　　The problem of credit card theft is becoming more and more common in China, and it has a long history abroad. What is the development trend of foreign credit card theft cases? What are the advanced experiences of foreign cardholders, banks and regulations in dealing with stolen brushes? In the last issue of the "Focus on Credit Card Stealing" series, we invited our reporters in Britain, the United States and Germany to take us to find out by combining interviews with our own experiences.

　　Britain:

　　Develop biotechnology

　　Identify consumer behavior

　　Lucy Nagling, press officer of the UK Anti-Financial Fraud Action Group, told reporters that financial fraud in the UK in 2015 caused a total loss of 755 million pounds, an increase of 26% over the previous year. Among them, the financial loss caused by stolen debit cards and credit cards or information leakage was 567 million pounds, an increase of 18% over the previous year. Nagling said that these increasing data show that Britain is facing severe pressure to crack down on financial fraud. In particular, the increasingly complex network attacks, Trojan horse implantation, data theft and other behaviors make financial fraud more difficult to prevent and combat.

　　According to the survey of the UK Anti-Financial Fraud Action Group, in 2015, there were mainly the following types of financial fraud in the UK. The first is to pretend to be a bank, a police officer, or a government public department, make a phone call or send a text message or email, and get the user’s bank card or credit card information. Its excuses usually include paying an emergency expenditure, refunding a certain fee, and upgrading an account. Different from the domestic bank card "password verification can be set for online or offline consumption", credit cards in the UK are generally used for direct credit card consumption or signature consumption. If you use a credit card or debit card through the Internet or telephone, there is still no password setting. Generally, you only need to provide the card number and the 3-digit number printed on the back of the card. Therefore, if the personal card number and the three digits on the back are leaked, it will be easily stolen by others.

　　When the reporter first came to Britain, he was repeatedly reminded by his friends that he must not easily tell others the bank card number and the three digits on the back. On weekdays, reporters also received many calls for payment, some from formal large enterprises, such as power companies; Others can’t confirm the authenticity of their identity. In this case, it is safer to refuse to pay by phone and log in to the official website to pay.

　　The second common type of fraud is stealing and copying bank card information. The timing of the attack is often when the cardholder operates at an ATM or POS machine, or swipes the card to shop.

　　The third common type of fraud is the increasing network attacks and thefts, which are often committed through links with Trojans and fake websites.

　　In the face of endless financial fraud tricks, British banks and relevant regulatory authorities are committed to studying and adopting newer and better preventive measures. According to reports, the security system adopted by the Bank of England in 2015 prevented about 70% of fraud. Some of these measures include: developing new security tools, especially biometrics, consumer behavior identification technology, etc. If the recent trading behavior of an account is quite different from usual, it will contact the customer in time for confirmation; Strengthen cooperation with government departments, financial regulatory agencies and other relevant units to jointly crack down on financial fraud and ensure timely communication of information and data; Use various methods to remind users to pay attention to cultivating account security awareness and prevent financial fraud.

　　Tony Black, senior investigator of the Credit Card Crime Investigation Team of the UK Anti-Financial Fraud Action Group, called on: "It is very important for users to remain vigilant. If you receive a phone call, text message or email asking for your personal information, please don’t reply easily. You must ensure that the other party is trustworthy, for example, you can verify it through the authorities. Otherwise, it is best to ignore it. "

　　In addition, the official websites of major banks in the UK have information to remind cardholders to use bank cards and credit cards safely, including: personal information related to accounts should not be disclosed to anyone; Be sure to pay attention to whether the website is safe when shopping online; Check the bank statement regularly, be aware of your own consumption, and notify the bank in time if you find any suspicious signs; Receipts, bills and invoices after swiping the card at ordinary times should be properly kept.

　　At present, all major banks in the UK have opened 24-hour customer service telephones. After discovering that the credit card has been stolen, as long as you call the bank, the account will be closed and the staff will check it and send a new card.

　　United States:

　　Spot check customer identity

　　Stealing brushes costs a lot.

　　Major banks in the United States have different preventive measures to prevent credit cards from being stolen in large quantities and continuously. Take the Bank of America credit card used by the reporter as an example. If the banking system detects abnormal consumption of the credit card, it will send a short message and temporarily freeze the credit card. Every time a reporter goes on a business trip in a foreign country and spends twice with a credit card, it will be temporarily frozen. The bank sends the latest consumption record through SMS, and the bank will lift the freeze after the cardholder confirms it.

　　There are also strict regulations on the use of credit cards in the United States, and it is not allowed to use other people’s credit cards to spend money, even for a family. Merchants will check the identity documents of consumers from time to time, and once they find that the identity of the cardholder is inconsistent with that shown on the credit card, they will refuse to accept the card.

　　If the cardholder reports the stolen credit card to the bank, the bank will freeze the card in time and send a new card to the cardholder, and the cardholder does not have to bear the loss. At the same time, the bank will ask the cardholder to call the police and find out the truth by checking the signature. Most banks buy credit card insurance, and the compensation for cardholders is ultimately borne by the insurance company, so there is no reason for banks not to protect the rights and interests of cardholders.

