National CDC: When centralized or isolated at home, it is not allowed to lock the door outside.

  On the afternoon of September 29th, the State Council Joint Prevention and Control Mechanism held a press conference to introduce the situation of epidemic prevention and control during the National Day and answer questions from the media.

  Lei Zheng Long, director of the Department of Communication and Prevention of the National Bureau for Disease Control and Prevention, said that since the outbreak of COVID-19, we have always adhered to the principle of "people first, life first", guiding all localities to conscientiously implement the requirements of relevant prevention and control policies and measures, do a good job in accurate prevention and control, strengthen the prevention of safety risks, and earnestly safeguard the life safety and health of the broad masses of the people.

  One is in nucleic acid detection. All localities are required to reasonably organize and arrange nucleic acid inspection for the masses to avoid gathering and chatting. When people take part in nucleic acid testing, they should pay attention to personal protection, keep a straight line, wear masks and do good hand hygiene. All localities should also make reasonable arrangements for sample transfer vehicles, which should not be used for other purposes during the transfer task.

  The second is in the process of flow adjustment and transshipment. It is required that all localities should strengthen on-site face-to-face flow adjustment, and the flow adjustment personnel should also do personal protection, and scientifically and accurately determine the risk personnel such as close contacts, close contacts, and exposed personnel in epidemic-related places. Make overall arrangements for the deployment of transshipment, formulate a transshipment plan in combination with local actual conditions, reasonably arrange transshipment tasks and transshipment time, strengthen the daily inspection and safety maintenance of transshipment vehicles, improve the safety awareness of drivers and passengers, put an end to drivers’ fatigue driving and ensure transshipment safety.

  The third is in the centralized isolation link. The infrastructure of centralized isolation places should meet the current national standards for building safety, fire safety, earthquake prevention and disaster prevention, strictly regulate the management of isolation points, and prevent cross-infection. For special people who are not suitable for centralized isolation after evaluation, measures of home isolation can be taken. For those who are not suitable for single room isolation, appropriate personnel should be appointed to accompany them.When centralized or home isolation measures are taken, it is not allowed to lock the door outside.

  The fourth is the supply of living materials, medical care and other links. After the outbreak, all localities should scientifically and accurately define the risk areas and make dynamic adjustments, strictly implement management requirements according to regulations, and make clear that special personnel teams are responsible for the supply of basic living materials for residents, especially to prevent food safety incidents. It is necessary to designate specialized medical institutions to provide medical services for residents in high-and medium-risk areas and provide medical convenience for special people.

Iranian Rouhani under US sanctions: Unity will make Americans regret it.

  CCTV News:On August 6, US sanctions against Iran came into effect again. Bloomberg pointed out that under this round of sanctions, Iran’s economy is close to the brink of crisis. The Iranian currency Rial has been falling all the way, and domestic grievances have accumulated. In recent days, people’s demonstrations broke out in the streets of Tehran, Isfahan, Hamadan and other cities in Iran.

  Iranian young people satirize the current domestic problems in Iran on social media. The Iranian youth showed that the Iranian currency Rial with a denomination of 10,000 was rapidly shrinking. In the shadow of sanctions, the Iranian currency Rial plummeted. People have expressed their dissatisfaction.

  Iranian peoplePeople have the right to protest that economic and social problems are all related, and how much more can we bear when people are under great pressure.

  Iranian protestersLet’s build our country with our hands. Don’t be afraid, as long as we unite with domestic and foreign forces.

  Rouhani’s government is under unprecedented pressure, and Rouhani himself is constantly being questioned by the Iranian parliament. Qatar Al Jazeera commented that the United States hopes that Iran will achieve regime change through civil strife.

  US Secretary of State PompeoIt’s time for the Iranian regime to look in the mirror. The Iranian people urgently need economic, political and social changes.

  According to the British "Guardian" report, the United States has close contacts with Iranian opposition organizations in exile. Rajavi, leader of the exiled Iranian opposition "People’s Mujahideen Organization of Iran" (MEK). She advocates regime change in Iran. It is reported that US national security adviser Bolton met with Rajavi in Paris in 2017 and said that the United States supports regime change in Iran and hopes to reunite with the organization in 2019. Some media have linked this time of the ultimate sanctions to be introduced by the United States in November with the date of 2019.

  The Guardian noted that the Iranian People’s Mujahideen Organization has long been listed as a terrorist organization by Iran, the United States, Canada and the European Union. According to the statistics of the US Department of Justice, since the Iranian revolution in 1979, terrorist attacks in MEK have caused at least 10,000 civilian deaths. On August 7th, Iranian President Rouhani responded.

  Iranian President RouhaniI think if we can unite as one, we can make Americans regret it soon. If we can successfully cooperate well with other countries in the world, Americans will realize that their sanctions are ineffective and will come back sooner. "

  In response to people’s demands, the Rouhani administration arrested the deputy governor of the Iranian central bank in charge of foreign exchange, and stopped buying non-essential goods to reduce the consumption of foreign exchange.

  Facing the most influential oil trade, the Rouhani administration lifted the state monopoly on oil trade and allowed private channels to buy and sell oil, because the US sanctions mainly targeted Iranian government agencies and officials.

  In the transactions with Turkey, India and some African countries, the US settlement is circumvented by barter or local currency settlement. Iranian businessmen also evade sanctions by purchasing overseas nationality and registering companies overseas. The external pressure from the United States has also made many political elites and people vigilant.

  Tehran citizen AryanTrust in America will lead to nothing but failure. We must rely on our own strength.

Hong Kong mob pistol has a mystery: American rough assembly can not be traced back to the source, and it is easy to frame the police.

