21st century business herald reporter sha li reports from Beijing. On the afternoon of January 8, the State Council held a press conference to introduce the situation and work arrangement of Spring Festival travel rush in 2025.

The reporter learned from the press conference that the Spring Festival travel rush in 2025 will last for 40 days from January 14th to February 22nd. Transportation and other departments predict that during the period of Spring Festival travel rush, the cross-regional mobility of the whole society will reach 9 billion passengers, and the passenger traffic of railways and civil aviation is expected to exceed 510 million passengers and 90 million passengers respectively, both reaching record highs. Self-driving travel will remain the dominant position, with an estimated 7.2 billion person-times, accounting for about 80% of the cross-regional flow of people in the whole society, and the peak of expressway traffic volume may reach a record high in a single day.

Li Chunlin, deputy director of the National Development and Reform Commission, said at the press conference that this year’s Spring Festival is earlier than in previous years, and there will be a superposition of students, workers, visiting relatives and tourists around the Spring Festival, with a high concentration. Urban agglomerations such as Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong, Hong Kong and Macao and Chengdu-Chongqing are still the main concentration areas of passenger flow. Considering that the transportation in Spring Festival travel rush will be upgraded to full capacity in a short time, there is great pressure on ensuring smooth flow, safety, preventing bad weather and coordinating passenger and cargo transportation.

In this regard, Li Chunlin said that the National Development and Reform Commission, in conjunction with relevant departments, studied and planned as early as possible and comprehensively adopted a number of measures to meet the travel needs of residents, including increasing transportation capacity, guiding travel, ensuring smooth flow and optimizing services.

The railway sent 12.75 million passengers every day.

The starting time of Spring Festival travel rush in 2025 is 12 days earlier than that of Spring Festival travel rush in 2024, and the train tickets for Spring Festival travel rush have been put on sale. On the morning of January 8th, some netizens reported that the 12306 mobile APP could not log in normally, and "12306 crashed" rushed to Weibo for hot search. After emergency disposal by the technical team, the APP has resumed normal operation.

The reporter learned from the press conference that the number of passengers sent by railways in Spring Festival travel rush this year is expected to exceed 510 million, with an average of 12.75 million passengers per day, an increase of 5.5% compared with that in Spring Festival travel rush in 2024.

Zhu Wenzhong, head of China State Railway Group Co.,Ltd. Passenger Transport Department, said at the press conference that the overall passenger flow of Spring Festival travel rush Railway will increase steadily in 2025; The passenger flow will still show obvious one-way characteristics, but the reverse passenger flow will further increase; In some periods and directions of peak passenger flow in Spring Festival travel rush, such as from Guangzhou-Shenzhen area to Changsha, Wuhan and Chengdu-Chongqing before the Spring Festival, there is still a contradiction between traffic volume and transportation capacity.

In this regard, Zhu Wenzhong pointed out that China State Railway Group Co.,Ltd. has made great efforts to increase the capacity in the direction of concentrated passenger flow in Spring Festival travel rush, make overall arrangements for trains in the direction of non-concentrated passenger flow, maintain the scale of ordinary passenger trains, and run public welfare "slow trains" and "rural revitalization" passenger trains. More than 14,000 passenger trains are arranged every day, which can add about 500,000 seats every day, and the passenger capacity increases by about 4% year-on-year.

Zhu Wenzhong further mentioned that before the Spring Festival, in areas with concentrated passenger flow such as Beijing, Shanghai-Nanjing-Hangzhou and Guangzhou-Shenzhen, China State Railway Group Co.,Ltd. arranged to operate 1,724 pairs of long-distance passenger trains every day, an increase of 64 pairs year-on-year; At the peak of passenger flow, 329 pairs of long-distance high-speed trains were arranged at night, an increase of 38 pairs over the same period of last year. After the Spring Festival, 871 pairs of long-distance passenger trains were arranged daily in Chengdu-Chongqing, Wuhan, Nanchang, Hunan and other areas with concentrated passenger flow, an increase of 46 pairs year-on-year; At the peak of passenger flow, 170 pairs of long-distance high-speed trains were arranged at night, an increase of 31 pairs.

Zhu Wenzhong pointed out that according to the travel needs of passengers, China State Railway Group Co.,Ltd. has continuously improved its service measures, such as optimizing the functions of the 12306 system, scientifically formulating ticketing strategies, optimizing the pre-filling function of ticketing information, increasing the ticketing services for students and migrant workers, and ensuring the travel of key groups.

