On the afternoon of November 29th, the press conference of the State Council Joint Defense and Control Mechanism was held. National Health Commission responded to the recent incidents in which nucleic acid testing institutions were seriously dealt with because of fraud and other acts:

"For nucleic acid testing, we have always strictly controlled the access and quality of testing qualifications, constantly optimized technical specifications, and focused on strengthening the supervision of testing institutions, including third-party testing institutions. Since the beginning of this year, the health administrative departments in Beijing, Hefei, Anhui, Shijiazhuang, Hebei, Xuchang, Henan, Inner Mongolia and other places have found some illegal problems in the supervision of testing institutions, and all of them have been severely punished. Some illegal institutions and individuals have also been investigated for criminal responsibility.

In the next step, we will continue to strengthen supervision, and resolutely deal with serious violations of the law by issuing false test reports. "

In the past few days, nucleic acid detection has been caught in the whirlpool of public opinion, while Shenzhen nuclear gene is the whirlpool in the whirlpool.

01 Constant violations and "expansion"?

On November 25th, a notice from Lanzhou Health and Health Commission became the focus of public opinion.

According to the notification, at 1 o’clock on November 24, the staff of Lanzhou Nuclear Huaxi Laboratory mistakenly entered the list information of individuals with abnormal nucleic acid testing into the negative personnel information package and uploaded it to the work system, so that the health code of individual persons to be transported showed negative nucleic acid testing. Lanzhou Health and Health Commission said that Lanzhou Nuclear Huaxi Laboratory will be dealt with seriously.

49301669765405229

Enterprise investigation shows that this Lanzhou Nuclear Huaxi Laboratory (hereinafter referred to as "Lanzhou Huaxi") was established just over three months ago. Just over a year ago, Lanzhou Huaxi’s brother company, Jinan Huaxi Medical Inspection Co., Ltd. (hereinafter referred to as "Jinan Huaxi"), was notified by the Health and Health Commission of Xingtai City, Hebei Province for its nucleic acid detection fraud.

It has been observed that since 2020, laboratories related to nuclear Hua Xi have been punished many times.

99651669765405283

The parent company of these involved companies is Shenzhen Nuclear Gene Technology Co., Ltd. (hereinafter referred to as Shenzhen Nuclear Gene), and the founder is Zhang Nuclear. According to the industrial and commercial data, the actual controllers of more than 30 medical inspection laboratories under the Nuclear Gene are all Zhang Hezhen, and Zhang Shanshan is the supervisor of more than 10 of them.

Since 2022, 16 medical laboratories have been opened for nuclear genes, 8 of which were established in October.

According to "Nuclear Gene Group" WeChat official account, in 1990, Zhang He was admitted to China Medical University and became the first batch of DNA identification graduate students in China. After graduation, shenzhen public introduced high-tech talents to shenzhen public to organize the earliest DNA identification center in China. 

After leaving the Public Security Bureau, he started his own business and set up Shenzhen Hongshi Villa Decoration Company. In 2012, Shenzhen Nuclear Gene Technology Co., Ltd. was established. In 2013, Zhang Nuclear established Guangdong Huaxi Forensic Material Evidence Judicial Appraisal Institute, and established the first laboratory with the qualification of judicial appraisal license.

Zhang Hezhen once said: "There are many companies doing genetic testing now, but there are actually only two types of companies in the market today, 3% are reliable, 97% are unreliable, and I only do 3%."

02 The track is "overcrowded" and accounts receivable have increased substantially.

An epidemic situation made the subdivision track of nucleic acid detection instantly become a crowded "square", and the detection level became uneven under the crowd.

According to the incomplete statistics of People’s Daily Health Client, at least 10 nucleic acid detection institutions in 7 places have been put on file for investigation, notification or punishment this year, involving Beijing, Hefei, Anhui, Shijiazhuang, Hebei, Xuchang, Henan, Hohhot, Inner Mongolia, Kunming, Yunnan and Lanzhou, Gansu.

Since June this year, documents have been issued continuously at the national level to strengthen the supervision of nucleic acid detection and ensure the accuracy of test results. On June 2, the State Council Joint Prevention and Control Mechanism issued the Notice on Further Strengthening the Whole Chain Supervision of Nucleic Acid Testing in Covid-19, which will strictly manage the qualifications of testing institutions and personnel, standardize the management of sample collection, preservation and transshipment, strengthen the daily supervision and management of nucleic acid testing institutions, strengthen the supervision of nucleic acid testing institutions in emergency and other aspects, and directly revoke the Practice License of Medical Institutions by setting up a "traffic light" for the entry and exit mechanism of nucleic acid testing institutions.

