　　On May 5, 2017, people with big plane dreams came to a small slope outside the fourth runway of Shanghai Pudong International Airport early, waiting for the exciting moment. On this day, it was the first flight day of C919, a large jet passenger plane independently developed by China, and the small earth slope outside the runway was affectionately called "Wangjiupo".

　　With the roar of the engine, the first C919 large passenger plane, piloted by captain Cai Jun and co-pilot Wu Xin, took off from the fourth runway of Pudong International Airport at 14: 00, rushed into the sky, and landed successfully 79 minutes later. After nine years of scientific research, numerous tests and technical debugging, there is once again the shadow of domestic large aircraft in the blue sky, which indicates that China has entered the ranks of a few countries with the ability to develop large passenger aircraft.

　　Now, more than two years have passed. What’s the progress of airworthiness certification of C919 passenger plane? When can Chinese get on a large domestic plane? Recently, the reporter came to China Commercial Aircraft Co., Ltd. for a field visit.

　　Yun -10: Leaving an innovative gene is an attempt to commercialize domestic aircraft.

　　Arriving at the Pudong base of China Comac Shanghai Aircraft Manufacturing Co., Ltd., I saw a large plane with a white fuselage and several blue and white stripes sleeping peacefully on the lawn of the industrial park, with a bright red flag on its tail. This unique large passenger plane in the world soared in the blue sky of China more than 30 years ago, and its name was Yun -10.

　　Boarding the Yun -10 plane, the reporter was shocked by the industrial level at that time. The throttle lever, pedals, various instrument panels and indicator lights in the cockpit are reasonably arranged and fully functional. In addition to the seats for the main driver, the co-pilot and the pilot, there is also a seat for the mechanic. When the aircraft breaks down in flight, the mechanic can go down to the inside of the aircraft from the passage next to the seat for maintenance. When you come to the cockpit, the passenger seat is no different from the common big plane now, except that the distance between the front and back of the seat is larger, the ride experience is more comfortable, and there is an ashtray on the armrest.

　　In August 1970, with the approval of Comrade Zhou Enlai, the state agreed that the report on trial production of transport aircraft in Shanghai should be centralized by the Ministry of Aviation Industry. The mission name is "Project 708" and the aircraft code is "Yun -10". According to statistics, at that time, more than 300 factories, research institutes and universities in 21 provinces, autonomous regions and municipalities participated in the development of Yun -10 aircraft.

　　On September 26th, 1980, Yun -10 successfully made its first flight in Shanghai. Subsequently, Yun 10 flew all over the country, reaching 10 cities, including Beijing, Harbin, Urumqi, Guangzhou, Kunming, Chengdu, Hefei and Zhengzhou. The longest time for a single flight was 4 hours and 39 minutes, and it completed a scientific test flight that flew over 3,600 kilometers in 3 hours and 42 minutes. Its performance and use characteristics fully met the design requirements. Yun -10 also flew over the Himalayas to Tibet seven times, transporting more than 40 tons of urgently needed materials for Xizang Autonomous Region.

　　Although the Yun -10 aircraft project was not officially put into commercial use for various reasons, the Yun-10 spirit of "independence, strong cooperation, selfless dedication and continuous innovation" has been passed down from generation to generation by large aircraft people.

　　Next to the lawn where Yun -10 plane docked, there stands a sculpture engraved with the four characters "Never give up", which is a solemn promise from the heart of the big plane people and the earnest expectation of hundreds of millions of people for the early commercialization of domestic big planes.

　　Time has entered the new century. In February 2000, the state decided to support the production of domestic civil aircraft and accelerate the development of regional air transport. In June, 2002, the State Development Planning Commission issued a document officially approving the establishment of the new regional aircraft project. The result is a new turbofan regional plane that has soared in the blue sky of China today — — Arj21 (advanced regional jet for 21st century) means advanced jet regional aircraft in the 21st century. ARJ21-700 is its basic model, and it is the first time that China has developed and produced regional aircraft in strict accordance with the internationally accepted regulations on aviation airworthiness management.

　　ARJ21: Delivered the 21st aircraft, accumulating valuable experience for the civil aircraft industry.

　　Not long ago, on November 29th, Comac China delivered the 21st ARJ21-700 aircraft to its customers. Talking about the differences between civil airliners and other aircraft, Ye Chao, deputy director of ARJ21 Division of China Comac Shanghai Aircraft Manufacturing Co., Ltd., has a lot to say: "The independent development of a jet regional aircraft needs to go through the processes of design, trial production, test flight, evidence collection, production, etc. This is not all. To make the aircraft truly commercialized, it must be tested by the market. If the requirements of airlines cannot be met, the cost performance ratio is low, and the experience of drivers, flight attendants and passengers is poor, the mission of the aircraft will not be truly completed. "

　　In the process of design and development, the ARJ21-700 aircraft has fully considered the number of seats, comfort and the needs of the aviation market in western China. Compared with similar aircraft, the cabin of ARJ21-700 aircraft has a higher and wider cabin, the cabin height is more than 2 meters, reaching the same cabin comfort as that of narrow-body aircraft, and the cabin height is close to 1 meter, which can provide more luggage space for passengers. The economy of the aircraft is also more prominent, and the engine fuel consumption is low. In order to adapt to the complex geographical environment in the west of China, the ARJ21-700 aircraft pays attention to take-off and climb performance in design, and can take off and land in a short distance, which has a strong advantage in the adaptability of western routes and western airports.

　　Although customers’ needs were fully considered in the design and manufacture, when facing the customer representatives seriously, Comac found that there were many details to be perfected. Because, from "product" to "commodity", the difference is not just one word, but also thousands of times of self-improvement and continuous collision with customers.

　　In Ye Chao’s view, there were three "self-revolutions" on the sales road of ARJ21-700. "When we sold the plane to Chengdu Airlines for the first time, it was the first time that we delivered the plane to our customers. During the continuous running-in, we found that some problems that we had never thought of were exactly the concerns of our customers. The second time ‘ Self-revolution ’ When the plane was delivered to Tianjiao Airlines. We have changed from serving one customer to serving two customers, which requires us to be more refined in technology and operation specifications. Now we are facing the third time ‘ Self-revolution ’ New customers such as Air China, China Eastern Airlines and China Southern Airlines will put forward more new requirements for our products. In the future, we should look at production from the perspective of creating handicrafts. "

　　Since the commercial operation of the ARJ21-700 in June 2016, the optimization and improvement of the aircraft production process has been carried out almost every day. "For example, the pilot’s operation has been greatly modified to reduce the pilot’s workload; In order to reduce the noise in the engine room, the conventional sound insulation cotton material is replaced by metal damping layer and rubber sound insulation material; In order to reduce the airflow noise at the air outlet of the air conditioner, silencers are installed, and there are various optimizations for flight attendants and aircraft maintenance personnel. " Ye Chao said.