Self-driving travel accounts for about 80%

This year, the cross-regional mobility of people in Spring Festival travel rush is expected to hit a new record high, of which 80% will pass through expressways and ordinary national and provincial highways, making self-driving travel more prominent, which may form a travel peak.

In this regard, Wang Qiang, director of the Traffic Management Bureau of the Ministry of Public Security, said at the press conference that in order to ensure residents’ travel during Spring Festival travel rush, the Ministry of Public Security has started relevant work and made a series of arrangements, especially for passenger and cargo transportation, self-driving travel and other traffic safety issues. Specifically includes the following aspects.

The first is to comprehensively investigate and manage potential safety hazards. The Ministry of Public Security has deployed and launched a nationwide public security system to prevent production safety risks, and jointly with relevant departments, comprehensively investigated the traffic safety hazards of people, vehicles, roads and enterprises, prohibited unqualified vehicles and unqualified drivers from participating in Spring Festival travel rush, and promoted the hidden dangers management of bridges and tunnels, sharp bends and steep slopes, water and cliffs, highway entrances and exits and accident-prone points. At the same time, the Ministry of Public Security has also deployed targeted traffic management measures for the peak hours of road traffic, such as from off-year to New Year’s Eve in 2025, visiting relatives and visiting the garden during the Spring Festival holiday, and returning home after the Spring Festival holiday.

Second, the whole police mobilized to escort Spring Festival travel rush safely. During the period of Spring Festival travel rush, local public security traffic control departments will set up traffic police law enforcement stations at busy traffic points, and put police force and emergency disposal equipment on the road to the maximum extent. The national traffic police auxiliary police will focus on key time periods, key road sections and key vehicles, strictly investigate traffic violations that are easy to cause trouble and disrupt traffic order, and make every effort to ensure safe and smooth road traffic.

The third is to provide maximum security for safe travel services. During the period of Spring Festival travel rush, especially during the peak hours of concentrated travel, the public security traffic police will rely on various media, as well as new means and applications such as dual micro platforms and map navigation, and timely release information such as road information, traffic guidance and safety tips to guide residents to cooperate with the road guidance.

During the period of Spring Festival travel rush, many residents also chose new energy vehicles to travel by car. In this regard, Gao Bo, head of the Transportation Service Department of the Ministry of Transport, said that by the end of November 2024, the national expressway service areas (including parking areas) had built a total of 33,100 charging piles and 49,300 charging parking spaces, and the proportion of expressway service areas with charging facilities had increased from 85% at the end of 2023 to 97%. Except for a few high-altitude service areas, it has basically achieved full coverage.

　　1948年11月6日至1949年1月10日，我华东野战军和中原野战军在地方部队的配合和广大人民群众的支援下，历时66天，在以徐州为中心，东起海州、西至商丘、北自临城、南达淮河的广大区域内，发起了伟大的淮海战役(国民党方面称为“徐蚌会战”)。战役首歼黄伯韬兵团，继歼黄维兵团，再歼杜聿明集团，解放军以伤亡13.4万余人的代价，歼灭国民党军5个兵团、22个军、56个师，共计55.5万余人，创造了战争史上以少胜多的奇迹。淮海战役是解放战争战略决战中历时最长、规模最大、歼敌数量最多的一次战役。淮海战役的伟大胜利，解放了长江以北华东和中原的大部分地区，使国民党统治中心南京和上海直接暴露在人民军队的铁拳面前，加速了解放全中国的历史进程。广大人民群众不怕牺牲，义无反顾地投入战争之中，为淮海战役的胜利做出了永不磨灭的伟大贡献。

　　大决战前夜

　　1948年初秋时节，天高云淡，金风拂面。河北省平山县西柏坡这个太行山麓、滹沱河畔的小山村更是赏心悦目。此时，中共中央正在这里召开政治局扩大会议(史称九月会议)。中国已经进入了大决战的前夜，以毛泽东为核心的中共领导集体，正酝酿着重大决策。

