　　Peng Jihe is taking care of his injured son.

　　

　　　　Rescue the scene

　　

　　　　The injured couple

　　

　　Zhang Shuiwang, who was slightly injured.

　　-The Futian section of Pingxiang of Shanghai-Kunming Expressway had a car accident yesterday.

　　-Eight people were killed and 18 injured.

　　News tip: At about 0: 15 yesterday, a serial car accident occurred at the 506 public pile of Futian section of Pingxiang of Shanghai-Kunming Expressway. After a sleeper bus rolled over to avoid the truck, it was hit by a big truck. Three people died on the spot, five died after being rescued by the hospital, and 18 passengers were injured to varying degrees.

　　The passenger car avoided the sudden rollover of the truck.

　　When the reporter rushed to the expressway, the scene was still being cleaned up. High-speed traffic police and Pingxiang public security, fire protection, 120 and other departments are rescuing the wounded. The reporter understands that the cause of the accident was a Zhejiang C08980 sleeper bus from Hunan to Zhejiang, which was caused by avoiding the rollover of a truck in front. A driver on the sleeper car said: "When the incident happened, the car was driving on the highway, and suddenly a truck in front stepped on the brakes, and our driver also stepped on the brakes quickly." At this time, the bus rolled over, and a 2-year-old boy in the car died on the spot in the rollover. "

　　Zhang Shuiwang, the lightest injured passenger, told reporters that at 2 pm on December 12, he and several fellow villagers got on the bus from their hometown of Longche Township, Longshan County, Hunan Province, and prepared to return to Wenzhou, Zhejiang Province. At that time, the sleeper bus in which they were sitting suddenly rolled over. At that time, the passengers in the whole bus were still asleep. When he woke up, the first thing he heard was screaming and crying.

　　The boy was knocked out of the window when he urinated.

　　Passenger Peng Jihe, 31 years old, has been working in Wenzhou with his wife for many years. On December 12th, Peng Jihe deliberately went home to bring his son Peng Zhengquan back to Wenzhou for the New Year. In this car accident, Peng Jihe was injured in many places. His son Peng Zhengquan was sent to the intensive care unit because of a broken head and a broken right foot.

　　According to Peng Jihe, before the incident, he and his 3-year-old son Peng Zhengquan sat in the first row of the sleeper. He woke up because his son had to pee. With the rapid braking sound, the sleeper car he was riding suddenly rolled over. Later, he found that his son was gone. When he saw the broken window and the glass all over the floor, he immediately thought that his son had been knocked out of the car.

　　Later, he endured the pain to see his son. He first found a boy with blood all over his head lying on the ground not far from the bus. At this time, he quickly confirmed from other passengers that the boy was dead. Just as he was about to pick up the boy, he soon found that a few meters in front of the bus, his son was crying for his father.

　　The rollover bus was hit by the truck behind it again.

　　At noon on the 13th, in the north branch of Pingxiang People’s Hospital, the reporter saw some passengers injured in the accident. The injured Zhang Shuiwang said: "When the accident happened, we were all sleeping. Our position at that time was close to the rear of the carriage. After the car rolled over, the glass in the rear trunk was all broken, and it was dark outside. I saw an exit and climbed out of the carriage. " Chen Desheng, a fellow villager of Zhang Shuiwang, told reporters that another terrible thing happened after they climbed out for more than ten minutes. A truck couldn’t dodge, and suddenly rolled over and hit the bus.

　　The reporter learned from the relevant departments that after the bus rolled over for more than ten minutes, the surrounding light was not good. A truck of Fujian F50575 hit the back of the bus and turned to the ground, and the truck driver died on the spot. Passengers sitting on the edge of the sleeper waiting for rescue were injured by trucks, and many people were killed or injured.

　　Husband and wife cheat their families in good faith after being injured

　　According to reports, after the first car accident, many passengers who woke up from their dreams were launching self-help and rescue, but they were knocked down by the big trucks coming from behind. Passengers Zheng Peanut and Li Demei were injured while saving people. For fear of affecting their son’s study in high school, the couple climbed out of the car, held back the pain and called their family, and lied in good faith that they had something urgent in Pingxiang and might travel home for a few days after finishing their work in Pingxiang.

　　The cause of the accident is still under investigation.

　　The reporter learned from the relevant departments of Pingxiang City that after the incident, many departments in Pingxiang City quickly rescued them. Eight people were killed and 18 passengers were injured in the serial car accident. At present, the injured passengers have been sent to the hospital for treatment, and their emotions are stable. On the morning of December 13th, leaders of Pingxiang Municipal Committee visited the injured in the hospital and asked relevant departments to properly handle the aftermath. It is also known that at 8 am yesterday, the Futian section of Pingxiang of Shanghai-Kunming Expressway resumed traffic, and the cause of the accident is still under investigation.

　　【PConline talk】 Since the popularity of smart phones, their endurance performance has become the main factor for everyone’s criticism. Although the current mobile phone has a large battery of three or four thousand mAh, it still cannot escape the situation of heavy users rushing every two days or even every day. At present, limited by the development of electrode materials/structures, the energy density of lithium batteries cannot be increased indefinitely. Therefore, charging has become an essential part of our daily life. So what is the knowledge of charging mobile phones? Today, the author talks to you about "how to charge correctly and safely."

Brief introduction of charging principle of mobile phone lithium battery

　　Charge first①In the constant current stage, the actual battery voltage is lower than the charging voltage (mostly 4.3v), and the battery voltage rises during the constant current charging process. When it rises to about 4.3v (the battery charge is about 85%), it enters.②Constant voltage mode, charging current gradually decreases, charging is about to be completed, and then enter.③Trickle charging mode, charging with pulse current, extending battery life.