　　With more and more orders, the mass production capacity of ARJ21 has gradually improved. In 2017, it will produce 4 aircraft, in 2018, 11 aircraft, and strive to produce more than 20 aircraft in 2019. Behind the digital beat is the continuous improvement of the overall efficiency of the workstation and the efficiency of skilled workers. Comac China has continuously promoted the innovation of production management in terms of process technology, on-site management, production operation control and so on. From January to September this year, the batch production rate of ARJ21 aircraft increased by 76.9% compared with the same period in 2018.

　　The development of ARJ21 regional jet has accumulated valuable experience for the development of China civil aircraft industry. After the whole process of jet regional aircraft design, trial production, test flight, evidence collection, production, delivery and operation, China has the development capability and airworthiness certification capability of jet regional aircraft, and people have more confidence in the future of large passenger aircraft projects.

　　C919: All tests are carried out in parallel, and the test will be prepared for "evidence collection".

　　In the avionics system comprehensive laboratory of Comac Shanghai Aircraft Design and Research Institute, researchers are busy, and the indicator lights are flashing on the rows of computers. On the monitors one by one, the program codes pass by in turn, and the C919 aircraft is being tested and verified here.

　　Walking into the iron bird test-bed of C919 aircraft, the test-bed in front of us looks like an "iron bird", except that it can’t fly, and its shape and internal structure are basically the same as the real C919 aircraft, so it can be called a simulation aircraft. The integration tests of flight control, landing gear, hydraulic system, etc. are all completed here. After the command is issued from the console, Iron Bird completes the relevant specified actions, confirms and verifies that the system design meets the requirements of product development, and ensures flight safety. The international mainstream aircraft manufacturers have completed the technical verification and technical improvement of related models through the Iron Bird test bed. "In addition, it has another function: when the flight test of the C919 aircraft fails, we can simulate it through the iron bird test bed and find a solution to the failure." Li Tao, director of the construction of the State Key Laboratory of Civil Aircraft Simulation Flight of Shanghai Aircraft Design and Research Institute, said, "At present, we are intensively carrying out the airworthiness verification test of the laboratory."

　　Isn’t the C919 plane already empty? What are the researchers still busy with?

　　"We are working on the airworthiness certification of the C919 passenger plane, that is, ‘ Textual research ’ . At present, laboratory tests are being carried out here, in addition to on-board ground tests, flight tests, simulator tests and supplier product identification tests. After the success of the R&D test flight of the C919 passenger plane in 2017, it still needs several stages of test flight and airworthiness evidence collection before it can be delivered to the airlines. " Li Tao said.

　　In order to ensure the efficient ground test and flight test on board, "in October this year, 105 aircraft completed the first test flight, and the number of aircraft used for flight test will reach 6 in the future, and related flight test work is being carried out in parallel." Nan Guopeng, captain of 105 aircraft of C919, introduced.

　　Simulator tests are also being carried out in an orderly manner in Shanghai Aircraft Design and Research Institute. Boarding the C919 passenger aircraft engineering simulator, this equipment looks like a big ball, and its interior is almost the same as the real aircraft cab. Li Tao introduced: "The simulator can undertake the test tasks such as aircraft control law evaluation, cockpit evaluation and safety evaluation. At the same time, it can also undertake the training and training of test flight crews to help pilots understand aircraft performance as soon as possible. "

　　It is understood that before the C919 large aircraft is delivered for use, it is necessary to obtain three certificates, namely: type certificate (TC), indicating that the aircraft design is safe and seaworthy; Production license (PC), which indicates that the aircraft manufacturing system meets the requirements and can be produced on a large scale; Single Airworthiness Certificate (AC) proves that a single aircraft is in a safe and available state, which is equivalent to the "driving license" of a car. These work plans will take two to three years to complete. If they go well, Chinese will be able to take a large domestic plane designed and manufactured by himself in the near future.

　　In addition to the joy and pride of flying in a large domestic plane, the development of C919 has a long-term strategic significance. It is not a simple product, nor is it an ordinary commodity. The manufacture of large passenger aircraft is known as the "crown of modern industry", which plays a very significant role in driving the civil aviation industry and modern industry.

　　From the perspective of aviation industry, with Shanghai as the leader, more than 200 enterprises and nearly 200,000 people from 22 provinces and cities including Shaanxi, Sichuan, Jiangxi, Liaoning and Jiangsu participated in the development and production of large passenger aircraft projects. The China civil aviation industrial chain, value chain and innovation chain driven by the C919 large passenger aircraft have great energy, and at the same time, it has promoted the establishment of 16 joint ventures in airborne systems such as avionics, flight control, power supply, fuel and landing gear, which has promoted the civil aircraft industry in China.

　　From the perspective of upgrading the modern industrial level, a commercial aircraft consists of 3 million to 5 million parts. These parts need to be produced by thousands of suppliers, which can promote the group breakthrough of key technologies in the fields of new materials, modern manufacturing, advanced power, electronic information, automatic control, computer and many other basic disciplines. "There are many domestic suppliers involved in the parts of the C919 passenger plane, and the fuel tanks, valves and landing gear equipment of the hydraulic system are all produced in China. Through the C919 project, we have grown together with our suppliers. " Li Tao said.

　　At dusk, when leaving Shanghai Aircraft Design and Research Institute, the research building was still brightly lit. In order for the C919 to be delivered as soon as possible and soar in the sky, another night for technicians began … …

　　Interview notes

　　It takes only 4 hours and 18 minutes to get from Beijing to Shanghai by high-speed train, but it is not necessarily faster than the high-speed train, not counting the waiting time for the flight to take off and queue up. However, this reporter still chose to fly because he had a question in his heart — — When can we get on the big plane made by Chinese himself?