[Text/Observer Network Wang Shichun]

On December 8, Hong Kong police seized a large number of dangerous weapons, including a compact glock)19/23 pistol and 105 rounds of ammunition. The bullets of this type of pistol are basically the same as those of the active pistol of the Hong Kong Police.

Military commentators of Observer Network judged that this gun was not a legitimate gun produced by Glock’s original factory, but a "black gun" assembled by American manufacturer Polymer80 products, without any logo, number and ballistic record. Although the product sold by Polymer80 is a semi-finished blank, the gun body has been processed to 80%, and the mob may smuggle the rest of the parts "processed with materials" and finally assemble this black gun.

If the mob used this gun to open fire in the crowd, then the Hong Kong police could not produce the ballistic record of this gun in the subsequent investigation. Today, with the intensification of conflicts in Hong Kong, if the Hong Kong police can’t produce ballistic records for a long time, it is bound to be framed by mobs and put the Hong Kong police at a disadvantage.

The real guns and magazines seized are from Hong Kong media.

Hong Kong TVB TV reported on December 8 that 75 police officers from the Organized Crime and Triad Bureau of the Hong Kong Police raided 11 addresses in Hong Kong and smashed a criminal gang in the early morning of the 8 th. During the illegal assembly in Mong Kok on October 20th, the gang used petrol bombs to attack the Mong Kok Police Station.

In the end, the Hong Kong police seized a large number of dangerous weapons in the mob’s home, including a compact glock)19/23 pistol and 105 bullets. Among them, three magazines are full of bullets. Li Guihua, Senior Superintendent of the Organized Crime and Triad Bureau, said that the Hong Kong Police Force had received a tip earlier that "(this gang) plans to use firearms to create chaos in today’s assembly and procession, including shooting police officers or framing police officers to hurt passers-by".

After studying by military commentators of Observer Network, the mob has a "black gun" modified from Glock 19/23 blank made by American manufacturer Polymer80.

Made by American manufacturer Polymer80, the blank of Glock 19/23 Source: Polymer80 Company official website.

Polymer80 is a company specializing in the manufacture of rough firearms within the scope of "permitted by American law". The rough produced by the company can circulate freely in the market without registration even if there is no serial number.The company’s pistol is characterized by no marks, numbers and ballistic records. The Hong Kong police can’t find available information through the ballistic records and serial numbers of firearms.Only through time-consuming and laborious criminal investigation can the source of guns be traced back.

It is worth mentioning that when Polymer80 sells gun blanks, it not only includes rough blanks, but also small parts, clamping fixtures and necessary drill bits. On the official website of Polymer80, there are also documents that teach you how to process it step by step to the usable level.

Glock in the hands of thugs is a product numbered PF940C. Although it is a rough imitation of the compact Glock 19/23, the machining degree has reached 80%, and all the basic parts of the sleeve seat have been machined, while the sleeve, trigger and barrel are sold separately.

When Polymer80 sells gun blanks, it not only includes blank, but also small parts, clamping fixtures and necessary drill bits. Source: Polymer80 Company official website.


The sleeve seat set is priced at $160, and another sleeve and barrel with high completion is priced at $450, but it shows that it is out of stock. Source: Polymer80 Company official website.

Glock pistol is one of the largest selling pistols in the world, so the parts of this pistol are not hard to find. In Southeast Asia, where gun crimes are frequent, many small weapons factories also independently produce the whole gun and parts of Glock pistols. Mobs may use parts smuggled from abroad to assemble a "black gun" without any marks, numbers and ballistic records.

The underground gun workshop in the Philippines is producing the American-made M1911 pistol, but it is not difficult to produce Glock’s parts.

The Hong Kong police displayed the captured Tatsu Yamashiro map from social media

At present, the Hong Kong police have two types of Glock, namely glock 17 and Compact Glock 19, which are currently used by the Hong Kong Police Small Boat Division (Maritime Emergency Response Team), Witness Protection Team, vip protection unit, Tracking Support Team, Airport Special Police Team, Railway Emergency Response Team, Counter-Terrorism Special Service Team and Special Task Company.

Due to the formal introduction channels, every Glock pistol of the Hong Kong police has a clear ballistic record.

Gun experts told Observer.com that if the mob framed the Hong Kong police with this gun, the Hong Kong police could not produce the ballistic record of this gun in the follow-up investigation. Today, with the intensification of conflicts in Hong Kong, if the Hong Kong police can’t produce ballistic records for a long time, it is bound to be hyped by mobs and framed at a disadvantage.

The Hong Kong police are investigating the purpose of the mob holding a gun. Li Guihua said that this is the first time that the Hong Kong police have seized real guns since the "chaotic demonstrations in Hong Kong", so they are very nervous. The source of this real gun will be one of the focuses of the Hong Kong Police Force’s close investigation in the future.

He stressed that this pistol is not a specification used by the Hong Kong Police Force. When someone asked at the press conference whether the perpetrators tried to frame the plainclothes police in Hong Kong this time, Li Guihua said, "I dare not say more now."

Hard-core New Choice Try SAIC MAXUS D90 Pro Diesel Edition

  [car home Original Test Drive] On April 10th, SAIC MAXUS D90 Pro (abbreviated as D90 Pro in the text) was officially launched, and there were seven new models with the price range of 179,800-279,800 yuan. In fact, this car was unveiled at the Guangzhou Auto Show last year and accepted the reservation. After more than four months, it finally came. We also conducted a field test drive for this car at the first time. Compared with our AH-100 professional test site, the off-road test site is not difficult. Surely such a simple "test" can’t help this "tough guy" who is good at off-road?

