzling array of other goods in the store and take them into their pockets without thinking. Even if you only use your mobile phone occasionally during shopping, it will have this effect, which will lead to additional expenses. Therefore, we should concentrate on saving money when shopping.

　　Wang Yiquan, an expert in early intervention of psychological problems in Hangzhou No.7 Hospital, said: "From the perspective of behavior patterns, those who rely heavily on mobile phones have poor self-control ability, and they are easily influenced by external information such as price reduction and new product listing when shopping, resulting in more impulsive consumption. From the analysis of emotional influence, the information from the mobile phone will affect the mood of shoppers, and these emotions may stimulate impulsive consumption whether positive or negative. Seeing good news, buy something to reward yourself or your family; When you see bad news, you should buy something to comfort yourself and decompress. For example, people often joke that ‘ Bao ’ Treating all diseases is the most vivid explanation of the influence of emotions on shopping. "

　　We have to admit that consumption is indeed a good way to vent and quickly adjust emotions, but only if it is moderate. If it is inappropriate or even unreasonable consumption beyond one’s own ability to pay, one must be alert to whether there are psychological problems.

　　In fact, in life, it is easy to understand the difference between men and women’s shopping habits. For most men, shopping is a kind of "torture". They often think about where to buy something, go straight to the destination and buy it, and then leave. They rarely pay attention to what other stores are selling along the way, and naturally they will not have unplanned consumption. Women tend to take shopping as a kind of "leisure", walk around, shop around, stop and watch more, and the temptation is more likely to lead to many unplanned consumption.

　　Sleeping with your mobile phone is harmful to your eyes.

　　Playing mobile phone for a long time at night often leads to sore eyes, sharp drop in vision, deepening myopia, and even dry eye. Once, because of playing mobile phone games for a long time, the function of meibomian gland was worse than that of the elderly.

　　Everyone’s two eyes have a dominant eye and a non-dominant eye. Under normal circumstances, under the control of the brain, the eyes of both eyes are even, but after lying on the side, one eye has to shoulder a heavier eye task. Over time, if the balance is broken, the vision will be inconsistent between the left and right eyes.

　　Sleeping with mobile phone is harmful to cervical health

　　"Cervical arch inversion" is the most common pathological basis of cervical diseases. High pillow can make the head bend forward and increase the stress of the lower cervical vertebra, which may accelerate the degeneration of cervical vertebra. However, bad living habits such as lying on a high back and watching TV, surfing the Internet for a long time, lying down and playing with a mobile phone, and pulling the cervical vertebra for a long time will also lead to the curve lordosis decreasing, straightening and even bending back.

　　Sleeping with mobile phone affects sleep quality.

　　Adequate sleep is a necessary guarantee for a healthy life. When playing mobile phone, the production of melatonin (secreted by pituitary gland, which directly affects the quality of sleep) will be reduced, which will lead to less sleep and even inability to sleep. I believe those who play mobile phones until midnight or even later have a profound experience — — I’m not sleepy at all. I don’t want to sleep.

　　Sleeping with mobile phones affects family harmony.

　　Young people, once they have cell phone sleepiness, are not in a hurry to find a partner. They think that cell phones are so fun and have everything in them. Why do they need to find a partner? Parents look at the older single children, but they really hate the dead mobile phone. After three days, they cursed, "I know how to play mobile phones every day, and others have grandchildren, so you will give me a mobile phone?"

Recently, a touching love relay was staged on a street in Lishui, Zhejiang. Passers-by stopped one after another, picked up brushes and pigments, and used colors and creativity to revitalize the original monotonous blind road …

The sponsor of the activity is called Fang Cunxin. She is a painting blogger and an optimistic one-armed girl. "When I went out once, I met a blind man who wanted to cross the road. Because the blind road is occupied, I can only accompany the blind man for a while. " Fang Cunxin was deeply surprised by this experience. In the city where she lived for many years, blind people were rarely seen.

This incident prompted her to pay attention to the blind road construction in the city. "Many blind roads are occupied and destroyed by bicycles, and even the colors of many blind roads are dim and almost unnoticed." As a painting lover, Fang Cunxin had an idea, "If passers-by are allowed to leave their own works of art on the blind road, can it arouse everyone’s attention to this’ forgotten corner’?"