　　Not long ago, I was chatting with a friend. When he heard that all the large passenger planes we are taking now are foreign products, his face showed a very surprised look: "What? However, our fighter plane, the National Day military parade is so beautiful, and manned space flight has already sent astronauts out of the earth. How can we buy a foreign plane? " The reporter told him: "It won’t take long. I will definitely bring you back the latest progress when I go to Comac for an interview this time. "

　　The plane rushed into the sky and entered the stratosphere. The reporter took out the "Safety Tips" from the front seat pocket and saw that the plane on flight CA1855 was Boeing 787. Thinking of a news I just saw recently, the order for C919 large aircraft has exceeded 1,000. Maybe a few years later, the reporter will watch Safety Tips again, and the models on it will be different.

　　With countless questions, I came to Pudong base of Shanghai Aircraft Manufacturing Co., Ltd. and Shanghai Aircraft Design and Research Institute. The reporter finally knew why civil aircraft manufacturing was so difficult. What is carried on it is not goods, nor one or two people, but dozens and hundreds of lives, and there is no room for any safety problems. In addition, the performance requirements of civil aviation aircraft are also very high. During the service period, an aircraft generally has to go through 60,000 flight cycles (take-off and landing) and 90,000 flight hours, with a service life of 30 years or more. Even some seemingly unremarkable parts on the plane must be used stably and safely for decades. In order to compete with the world aviation market, the large aircraft we build must be safer, more comfortable, more environmentally friendly and more economical than others, so as to have a broad market.

　　The big plane people are working hard for all this.

　　In an interview, the reporter really felt their busyness and dedication. The interview was interrupted several times by phone calls, and the interviewee repeatedly pressed the phone for fear of influencing reporters to ask questions. When a reporter asked a researcher at Shanghai Academy of Aeronautics and Astronautics, "Are there any touching stories in your work?" He smiled and said, "It’s nothing. Everyone usually completes the test task seriously." The colleague sitting on the side couldn’t help it. She grabbed the conversation and said to the reporter, "Our researchers are really selfless. Many technical backbones are in their thirties and forties, old and young. In order to complete the airworthiness forensics work as soon as possible, they basically work overtime every day. You will know when it gets dark." Hearing this, the former researcher who said there was no story was somewhat silent. He said, "Last Friday, I got home after 10 o’clock in the evening and found that my wife didn’t let the children sleep. When I thought about it, I went out early and returned late. The child has not talked to me for a week. " These little details permeate all aspects of the interview, which is moving.

　　When leaving the interview, the reporter remembered the 16 Chinese characters hanging on the wall of the C919 assembly workshop — — Long-term struggle, long-term research, long-term hardship and long-term dedication, after the delivery of more than 20 ARJ21, the C919 will also be delivered in the next two or three years, and the CR929 wide-body passenger aircraft jointly operated by China and Russia will also start construction in the next few years.

　　Let’s look forward to it. In the blue sky, there are more and more domestic passenger planes.

　　(Reporter Zhang Pengyu finishing)

　 　 　 　 On June 19, the website of the Supervision Department of the Central Commission for Discipline Inspection announced the news of the fall of two provincial and ministerial officials in Shanxi almost at the same time.

　　　　　　　　Surprisingly, Du Shanxue, the former member of the Standing Committee of Shanxi Provincial Committee and vice governor, was robbed of all the limelight by the then vice chairman of Shanxi Provincial Political Consultative Conference, and almost no one paid attention to this native Shanxi leader.

　　　　　　　　Du Shanxue, 58, is from Linyi County, Yuncheng City, Shanxi Province. He has been an official for more than 30 years, and at every stage, he has been promoted step by step by grasping the policy direction and keeping the pulse of the times, and gradually got the evaluation of "smart people".

　　　　　　　　In the process of promotion, he used "article road" to clear the way, "image card" as a foothold, and "Zhouyi Gua" as an escort, and then acted step by step.

　　　　　　　　Until the fall of the horse, Du Shanxue was still diligent in writing political articles and making intensive public appearances. It was noticed that the tail end of his unique broom eyebrow had turned white.

　　　　　　　　After the fall of the horse, many people familiar with him reflected on his ups and downs. Du Shanxue calculated the beginning and process, but he didn’t guess his own result.

Win favor with an article

　　　　　　　　Du Shanxue’s official career began with an article.

　　　　　　　　In the late 1970s and early 1980s, at the beginning of reform and opening up, all walks of life in China were in urgent need of talents. In the spring of 1982, Du Shanxue, who graduated from the Accounting Department of Shanxi University of Finance and Economics, joined the Shanxi Provincial Finance and Trade Committee as the first batch of graduates after resuming the college entrance examination.

　　　　　　　　"’Xiao Du’ is very clever and has a good business." A colleague of Du Shanxue recalled that the young man from Yuncheng wore a pair of glasses, and he was always smiling and good at talking. He read books and newspapers when he had nothing to do.

　　　　　　　　Du Shanxue, then 26, was also trying to show his "good business".

　　　　　　　　In September, 1982, the Twelfth National Congress of the Communist Party of China was held, which put forward the financial concept of "a game of chess in the whole country", and suggested that the proportion of central and local fiscal revenues and the proportion of corporate profits should be appropriately adjusted according to the actual situation of industries in different regions. Based on the situation in Shanxi Province, Du Shanxue wrote the article "Discussion on Management of Extra-budgetary Funds" and published it in the first journal of Shanxi University of Finance and Economics in 1983.

　　　　　　　　Three months after the article was published, Du Shanxue was transferred to the third office of the General Office of Shanxi Provincial People’s Government. A veteran cadre who has been immersed in Shanxi officialdom for many years recalled that at that time, young people who could write and do things were very popular. Du Shanxue, who worked in the provincial government, is still popular because of his "agility".

　　　　　　　　Since then, the habit of "writing articles" has run through Du Shanxue’s entire political career.

　　　　　　　　According to the statistics of public information, Du Shanxue served as the deputy director of Shanxi Provincial Department of Finance for 10 years, and published more than 10 articles in 7 periodicals such as Shanxi Finance and Economics, Finance and Market, and led a team to study the topic of "Enlightenment of Shanxi Banks on Modern Financial Risk Prevention".

　　　　　　　　Since then, Du Shanxue has published three works in five years in Changzhi municipal government, seven works in three years in Changzhi city, three works in one year in Lvliang Municipal Committee, and six works in three years after becoming a member of the Standing Committee of Shanxi Provincial Committee.

