Knight armor catapult giant slingshot goes into battle in Kiev, Ukraine.

The street situation in Kiev, the capital of Ukraine, is getting out of control. Because the contradiction between the opposition and the government is difficult to reconcile, on the evening of January 22, protesters and police clashed bloody in the Independence Square in Kiev, the capital, killing five people and injuring more than 300 people. Witnesses said that four of them were shot and killed by the police, and the fire enveloped the whole city center. The scene was described as a "war blockbuster".

Ukraine has always been very strict in gun management. Proceeding from the principle of legal possession of guns and self-defense, the Ukrainian Ministry of Internal Affairs has determined the principle that guns must be registered by the state, the principle of production license and the principle of bringing them into the country. It is forbidden to use silencers and accessories with night vision sights for official and civilian guns in Uzbekistan. The purchase of guns must hold a special license from the Ministry of Internal Affairs of Ukraine, valid for 3 years. Therefore, although both the demonstrators and the police used guns in the conflict, the police mainly used them to fire tear gas and rubber bullets to disperse the demonstrators, and the number of guns of the demonstrators was also very small. Most conflicts are caused by the use of sticks, shields and other weapons by both sides.

Street demonstrations in Ukraine have evolved into serious violent confrontations.

Street demonstrations in Ukraine have evolved into serious violent confrontations.

During the conflict, the Ukrainian police took strict organization, and a large number of policemen wearing full-body protective gear, helmets, shields and batons formed a "human wall" at the scene of the conflict to stop the violent actions of demonstrators. Not to be outdone, the opposition not only robbed many police weapons and equipment, but also "self-developed" many weapons similar to those of the ancient war against the police, which made this conflict take on many "medieval" colors.

shield

In the conflict, both sides used a large number of shields as formations to defend against all kinds of tear gas and fireworks thrown by opponents. Most of the demonstrators’ shields were seized from the Ukrainian police, and these shields were simply decorated and distinguished with paint. Of course, more so-called shields are mainly a board. At other times, however, a few carefully decorated shields also appeared at the demonstration site. These shields are larger in size, better in material and stronger.

A set of shields used by demonstrators in Kiev. They should be made of plexiglass and can be easily carried by demonstrators. The red cross and green background on the shield give people a sense of medieval war.

When the police fired tear gas, this group of demonstrators formed a tortoise shell array with great literacy to prevent the crowd from being dispersed by tear gas.

Another shield painted with the Red Cross looks like a crusader. A demonstrator is hiding behind a shield and firing a rocket at the police.

rocket

In response to the police’s use of tear gas, many demonstrators also fired a large number of fireworks for festivals. Many people lit fireworks from water pipes and fired them at the police, and combined with throwing stones and burning bottles, they tried to stop the police from expelling.

The rocket flying out of the steel pipe shows that the demonstrators with shields in front are facing the police against the barricade.

A demonstrator who is launching a rocket has a handful of "ammunition" waiting to be launched.

However, it would be a big mistake to think that rockets are the most advanced weapons of the opposition. In order to completely overwhelm the police, the opposition demonstrators also created several real "big guys".

　

　

Siege machine

At least one wooden trebuchet and a giant slingshot were assembled and used in demonstrations in Kiev, the capital of Ukraine, to shoot stones and other sundries at the police.

There are many curious demonstrators watching the trebuchet being assembled.

The trebuchet, which was completed at night, was planned by the demonstrators to throw all kinds of sundries at the police.

This is not a real-life version of "Angry Birds", but a demonstrator using a homemade giant slingshot to shoot stones at the police. Being hit by something like this is not fun at all.

Another huge slingshot, the demonstrators in front are trying to stabilize the support, while the people behind are shooting stones.

Demonstrators and bystanders

In addition to the large weapons on the scene, demonstrators also used various means to protect themselves. Helmets, goggles and thick coats are common equipment. What’s more, it also moved out the knight armor that may have been handed down from family.

Demonstrators armed with sticks and ready for battle can see that helmets, goggles and masks from all sources are standard.

The demonstrator even put on a knight’s armor from nowhere. Although it is not a complete set, it is definitely cool.

It is necessary for journalists who walk through the crowd on both sides to hold a bowl in order to prevent "accidental injury"

Lulang town, Linzhi city： an ecological town has set up a golden rice bowl for tourism

　　Editor’s note: 70 years of thorns and thorns, 70 years of hardships. This year, People’s Republic of China (PRC) will celebrate its 70th birthday. Under the leadership of the Communist Party of China (CPC), the people of the whole country are determined to forge ahead and strive for self-improvement, and have made remarkable achievements in construction, and earth-shaking changes have taken place in China society.

　　In every inch of China, 70 years have left a touching historical mark, and each city has its own story. On the occasion of the 70th anniversary of the founding of New China, People’s Daily planned to launch a series of reports on "The Story of the Country Spanning 70 Years". The reporter recorded the development and changes of various places in the past 70 years through videos, pictures and words, and showed the prosperous happy life picture of the country from small to large, and felt the majestic power of the new China in the vivid historical changes.

　　Doing tourism means doing ecological economy.

　　Blue sky, clear water, green hills and green spaces are the capital and family property of tourism development.

　　Crossing the Sejila Mountain from the 318 National Road, in front of us, Lulang Town in midsummer is wrapped in a vast forest, full of lush, blue sky. In 1911, Chen Quzhen, an officer of the Qing army, wrote in "A Dream of Wild Dust" that the area around Lulang was "all ancient trees in the mountains, surrounded by ten big trees, with a height of several tens of feet, standing upright in the sky and hiding in the shadows". Nowadays, this land moving with "green" is gaining momentum and banners are flourishing.

　　Lulang Town, located in Bayi District, Linzhi City, Xizang Autonomous Region, is famous for its "snow-capped mountains and beautiful forests, clouds and rosy clouds, one ridge with four seasons and nine scenic spots in ten miles". Under the nourishment of green mountains and green waters, the people in Lulang Town have won the "golden rice bowl" by relying on eco-tourism. Through the continuous development of "ecological+"tourism, they have embarked on the road of eco-tourism economy, and painted a picture of Lulang’s happiness of "ecological beauty and rich people".

　　Play the ecological card skillfully, and Qingshan will become a "golden mountain"

　　"More than 40 years ago, the income of ordinary people here mainly depended on cutting trees and hunting. As long as there were difficulties, they went to the wood to make ideas, and only earned more than 2,000 yuan all year round." Zhaxi Tsering, secretary of the League branch of Zhaxigang Village in Lulang Town, said that at that time, some originally dense virgin forests disappeared in a few years.

　　The result of pursuing temporary economic growth at the expense of ecological environment is the sharp decline of forest area and the decline of ecological quality. With the decrease of trees, Lulang’s economy is gradually in trouble.

　　Learn from a painful experience. The local authorities re-examine the resources, optimize the ecological environment, and change the green hills into "golden mountains". In 1998, Xizang Autonomous Region implemented a comprehensive ban on logging in forest areas, and the central and autonomous regions continued to increase the protection and construction of forests in eastern Tibet; The "wood finance" that used to make a living by selling wood began to fade out of this small town in southeastern Tibet.