　　The People’s Liberation War has entered the third year, and the military, political and economic situation in China has undergone major changes that are more beneficial to the people and not conducive to the Kuomintang ruling clique. Although the total strength of the Kuomintang troops has remained at about 3.65 million by constantly "recruiting able men", most of them were rebuilt after being wiped out or severely hit by our army, with low morale and weak combat effectiveness. There are 249 brigades (divisions) with 1.7 million people in the Kuomintang regular army distributed in the front line, which are confined by the People’s Liberation Army in five battlefields: Northeast China, North China, Northwest China, Central Plains and East China. Most of them can only defend strategic points and main traffic lines, and their strategic mobile forces are already stretched. The forces in the enemy’s rear are weak in fighting capacity, and they are restrained by our guerrillas and cannot be maneuvered. With the military defeat, the political crisis of the Kuomintang government became more and more serious, and the economy of the Kuomintang-controlled areas was rapidly collapsing. Contrary to the Kuomintang army, the People’s Liberation Army has grown rapidly in the battle, with a total strength of 2.8 million (including 1.49 million field troops). The area of the liberated areas has expanded to 2.35 million square kilometers and the population has reached 168 million. Most of the liberated areas have carried out land reform, and the revolutionary and production enthusiasm of the peasants who have turned over has never been higher, and production has resumed development. Because of the stability in the rear of the liberated areas, our PLA troops can be concentrated on front-line operations, and the front-line mobile forces are already superior to the Kuomintang troops.

　　On September 24, the spring city of Jinan, the summer heat gradually disappeared, and autumn began to flourish. As the acting commander and political commissar of Hua Ye, Su Yu has spent many sleepless nights. On this day, the guns of the general attack on Jinan have sounded, Jinan City is about to return to the people’s arms, the two liberated areas in North China and East China are completely connected, and Chiang Kai-shek’s "key defense" system with big cities as the mainstay has begun to collapse. At this moment, Su Yu’s eyes are tightly fixed on the Huaihai area with Xuzhou as the center below Jinan on the map, as if hordes were rushing in his chest, and gradually, a grand blueprint for the campaign was formed in his mind.

　　On the same day, Su Yu called the Central Military Commission and reported it to the East China Bureau and the Central Plains Bureau, suggesting that Hua Ye’s main force should leave northern Jiangsu from southern Shandong and hold the Huaihai Campaign to attack enemy groups in Xuzhou, wipe out the enemy or force the enemy to retreat, so as to create conditions for crossing the river in the future. The next day, the Central Military Commission immediately called back: "It is very necessary to hold the Huaihai Campaign". Liu Bocheng, commander of the Central Plains Field Army, and Chen Yi, deputy commander (and commander of Hua Ye and political commissar) also quickly replied, agreed to push their victory to launch the Huaihai Campaign, and prepared to lead the various ministries of Nakano to take the policy of separating operations and attack the western Henan and Longhai railway lines respectively to cooperate with Hua Ye.

Why did the recent Ukrainian attack on the Russian Black Sea Fleet succeed frequently? The increasing battle damage of the Russian Black Sea Fleet will have an impact on the situation in Russia and Ukraine?

Intended to cut off Russian supplies

Data map: Russian Black Sea Fleet (Source: CCTV pays attention today)

The Ukrainian side said on March 24th that the Ukrainian Defence Forces had hit the landing ships Yamal and Azov of the Russian Black Sea Fleet, a communication center and many infrastructures.

Analysis of Ukraine’s recent combat operations, military observer Zhou Weizheng believes that this is to further weaken the Russian military’s logistics supply capacity in relevant directions.

Zhou Weizheng: The Ukrainian army’s recent operational focus is to crack down on Russia’s logistics supply links, using air-to-ground cruise missiles, drones and unmanned boats to crack down on Russian refineries, thermal power plants, material and oil warehouses and other infrastructure. Landing ships, as an important supply vehicle in the south of Russia, have also become the key targets of the Ukrainian army.

If the attack did injure two Russian landing ships, as the Ukrainian army said, it would add insult to injury to the Russian Black Sea Fleet, which would further weaken the Russian military’s logistics supply capacity in the direction of Zaporoze and Hellson. If the Crimean Bridge is hit again in the next step, then Russia’s logistics supply will become a major issue affecting the trend of the situation.

It has little impact on the overall situation of Russia and Ukraine.

Zhou Weizheng said that although the Russian Black Sea Fleet has been damaged in recent wars, it will not have a major impact on the overall war situation in Russia and Ukraine.

Zhou Weizheng: Judging from the current overall situation, Russia’s attacks are mainly concentrated in the direction of Donetsk and Zaporoge, and the amphibious landing operation in the sea direction has basically been abandoned.

Although the losses caused by Ukraine to the Russian Black Sea Fleet are increasing, it is difficult to have a fundamental impact on the situation in Russia and Ukraine.