After obtaining the approval of the relevant departments, she opened the event with acrylic paint and brushes.

On the first day of painting, Fang Cunxin still needs to shout at the roadside, hoping to attract more passers-by to participate. On the second and third days, hundreds of people have spontaneously joined this street public welfare activity. "At first, I only planned to draw 50 meters, but when I came to my senses, this road has extended far and far." Talking about the scene where everyone actively participated in the activities, Fang Cunxin was very emotional.

"Although they can’t see, we can use this tangible color to pave an invisible road for them. I can keep painting because it is a very meaningful thing. " A girl who participated in painting at the scene squatted at the intersection for several days and created on the ground one by one.

Hundreds of passers-by participated in the painting of "Rainbow Road". Photo courtesy of respondents

Everyone calls this road "Rainbow Road". As Fang Cunxin said, "I hope this rainbow road will be infinitely extended in our hearts, maybe the color will fade, but love will continue!" From one person to a group of people and then to everyone, strangers pick up brushes. In this way, they contribute to the better integration of disabled people into society.

　　Needle puncture, blood drawing, ozone injection, etc., and then the blood is returned to the body … … Recently, a medical beauty project named "Blood Purification" became popular on social media because of many "Amway" in online celebrity. In online celebrity’s sharing posts, it is frequently mentioned that "blood purification" can resist aging, promote metabolism, regulate immunity and help the body to detoxify. Some merchants even claim that it can treat tumors. But is this really the case?

　　A survey by Beijing Youth Daily reporter found that this project, known as "Beauty Black Technology", has been carried out in medical and beauty institutions and private hospitals in Beijing, Guangdong and Nanjing, with a single charge ranging from 3,000 yuan to 50,000 yuan. According to the description of beauty institutions and private hospitals, "blood purification" is simple, safe and reliable. In this regard, medical experts reminded that the "blood purification" project is not suitable for everyone, not a beauty care project, but an operation. Patients in need should follow the doctor’s advice and receive treatment in regular hospitals. "If you operate in an environment that is not up to standard, there will be risks such as blood infection."

　　In addition, the health departments in Beijing, Guangdong and Nanjing all said that they had not approved the relevant qualifications of the beauty institutions and private hospitals involved in this area to carry out such "blood purification" medical beauty projects, and suggested that consumers should report the relevant situation to the health department in time.

　　raise concerns

　　Medical beauty project "blood purification" became popular.

　　Recently, a "blood purification" project has quickly become popular in the medical and beauty circles, and many online celebrity and beauty bloggers have fancy "Amway" on social platforms. Online celebrity mentioned that she experienced the project in Japan by a friend’s recommendation. The steps were simple: pricking a needle, drawing 100 ml of blood, and then injecting ozone. During this time, online celebrity said that he saw his blood "change from dark red to bright red". Finally, the "purified" blood is returned to the body. Online celebrity said that after "blood purification", "I only slept for five hours every day but I was not sleepy at all". The post also showed photos of her "doing projects".

　　The reporter of Beiqing Daily noticed that there are not a few "Amway posts" about "blood purification" on social platforms. A beauty blogger told the reporter of Beiqing Daily that he had done the project in Ginza, Tokyo. "I have done it three times, and it is not easy to get tired after I finish it." In addition to Japan, South Korea and Thailand, many netizens "Amway" medical and beauty institutions in Guangzhou, Nanjing and even Beijing.

　　Despite being sought after by many beauty lovers, netizens have mixed opinions. Some netizens bluntly said that this is paying an "IQ tax"; There are also medical experts who question that once there are irregularities in the operation process, it is very likely to cause injury or even death.

　　Journalist investigation

　　Be touted as an "anti-aging artifact"

　　An unannounced visit by the reporter of Beiqing Daily found that there are not a few beauty and plastic surgery institutions in China that claim to be able to carry out "blood purification" projects. There are two specific forms: one is the direct operation of the plastic surgery hospital; The other is the beauty salon "matchmaking", which leads the passenger flow to private hospitals, which are charged by the beauty salon, but operated by private hospitals.

