The flexibility of hands determines that human beings become the dominant species on this planet. Intelligent manufacturing is also inseparable from a good "hand". Nowadays, industrial robots are an extension of people’s hands. They are all-around players who can do both rough and fine work. The connection of submarine immersed pipes can be done by "super welder" with one hand; The industrial master machine for processing optical molds can be "seamless"; Is there really a "solar system" on the robot arm carrying the girder? Who is the "holy hand" to do holographic physical examination and local surgery for super water conservancy projects?

　　Welding the world super project with robots

　　Make welding more efficient, more accurate and more reliable

　　The deep middle passage has two directions and eight lanes, and the diameter of immersed tubes is larger than that of the Hong Kong-Zhuhai-Macao Bridge. Each immersed tube weighs 9,000 tons, which is equivalent to a medium-sized aircraft carrier. A submarine tunnel is paved with 32 immersed tubes, which will be a world super project.

　　In the manufacturing base of steel shell of immersed tube for deep middle passage, a new immersed tube is about to start construction, which adopts sandwich structure.

　　As the name implies, the "sandwich" structure is a giant steel shell made of two layers of steel plates, and then concrete is poured between the compartments of the two layers of steel plates.

　　However, the giant steel shells are all welded, and the total length of the weld seam of each immersed steel shell exceeds 300 kilometers. If manual welding is used, a immersed steel shell needs more than 1,000 welders, and the construction period is as long as 12 months. If all 32 pipe joints are welded manually, it is obviously impossible to finish the task on time. This time, the engineer decided to start robot welding.

　　The robot measures the size and position of the steel plate, the brain sends instructions quickly according to the data, and the laser sensor on the welding gun tracks and identifies the weld, and corrects the deviation in real time.

　　If workers come to weld, they need to weld at least 6 to 8 times, and the robot can do it in one go, which is comparable to a "super welder".Long Hanxin, Chief Engineer of Project Management Department of GK01 Contract Section of Shenzhen-China Passage Project of Guangzhou Shipyard International Co., Ltd.With the same workload, we used to need 18 welders, but now we may only need 4 welders. Moreover, the quality of robot welding is relatively stable.

　　On the dock, the manufactured immersed steel shell is being lightered onto the ship. A pipe joint, the top surface area is equivalent to the size of 14 standard basketball courts. The flatness of the giant section reaches within 4 mm, and such high accuracy is rare in the world.

　　Hydraulic turbine maintenance robot

　　Repair the 41-year-old Gezhouba.

　　Gezhouba, the first large hydropower station on the Yangtze River, will celebrate its 41st birthday in 2022.

　　The runner is the "heart" of the generator set, and the water current drives the runner to rotate, converting as much energy as possible into electric energy. During normal operation, the surface of the runner is as smooth as porcelain, but the turbulent river brings energy, and at the same time, it also brings sediment to violently impact the runner surface, leaving uneven scratches, which seriously affects the health of the runner.

　　The 41-year-old Gezhouba is about to undergo a "major operation".

　　By manpower, it takes at least 3 weeks to repair a water turbine unit, and 3.6 million kilowatt-hours of electricity will be lost for one more day of repair. This time, the task of overhaul was given to the robot.

　　The robot is installed on the inner wall of the runner chamber of the hydraulic turbine, so that it can climb along the curved surface and work among the complicated impellers. Moreover, the polishing accuracy should reach micron level, which is more difficult than the doctor’s cosmetic surgery.

　　There is no precedent in the world for robots to overhaul large hydraulic turbines in situ. We will wait and see how the first generation of maintenance robots for hydraulic turbines perform.

　　In 2 hours and 20 minutes, the robot repaired two inner walls of nearly 1 square meter. The approval shows that the repetitive positioning accuracy of the robot reaches 0.06 mm, and the roughness of the machined surface is less than 1 micron, which is three times higher than the requirement.

　　In a narrow space, the robot is like a climbing Spider-Man, which can easily complete the maintenance of the inner wall and top blades of the runner. A robot can complete the maintenance work of 10 people in a week in 24 hours.