　　Let’s start with a charging process diagram of mobile phone charging (lithium battery):

Battery charging curve

　　It doesn’t matter if you don’t understand the above one. In fact, in simple terms,The whole charging process of smart phone can be divided into three parts.：

　　①Constant current stage, when the actual battery voltage is lower than the charging voltage. The battery voltage (red solid line in the figure) gradually rises from a low value to a fixed value, but the current (blue solid line in the figure) remains unchanged. This is the constant current process of lithium battery charging.

　　②In the constant voltage stage, after the battery voltage reaches a fixed value, the current output to the battery gradually decreases, and the charging efficiency also begins to decrease. And this process is a constant pressure process.

　　③Trickle charging mode, finally, when it is close to full, enter the trickle charging mode and charge with pulse current until it is completely full, and the battery charging is completed.

Have you tried all these wrong charging methods?

　　1. Buy a new machine and charge it for 12 hours to "activate" the battery.

　　Many friends around me like to charge their new mobile phones for 12 hours, saying that this will activate the battery. In fact, the activation of lithium battery is not so troublesome. After long-term storage, lithium battery will indeed enter a "dormant" state, and its capacity is lower than normal. At this time, it only needs to be charged normally for 3~5 times (without deliberately charging/discharging) to activate the lithium battery and restore it to its normal capacity.

　　So you don’t need to drain the battery and charge it continuously for 12 hours when you buy a new machine.

　　2. Plug in the charger and play with your mobile phone while charging.

　　We often hear in the news that someone’s mobile phone explodes or gets an electric shock while charging. The final investigation results show that most of them are caused by shanzhai chargers, so if you need to buy a non-original charger, you must buy a product that has passed the national 3C certification, and the input/output parameters are correct, and the manufacturer information is available.

　　Simply put, when choosing a charger, you need to pay special attention to the following situations:

— — （1）.The input voltage is preferably a broadband voltage, that is, 100~220v/50~60Hz.In some areas, the charging head only has 110v input. If you take it back to China, you can burn the charger directly, or burn the mobile phone!

— —（2）.The output voltage is about 5v (4.9/5.1), and the larger the output current, the better (if it is too small, the charger often heats up at full load and the output is unstable), but if one end of the wire is a microUSB port, it will basically not exceed 3a, and the Type-C port may have more than 3 A.The amperage here only represents the allowable output current, not the real output current.

— —（3）.National 3C certification is a must.

— —（4）.Manufacturer information must be available.

— —（5）.The work of the cottage charger is rough (especially the beard insertion and the sealing edge of the shell) and the font is fuzzy, which must be distinguished.

— —（6）.Mobile phones that support fast charging are not recommended to use too thin wires for charging. VOOC flash charging can only use original wires, and QC fast charging wires must ensure the integrity of D+/D- lines (that is, connecting computers can identify devices).

　　In addition, we should not play while charging. After all, when charging, the battery and charging related circuits will emit a lot of heat. If the Soc of the mobile phone runs at high load, the body temperature will be too high. The mobile phone with too high temperature will also control the heat by reducing the performance and charging speed, which will lead to the slow charging experience.

　　3. Charge only when there is no electricity, and it will be full as soon as it is charged.

　　Don’t wait until the battery of your mobile phone is completely exhausted, and there is no need to fully charge the battery every time.Most of the current mobile phones are lithium batteries, and the emphasis is on "eating less and eating more meals". The life of lithium battery is measured by the charging cycle, not the charging times as everyone thinks. The charging cycle refers to the process that all the battery charges from full to empty, and then from empty to full. If there is a 2000 mA battery, you will be fully charged after every 200 mA, then you have to charge it 10 times to calculate a charging cycle (2000 mA =200mAh times 10 times).

　　The lithium battery that the mobile phone is now equipped with has no so-called memory effect. There is no need to worry about the impact of insufficient charging on battery life.Fill it if you want, and pull it out if you want.

　　4. When charging, the fever is obvious. Still wearing a mobile phone case.

　　Nowadays, almost everyone on a smart phone will give him a gorgeous "coat". I don’t know that lithium batteries will be hot when charging. These gorgeous "coats" will hinder the heat dissipation when charging the mobile phone, thus affecting the charging speed and even accidents.

　　If the user finds that his mobile phone is not obviously hot when charging, there is no need to take off the mobile phone case. If the mobile phone is hot when charging, he will take it off decisively.

Tip: How to charge quickly?

　　1. Shutdown charging/flight mode charging

　　　Many people know that the screen and processor are the most power-consuming places of mobile phones, but in fact, the RF module of mobile phones also consumes a lot of power, that is, even if you turn off the screen, if the mobile phone is still synchronizing data (for example, WeChat is still receiving messages), then your charging speed will not be fast.

　　So, when needed,urgentWhen charging, turning off the power of the mobile phone is the fastest charging method. In addition, we can also switch the mobile phone to flight mode, cut off the synchronization of data and improve the charging efficiency.

　　2. Make the phone cooler

　　In addition, too high/too low temperature will also affect the charging efficiency of lithium batteries. Apple said that the iPhone has the highest charging efficiency at room temperature of 22℃.

　　Android phones also use lithium-ion batteries or lithium-ion polymer batteries, so the appropriate charging room temperature should be close to iPhone. Therefore, avoiding too high or too low temperature during charging is also a way to improve the charging efficiency of mobile phones.

　　3. Avoid using computer USB port to charge.

　　When choosing a charger, many people will plug their mobile phones into the USB port of the computer conveniently, but the current output from the USB port of the computer is usually less than 1a(USB 2.0 500mA, 3.0 900mA). Therefore, it is recommended to use an independent power adapter, and the output current of the power adapter (charger) is suitable to be larger, so that the charger can output more current when the mobile phone has greater charging power demand, and it also avoids the unstable output caused by the long-term high-load operation of the charger (the one with small output current).

How to store the lithium battery of mobile phone?