　　If the cardholder has any objection to the consumption, calls the bank and the bank trusts the customer, then the disputed amount will be returned to the cardholder first, and then communicated with the merchant. Of course, if it is finally determined that it is the fault of the cardholder, the cardholder will have to pay the full amount of consumption and even pay interest.

　　In the United States, stealing other people’s credit cards is a serious crime, and the punishment measures stipulated by each state are different, but they are generally more severe. In Virginia, where the reporter is located, the law stipulates that stealing someone else’s credit card can be fined up to $10,000 and imprisoned for 20 years. In the face of severe punishment measures, the cost of stealing other people’s credit cards is very high, and most people dare not easily break the law.

　　If the cardholder conceals his own consumption and maliciously deceives the bank, the cardholder will not only compensate and bear legal responsibility, but also record his behavior in the credit system. Once you have a bad credit record, all aspects such as applying for a credit card and buying insurance will be affected, which can be said to be difficult.

　　Germany:

　　The insurance mechanism is sound

　　Someone pays for the loss.

　　German credit cards have always adhered to the principle of "convenience for cardholders". Except for a small number of bus ticketing machines, you need to enter the PIN code, and most of the counter consumption can be done by signing. In some parking lot payment machines, the card is directly deducted without any verification after being inserted.

　　Although the use of credit cards in Germany does not require a password, and cashiers rarely check their signatures carefully, thieves are not "cold" about it. There are many cases where the wallet is stolen and the cash is lost, but the credit card is intact. The reporter has experienced it personally. German police once explained to reporters that no matter whether they are operating in machines or shopping malls, most of them are equipped with cameras nearby, which will definitely leave traces of the time and place of consumption, so thieves will not "take this big risk".

　　High convenience is always accompanied by high risks. Although thieves dare not steal credit cards in public places, cyber hackers can hide behind the screen and commit crimes. Since most credit cards in Germany don’t popularize SMS consumption reminder service, theoretically, as long as you know the cardholder’s name, card number, 3-digit security code on the back of the card and the expiration date, you can make any consumption online. This is not difficult for network hackers.

　　During the one and a half years in Germany, the reporter was forced to change three credit cards because of this kind of network theft. In the worst case, thousands of euros were stolen, and a large amount of money was spent in Shanghai, Dubai, Paris and other places within one day. Finally, the reporter learned that the card was stolen because the bank became suspicious and stopped the card and informed the reporter.

　　However, cardholders who have been stolen should not be too flustered. When the cardholder contacts the customer service of the credit card or goes directly to the bank counter to complain, the bank will ask the cardholder to explain the actual use of the credit card in person or in writing, and sometimes make a preliminary verification. After it is confirmed that the hacker forged the consumption record, the bank will ask the cardholder to fill in the compensation complaint form and send it back to the complaint acceptance center, which can generally eliminate the stolen payment on the next settlement date. As far as the reporter’s experience is concerned, it generally takes no more than three weeks from the bank accepting the complaint to eliminating the stolen debts, and there will be no stalemate or dispute between the bank and the cardholder. As long as it can be proved that the stolen brush is not caused by personal negligence such as losing the card, the cardholder will appeal successfully.

　　The reason why cardholders and banks can be so calm is related to the perfect credit card insurance mechanism. According to the staff of the German Savings Bank, banks will make huge investments in credit card insurance every year. With "all risks", the bank can claim compensation from the insurance company, that is, the stolen money will eventually be paid by the insurance company. The insurance company will further let its investigation team investigate and contact the police. In addition, Germany has a "lawyer’s insurance" that can pay the lawyer’s fees for prosecution and police investigation. The monthly cost is about tens of euros, and most people will buy it. Cardholders will generally cooperate with banks, report to the police and go through legal procedures to bring the real murderer to justice.

　　Despite this, the German police told reporters that most of the hackers are international criminals who operate remotely across borders and are often difficult to track down. This may be one reason why most Germans don’t like credit cards.

Editor’s note: This article comes from WeChat WeChat official account’s "New Consumer Daily" (Daily”(ID:NewConsumerDaily), and is written by Sober Zhang, published by 36Kr with authorization.

The winter solstice has passed, and the temperature in China is decreasing day by day, but one area is heating up: the hot drink market, especially the "self-heated drink".

From coffee and milk to milk tea and red wine, all kinds of drinks can be self-heated. What is the current performance of "self-heated drinks" in this winter limit? Who will buy "self-heating drinks"?

First of all, since the winter of 2020, the new consumer Daily has observed that three different brands have successively launched three different categories of self-heating drinks, covering milk, coffee and red wine.

At the end of November, Nongfu Spring’s charcoal coffee launched a self-heating set, which was equipped with a self-heating cup+self-heating bag set.

The self-heating principle of this self-heating coffee is similar to that of the self-heating chafing dish. The user will put the self-heating bag into the self-heating cup, inject a certain amount of water, then put in the drink, cover the cup and wait for 6-8 minutes to complete the "self-heating" process.

On December 7th, Jin Dian, a high-end dairy product, announced that it would launch a self-heating milk gift box.