Home of the car

  The test drive of the SAIC MAXUS D90 Pro is equipped with a 2.0T diesel engine and matched with the 8AT automatic manual transmission. As a modified model of SAIC MAXUS D90, this car has also been given a brand-new naming method. The appearance of the word Pro makes us look forward to the improvement of its strength.

● Test drive models

  Although it is said that there are seven models on the market, in fact, there is no fixed configuration version of the D90 Pro. The "recommended models" and prices are only for reference. Users can determine the configuration they want through the wise selection of SAIC MAXUS Spider, and specifically customize their favorite models.

● The appearance is masculine.

  The body size of the D90 Pro is relatively large, which also determines that it is "born" with a strong gas field. The hexagonal mesh shape looks a bit exaggerated, but at present, "big mouth" is also a popular design style. For most users who choose the D90 Pro, they definitely bought a car to go out in the wild, so it is more important to choose a set of off-road kits. The off-road kits provided by SAIC MAXUS for the D90 Pro include original 18-inch off-road tires, wading throats, bottom off-road fenders, off-road wheel eyebrows and sand barriers, etc. The D90 Pro equipped with these kits is like an athlete in a competition suit, and its heroic spirit is compelling. It’s a little pity that we didn’t assemble all the off-road kits for this test drive.

  Compared with the competitors of the same level, the body size of the D90 Pro does not fall in the wind, and the wheelbase length is obviously superior to that of the competitors of the same level. As a car with off-road capability as its selling point, the passability is a very important indicator. The minimum ground clearance of D90 Pro is 210mm, and the maximum wading depth is 800 mm. The low point of the chassis uses a waterproof one-way valve, and the approach angle is 28, and the departure angle is 25, so it will not easily rub when facing complex road conditions.

  The design style of the interior is quite fashionable. When you only look at the interior, it is hard to imagine that this is a medium-sized off-road vehicle. The silver decorative strips in the details, the large-area suede material coverage and the 12.3-inch central control screen all show you: "Although I am big, I can be exquisite."

  The 12.3-inch central control screen is not so big in the current trend of big screen popularity. It feels just right on this car, and the clarity of the screen and the fluency of the system response are good. SAIC Ali Zebra Zhixing system can be said to be an "old friend" of everyone. Now this system has been upgraded to version 3.0, with more and more functions, including voice control, music, navigation, remote control of vehicles and other functions. The original car is also equipped with a high-tech navigation map.

  The seat configuration of this test drive model is quite high. With the help of Spider Smart Choice, the rich seat functions are no longer exclusive to the top model. Users can customize their favorite configurations according to actual needs, and the diversified seat layout forms also give consumers more choices.

● Summary

  In fact, there is not much to describe about the static part. The exterior design and interior design are two separate things, and it is most important for users who really want to buy a car to look pleasing to the eye. The spider intelligent selection function launched by SAIC MAXUS has raised the user’s independent choice to a new height. This intelligent customization service provides nearly 100 choices including powertrain, seat form, appearance kit, interior material and configuration equipment, and can directly place orders with the factory, and can also track the manufacturing status of the vehicles it has ordered in real time. With this feature, you will avoid a lot of time entangled in the configuration table.

  The 2.0T diesel engine mounted on the D90 Pro is named SAIC π (meeting the national VI b emission standard). This engine adopts two-stage supercharger, which can exert the maximum value of turbocharging under different load intensities, and has obvious effect on improving the low-speed torque of the engine. In addition, the friction work of the piston at medium and low speed is reduced by staggering the crankshaft centerline and the cylinder bore centerline, which is beneficial to improving fuel economy and reducing noise.

  The so-called all-terrain intelligent timely four-wheel drive system is actually several torque output forms calibrated by manufacturers according to different road conditions and the conclusion of road test. If you are a "super hard core" cross-country player, you can also choose to install the part-time 4wd system. In terms of gearbox setting, this gearbox will not shift up automatically in manual mode, so as to ensure stronger torque output in low-speed gear and cope with more complicated off-road conditions.

  The D90 Pro has smooth power and sensitive throttle adjustment. Although the size of the whole vehicle is not small, it doesn’t feel heavy when driving, and there will be no hesitation even when completing cross-country projects. During the test drive, for safety reasons, parking on the slope is not allowed at the site, so there is no difficulty in completing the climbing project (about 40 slope).

  The overall texture of the chassis is relatively compact, the support effect of the suspension is good, it is somewhat tenacious, and the handling of bumps on the road surface is relatively simple. When walking on the continuous undulating road surface, the rear suspension has no obvious redundant ricochet, and there will be no feeling like sailing. The steering system in the form of electronic power is exchanged for a lighter steering feel, and driving in daily urban traffic environment will not feel tired.

  Two "opponents" were also found at the scene, and I experienced Haval H9. The overall feeling of Haval H9 is more "tight". From the chassis texture to the steering feel to the feeling of the accelerator pedal, H9 is more "hard", but the low-torque dynamic performance is better than D90 Pro. Like an athlete on the basketball court, H9 is like a center, heavy and slow, but as long as the action is in place, it must be an effective action; The D90 Pro is more like a power forward, with more agile performance and richer actions and means of "scoring". The setting of each project in the off-road test drive venue is relatively simple, and both cars can pass easily, so it is impossible to tell the absolute advantages and disadvantages in this competition.