　　　　　　　　"His articles always follow the political trend." A Shanxi official who knows him well said that from the 12th National Congress to the 18th National Congress, it has been a compulsory course for Du Shanxue to find the "wind direction" from policies and documents for more than 30 years.

　　　　　　　　Du Shanxue’s "topical articles on current politics" will lead the implementation time of specific policies from time to time, and most of his administrative methods are in line with the political mainstream.

　　　　　　　　In 2000, when financial departments all over the country took the implementation of government procurement system as a way to deepen the reform of fiscal expenditure management, Du Shanxue’s article "Government Procurement and Building a Clean Government" had been published for more than a year.

　　　　　　　　After "Scientific Outlook on Development" was put forward, Du Shanxue also promoted "green development" in Changzhi, trying to make Changzhi a rare city with fine features in Shanxi, a big coal province.

Smell the wind to plant trees.

　　　　　　　　According to a person familiar with Shanxi officialdom, Shanxi is a big province with coal resources, and there are few cities with "fine features". We have worked hard on the image of the city and achieved quick results in political achievements.

　　　　　　　　After Du Shanxue was in charge of Changzhi, he gradually explored this "road of political achievements". This has also become the focus of his administration during his administration of Changzhi and Lvliang.

　　　　　　　　In February 2003, Du Shanxue came to Changzhi, served as deputy secretary of the municipal party committee, and became mayor of Changzhi a month later.

　　　　　　　　At the beginning of 2003, Changzhi just sent away Lv Rizhou, a former party secretary with personal heroism. During Lv Rizhou’s three years in Changzhi, he created a unique way of governance, such as the Changzhi Daily criticized officials by name, the government did not set up a fence, and rode to the countryside. For a time, Changzhi and Lv Rizhou became an inseparable whole.

　　　　　　　　Du Shanxue, who first arrived in Changzhi, was looking for a breakthrough for himself in the post-Lv Rizhou era.

　　　　　　　　Yang Lin (not his real name), an official of Changzhi City, said that in Shanxi, Changzhi did not have the advantage of playing the economic card and eating energy meals, and Du Shanxue also made such an attempt.

　　　　　　　　Yang Lin said that Du Shanxue didn’t smoke or drink at that time, and he was preoccupied with political achievements. After the Third Plenary Session of the 16th CPC Central Committee, "Scientific Outlook on Development" came into public view. Therefore, in October 2004, Du Shanxue’s book Promoting the All-round Development of Government Work with Scientific Outlook on Development was published.

　　　　　　　　Yang Lin said that at that time, Du Shanxue only grasped the key policy points and put forward the slogan of "Green Changzhi", which was after 2005.

　　　　　　　　In 2005, Du Shanxue’s article "Harmony and Development of Building a Charming City with Strength" was published. In the article, based on the national strategic background of "the rise of central China" and the development direction of "circular economy", he proposed to inject "circular economy" into industrial development, and made predictions for the development of Changzhi according to the plans of Bohai Economic Belt, Longhai Economic Belt and the Central Plains Economic Development Circle that was not yet formed at that time.

　　　　　　　　Du Shanxue’s political sense of smell was praised again. Since then, the slogan of "Green Changzhi" has made Changzhi begin to attract attention.

　　　　　　　　"Look at so many trees in Changzhi, all of which were transplanted by Lao Du at that time." Yang Lin said that in 2006, the Changzhi Municipal Party Committee and Municipal Government issued the document "Building a First-class Forestry Ecological City in the Province". By the end of 2008, "100,000 Trees" began to enter the city vigorously.

　　　　　　　　Shanxi Evening News once reported that Changzhi invested 50 million yuan to transplant 100,000 trees into the urban area. The main tree species were Sophora japonica, willow and fatong, and their DBH was above 10 cm.

　　　　　　　　Many Changzhi citizens recalled that there were suddenly many trees in Changzhi, which made it inconvenient for them to drive. For example, because there were many trees, it was inconvenient for cars to enter and exit. Finally, these trees that occupied the place were removed.

　　　　　　　　Du Shanxue wrote a special article in 2010 to summarize the Changzhi greening project represented by "trees entering the city".

　　　　　　　　In the article, he wrote that since 2006, the Changzhi Municipal Party Committee and Municipal Government has raised 1.87 billion yuan for greening, mainly from government investment and environmental restoration and governance deposits of coal enterprises. Among them, the financial investment at the city and county levels is 1.66 billion yuan.

　　　　　　　　These investments have brought Changzhi the titles of national garden city and national forest city.

Based on "image card"

　　　　　　　　Du Shanxue, who was encouraged by the "image card", continued to maintain and expand this style, just as he got the opportunity from "making a fuss".

　　　　　　　　In June 2008, the whole country was preparing for the Olympic security, and Changzhi was no exception.

　　　　　　　　On the morning of June 5th of that year, Du Shanxue, then secretary of Changzhi Municipal Party Committee, stood on an open-top military vehicle with his feet, and slowly passed by the main road in front of Bayi Square in Changzhi City, inspecting the police and armed police teams standing on the side of the street. In his own way, he recorded the "Changzhi-style Olympic security drill".

　　　　　　　　Deng Xin (not his real name), a politician from Changzhi, who is close to Du Shanxue, said that on June 5, 2008, in order to match the national Olympic spirit, Changzhi held an Olympic security swearing-in meeting. The leaders of the municipal party committee and the municipal public security system conducted a comprehensive review of the police, fire fighting and armed police teams in Changzhi, and each team also performed their skills in anti-terrorism, riot prevention, fire fighting and traffic command.

　 　 　 　 Now, on the website of Changzhi municipal government, you can also find graphic records about this "swearing-in meeting". In the published picture, the military vehicle where Du Shanxue stood was labeled as "Reading Police Car". After the vehicle where he was standing, Bo Li, then director of Changzhi Public Security Bureau, stood in the reading police car and accompanied him with a military salute.

　　　　　　　　Later, Deng Xin looked up the information about the Olympic security drills conducted all over the country on the eve of the 2008 Olympic Games. At that time, the "Olympic security drills" held in Chongqing, Jinan, Shenyang and other places were all conducted in a relatively closed space, such as anti-terrorism and security drills. Unlike Changzhi City, the city leaders were not allowed to inspect dozens of square teams.

　　　　　　　　"Lao Du has a good face and likes to use’ form’ to express his work." Deng Xin said that Changzhi and Lvliang’s "Sweeping the City Movement" can best reflect his characteristics.