It is understood that the self-heating mode of this product is "wireless hot charging" mode, which can heat the milk at 55 degrees Celsius in 15 minutes and keep the constant temperature for 3 hours. However, as of press time, this product has not been sold in its official flagship store.

At the beginning of the month, the founder of the wine brand Zui Goose Niang wrote in his official Weibo that Zui Goose Niang launched the "first self-heating jar of red wine in the universe". Just press the bottom button and shake the bottle immediately, and you can get a cup of hot red wine with appropriate temperature.

In addition to some new self-heating drinks in the winter of 2020, in 2019, there was such a little-known self-heating milk tea on the market: antler tip.

It is reported that the heating method of this self-heating milk tea is still using self-heating bag heating, which will provide consumers with "self-heating" necessities such as self-heating bag+purified water+tea powder bag+straw.

Compared with the self-heating drinks that have been born in the past month, "self-heating" is not a new word, but when most of us mention the word "self-heating", they are often followed by food such as "hot pot" and "covered rice".

Looking back at 2020, which is coming to an end, "self-heating" has also led the trend of the food market.

The outbreak of the epidemic at the beginning of the year made self-heating hot pot, self-heating rice and other self-heating foods popular in every household. This is a joy beyond the "epidemic" of the self-heating market. After the heat, it also attracted capital injection: in May 2020 alone, cannibals and Mo Xiaoxian, two food brands with self-heating hot pot as their main products, completed tens of millions of A rounds of financing, and Zigui Pot completed more than 100 million yuan of B rounds of financing in May.

Although compared with the heated self-heating food market, drinks are lacking in the self-heating market, to some extent, self-heating drinks are located between the self-heating market and the ready-to-drink hot drink market.

However, after the appearance and fierceness of self-heating food made consumers more familiar with the concept of "self-heating", "self-heating beverage" met the booming hot beverage market in China.

According to public information, the scale of hot drinks market in China has exceeded 100 billion yuan, covering soybean milk, fruit juice, original tea beverage, milk tea, coffee, almond dew, walnut dew and so on. At the same time, the 2018 consumer beverage temperature preference index shows that 54.7% of consumers will choose hot drinks as drinks in winter.

Although for most beverages, the cold winter is often the off-season, consumers, especially those in China, obviously have a demand for hot drinks, and brands have also realized this and started to meet the needs of consumers.

According to the observation of the new consumption Daily, both the cutting-edge beverage brands and the traditional beverage companies have made different layouts for the (ready-to-drink) hot beverage market:

Yuanqi Senli introduced a new product of Yuanqi forest milk tea mini, and the package was thickened and reinforced with multiple ribs, which greatly improved the heat resistance and stability of the bottle and could meet the needs of beverage heating.

Since October 2020, Coca-Cola Company has successively introduced a variety of hot drinks in winter, including Coca-Cola Ginger+,COSTA Cafe Family English black tea latte milk tea drink, Minute Maid cinnamon warm pear fruit drink, etc.

Suntory Beverage also launched an upgraded series of warm drinks in winter, including sweet-scented osmanthus-flavored Liqu milk tea, honey-scented fruit tea, classic sugar-free oolong tea, Liqu latte and other products.

It can be seen that although the beverage market has entered the stage of fierce competition, there is still a broad market for ready-to-drink hot drinks.

After all, in the current development of ready-to-drink hot drinks, no single product or brand has ever become bigger and stronger, and it can successfully seize the big cake under the appearance of the so-called "off-season of winter drinks". As long as the demand has not been met, there will be unlimited market potential. Coca-Cola, Nongfu Spring and Yuanqi Forest all have insight into this. As far as the current development is concerned, the market of "self-heated drinks" can be said to be "blank".

After talking about the market, let’s look at the audience. To some extent, the "high-order demand" of consumers also gives the space for the emergence and development of self-heating drinks.

First of all, as the beverage temperature preference index shows, consumers in China always prefer warm or normal temperature foods and beverages, because they are considered to be less irritating to the digestive system and beneficial to health.

Secondly, self-heating drinks allow consumers to achieve "hot drink freedom" to some extent.

In particular, compared with the traditional method, you need to find water by yourself and brew it by yourself before you can get the fragrant, delicious and isokinetic products of hot drinks.

When you walk on the street where you can’t find a convenience store, take out a cup of self-heating milk from your bag; Or in the early hours of overtime, take out a cup of self-heating coffee. To a certain extent, this has expanded and provided consumers with more convenient hot drink usage scenarios.

Now, let’s briefly understand the "long" and "simple" history of self-heating drinks.

The reason why it is "long" is that self-heating drinks have actually appeared in the market for nearly 20 years. In 2001, the old coffee giant Nestle developed a "self-heating" coffee drink called "Nescafe Hot When You Want".

The principle is that water and quicklime are placed in the interlayer of the tank respectively, and heat is generated through chemical reaction. After pressing the button at the bottom, consumers can drink 60-degree hot coffee within three minutes.

However, after the market test, the heat of this self-heating tank will not meet the demand in cold weather; Moreover, the equipment occupies a large container, with only 7 ounces of coffee in an 11-ounce container, which makes consumers disappointed.