　　Since the logging ban, Lulang Town has actively changed the economic development mode of forest areas and vigorously advocated ecological economy. Over the past 20 years, local farmers and herdsmen who rely on forests to eat forests have embarked on the road of eco-tourism to develop the economy.

　　In the midsummer, walking into Zhaxigang Village, Lulang Town, located on National Highway 318, rows of two-story Tibetan courtyards are particularly beautiful under the flying national flag. The front and back of every house are full of flowers and trees, dotted with beautiful homes.

　　Pingcuo Family Inn. Chai Jidong

　　Stepping into the family hotel in Pingcuo, the walls and furniture painted with Tibetan patterns, the big stone pot for making stone pot chicken, the Tibetan-flavored pork hanging from the beams, and the small bags of highland barley all reveal a strong collector atmosphere.

　　"In 1998, an accidental opportunity gave me the idea of opening a family hotel when I was a guide for tourists." Pingcuo, a villager in Zhaxigang Village, Lulang Town, who was born before the peaceful liberation of Tibet and worked as a slave, told reporters. In 1998, Pingcuo earned more than 20,000 yuan from family hotels, becoming the "first person to eat crabs" in the village.

　　Pingcuo introduced that at the beginning, the county gave the village a discount loan of 800,000 yuan, 40,000 yuan for one household, and the first batch of 20 households were supported to develop family tourism and repaid within three years. "My family hotel is relying on the policies of the party and the state to continuously expand its scale, and the number of beds has increased from the initial 8 to 53; From the annual income of 20,000 yuan to 30,000 yuan to the current 400,000 yuan. "

　　Seeing the real changes in Pingcuo’s family, villagers around Lulang Town have also started family hotels, with an average household income of more than 100,000 yuan per year. Compared with thousands of dollars earned by farming and herding cattle a year, it is almost unimaginable. According to the data, 272 farmers and herdsmen in 8 administrative villages in Lulang Town have opened 116 family hotels. Last year, they received 70,800 tourists and earned 8,037,200 yuan.

　　"As the saying goes, people in the village used to go up the mountain to cut trees to support their families. Now we are protecting the ecology. As long as we protect the sky here, we will have food." Pingcuo said confidently.

　　In Lulang, the concept of ecological protection has penetrated into the hearts of farmers and herdsmen.

　　The former "loggers" have also become today’s rangers. "By doing a good job as an ecological ranger, we not only solved the employment, but also protected the environment." Nima Tsering, deputy director of Zhaxigang Village Committee, said, "Now our country subsidizes one mu of public welfare forest in 5 yuan, and the management area of public welfare forest in Lulang Town is more than 1.8 million mu, which has benefited a lot."

　　At present, Xizang Autonomous Region has established perfect ecological compensation mechanisms such as transfer payment for key ecological functional areas, compensation for forest ecological benefits, subsidies and awards for grassland ecological protection, and compensation for wetland ecological benefits. Up to now, 31.6 billion yuan of various ecological compensation funds have been implemented, which has enabled nearly 700,000 farmers and herdsmen in the whole region to eat "ecological rice" steadily.

　　Facts have proved that relying on ecological environmental protection to bring about vigorous economic development and let the green mountains and green waters release dividends is the broad road for the people to be rich.

　　Read the "travel classics" well and drum up the "money bag"

　　In the Caiwang Dunzhu Family Hotel in Luobu Village, Lulang Town, the family is busy entertaining tourists who come to their home. Cai Wangdunzhu happily introduced his modern family hotel. The reporter saw that the family hotel in Caiwang Dunzhu was very clean and tidy. In addition to the corresponding supporting facilities, it also achieved full coverage of Wi-Fi.

　　"When tourists saw that our facilities were poor and the sanitary conditions were not good, they turned their heads and left." Cai Wangdunzhu recalled. In the initial stage of operation, problems such as malicious competition and tourists’ complaints often occur in Lulang Town. The original buildings in the town have no planning, no style and the phenomenon of private construction is also prominent.

　　"At that time, we have been pursuing quantitative growth and neglected the experience comfort of tourists." Bianba, secretary of the Party Committee of Lulang Town, said that although the vigorous development of family hotels has made the people taste the sweetness, the extensive management and loose management have made tourists feel dissatisfied.

　　How to realize the sustainable development of characteristic tourism has become a difficult problem in front of the development of Lulang Town.

　　According to Bianba, in order to further improve the service quality, the government gave financial subsidies to upgrade the hotel hardware. "With clean toilets and comfortable beds, tourists have a good place to experience traditional Tibetan dwellings. The improvement of quality has led to an increase in quantity. "

　　Looking from the window on the second floor of Caiwangdunzhu Family Hotel, some tourists are experiencing folk activities such as horseback riding and archery on the grassy pasture. "After entering May, I was full almost every day, and the room had to be booked two days in advance, and there were many repeat customers." Cai Wangdunzhu said with a smile.

　　In 2017, with the counterpart support of Guangdong Province, Lulang International Tourism Town (hereinafter referred to as "Lulang Town") with a total investment of 3.8 billion yuan opened its doors.

　　Tsering Robb, a villager in Zhaxigang Village, Lulang Town, who has been engaged in catering and accommodation business, said: "After the completion of Lulang Town, there are many more tourists than in previous years, especially the cultural tourism festival and stone pot banquet for thousands of people in Lulang Town. It has gathered more popularity for the town." Tsering Rob, who is quite business-minded, opened a stone pot chicken restaurant in the commercial street of the newly-built town of Lulang, which gave him another income. There are not a few local people like Tsering Rob who have benefited from the project in Lulang Town. Due to the increase of tourists, the demand and price of various under-forest products have increased, and the income of farmers and herdsmen has also increased accordingly.

　　Stone pot banquet for thousands of people. Chai Jidong

　　Walking on the streets of the town of Lulang, there are pictures of vendors wearing work clothes and Tibetan clothes waving to tourists to promote their local products. Matsutake, Tricholoma matsutake, Ganoderma lucidum, and Panax palmatum … … It is the capital of Lulang people to run a well-off life.

　　"Now in Lulang Town, the environment is cleaner and more orderly, the supporting facilities are more perfect, the regional formats are increasingly rich, and the people are more market-conscious." Talking about the changes that Lulang Town has brought to the local area, Wu Xin, the captain of the village team in Lulang District, has many feelings: Lulang Town has provided thousands of jobs for local farmers and herdsmen from construction to operation, and employment at home is becoming a new landscape for Lulang people to increase their income.

　　"Now, farmers and herdsmen in Lulang Town have tasted the sweetness of eco-economy through green industry, and every household has remembered ‘ Tourism classics ’ 。” Hu Xiongying, a member of the Party Group of the Management Committee of Lulang Town and the head of the Industrial Planning Section, was very emotional. In 2018, the number of receptions in Lulang Town exceeded 1.11 million, and the total tourism revenue was nearly 70 million yuan. "This is the charm of eco-tourism driving people to increase their income and get rich."

　　Promote smart travel and create new formats.