How to defend against suicide unmanned boats?

Data map: Wujun unmanned boat (Source: CCTV pays attention today)

After the outbreak of the conflict between Russia and Ukraine, unmanned boats created a brand-new style of asymmetric warfare in modern naval warfare, which also made how to defend against suicide unmanned boat attacks a topic of great concern.

In this regard, Zhou Weizheng analyzed.

Zhou Weizheng: One of the important reasons why the unmanned boats of the Ukrainian army are outstanding in actual combat is that the Russian army lacks sufficient and powerful early warning aircraft and drones, and its full-time and all-round battlefield situation awareness ability is relatively weak. The attacked ships have single defense means and limited capabilities.

In the future, to deal with unmanned boats, it is necessary to improve the joint reconnaissance and search ability of land, sea and air, grasp the specific information of the unmanned boat’s release base or the mother ship it carries, and then use long-range precision firepower to attack and destroy it from the source or during the voyage. If there is a "fish escaping from the net", electronic jamming can be carried out on the unmanned boat, its communication link can be cut off, and the sensor on the boat can be blinded. At the same time, laser and high-precision near-anti-gun system can be used to intercept it.

　　Chengdu Wan Chuan Company, the construction team of Tibet Telecom, is setting up a new communication pole in Kenken Village, Medog County, Linzhi City, and opening an optical fiber network for Kenken Village. On rainy days, the road is slippery, and Kenken Village is located on a high mountain cliff, so the construction environment is very dangerous.

　　Construction personnel of China Mobile Tibet Company braved the gale of magnitude 7 or 8 to debug equipment on the communication pole of Pula Village, Luoma Town, Naqu City.

　　After Tibet Telecom opened fiber-optic broadband to Laba Tsering, a villager in Kenken Village, Medog County, Linzhi City, the whole family took their mobile phones to connect to the Internet with WiFi signals. Their family also sells Medog stone pot online.

　　Economic Daily China Economic Net reporter Huang Xin

　　Core tips

　　In December 2015, the Ministry of Finance and the Ministry of Industry and Information Technology launched the pilot project of universal telecommunications service, which proposed that by 2020, 98% of administrative villages would be connected with optical fiber and 98% with 4G communication signals. What is the progress of the pilot construction of telecom universal service?

　　The reporter’s investigation in Tibet, which has the highest altitude and the worst natural conditions, found that the construction conditions of telecom infrastructure here are extremely difficult, and the network construction period is long. At the same time, due to the small revenue and huge maintenance cost, it faces greater financial pressure. Fortunately, the network has effectively narrowed the digital divide, provided the basic conditions for "accurate poverty alleviation in internet plus" and opened up the "last mile" of information poverty alleviation.

　　The annual "May 17th World Telecommunication and Information Society Day" includes "sharing" no matter how the theme changes. Adhering to the purpose of sharing, since December 2015, the Ministry of Finance and the Ministry of Industry and Information Technology have launched a pilot project of universal telecommunications service to promote the construction and development of broadband networks in administrative villages without broadband access. The goal is to achieve 98% administrative villages with optical fiber and 98% administrative villages with 4G communication signals by 2020.

　　"At present, three batches of pilot central financial subsidies and basic telecommunications enterprises have invested more than 40 billion yuan to support more than 130,000 administrative villages to connect optical fibers." According to Wen Ku, director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, as of the end of March, the completion rate of the first two batches of 101,000 pilot administrative villages has exceeded 99%, and the third batch of 32,000 administrative villages is accelerating construction; The proportion of administrative villages in China has reached 95%, and it is expected that the goal of 98% administrative villages connecting with optical fibers proposed by the national "Thirteenth Five-Year Plan" will be achieved ahead of schedule by the end of this year.

　　At present, what is the progress of the pilot construction process of telecom universal service? What problems have you encountered? The Economic Daily reporter recently followed the relevant personnel of the Ministry of Industry and Information Technology to conduct in-depth research in poor rural areas in Tibet. Tibet can be said to be one of the hardest areas in the national pilot of universal telecommunications service. Tibet is the only provincial-level concentrated contiguous poverty-stricken area in China, with low per capita income, high altitude, frequent rain and snow, and backward transportation and power generation conditions, which makes communication construction difficult and high maintenance cost in the later period. Tibet’s telecom universal service has a demonstration and reference significance in the whole country.

　　The construction conditions are extremely difficult.

　　Tibet has a high altitude, frequent rain and snow, frequent road collapses or blockages, extremely difficult construction conditions and a long network construction period.