　　1. Occasionally fully charge and discharge, and reserve a certain amount of electricity.

　　Although there is no memory effect in lithium batteries, there is no need for deep charging and discharging every time, lithium batteries, like other batteries, will have an "inert effect". If the chemicals in the batteries often do not participate in the reaction (that is, they are often not fully charged), they will also lose a certain capacity. Therefore, if the mobile phone is not used for a long time, it needs to be fully charged/discharged occasionally (once every 3 months or so), while lithium battery storage should avoid full charge/zero charge, and it is best to have about 40% power.

　　2. Avoid high temperature storage and physical impact.

　　Mobile phone lithium batteries that have not been used for a long time should be placed in a cool place to avoid electrostatic fire caused by being too dry, and should not be placed in a place that is too humid, because temperature and humidity will make lithium batteries self-discharge. The recommended ambient temperature for storage is 0℃~20℃. In addition, metal hard objects should be avoided to be stored together with lithium batteries, because the shell of lithium batteries is more likely to be pierced by hard objects and damage the batteries.

Summary: mobile phone charging can be done at will without entanglement.

　　Although there are many tips for charging mobile phones, and the knowledge about lithium batteries is not only those in the article, for ordinary mobile phone users,Pay more attention when choosing a charger and pay attention to the fever of the mobile phone when charging, which can basically ensure the battery life and safety.Besides, smart phones are getting cheaper and cheaper now, and many people have changed their phones before the batteries break down, so why do we have to worry so much?

　　[Global Times Comprehensive Report] "What will happen if Trump imposes a 25% tariff on about $300 billion of China goods, as he threatened? A fireworks company in New Hampshire said that they can only raise prices, but this may lead to the loss of business and make some small towns give up the fireworks display on July 4 th. A Minnesota motorcycle company says it may lose to foreign competitors who don’t have to pay taxes on imported parts from China. A Los Angeles household products design dealer said that they can only suspend recruitment for a long time and postpone the plan to open a larger warehouse … …” On June 17th, when the U.S. Trade Office began to hold a hearing on China’s tariff plan, the U.S. government was almost drowned out by the opposition of a large number of domestic enterprises. The Associated Press listed only a few examples in the above report. The White House claims that increasing tariffs can benefit American goods, but many American companies say that this line will not work; The White House also said that this can increase fiscal revenue, but in fact most of the money is used to subsidize farmers. Who will benefit from the United States holding high the tariff stick against China?

　　Buy American goods instead of China? These American companies said they couldn’t do it.

　　According to the Global Times reporter, the hearing on the 17th started at 9: 30 local time. This round of hearing lasts for 7 days, from June 17 to 21 and from June 24 to 25. It is expected that more than 300 American enterprises will send representatives to testify. At present, the office of the US Trade Representative has received more than 1,200 written comments and applications for face-to-face testimony. Reuters said on 17th that this schedule means that Trump will start a new round of tariffs after July 2nd, because there will be seven days to submit the final rebuttal after the hearing.

　　"Buy American goods instead of China imports? Some American companies said they could not do it. " The US "Wall Street Journal" published an article on the 17th, saying that the office of the US Trade Representative has been flooded with letters from local companies recently. These companies ask the US government to give up the new round of tariffs on China, because they have no choice but to China.

　　Atlas PyroVision, a fireworks show company headquartered in New Hampshire, USA, now relies almost entirely on imported fireworks from China to provide fireworks shows for cities and sell fireworks products to consumers. Pelkey, CEO of the company, said that he had searched all over the world and "failed to find a supplier who could produce fireworks meeting the quality standards of China". He also said: "It would be great if I could get boxes of fireworks from American companies. Unfortunately not. "

　　Curtain importer S. Lichtenberg & Co stopped producing curtains and poles in the United States as early as 2007. Scott Goldstein, president of the company, said that restarting production was not considered. "I don’t even know if I can recruit sewing workers and how much I should pay them." He said that none of the American textile mills or printing and dyeing mills that used to supply cloth are now operating.

　　Regalo International LLC, a manufacturer of baby safety doors and crib railings, said that when the United States threatened to impose tariffs on China 18 months ago, they immediately went to Mexico and other countries to find new partners, but nothing was gained. Vietnam can accept orders for wood products and textiles, but "the metal manufacturing infrastructure is weak". The company said that factories in other countries are "far behind" China.

　　After analyzing the federal import data of the United States, The Wall Street Journal concluded that the goods affected by the new tariffs include 273 kinds of goods that account for more than 90% of China’s imports, such as electric blankets, fishing lines and fireworks. Last year, the total value of these goods imported by the United States from China was about $66.3 billion.

　　According to the British "Financial Times" reported on the 17th, the American Chamber of Commerce, the most powerful business group in Washington, submitted a strongly worded document to the Office of the US Trade Representative, saying that the new tariffs on China will greatly increase the harm that has been caused to American consumers, workers and enterprises. According to the American Chamber of Commerce, the tariffs imposed by the White House may cost the US economy $1 trillion in the next 10 years.

　　A retailer importing outdoor cushions and artificial Christmas trees in Kentucky told the media: "We want to tell you that the retail sector is preparing to be hit hard. We pray that the government will listen to God. "

　　Nearly 80% of American voters are worried about rising prices

　　William Lesch, a trade policy expert at the Center for Strategic and International Studies in the United States, believes that this round of tariff measures by the US government will cause "strong dissatisfaction" among the public, which is different from previous ones. He further explained to AFP that the tariff increase in July means that people will see the prices of various commodities rise when preparing to buy autumn goods, winter clothes and Christmas goods, and the pressure on ordinary consumers will be further enhanced.

　　The Associated Press quoted a report from the National Retail Federation of the United States on the 17th, saying that after the tariff increase, American consumers will spend $4.4 billion more on clothes, $2.5 billion more on shoes and $1.6 billion more on household appliances.