　　Pingcuo, a villager in Zhaxigang Village, Lulang Town, is a "WeChat control". "As long as the guests are willing, we have all added, and the circle of friends has been expanding. Now it has exceeded 1,000 people." In recent years, even tourists from France, the United States, Malaysia and Japan will come here.

　　Tourists visit Lulang. Provided by Lulang Scenic Area Management Committee

　　The business card of Pingcuo’s family hotel is printed with a QR code. When the mobile phone is swept away, it is a big surprise: this QR code is not a QR code of a WeChat friend, but a panoramic VR display of his home.

　　"Many tourists saw the conditions of the family hotel through the panoramic VR display and immediately decided to stay." As Pingcuo was saying, a tourist sent a WeChat voice asking about the specific location of Uncle’s home. I saw that at the age of 71, he skillfully opened WeChat location sharing and told tourists to navigate over.

　　"I used to pick up all the guests. Now that the network is developed, tourists all make reservations online and use mobile phone map navigation to come directly to my home. " Pingcuo told reporters that these all benefited from the informatization construction of rural tourism — — With the guidance and help of the local government, villagers who run family hotels and develop rural tourism in the village have learned micro-marketing.

　　In order to improve the quality of rural tourism development and increase tourism income, Linzhi City has integrated more than 10 million yuan of funds from all parties, adopted the model of "tourism+network+farmers", and selected 149 family hotels in 8 villages including Zhaxigang as pilots, taking the lead in launching the rural tourism informatization construction in Tibet.

　　"Linzhi Smart Rural Tourism Informatization Database organically integrates scenic spots, family hotels, traffic information and special products vertically, and effectively connects information such as source market, product supply and sales channels horizontally, realizing online and offline integrated marketing of rural tourism, which has effectively promoted rural tourism to improve quality and efficiency." According to Wu Xin, the captain of the village team in Lulang District, the number of tourists received by family hotels included in the pilot project of rural tourism informatization construction has doubled compared with that before the pilot project.

　　Today, Zhaxigang village in Lulang town has been included in the rural tourism information construction project in Linzhi city, and has entered the era of smart tourism.

　　In the era of mobile Internet, Lulang’s tourism has become three-dimensional, rich and "intelligent".

　　In 2016, Lulang Chuangke Shuangchuang Industrial Park (hereinafter referred to as "Lulang Chuangke Center") came into being. With the theme of "scientific and technological innovation", "cultural innovation" and "double innovation+tourism", the park improved the format of Lulang Town, promoted the coordinated development of various industries, and added new impetus to the development of Lulang smart tourism.

　　Walking into the tourist experience center of the park, there is a big screen on which the four seasons scenery of Lulang Scenic Area changes. Visitors can change the scenery with just a wave of their hands. "Wearing VR glasses, you can experience the high-altitude perception overlooking Lulang Scenic Area, which is really a different experience." Tourist Ms. Zhang said. In addition, through video pictures, visitors can also see information such as "eat, live, travel and buy entertainment" of Lulang, and enjoy more comfortable and convenient interactive experience services.

　　"We must rely on the smart tourism platform to accelerate the construction of smart tourism supported by big data applications, achieve deep integration with the Internet in many fields such as new tourism services, new formats and new models, and realize innovative development to create new product forms and new industrial formats for Lulang’s global tourism, making Lulang’s global tourism more dynamic due to the Internet." Hu Xiongying, a member of the party group of Lulang Town Management Committee and head of the Industrial Planning Section, concluded.

　　If the ecological environment is the "life" of Lulang, then the tourism industry is the "blood" of the people’s livelihood economy, and smart tourism is the "future" of Lulang’s internationalization process. Nowadays, rural tourism in Lulang is changing from simply looking at scenery to experiencing tourism and intelligent tourism. "It is precisely because of the prospect of rural tourism development that Lulang is actively promoting the transformation of smart tourism to the whole town, the whole industry and the whole people. Lulang people are also developing more projects to retain tourists." Hu Xiongying said.

　　Ecological green, prosperous industry and affluent life, the road of "green development" in Lulang Town is a microcosm of Tibet’s regard of tourism as the best combination of "green mountains and green hills" and "golden mountains and silver mountains". Nowadays, the green development concept of "green water and green mountains can get rich" has penetrated into the hearts of people of all ethnic groups in Tibet, and the infinite charm of "revitalizing the beautiful economy by relying on ecological industries" is blooming on the snowy plateau.

Shanghai community has come up with new measures to solve the ＂slot point＂ of garbage classification

　　On July 1st, the Regulations of Shanghai Municipality on Domestic Waste Management was officially implemented. In Baoshan, Shanghai, citizens are using the "Love Recycling" intelligent sorting and recycling machine. Wang Chushe (People’s Vision)

　　Shanghai has implemented mandatory classification of domestic waste for half a month. Shanghai residents carefully study the knowledge of classification, while the managers of grass-roots community organizations try their best to find new ways to solve their problems and do a good job in garbage classification.

　　The reporter recently visited several communities in Xuhui District, the central city of Shanghai, to see what tricks are available for promotion.

　　Access cards act as supervisors.

　　Twelve villages in Tianlin are typical old-age housing communities in Shanghai, with more than 6,000 residents, nearly 1,400 over 60 years old, and the housing rental rate is close to 30%.

　　In the comprehensive management of the community in 2016, Twelve Villages in Tianlin realized the real-name registration of access cards for residential buildings, and became the first smart community platform in Tianlin Street in May 2018.

　　How to make the smart community platform a helper for household waste sorting? Neighborhood Committee cadres came up with a coup to "bind" the access card with the garbage room. Residents swiped their cards to throw garbage, and the management platform automatically registered the card swipers, opening time, card swiping times and green account points of the garbage room.

　　In view of the fear of throwing different garbage at several doors in rainy days and soiling hands with wet garbage, the community has carried out "six-in-one" hardware transformation for all garbage bins: configuring an access control system, installing an awning, installing an inductive sink, adding a set of cameras, a driving mirror and an electronic display screen.

　　A small camera is installed on the gate of the wet trash can with high garbage purity in the community, which is networked with the community management platform. At the same time, the wet garbage pickup truck of the sanitation department is also equipped with an induction probe. Once the wrong garbage is put in, the pickup personnel will find and inform the neighborhood Committee, retrieve the video data of the corresponding numbered trash can, and lock the residents who are not put in place. "No one comes to find the right one, and the wrong one can be traced back at any time", which greatly reduces the supervision cost.

　　The electronic screen on the garbage bin room instantly displays the data such as the total amount of garbage collected on that day and the separation rate of dry and wet garbage, so that residents can intuitively feel the effectiveness of garbage sorting.

　　After more than a year’s efforts, the "fixed-point" delivery rate of residents in Tianlin Twelve Villages reached 90%. On the basis of basic habits, from June this year, the street set a wrong time drop-off point in the southeast corner of the community to open access control "sub-cards" for some residents’ hourly workers and night shift workers to facilitate different people to drop garbage.