　　The road to Medog is known as "Medog Road of Life and Death". The world only knows that Shu Dao is difficult, but it is even more difficult to enter Medog. Because it is located in the Himalayan fault zone and the Medog fault zone, the 140 km distance from Bomi to Medog is full of frequent geological activities, and natural disasters such as earthquakes, landslides and mudslides may occur at any time, and the road surface is muddy and bumpy. The distance from Medog main road to Kenken village in Bangxing township is 35 kilometers, which is even more winding and dangerous.

　　The reporter’s interview in Kenken Village, Bangxing Township, Medog County coincided with a rainy day, with cliffs on one side and abyss on the other. It was really walking on thin ice. Under such natural conditions, Chengdu Wan Chuan Company, the construction team of China Telecom, is setting up a new communication pole in Kenken Village to open an optical fiber network for Kenken Village.

　　"The road here is not easy to walk, and cars can’t get in. Many materials and equipment have to be carried by people. It rains most of the time from April to October every year, and there are many leeches and snakes in the forest, which has a certain impact on the construction progress. In order to ensure the smooth progress of the project, we must work overtime on the premise of ensuring safety. " Li Benjun, a technician of Chengdu Wan Chuan Communication Engineering Co., Ltd., said.

　　The difficulties encountered in connecting optical fibers in remote rural areas of Tibet are far more than these. Gombudoji, deputy director of Tibet Communications Administration, told reporters that Tibet is high in altitude and difficult to construct, and many construction units are reluctant to go to Tibet for construction. At the same time, frequent rain and snow often lead to road collapse or blockage, and the network construction cycle is long.

　　Pula Village, located in Luoma Town, Naqu City, with an average elevation of more than 4,700 meters, is cold and oxygen-deficient, with a vast territory and few people. At the communication construction site in Pula village, the reporter saw another difficult scene different from Medog: because the altitude exceeded 4,700 meters, the communication construction workers had headaches and tinnitus, but they had to climb to the communication pole for equipment debugging. There is still a strong wind of seven or eight here, and the construction workers should tie themselves with ropes to prevent them from falling off the poles.

　　"In Tibet, China Mobile has the largest number and the widest scope of telecom universal service villages, and the construction conditions are extremely difficult." Tenzin Junmei, manager of the Engineering Construction Center of China Mobile Tibet Company, said that in 2017, China Mobile Tibet Company invested a total of 827 million yuan to build 13,000 kilometers of new optical cables, and completed the construction of universal telecom services in 1,786 administrative villages in four cities of Xigaze, Shannan, Qamdo and Naqu, accounting for more than 57% of the administrative villages in the region. Most of these administrative villages are located in extremely remote and extremely cold areas, with an average altitude of more than 4,700 meters, an average annual temperature of MINUS 15 degrees Celsius, and a perennial wind force of more than 6, and individual administrative villages have an altitude of more than 5,300 meters.

　　For example, Tenzin Junmei said that in the construction process, the most difficult thing is the construction of universal telecommunications services in villages in Naqu City. The frozen soil layer of Qiangtang grassland is more than 1 meter deep, and only cow dung can be used to melt the frozen soil and bulldozers can the communication poles be implanted.

　　Under such difficult conditions, according to Kampot Dorje, at present, 3044 of the 3126 pilot administrative villages in the first and second batches of universal service work of Tibet Telecom have been completed, and 82 pilot administrative villages cannot be built due to relocation and road impassability. The third batch of projects involves 2084 administrative villages and is currently in the construction stage. It is expected that the construction and acceptance will be fully completed by the end of 2018. After the completion of the three pilot projects of universal telecommunications service, Xizang Autonomous Region will, together with the whole country, realize that 98% of administrative villages will be connected with optical cables and 100% with broadband.

　　"It is precisely because of this difficulty that the pilot of universal telecommunications service in Tibet is more exemplary." Wen Ku said that in the pilot project of universal telecommunications service, the focus has been on accelerating the process of broadband access for poor villages. At present, three batches of pilot projects have supported 43,000 poverty-stricken villages to access optical fiber, which has achieved the goal of "broadband network covering more than 90% poverty-stricken villages" put forward in China’s "Thirteenth Five-Year Plan for Poverty Alleviation" ahead of schedule.

　　The investment in human and financial resources far exceeds the income.

　　The revenue of telecom service users in Tibet is small, and the maintenance cost is huge. In addition to subsidies, operators need to adopt internal cross-subsidies to maintain it.