　　A staff member of a beauty agency named "Qinxin Yimei" located in Fogang County, Qingyuan City, Guangdong Province said that they are doing a "blood purification therapy" introduced from Germany. "Take out your own blood, then mix and purify the high-concentration and high-dose active oxygen with the blood, and then return your own blood to the body." The staff member said, "Many online celebrity and celebrities in China are doing it here, and they can excrete a lot of toxins from the body." Subsequently, the staff sent a number of videos and photos of customers "doing projects".

　　Asked about the charge, the staff sent a leaflet page, which read "1000 ml of net blood is worth 79800 yuan at a time". However, she said that it is more recommended for reporters to "do cards", saying that the more recharge, the lower the single charge price. "After the discount, the single charge ranges from 10,000 yuan to 50,000 yuan."

　　Coincidentally, when the reporter of Beiqing Daily consulted the anti-aging problem as a consumer, the staff of "Nanjing Mijia DR.CICI Plastic Surgery Hospital" recommended a similar "blood purification" project to the reporter of Beiqing Daily. In the video sent by the other party, a woman in a nurse’s uniform kept shaking with a bottle filled with blood, and a patient waiting for "blood transfusion" was lying next to the woman.

　　Seeing the reporter’s interest, the staff further introduced that the agency’s "blood purification" project is divided into two types: large circulation and small circulation. "The price of large circulation is 50,000 yuan, and the price of small circulation is 3,980 yuan. Great circulation is the whole body blood circulation. Blood is drawn from one arm, purified by the machine, and then returned to the body from the other arm. The small circulation is to pump 100ml of blood, then inject ozone into the blood with a machine, and then return the blood to the body. "

　　Beijing luodian

　　Clients are drained to private hospitals.

　　"Great Cycle" and "Small Cycle" have a new expression in a beauty salon named "Kiss of Flowers" in Chaoyang District, Beijing — — "adsorption column" The staff introduced, "‘ Adsorption column ’ Is added in ‘ Blood purification ’ A link in the process will absorb impurities and precipitates in the blood, which will double the efficacy, but the price is relatively high after addition. " Different from the first two cosmetic and plastic surgery hospitals, the staff of "Kiss of Flowers" said that they did not operate the "blood purification" project, and after signing an agreement with customers, they would take customers to a private hospital named "Ciming ‘ao Sub-health Management Hospital" for specific operations.

　　Subsequently, the reporter of Beiqing Daily consulted Ciming ‘ao Sub-health Management Hospital in beiyuan road, Chaoyang District as a citizen. A "health consultant" of the hospital introduced that "blood purification" is a medical beauty project with "anti-aging effect" in the hospital, and admitted that it has "channel cooperation relationship" with many beauty salons.

　　As for the benefits of "blood purification", the above-mentioned staff sent a paragraph saying that the project can "reduce hyperlipidemia and high cholesterol; Eliminate environmental toxins and metals in the body to prevent the occurrence of cancer; Remove endotoxin from the liver and improve the detoxification function of the liver; Treatment and prevention of complications of diabetes; Repair damaged myocardium and blood vessel wall to prevent cardiovascular and cerebrovascular diseases; Improve male impotence symptoms and sexual function, improve immunity; Improve cell activity, rejuvenate the vitality of the body, and effectively prevent premature aging; Improve the symptoms of numbness and fear of cold in hands and feet, make qi and blood smooth, and improve the gloss and whiteness of skin. "

　　No photo receipt, only "medical examination fee"

　　"We are a regular hospital, and physical examination is our main project. If you are not at ease, you can come and have a look in person. " Aware of the reporter’s concerns, the staff of Ciming ‘ao Sub-health Management Hospital took the initiative to make suggestions.

　　Yesterday morning, a reporter from Beiqing Daily and his party came to this hospital in beiyuan road, Chaoyang District. According to the salesperson, "blood purification" is carried out in the "sub-health conditioning center" inside the hospital. "Customers are all members of the hospital, and there are customers brought by the channel, so there is no need to publicize them."