On June 7th, National Medical Products Administration issued a notice to further strengthen the quality and safety supervision of detection reagent products in Covid-19 to ensure product quality and safety and effectively serve the overall situation of epidemic prevention and control.

The sudden "expansion" of the track stems from the attraction of huge demand.

Since 2020, as an important member to undertake the task of nucleic acid detection, the status of third-party medical testing institutions has greatly jumped, and the industry has undergone earth-shaking changes.

According to the statistics of orient securities, the market scale of nucleic acid detection in China will reach 13.2 billion yuan in 2021, with a year-on-year increase of +9.1%. According to the forecast of CBinsights, the market scale is expected to reach 14.6 billion yuan in 2022, showing a rapid growth trend. According to the data of enterprise investigation, there are 1702 enterprises related to medical testing in China, including about 145 new enterprises related to medical testing this year, and the investment of enterprises continues to increase.

Taking the head enterprise as an example, in the first three quarters of 2022, Dean Diagnostics realized revenue of 15.63 billion yuan, a year-on-year increase of 67.37%; The net profit of returning to the mother was 2.428 billion yuan, a year-on-year increase of 96.94%. The substantial increase in performance is mainly due to the growth of inspection business.

The data shows that the diagnostic service business grew rapidly, with revenue of 9.875 billion yuan, up 117% year-on-year, and revenue excluding COVID-19 business was 3.485 billion yuan, up 20% year-on-year. It can be seen that COVID-19’s business growth is obviously faster than that of regular business, which is an important driving factor for revenue growth.

Compared with 2019, the annual revenue of Dean Diagnostics was 8.453 billion yuan, and the net profit returned to the mother was 347 million yuan. After the epidemic "Black Swan" flew in, the figures on Dean’s report card of diagnostic profit have multiplied several times on the basis of a larger base.

Another leading enterprise, Jinyu Medicine, also achieved a large performance growth this year. In the first three quarters of 2022, the operating income of Jinyu Medical was 12.208 billion yuan, a year-on-year increase of 41.67%; The net profit of returning to the mother was 2.448 billion yuan, a year-on-year increase of 46.41%. The increasing demand for laboratory tests is also the main reason for the rapid growth of Jinyu medical business.

But behind the 10 billion revenue, the real data is not as optimistic as it seems.

Relevant performance reports show that as of the end of September this year, Dean’s diagnosed accounts receivable rose to 10.754 billion yuan, a year-on-year increase of 71.02%. The accounts receivable of Jinyu Medical also reached 7.433 billion yuan, accounting for 60% of the revenue in the same period.

From the perspective of accounts receivable accounting for total assets, in 2019, Dean diagnosed that accounts receivable accounted for 30.98% of total assets, and in the first half of 2022, accounts receivable accounted for 51.15% of total assets.

It has been observed that the sharp increase of accounts receivable widely exists in enterprises that operate COVID-19 detection related reagents and provide nucleic acid detection services.

Many enterprises responded that the status quo of accounts receivable basically matched the characteristics of business model and the growth of income scale. Because accounts receivable mainly came from medical institutions and the government, the risk of bad debts was low and the overall risk of bad debts was controllable. However, there are also media reports that some enterprises are under greater pressure to pay back the money, and a few small enterprises have greater cash flow risks.

In addition to the income from testing in COVID-19, the routine business of head enterprises has also achieved a certain degree of growth in the past two years. In the first half of 2022, the revenue from the diagnosis service business excluding COVID-19 business of Dean Diagnostics was 4.014 billion yuan, an increase of 31.97% compared with the same period of last year and 37.69% compared with the same period of 2019.

However, it is an obvious fact that the original conventional market for nucleic acid detection cannot bear such a large scale of business. When it returns to normal, the existing market scale will shrink sharply, and the huge production capacity and personnel blindly expanded due to the epidemic will be difficult to digest and absorb.

Once the lucrative scenery is unsustainable, how to "land" is the biggest problem facing these enterprises.

May 18th is "World Museum Day". In order to celebrate the festival of this global museum, Chongqing Natural Museum will open its treasures warehouse to the public for the first time free of charge. On that day, visitors can walk into the 340-square-meter warehouse and watch more than 1,200 precious specimens from all over the world at close range. Members of the public can pay attention to the reservation activities of WeChat WeChat official account in Chongqing Natural Museum.