● Summary

  SAIC MAXUS D90 Pro is a car with high attention, which can be seen from the fiery degree of car home Forum. Through the spider intelligent selection function, users can have a high degree of "autonomy", which is undoubtedly a good thing. A short field test drive can’t have a deep driving experience for this car, but as far as the test items in the field are concerned, no one can stand the D90 Pro hard, which can also prove that the off-road ability of the D90 Pro is really good. Next week, we will welcome the D90 Pro test car. At that time, we will pull it to a professional off-road field in car home for the AH-100 off-road test, and then we will see how its "real strength" is. (Text/map/photo by car home Fu Bo)

Experts’ Interpretation of the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial)

  In order to protect the marine environment and promote the work of marine environmental standards, the Ministry of Ecology and Environment issued the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial) (HJ1260—2022) on July 18, 2022 (hereinafter referred to as the Guide). This is the first standard to guide and standardize the derivation of marine environmental standards in China, and relevant experts have answered relevant questions.
  Q: What is the significance of the publication of the Guide for China’s marine environmental protection?
  Researcher Yao Ziwei of National Marine Environmental Monitoring Center: Marine environmental benchmark is an important part of modern ecological environment governance system, and it is the basis and scientific basis for formulating China’s marine ecological environment quality standards, which can provide important support for China’s marine ecological environment risk assessment and emergency response.
  The current Standard for Seawater Quality (GB3097—1997) has played an important role in the prevention and control of marine pollution in China, but when the standard was first formulated, it was based on one or more foreign seawater quality standards (marine life, senses, health, etc.). As for marine biological water quality standards, there are great differences between different countries and even the same country in different periods due to the differences in derivation methods and concerned species. When conditions permit, countries should carry out relevant benchmark research according to their own marine ecological environment characteristics.
  The publication of the Guide is of great significance for strengthening the research of marine environmental standards in China, accelerating the transformation and application of research results, and improving the level of marine ecological environmental protection.
  Q: Since the 1980s, some developed countries and international organizations have successively issued water quality standards for marine organisms. In contrast, what are the unique features of the Guide in terms of methods and technical requirements?
  Researcher Wang Ying, National Marine Environmental Monitoring Center: Since 1980s, the environmental management departments of the United States, the European Union, the Netherlands, Australia/New Zealand and Canada and other countries and international organizations have successively issued technical guidelines for deriving water quality standards for protecting aquatic organisms (freshwater organisms and marine organisms) and water quality standards for protecting marine organisms according to their environmental management needs and water pollution status. In the process of compiling the Guide, domestic and foreign scientific research achievements were fully absorbed and used for reference.
  Methodologically, it is stipulated that the species sensitivity distribution method is used to derive the water quality standards of marine organisms, which is the mainstream method to derive the water quality standards of freshwater and marine organisms in the world at present, and it is also the method stipulated in the Technical Guide for Deriving Water Quality Standards of Freshwater Organisms (HJ831—2022).
  In terms of technical requirements, the characteristics and working basis of China’s marine ecosystem are fully considered: first, the toxicity data of marine species in China are required to be used to derive the water quality standards of marine organisms; Secondly, according to the species distribution of marine ecosystems in China, the minimum toxicity data requirements of "5 families and 8 species" based on the characteristics of marine biota in China are put forward; Thirdly, the calculation method of acute value/chronic value of the same effect is proposed, which solves the problem that different types of toxic effects have different weights and achieves the purpose of better protecting marine species in China. At present, only the European Union has put forward this technical requirement internationally.
  Q: How to consider the minimum toxicity data requirements of "8 species in 5 families" based on the characteristics of marine biota in China?
  Yan Zhenguang, researcher of china environmental science Research Institute: According to statistics, there are more than 3,000 species of microalgae and macroalgae in China, accounting for 11% of the total marine species in China; Arthropoda, Chordata, Annelida, Mollusca, Echinoderm and Rotifera are the main animal groups in China’s sea areas, with more than 17,000 species, accounting for 59% of the total marine species in China. The number of marine species in the above key groups of marine life in China accounts for more than 70% of the total marine species in China.
  In order to make the derivation of marine biological water quality benchmark reflect the characteristics of marine ecosystem in China, it is a basic principle to determine the minimum toxicity data requirements for the derivation of the benchmark. The tested species in seawater should cover the key groups of marine organisms in China, which is embodied in the following aspects: 1 family of microalgae or macroalgae, 2 families of crustaceans in Arthropoda and 1 family of bony fishes in Chordata; Other phylum, such as annelids, molluscs, echinoderms, rotifers, etc., or an unused family among crustaceans and teleost fishes.
  The minimum toxicity data requirements of 8 species are mainly considered from the following two aspects: from the point of view of mathematical statistics, the more species, the better the model effect; From the point of view of the robustness of species sensitivity distribution model and the reliability of reference value, if the toxicity data covers key biological groups, then the uncertainty of reference value based on more than 8 species is within the acceptable range. There are eight criteria for evaluating the number of species as "good" in the minimum toxicity data requirements of the Australian/New Zealand Technical Guidelines for Derivation of Water Quality Standards.
  At the same time, from the perspective of protecting marine biodiversity and marine ecology, it is clear that alien invasive species should not be used as a benchmark to deduce the tested species, such as marine microalgae that produce microcystins and Spartina alterniflora that compete with native species for nutrition.
  Q: We have noticed that there are great differences in the exposure time of different kinds of marine life in the Guide. How do you consider it?
  Professor Tan Qiaoguo of Xiamen University: Based on the standard testing methods of marine ecotoxicology at home and abroad, in order to protect marine species in China more pertinently, on the basis of analyzing the life history and reproductive characteristics of different types of marine species, the Guide puts forward the differential exposure time for 7 categories and 43 families of marine organisms such as algae, rotifers, annelids, molluscs, arthropods, echinoderms and chordates. According to the acute toxicity test, the generation cycle of Brachionus plicatilis is only about 2 days, and it is recommended that its exposure time should not be longer than 48 hours. For most arthropods and fish, the generation cycle is long, and the exposure time is recommended to be no more than 96 hours. According to the chronic toxicity test, the generation cycle of cladocera such as Daphnia mongolica is 5-7 days, and the exposure time is recommended to be no less than 5 days. However, the generation cycle of fish such as medaka can reach 3-4 months, and it is recommended that its exposure time should be no less than 21 days.
  Q: As the vice chairman of the National Expert Committee on Environmental Standards, I would like you to talk about what work needs to be promoted in the field of marine environmental standards in China during the 14 th Five-Year Plan period.
  Researcher Wang Juying, National Marine Environmental Monitoring Center: Marine environmental standards mainly include marine biological water quality standards and sediment quality standards for protecting marine ecosystems, nutrient standards for preventing water eutrophication, and people’s health standards for consuming seafood and marine recreational water.
  China’s marine environmental benchmark research began in 1980s, and made some progress. For example, related research provided direct technical support for the formulation of Marine Sediment Quality (GB18668—2002); The national "863" special project "Research on Key Technologies for Determining the Threshold of Marine Environmental Effects of Typical Organic Pollutants from Land-based Sewage Discharges into the Sea" and the marine public welfare scientific research special project "Research and Formulation of Offshore Seawater Quality Standards/Standards" won the first prize and the second prize of the Marine Engineering Science and Technology Award respectively.
  China’s sea area spans temperate zone, subtropical zone and tropical zone, and the marine ecosystem is diverse. From the perspective of protecting China’s marine ecosystem, during the Tenth Five-Year Plan period, based on protecting the integrity of China’s marine ecosystem, we should speed up the research and construction of China’s seawater quality benchmark system, develop the target pollutant marine biological water quality benchmark that has an important impact on China’s marine ecological environment quality, carry out the ecological risk threshold research of new pollutants such as endocrine disruptors, and develop the nutrient water quality benchmark of key sea areas such as Bohai Sea and South China Sea based on classification and zoning.
  Experts in the field of marine environmental benchmark research in China are distributed in different institutions. In order to ensure the smooth progress of the marine environmental benchmark work in the 14th Five-Year Plan, we should give full play to the role of the National Environmental Benchmark Expert Committee as a think tank platform, and the superior research teams in the United Nations should work together to organize joint research.