In the end, just one year later, Nestle gave up this product.

With the rapid development of the "self-heating" market in recent years, more and more beverage companies have begun to explore new directions of self-heating drinks, and more and more self-heating black technologies have begun to appear in the beverage market.

For example, in 2017, HeatGenie, a developer of self-heating technology, developed a self-heating canned beverage. Its self-heating equipment used aluminum and silicon dioxide with safer and more efficient heat energy as reaction heat sources, and the heating materials of the new self-heating technology only accounted for one tenth of the bottles and cans.

In 2018, the company received $6 million in financing. In 2019, it was renamed as HeatGen, which upgraded its new appearance and heating method. It can start heating by upgrading from the previous rotating bottle cap to the rotating bottom cover. When the temperature is suitable, it can stop heating by pulling the can ring.

Pull the timeline back to the present, 20 years later, when the technical problem of self-heating drinks is no longer a problem, what about their market performance?

The self-heating red wine of Drunken Goose Niang was sold in limited quantities. Although it attracted attention when it was launched, a month later, this convenient self-heating red wine did not cause a "sensation" in the market.

Nongfu Spring’s self-heating coffee and self-heating cup have been partially praised, but it is inevitable that some consumers will leave a message saying: "The taste of coffee after heating is average, and the acidity and bitterness are relatively dull. The self-heating cup is too simple. " And "not bad, how to say, more heating, less a bottle. "Equal evaluation;

As for Jin Dian, the milk gift box with black technologies such as intelligent identification and unlimited hot charging was promoted on December 7th, but before the press release, this Versailles milk has not been officially sold.

Finally, the self-heating milk tea that appeared in 2019, now open Taobao to search for "self-heating milk tea", can not be said to have disappeared, but obviously there is no sense of existence in the market, in fact, the reasons can be traced.

The laudatory name is "self-heating milk tea", but to some extent, it is still old wine in new bottles. After all, when you want to drink a cup of hot milk tea, you need to finish it: take out the milk tea, open the package, tear open the self-heating bag and the bagged water, and then finish the brewing. The above series of operations are obviously too complicated, and it can’t even be called that milk tea is "self-heating". It is better to brew a cup of fragrance to save time and effort.

This is why the history of "self-heating drinks" is "simple": Nestle self-heating coffee, which was scrawled in 2001, or antler tip self-heating milk tea, which was "tepid" two years ago, and milk, red wine and other products with mediocre market performance now.

Although instant hot drinks are a new trend, the function of "self-heating" has not aroused much splash in the market.

"If the whole world uses the same old method to create wealth, it will not create wealth, but a disaster." In "From 0 to 1", PayPal founder peter teale said.

Undeniably, the innovation and appearance of self-heating drinks have met the needs of some segmented consumers, expanded the scene of ready-to-drink hot drinks to some extent, and filled the gap in the market of self-heating drinks.

However, judging from the performance of self-heating drinks in the past 20 years, it is not difficult to understand why such a product that meets the segmentation field has not become an "explosive product" in the end: self-heating drinks can only meet the needs of a limited group of people within a limited time and in a limited way.

At the same time, even simple ready-to-drink hot drinks require sufficient investment in materials, channels and configurations, not to mention "self-heated drinks" that require a higher technical threshold.

It is precisely because of this "limitation" and "high threshold" that for many big brands, self-heating drinks may be just a way for them to try to be closer to consumers and use the gimmick of "self-heating" to market and increase market volume. But after all, it is: it is tasteless to eat, and it is not a pity to abandon it.

For some young brands, self-heating drinks can’t be their main source of revenue, and the hunger marketing method of "limited sale" may be the best choice.

"The demand for hot drinks is mainly concentrated in winter and spring. According to different geographical locations, there are regional differences in the peak sales. The peak sales of hot drinks in the north can last for about 6 months, and the area south of the Yangtze River is basically about 3 months. Whether it is for the offline warm cabinet layout, channel implementation, or the product itself, (hot drinks) put forward higher requirements for us. " This is the Coca-Cola Company’s consideration for the layout of "hot drinks".

If the warm drink in winter is widely expected and the warm drink market still has certain potential, then after the uproar, the drink that can realize "self-heating" is only a false proposition.

Yangcheng Evening News Reporter Liu Xinyu and Xue Renzheng reported that May 11th is the World Obesity Prevention Day. The "meal replacement diet" is particularly popular in spring and summer every year. According to the data of "Shop Monster", the daily sales volume of meal replacement products can even reach 100,000+,and the unit price ranges from 28-140 yuan. Many netizens who tried to lose weight with meal replacement products said that they didn’t lose weight after eating many meal replacement products and spent a lot of money. The reporter interviewed Deng Yuhong, director of the Clinical Nutrition Department of the Second Affiliated Hospital of Guangzhou Medical University, and obtained the "meal replacement" data of 145 obese people to see the real effectiveness of meal replacement to lose weight.

　　Data:

　　Meal replacement is really effective in losing weight.