　　"We must strictly enforce hard constraints, but also fully consider the needs of residents and provide humanized services." Zhao Guoqing, secretary of the General Party Branch of Tianlin Twelve Villages Residential Area, said.

　　Alipay makes an appointment to recycle large pieces of garbage.

　　Open Alipay, enter the page of garbage sorting and recycling, click on "Booking for recycling of large pieces", select specific categories such as coffee tables and sofas, complete the payment price estimation according to the standards such as materials, disassembly, volume, service life, damage degree and floor condition, and then upload photos of large pieces to be recycled and specify the door-to-door time, and the order will be placed. This is the operation flow of the door-to-door recycling business platform for large-scale garbage in Hunan Road Street, Xuhui District, Shanghai.

　　Aunt Chen, who lives in Lane 55 of Wuyuan Road, has two pieces of furniture that have been idle for a long time. She has been unable to find a suitable way to deal with it. On WeChat group, she saw the notice about home recycling sent by the neighborhood Committee and tried it quickly. I didn’t expect the recycling master to come the next morning.

　　There are five members of the recycling and removal team, all of whom are "professionals" with many years of experience in garbage removal. They wear uniform blue overalls and drive vans. What is to be recycled is a wooden folding bed and a low table. As soon as he entered the door, the recycling team quickly took a photo of the bed and the table respectively. "You have to compare the photos first and take photos to leave a certificate." After the confirmation is completed, the recycling team starts the handling — — Two people are responsible for the folding bed, half open and walking sideways; The low table is carried by one person, and the long side stands up. The corridor in the old residential area is narrow and there is no elevator. Only by using the thinnest handling method can the furniture go downstairs smoothly. It takes less than five minutes to send the doorway from the fifth floor to load it into the truck. Master Sa, who led the team, said that the recycled large pieces of furniture will be sent to the designated recycling point for classification, and the good quality will enter the recycling link, and the poor quality will be treated in a centralized and standardized manner according to the construction waste standards.

　　Aunt Chen paid less than 50 yuan’s freight for these two pieces of old furniture, which she thought was reasonable. "A few years ago, I handled an old sofa myself, and it took more than half an hour to move the sofa down from the fifth floor."

　　Dong Wei, secretary of the Party Working Committee of Hunan Road Sub-district Office, said that there are many traditional lanes in Shanghai, and the living area is small, and the waste furniture still occupies the place. Residents have a great demand for recycling large pieces of garbage. "From the perspective of urban management, the recycling of large-scale garbage cannot rely on ‘ Guerrilla ’ 。” The street is connected with Alipay platform and recycling and clearing team, the price standard is set with reference to the market level, and the operation page is optimized to facilitate residents to place orders quickly, which not only solves the needs of residents, but also reduces the phenomenon of littering.

　　The recycling bin returns to the city center.

　　Recently, a green hut appeared at No.37, Donghu Road, Hengfu Scenic Area, one of the "noble lots" in Shanghai — — "Indus resource space". This is another innovation in garbage sorting in Hunan streets: a resource recycling station combining intelligent trading with manual trading.

　　"Collect scrap metal, waste plastics and waste newspapers … …” Whenever the bell rings in the alley, the residents of the community come out to sell waste products. This is a scene that many Shanghai residents remember. Nowadays, there are fewer and fewer people selling waste products in the streets, and there is no place for daily waste products to be left at home.

　　Hunan street came up with the idea of returning the "upgraded" waste recycling station to residential areas. The "Indus Resource Space" covers an area of nearly 20 square meters and is located at the intersection of five roads, namely Donghu Road, Xinle Road, Changle Road, Fumin Road and Yanqing Road, which can radiate many surrounding communities.

　　The LCD screen at the entrance of the recycling hut shows the prices of various recycled items such as glass, metal, plastic, paper and fabric. Recyclable items sent by residents and enterprises will automatically print out information such as weight and amount after being weighed by staff. The concentrated waste products are collected by professional resource recycling enterprises on a regular basis.

　　On the way to the stadium for exercise, Aunt Wang conveniently carried several cartons that had been flattened and packed. "The recycling price of cartons here is 4 cents more than that sold to scavengers per kilogram of 1.2 yuan. I have been here twice. "

　　"Indus Resource Space" is open regularly every Monday to Saturday. What should office workers do if they miss the opening hours? "Wutong Resource Space" has set up a 24-hour intelligent self-help exchange speculation at the gate. Residents use the mobile APP to scan the code to open the door of the corresponding category. After completing the transaction, they will automatically return the account to the mobile phone.

　　Kitchen garbage does not leave the community.

　　Wet garbage accounts for 60% of the total domestic garbage in Shanghai, and the transfer process is easy to cause secondary pollution to the environment, which is the difficulty of garbage disposal. On June 25th, the Citizen Environmental Protection Experience Center of Hongmei Street in Xuhui District was opened to explore a new mode of wet waste treatment, which is "kitchen waste does not leave the community". Hongmei Street has jurisdiction over 22 residential quarters with about 30,000 community residents. There are 3,000 enterprises and about 280,000 white-collar workers in caohejing Development Zone. Streets began to promote garbage sorting in 2016. By improving the hardware transformation of garbage bins, putting wet garbage in fixed time, "broken bags", on-site demonstration and supervision by volunteers, redemption of points and other supporting measures, residents gradually developed the habit of garbage source sorting and became one of the 18 demonstration streets of domestic garbage sorting in Shanghai.

　　Hongmei Street and Eco-tech Enterprises within its jurisdiction — — Tianwei Environmental Protection cooperated hand in hand to transport the wet garbage from residents’ living quarters and the kitchen garbage from enterprises in the development zone to the nearest citizen environmental protection experience center and three other centralized disposal points, and then put it into special equipment for about 15 minutes, so as to separate out reclaimed water, oil that can be used for biodiesel processing, and compost raw materials rich in biological strains.

　　The key to realize effective biological treatment of wet garbage is that the purity of wet garbage must reach more than 90%, that is, the doping degree of other garbage in a bucket of wet garbage should not be higher than 10%. Hongmei Street specializes in the whole process of wet garbage from delivery, removal to final disposal. At present, the street handles nearly 25 tons of kitchen waste every day, which improves the garbage infiltration pollution caused by long-distance transportation and transit, reduces the removal cost and improves the efficiency of resource localization.

　　Hongmei Street Citizen’s Environmental Experience Center covers an area of 350 square meters. The architectural design is characterized by the unique brick and wood structure with overhangs, the cloister of pond water and the cultivation of various plants, which embodies the concept of symbiosis between man and nature. Here, citizens can visit the whole process of kitchen waste from classification, centralized treatment to resource utilization.

　　Pu Yapeng, secretary of the Party Working Committee of Hongmei Street, said that "kitchen waste does not leave the community" not only requires effective management methods, but also innovates the removal process. "Data can best reflect the results of garbage classification". Every day, the street counts the removal amount of dry and wet garbage, detects the purity of wet garbage, and promotes management efficiency through quantitative management. "

CCTV exclusively disclosed the inside story of 69 hemodialysis patients infected with hepatitis C in Dongtai, Jiangsu.