　　On May 18, 2022, the maintenance of the runner was completed, 30 days ahead of schedule. Intelligent solutions have given Gezhouba a new vitality.

　　Five-axis CNC machine tools are flowing.

　　Carve an electric guitar on the tip of a pencil

　　An optical mold part with a machined surface accuracy of micron level and a surface roughness of less than Ra10 nm can not be manufactured in batches by human hands, and it needs the help of precision CNC machine tools.

　　It takes nine knives to process this precision part, and each knife has a deviation of micron level, which is a small loss and a thousand miles away. It solves the problem of tool size error and is constantly approaching the highest standard in the international precision machining field.

　　The gap between the concave and convex surfaces of the workpiece is less than 5 microns, which is equivalent to one twentieth of the thickness of a piece of A4 paper, and the seam is really fit.

　　The adjusted five-axis CNC machine tool is like a pair of artists’ hands, carving a delicate electric guitar on the pencil tip with an area of only 10.35 square millimeters. Only when the axis motion accuracy of CNC machine tools reaches micron level can it be so smooth.

Fifteen years ago, the share of self-developed CNC system in domestic machine tool market was less than 1%, but now it has increased to 31.9%.

　　Domestic heavy-load robot

　　Every minute, you can complete the manufacture of the rear side panel of a car.

　　In the automobile factory in Wuhu, Anhui Province, 26 domestic heavy-duty robots are producing the rear side panels of automobiles. The wrists of these robots can carry 210 kilograms. They can accurately grab, feed and automatically identify the welds for welding, and can complete the manufacture of the rear side panels of a car every minute.

Today, about one-third of the world’s industrial robots are used in automobile factories. However, looking at 120 automobile factories in China, more than 90% of robots are imported from abroad. If it cannot be controlled independently, it will have a far-reaching impact on the whole industry, and domestic researchers should make up for this link.

　　Accuracy is the most difficult thing for a heavy-load robot to overcome. Today, the repetitive positioning accuracy of this 210kg heavy-load robot has reached 0.072mm, which is a step closer to the international first-class standard of 0.06mm..

　　There are hundreds of enterprises that produce industrial robots in China, but there are no more than 10 domestic companies that can mass-produce large-load multi-joint robots of more than 100 kilograms.

　　Heavy-load robot is a mountain that China robot enterprises need to climb urgently.

　　Accuracy retention reaches 0.3 arc minutes.

　　Chinese can finally produce a high-precision RV reducer.

　　In industrial production, robots that can take the lead often need to bear more than 50 kilograms, and the elbow joints of these pillars must use RV reducers with greater loads.

　　The annual output of industrial robots in China has reached 440,000. However, for a long time, 70% of RV reducers are foreign brands.

　　In 2015, Zhang Yueming, a professor at Beijing University of Technology, decided to challenge this domestic blank technology.

　　Turn on the RV reducer, which is like a solar system, with both sun gear and planet wheels. This is the cycloidal planetary gear of RV reducer. They are like planets around the sun, which have both rotation and revolution. They make 40 revolutions at the same time, and realize precise transmission through multiple planetary movements, which reduces the high-speed rotation of the motor and increases the torque to drive the robot arm to rotate.

　　After tens of thousands of times of repeated optimization, a unique design method of cycloidal planetary gear modification has been formed, which ensures that the profile errors of 39 tooth profiles are controlled within 4 microns.

　　After 100,000 tests, the accuracy retention of RV reducer reached 0.3 arc minutes, which completely solved the serious wear problem. Chinese can finally produce a high-precision RV reducer after crossing the rigorous micron manufacturing.

　　"China manipulator" stunning space

　　Cool as transformers

　　On November 17, 2022, the Shenzhou 14 astronaut went out to perform the mission. This is the first extravehicular activity after the T-shaped configuration of China Space Station is completed.

　　Working closely with the three astronauts are two "magic" mechanical arms.

　　The big robotic arm is called "Tianhe Robotic Arm", and its bearing capacity can reach 25 tons, so it can be called "Hercules" of China Space Station.

　　The small robotic arm is called "the robotic arm that asks for heaven". Although its bearing capacity is only 3 tons, it is very flexible.