　　Then, two salespeople took the reporter of Beiqing Daily to a consulting room on the second floor of the physical examination center. A "director" wearing a white coat sat down and began to introduce the benefits of "blood purification" in anti-aging to reporters. Subsequently, the salesperson introduced the price of "blood purification". "Yes ‘ Adsorption column ‘ The big cycle is 50 thousand yuan at a time. The small cycle of pumping out a small amount of blood and injecting ozone is not done alone, but combined with the large cycle. The price is 10 times for a course of treatment, totaling 50,000 yuan. " After the reporter of Beiqing Daily asked "whether it is possible to invoice", the salesperson said, "This is our internal price, and we can’t invoice. Even if it is a receipt, we can only write the medical examination fee."

　　During the consultation, in addition to a director, there are two salespeople, a man and a woman, who always follow the reporters of Beiqing Daily, and are not allowed to take photos casually.

　　Subsequently, the reporter of Beiqing Daily asked if it was possible to "look at the departments doing the project", and the staff replied, "It’s a sterile room, and everyone is doing it in it ‘ Blood purification ’ It is not convenient to see. " After repeated requests, two salespeople led the reporter of Beiqing Daily to visit the general ward, and said, "The ward for blood purification is similar to the general ward, but the bed will be better than this." The reporter of Beiqing Daily saw that the bed in the general ward of the hospital is similar to a single or double bed in a hotel. The staff added, "When doing the project, the hospital ward bed is used, and an instrument for blood purification will be placed next to it."

　　Regarding the treatment risk, the sales staff insisted that it was "absolutely safe" and stressed that they had relevant qualifications approved by the health department. A salesperson said, "This is equivalent to the process of blood collection. This arm is drawn out, and after the circulation of the machine, the left arm enters and exits the right arm, and the (filtered) fresh blood is injected back from the other arm. After you finish, you can see a small tube filled with impurities extracted from your blood. "

　　Expert opinion

　　If the environment is not up to standard, there will be the risk of infection.

　　For the "blood purification" medical beauty project launched by beauty institutions and private hospitals, Dr. Wang, an attending doctor in the rehabilitation department of a 3A hospital in Beijing, told the reporter of Beiqing Daily, "What they said ‘ Blood purification ’ The project should be an auxiliary medical project carried out in regular hospitals, which is mainly suitable for the auxiliary treatment of patients with physical pain, herpes zoster, cardiovascular and cerebrovascular diseases, but not for everyone. ‘ Anti-aging ’ The beauty project. Moreover, this is an operation, and even if it is carried out in a sterile operating room of a regular hospital, there will be a certain risk of infection. "

　　Zhu Chenggang, deputy director of the Cardiovascular Department of Fuwai Hospital, said that the blood purification project recommended by some beauty salons and medical institutions costs tens of thousands of dollars, and the curative effect is fantastic, claiming that it can beauty beauty, and even has a miraculous effect on treating tumors, which should be regarded as selling fear and over-publicizing. Zhu Chenggang pointed out that if you want to reduce blood fat and treat cardiovascular diseases, you must go through regular hospitals and use professional machines to achieve blood purification. There is no need for ordinary patients to carry out such treatment. Only patients with a family genetic history or a particularly high blood fat content can apply to such treatment methods.

　　Official response

　　Many health departments said that the project had not been approved.

　　The reporter of Beiqing Daily consulted the health departments in Fogang County of Qingyuan City, jianye district of Nanjing City and Chaoyang District of Beijing where the three medical institutions are located.

　　On February 21st, the staff of the Medical Administration Department of Fogang County Health Bureau in Qingyuan City, Guangdong Province said that the approved practice scope of the beauty hospital involved was cosmetic surgery, cosmetic dermatology and medical laboratory. "It is ok to do it within the skin, which is similar to hemodialysis ‘ Change blood ’ This kind, they don’t have this permission. " The staff said that they do not know the specific situation of this "treatment" in the beauty hospital involved for the time being, and will conduct an investigation according to the complaints of consumers.