　　　　　　　　In order to enhance the image of the city, the doorways of street shops in Changzhi City should be changed into "white boxes with red (blue, yellow) background and white characters", and government units should divide regional contracting tasks and be responsible for the doorways replacement of merchants in their respective regions. Merchants only need to pay the money to the responsible person designated by the government, and the price ranges from 4000 to 7000 yuan.

　　　　　　　　Merchants specializing in this kind of billboards in Changzhi said that the billboards that the government requested to be replaced have a frame and a bottom, which belongs to the high cost of advertising doorplates. It would be more economical to find a doorplate vendor for this kind of billboards. The merchant said that the merchant who changed the house number at that time was not local to Changzhi.

　　　　　　　　Changzhi City, which pays attention to image, was rated as "National Civilized City" in 2011. It was also in this year that Du Shanxue was transferred to the post of Secretary of the Municipal Party Committee of Lvliang.

　　　　　　　　"My previous leaders of the municipal party committee have developed the economy very well, so my job is to improve the living environment for the people of Lvliang." This is what Du Shanxue said to the media when Lvliang took office.

　　　　　　　　Finding his feeling from the "image card", he launched a massive "three rectification" campaign in Lvliang, namely, environmental sanitation, street decoration and traffic order.

　　　　　　　　"Being neat and beautiful is the requirement of’ Lao Du’." A citizen of Lvliang said that at that time, doors were being torn down, plaques were being changed and walls were being painted everywhere in Lvliang Avenue.

　　　　　　　　This citizen has witnessed the discoloration of a wall several times: at first, it was painted white, then it turned gray, then it was pink, then it was ugly and changed to white, and finally it was painted gray.

　　　　　　　　An insider close to the Lvliang Municipal Government said that the "three rectifications" also emphasized accountability and publicity.

　　　　　　　　At that time, the main leaders of the urban areas and counties in Lvliang signed a written pledge to fulfill a military order, and all units took the lead in the environmental remediation activities in the contracted areas. Due to the ineffective actions of the "three remediation", Lvliang City also punished many county-level cadres, and Du Shanxue was called the "sweeping iron hand" secretary locally.

　　　　　　　　In July, 2011, Lvliang also held a live observation meeting on "Three Remedies" in Shanxi Province, inviting the media to visit.

　　　　　　　　According to a media person who participated in the report at that time, Du Shanxue attached great importance to the media propaganda of "three rectifications" in Lvliang. When having dinner with reporters, he specially got up and toasted one by one, encouraging reporters to "write Lvliang skillfully".

　　　　　　　　However, in view of the "three rectifications" activities in Lvliang, some people in the legal profession have publicly questioned in the "Democracy and Legal Times" that in the process of "three rectifications", the rule of man is greater than the rule of law, which is inconsistent with the Administrative Law and the Property Law. Therefore, the legal profession believes that Du Shanxue is too eager for quick success and instant benefit.

An uncertain ending

　　　　　　　　Ten months later, Du Shanxue, who "swept" a city, became a member of the Standing Committee of Shanxi Provincial Committee in the midst of controversy, and three months later, Du Shanxue became the Secretary General of Shanxi Provincial Committee.

　　　　　　　　Du Shanxue, who walked through the "article road" and played the "image card", finally ushered in the peak of his career.

　　　　　　　　During this period, a person who once worked with Du Shanxue said that Du Shanxue, a member of the Standing Committee of the Provincial Party Committee and Secretary-General, was not as good-tempered as he used to be in Changzhi and Lvliang, and often openly criticized his subordinates, leaving many jobs in a passive situation. "He was restless every day and believed in Zhouyi."

　　　　　　　　The Paper learned that Du Shanxue was interested in Zhouyi as early as during his administration of Changzhi. According to an insider, Du Shanxue pays special attention to "how to walk" besides paying attention to the placement of tables and chairs and the orientation of flowers and plants.

　　　　　　　　The insider said that Du Shanxue believed in a "master" from Henan, and he would ask the master to help him figure out the driving route. Sometimes he felt unlucky on the conventional walking route, so he would take a divination or ask the "master" which way to take.

　　　　　　　　A Changzhi official who had followed Du Shanxue to the countryside for investigation revealed to The Paper that Du Shanxue sometimes changed its route and it was very puzzling.

　　　　　　　　At 6 o’clock in the morning of November 14th, 2005, on the Fen (Yang)-Tun (Liu) Highway in Guodao Town, Qinyuan County, Changzhi City, many teachers and students of a class in Qinyuan No.2 Middle School were crushed to death by a large truck that came at a gallop during morning exercise.

　　　　　　　　At that time, Du Shanxue, the mayor of Changzhi, went to inspect the situation. "They started from Changzhi at 8: 00 a.m. and drove to the scene of the accident for one hour at most, but the motorcade led by Du Shanxue made a detour and went to a nearby village for investigation, and arrived at the scene of the accident near 11: 00 noon."

　　　　　　　　The Changzhi official recalled, "At that time, everyone thought that it was estimated that the mayor was afraid that the scene was too miserable to watch."

　　　　　　　　"Du Shanxue has always been cautious. Over the years, he has indeed formed his own politics." Another person close to the Shanxi provincial government said that with the extension of his official term, Du Shanxue could no longer find a sense of security by "analyzing policies" in his early years, and he had to rely on the culture and experience he believed in.

　　　　　　　　The culture that Du Shanxue believes in is Zhouyi, and the accumulated experience over the years is "making achievements and showing more".

　　　　　　　　Du Shanxue, who returned to work as a member of the Standing Committee of Shanxi Provincial Party Committee, still kept writing. In less than two years, he wrote six articles, covering issues such as "maintaining the purity of the party" and "doing a good job in letters and visits".

　　　　　　　　In February 2014, under the background of "practical education of the Party’s mass line", Du Shanxue published the article "Make good use of the bottom line thinking" to discuss how to serve the people pragmatically and honestly.

　　　　　　　　Thirty-one years ago in the spring, Du Shanxue was transferred to the general office of the provincial government three months after he published the article "Discussion on Budget Funds Outside Management".

　　　　　　　　Thirty-one years later, it was still spring. As a member of the Standing Committee of Shanxi Provincial Party Committee and deputy governor, three months after he published this article "Make Good Use of Bottom Line Thinking", the Central Commission for Discipline Inspection announced the news of his fall.