  This world’s most advanced train passes through the foot of Badaling Great Wall and runs side by side with Beijing-Zhangjiakou Railway more than 100 years ago.

  A century’s span, two Beijing-Zhangjiakou lines, witnessed the course of Chinese from designing and building its first "road to success" to becoming a "pioneer" in opening intelligent high-speed rail.

  As a symbol, China’s high-speed rail mileage has exceeded 35,000 kilometers, and the Chinese nation has built new glory on the great journey of national rejuvenation.

  On December 30th, a Fuxing train was running in Xiahuayuan District, Zhangjiakou City, Chongli Railway. On the same day, Chongli Railway and Beijing-Zhangjiakou High-speed Railway were opened simultaneously. Xinhua news agency

  A century’s leap to achieve "the country of high-speed rail"

  There is a bronze statue of Zhan Tianyou at the foot of the Great Wall and next to Qinglong Bridge Station surrounded by green hills in Yanqing District, Beijing.

  As the founder of the Beijing-Zhangjiakou Railway, he looks far away, and his profound eyes seem to have penetrated the great changes of a century … …

  In 1905, the Beijing-Zhangjiakou Railway started construction. Badaling tunnel with a total length of 1091 meters is the key project of Beijing-Zhangjiakou Railway. At that time, there was not a trunk railway designed, built and operated independently by Chinese people in our country. Foreign engineers boasted that the engineer who could repair the Beijing-Zhangjiakou Railway in China had not yet been born!

  Zhan Tianyou, who returned from studying abroad, broke this argument. He applied the herringbone railway used for logging in South America to the trunk railway in China for the first time. By extending the distance, he successfully passed the 33 rd & Permil; The steep slope shortens the Badaling tunnel, which originally needed to be excavated for more than 1,800 meters, to 1,091 meters.

  Today, the Beijing-Zhangjia high-speed railway passes under it. Yang Cunxin, the stationmaster of Qinglongqiao Station, said that this is a "handshake" between the Beijing-Zhangjia high-speed railway and the old Beijing-Zhangjia railway, which symbolizes the development speed of China, and has achieved the three-dimensional intersection of Beijing and Zhangjiakou in the past century.

  "In ‘ Zhan Tianyou ’ When you work under your feet, you must do a fine job. " Jiang Si, project manager of Beijing-Zhangjia High-speed Railway of the Fourth Company of China Railway Fifth Bureau Group, said.

  Badaling Great Wall Station, which he is in charge of, is the only underground station of Beijing-Zhangjia high-speed railway, and it is also the largest underground station of high-speed railway in the world at present. When the project is repaired to the bottom of Qinglong Bridge Station, it is only 4 meters away from the ground, and it is necessary to ensure the normal running of the train above.

  After a century’s leap, the railway construction in China has experienced the internal combustion engine era and the electrical era from age of steam in Zhan Tianyou, and quickly entered the high-speed rail era.

  More than 100 years ago, the Beijing-Zhangjiakou Railway was the first section of beijing-baotou railway. From Baotou to Beijing by train, the train has to walk slowly for one night to get to Qinglong Bridge Station, and it will take half a day to get to Beijing after changing the front of the train here.