　　Germany’s "Focus" magazine said on the 17th that Trump was fighting a trade war for the 2020 general election, and he was playing a dangerous game. But will this really win the support of most American voters? The pro-Trump American media Fox News released an interview survey of 1,001 American voters on the 16th. According to the results, 45% of the respondents said that the tariff increase was harmful to the US economy, and only 33% of the respondents thought it was beneficial to the US economy. In addition, nearly 80% of the respondents are worried that prices will rise further due to tariffs.

　　"The White House said that imposing tariffs on imported goods from many countries can increase income, but in fact it doesn’t help, because most of the tax revenue is used to subsidize farmers affected by retaliatory tariffs." Singapore’s Lianhe Zaobao said on the 17th that after the US government imposed tariffs on China and other countries, it added $21 billion to the national treasury. But last year, the White House allocated $12 billion to help farmers, and this year, the related allocation is as high as $16 billion.

　　At the same time, the US government’s fiscal deficit is continuously expanding. According to a report in Singapore’s Straits Times on the 17th, although the US economy performed well last year and in the first three months of this year, some economic analysts predict that the US economy will slow down next year, and there may even be a recession. Last month, the US government’s fiscal deficit reached $208 billion, a year-on-year increase of 42%.

　　The Associated Press said that in the case that the US economy is already showing signs of fatigue, increasing tariffs will further weaken its economic development. Zandi, chief economist of Moody’s analysis department, said that increasing tariffs will lead to a reduction of 900,000 jobs in the United States.

　　"If the United States does not release goodwill, the Sino-US trade war will never end."

　　"Trump’s neglect of business groups will only make him suffer." CNN quoted Holtz Eakin, chairman of the American Action Forum, as saying, "Whether he can be re-elected depends on the economy. The uncertainty brought by tariffs and trade policies has negatively affected the good momentum of economic growth in 2018."

　　Chadwick, a businessman who imported silk scarves from China and sold them in Wyoming, wrote a passage to the US government, perhaps expressing the feelings of more Americans: "We ask, implore and pray that you use common sense in trade affairs and take care of the needs of small people! Buffalo fight, but it is us little ants who are trampled to death. "

　　"How the Trump administration hurts everyone." Deutsche Telekom said on 17th that Trump imposed punitive tariffs on China about a year ago, but this was only the beginning. Iran, Mexico, EU … … The U.S. government uses trade as a weapon everywhere and makes many naked blackmail words. However, this has also caused serious damage to the United States.

　　"No peace, no deal, no winner." The German newspaper Le Monde quoted Phil Bermel, director of the Institute of World Economics in Kiel, Germany, as saying that the Sino-US trade war will never end if the United States does not release its goodwill. In the long run, the trade war will cost both sides too much and the world will not be calm.

　　This morning’s press conference in the Central Committee of the Communist Party of China introduced the drafting of "the Central Committee of the Communist Party of China’s Proposal on Formulating the 14th Five-year Plan for National Economic and Social Development and the Long-term Goals for the Year 2035". A set of figures will show you →

　　A key

　　The planning "Proposal" was formulated under the personal leadership of the Supreme Leader General Secretary.

　　In March this year, the Political Bureau of the Communist Party of China (CPC) Central Committee decided that the Fifth Plenary Session of the 19th CPC Central Committee would consider the proposal of the 14th Five-Year Plan, and set up a document drafting group, with General Secretary of the Supreme Leader as the team leader and Li Keqiang, Wang Huning and Han Zheng as the deputy team leaders.

　　In the past seven months, General Secretary of the Supreme Leader has presided over two Politburo meeting of the Chinese Communist Party meetings, three The Politburo Standing Committee (PSC) meetings and two drafting group meetings to study and consider the overall framework, basic ideas, guiding principles and important contents of the draft of the Planning Proposal.

　　General Secretary of the Supreme Leader delivered a series of important speeches and made many important instructions to grasp the general direction, determine the general idea and put forward the grand strategy for planning the drafting of the "Proposal".

　　The General Secretary of the Supreme Leader personally made many in-depth investigations at local and grass-roots levels, personally listened to opinions and suggestions from all walks of life, personally revised the draft of the approval document for many times, made strategic planning, and devoted a lot of efforts to ensure that the drafting of the draft of the "Proposal" was completed with high quality.

　　An important feature

　　An important feature of the planning "Proposal" is to persist in promoting democracy, open the door and ask questions, and brainstorm.

　　At the end of last year, General Secretary of the Supreme Leader asked the CPC Central Committee and relevant departments in the State Council to organize preliminary research on the economic and social development during the 14th Five-Year Plan. The Central Finance Office and the National Development and Reform Commission entrusted more than 60 research institutions and relevant departments, including national high-end think tanks, to carry out research on 37 major topics, resulting in more than 130 research reports. The National People’s Congress and Chinese People’s Political Consultative Conference organized special research discussions and formed a series of research reports.

　　In March and August this year, the CPC Central Committee twice solicited opinions within and outside the Party, and the drafting group carefully studied and absorbed the opinions and suggestions put forward by various regions, departments and relevant parties.

　　At the beginning of August this year, the General Secretary of the Supreme Leader made important instructions to unify the strengthening of top-level design and the insistence on asking questions from the people, to encourage the broad masses of the people and all sectors of society to make suggestions in various ways, and to fully absorb social expectations, the wisdom of the masses, expert opinions and grassroots experience. Qi Xin worked together to compile the 14 th Five-Year Plan.

　　From August 16th to 29th, the drafting of the 14th Five-Year Plan was solicited for comments online, which was the first time in the history of drafting documents of the Central Plenary Session. The broad masses of the people actively participated, and there were more than 1 million online messages, from which more than 1,000 opinions and suggestions were sorted out.