　　Deng Yuhong introduced that in hospital clinical practice, meal replacement (mainly in meal replacement powder) is indeed an auxiliary means to lose weight.

　　This assistive device was also completely recorded by her team and published in the journal of General Medicine of China. The team took 145 patients (36 males and 109 females) who came to the hospital from June 2015 to January 2017 as the research object, with an average age of (34.2 10.9) years and a body weight of (81.09±15.84)kg. 28.0kg/m2）。

　　The whole weight-loss experiment lasted for six months, and the purpose was to study the weight-loss effect of the diet mode with low carbohydrate and high nutritional density. Among them, in the first three months, the low-carbohydrate mode was adopted, that is, rice flour and other high-starch foods were restricted. In order to reduce hunger, meal replacement powder was used together. After three months, the success rate of weight loss was 60.0%, which produced obvious early weight loss effect.

　　"Whether it is psychological or substantive, from the clinical observation, the role of meal replacement in weight loss is indeed not small." Deng Yuhong further explained that first of all, meal replacement has a sense of ritual, reminding himself that "now I am losing weight and can’t eat more". Secondly, increase satiety and reduce appetite. Meal replacement powder generally adds konjac flour, whey protein powder, soybean protein powder, dietary fiber, etc. Of course, some fats and carbohydrates provide basic calories, which can fight hunger after eating.

　　Reminder:

　　Long-term blind eating meal replacement has side effects

　　It is worth mentioning that this study tried to follow up patients after one year, but the loss rate was too high. It is pointed out that the patient’s withdrawal may reflect the patient’s intolerance to this dietary pattern. Deng Yuhong also said that in fact, in the actual research, the loss rate of weight loss projects has been high, ranging from 15% to 50%.

　　Deng Yuhong said that the ordinary balanced diet pattern is the long-term eating habit of Chinese people. Once it changes, such as reducing staple food, it begins to try "half-generation meal" (instead of one meal) or even "full-generation meal" (instead of all meals). The stronger the degree of intolerance, the weaker the execution, because people are born to pursue diversified diets and everyone’s physical condition is different, but the weight loss gimmicks of businesses are often "simple and rude".

　　"For example, there used to be a company that made meal replacement food, which required that every meal must be meal replacement, only 700 calories a day, and it must be eaten for a month, which of course would be thin. But the problem is that most people will fall into ‘ Yo-yo ’ Effect, eating meal replacement, the overall intake of calories is less, and the weight is down; Stopped the meal replacement and gained weight again. The harm caused by the rebound is self-evident. "

　　Doctors remind that the cost of educating the masses is often high, especially it takes time and energy to let everyone know about the dangers of obesity and popularize how to eat a balanced and healthy diet. However, many businesses often skip this step. In order to maximize profits, they often take advantage of people’s weakness of wanting to lose weight in the short term and publicize the effectiveness of weight loss products. They need to be more vigilant and do not recommend sacrificing health. After all, many meal replacement products have very few calories, and there are many side effects in the long run, especially women are prone to endocrine disorders and anorexia.

　　Doctors suggest that ordinary people can check whether they are really obese by calculating BMI and going to the hospital for physical examination, ignoring this step and blindly losing weight with the wind, thus damaging their own metabolic rate, which may have been superior, but it is not worth the candle.

According to the data provided by Guangxi Border Inspection Station, during the May 1 holiday in 2024, there will be more than 196,000 inbound and outbound passengers at Nanning, Youyiguan and Dongxing ports.

May 1 — On the 5th, Nanning Port plans to have about 44 direct flights to 12 cities, including Hong Kong, Macau, Manila, Philippines and Phnom Penh, Cambodia. It is predicted that the number of inbound and outbound passengers will exceed 11,000.

Friendship Pass in Pingxiang, Guangxi is one of the most convenient land routes from China to Vietnam. Its unique border customs and scenic spots in Hongguan attract many Chinese and foreign cross-border tourists. During the "May Day" holiday, it is estimated that the number of inbound and outbound passengers at Youyiguan Port will exceed 45,000, and the daily average is expected to be close to 10,000 during the peak period.

As the largest land port on the border between China and Myanmar, Ruili Port plays an important role as a bridge and link in the trade between China and Myanmar. The data shows that compared with the fourth quarter of 2023, in the first quarter of 2024, the inbound and outbound passenger flow at Ruili Port increased by 9.1% month-on-month, and the inbound and outbound means of transport increased by 1.6% month-on-month, and the average daily inbound and outbound passenger flow exceeded 12,000.

Hekou Port is the largest land port in Yunnan section of Sino-Vietnamese area. It is estimated that the number of people entering and leaving the country will exceed 70,000 during the May Day holiday in 2024.

　　Implementation of Ten Key Livelihood Facts in Henan Province in 2019 (III)

　　The task of free "two cancers" and "two screens" was overfulfilled.