　　On May 9, despite the heavy rain, the door of Raba Tsering’s home in Kenken village was surrounded by villagers. At 3: 40 p.m., the telecom staff in the house operated the communication equipment they brought and told Raba Tsering that "the network has been connected".

　　The reporter learned that the monthly price of telecom broadband package in the city with the same specification is 199 yuan, while Raba Tsering only needs to spend 79 yuan. Similarly, in Naqu area, China Mobile has provided an exclusive tariff for the pilot project of universal telecom service, and the maximum monthly consumption of 48 yuan can enjoy 50M fiber-optic broadband and high-definition digital TV. According to statistics, in order to ensure that local herders can use and afford broadband, China Mobile Tibet Company has launched a special tariff for universal telecommunications service according to the actual situation of each city. For poor households and low-income herders, the overall charge is only 50% of the average market price.

　　Although the price is half cheaper, the network speed is not discounted. Taking China Mobile Tibet Company as an example, in 1786 administrative villages in Shigatse, Shannan, Qamdo and Naqu, which are supported by telecom universal service, the average network access rate reaches 50M, which is higher than the 12M standard required by Xizang Autonomous Region government.

　　This is the significance of telecom universal service &mdash; &mdash; Let anyone enjoy telecommunications services at an affordable price anywhere. However, behind these preferential policies, a lot of financial support is needed.

　　In order to promote the universal service of telecommunications, in addition to the partial compensation funds provided by the state, operators also need to adopt internal cross-subsidies to solve the problem that the investment far exceeds the return. According to Feng Wenyong, Party Secretary and Director of Tibet Communications Administration, at present, there are 5,210 administrative villages in Tibet, with a planned total investment of about 3 billion yuan, of which the Ministry of Finance has issued a total subsidy of 853 million yuan, and the winning bidders have raised about 2.147 billion yuan.

　　On the one hand, it is difficult for communication enterprises to rely on the business income of telecom universal service users to support costs. Kampot Dorje said frankly that Tibet is the only provincial-level concentrated contiguous poverty-stricken area in China, and it is also a border minority area. The poverty alleviation channel in agricultural and pastoral areas is relatively single, the per capita income level is low, and the user demand is low, which leads to the difficulty in the development of broadband users and the low revenue efficiency of enterprises after the completion of this project.

　　On the other hand, "it is difficult to build a network and it is more difficult to maintain it. For example, in Kenken Village, we concentrate our efforts and resources to build the network in a month or two. However, under such natural conditions, it is very difficult to maintain the network and we need to continuously invest money. " Nima Dunzhu, deputy general manager of China Telecom Tibet Company, said.

　　On the way to Kenken Village, the reporter met Yan Fengqin, an employee of Medog Station of Linzhi Telecom Transmission Bureau, who was inspecting communication optical cable equipment in the forest. In order to prevent the bite of leeches, snakes, etc., his trouser legs are tied tightly with socks. This is nothing to Yan Fengqin, who is more worried about the occurrence of natural disasters such as mudslides or flash floods that affect life safety.

　　Nima Dunzhu calculated an account for the reporter: Taking Kenken Village as an example, the construction cost of optical cable lines and equipment investment reached nearly 2 million yuan. The maintenance cost of ordinary villages needs 100,000 yuan a year, but Kenken Village is far more than that. There are only 29 households in the village, and even if all broadband services are opened, the annual income is only nearly 30,000 yuan. Because of the unstable power supply, China Telecom has to generate electricity by itself to ensure the smooth network, so it also bears a lot of power generation costs.

　　"There are many places in Medog where there are dense forests and it often rains. It is not feasible for us to generate electricity through solar energy." Gombudoji said that by 2020, there are still 12 counties in Tibet that can’t access the national grid, and there are more than 500 administrative villages in the 3044 pilot administrative villages with universal telecommunications service that have completed the construction task, which can’t meet the equipment operation requirements of the project.

　　Co-construction and sharing to reduce costs

　　Operators realize the open sharing of power towers and communication towers through cooperation with power grids and railways, and at the same time strengthen the synchronous design and construction of communication lines with high-speed rail lines.