  "After the opening of the Beijing-Zhangjia high-speed railway, the Zhanghu high-speed railway will be opened to traffic simultaneously with the Dazhang high-speed railway, and it only takes more than an hour to take the high-speed railway from Zhangjiakou to Beijing. After the Beijing-Zhangjia high-speed railway is connected with Zhanghu high-speed railway and Dazhang high-speed railway, the Inner Mongolia prairie will be realized in Beijing-Tianjin-Hebei region. One-day tour ’ 。” Huang Xin, director of the passenger transport department of China National Railway Group Co., Ltd. said.

  The more the road network is woven, the more convenient the trip is. In December 2019, more than 10 railways including Beijing-Zhangjia high-speed railway were intensively opened.

  China seems to be "small" — — The formation of the "meter" railway network in Henan, the ring-shaped high-speed railway in Shandong, the through train in Jiangxi, and the continuous extension of the "eight vertical and eight horizontal" high-speed railway main channel in China … …

  People’s dreams have become bigger — — High-speed rail is vertical and horizontal, "say and go", and the travel radius of the people extends with the expansion of the "high-speed rail economic circle".

  "More than one hundred years ago, my great-grandfather built the Beijing-Zhangjiakou Railway. Today, I personally took the Beijing-Zhangjia high-speed rail. I believe that if his old man is alive in heaven, he will be as proud and proud of the achievements of the country and the nation as I am. " Zhan Tianyou’s granddaughter Zhan Xin told reporters.

  Leading by innovation, creating a "road of wisdom"

  "Smart" is the most beautiful label of Beijing-Zhangjia high-speed railway.

  The "Fuxing" intelligent EMU running on the Beijing-Zhangjia high-speed railway can drive by itself.

  "The train has added ATO-related equipment for automatic operation control, realizing automatic driving with people on duty in the whole process, redefining the operation mode of the train." Zhang Bo, deputy director and researcher of the Locomotive and Rolling Stock Institute of the Academy of Iron and Steel Sciences, said.

  According to the precise operation plan pre-planned by the ground dispatching center, the "Fuxing" intelligent EMU can automatically control the departure, acceleration, deceleration and parking. During the whole traveling process, the intelligent train safety monitoring system carried by the EMU has more than 2,000 monitoring points, which comprehensively monitors the state of the EMU in real time, and realizes self-perception of working state, self-diagnosis of running faults and self-decision of guiding safety.

  In the past century, from the steam locomotives of Beijing-Zhangjiakou Railway, to diesel locomotives, to electric locomotives, and then to the Harmony and Fuxing EMUs, the changes of locomotives and trains reflect the increasing scientific and technological innovation strength of China.

  Zhang Bo said that the "Fuxing" intelligent EMU was developed on the basis of the "Fuxing" with a speed of 350 kilometers per hour. In the design, it is considered that it is necessary to adapt to the line conditions of Beijing-Zhangjiakou high-speed railway and meet the service needs of the 2022 Beijing Winter Olympics.

  At the bottom of the "Fuxing" intelligent EMU, there are two square boxes about 9 square meters. They are energy storage battery packs, which are usually charged by vehicles when running. When the catenary has power failure, they provide power for vehicles to ensure smooth arrival at the nearest station.

  "Fuxing" intelligent EMU has superior aerodynamic performance and beautiful appearance. In terms of humanized service, intelligent environment awareness adjustment technology has been added, which can realize the adjustment of temperature, lighting and window color, and further improve the ride comfort. The whole vehicle is covered by wifi and equipped with a multilingual passenger information system, which can meet the needs of international passengers. The seat is installed in a slide way, allowing more wheelchairs to be added.

  "Some carriages also add ski equipment storage cabinets for skiers to store snowboards and other equipment. The ski equipment lock identified by QR code is convenient and safe. " He said.

  As the first intelligent high-speed rail in China, the quality supervision, supply, profile design and polishing of each rail of Beijing-Zhangjiakou high-speed rail also used big data and established a "health file".

  According to the technical director of China Railway Materials Group, in the rail production process, they set up a data file for each rail. After the high-speed rail is put into operation, the "healthy" state of the whole rail line can be grasped by analyzing and studying the data, and the rail life cycle management can be realized.

  Fan Yijiang, deputy director of the Comprehensive Research Office of the Comprehensive Transportation Research Institute of the National Development and Reform Commission, said that in the past 10 years, the changes in China’s high-speed rail have amazed the world. From a series of Harmony motor trains flying across the country to Fuxing leading the world standards, China high-speed railway has continuously created remarkable achievements.

  Work hard and realize dreams, paving the way for "revival"

  In 2022, Beijing Winter Olympics, visitors from all over the world will be able to take the Beijing-Zhangjia high-speed rail.

  A hundred years ago, Zhan Tianyou wrote that "it is a shame to steal that our country is vast in territory and abundant in natural resources, but we have to rely on outsiders for our work along the way", and encouraged ourselves to lead the Chinese people in designing and building railways. However, the Beijing-Zhangjiakou Railway has not completely got rid of the fate of "relying on foreigners".

  At that time, there was hardly any manufacturing industry in China, so it was impossible to produce the relevant equipment needed by the railway.

  "Although the design and construction of the Beijing-Zhangjiakou Railway was completed by Chinese, all parts of the railway, even every nail, were imported from abroad." Gu Lin, secretary of the transfer workshop branch of Tangshan South Railway Station, said.

  "Engineers are beneficial to the skills of the country. They should learn from each other and know everything, so that the country will be rich and strong, free from foreign aggression, and stand on its own feet on the earth." This was Zhan Tianyou’s profound understanding of building a road power 110 years ago, and it was also the cry of all Chinese at that time. The railway spirit of learning from each other and pursuing excellent products has since led generations of railway people to embark on the road of building dreams.