On May 14th, with the approval of the Natural History Museum, the reporter went into the warehouse in advance to inquire about this special "animal world" for readers.

"Unlike fossil specimens, there are no ancient creatures in the treasure warehouse, but all living animals. Among them are not only giant pandas, golden monkeys, South China tigers, but also rare albino black bears in nature." Zhao Liwei, the collection manager of the collection management department of the Natural Museum, said that some of these specimens came from the old collections in the museum, some from the collection of specimens, and some from the donation of the Bellin Foundation.

Two panda specimens made their debut.

In the vast warehouse, more than 1,200 animal specimens are placed on a three-storey specimen rack in different categories. Some of them have been "living" in the warehouse for decades, and some have just "moved" into the warehouse.

Among them, the latest "check in" are two giant panda specimens. These two giant panda specimens have just been restored by a professional restoration team. Before they were made into specimens, they were the old panda skin specimens in the museum.

Is it difficult to "stand up" the panda skin specimen?

Zhao Liwei said that there is a very difficult link in specimen restoration, that is, to present the specimen with the most natural posture of the animal before its death.

"In order to restore these two giant panda specimens, the restoration experts not only watched various videos of giant pandas repeatedly, but also made a special trip to the zoo to record the movements and expressions of giant pandas at close range." Zhao Liwei said that unlike the giant panda cultural and creative products, the specimen restoration will never adopt the posture that people like but the giant panda itself can’t make. "That is to say, their restored posture is a common state of giant pandas in nature."

So, what is the giant panda that was finally restored? A prone on the rocks, side face spit out the pink small tongue; The other one sat on the ground and gave a grin with his head tilted.

As the oldest natural museum in southwest China, there are several giant panda specimens in the treasures warehouse of Chongqing Natural Museum, which are prone or standing, showing different postures.

Rare albino black bear specimens are hiding in it.

In addition to all kinds of giant panda specimens, there is also an albino black bear specimen in the treasure room, which is also the old collection of Chongqing Natural Museum.

In order to let the audience appreciate this specimen better in the coming open day of the warehouse, the collection manager gave it a "black and white match"-a black bear specimen was placed next to the albino black bear.

Zhao Liwei said that in nature, the phenomenon of albinism of black bears is relatively rare, and albino black bears that can be made into specimens are even rarer.

What exactly is the albino black bear specimen like?

From a distance, it looks like a miniature polar bear. Its front left palm is slightly raised, and its whole body leans forward slightly, as if it is slowly moving forward.

At present, the recorded cases of albino bears are very rare. In 1950s, local residents in Shennongjia, Hubei Province hunted an albino bear. This albino bear in Shennongjia was identified as an albino species of Asian black bear, which was also the earliest case of albino bear found in modern China. In 2000, there were also traces of albino black bears in Shennongjia.

It is understood that albinism exists widely in all kinds of vertebrates, but it is rare. Usually, melanin cannot be synthesized normally in animals due to gene mutation, which makes it appear white, yellow-white or light yellow in external form.

See more head and shoulder specimens donated by the Behring Foundation.

In addition to all kinds of animal specimens placed on the specimen rack, there is a special wall with dozens of head and shoulder specimens hanging on it in the treasure warehouse.

Most of these head and shoulder specimens belong to Cervidae, and they were donated to the Natural Museum by the Bellin Foundation in batches.

Visitors who have been to the Natural History Museum know that there is a Belling Hall on the first floor of the museum.

Since April 2011, kenneth e behring, a world-famous philanthropist, the founder and chairman of the Global Health and Education Foundation and an honorary citizen of Chongqing, has visited Chongqing seven times in succession.

During this period, the old man donated 325 wild animal specimens worth more than $30 million to Chongqing Natural Museum, which together formed the Bellin Hall-Animal Planet Exhibition in the museum. The audience can see nearly 300 rare wild animal specimens here. They are various and lifelike, which can be called a trip to the global animal carnival.

But this is not all the specimens donated by Bellin, because the exhibition hall area is limited, and some duplicate specimens are collected in the treasure warehouse, which also means that the audience can see more wild animal specimens donated by Bellin in the warehouse.

The 2024 League of Legends Global Finals knockout is about to start, and all LPL members will meet in Paris.

The 2024 League of Legends Global Finals knockout is about to start, and all LPL members will meet in Paris.