　　Tianhe manipulator has two arms and seven movable joints, and its deployment length is 10.2 meters. Such a long manipulator must cover all working areas in zero gravity environment, and its accuracy must be less than 5 cm.

　　When the R&D team was at a loss, an engineer drew with compasses and was suddenly inspired. Just like compasses, they also let the two hands of large robotic arms act as "feet" and act as fulcrums for each other, alternately switching forward to realize crawling and transferring.

　　Young China engineers, who broke away from convention and made innovations, made Tianhe’s robotic arm perform tasks with a precision of millimeter, and accomplished the grasping of Tianzhou’s cargo cabin and the on-orbit indexing of the cabin. They were called "ever-changing King Kong" by netizens.

China’s research and development of space manipulator is 40 years behind the world’s, but the speed of our progress has amazed the world.

　　Core reading

　　From July 1st, Hainan’s duty-free shopping policy for outlying islands ushered in a major adjustment. In addition to increasing the duty-free shopping quota for outlying island passengers to 100,000 yuan per person per year, and canceling the duty-free quota of 8,000 yuan for a single product, the number of products restricted by a single purchase has also been greatly reduced.

　　The adjustment of the new policy will fully release the policy dividend of Hainan as the first free trade port in China. In addition, around the tourist experience, Hainan will further improve the consumption and tourism market, and constantly explore for building an international tourism consumption center.

　　On July 1st, the new policy of duty-free shopping in Hainan’s outlying islands was officially implemented on the occasion of the full moon of the promulgation of the Overall Plan for the Construction of Hainan Free Trade Port. This adjustment is regarded as the biggest adjustment since the implementation of this policy, whether it is the substantial increase in the amount of duty-free shopping, the cancellation of the restrictions on the number of times of shopping, the restrictions on the amount of duty-free items for single items, and the substantial reduction in the types of goods limited by the number of purchases at one time.

　　What new changes can the adjustment of duty-free shopping policy on outlying islands bring to Hainan tourism? At the moment when Hainan is building a free trade port, the tax exemption policy for outlying islands has been implemented for nearly 10 years. What new opportunities can it bring to the construction of an international tourism consumption center? The reporter conducted an interview.

　　Small excitement: If it is inconvenient to go abroad, I will come to buy buy to buy it.

　　For some people who like shopping abroad, it is inconvenient to go abroad during the epidemic prevention and control period, so shopping in Hainan has become the first choice.

　　Xiao Meng, a citizen of Guangzhou, flew to Haikou in the early morning of July 1, which was aimed at the newly adjusted duty-free shopping policy for outlying islands.

　　In the duty-free shop located in Haikou Riyue Square, a high-end watch with a price of 17,000 yuan needs to be taxed at a rate of 50% for the part that exceeded the limit of 8,000 yuan. "Under the new policy, you can buy it for 17,000 yuan, saving more than 4,000 yuan, and the ticket money from Guangzhou to Haikou is earned back." Xiao Meng said happily.

　　At 14: 00 on July 1, the reporter went to the duty-free shop in Riyue Square, Haikou. Despite the hot weather, the citizens and tourists who came to shop were enthusiastic. The most lively counters are electronic goods counters such as mobile phones and tablet computers. A staff member of a popular brand counter told the reporter that due to the fear of a rush to buy today, the store specially put a reminder on the counter that "mobile phone products are limited to one per person at a time" when stocking.

　　"The annual shopping quota per person has been raised from 30,000 yuan to 100,000 yuan, and the restrictions on shopping times have been relaxed. This policy adjustment will undoubtedly make the market a little excited." Cao Ying, director of the Supervision Department of Hainan Free Trade Office, said.

　　In fact, such a little excitement has already appeared at the beginning of this year. On February 20th, duty-free shops in Hainan resumed business. The next day, the e-commerce sales of Sanya International Duty Free City reached 44.28 million yuan, setting a record for one-day e-commerce sales. In May, sales of duty-free goods in Hainan reached 1.977 billion yuan, a year-on-year increase of 147.9%.