　　"In 2019, the province completed 1,448,500 free screening for cervical cancer and 1,487,200 free screening for breast cancer; 698,500 cases of free prenatal ultrasound screening and 777,000 cases of free serological screening were completed; There were 1,141,000 cases of neonatal’ two diseases’ screening and 1,123,900 cases of hearing screening, all of which exceeded the target. " On January 4th, a set of data released by Cui Ailan, member of the Working Committee of Women and Children of the Provincial Government and vice chairman of the Provincial Women’s Federation, was very warm at the third press conference of "Implementation of Key Livelihood Facts in 2019" held by the Information Office of the Provincial Government.

　　fact

　　In 2019, our province listed "continuing to carry out cervical cancer and breast cancer screening for women free of charge, prenatal screening for preventing birth defects and screening for neonatal diseases" as a key livelihood fact, and required to continue to carry out cervical cancer and breast cancer screening for rural school-age women and school-age women included in the urban minimum living allowance free of charge, and completed screening for 1.4 million people in 2019; Continue to carry out free prenatal screening to prevent birth defects and neonatal diseases, and provide free prenatal diagnosis for high-risk pregnant women who have been screened.

　　trace

　　Maternal and child health is an important foundation of national health, which concerns the happiness of thousands of families. In 2019, for the third year in a row, the provincial party committee and the provincial government listed the improvement of women’s and children’s health security as a key livelihood issue, and sent a warm-hearted "gift package" to the majority of women and children in the province.

　　Cui Ailan introduced that in the past year, the Provincial Women’s Federation, together with the Provincial Health and Wellness Commission, the Provincial Department of Finance, the Provincial Civil Affairs Department and other relevant responsible units, carefully organized and paid close attention to implementation to ensure the improvement of women’s and children’s health protection and the orderly advancement of people’s livelihood. The provincial finance at all levels has allocated a total of 858 million yuan to provide a strong financial guarantee for the smooth implementation of people’s livelihood.

　　The objectives and tasks were overfulfilled. By December 31, 2019, the province had completed 1,448,500 free screenings for cervical cancer and 1,487,200 free screenings for breast cancer, exceeding the annual target. The province completed 698,500 cases of free prenatal ultrasound screening and 777,000 cases of free serological screening, and the coverage rate of prenatal screening for pregnant women in the early and middle stages was 65.82%, exceeding the target requirement by 15.82 percentage points; There were 1,141,000 cases of neonatal "two diseases" screening, and the screening rate was 96.64%, which exceeded the target requirement by 6.64 percentage points. There were 1,123,900 cases of newborn hearing screening, with a screening rate of 95.2%, exceeding the target requirement by 5.2 percentage points. The provincial cities and counties (cities) directly under the jurisdiction of the province have exceeded the provincial targets.

　　Free screening has achieved remarkable results. In 2019, through the free "two cancers" screening, 585 cases of breast cancer, 24 cases of precancerous lesions and 3,674 cases of benign lesions were diagnosed in the province, and 501 cases of cervical cancer and 4,093 cases of precancerous lesions were diagnosed; Through free prenatal ultrasound screening, 6816 high-risk pregnant women were found, and 44618 high-risk pregnant women were found in prenatal serological screening. Through the screening of neonatal "two diseases", 129 cases of phenylketonuria (PKU) and 862 cases of hypothyroidism (CH) were diagnosed in the whole province. Through newborn hearing screening and further diagnosis, 1159 children with congenital hearing impairment were diagnosed. These patients and children have received timely and standardized referral treatment and follow-up services.

　　In view of the sick women screened for "two cancers", our province has also taken a series of measures to help them further get standardized treatment. It is understood that cervical cancer and breast cancer are included in the scope of serious and serious diseases in the province, and sick women can not only enjoy basic medical insurance, but also enjoy serious illness medical insurance. The Provincial Women’s Federation has won a total of 142.11 million yuan for national and provincial "two cancers" relief funds, and rescued 14,211 poor women suffering from cancer.

　　Cui Ailan said that through the implementation of this livelihood, the people’s sense of gain has been enhanced; Women’s health awareness has increased, and many women have changed from "I want to check" to "I want to check"; The awareness of diagnosis and treatment of high-risk groups has improved, and the concept of early detection, early diagnosis and early treatment has become more deeply rooted in the hearts of the people. "We will do a good job in people’s livelihood with a more pragmatic style and more effective measures, be a good’ family’ and send the warmth of the party and the government to thousands of households." (Henan Daily reporter Wang Lvyang)

Affected by the epidemic, the development of foreign trade is facing great challenges. While continuing to explore the international market, many foreign trade enterprises are generally optimistic about the potential of the domestic market and begin to put marketable export products into the domestic market.

Recently, the reporter walked into the park of Ganzhou Aoketai Tool Technology Co., Ltd., and saw that the blades in the workshop were neatly arranged on the production line, and the processes of mold calibration, surface grinding, coating and polishing were orderly. After customs inspection, these products can be packed and shipped to the domestic market for sale.

Aoketai Company is one of the fast-developing precision metal tool manufacturers in China and one of the major tool export enterprises in Jiangxi. Besides domestic sales, products are also exported to Spain, Germany, Poland and other countries.