　　　　　　　　This time, he has been working hard in the officialdom for more than 30 years, and his sense of smell is still sensitive, but his accuracy is reduced.

　　　　　　　　The above-mentioned people close to the Shanxi provincial government said that at one time, when Du Shanxue met people outside the officialdom, he strictly demanded one-on-one, and some people noticed in public reports that his broom-shaped eyebrows began to turn white.

　　　　　　　　After Du Shanxue was taken away, some retired veteran cadres who were familiar with him said, "This smart man, after 30 years, is not bad in the front and middle, but he has no pulse of’ anti-corruption’."

　　　　　　　　

Today, some netizens privately wrote to me in Weibo, and I found two not-so-clear configuration drawings, but these are definitely hard goods, so it is necessary to share them with you immediately. I remember that in the ice and snow test drive of Tang 100, several workers in the black cabin next to it guarded two dark Tang’s, which looked very similar to Tang 100, but felt a little different. I didn’t care at first, but I chatted with my friends from the factory. It turned out that they were testing the 2017 Tang 80!

After many consultations, the manufacturer’s friends did not give the listing time of the 2017 Tang 80, but said euphemistically: "We are also in intensive testing." In any case, this certain model is about to come to our eyes. Let’s take a quick look at the highlights of the exposed configuration tables of the suspected 2017 Tang 80. (Image courtesy of netizens)

　

"Suspected" 2017 Tang 80 Publicity Page ""

As can be seen from the front page of this publicity page, "Suspected 2017 Tang 80" adopts a front face design similar to that of Tang 100. From the blurred picture, it is still unclear whether it is equipped with hood "radiator decoration", but it is obvious that "Suspected 2017 Tang 80" has been replaced with 20 inches of Tang 100. And we can see that in addition to providing the function of VTOL mobile power station, we also upgrade the car CARPAD system, which are completely in line with Tang 100.

"Suspected" Configuration Table of 2017 Tang 80 ""

According to the configuration table of "Suspected 2017 Tang 80", first of all, what is missing compared with Tang 100: 1. There is no memory seat and front heating; 2. There is no ACC adaptive cruise option; 3, cloud services need to be optional (cash and Tang 100 are standard); 4. There is no electric tailgate; 5. There is no driving recorder. At the same time, the car is not equipped with a 220V socket, which is suspected to be adopted, using a wet dual clutch.

There are two configurations shown on the configuration table: 1. Luxury; 2. TAG Heuer, the configuration difference between the two models is mainly in the scientific configuration, such as: 360-degree panoramic image system, 12.1-inch LCD (this should really be standard in the whole system, and only equipped with dual LCD combination in the low-end configuration), VTOL 220V power output, remote control driving, high-fidelity 9,3.3 kW wall-mounted charging box, and advanced exclusive foot pad.

"Suspected" Price List of 2017 Tang 80 ""

Finally, let’s take a look at the suspected quotation sheet. The suspected price of TAG Heuer is 266,000, which is 13,800 lower than the current "model" of 279,800, and the price difference is 33,900 compared with Tang 100′ s 299,900. According to the electric future plan, Tang 100 subsidizes 36,000 yuan, and it is suspected that the price of the 2017 Tang 80 TAG Heuer will be 230,000 yuan! And the "luxury type" suspected of low matching is expected to be within 230,000!

New Travel Wu Ying Comments:

The exposed form has not been officially confirmed, but from the information level, the price of the suspected 2017 Tang 80 is really attractive. Cross-level comparison of the Song DM model (after subsidy) is 209,900. Will the low-grade version of the suspected 2017 Tang 80 luxury model be more attractive? The answer is no. From the above comparison, we can see that the configuration of the low-profile version is quite basic. On the one hand, there is no 360-degree panoramic image, on the other hand, there is no 3.3kW wall-mounted charging box and no standard cloud service system, which is enough to open the configuration difference between the low-profile version of Tang 80 and Song DM.

However, from the consumer’s point of view, the low allocation of Model B and Tang 80 (or less than 230,000) will not form a direct competitive relationship. On the one hand, there are obvious differences in configuration, on the other hand, the positioning people of the two models are different. If the Tang 80 low-end version does not accept reservations within a short time after listing, then the Song DM model is really the only choice to stabilize the 200,000 level. Comparing with the competitors around 230,000, Tang 80 has a certain advantage at this level.

　　"I went to the business hall on Saturday and found that nine out of ten were asking: Where did the traffic go?" Liu Qicheng, a well-known communication expert, lamented in a circle of friends. This is just a microcosm. According to the data of the Ministry of Industry and Information Technology, in April this year, the average mobile Internet access traffic reached 3.41GB, a year-on-year increase of 154%. Traffic consumption has long been commonplace and has become the focus of everyone’s mobile phone package. But at the same time, there are also various questions about mobile phone traffic from consumers: Why do you buy more traffic, but my traffic is getting less and less? Why do you send me so much local traffic when I don’t need it at all? There are so many set meals, why isn’t there my dish?

　　1 Why do I buy more and more traffic, and my traffic is getting insufficient?

　　"The original G was enough for one month, but now it is not enough for 15 days." Many people around are complaining that the mobile phone traffic is not enough, and even many people begin to question the "abnormal consumption" of mobile phone traffic. Some netizens complained on Weibo that they got up in the afternoon and ran away with 19.46GB of traffic. And this abnormal situation is not uncommon. "Stealing traffic" has become a hot word on the Internet. So who stole your traffic?

　　Pei Zhiyong, the chief anti-fraud expert of 360, told the Beijing Morning Post that mobile phone traffic is indeed "running fast" now. The first reason is the change in the usage habits of mobile phone users. In the past, we mainly used text to surf the Internet on mobile phones, and the pictures were often compressed very little. Now, pictures, texts and videos are very popular, and often one picture is four or five megabytes, not to mention all kinds of small videos, which will definitely consume more traffic objectively. In particular, mobile phones are heavily used, and when they stay on social software for a long time, videos that are inadvertently clicked will be quietly downloaded to the mobile phone. Secondly, many softwares run silently in the background even if they are not opened, and even update quietly without your knowledge, which also eats up a lot of traffic. For example, he said that the child had just played Plants vs Zombies, and every time an advertisement popped up, he clicked, and as a result, he unconsciously downloaded a lot of software. There is also an abnormal situation in which illegal software steals traffic.