　　"Adjusting the duty-free shopping policy for outlying islands can promote the quality and efficiency of Hainan’s tourism, from eating, living and traveling to shopping and entertainment, and attract consumption abroad to return." Liu Feng, director of China Characteristic Free Trade Port Research Center of Hainan Normal University, analyzed.

　　Intensity: the tax-free limit of 8000 yuan for a single commodity is cancelled.

　　In addition to the annual duty-free shopping quota of 100,000 yuan, the most striking of the relaxation measures is the cancellation of the duty-free quota of 8,000 yuan for a single commodity.

　　Statistics show that the number of shoppers in Hainan’s tax-free year increased from 483,600 in 2011 to 3.84 million in 2019, and the annual sales increased steadily from 986 million yuan in 2011 to 13.6 billion yuan in 2019. In 2019, the number and amount of duty-free goods sold in Hainan Island reached record highs, with year-on-year growth exceeding 30%. Hainan’s foreign trade import and export was 90.59 billion yuan, up 6.8% year-on-year, and consumer goods became the number one imported commodity in Hainan.

　　"For tourists to Sanya, 7 out of 10 people will go to Sanya International Duty Free City ‘ Punch in ’ 。” Su Yi, deputy general manager of Sanya Duty Free Shop, China Duty Free Goods (Group) Co., Ltd., said that this ratio fully shows that duty-free shopping on outlying islands has boosted tourism. As the only company franchising duty-free shopping on outlying islands, China Free Group ranks fourth in the global industry from 12th seven years ago.

　　However, if we compare Japan and South Korea, there is still a clear gap in Hainan. According to the data, in 2019, the duty-free consumption of Korean tourists to China was as high as 105.8 billion yuan, of which the consumption of ordinary tourists was 37 billion yuan. "The sales of Hainan Island tax exemption of more than 10 billion yuan a year is actually not high." Su Yi believes that the attraction of duty-free shopping on outlying islands to most tourists has not yet reached "coming to Hainan for the purpose of duty-free shopping".

　　Liu Feng suggested that we can increase the number of duty-free shopping spots in urban areas and use information technology to achieve flexible and effective control, from the current "management of people and goods" to "management of people regardless of goods" and "supervision in advance" to "supervision after the event" to provide a more convenient and humanized shopping experience.

　　According to Cao Ying, at present, Hainan is striving to introduce cross-border e-commerce as the first step, and gradually expand from online shopping to offline stores. At present, cross-border e-commerce can operate more than 1,000 kinds of goods, which basically cover the daily needs of residents.

　　Make up the shortcomings: tourism supporting facilities still need to be improved

　　Faced with the problems that some domestic tourists have reflected that Hainan’s tourism experience is not cost-effective, and prices and accommodation consumption experience need to be improved, Liu Feng believes that "in terms of consumption environment, there is still a big gap between Hainan and some developed tourist areas. But this is a systematic project, and Hainan is stepping up its efforts to make up for shortcomings. "

　　"In the past, many tourists complained about Sanya Hotel’s ‘ High-priced room ’ . In fact, chain brand hotels adopt a global unified pricing strategy. Compared with Southeast Asia, our overall house prices are not much different, mainly because our high comprehensive prices lead to higher travel expenses, and seasonal changes are obvious, and prices change greatly. " Tang Sixi, researcher of Sanya Tourism Bureau, said.

　　In Liu Feng’s view, the adjustment of duty-free shopping policy on outlying islands is only a breakthrough to promote Hainan to build an international tourism consumption center. "Whether the international tourism consumption center can be built depends on how Hainan’s own business environment and tourism consumption environment are built."

　　At present, the Haikou International Duty Free City project with a total investment of more than 10 billion yuan is being accelerated. After completion, the total area is 200,000 square meters, which is three times that of Sanya International Duty Free City. It is a landmark project of Hainan International Tourism Consumption Center.

　　Zhou Ting, president of VIP Research Institute, believes that the implementation of tax exemption policy for outlying islands is very important for the construction of Hainan International Tourism Island. As the first free trade port in China, Hainan can try to open up to a greater extent and form a high-quality consumer goods market to attract tourists to spend in Hainan. At the same time, all kinds of entertainment and leisure activities and services on the island should be fully developed in order to truly become an international tourism consumption center.