　　On February 22nd, the reporter of Beiqing Daily called the Nanjing jianye district Health Bureau, and the staff said that the "blood purification" project described by the plastic surgery hospital involved had not been filed in the unit. "Blood things are no joke, even when many large hospitals are carried out, cases of infection can’t be avoided. We will ask the staff to investigate the specific situation of their project. "

　　On February 22, the reporter of Beiqing Daily called the Medical Administration Department of Chaoyang District Health Bureau as a citizen to ask whether the hospital involved had the relevant qualifications for "blood purification". The staff said that Ciming Aoya Hospital is a private hospital with a medical institution practice license. "If the hospital has a medical beauty department, it can carry out medical beauty services." After listening to the description of the "blood purification" project, the staff clearly stated, "I have never heard of this project you mentioned. You ask him to take out the approval and qualification materials and see what we give him for approval. It’s definitely not this. We have not approved this (blood purification) project here. " The staff suggested that patients who are unwell should go to public hospitals for treatment.

　　The reporter of Beiqing Daily noticed that as early as 2005, the Ministry of Health had issued "Strengthening ‘ Blood therapy ’ Notice of management ". According to the circular, medical institutions in some parts of China carry out so-called "blood therapy" by collecting patients’ blood, carrying out treatments such as magnetic supplement, adsorption, oxygenation, radio frequency, purification and medicine addition, or directly processing blood in patients’ blood vessels by physical methods. The safety and effectiveness of most of these therapies lack scientific research and evidence-based medical evidence, and may cause harm to human body. In this regard, the Ministry of Health proposed that "blood therapy" which has been proved to be safe and effective in clinical application through basic research and clinical research evaluation at home and abroad can be standardized on the premise of clear indications. For example, "ultraviolet irradiation and oxygenation autotransfusion therapy" can be used for clinical treatment of bacterial, fungal and viral infections, low immune function, poisoning and so on. The controversial "blood therapy" should not be provided to patients as a clinical service item. For "blood therapy" which has neither basic research conclusion nor clinical research,All clinical applications will be stopped.

Hu Guohua data map

　Cctv news On March 29, 1984, a young man came to the office of the State Patent Office, which was still painting and laying bricks. He held the card "Patent applicants line up here, the first aerospace institute 207" in his hand, and held it up and hung it on the door frame. When the scattered people around him saw that the young man was the vanguard, they consciously began to line up. This young man is Hu Guohua.

It turned out that in 1984, China’s first patent law was officially promulgated and implemented in April. After learning this news, Hu Guohua, who was working in No.207 Institute of the Second Hospital of the Ministry of Aeronautics and Astronautics at that time, came up with the idea of fighting for the first invention patent and letting the national No.1 patent "blossom" in space. In order to ensure that astronauts can obtain the first patent, Hu Guohua came to the National Patent Office to inquire in advance. He found the office that accepts patent applications. Although he hasn’t officially started to apply, there are already many people around him who are wandering around like him. Hu Guohua had a brainwave and wrote a card "Patent applicants line up here, ranking first in Aerospace Institute 207". People who didn’t know what to do originally were lined up by Hu Guohua.

In the afternoon, Hu Guohua brought bedding and waited outside the office for three days and nights. On April 1, 1984, he was finally the first to submit the patent application. In December 1985, Hu Guohua successfully obtained the certificate with the patent number of "85100001.0" issued by the State Patent Office, and became the "No.1 Patent" inventor of New China. The patent he applied for is called "Variable Optical Filtering Real-time False Color Display Method and Device". Simply put, it is to turn a black-and-white picture of the earth taken from a satellite into a color image according to certain characteristics, so as to see more information.

Do not forget your initiative mind is only because of the space dream.

In 1966, 23-year-old Hu Guohua graduated from the Physics Department of Fudan University and was assigned to work in Beijing Institute of Physics, China Academy of Sciences. In 1970, he took the original research topic and transferred to the 207 Research Institute of the Second Hospital of the Seventh Machinery Department (later the Space Department) to engage in optical research. Since then, the space dream has been deeply rooted in Hu Guohua’s heart and has become the driving force for him to persist in developing products for so many years.

His laser group is the earliest unit to carry out modern physical optics research in China. It started not too late, but because of the new principle, high requirements and low output of scientific research equipment, it needs to spend a lot of foreign exchange to import from abroad. Hu Guohua was very upset when he saw this situation, so he decided to design a set of cheap, universal and systematic modern optical experimental device.