CCTV News:Recently, some media reported that hepatitis C infection broke out in hemodialysis patients in Dongtai People’s Hospital of Yancheng City, Jiangsu Province. Today (27th), Dongtai Municipal People’s Government responded to this matter.

According to the report of Dongtai Municipal People’s Government, on May 13th, Dongtai Municipal Health and Health Commission received a report from the Municipal People’s Hospital that hepatitis C antibody was newly positive among hemodialysis patients in the blood purification center of the hospital, and it was suspected that nosocomial infection occurred.

On the 19th, the National Health Construction Committee sent an expert group to Dongtai.

After consultation with the members of the expert group, on May 17th, the treatment plan for 69 infected people was determined. Specific measures were taken to treat 69 infected people with antiviral drugs. Among them, 11 patients with transaminase higher than 200 were admitted to hospital. Another 58 people received outpatient treatment. The expenses incurred during this period shall be borne by the hospital. According to Chu Xudong, director of the Infectious Diseases Department of Dongtai People’s Hospital, the 69 infected people are in stable condition and have no adverse reactions during taking the medicine.

According to Cao Guoping, chief of the medical and political department of Dongtai Health Construction Committee, it was confirmed by the expert group that the main reasons for the incident were the disinfection of the hands of medical staff, the disinfection of related equipment used during dialysis, and the irregular implementation of disinfection measures in dialysis areas.

The second reason is that the human resource allocation in the hemodialysis room is insufficient. According to industry regulations, each nursing staff is generally responsible for the operation of six dialysis machines, but in actual work, each nursing staff in this hospital is responsible for the operation of at least nine machines.

The third reason is that the hemodialysis isolation zone of hepatitis C patients in the hemodialysis room of this hospital has the problem of sharing channels with the normal dialysis zone.

In the end, the expert group composed of the state, province and city found that this incident was an nosocomial infection incident caused by the inadequate implementation of the hospital nosocomial infection management system.

According to the requirements of the national, provincial and Yancheng Health and Health Commission, Dongtai City is organizing a special inspection of nosocomial risk in the whole city to further standardize the diagnosis and treatment behavior, and ordered Dongtai People’s Hospital to quickly implement the rectification plan according to the opinions of the expert group, aiming at the existing problems, and rectify it within a time limit.

Sixteen responsible persons were held accountable.

At the same time, 16 responsible persons were seriously held accountable.

Give Zhu Fabing, director of the Medical Affairs Department of Yancheng Health and Health Commission, an admonishing conversation;

Ma Fan, deputy director of the Medical Affairs Department of Yancheng Health and Health Commission, was given an administrative warning;

Sun Yanchun, deputy mayor of Dongtai Municipal People’s Government, reminded the conversation to be handled;

Cui haijie, director of Dongtai health and health commission, talked with him;

Chen Zhang, deputy director of Dongtai Health and Health Commission, was given an administrative warning;

Cao Guoping, chief of the medical and political department of Dongtai Health Construction Committee, was given an administrative warning;

Yin Weiguo, secretary of the Party Committee and president of Dongtai People’s Hospital, and Song Xiaoping, vice president in charge, were dismissed and given different degrees of punishment to other responsible persons.

360 Zhou Hongyi fired again： GPT 6-8 will have a sense of autonomy. Let’s measure right and wrong.

Recently, Zhou Hongyi of 360 said."GPT6 to GPT8 artificial intelligence will generate consciousness and become a new species.In the future, the artificial intelligence big language model may realize self-evolution, automatic system updating and self-upgrading, or exponential evolution ability, and human beings will face unpredictable security challenges. "

Zhou Hongyi, as a "master of tuyeres", has to get involved in almost every tuyere. What he said is somewhat credible, and it is necessary to make a big question mark.

Moreover, Zhou Hongyi only gave a prediction, but did not give his own reasons and reasoning logic.

As a media that focuses on the depth of the industry, we should not stay on the slogan of the headline party, but analyze the problem from a deeper level.

Will GPT grow into a general artificial intelligence model? If so, how long will this process take? Next, we try to discuss this disturbing problem together.

To answer this question, we need to "tear down" a big model like GPT and see what is inside it and how it works.

"Unpack" the black box of the big model

Large model refers to a neural network model with a very large number of parameters, which is usually used to deal with complex natural language processing, image recognition, speech recognition and other tasks. The core elements of the large model are mainly neural network, layer, neuron and parameters.

Data ape mapping

neural network

Neural network is a machine learning algorithm, which is inspired by the nervous system of human brain. It consists of multiple layers, each layer contains multiple neurons, and the connections between layers form a neural network. Each neuron receives the input from the neuron in the upper layer, calculates the output according to its input, and then passes it on to the next layer.

floor

Layer is a part of neural network, which is composed of multiple neurons. Each layer can be configured with different parameters such as activation function and optimizer. Usually, each layer will transform the input and then pass the output to the next layer. Common layers include fully connected layer, convolution layer, pooling layer, etc. The basis for dividing different types of layers is mainly the type of data processed, the internal structure of layers, the functions of layers, etc. For example, the fully connected layer is the simplest and most commonly used layer in neural networks. Its core function is to connect all neurons in the upper layer with all neurons in this layer. This connection allows the neural network to learn the complex nonlinear relationship of input data. Fully connected layer is usually used for image classification, speech recognition, natural language processing and other tasks; Convolution layer is the core layer of Convolution Neural Network (CNN), which is used to process data with spatial structure, such as images. Its core function is to perform convolution operation on the input data through a set of learnable convolution kernels to extract the features of the input data. The internal structure of convolution layer includes several convolution kernels and a bias term, and the output of convolution layer is usually input into pooling layer.

neuron

Neurons are the basic units in neural networks,Its main function is to receive signals from neurons in the input layer or the previous layer and generate output signals. The inputs of neurons are transmitted through a set of weighted connections and are weighted and summed in neurons. Then, this sum is input into the activation function for nonlinear transformation to produce the output of neurons.

The core of neuron is activation function, which is the core component of neuron processing input signal. Neurons receive input signals, sum them with weights, and then input them into the activation function for nonlinear transformation.The function of activation function is to introduce nonlinear factors into neurons, so that neurons can learn nonlinear models, thus improving the expression ability of models.

parameter

Parameters refer to variables in the neural network, which will be updated with the training of the neural network.Each neuron has a weight vector and an offset term, which are usually called parameters.The values of these parameters will be updated by the optimizer during training to make the output of the neural network as close as possible to the expected output.

To sum up, neurons are components of layers, and layers are components of neural networks. Parameters are stored in neurons, and each neuron has a set of parameters (weights and offsets). During the training process, the optimizer will update these parameters to make the output of the neural network as close as possible to the expected output.

So, how do neural networks, layers, neurons and parameters work systematically?

Next, we take the training process of GPT-4 as an example to illustrate the cooperation process of different elements in the training process of large model, specifically:

1) Firstly, all parameters of GPT-4 model are randomly initialized, including the weight and deviation of each neuron in the neural network.

2) Prepare data sets, which can be marked texts, such as articles, novels, papers, social media posts, etc. Before training, data must be preprocessed and cleaned up, such as deleting special characters, stop words and other irrelevant information.