　　Xinhua News Agency, Shijiazhuang, May 13th-Direct roll call, hit the nail on the head. Central Environmental Protection Inspector Group stationed in Hebei. From the opening of a report phone to an unannounced visit to the front line; From the inspector to the inspector, to the centralized feedback; From handing over the problem to taking out the rectification plan within a limited time … … A series of unusual "bright swords" have triggered waves of strong impacts in Hebei and spread to the whole country.

　　Thunder and sword pierce a batch of polluted pustules

　　Air pollution is prominent, and the air quality of many cities ranks in the bottom ten in the country all the year round; Nearly a quarter of the water bodies are inferior to Grade 5; Serious pollution and degradation of ecological function in rural areas … … With the heavy industrial structure and extensive development for many years, the "water, land and air" in Hebei, a capital city province, has been polluted three-dimensionally. The first pilot of the Central Environmental Protection Inspector was stationed in Hebei. According to the feedback on May 3rd, the reporter made a field visit.

　　↑ This is the sewer in Hutuo River, Xing ‘an Town, Gaocheng District, Shijiazhuang City, which was shot on April 27th. Xinhua News Agency reporter Yan Yushe

　　— — Hutuo River is the key river in Haihe River Basin, which flows through Shijiazhuang, Hengshui and other places. At the junction of Gaocheng and Wuji, the color of sewage in the river ditch is like ink, and the soil beside the ditch is dyed dark black, with an unusually pungent smell. A villager who is watering the land nearby said that sometimes the water pumped up is yellow flowers with green foam, which can drown the crops.

　　↑ This is Wu ‘an Yuhua Iron and Steel Company named by the feedback from the Central Environmental Protection Supervision Team (photo taken on May 10th). Xinhua News Agency reporter Wang Minshe

　　— — Wu ‘an, a major iron and steel town in southern Hebei Province, on the road leading to the urban area, large trucks entering and leaving the iron and steel plant filed in succession and were dusty. Yuhua iron and steel company, located near Chongyi village, is full of white smoke, and the factory is full of coils of wire rods. The surrounding villagers love and hate the steel mills. This company was directly named by the Central Environmental Protection Inspector Group for violating regulations by building or continuing steel projects.

　　↑ This is Handan Xinxing Casting Pipe Company named by the feedback from the Central Environmental Protection Supervision Team (photo taken on May 10th). Xinhua News Agency reporter Wang Minshe

　　— — In addition to private enterprises, there are also state-owned Hegang Group Tangshan Iron and Steel Company and Handan Xinxing Cast Pipe Company. According to the reporter’s investigation, last year, Tangshan Iron and Steel Co., Ltd. undertook the task of reducing ironmaking capacity, and needed to tear down a large blast furnace and build a small blast furnace in a different place. During the inspection of the Central Environmental Protection Inspector Group, the steel projects built in different places were not put on record and hit the "gun".

　　— — Four ferroalloy projects in Tangshan failed to complete capacity substitution and illegally added capacity. According to the reporter’s investigation, the three projects of Nickel Gold Industry, Dingxiang Manganese Industry and Ganyi Industry have been put on record and capacity replacement procedures, but they have not been really implemented. The 80,000-ton nickel-iron alloy project of Tengda Technology in Caofeidian Development Zone has neither been put on record nor capacity replacement.

　　The water quality of some rivers has deteriorated obviously, steel production capacity has been built illegally, projects have been approved illegally, the problem of "scattered pollution" has been concentrated, the pollution control of loose coal has been slow, the equivalent substitution of coal has been falsified, the quality control supervision of oil products has become a mere formality, the steel mills are still being eliminated, the sludge waste from tannery enterprises has been piled up for a long time, a large number of villas have been built in drinking water source protection areas, and the ecological damage caused by dust pollution from mining has been serious … …

　　After 36 days of unannounced visits, the Central Environmental Protection Inspector Group assigned 31 batches of 2,856 environmental problems to Hebei, directly named 28 enterprises, and received nearly 10,000 words of feedback. The wording was harsh and outspoken, and the "pustules" of pollution were punctured one by one. Up to now, all the environmental problems assigned by the Central Environmental Protection Inspector Group have been settled, and Hebei will also investigate and deal with 13,784 illegal projects identified by the environmental protection inspection in combination with the requirements of the inspectors for rectification.