　　From July to September, the General Secretary of the Supreme Leader presided over the symposium of non-party people, entrepreneurs, solidly promoting the integrated development of the Yangtze River Delta, experts in the economic and social fields, scientists, grassroots representatives and experts in the fields of education, culture, health and sports, and listened to opinions and suggestions from all sides in person.　

　　Five principles

　　First, handle the relationship between inheritance and innovation, and do a good job of organically connecting the goals of "two hundred years".

　　The second is to handle the relationship between the government and the market and give full play to China’s institutional advantages.

　　The third is to handle the relationship between openness and autonomy and better coordinate the two overall situations at home and abroad.

　　Xinhua News Agency, Harbin, May 17th Title: Perspective of a Extraordinary Online Gambling Case

　　Xinhua News Agency "Xinhua Viewpoint" reporters Chen Cong, Yang Xuan and Hou Ming

　　Recently, the Public Security Bureau of Jixi City, Heilongjiang Province successfully destroyed a mega-gambling criminal gang and found out that the funds involved were more than 1 billion yuan. It is reported that the gang set up an online gambling platform in 2016 to attract gamblers all over the country, and the crime time was as long as 7 years.

　　Criminal gangs arrested in mega-online gambling case.

　　"After a cross-border gambling criminal gang supervised by the Ministry of Public Security was destroyed, as required, we tracked the relevant information of more than 10 people involved in Jixi City. In January of this year, it was found that one of them had an abnormal capital flow, and many thousands and hundreds of dollars of funds were transferred out, and the time was in the middle of the night. " Yang Wenhao, the captain of the research and analysis brigade of the new network-related crime investigation branch of Jixi Public Security Bureau, said that this clue became the key to uncover the mega-online gambling case.

　　Following the flow of funds shown by this clue, more than 140 bank cards involved and a huge online gambling gang surfaced.

　　"We formed a joint arrest team to take action against the suspects." Yu Dan, deputy director of the new network-related crime investigation branch of Jixi Public Security Bureau, said that the joint arrest team was divided into two ways, and 26 suspects were arrested. Nine computers, 95 mobile phones and 62 bank cards were seized on the spot, and more than 23 million yuan of assets involved were seized according to law. Chen Mou, Huang Moumou and other criminal suspects confessed to the crime of participating in online gambling.

　　Yolanda, the captain of the second team of the new network-related crime investigation branch of Jixi Public Security Bureau, said that Chen Mou, the number one criminal behind the case, is from Fengshun County, Meizhou City, Guangdong Province. He is 43 years old and used to run his parents’ factory and run Internet cafes, tea houses and other businesses.

　　According to Chen Mou’s confession, in 2016, he heard that online gambling can make a lot of money, so he found Huang Moumou, the second principal in this case, and jointly planned to buy the terminal equipment needed to build a gambling platform. Later, Chen Mou recruited classmate Zhang Moumou and a neighbor to jointly prepare the mobile phone, computer, bank card, WeChat, Alipay account and rental house for the gambling platform. When the public security organs carried out the arrest, the gang only had more than 10 customer service personnel.

　　Chen Mou confessed that he made illegal profits of more than 12 million yuan in seven years. With the increasing gambling funds, the income of customer service staff of criminal gangs has been increasing, from the initial two or three thousand yuan per month to about 10 thousand yuan this year.

　　On April 5, the suspect was escorted to Jixi. (Photo courtesy of the respondents)

　　Yang Wenhao said that some customer service staff confessed that they had been cooks and taxi drivers before, and they joined the gang in order to make more money.

　　The seemingly easy game is actually manipulated by the backstage "Golden Finger"

　　The police investigating the case told reporters that the new online gambling game is very tempting, and criminals can manipulate the probability of winning or losing through the background.

　　Every step of the online gambling gang’s crime is precisely designed. The first step is to obtain a large number of mobile phone number information by illegal means, and then attract gamblers to participate in online gambling games by means of short messages, telephone calls, etc., with beautiful women chatting, huge rebates, and making money by swiping bills as bait.

　　"The promotion mode of the gambling platform at the beginning of its operation was mainly to carry out deception by purchasing personal information and sending mass mobile phone text messages. This method is more traditional, but it is very effective. " Yang Wenhao said that his words include "downloading a wealth management software to earn pocket money" and "playing fishing games can easily withdraw cash". After someone "hooked" the link to download the App, the customer service staff contacted and communicated with the gambler to guide them to enter the gambling game.

　　"There are relatively few types of online gambling games involved in this case, mainly including ‘ Fishing ’ ‘ Animal paradise ’ Etc., are very simple and easy to operate, attracting a large number of gamblers. " Yang Wenhao said.

　　"The core of this gambling game is to exchange gambling money for the game chip ‘ Points ’ Buy the opportunity to fish with guns in the game. If the gambler hits, he can win the corresponding ‘ Points ’ Then exchange it for cash. " Yang Wenhao introduced that this "fishing" game has no technical threshold.

　　"Gamblers will taste a little sweetness at first, but with the increasing investment, customer service will quietly use ‘ Goldfinger ’ — — ‘ Fishing ’ The difficulty of games is divided into four levels: simple, normal, difficult and dead, and the difficulty level can be adjusted in the background. " Yang Wenhao said that because the probability of winning or losing the game is manipulated by online gambling gangs, the total winning rate of gamblers who gamble for a long time is only 5%.

　　This is the crime tools and cash involved in the case seized at the arrest site. (Photo courtesy of the respondents)

　　Yang Bing, political commissar of the new network-related crime investigation branch of Jixi Public Security Bureau, said that similar online gambling routines are highly consistent: it is easy to get started. At the beginning, by setting a "simple" difficulty level, gamblers will win a few games; After being addicted, there will be a case of losing all the gambling money.

　　Strengthening source control to curb network-related crimes

　　Why can this gang continue to commit crimes for seven years?