The road to design is full of hardships. The difficulties he encountered were enormous: there was no assistant, no funds, no factory building, and even no laboratory where a newly-developed experimental instrument was placed. Hu Guohua’s difficulties attracted Deng Xiaoping’s attention. With the support of important responsible comrades of the Institute, the Institute, the Ministry and the Central Committee, Hu Guohua’s belief was strengthened, and he worked day and night to develop and tackle key problems.

Once he tried to design a "resettable device" with a reset error of less than one thousandth of a millimeter. He thought about walking and eating, but turned a blind eye to people. One night, he designed another device. Because he used his brain too much, his eyes suddenly turned black and he couldn’t see anything until noon the next day.

In 1980, Hu Guohua also developed the "Holography and Optical Information Processing Experimental System", which consists of 15 sets of more than 60 devices, including lasers, shock-proof platforms, optical and mechanical components. It can do dozens of modern optical experiments, such as holography, laser speckle, image spectrum analysis, spatial filtering and optical information processing, and is widely used. It can make blurred electron microscope images or satellite photos clear, and promote the early realization of optical computers with faster speed and larger capacity than electronic computers. The successful trial production of this experimental system has filled a gap in optical research equipment in China. At that time, only a few countries such as the United States could make and use it.

70-year-old retired to "plant the sun"

As an astronaut, Hu Guohua always has an "aerospace dream" in his heart. He dedicated his best years to the aerospace industry. After retirement, Hu Guohua still insisted on his own aerospace dream and never stopped after his seventies.

In recent years, based on years of research in the field of optics, and considering the future of industrial development, the leaders of 207 research institutes decided to participate in the project competition of developing a large-scale solar simulator in a research institute in Beijing, and formed a research team with optical experts to manufacture a solar simulator with a diameter of two meters. Hu Guohua, who was retired at that time, was one of them.

After studying the information about the manufacture of solar simulators at home and abroad, Hu Guohua began to challenge the research and manufacture of solar simulators according to the requirements of Institute 207. He worked tirelessly. In order to buy the parts for manufacturing the solar simulator, he personally drove around Beijing and found the relevant manufacturers to customize it himself. For a component, he has been to an optical production factory in Tongzhou District, Beijing for many times. Because of the special components he requires, even the technicians who process the components don’t know much about it. Therefore, he became a teacher again, explaining the principles and requirements of manufacturing optical components to technicians.

At that time, Hu Guohua was over seventy years old, and everyone in the team affectionately called him "the elder". Hu Guohua said: "I have never felt that I am a ‘ Elder ’ It’s never too old to learn. " He taught his experience and knowledge to young people without reservation, and at the same time learned from them their enterprising spirit.

Stick to the same as before, the space is boundless

Professional innovation, in life, Hu Guohua is using the knowledge to serve the public.

After retirement, Hu Guohua once created a space haunted house for an old Beijing street in the New Dong ‘an market in Beijing. Through the combination of space sound equipment and sound and photoelectricity, the horrible scene is reproduced. At that time, tourists lined up to experience the sci-fi effect of space sound; Hu Guohua also applied optical knowledge to anti-counterfeiting technology, made anti-counterfeiting trademarks for Xinjiang Tobacco Company, and made contributions to cracking down on counterfeit and shoddy products and raising national tax revenue.

Hu Guohua often uses it to help some poor countries. In April 2016, some scientists and technicians from Malaysia and Indonesia planned to build hydropower stations in some mountainous areas of East Malaysia to solve the lighting and living problems for local people. At this time, they found Hu Guohua, and Hu Guohua immediately planned for them and led them to visit Jinhua, Zhejiang. He brought China’s technology to Southeast Asia, which not only enabled the residents in those areas to use electricity, but also enabled China to transfer technology and gained economic benefits.

But doing all this, Hu Guohua didn’t make a penny. He spends his energy and wisdom to help others, which fully shows the feelings of an astronaut, that is, he is open-minded and generous, and he is willing to do whatever he can, regardless of gains and losses.

For half a century, Hu Guohua’s determination and belief in practicing his space dream need not be repeatedly emphasized. He has been telling people that he is an astronaut and practicing his space dream with practical actions.