　　Hit the nail on the head and hit the "focus" of severe carbuncle

　　The Central Environmental Protection Inspector Group pointed out that "the phenomenon of emphasizing development and neglecting protection is more common in some places". The reporter learned that many enterprises choose the latter because of the problems involved in pollution control, such as reducing production capacity, shutting down enterprises, resettling personnel and increasing investment in environmental protection.

　　Jiajing Glass Co., Ltd., located in Shahe City, Hebei Province, was named by the Central Environmental Protection Inspector Group because of "inconsistent batch construction". The reporter learned that this company stopped production during the Spring Festival due to the unstable operation of environmental protection equipment. Li Zongkui, deputy general manager of Jiajing Glass Co., Ltd. said that the two glass production lines of the enterprise all used natural gas. Due to the increase in gas prices last year, the net loss per day was nearly 400,000 yuan, and the enterprise switched to burning heavy oil with lower cost, resulting in continuous emission data exceeding the standard.

　　"It turns out that pollution control is like slapping. This time, I feel that the knife is really on my neck." Li Zongkui said, "If environmental protection is not up to standard, it will die miserably." In order to resume production as soon as possible, the company newly invested 30.8 million yuan, and is currently upgrading its technology.

　　↑ The staff took samples from the sewage treatment tank of Hongsihai Leather Co., Ltd. in xinji city, Hebei Province (photo taken on May 10). Xinhua News Agency reporter Yan Yushe

　　Xinji city Hongsihai Leather Co., Ltd. was notified that hazardous waste was not treated in time. There is only one qualified chromium-containing sludge treatment enterprise in Hebei, which saves enough for one car and then transports it at a lower cost. There is also selfishness. After storing for a long time, the water evaporates, and the treatment fee can be twice as bad. "In the past, we thought we had made great efforts in environmental protection, but we were still named, which shocked us a lot." Zhu Xinyong, vice president of the company, said, "The leather production circle is very small, and being named has an impact on the company’s reputation. If enterprises do not eliminate pollution, pollution will eliminate enterprises. "

　　Shenzhou City was named for "the main leaders of the municipal government illegally interfered with the project approval". The main leaders of the Shenzhou Municipal Committee told reporters: "In the past, we thought that introducing big projects and good projects and promoting economic development meant benefiting the people. Now I deeply realize that the environment is people’s livelihood and it is a greater political achievement. "

　　During the reporter’s visit, some grassroots cadres said that in the past, environmental protection work was a "raw meal", and there was no hurry in the middle. Now it is from provinces, cities and counties to villages, and the pressure is only increasing. Now the county party secretary directly focuses on the rectification of an enterprise, which has become the normal state of grassroots environmental protection work.

　　↑ The embankment of Hutuo River in Nandazhang Village, Gaocheng District, Shijiazhuang City is full of garbage (photo taken on April 26). Xinhua News Agency reporter Yan Yushe

　　Four egg tray factories in Huang Zhuang Village, Gaocheng District, Shijiazhuang were reported to the Central Environmental Protection Inspector Group for pollution. Dai Shengjie, director of environmental protection in Jiumen Township, pointed to the empty factory building of Samsung Egg Tray Factory, saying that before the central environmental protection inspector group moved in, the environmental protection department had taken measures to ban this enterprise, but it failed to meet the requirements of water cut, power cut, product cleaning, raw materials cleaning and equipment cleaning, so a township cadre and a district environmental monitoring staff were held accountable.

　　"This is a wake-up call for us. Our work standards are still far from the requirements of our superiors." Meng Qinghua, director of Gaocheng District Environmental Protection Bureau, said.

　　Constantly shining the sword will lift the national supervision "storm"

　　The wording of the inspector’s feedback severely pointed out that Hebei did not pay enough attention to the strict implementation of the environmental protection work, and the work pressure was attenuated in the transmission; The problem of launching projects in violation of laws and regulations is outstanding; Some key tasks are not promoted strictly; The environmental quality in some areas has deteriorated sharply.