　　According to the police investigating the case, the new online gambling has formed a complete industrial chain. Overseas servers and websites, domestic gambling sites, brokers’ websites serving gamblers, customer service personnel, third-party payment companies, various gamblers, etc. constitute the industrial circle of online gambling.

　　Jixi City Public Security Bureau has a clear hierarchy and well-organized criminal gangs. According to reports, criminal gangs are divided into pulling strings and customer service. Among them, Chen Mou and Huang Moumou, as managers, share the spoils according to the profit ratio. The customer service staff joined through the introduction of acquaintances, specifically responsible for the transfer of gambling funds, recharging virtual chips, and contacting gamblers. Customer service personnel rent residential houses as work dens, with three shifts and 24-hour online.

　　It is understood that the micro-signals and Alipay accounts used by the criminal gang’s customer service staff change on average once a month, and there is no correlation between different accounts. Their personal life numbers such as mobile phones and WeChat are separated from their work numbers. When the police arrested, they found that the customer service staff did not bring their own mobile phones with them. "Just the day before the suspect was arrested, the customer service workplace has just been replaced." Yolanda said that they are also very cautious about the choice of the workplace. The rooms next door and the upper and lower floors of the venue are generally uninhabited, and no one will open the door when knocking at the door. They remind each other to open the door through WeChat.

　　"To curb online gambling and telecom fraud, source control is the most critical." Yang Bing said that Jixi City has set up a joint conference office to crack down on telecommunication network fraud, controlled the "two cards" of mobile phone cards and bank cards, and controlled the opening of cards by outsiders and high-risk personnel to curb the occurrence of network-related crimes.

　　According to industry insiders, telecommunications, network information and other departments and institutions have stepped up inspections to identify, discover and block gambling apps and websites through technical means. "It is not difficult to block it in time. The key is to form a joint effort of government departments and banks, telecommunications and other institutions." Public security police in many places said.

　　The public security department reminded that the public should pay attention to protecting personal privacy, and at the same time constantly improve their awareness of prevention and anti-fraud ability, and stay away from all kinds of fancy gambling temptations. When you find that you are induced to enter the game, you should call the police in time to avoid property losses.

The fragrant rapeseed oil was poured on the beef slices covered with garlic spices, splashing countless small oil beads from jinliang, making a lively and beautiful sound. Sichuan cuisine brings the world a pleasant feeling between lips and teeth and a hot taste experience.

The historical and cultural development of Sichuan cuisine not only benefited from the superior natural conditions and the developed agriculture in Sichuan, but also experienced the collision and integration of new cultures brought about by many immigrants, and there were several innovations in both taste and seasoning. Today’s Sichuan cuisine focuses on "fresh and spicy", and at the same time has the flavor characteristics of "one dish, one grid, one hundred dishes and one hundred flavors". Different regions have also developed special dishes related to local culture, living habits and products.

The development of the times and the construction of the twin-city economic circle in Chengdu-Chongqing region have also promoted the blending of catering in the two places. Sichuan cuisine is more widely loved for its spicy and spicy flavor, and the catering industry in the two places has also ushered in a new stage of mutual assistance, symbiosis and integration, opening a new development pattern of multi-terminal market integration.

Song Shichuan Hotel, which likes to add sugar to ancient Sichuan cuisine, is unique.

Every major development and innovation of Sichuan cuisine is basically related to large-scale immigration. The ancient Shu state more than 3,000 years ago was centered on the capital city of Longyi, with a warm climate and developed agriculture. During the Warring States Period, Li Bing, the commander of Shu County, built Dujiangyan Water Conservancy Project, which fundamentally solved the flood problem and ensured the sufficiency and richness of ingredients. In addition, before and after the reunification of Qin, people immigrated to Bashu, which made Sichuan cuisine gradually form its own characteristics.

According to the records of "Four Seasons Food System" and "Imperial Court Letters" in the Three Kingdoms period, fish dishes had appeared at that time, and people liked sweetness, adding honey to meat to enhance flavor. The Records of Huayang in the Eastern Jin Dynasty mentioned the characteristics of Sichuan cuisine, such as "respecting taste" and "good spicy flavor". The overall taste of the dishes is bright, and I like to season with pepper.

In the Tang and Song Dynasties, Li Bai, Su Shi, Du Fu, Lu You and others also expressed their love for "Sichuan food" through a large number of poems, which made us understand that "spicy" was not the main feature of Sichuan food at that time. Li Bai praised the stewed duck, Du Fu’s creation of "five-gorged fish" and various snacks, as well as the Southern Song Dynasty’s "Dream of Tokyo" record that "there are more Sichuan restaurants, but there are noodles with meat, large and small noodles with meat, fried pork, miscellaneous fried events, cooked and cooked rice", all of which confirmed the uniqueness of Sichuan restaurants at that time, except eating in the south and eating in the north.

Steamed duck upgraded Taibai duck

The war in Ming and Qing Dynasties greatly reduced the population in Sichuan. After the unification of the Qing government, the movement of "Huguang filling Sichuan" gradually restored the population and economy in Sichuan, and greatly changed the eating habits and culture. Coupled with the promotion and planting of newly introduced ingredients such as pepper, corn and sweet potato, the use of new seasonings such as Pixian watercress has also emerged, and a variety of flavors and dishes have emerged, which has evolved into a new situation of "one dish, one grid, and hundreds of dishes".

Rong cuisine is elegant, Chongqing cuisine, Jianghu Chengdu-Chongqing cuisine has distinctive characteristics.

Sichuan cuisine is diverse, harmonious but different. Among them, Chengdu cuisine is generally similar to Chongqing cuisine, mainly in cooking techniques and tastes. Chengdu cuisine is elegant and light, paying attention to inheriting traditional taste, and spicy taste is not the main thing. Chongqing cuisine is more bold and spicy, and is willing to innovate and accept new dishes, which is more Jianghu temperament. The difference in emphasis is also related to many factors such as the culture of the two places.