  A hundred years later, China Railway has already entered the era of autonomy. Based on Beidou satellite and GIS technology, the designer deployed a "positioning" large network in Beijing-Zhangjia high-speed railway, which can provide intelligent services for the whole process of construction, operation, dispatching, maintenance and emergency by using the high-precision map of the railway.

  "In the future, there will be the same ‘ Brain ’ 。” Hong Xia Li, the overall person in charge of intelligent engineering design of Beijing-Zhangjia high-speed railway designed by China Railway, said that through this brain, the staff can manage the lighting, temperature, humidity and other equipment in the control room, and conduct emergency command.

  A century-old Beijing-Zhangjia bears Chinese’s dream of rejuvenation and the feeling of strengthening the country. The reconstruction of Beijing-Zhangjiakou is erecting another monument to railway power and national rejuvenation.

  On the "report card" of the Institute of Iron Science, there is a sentence: Among the 254 important standards adopted by Fuxing, China standard accounts for 84%, and the overall design and key technologies are all independently developed, with completely independent intellectual property rights.

  Relying on the construction of Jing-Zhang high-speed railway, China will further form a demonstration scheme of intelligent high-speed railway application, build a technical standard system of intelligent high-speed railway, and become a world-leading intelligent high-speed railway application country.

  "The Beijing-Zhangjia high-speed railway has attracted worldwide attention, but this is not a miracle created by builders. It was a great era and the development of the motherland that created this miracle. " Lv Gang, deputy chief designer of Beijing-Zhangjiakou Railway Project designed by China Railway, said.

The change of village "two committees" nationwide was successfully completed.

  Xinhua News Agency, Beijing, May 22nd  Title: Build a battle fortress for comprehensively promoting rural revitalization — — The change of village "two committees" nationwide was successfully completed.

  Xinhua news agency reporter

  If the nation is to be revived, the countryside will be revitalized; To revitalize the countryside, the "leading geese" must be strong.

  In October 2020, the term of office of the village "two committees" was changed from three years to five years, and the first change of office was started in 31 provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps, which was carried out simultaneously with counties and townships. At present, 491,000 village teams across the country have successfully completed the transition.

  The cadres and the masses generally reflected that the change was strict, vigorous, positive and effective, and they chose to be a good team, which changed the situation of stability and unity, formed a good atmosphere for entrepreneurs, and solidly built a fighting fortress for comprehensively promoting rural revitalization.

  Strengthen organization and leadership, and compact the responsibility of the change of work layer by layer.

  The leadership of the party is the key to do a good job in the transition.

  The CPC Central Committee and the State Council attached great importance to the change of the village’s "two committees". General Secretary of the Supreme Leader made important instructions for many times, went deep into the village for investigation when visiting relevant places, raised ardent hopes for village cadres, and cared for party member and the masses, which pointed out the direction and set an example for party committees at all levels to earnestly fulfill their responsibilities of managing the party and the party and carefully organize the change.

  The Organization Department of the Central Committee and the Ministry of Civil Affairs conscientiously implement the spirit of the important instructions of the Supreme Leader General Secretary, and guide and promote all localities to do a good job in the village "two committees" change. Party committees and governments at all levels shoulder their responsibilities and pay close attention to reality, ensuring the successful completion of this general election and achieving the expected purpose.

  "The cadres in the county towns often come to the village, and the policy and discipline of re-election are household names." Liu Rongwen, the leader of Kewang Village, Shijiao Town, Fogang County, Guangdong Province, said that after the re-election work was carried out, cadres would come at night when they were not available during the day and at weekends when they were not available on weekdays, patiently preaching policies and guiding work.

  In order to compact the responsibility, Fogang County set up a leading group and office for the change of work headed by the county party secretary; The whole county implements the mechanism of leading cadres’ joint responsibility for villages, and 29 county leaders "stick their hands in the end". Every week, they lead teams to sink villages (groups) to analyze and judge the truth, investigate and resolve contradictions, and publicize the discipline of change.

  All localities strengthen the leadership of the Party, give full play to organizational advantages, and do all the work in detail to ensure the smooth and smooth progress of the general election. Thirty-one provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps have set up a new leading group headed by Party secretary, deputy secretary or organization minister, and established a working mechanism in which the organization department takes the lead in coordination, the civil affairs department cooperates closely and the relevant departments participate together. Party Committee secretaries of Beijing, Tianjin, Shanghai, Guangdong, Chongqing, Xinjiang and other provinces and cities all went deep into the village to investigate, regularly listened to the change of office and promoted the work to be carried out in a solid manner.

  At the same time, all localities generally implement the guidance and promotion mechanism that provincial leaders contact cities, counties, municipal leaders Bao County Lian Xiang, county leaders Bao Xiang Lian Cun, township (street) cadres and resident cadres, especially to promote the secretary of county and township party committees to firmly grasp the change of office.

  "We have fully implemented the system of hanging points and linking. The city leaders have covered 90 counties (cities, districts), and more than 3,000 county-level leadership team members have fully covered the countryside, from the preparation work to the completion of the whole change." The relevant responsible comrades of the Organization Department of Zhejiang Provincial Party Committee introduced that the leaders of Baolian County, the leaders of towns and streets, and the "three-person group" of resident cadres provided all-round guidance.

  In Weishan Yi and Hui Autonomous County, Yunnan Province, the township party committees have accurately identified the operation of the team, the current situation of party member, the reserve of candidates, the demands of the masses, potential risks, etc., so as to make the base clear and the election clear; At the same time, party member cadres from counties, townships (towns) and villages held mass meetings in 1341 villagers’ groups throughout the county to ensure that the work covered every branch, every party member and the masses.