3) Training data will be divided into several small batches, usually each batch contains hundreds to thousands of text samples. Input each batch into GPT-4 model, and the model will calculate the output according to the current parameters, that is, predict the probability distribution of the next word.

4) Calculate the loss function of the model, which can reflect the performance of the model on the training set. In the case of language model, cross entropy is usually used as the loss function.

5) Calculate the gradient of parameters according to the backpropagation algorithm, and the gradient reflects the change rate of the loss function of the model at a certain point. Then use the optimizer to update the parameters of the model to reduce the loss function.

6) Repeat steps 3-5 until the performance of the model reaches the expectation or the training time is exhausted.

Kind of like the human brain.

From the above analysis, we can see that the big model is trying to simulate the working mechanism of the human brain. In fact, at present, human beings are the only intelligent creatures. If a large model is as intelligent as human beings, "bionic" is the best way.

Next, let’s briefly sort out the structure and working mechanism of the human brain, and then compare the structure and working mechanism of the big model with that of the human brain.

Let’s first look at the structure of the human brain.

The human brain is a neural network system composed of tens of billions of neurons, and neurons are the basic units of neural networks. Each neuron is connected with each other by synapses, which are the basic channels for transmitting information between neurons.

The core function of neurons is to receive, process and transmit information.A neuron usually consists of three parts: cell body, dendrite and axon.Neurons receive signals from other neurons and transmit them to the cell body through dendrites. The cell body processes these signals and generates output signals, which are transmitted to other neurons through axons.

The connection between neurons is usually realized through synapses. Synapses are divided into chemical synapses and electrical synapses. Chemical synapses transmit signals through neurotransmitters, while electrical synapses transmit information directly through electrical signals.

The human brain is composed of a large number of neurons and synapses, which are connected together according to specific laws to form different neural circuits and neural networks. These neural circuits and neural networks work together to complete various complex cognitive, perceptual, emotional and behavioral activities of the human body.

Through the above analysis, we can make an analogy between the human brain and various elements of the big model, as shown in the following table:

The layer in the big model can be compared with the cortex in the human brain.The layer of the large model is composed of several neurons, each neuron receives the output of the previous layer as input, and calculates it through the activation function to produce the output of this layer. The cerebral cortex is a complex network composed of neurons and synapses, in which each neuron also receives the output of other neurons as input, and transmits and processes information at synapses through chemical signals.

Neurons in the large model can be compared with neurons in the human brain.They are the basic computing units in the network, which receive input signals and process them through activation functions to generate output signals. Neurons in the human brain are the basic computing units in organisms. They connect with other neurons through synapses, receive chemical signals from other neurons, and generate output signals through electrical signals.

The parameters of the large model can be compared with the synaptic weights in the human brain, which determine the intensity and mode of information transmission between neurons. Synaptic weights in the human brain also play a similar role, which determines the connection strength between neurons and the signal transmission mode at synapses.

Quantitative comparison between large model and human brain

The above is only from a qualitative point of view, to understand the big model, the working mechanism of the human brain, and to make an analogy to their core elements.

Quantitative change leads to qualitative change, even if it is similar in structure, but the difference in quantity often leads to great difference.

Next, let’s compare the big model with the human brain from a quantitative point of view.

The following are the approximate values of the total number of neural layers and parameters of GPT-1 to GPT-3.5 models (the number of neurons is not disclosed, and GPT-4 does not disclose relevant data):

Then, let’s look at the number of neurons and synapses in the human brain. In order to make the results more referential, besides humans, we also selected monkeys, dolphins, cats and ants. The specific results are as follows:

From the above analysis, we know that the neurons of the large model can be classified as human neurons, and the parameters of the large model can be classified as synapses of the human brain. But unfortunately, the big models in the industry rarely disclose the number of neurons, but generally disclose the size of parameters. Therefore, we compare the parameter scale of GPT series large models with the synaptic scale of human, monkey, dolphin and cat brains:

From the above table, it can be seen that the "intelligence" level of GPT-3.5 has fallen within the intelligence range of monkeys, which is 285.7-2857 times worse than that of human beings.

On the other hand, from the evolution speed of GPT itself, the parameter scale can be increased by two orders of magnitude in the first two iterations, but after GPT-3, the speed of parameter scale increase is greatly reduced. Assuming that the parameter scale of GPT will increase by five times in each iteration, after five iterations (the fifth power of five is 3125), that is, GPT-9, its "intelligence level" may catch up with human beings.

Of course, the above inference is only a simple model, and there is an assumption that the intelligence level is positively related to the size of synapses (parameters). But whether this hypothesis can be established needs a big question mark.

Compared with synapses, neurons are a better indicator of intelligence. Judging from the current situation, the information processing ability of the activation function of the large model is far weaker than that of human brain neurons. The activation function of large model neurons is relatively simple. For example, the neurons of Sigmoid activation function have a smooth S-shaped curve in the output range, which can realize tasks such as binary classification, and the neurons of ReLU activation function have nonlinear modified linear properties. Relatively speaking,The neuron of the human brain is a biological cell, and its information processing ability is definitely far beyond a simple mathematical function. Therefore, even if the number of neurons in the large model catches up with the level of the human brain and reaches hundreds of billions (the corresponding parameter scale exceeds 1000 trillion), its intelligence level cannot be compared with that of the human brain.

In addition, the neural network of the large model can be compared with the neural network of the human brain, but their implementation methods are completely different. The neural network of large model simulates the connection and information transmission between neurons through mathematical model, while the neural network of human brain is a complex structure composed of neurons, synapses and other biological elements. In addition,The connections between neurons in the neural network of human brain are very complicated, and they can freely establish, dismantle and adjust the connections, while the neural network of large model is set in advance.

At present, human beings are still relatively "safe". But let’s not forget,The size of neurons in the human brain is almost constant, while the size of neurons and parameters in the large model is increasing exponentially.According to this trend, it may be only a matter of time before the intelligence level of large models catches up with human beings.

Hinton, a great god in the field of artificial intelligence, said, "The development of general artificial intelligence is much faster than people think. Until recently, I thought it would take about 20-50 years for us to realize universal artificial intelligence. Now, the realization of general artificial intelligence may take 20 years or less. "

In the face of general artificial intelligence or even super artificial intelligence, human psychology is complex. On the one hand, it is hoped that there will be more intelligent systems to help mankind complete more work and liberate productive forces; On the other hand, I am afraid to open Pandora’s box and release a monster more terrible than nuclear weapons.

I hope that even if we create a "god", it will be a god full of love, not a god who regards human beings as ants!

Commemorating the 105th anniversary of Comrade Qian Xuesen’s birth： All for the strength of the motherland.

　　editorial comment/note

　　2016 is the 105th anniversary of the birth of Comrade Qian Xuesen, a "National Outstanding Contribution Scientist". As an outstanding scientist and thinker, Qian Xuesen is not only the "two bombs and one satellite" founder of China, but also has made great achievements in the space industry, and initiated the "China School" of systems engineering, which is unique and stands tall compared with foreign counterparts. On April 24, 2016, when China’s first space day is coming, it is particularly necessary to commemorate Qian Xuesen and explore the driving force of innovation from his long-term practical experience in major engineering and colorful artistic thinking.