Chengdu has developed its commerce since ancient times, and has also formed a perfect market structure that adapts to various consumption levels and tastes. It can be roughly divided into two kinds: popular dishes and banquet dishes. Popular dishes are spicy and spicy, and banquet dishes are mainly salty, juicy and delicious.

Exquisite Chengdu cuisine

In modern times, a large number of foreign officials, wealthy businessmen and people from all walks of life entered Sichuan, which also brought a variety of foreign flavors, blended them with Sichuan cuisine, and enhanced the delicacy of dishes on the basis of retaining traditional Sichuan cuisine. During this period, "Mansion Cuisine" with Chengdu characteristics was born. "This is because the owner of the mansion is very particular about food and clothing, and the pursuit of cooking skills is even more’ not tired of eating fine and fine’, so there is a mansion dish." Qu Xiaoqiang, editor-in-chief of Sichuan Folk Culture Grand Ceremony, explained that orange, cordyceps, duck and braised pork in mash are all classic old mansion dishes.

Chongqing is located at the intersection of Jialing River and Yangtze River, and its historical and cultural development is closely related to the waterfront wharf. Between the bow of the river bank and the bow of the river, various occupations such as porter, dockworker, water bearer, club and so on were born, which gradually formed an open, inclusive and advancing with the times dock culture, and the character of Chongqing people became more and more generous in honest and frank, and these characteristics were also reflected in Chongqing cuisine.

Chongqing Tongxin yuan Yuanyang hotpot

Chongqing hot pot, Chongqing Jianghu dishes, Chongqing Xiao noodles, etc. all have very obvious characteristics of "hemp, spicy, fresh, fragrant and tender". Chen Xiaolin, a senior expert in Chongqing’s food culture, also summed up the characteristics of Chongqing’s Jianghu dishes in "Chongqing Jianghu dishes", such as flamboyant seasoning personality, thick oil, rough and natural raw materials, strange cooking skills and strong Jianghu flavor.

Facing various challenges together and working together to strengthen the influence of Sichuan cuisine

With the impact of diverse diets and unclear understanding of the concept of Sichuan cuisine, Chengdu-Chongqing’s rich food culture needs to be further excavated and passed down. Under the development opportunity of the construction of the twin-city economic circle in Chengdu-Chongqing area, the communication between the two places has become more and more frequent. Nowadays, you can eat authentic Chongqing hot pot, Jianghu dishes, small noodles and other Chongqing specialties in Chengdu, and you can also find many restaurants specializing in Chengdu exquisite Sichuan cuisine and Zigong Yanbang cuisine on the streets of Chongqing, which promotes the exchange and learning of Sichuan-Chongqing catering and makes up for the lack of common development of enterprises in the two places in previous years.

However, the development of Sichuan-Chongqing catering still faces many challenges. First, the impression of foreign tourists on Sichuan cuisine is getting thinner and thinner. The most famous ones are hot pots and skewers, which do not show the richness of Sichuan cuisine. The second is the weakness of branding. Sichuan cuisine is found everywhere, but there are very few representative brands. Under such circumstances, further strengthening cooperation and communication between Sichuan and Chongqing, and holding a group development are also the key points that catering people in the two places need to think together.

In order to implement the work requirements related to the construction of the twin-city economic circle in Chengdu-Chongqing area, strengthen exchanges and cooperation between Chengdu and Chongqing, promote the integrated development of Sichuan-Chongqing catering industry, talk about the innovative path of Chengdu-Chongqing catering industry, and build the cohesive force of Chongqing catering industry. The "Centripetal Joint Force 2023 Chengdu-Chongqing Catering and Drinking Integration Development Summit Forum" will be held at Chongqing International Expo Center on October 27th. The forum is directed by Chongqing Municipal Commission of Commerce, sponsored by Cover News, Huaxi Dushi Bao and the 15th China (Chongqing) Hotpot Food Culture Festival Organizing Committee, and assisted by Chongqing Hotpot Association and Sichuan Gourmet Association.

　　Beijing, May 9 (Reporter Zhang Ni) Recently, the nine-valent cervical cancer vaccine (HPV vaccine) was approved for listing in China, bringing good news to many women. HPV vaccine is the first vaccine in the world to include cancer as an indication. However, for many domestic people, this vaccine is still new, and the popularity of related knowledge is still limited.

　　How to vaccinate? How to choose the vaccine type that suits you? What preparations need to be made before vaccination? A few days ago, the reporter from Zhongxin. com interviewed Zhao Yun, deputy chief physician of gynecology department of Peking University People’s Hospital, on a series of issues of public concern.

　　— — What is the relationship between HPV virus and cervical cancer?

　　HPV is the abbreviation of the English name of "human papillomavirus". There are many members in the HPV family, and a few of them are closely related to malignant tumors, so they are called high-risk HPV. From the statistics of large population samples, 99% of cervical cancer is caused by infection with this kind of virus.

　　The main route of transmission of HPV virus is through sexual contact, and mucosal contact can also be transmitted.

　　When there is no sexual exposure, the probability of this virus infection is almost zero, but the probability of HPV infection in women who have sex is very high. About 70% to 80% of women may have been infected with this virus, especially when they are sexually active (usually before the age of 30), which is the peak of infection.

　　However, many infections are transient infections. With the increase of age, these viruses will be cleared away, and only a small number (10-15%) are in a state of persistent infection, which is the high-risk group of cervical precancerous lesions and cervical cancer.

　　— — What is the difference between bivalent, tetravalent and nonavalent vaccines?

　　At present, there are three kinds of HPV vaccines listed in the world: bivalent, tetravalent and nonavalent.

　　A bivalent vaccine can prevent infections caused by HPV16 and HPV18 viruses. International research data show that more than 70% of cervical cancer is caused by these two viruses.