2024-10-17 17:51:21.0 Source: Northland. com

With the end of the Swiss round of the League of Legends Global Finals in 2024, the No.1 seed BLG Xingji Meizu, No.2 seed TES Team, No.3 seed Suzhou LNG No.9 Electric and No.4 seed WBG TapTap in LPL Division have all advanced to the knockout stage and successfully joined Paris. The knockout round will officially start at the Adidas Stadium in Paris, France at 20:00 on October 17th, Beijing time, and the eight teams from Switzerland will face greater challenges!

man of valorfear nothing,LPL gathers in Paris

In the previous Swiss Round, 16 teams from different divisions competed fiercely, and finally eight teams broke through. They are four teams in ——LPL, BLG, TES, LNG and WBG, HLE, GEN and T1 in LCK, and FLY in LCS, and they will jointly compete for the semi-finals in 2024! It is worth mentioning that the LPL division once again achieved full promotion and jointly fought in the knockout stage!

According to the lottery results of the knockout stage, HLE, the first seed of LNG, WBG, BLG and LCK, gathered in the upper half, while the lower half was composed of TES, T1, GEN and FLY. Eight teams will launch a new round of fighting in their respective halves, and the final winners in the upper and lower halves will travel from Paris to London to compete for the final championship trophy!

Strong man versus strong man,onestrugglesuperiority or inferiority

On October 17, the first battle of the knockout will usher in a "LPL civil war", LNG against WBG. The two teams have played several times in the league this year, and they have won and lost each other. This time, the battle will be more intense. In addition to the stable performance of Scout and GALA, LNG’s excellent tactics, strategies and operations also demonstrated the team’s extraordinary strength, which also made them the first team in the Swiss round to advance 3-0. In contrast, WBG’s road to promotion is bumpy, but many experienced players in the team can always bring surprises at critical moments, especially Breathe, who brought five MVP performances, and Tarzan, a wild player from Morgana, who made his debut in this competition under the lock of "life and death". It is expected who will win the first round of the quarter-finals.

On the second day, it was a strong confrontation between the top seeds in the two major divisions, BLG against HLE team. As the last team in LPL Division to advance to the quarter-finals, BLG’s Swiss round competition was not smooth sailing, but in the final match against the No.1 seed G2 team in LEC Division, the summoners also saw the competitive strength of BLG after the state callback. In this match between BLG and HLE, the summoners are most looking forward to the duel between Elk and Viper, both of whom are very comprehensive players, and both of them have played the role of winning the game in previous competitions. At the same time, it will be the first time that HLE has faced the LPL team in this global finals. What is the result, and whether BLG can win the key game, let us wait and see!

The competition on October 19th is also a duel between LPL and LCK. TES will face the T1 team, the champion of last year’s global finals. The two sides met in the previous Swiss round Bo1, when TES won with better team fighting strength. TES performed well in the Swiss round, and Creme, a middle-road player who entered the stage of the global finals for the first time, dared to fight and became the player who scored the highest average injury in the Swiss round. But on the other side, it is the legendary player Faker who holds the "four crowns" in the global finals. His clear game ideas and team battle handling will bring great challenges to TES. The two teams, who are more and more brave, meet again. I believe they will bring a wonderful confrontation to the summoners, and I also look forward to TES’ hard work and further success!

On the fourth day, FLY, the only fire in LCS Division, will face GEN, a strong team in LCK Division. FLY finally defeated the TL team in the same division in the Swiss Round and successfully got the last quarter-finals ticket. They left a deep impression on the summoners with their unique heroic choices in the Swiss Round, and the play of veteran Bwipo may be the key to FLY’s victory. GEN continued their consistent and stable performance in the Swiss round, and the "middle field combination" of Chovy and Canyon always led the team to control the rhythm of the game and break the opponent’s defense line one by one. What kind of confrontation will the two teams bring? Don’t miss it.

Watch the 2024 League of Legends Global Finals. You can watch the whole event through League of Legends client, Pocket League of Legends and League of Legends events, LPL.QQ.COM in official website, Huya Live, DouYu, BILIBILI Live, Migu Video, Tencent Video, Tencent Sports, Sina Weibo, WeChat Video and bestv.

In addition, the 2024 League of Legends Global Finals cinema viewing has also been officially opened. Now, search the movie competition alliance applet to get the billing information of your nearby viewing point, and cheer loudly offline together!

Fight without regret and move forward side by side. I believe that all four LPL teams will meet the upcoming challenges in the best condition. At 20 o’clock on October 17 th, Beijing time, the elimination of the 2024 League of Legends Global Finals officially started! The world focuses, seeing is believing, and we witness it together!