　　Create an immortal space monument

　　Some people say that a great man and a master come out once in hundreds or even thousands of years. As an outstanding scientist and thinker, Qian Xuesen is really a great master. Facing the needs of the country, Qian Xuesen has made five major choices in his life, and made irreplaceable contributions to the world anti-fascist war during his stay in the United States. As the founder of China’s "two bombs and one satellite", his great achievements in the aerospace industry are a monument in the rejuvenation of the Chinese nation, and the idea of system engineering and general design department he pursued all his life has promoted the development of human science and technology. Compared with foreign counterparts, China School of Systems Engineering initiated by Qian Xuesen is unique and stands tall. All these are inseparable from Qian Xuesen’s firm Marxist belief, solid theoretical foundation, rich scientific and technical knowledge, long-term practical experience in major projects and colorful artistic thinking. Today, the trend of world multipolarization and economic globalization is deepening, and the information society is developing rapidly. We feel the brilliance of Qian Xuesen’s philosophy more and more, and see the strong vitality of system engineering.

　　Qian Xuesen always combined his personal ideal with the destiny of the motherland, and he transferred from railway engineering to aviation engineering interdisciplinary; Cross-regional travel from China to the United States to study; Transfer aviation theory from aviation engineering across disciplines; Cross-domain entry into new and cutting-edge fields such as rockets, missiles and engineering control. These rich experiences enabled him to gradually improve his ideological system in the process of continuous integration and transformation, laying the foundation for presiding over China’s space industry.

　　Qian Xuesen shoulders a special mission in the struggle of the space industry. He is both a planner and an implementer. He is both a leader and a teacher. He led the astronauts to make the impossible possible, shaping another milestone in his life, and it was China’s space industry that provided a practical soil for Qian Xuesen’s system engineering thought. As Yu Jingyuan, a researcher at the former 710 Institute of Space, said: "Qian Xuesen pioneered China’s space industry, but also created a set of systems engineering management methods and technologies with both China characteristics and universal scientific significance."

　　Qian Xuesen applied the method of "large-scale corps fighting" of the People’s Liberation Army to the construction of national defense projects, and applied the unique democratic centralism of our party to the whole process of development, uniting all the forces that can be United to use in the cause of "two bombs and one satellite", and finally achieved success. Qian Xuesen realized that in order to engage in cutting-edge national defense technology and command such a large social labor, it is necessary to set up a department composed of high-tech scientific and technological teams with many disciplines, complete specialties and rich research experience to provide technical staff for leaders. This department is the embryonic form of the current aerospace system general design department, where an interactive and flexible management model combining unified leadership and two command and support systems has been realized.

　　In February 1962, with the approval of Marshal Nie Rongzhen, the Science and Technology Committee of the Fifth Research Institute of the Ministry of National Defense was established, with Qian Xuesen as its chairman. The establishment of the science and technology commission has enabled the party and government leaders to be alert and clear-sighted, and has an effective way to make scientific and democratic decisions. The organization form of the Science and Technology Committee has been used up to now. Not only the national defense science and technology industry system, the military scientific research and experimental units, but also government departments and companies have gradually established this organization.

　　In the late 1970s, Qian Xuesen once again returned to academic theoretical research. On the basis of in-depth summary and refinement of early space career practice, he published "The Technology of Organization and Management — — System Engineering, for the first time, clearly defined the early understanding of China’s system engineering, and system engineering began to develop rapidly in China. In order to further develop systematics, with Qian Xuesen’s personal initiative and participation, a seminar on systematics has been held in 710 Institute of the former Ministry of Aeronautics and Astronautics since 1986 (it was resumed in China Institute of Aerospace Systems Science and Engineering in 2013), and a "comprehensive integration method from qualitative to quantitative" and its realization form "comprehensive integration seminar hall system from qualitative to quantitative" have been creatively put forward, which is a concrete embodiment of Qian Xuesen’s system engineering thought in methodology. The holding of the seminar has made a solid contribution to the development of systems engineering in China. It is known as the "cradle of systems engineering in China" and shoulders the banner of systems engineering in China.

　　System engineering serves the country.

　　Qian Xuesen’s process of pioneering and establishing system science and system engineering has always been closely linked with China’s socialist modernization and the development of science and technology at home and abroad, and focused on solving major problems that some countries must solve. Therefore, Qian Xuesen’s system engineering thought not only has important theoretical innovation, but also has extremely important practical guiding significance and has made great contributions to national construction.

　　Qian Xuesen deeply felt that the overall design department played an important role in China’s "two bombs and one satellite" to achieve remarkable achievements, win glory for the country and compete for the people. Therefore, on the basis of in-depth study of the social system, Qian Xuesen combined with his extremely successful experience in the development of "two bombs and one satellite" and put forward the proposal of establishing the overall design department of the national economy in 1979 according to the design principles of system engineering. By using the method of system engineering, he comprehensively analyzed the system structure of China’s socialist construction, namely, "the construction of socialist political civilization, including democratic construction, institutional construction and legal construction; The construction of socialist material civilization, including economic construction and people’s physical construction; Socialist spiritual civilization construction, including ideological construction and cultural construction; Socialist geographical construction includes environmental protection, ecological construction and infrastructure construction. " China’s socialist construction is an open and complex giant system, which should focus on economic construction and make all aspects develop in harmony, cooperate with each other and promote each other. To this end, Qian Xuesen proposed to set up a general design department specializing in socialist construction to carry out top-level design of national construction, which was highly valued by the party and state leaders and organized special discussions. Although this proposal was not finally realized before Qian Xuesen’s death, in the new historical period, an important responsibility of the central government to set up a comprehensive deepening reform leading group is to be responsible for the overall design of the reform.

　　In June 1984, Qian Xuesen put forward the idea of developing agricultural knowledge-intensive industries by using system engineering thought and modern science and technology. Its main connotation is "based on grassland, making use of sunlight and creating wealth through biology". It is a new industry that uses systematic thinking, overall concept, scientific and technological achievements, industrial chain, market operation and cultural docking to manage desert resources, realize a virtuous cycle of "greening the desert, increasing farmers’ income and increasing enterprises’ efficiency", and link "blood transfusion" with "hematopoiesis" to create a great 21st century. Under the guidance of Qian Xuesen’s theories, Inner Mongolia has gradually formed sand industry series such as licorice, seabuckthorn and cistanche deserticola, and grass industry series such as cashmere, meat, milk, medicine and potato. On January 19th, 2008, when Comrade Hu Jintao visited Qian Xuesen, he said, "Not long ago, I visited Erdos City, Inner Mongolia Autonomous Region, and saw that the sand industry there developed very well. The processing of psammophytes has been started, the ecology is being restored, and the people’s living standards have also been significantly improved. Qian Lao, your idea has been realized. "

　　Qian Xuesen’s research in his last 30 years has applied the system engineering thought to China’s social system, such as military field, social governance, ecological environment and transportation. Now, the inheritors of Qian Xuesen’s thought have extended it to all aspects of our country’s construction and become its important guiding ideology.