　　It is precisely because the investment in telecom universal service far exceeds the return that all countries in the world have set up special fund subsidies, and China is no exception. It is understood that the subsidy scale of China’s universal service fund is based on the input cost of telecom universal service in sub-regions recognized by the Ministry of Industry and Information Technology and the Ministry of Finance, and the eastern, central, western and autonomous provinces (autonomous regions and municipalities) subsidize according to 15%, 20%, 30% and 35% of their base respectively, and carry out according to the idea of "central fund guidance, local coordination support and enterprise-oriented promotion".

　　The reporter also learned in the investigation that the central funds have taken into account the later maintenance costs when subsidizing. At the same time, some local governments will also give different financial support.

　　"We also saw in the process of implementing the universal service of telecommunications that there were not many people applying for broadband services in some administrative villages at first, but after the opening of the network, the number of applications for broadband services increased, and the telecom operators responsible for construction could achieve balance of payments and even profit." Wen Ku said.

　　Nevertheless, in practice, telecom operators still feel that the construction and follow-up maintenance funds of telecom universal service exceed expectations. With the development of communication technology, telecom operators are actively reducing the cost of telecom services through co-construction and sharing. In the survey, the reporter saw that a telecom operator will leave a channel for other telecom operators when building a communication pole. At the same time, with the support of the Ministry of Industry and Information Technology, operators are also strengthening cooperation with power grids and railways to realize the open sharing of power towers and communication towers, and the synchronous design and construction of communication lines and high-speed rail lines.

　　It is under such persistence that broadband networks can quickly enter poor areas, effectively narrowing the digital divide, providing the basic conditions for "accurate poverty alleviation in internet plus" and opening up the "last mile" of information poverty alleviation.

　　Medog Stone Pot is famous far and near. "With the optical fiber network, we can put the stone pot online to sell, and we can also get in touch with people outside and understand the outside world." Raba Tsering, who just opened an optical fiber network at home, said.

　　In the home of Bianbazaxi, a villager in Pula village, he happily introduced the information and communication products at home and sent his newly-made Tibetan clothes to his circle of friends. Sales of Tibetan clothes at home have doubled since broadband was connected at home.

　　Rural tourism and characteristic industries have also been gradually promoted. Take Kenken Village as an example, the local area has vigorously developed characteristic industries to the outside world through the network platform, and expanded the ways for farmers and herdsmen to increase their income and get rich. Hong Weidong, secretary of the Party branch of Kenken Village, said that during the slack season, they would sell local specialties to customers thousands of kilometers away through the Internet. China Mobile’s 100M fiber-optic broadband has been connected to Pula Village, which not only provides convenient and efficient information life for the whole village, but also effectively broadens the sales of yak meat, yogurt and other special agricultural and livestock products in the village.

　　"We encourage basic telecommunications companies to introduce preferential network tariffs for poor areas and poor people, and promote the widespread use of broadband networks in poor areas. Support broadband network access to schools, clinics, village committees, etc., and cooperate with relevant departments to promote information construction in education, medical care, e-commerce, etc. We hope that this will drive the poor to increase their income and become rich and promote the equalization of basic public services in rural areas. " Wen Ku said.

　　Wen Ku revealed that it will continue to accelerate the pace of high-speed broadband access to the village. All 43,000 poverty-stricken villages in the three batches of pilot projects to promote universal telecommunications services will be completed by the end of this year, and the pilot projects of universal telecommunications services will continue to be deepened, with emphasis on supporting the coverage of 4G networks in remote rural areas. The poverty-stricken villages that still do not have access to broadband will be investigated and accounts will be established, giving priority to the scope of support. On the basis of completing the basic goal of broadband access to 90% of poor villages, efforts will be made to increase the coverage rate to over 98%.

What’s your main impression of this car after reading the whole article? This class of cars can often give consideration to both cost performance and practicality, and is often considered by most consumers as the first choice when buying a car.

The three parts of a car refer to the engine, transmission and chassis. These three systems are the core of the car and the most important parts in the car. Today, let’s explain the gearbox of the car.

The gearbox plays an important role in vehicle speed change, torque change and reversing. According to the performance and demand of different models, cars on the market are also equipped with different types of gearboxes. When the owner buys a car, he will also pay special attention to the gearbox, and generally will not choose to buy a car with poor gearbox performance.But do you know which gearboxes are most stable and reliable? What are the top ten gearboxes in the world in 2021? Let’s take a look at it together!

First, ZF gearbox

Allison has the highest level of R&D and production capacity in the field of heavy-duty vehicle gearboxes.Widely used in passenger cars, garbage trucks, emergency rescue vehicles, construction vehicles and distribution vehicles.