Disassembly of Xiaomi USB charger 60W fast charging version: practicality is greatly increased.

As early as the summer of 2016, Qingmi under the Xiaomi ecological chain launched a subversive concept of "Qingmi Charging Station" multi-port charger, which has five QC2.0 output ports that can be inserted at will.

    After experiencing several rare natural disasters in history and the test of the world economic recession caused by the American financial crisis, what kind of overall evaluation should be given to China’s national economy in 2008?


    How to evaluate the overall economic performance throughout the year?


    Ma Jiantang, director of the National Bureau of Statistics, who made his debut at the press conference of the State Council Information Office, was considerate, bringing not only detailed statistical data, but also his overall evaluation of the national economy in 2008: rapid growth, price stabilization, structural optimization and improvement of people’s livelihood.


    At first glance, it is growing rapidly. According to preliminary accounting, GDP in 2008 increased by 9% over the previous year. Although vertically, it is 4 percentage points lower than the growth rate of 13% in 2007, compared with other countries in the world, the growth rate of 9% is still a relatively high speed. According to the latest estimate of the International Monetary Fund, the average growth rate of the world economy in 2008 was 3.7%. According to Ma Jiantang, it has been calculated that in 2008, China’s economy maintained a growth rate of 9% in spite of difficulties, and its contribution to world economic growth exceeded 20%.


    Second, look at the price stabilization. In February, the price rise reached a peak, and the CPI rose by 8.7% that month. China government has taken a series of measures to increase supply, regulate demand, invigorate circulation and increase subsidies for low-and middle-income people. With these measures in place, it took about half a year to control the inflation rate from 8.7% to less than 5%, and it dropped to 1.2% in December.


    Third, look at structural optimization. While the national economy has achieved rapid growth, the primary industry, especially agriculture, has developed well. In 2008, China’s total grain output and unit yield both reached the highest level in history, with grain reaching 1,057 billion Jin. "In such a difficult time, a bumper harvest of grain can be achieved, which further proves that Chinese can support itself, which is also the greatest contribution to the world." As a doctor of economics, Ma Jiantang still remembers the debate about "Who will feed China" provoked by some foreign economists a few years ago. In addition to the industrial structure, the regional structure is also being optimized. Last year, the investment and industrial growth rates in the central and western regions were faster than those in the east.


    In 2008, energy conservation and emission reduction also made positive progress. From the perspective of energy consumption per 10,000 yuan GDP, it decreased by 4.21% in 2008. In the first three quarters of last year, sulfur dioxide emissions decreased by 4.2% and chemical oxygen demand emissions decreased by 2.7%. All these data indicate that China’s economy has made positive progress in building a resource-saving and environment-friendly society while overcoming difficulties and growing steadily.


    Fourth, see the improvement of people’s livelihood. In 2008, the annual per capita disposable income of urban residents increased by 14.5%, with an actual increase of 8.4%; The per capita net income of rural residents increased by 15% in nominal terms and 8% in real terms. It is not easy to maintain such growth under such severe economic conditions. At the same time, social security is increasing. In 2008, the total income of five insurance funds, including basic pension, basic medical care, unemployment, work injury and maternity insurance, was 1,380.8 billion yuan, an increase of 27.7%. The basic pension level and the minimum wage level of enterprise retirees all over the country are improving.


Main economic data:  


    China’s GDP in 2008 was 30.067 trillion yuan, an increase of 9%.


    In the fourth quarter of 2008, China’s economy grew by 6.8% year on year.

    Statistics Bureau: In 2008, the M2 balance of China increased by 17.8% compared with the end of last year.


    In the first November of 2008, the profits of 31 industrial sectors in China increased year-on-year.


    In 2008, the national economy as a whole maintained steady and rapid development.


    In 2008, the added value of industrial enterprises above designated size increased by 12.9% over the previous year.

    Answer a reporter’s question:


    Director of Statistics Bureau: The "consumption fever" will continue after the New Year.


    Ma Jiantang, Director of Statistics Bureau: The expected target of consumer price in 2009 is 4%.


    Chief economist of statistics bureau: the economy can get out of the downside in the second half of the year


    Ma Jiantang said that China’s GDP has jumped to the third place in the world: this is an objective trend.


    The National Bureau of Statistics is studying the establishment of a GDP growth ratio system.


    Director of Statistics: The economic data in December began to show positive changes.


    Director of Statistics Bureau: The final verification data of GDP in 2007 is scientific and accurate.

Roewe leads the future, and’ zero-burning guarantee’ reshapes the peak standard of new energy vehicles!