　　We have carried out the central government’s decision-making and deployment on ecological construction and environmental protection without any conditions or reasons, and tackled the symptoms and the root causes together, and together with prevention and rectification, a tough battle has been launched in Hebei.

　　The heavy industrial structure and coal-fired energy structure are the "culprits" of serious air pollution in Hebei. In this regard, Hebei Province made it clear that it will unswervingly resolve the excess capacity, and the party and government leaders who illegally build new steel projects or suspend the resumption of production of steel equipment will be dismissed first and then investigated and dealt with. In response to the inspector’s feedback, the steel construction project of Tangshan Iron and Steel Group was put on record at the end of April. Moreover, Hegang Group promises to be a "pioneer" and reduce the ironmaking capacity by 2.6 million tons and steelmaking capacity by 5.02 million tons this year and next.

　　↑ This is the sewage drainage canal close to vegetable fields in Hutuo River, Xing ‘an Town, Gaocheng District, Shijiazhuang City, which was shot on April 27th. Xinhua News Agency reporter Yan Yushe

　　At the same time, a series of special actions to control environmental pollution such as air, water and soil have also started. A number of environmental protection systems, such as accountability for leading cadres’ assessment and grid management of environmental protection, are being established and improved. Hebei will also take the lead in launching the provincial environmental supervision system and the vertical management reform of environmental monitoring, supervision and law enforcement below the provincial level.

　　At present, although the inspection work of the Central Environmental Protection Inspector Group in Hebei has come to an end temporarily, the powerful shock wave brought by the "environmental storm" is being pushed to the whole country.

　　The reporter learned that inspections in about 15 provinces will be completed this year, and full coverage will be achieved in 2017. At the same time, the Ministry of Environmental Protection requires the environmental protection departments of all provinces (autonomous regions and municipalities) to carry out comprehensive inspections of more than 30% municipal governments this year and strengthen environmental supervision. By 2020, all provinces (autonomous regions and municipalities) will complete a round of comprehensive environmental protection inspections of municipal and county party committees and governments and their relevant departments.

　　"This storm of environmental protection inspectors has alerted people and clearly felt the impact of environmental protection inspectors. Enterprises from other provinces have already had environmental pressure and survival crisis." Pei Peihua, deputy mayor of Shahe City, who is in charge of environmental protection, said that he often receives calls from other places to consult pollution control experience. "On environmental protection issues, whoever is lucky is a dead end."

　　Public opinion believes that in the face of the central environmental protection inspector who will come sooner or later, instead of passively waiting for the problem to be found out, it is better to actively investigate the problem, face the problem squarely, solve the problem ahead, and resolve the contradiction ahead.

　　　　　　 CCTV News:According to Korean Central News Agency’s report today (No.2), Kim Jong-un, the top leader of North Korea, recently inspected the textile and chemical fiber factories in Sinuiju, which is near the border between North Korea and China. During the inspection, Kim Jong-un also repeatedly criticized the relevant factories.

　　　　　　 According to reports, during the inspection, Kim Jong-un said that realizing the epoch-making development of the textile industry is of great significance for opening a breakthrough to improve people’s livelihood. After learning that the factory has been put into production since 1959, but now it is unable to complete the national economic plan, Kim Jong-un expressed his sadness and criticized the factory party Committee for not caring about improving the working and living conditions of employees. Kim Jong-un proposed that the production process should be scientific and modernized next year, and at the same time, the factory should be rebuilt and renovated so that the factory can contribute to improving people’s livelihood.

　　　　　　 Kim Jong-un also inspected the papermaking workshop of Sinuiju Chemical Fiber Factory, and said that it is necessary to revitalize the papermaking industry, ensure educational paper, demand to improve the quality and output of paper, and severely criticize the factory cadres for failing to do their duty to ensure the modernization of production processes.