　　Fiberhome Lab of 360 Internet Security Center has previously discovered a brush cheating Trojan named StealthBot, which adopts a self-hiding method and a mature simulation click process. Like a batch of invisible robots produced by an automatic factory assembly line, it disguises itself as a system service notification, consumes users’ data traffic through startup modes such as automatic operation and external wake-up, and can automatically update and load the latest version of malicious plug-ins in response to instructions issued by the server. Some user groups with weak security awareness and mobile phone brands with poor security have become the areas with the highest occurrence rate of StealthBot. This only exposes the tip of the iceberg where black traffic is rampant.

　　In fact, the era of "not turning off 4G traffic, waking up and moving the house" has long passed. Others question that operators "steal traffic", but this statement is obviously unfounded. Fu Liang, a telecom analyst, believes that it may not be worth the loss for operators to modify the user traffic data. Assuming that operators want to "black" the user traffic, the cost required to transform the system is more than the income brought by stealing traffic.

　　It has been reported that in order to verify the accuracy of traffic measurement by operators, the test results of communication traffic detection conducted by Zhejiang Quality Supervision Bureau and Zhejiang Institute of Metrology showed that SIM cards of three major operators were randomly inserted into three multi-standard wireless communication internet traffic monitors, and the same file was downloaded. The number of repeated tests was 10 times, and the deviation values of traffic detection data were all 0.1% to 0.15%. From the comparison of the test results, there is almost no difference from the traffic statistics provided by operators, so the statement that operators adjust their calculation methods to "steal traffic" is not valid.

　　Why is there so much local traffic, but we can only watch the national traffic run out first?

　　As a patient with severe dependence on mobile phones, Xiao Guo often travels abroad. A package she ordered has 1GB of national traffic, and the operator will also give away 3GB of local traffic. But she found that the national traffic was the first to be consumed, while the local traffic as high as 3GB could not be used. "Why can’t you take the lead in using local traffic when you are in Beijing?" Some users also ridiculed that they received a large amount of traffic from operators at the end of the month, but there was no time to use it.

　　In fact, there are many people like Xiao Guo who "the national traffic is not enough and the local traffic is bursting". However, because the operator sets the priority of national traffic use, the priority of off-package gift traffic is lower than that of in-package traffic. That is to say, use the traffic in the package first, and then the traffic in the package is used up, and the donated traffic can come in handy. However, this embarrassment will soon be a thing of the past, because from July 1 ST, the roaming charges will be completely cancelled, and no distinction will be made between the province, the province/local and the whole country.

　　The Beijing Morning Post reporter noticed that operators often give users a gift of traffic and often launch some promotional activities to grab traffic. However, some insiders pointed out that in fact, for the current traffic giving method, the given traffic often returns to the original road, and the user perception is not strong. Since it’s a gift, why not just be generous? Xiang Ligang, a telecom observer, pointed out that giving away traffic is more of an operator’s market strategy to attract users. However, I believe that after the cancellation of traffic roaming charges, operators may not be so "heroic".

　　3 Say good unlimited package, why speed limit?

　　Operators have been clamoring for "unlimited packages" recently, but it has attracted many consumers’ doubts: after exceeding 20G, they will be slowed down and returned to the 3G era, or even the 2G era, and they will be directly stopped after using more than 100G G. Netizens have complained that the Huimin package has hidden routines and operators lack sincerity.

　　However, in the industry’s view, it is understandable for operators to limit the speed of unlimited traffic packages, which takes care of the choice of most 4G users to use the network fairly.

　　Ceng Jianqiu, a professor at Beijing University of Posts and Telecommunications, pointed out that under the current network conditions, it is difficult for operators to achieve real traffic without capping. Due to the limited bandwidth of the mobile network, it is likely to cause network congestion if multiple users continue to occupy it at high speed at the same time. Previously, AT&T, an American telecom giant, had launched a package with unlimited traffic and speed, but the result was stopped because the network could not bear it.

　　Speed limit is a popular international practice at present, with stepped design — — First, meet the maximum network speed promised by the vast majority of users. After reaching the speed limit, the network speed will drop.

　　Now, if the operator really does not limit the speed, what will happen? As you can imagine, many people turn it into a WiFi hotspot for many people to use together, and then the network will be overwhelmed and the internet speed will become "turtle speed". This obviously deviates from the original intention of operators and consumers.

　　4 why can’t the inexhaustible phone bill be converted into traffic?

　　Consumer Mr. Li calculated an account for the Beijing Morning Post reporter. He is currently ordering a package of 158 yuan from an operator, with 6G of national traffic per month and 700 minutes of talk time. In actual use, the internet traffic is much used, and the traffic is often not enough every month, but most of the call duration is left. "Can the inexhaustible phone bill be automatically converted into traffic?"

　　In fact, this conversion model has long been tried by operators. In 2016, China Telecom took the lead in raising the banner of "full flow billing".

　　In September, 2016, China Telecom Shandong Branch launched a new mode of full traffic charging, which converted voice and SMS into traffic for charging, and voice and traffic can be converted freely. Among them, 1M is equal to 1 minute, and how much M traffic will be deducted for how many minutes you make a phone call, and there will be no balance of call duration in the package. At the same time, the "domestic traffic" in the package can be converted into "domestic calls". In addition, some other local companies of China Telecom have also tried the water. However, Beijing has not yet been realized.

　　In addition, China Mobile also plans to pilot the unit price charging model of flow ladder in some cities.

　　However, this model is not popular at present. In Xiang Ligang’s view, full flow billing is technically not difficult, but operators have invested a lot in changing the billing system. Most importantly, with the coming of 5G, the operator’s billing system may be reshaped, so the operator does not have much enthusiasm at present.

　　5 why can’t I combine freely, and my package is my decision?

　　As a senior mobile phone user, retired worker Lao Li’s confusion is that there are so many packages of operators that people are dazzled, but none of them are my dishes. The ideal model is that I provide the monthly consumption demand, and then the operator tailors the most suitable package.

　　Obviously, the tariff that Lao Li wants is a "private subscription" model. In fact, operators have similar schemes. For example, as early as 2013, China Telecom launched a nationwide unified customer-selected tariff scheme — — Building block package. In order to help customers match "building blocks", China Telecom has provided many humanized auxiliary tools, such as flow calculator and flow application examples. The building block package consists of four "building blocks": voice, traffic, SMS and 3G applications. Customers can mix and match freely according to their own consumption needs, and change the package as needed at any time.