On July 4th, SAIC Roewe grandly released the Super Anxin Commitment, which ensured the safety of the battery and zero burning risk, and promised to complete the payment within 20 working days, setting a new benchmark for the whole industry. In addition, the brand has also launched a lifetime warranty policy of Sandian, regardless of whether the owner is the first owner or not, and it is not limited by the annual mileage. This policy applies to non-operating owners of many popular new energy vehicles under the Roewe brand, such as Roewe D5DMH, Roewe D7 EV, Roewe D7 DMH and Roewe iMAX8 EV. It is worth mentioning that both new and old car owners can enjoy this policy. This move is another powerful proof of Roewe brand’s technical strength and product quality after SAIC Magic Cube battery won the second prize of National Science and Technology Progress Award.

In today’s increasingly prosperous new energy vehicle market, Roewe not only stands on the forefront, but also takes users as the center and constantly innovates its service concept. Faced with concerns about the safety hazards of new energy vehicles, Roewe chose to "add" and launched the "Super Anxin Commitment" rights policy to create a comprehensive safety guarantee system for consumers.

Roewe knows that safety is the cornerstone of the development of new energy vehicles. Therefore, while improving battery safety technology, Roewe pays more attention to providing consumers with a comprehensive peace of mind experience. The "Super Anxin Commitment" rights policy launched this time not only covers battery safety, vehicle safety and other aspects, but also provides more intimate and convenient services for the actual needs of users.

This move of Roewe has undoubtedly set a new benchmark for the new energy automobile industry. It not only shows Roewe’s sense of social responsibility and responsibility as a car company, but also highlights Roewe’s core values of taking users as the center. I believe that under the guidance of Roewe, the new energy automobile industry will usher in a safer, more reliable and more convenient future.

Roewe Automobile announced its innovative "zero-combustion guarantee" policy, and promised that if the high-voltage battery pack of the vehicle spontaneously ignites, it will replace the owner with the same new car or a new car with the same value within 20 days, which shows its confidence in product quality. At the same time, Roewe also launched the "Three Power Lifetime Warranty" service, covering high-voltage batteries, drive motors and other core components, breaking the industry convention and providing mileage-free warranty for non-operating new energy owners. In addition, the newly launched "Super Anxin Service" rights and interests policy is also open to old car owners, ensuring that all car owners can enjoy fully upgraded after-sales protection, highlighting Roewe’s emphasis on user safety and satisfaction, and effectively enhancing the brand image and the preservation rate of new energy vehicles.

Roewe, as a member of China’s leading independent brand "National Team", dares to take the lead in launching the "Super Anxin Commitment" rights and interests policy by virtue of its excellent technical and quality strength, demonstrating its unparalleled self-confidence. Over the years, SAIC has continuously increased its investment in R&D, with a cumulative investment of 150 billion yuan, more than 26,000 technical patents and seven technical cornerstones. In the latest National Science and Technology Progress Award, SAIC Rubik’s Cube battery won the second prize for its innovative "zero heat out of control" safety protection system and excellent performance, which once again proved SAIC’s technical strength.

Roewe D7 EV, iMAX8 EV and other models are equipped with SAIC Rubik’s Cube batteries, providing users with all-round super security. At the same time, Roewe’s DMH super hybrid technology, with its industry-first powertrain brain PICU, realizes efficient power integration and control, greatly reduces the network load and data delay in the car and improves the operation speed. In the "China Heart" 2023 annual selection, Roewe D7 DMH super hybrid system won the honor of top ten engines and hybrid systems, which fully proved its excellent performance.

Roewe’s quality and strength are equally remarkable. In the hybrid vehicle extreme challenge, Roewe D5DMH showed great strength and won the championship of compact SUV group. In the "Extremely Hot Marathon" event, Roewe D7 DMH set a record of 2160km.

In the face of fierce market competition, Roewe actively practices the responsibility of its own brand "national team" and wins the market with technology, quality, price and conscience. Through the action of "Rongjuanfeng", Roewe meets the needs of consumers with high-quality and high-value products and promotes the popularization of quality. Now, Roewe has once again launched the "Super Anxin Commitment" rights policy to provide users with all-round security and worry-free car experience. This powerful move fully demonstrates Roewe’s service concept of "having confidence and daring to promise".

Reagan once joked that "I decided to declare war on the Soviet Union" caused panic.