　　　　　　 It is rare to criticize the inspected enterprises in succession during the inspection in North Korea’s reports. From the focus of the report, the two inspections, one focusing on improving people’s livelihood and the other focusing on ensuring education, also correspond to the new policy line put forward at the Third Plenary Session of the Seventh Central Committee of the Workers’ Party held in April this year. However, successive criticisms show that North Korea attaches importance to economic development and urges North Korean enterprises that fail to meet the production targets according to the five-year plan.

　　　　　　 Earlier, Kim Jong-un also inspected Sinuiju Cosmetics Factory and Sejima County, North Pyongan Province.

Monopterus albus is a seasonal food in Jiangsu and Zhejiang provinces in summer.

On the Dragon Boat Festival, people in the northwest love noodles with minced meat more.

　　Text/Figure Yangcheng Evening News reporter Song Wei Intern Tu Xinyi

　　Egg yolk dumplings, fresh meat dumplings and red bean paste dumplings … … When it comes to Dragon Boat Festival cuisine, Zongzi must be a well-deserved protagonist. However, many health experts believe that not everyone is suitable to eat zongzi. Because glutinous rice is sticky and stays in the stomach for a long time, people with stomach diseases should try to eat less. In fact, apart from Zongzi, there are many kinds of Dragon Boat Festival foods in many places in China … …

　　Jiangnan eats "wuhuang" for good luck.

　　In the south of the Yangtze River, which is known as the land of plenty, people have the custom of eating "wuhuang" during the Dragon Boat Festival. There is a nursery rhyme in Jiangnan folk: "Duanyang Festival, eat wuhuang; The door is full of incense; Eat zongzi and dip in sugar; Five tigers in the sky are king. " The so-called "wuhuang" refers to yellow croaker, cucumber, salted egg yolk, eel and realgar wine. Among them, Monopterus albus is a representative summer food in Jiangsu and Zhejiang.

　　It is reported that eel is the fattest and most delicious from June to August every year. Monopterus albus not only tastes good, but also has a particularly high nutritional value.

In today’s digital age, electronic invoices are widely used in insurance business. Understanding the inquiry methods and related operations of electronic invoices not only facilitates the insured to manage their finances, but also protects their own rights and interests. The following will introduce the electronic invoice inquiry method and the connection between related operations in detail.

There are usually two ways to query electronic invoices: online and offline. Online inquiry is the most convenient way at present. Common channels include the official website of insurance companies, mobile apps and third-party electronic invoice service platforms. Offline inquiry requires the insured to go to the business outlets of the insurance company and assist in the inquiry through the counter service personnel.

Take online inquiry as an example. To inquire about electronic invoices on the official website of an insurance company, the insured needs to log in to his account first. If you have not registered, you need to register first and complete real-name authentication. After logging in successfully, find the "Electronic Invoice Inquiry" entry in the relevant functional modules of the website, enter the necessary information such as invoice number and billing date according to the system prompt, and click Query to obtain the electronic invoice. The operation process of querying on the mobile APP is similar. Generally, the electronic invoice query function can be found in the menu bar on the homepage of the APP. The third-party electronic invoice service platform requires the insured to confirm that the platform has a cooperative relationship with the insurance company, and then register and log in on the platform, and inquire after associating their own insurance order information.

Although offline inquiry is relatively troublesome, it is a reliable choice for policyholders who are not familiar with online operation. When going to the insurance company’s business outlets, the insured should bring valid identity documents and insurance contracts to explain the requirements to the counter service personnel, who will query the electronic invoice in the system according to the information provided and provide the corresponding paper or electronic version.

The electronic invoice inquiry method is closely related to related operations. The inquiry method provides the direction for the operation, and defines the ways to inquire about electronic invoices. The specific operations are the specific steps to realize the inquiry method. Only by correctly executing these operations can the electronic invoice be inquired smoothly. For example, if you know that you can query the electronic invoice on the official website of the insurance company, you will not be able to complete the query if you don’t know how to log in the account number and enter the query information.

In order to compare the characteristics of different query channels more clearly, the following is a simple table:

When inquiring about electronic invoices, the insured should choose the appropriate inquiry method and operation mode according to their actual situation. At the same time, it is necessary to properly keep the electronic invoices so that they can be checked and reimbursed when necessary.