　　China Mobile and China Unicom also have similar "building block packages", which are designed to freely match voice calls and Internet traffic. However, the space for users to choose is still limited. For example, open the client of an operator and find the package calculator, which recommends the appropriate package according to your consumption and use in recent months, but the minimum recommended voice is 18, which obviously cannot meet the needs of Lao Li’s DIY. Therefore, this service has not achieved real success and popularization in the three major operators.

　　Ma Jihua, a senior telecom analyst, pointed out that after years of development, telecom operators are constantly innovating and the package system is huge, which can not only confuse customers, but even business people themselves don’t quite understand it. In this case, it is easy to cause the external performance of price opacity, giving users the feeling that they are being fooled. Packaging consumption allows users to enjoy more affordable prices than single accumulation, but many people have no demand for some additional parts and often feel forced to spend. Even if you use it for free, you still feel uncomfortable.

　　6 Why do new and old users treat each other differently?

　　With the deepening of speed-up and fee reduction, new mobile phone tariff schemes emerge one after another. Every season, operators will try their best to introduce new selling points to attract users. For example, campus promotion large-flow packages, such as mobile broadband bundled fusion packages. But many new packages that look beautiful are only for new users, and old users are blocked out.

　　For example, the unlimited card of Beijing Mobile 68 yuan is only for new users. The most favorable unlimited traffic package that old users can choose is 98 yuan/month, which contains 150 minutes of voice and 20G of domestic traffic. After the traffic is exhausted, the speed limit of surfing the Internet is up to 1Mbps. After the accumulated traffic in the month exceeds 100G, you can continue surfing the Internet, but the speed limit is 128Kbps. Beijing Telecom’s 65 yuan Convergence Package is only for new users, and it needs to be paid for two years.

　　It has been a fact for many years that there is a certain gap between operators’ care for old users. Why should new and old users be treated differently? Some operators have no choice but to complain that the market is getting saturated and the growth rate of users is slowing down, and the purpose of many promotions is to grab passengers, so the promotion is strong. However, old users enjoyed the preferential scheme at that time when they accessed the network.

　　In November last year, because of the problem of old users switching to Internet packages, the Ministry of Industry and Information Technology called on telecom operators to provide convenience for old users to change packages, and not to introduce plans to restrict old users from choosing tariffs, and asked enterprises to sort out and investigate existing tariff plans. If there is any behavior that restricts users’ tariff options, it will be rectified immediately.

　　Fu Liang, a telecom analyst, believes that the ideal way is to operate a user from the moment the user enters the door, so that users can feel cheaper and cheaper tariffs and better and better services, instead of attracting users with high preferential policies and then letting them go. In his view, it is still common that old packages are not upgraded or old users still need to take the initiative to apply for outdated tariffs.

　　However, in the context of market saturation, "please" old users is the cornerstone of building stability. In particular, port number transfer will be fully implemented in 2020, and it is time for operators to be nice to old users.

　　Tips for saving mobile phone traffic

　　Although the traffic charges are getting cheaper and cheaper, many small partners exclaim that the traffic charges are increasing. Especially at the end of each month, the traffic is shy. In fact, there are many tips to save traffic and prevent it from sneaking away.

　　1. Download applications through formal channels.

　　Applications downloaded from the third-party software market are risky, and some illegal software will steal traffic. Therefore, friends should try their best to download applications in formal channels, such as the mobile phone manufacturer’s own app store, official website, etc., so as to avoid accidentally installing traffic-brushing software.

　　2. Turn off the automatic synchronization function

　　Turning on the automatic synchronization function of the mobile phone will consume a lot of traffic in the background without your attention, so it is best to turn off the automatic synchronization function or choose to synchronize only under the WiFi network.

　　3. Close the background running program.

　　Many times when we close an application, we return to the desktop directly. If there are too many internet-connected apps in the background, when they are on standby, they may constantly refresh and access data. Therefore, it is necessary to develop the habit of closing and cleaning up the background operation of apps in time, leaving only the software that needs to be online all the time. This can also improve the running speed of the mobile phone to a certain extent. Nowadays, many mobile phones provide a shortcut to close the application with one button.

　　4. Turn off the mobile data of the mobile phone

　　When not surfing the Internet or using WiFi, remember to turn off the mobile phone to move data, which can fundamentally prevent the background program from consuming traffic. Especially in the environment with WiFi, although the system will give priority to WiFi, it will automatically switch to mobile data under special circumstances or when the signal is bad.

　　5. Restrict the Internet connection of large customers who eat traffic.

　　Apple Edition: Open Settings → Cellular mobile network can query the situation of traffic consumption, thus limiting the networking of designated applications.

　　Android version: Open the security center in the mobile phone settings, and you can query the traffic consumption of each application, thus restricting the designated applications from connecting to the Internet.

　　In fact, the most popular apps are several commonly used apps, which can be found in the data traffic usage of mobile phones. Generally, WeChat, QQ, browsers and game software are all big traffic users. Some measures can be taken, such as: WeChat friends circle small video opens the automatic playback setting in WiFi-only environment; Try to use compressed photos when drying photos in your circle of friends; Try to communicate in pure text, and send less emoticons, voices and short videos; Don’t click on links, short videos, photos, etc.

　　6, set the daily flow limit

　　It is suggested that the monthly traffic usage limit or early warning should be set in the [Security Center] in the mobile phone settings, so as to find out the abnormal traffic consumption in time.

　　7. Pay attention to the application scope of directional flow.

　　At present, operators and major Internet companies have launched a number of targeted packages, such as Tencent King Card swiping WeChat, watching Tencent videos and playing the glory of the king, which are free of charge. However, if you occasionally brush a Weibo and send a Tik Tok, you will have to pay an extra traffic fee. When ordering these packages, pay attention to their limited scope.

　　8. Multi-operator wool

　　At present, operators often launch some activities such as traffic giving, lottery, special offer, etc. on many holidays, and pay attention to official platforms such as operators’ clients, public accounts and Weibo, which are often hit by free traffic. For example, Beijing Mobile client has a regular activity of signing in to send traffic, and can get a total of 160M traffic coupons for free every month. And Beijing telecom can get a total of 300M traffic when signing in.