Eight,Shaanxi fast gearbox

When the vehicle is running, the higher the speed, the higher the power required. At this time, the performance of the gearbox is very tested. Because it is a heavy vehicle and the engine power is high, every shift will bring huge load to the gearbox.

Shaanxi Fast Group Co., Ltd. is China’s largest specialized production enterprise and export base with heavy-duty automobile transmissions, automobile gears and their forgings and castings as the main products. It ranks first in the national gear industry for six consecutive years, and the production and sales volume of heavy-duty gearboxes ranks first in the world.The strength is quite strong.

Ten,Universal gearbox

General gearbox is made by general motors, among which GM MT and AT gearboxes are also quite famous in the industry.The performance of the gearbox produced is still quite excellent.

What gearbox is the most durable and which brand of gearbox is good?

As for the answers to the above two questions, I’m afraid there is no accurate conclusion in the automobile gearbox in enter the dragon today. Because with the progress of science and technology, the durability and reliability of gearbox are improving.

According to relevant data, more than 99% of automatic transmissions have failed, which are basically caused by overheating and impurities in the lubricating oil of automatic transmissions.Therefore, if you want the gearbox to be durable and not prone to failure, then maintaining the gearbox and changing the gearbox oil are the key. If the owner’s vehicle vibrates greatly when shifting gears and the shifting speed is slow, it means that it is time to change the oil in the gearbox.

Automatic gear shifting car is not as simple as manual gear shifting car, and the manual gearbox is relatively simple in structure. Even if it is time to change the oil, it will not hurt to stay for a few more days, but the oil change of automatic gear shifting car can not be saved, and it will have to be changed after 20,000 kilometers. Otherwise, the car will be prone to problems and the gears will inevitably wear out over time.

Change the gearbox oil regularly, and the oil will "wrap" a protective film on the outer layer of each component of the gearbox, which will make the gear move more smoothly and stably. Finally, Xiaobian suggested,Generally, whether it is a manual gearbox or an automatic gearbox, it is best to change the gearbox oil every 12 months or 20,000 kilometers.

In recent decades, owning a car, and even riding in a Hongqi sedan, has become a status symbol. It was not until 2018 that the Hongqi car, which has the reputation of "national car", began to enter the homes of ordinary people. As the pioneer of new energy vehicles, it has become the focus of attention ever since. Everyone wants to see what are the differences in the enjoyment of this least similar EH7?

Since 2017, Hongqi has shouldered the important task of industrial revitalization entrusted by the times, and is determined to build a "China One, World Famous" car brand. Hongqi Motor holds high the brand concept of "Chinese-style new noble delicacy" and has created an industrial miracle with a growth of 65 times in 5 years, becoming a Chinese passenger car luxury brand with a value of over 100 billion yuan. Data show that in 2023, Hongqi Auto’s retail sales exceeded 370,000 units, an increase of 29.5% year-on-year, ranking first among Chinese brands in the fuel vehicle market above 150,000 yuan.

Not long ago, Hongqi’s first strategic model, Hongqi EH7, ushered in the launch. EH7 broke the convention of being held in closed venues in the past, and was held in an open manner, allowing the outside world to see the youthful, energetic and energetic side of Hongqi under the formal and solemn image of Hongqi. It can be said that the change of Hongqi is about to start with Hongqi EH7. Luxury face, technology lining, Hongqi EH7 has obviously done a good job of shouldering the heavy responsibility of the electric transformation of the Hongqi brand.

The EH7 is a medium and large-scale pure electric sedan that is the least like Hongqi. It is the first model under the new FMEs "flag" architecture of Hongqi. The front grille adopts a closed design, the newly designed "Flag Wonderful Wings" logo is inlaid above the grille, and the headlight group adopts a "7" shape design, which is very recognizable. The lower grille at the bottom presents a smiling style, and the overall shape is more youthful, without the shadow of the Hongqi fuel car at all. The overall upward tail shape, with a slippery back body, creates a strong sense of movement visually.

The smart cockpit is comfortable and stylish. EH7 adheres to the natural and smart design concept to create a three-dimensional staggered space layout; the suspended hollow design between the central control screen and the armrest creates a smart space level, and the overall appearance is light, fashionable, and more affinity; the seat adopts a four-layer structure of foam + soft bubble + skin soft bubble + skin, which is very comfortable to ride. The steering wheel and seat intelligence can be set according to the account memory, and the automatic return position brings convenience, comfort and exclusive experience to the driver and passenger.