"Affected by the epidemic, the sales of our products in the European and American markets have been greatly impacted. At the same time, domestic tool importers have turned to domestic tools in the context of the domestic cycle. We want to take this opportunity to make the domestic market bigger and stronger and stabilize production and operation." The person in charge of the enterprise said, "Comrades from the Customs took the initiative to come to our door, explained the technical and trade policies to us, instructed us to produce products of the same line, the same standard and the same quality that can be exported and sold domestically, and also preached the policies related to tax reduction and exemption, and taught us how to prepare the application materials, which helped us save a lot of money. With such a’ family’, we are full of confidence and expectation for the future development. "

In order to promote the development of emerging industries and high-tech industries in southern Jiangxi Soviet area, Ganzhou Customs, a subsidiary of Nanchang Customs, has tailored a number of assistance measures in combination with industrial characteristics, and constantly explored the supervision service mode of high-tech products with southern Jiangxi characteristics. With the "100 million" service plan as the starting point, publicize policies such as customs protection of intellectual property rights and technical trade measures through interviews, surveys and special lectures; Continue to publicize the preferential policies of RCEP FTA, vigorously promote and promote the "smart audit+self-printing" smart examination and approval mode of certificate of origin, improve the efficiency of tax reduction and exemption approval, and help enterprises fully enjoy the tariff dividend of FTA; The establishment of an enterprise-related coordinator provides policy advice and professional guidance for enterprises in key parks, strengthens the daily supervision of enterprises, constantly regulates the production and processing processes of enterprises, and ensures product quality.

According to the statistics of Ganzhou Customs, from January to April this year, the total import and export value of high-tech products in Ganzhou was 3.58 billion yuan, accounting for 22% of the city’s total export value in the same period, up 18.5% year-on-year.

　　【Minsheng investigation bureau】

　　Editor’s note:

　　This is the People’s Livelihood Investigation Bureau, which has never been seen before, investigating the changes in people’s livelihood. Pay attention to what you want to pay attention to and what you don’t, and investigate what you want to see and what you don’t see.

　　Chinanews. com client Beijing, April 10 th:If you can’t flirt, you will be fooled: can you fight harassing calls?

　　Reporter Wu Tao

　　"Do you need to buy a house?" "What about unsecured loans?" "How about stock investment recently?"

　　This year’s CCTV 3.15 party exposed the madness of harassing calls. Has the situation of harassing calls improved now? The reporter’s investigation found that there are still people who are "committing crimes" against the wind, and some users have reported that the number of harassing calls has increased significantly recently.

　　"My phone number is rotten on the street."

　　Gao Ning (pseudonym) left personal information such as telephone number in a real estate in Qinhuangdao in 2016. From then on, he will receive a phone call to ask if he wants to buy a house, which has continued until now.

　　"The key is not only this property, but also several properties have been called to me. I suspect that my phone number has been ruined in the Qinhuangdao real estate agency circle." Gao Ning said.

　　There are many people like Gao Ning. Recently, some users told reporters that although the 3.15 party exposed the rampant situation of harassing calls, the frequency of receiving harassing calls has not dropped significantly recently. He counted the harassing calls he received in the past month, about six, and received one every five days on average.

　　The point is, it takes no effort or time for people to harass you. "I often get harassing calls, and I am so angry that I once wanted to flirt with the harassing phone and talk nonsense with it for 5 minutes. Recently, I learned that harassing calls can be used for robot chat, and I think of this matter as angry and funny. " The above users said.

　　Because software and labor are different, the efficiency is very high, even if it is not aimed at fixed user groups, the cost is not high. A company official said that they made more than 4 billion harassing calls a year.

　　A software marketer said that taking making 2000 calls as an example, the efficiency of their software is 6-8 times that of normal manual work.

　　According to the first telecom service quality notice of the Ministry of Industry and Information Technology in 2019, in the fourth quarter of 2018, the 12321 report acceptance center accepted 230,694 complaints and reports from users about harassing calls, down 5.1% from the previous month. Although the number of complaints and reports declined, it was still at a historical high.

　　Want to call back and scold after being harassed? "Call failed"

　　The reporter noticed that the current harassing phone technology has been upgraded rapidly. For example, everyone has the impression that there are more harassing calls at 400 and 800, and now many of them start with 95 and 96.

　　The reporter experimented that users can only passively accept harassing calls at the beginning of 95, even if they call back, and the call back shows "Call Failed".

　　Some harassing calls are more confusing and look just like ordinary numbers. It is understood that this may be because the harassing phone used the technology of virtual calling and changed the calling number in order to gain the trust of users.

　　In March, the Ministry of Industry and Information Technology issued a message to strictly investigate the violations of virtual calling numbers using transparent transmission technology, and intercept all calls that failed authentication.

　　Who is "boosting" harassing calls?

　　Like "no business, no harm", the rampancy of harassing calls cannot be separated from the "assistance" of some enterprises.

　　A few days ago, Beijing Communications Administration focused on Baidu, Qihoo 360, sogou and other search service providers in response to the harassment of telephone software sales promotion information found on the Internet, and asked the three companies to rectify. All three companies said that they would thoroughly investigate the problems and immediately rectify them.