  The organization and leadership are strong, and the transition work is carried out in an orderly manner. All localities adhere to the unity of the party’s leadership, promote democracy and act according to law, adhere to the combination of goal orientation, problem orientation and result orientation, organize and implement with high standards and quality, and implement a series of effective measures throughout the process of re-election.

  "Going deep into the water" selects talents and makes "good seedlings" stand out.

  In Chudun Village, luozhuang, Linyi City, Shandong Province, baskets of vegetables are being sealed and packed on the assembly line. Yu Zhang, a retired soldier born in 1991, returned to the village to stand for election as a "soldier’s branch secretary". He showed his specialty and led the village party branch to establish an e-commerce cooperative. Relying on the emerging formats such as "internet plus", e-commerce and live broadcast, he promoted the sales of agricultural products to the fast lane of "e-commerce economy" and promoted the collective income of the village.

  The quality of candidates determines the quality of the whole transition work. In order to select "good seeds", Shandong Province insists on putting political standards in the first place, so that outstanding talents who are willing, practical and successful have the opportunity to have a stage. The province has organized two rounds of analysis and judgment, and all localities have selected talents and appointed talents in the "deep water", implemented the "return plan" for outstanding talents in rural areas and the "progressive training plan" for reserve talents, and successively returned 36,000 talents abroad.

  Qianqiu inheritance, talent-oriented. Selecting excellent and strong cadres is an important task in this transition. All localities have broadened their channels, and selected talents and abilities in an eclectic way by "staying" among current village cadres, "picking" among rural youth with outstanding performance in major work, "choosing" among rich leaders and outstanding veterans, and "inviting" among migrant workers and university graduates.

  "Before the re-election, village cadres were generally older, with low academic qualifications and weak ability." The relevant person in charge of the Organization Department of Changzhou District Committee of Wuzhou City, Guangxi Province frankly stated that at the beginning of the change, the district paid attention to strictly selecting people from the source. Changzhou District dispatched 31 department-level cadres to lead the team, investigated and analyzed 45 villages in the district one by one, conducted heart-to-heart talks, and produced a "physical examination report" to check the political performance, performance of duties, honesty and self-discipline of 835 initial candidates. At the same time, through research, recommendation from the masses in party member, selection of government agencies and units, and external liaison and feedback, we will comprehensively broaden the channels for talent selection.

  "Did you see the candidates posted in the village? Which cadres are you impressed with? " "What do you think is good about this cadre?" With questions, the new working group went door to door to collect opinions and suggestions from the masses, weed out "sick seedlings" and pick out "good seedlings", and a group of capable and responsible people stood out. "By the masses to participate in the screening, let us really realize that the golden cup and the silver cup are not as good as the reputation of the people." Li Liusong, newly elected secretary of the Party branch and director of the village committee of Ludong Village, Daoshui Town, said.

  Choosing the best and matching the best is the goal, and strict control is the guarantee. Tangshan City, Hebei Province refined the negative list, set up a special class for joint qualification examination, introduced a joint qualification examination method, and checked all interested candidates at different levels. There were 30,130 pre-qualified candidates in county and township qualifications, and 1,389 unqualified candidates were cleared. Qilian County, Qinghai Province, through the village-level "entrance", the township "supervision" and the county-level "examination", the 150 members of the village party organizations to be recommended are comprehensively portrayed from five dimensions, such as qualifications, mass base and moral conduct, to prevent "recommendation with illness" and "election with illness".

  Focusing on rural revitalization, all localities have chosen the best among the good and the best among the strong "leading geese", and a large number of outstanding talents who are interested in rural revitalization have entered the village "two committees" team, which has injected momentum into the realization of high-quality rural development.

  The data shows that the overall optimization of the village team structure, especially the leaders’ team, has been achieved after the re-election: the academic qualifications have been significantly improved, with 74% of the members of the village "two committees" having a high school (technical secondary school) education or above, an increase of 16.7 percentage points, and 46.4% of the village party secretary having a college education or above, an increase of 19.9 percentage points. The proportion of capable people has increased, and 73.6% of the village party secretaries are experts in getting rich in their villages, people returning from work and business, college graduates, retired military personnel and other people with strong ability to get rich, an increase of 23.6 percentage points. Women members have increased, accounting for 28.1% of village teams, up by 7.1 percentage points, and each village team has at least one woman member. The age has generally declined, and the average age of the members of the village "two committees" is 42.5 years old, a decrease of 5.9 years; The average age of village party secretaries is 45.4 years old, down by 3.9 years, and 96.7% of villages have team members under the age of 35.

  When talents get together, careers flourish. The new team with high academic qualifications, full energy and vitality is showing a new atmosphere with hard work.

  Strict discipline and clear rules ensure that the general election is clean and upright.

  Wu Mingxia, member of the Party Committee of Dongwu Town, Yinzhou District, Ningbo City, Zhejiang Province, was deeply impressed by the first voter on the election day of Xiaobai Village Committee: "Before dawn, the 80-year-old Lin Rubao came to the ballot box and cast his sacred vote." The villagers are used to getting up early, and the day before the vote, the staff made full preparations to welcome the voters early.

  In order to ensure the smooth transition process, Dongwu Town has launched the "two calendars and five processes". "With the calendar and process, it is clear what to do every day and which steps to perform, and it is very convenient to operate." Dong Yingying, a cadre of the Party and Government Office in Dongwu Town, said.

  It is directly related to the success or failure of the re-election work to promote strictly according to the law and regulations and create a clean and tidy environment.