　　The tetravalent vaccine can prevent the infection of HPV6, 11, 16 and 18 viruses. Although HPV6 and HPV11 are not high-risk HPV viruses of cervical cancer, they can cause condyloma of lower genital tract.

　　Nine-valent vaccine is aimed at nine subtypes of HPV6, 11, 16, 18, 31, 33, 45, 52 and 58. Studies show that nine-valent vaccine can prevent 90% of cervical cancer.

　　It should be pointed out that HPV vaccine can not prevent cervical cancer 100%, even after vaccination, cervical cancer screening should be carried out regularly.

　　— — What is the difference between the three vaccination ages?

　　In terms of vaccination age, the approved vaccination age in China is: bivalent vaccine is suitable for women aged 9-25, tetravalent vaccine is suitable for women aged 20-45, and ninevalent vaccine is suitable for women aged 16-26.

　　The division of age groups is determined based on the results of clinical experiments of different age groups in China. HPV vaccine is a preventive vaccine. At present, no results show that it has the effect of preventing diseases for people who have been infected with HPV virus contained in the vaccine. Therefore, population vaccination before sexual exposure has the best health economic effect.

　　In the position paper updated by WHO in May 2017, it is suggested that women aged 9-14 who have not had sex should be the main target population, and women over the age of 15 should be the secondary target population.

　　— — Is the applicable age of nine-valent vaccine in Hong Kong 9-45 years old?

　　The instructions for the nine-valent vaccine in Hong Kong are applicable to 9-45 years old. However, there is no clinical data on the effectiveness of using HPV nine-valent vaccine in people over 26 years old.

　　Hong Kong’s approval of the application for the elderly is mainly based on the effectiveness of the tetravalent vaccine for the elderly population. The nine-valent vaccine and the tetravalent vaccine are immune-bridged, so the application range is 9-45 years old.

　　— — Is it still useful to vaccinate married and fertile women?

　　Some married and fertile women have not been infected by the virus, or have not been infected by the HPV subtype contained in the vaccine. At this time, vaccination is also effective.

　　— — How many times does the vaccine need to be vaccinated?

　　The bivalent, tetravalent and nonavalent vaccines all need to be injected in three times and completed within six months.

　　Among them, bivalent vaccine is recommended to be inoculated in October, January and June, with a total of 3 doses. The second dose can be inoculated 1-2.5 months after the first dose, and the third dose can be completed 5-12 months after the first dose.

　　Four-valent and nine-valent vaccines are recommended to be vaccinated in October, February and June, with a total of three doses. The interval between the first dose and the second dose should be at least one month, and the interval between the second dose and the third dose should be at least three months. All three doses should be completed within one year.

　　— — Is it still necessary to vaccinate with nine valence after vaccination with four valence?

　　At present, there is not enough evidence to prove that it will be more beneficial to vaccinate another series after completing one series of vaccines.

　　From the clinician’s point of view, women who have been vaccinated with one of bivalent, tetravalent and nonavalent vaccines and completed all injections can prevent more than 70% of cervical cancer. Another HPV vaccine injection is not recommended.

　　The instructions for the nine-valent vaccine mentioned that after the third dose of tetravalent HPV vaccine was inoculated, the nine-valent vaccine was injected at least 12 months apart.

　　— — How long is the vaccine valid?

　　Bivalent and tetravalent vaccines have been on the market for more than ten years. At present, the research data show that the antibody level of the vaccinated population is still at a high level, and there is no evidence that it is necessary to strengthen vaccination.

　　The nine-valent vaccine was launched in 2014. Studies on people aged 9-15 and 16-26 showed that serum antibodies remained positive in the fifth year after vaccination. At present, there is no evidence of the need for intensive vaccination.

　　— — What tests should I do before vaccination?

　　No special examination is needed before vaccination. However, in my personal opinion, people who have been sexually exposed and have never been screened for cervical cancer before should be screened. The purpose of screening is to know whether they have cervical lesions.

　　— — Which groups are not suitable for vaccination?

　　People who are allergic to the active ingredients used in the vaccine or any dressing adjuvant should be prohibited from using it. People who have had hypersensitivity after injecting HPV vaccine should not be vaccinated again.

　　In addition, women who are pregnant and pregnant are not recommended to be vaccinated now. Although a large number of practices that have been put on the market have proved that there is no data showing that the vaccine will affect the growth and development of embryos, pregnancy preparation and pregnancy are special periods, so it is not recommended for such people to be vaccinated immediately.

　　— — What are the side effects of the vaccine?

　　At present, the safety of the vaccine is still very good. Vaccination of this kind of vaccine is the same as other vaccines. The common systemic adverse reactions are mainly headache, fever, nausea and dizziness, and the local adverse reactions are mainly pain, swelling, erythema and itching.

　　— — Can men be vaccinated?

　　At present, all vaccines approved in China are used by women to prevent cervical cancer.

　　In foreign countries, tetravalent vaccines approved by some countries can be used for male vaccination. Male vaccination can also prevent precancerous lesions of some reproductive organs, condyloma and so on.

　　In addition, male vaccination is beneficial to the emergence of group immune effect, which reduces the overall infection rate of HPV virus in the population.

　　— — What are the precautions for preventing cervical cancer?

　　To prevent cervical cancer, in addition to vaccination, regular screening should be conducted, especially for women who have had sexual exposure.

　　For healthy people under the age of 30, it is suggested that only cell screening should be carried out. If the screening result is negative, it can be checked again after 3 years. For healthy people over 30 years old, it is recommended to carry out cell screening and HPV virus examination. If the results are double negative, they can be examined again after 5 years.

　　Early sexual exposure, many sexual partners, active sexual behavior and unclean sexual behavior are all high risk factors for cervical cancer, so condoms are recommended for safe sex. In addition, developing a healthy lifestyle is also beneficial to the prevention of diseases.