    The U.S. government played an important role in the disintegration of the Soviet Union. According to peter schwartz, the author of "Victory-the Secret Strategy of the American Government to the Soviet Union" and a former employee of the US Central Intelligence Agency, the Reagan administration of the United States planned to bring down the state system of the Soviet Union as early as the 1980s. Due to the incompetence of the upper echelons of the Soviet Union, including the national security agencies, the premeditated plan of the United States was successful.


  Four dignitaries with ulterior motives tried to change the Soviet system.


    The Russian Independent published an article by Schwartz in 1996. According to Schwartz’s materials, this action in the United States began in the spring of 1981 and lasted until the end of 1986, a total of a little more than five years. This action was carried out behind the back of the public, the government and the Congress. Because this plan "goes beyond the scope of the current policy". The planning of this plan comes from a few senior American officials-US President Ronald Reagan, Director of the Central Intelligence Agency (CIA) william casey, National Security Adviser Richard allen, and Secretary of Defense Caspar Weinberg.


  


  William casey


    Schwartz’s book was written in conversation with activists involved in formulating strategic details at that time, which is also the value of this book. Please listen to what the relevant personnel said when proposing and deciding the task at that time: "Kathy, Allen and Weinberg, with the support of the President, decided to challenge the Soviet Union … We think the Yalta meeting is invalid."


    Richard Pappus, a historian at Harvard University, drafted Reagan’s latest American strategy against the Soviet Union, code-named NSDD-75. This strategy shows a "revolutionary turning point" in American policy. "The strategy clearly states that our current goal is not to coexist with the Soviet Union, but to change the system of the Soviet Union. The strategy confirms that we are fully capable of changing the Soviet system with external pressure. "


    The four men put forward the goal and began to seek the means to achieve it.


  CIA: Give communist party people a hard time.


    The way to destroy the Soviet Union was simple, although it was illegal according to the standards of the United States at that time: "It is the purpose of the United States to shake the Soviet system by taking advantage of the weaknesses within the Soviet Union." To this end, the United States launched a special action to involve the Soviet Union in two acute crises-the Polish crisis and the Afghan war by giving material and political support to the resistance forces.


    William casey, director of the Central Intelligence Agency, said in a meeting with the leadership of the Central Intelligence Agency: "Let’s give communist party people a hard look. We want them to bleed. Their officers’ sons will be sent home in zinc coffins. It’s these people we’re aiming at-it’s a trick. "


    The direct task of the United States is not to defeat the Soviet Union militarily, but to "make Moscow surrender for fear that the war will be transferred to Soviet territory". This is the reality. It is not difficult to find that what they want to shake directly is not the Soviet system or the Soviet society. The goal of the United States is to shake the will of those in power and their protectors; The focus of the attack is the core institutions that analyze intelligence and decision-making, as well as the behavior of the enemy. Kathy guessed right, this is the weakness of the Soviet Union.


  Reagan’s joke: I decided to declare war on the Soviet Union.


  


    The new president of the United States launched a psychological pressure movement in the first few months of his re-election. Code name: "Reagan-the awesome cowboy". "The purpose of the movement is to influence the Kremlin’s thinking and make them concentrate on military defense … From a strategic point of view, the image of the cowboy is very suitable." For the Soviet Politburo, Reagan played the role of a geopolitical hooligan. The old actor played this easy role brilliantly: the bad boy in the East was threatened and turned his cannon around, while the good boy secretly put the lit cigarette under the fire hydrant. As a result, the water sprayed from the ceiling, and the cannon became a drowned rat, and it couldn’t sound …


    Reagan made an unforgettable joke on live TV: "Gentlemen, I have decided to declare war on the Soviet Union … The nuclear attack will begin in three minutes".


    Reagan’s joke on TV really shocked the Politburo of the Soviet Union, so that the best Soviet reconnaissance agency in the world turned to collect information about what seemed to be an inevitable Armageddon. When the scouts fumbled for the signs of "America’s first nuclear strike", "the CIA and the Pentagon threw out a false secret plan, the purpose of which was to bring down the Soviet economy. In short, we caused great confusion to the Soviet Union. "


  American economic attack on the Soviet Union


    Reagan was not interested in whether the Soviet Union had vitality objectively. His goal was to reduce this vitality to zero.


    On the day of Brezhnev’s death, the anti-Soviet economic war began. The instruction code is: NSDD-66. Henry Ron, Reagan’s Soviet economic adviser, said: "We should have high-level military equipment that makes Moscow want to catch up with us. At the same time, we stop supplying them with the materials necessary for their survival, and we will see how the Soviet system collapses in these 10 years. "


    The United States made an analysis of the price paid by the Soviet Union for its own purposes. Price, in its original meaning, is hard currency. For the Soviet Union, oil and natural gas are the main sources of income dollars. So the following tasks were put forward:


    Weaken the Soviet Union’s ability to sell energy carriers at high prices.