　　Learn lively and make good use of it to enrich philosophy.

　　Qian Xuesen’s love for national conditions and people’s hearts strengthened his belief in Marxism. He always thinks that Marxist philosophy is the source of wisdom and scientific truth. In his letter to his friends, he said: "A Marxist will never love the people and will never be unpatriotic." "A Chinese Communist party member must adhere to Marxism–Leninism and Mao Zedong Thought, which is ‘ Persistence ’ Is correct. "

　　Qian Xuesen not only used Marxist philosophy to guide research, but also treated himself with historical materialism. He believes that missile space flight is a cause of thousands of people, and no one can do it without the leadership of the party and collective efforts. He just came back to the motherland at the right time and did what he should do. He is only one thousandth, one thousandth of this collective under the leadership of the party.

　　Qian Xuesen always tries to guide scientific research and engineering practice with Marxist philosophy. He believes that the rapid development of science and technology has enriched and deepened Marxist philosophy in the more than 100 years since Marx and Engels laid the foundation for the establishment and improvement of Marxist philosophy system, and Marxist philosophy is in a guiding position for scientific development. In his "Methodological Problems in Technical Science" published in 1957, he wrote: "In the research of technical science, we should combine theory with practice flexibly and not act rigidly. I think this flexible combination of theory and practice is the essence of dialectical materialism. "

　　In the process of studying and practicing Marxist philosophy, Qian Xuesen realized the combination of science and philosophy, demonstrated the scientific nature of Marxist philosophy with the achievements of modern natural science, and enriched the scientific connotation of Marxist philosophy. At the same time, from a philosophical perspective, he pointed out that the prospects of some major scientific and technological developments will have an impact on human society. His scientific theory embodies dialectical philosophical thinking, and his philosophical thinking has profound scientific connotation.

　　His scientific outlook and methodology not only absorbed the essence of China’s traditional culture and the most advanced scientific and technological achievements in the contemporary world, but also condensed a deep patriotic enthusiasm and a high sense of social responsibility, all for the strength of the motherland, world peace and people’s happiness. He attributed all his achievements to the party and the collective. At the conference that the State Council and the Central Military Commission awarded Qian Xuesen the honorary title of "National Outstanding Contribution Scientist" in October 1991, he said: "I think today’s science and technology is not only natural science engineering technology, but also the whole knowledge system for people to understand and transform the objective world. The highest summary of this system is Marxist philosophy. We can completely establish a scientific system and use it to solve problems in our socialist construction. " And stressed: "I want to promote this for the rest of my life."

　　Qian Xuesen’s spirit shines forever

　　From the Marxist point of view, Qian Xuesen highly summarized the development of science and technology and its great role in promoting social development, and pointed out the differences between scientific revolution, technological revolution, industrial revolution and social development, as well as their mutual connection and interaction. He believed that they were in a network and feedback relationship, and summarized the law of social development as: "Scientific revolution comes first, then leads to technological revolution, and finally industrial revolution", and industrial revolution caused a leap in social form. Qian Xuesen’s exposition on the interrelation and interaction between the four revolutions and their influence on social development enriches Marx’s viewpoint that "science and technology are revolutionary forces to promote social development".

　　In the mid-1980s, theories such as "post-industrial society", "the third wave society" and "information society" came out one after another. Qian Xuesen believes that these new things and situations need to be analyzed, generalized and summarized by Marxist philosophy, and the concept of Marxist social form should be developed. The fifth industrial revolution with global information network and multimedia technology has brought people into a brand-new era. This is "due to the promotion of the fifth industrial revolution, the development of market economy in the world, the trend of economic globalization is increasing day by day, and the world is gradually forming an interconnected big society, and no country can close its doors." And the invention of electronic computer has produced a new industry — — Information industry, which not only changed the traditional production tools and production relations, but also created people — The spiritual productivity of the combination of machine and machine. Qian Xuesen predicted that the information revolution will eventually lead to the elimination of the difference between physical and mental work from the perspective that electronic computers are tools to liberate mental work, and this prediction has been realized.

　　According to the latest progress of biological science and technology, Qian Xuesen put forward the "Sixth Industrial Revolution" in 1984, which is a great agricultural revolution with modern biotechnology as the core. By the 21st century, it will develop into a bioengineering industry with animal and plant engineering, drugs and vaccines, protein project, cell fusion and gene recombination. In his view, the Great Agricultural Revolution was caused by the industrialization of modern biotechnology. In essence, it used solar energy as energy, used biology, water and atmosphere, and formed a new knowledge-intensive industry through agriculture, forestry, grass, livestock, poultry, fungi, medicine and fish, plus industry and trade. The large-scale agriculture developed in this way, except for the different products produced, has no substantial difference with industry in production mode, and its development may eventually lead to the elimination of the differences between industry and agriculture, urban and rural areas.

　　Today, many of Qian Xuesen’s foresighted theories and viewpoints have come true. He is like a giant who travels through time and space. The longer he takes, the more he can appreciate the significance of his thoughts to the greatness of mankind. As time goes by, we feel the dazzling light of Qian Xuesen’s wisdom.

　　At present, the world economy is in the process of deep adjustment, the recovery momentum is insufficient, the geopolitical influence is aggravated, and uncertainties are increasing. The domestic reform has entered the critical period and deep water area, and the contradictions in all aspects have become increasingly prominent. We must pay more attention to the systematicness, integrity and synergy of the reform. The Third Plenary Session of the 18th CPC Central Committee made a general plan for comprehensively deepening the reform, and put forward specific reform objectives in economic, political, cultural, social, ecological civilization, national defense and army building, and opening to the outside world. Deepening the reform in an all-round way and building a well-off society in an all-round way are all complex systems engineering. Escorting the China with the idea of systems engineering will help it run more stably, faster and further.

　　Infinite loyalty to the party and great love for the motherland are the core elements and outstanding portrayal of Qian Xuesen’s patriotic feelings. Qian Xuesen always combined his personal ideal with the destiny of the motherland all his life. During his school days, he was diligent and diligent, aiming at serving the country and establishing the lofty ideal of saving the country by aviation; During his stay in the United States, he devoted himself to studying, aiming at rejuvenating the country and returning to China to serve; After a difficult return to China, he devoted himself to national defense, aiming at strengthening the country and achieving the great cause of "two bombs and one satellite"; In his later years, he was old and eager to enrich the country and devote his mind to people’s happiness. In his later years, Qian Xuesen once recalled: "Why should I take the road of returning to the motherland? I think the reason is simple — — For nearly a hundred years since the Opium War, Chinese people have been dreaming of becoming a powerful country and fighting constantly. Revolutionary martyrs sacrificed their precious lives for the sake of rejuvenating the country and the dream of strengthening the country for the descendants of the Chinese people, and their blood flooded the land of China. Personally, as a member of the Chinese people, I can only follow the footsteps of the martyrs and explore and pursue in thousands of dangers, regardless of others. "