    Weaken the Soviet Union’s ability to buy or steal western technology.


    Reagan’s men made great efforts to cut off the two sources of foreign exchange in the Soviet Union, cut off the designed oil pipeline and lower the oil price. They persuaded Saudi Arabia to lift the restrictions on oil exploitation by the Organization of Petroleum Exporting Countries. In 1985, their efforts brought decisive results: Saudi Arabia put oil beyond the previous quota on the market, the price dropped by half, and the Soviet Union lost all its money.


  The Kremlin paid a heavy price.


    Schwartz expounded the policy of the United States in reform as follows: "After 1985, the United States not only wanted to annoy the Soviet Union, but also wanted to win and move the war in Afghanistan to the Soviet Union." However, in the usual fatalistic sense, this is not a "conspiracy" because it is well known in Moscow. The book says, "They have their own intelligence personnel. When planning the operation, we bet that Moscow can guess what we are doing. Moscow was angry and threatened, but it did not reach the step of changing its policy. "


    An expert and one of the KGB leaders, General Fedot Bobkov, confirmed this. "Do we know all these things? Of course I know. In fact, the leaders of the Soviet national security organs, the party and the government all know the atomic attack plan. Know the plans of American intelligence agencies and other secret services aimed at overthrowing the Soviet system. "


    The KGB knows everything, but, concluded Zwaz, "The KGB doesn’t know what all this means."


    Schwartz pointed out: "The war cost the Kremlin 4 billion dollars and thousands of young lives every year." This kind of confusion in human technology has caused injuries and disabilities. Today, Eurasia is in turmoil, which shows that Kathy’s whole set of practices are still working, killing each other and fighting each other.

One-week early warning of typical electric fraud cases

October 19th, 2024-October 25th, 2024

Online brushing fraud

On October 22, 2024, citizen Liu reported to the police that he saw an advertisement for doing a part-time job on the Internet. After scanning the code into the group, the customer service asked him to click the link to download the "Dongheng" APP. After logging in, I did the task under the guidance of customer service, and I tried to make two orders and got a rebate. After that, the investment amount was increased by a total of 50,000 yuan. After that, the other party filled in the bank card incorrectly, which led to the freezing of the account, and it was necessary to unfreeze the account by offline cash withdrawal. If the letter is true, he will withdraw 40,000 yuan from the bank and transport it to the designated location through the network car. After losing contact with the other party, I called the police.

Lanzhou Anti-Fraud Center reminds: The masses must be vigilant, and don’t believe in the rhetoric of online rebate and online investment to make money. If you ask to use express delivery or online car to send cash or gold, immediately refuse and call 110 to report.

Poverty alleviation fraud

On October 21, 2024, Xie Mou, a resident of our city, reported to the police that he had received an email from Yunda Express, which contained a notice of "distributing poverty relief funds". Click on the link "58d.buzz" on the file to enter the webpage of "Helping the People in China". After registering and logging in, contact the customer service of the platform. The other party induced him to transfer 91,000 yuan to the designated account on the grounds that he needed to pay a handling fee for applying for poverty alleviation funds. After discovering that he was cheated, he called the police.

Lanzhou Anti-Fraud Center Tip: Don’t believe it when you receive an unknown courier or email, let alone scan or click on the QR code or link on the courier. When you receive such "policy documents", you must call the relevant departments for verification. Do not blindly operate the transfer. If you receive similar emails, please call 110 or 96110 in time.

Million-guarantee fraud

On October 19th, 2024, the citizen He Mou reported to the police that he received a strange phone call, and the other party claimed to be the customer service of Alipay Maintenance Center, claiming that he had opened the "Million Guarantees" service, and the free use had expired. If he continued to use it, he would have to charge 800 yuan every month. Do you want to close the service? He agreed to close because he was worried about being deducted. After that, the other party asked him to click on the link and enter information such as ID card, bank card and verification code on the grounds that "one million guarantee" needed "authentication", and 69,000 yuan in his bank card was transferred away, so he called the police.

Lanzhou Anti-Fraud Center Tip: WeChat and Alipay Million Guarantees are opened for free by default, without paying any fees. Anyone who asks for transfer or provides personal information on the grounds of closing the million guarantee is fraud!