　　Afterwards, the reporter from Zhongxin. com consulted the public relations staff of a search engine company mentioned above, and the other party looked "stunned". "Huh? Have we been interviewed? " It is conceivable that enterprises do not attach importance to this matter.

　　Recently, reporters searched for keywords such as "telephone software" and "telemarketing", and there are still related softwares doing search promotion. There are many softwares that support robot marketing, autonomous speech configuration and human-computer interaction.

　　The Ministry of Industry and Information Technology has clearly stipulated that all Internet companies should comprehensively clean up the information of harassing software and equipment such as "calling you to death" on the Internet, and cut off the promotion, sales and use channels of related software and hardware.

　　Some marketing robots on e-commerce only sell 400 yuan for one year.

　　More seriously, it’s not just search engines. The influence of harassing telephone software has penetrated into many fields such as e-commerce and social interaction.

　　Reporters lurked in QQ groups selling several telephone software and found that people kept sending out advertisements to make outbound calls. Moreover, according to the description, the software was very powerful, and intelligent robots, screen-blocking short messages, and all invalid numbers such as shutdown and empty numbers could be automatically filtered out.

　　On the idle fish of the second-hand trading platform, there are also marketing robots for sale, which can be called out in batches, and the robot simulates customer service. And the price is very cheap, 400 yuan every year.

　　This year’s 3.15 party also revealed that some enterprises are selling probe boxes, which can collect personal information such as users’ phone numbers when placed in crowded places such as Shangchao. Among these enterprises, there are many listed companies with strong technical and financial strength.

　　Why is it difficult to eliminate?

　　Some insiders told the reporter of Zhongxin. com that the reasons why harassing calls are difficult to eliminate are very complicated, including difficulties in implementation and serious information leakage.

　　"Take the source of the harassed phone number as an example. It turns out that Internet companies are often exposed to information leakage, and Internet companies say ‘ Hit the library, reported ’ It’s over, but there is endless thunder: these numbers will be repeatedly bought and sold, and even classified and sold to different marketing companies. "

　　Even if there is no number resource, harassing calls can still be made. The reporter also noticed that some telemarketing software claimed that "without customer resources, the system will be automatically generated."

　　Operators may also be responsible for harassing calls. In November 2018, the notice issued by the General Office of the Ministry of Industry and Information Technology on the "Work Plan for Promoting the Special Action of Comprehensive Remediation of Harassment Calls" showed that all basic telecommunications enterprises and mobile resale enterprises should provide domestic mobile phone users with the reminding of the number of suspected harassing calls and the ability to prevent and control risks. And marked to be completed before the end of March 2019.

　　Thirteen departments, including the Ministry of Industry and Information Technology, have also asked all basic telecommunications enterprises to strictly examine the user qualifications of voice lines and code number resources such as 95, 96 and 400 in accordance with the principle of "whoever accesses them is responsible" and standardize the use of resources.

　　However, some users have reported that the harassing calls received at present are rarely marked. Although they see strange numbers, they will still answer them for fear of missing important calls. "Some numbers starting with 95 will also change the tail number to call you. The actual promotion is one thing, and it is impossible to prevent it."

　　Some insiders of the operator told the reporter of Zhongxin.com, "The key is that it is impossible to judge what is a harassing phone call. For example, a phone call to sell a house is harassing for those who have no need to buy a house, but it is just needed for those who urgently need to buy a house."

　　From this point of view, there is still a long way to go to rectify harassing calls. (End)

With a pink nose, small eyes, wide and flexible ears and a broom-like tail, the pig-tailed mouse, known as the "blind mouse", has an echolocation ability.

Recently, researchers from Kunming Institute of Zoology, Chinese Academy of Sciences came to this conclusion.

The research groups of Shi Peng, Jiang Xuelong and Liu Zhen, the State Key Laboratory of Genetic Resources and Evolution of the Institute, jointly tackled the problem, and confirmed that the species of the genus Rodent has the ability of echolocation by integrating several independent evidences of ethology, anatomy, genomics and gene function experiments.

"In addition to the well-known bats, toothed whales, etc., pigtail rats also have this ability, which is amazing in itself!" On July 5th, one of the researchers, Dr. Liu Qi from Shi Peng’s research group, was interviewed by The Paper (www.thepaper.cn) and introduced that the research on echolocation ability of pigtail rats lasted for about 4 years. This study is expected to make the pig-tailed rat become a new experimental animal to study the neural circuits of sound, hearing and echolocation. He also hopes that the research results can be applied to artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.

"Are there other mammals that have this ability but have not been discovered?" Liu Qi believes that there is still a lot of room for the research and application of echolocation, and the research on pig-tailed mice is only the beginning.

The experiment lasted for nearly four years, and the researchers stayed up late with the pig-tailed rats.

The nose is pink, the eyes are small, the ears are wide and very flexible, just like bats, they will swing back and forth and collect sounds in different directions. Its tail is very long, shaped like a broom, and there is a pinch of white hair at the end of it.

This is Liu Qi’s research object-pigtail rat, which is also called "blind rat" because of its small eyes. It belongs to the genus pigtail rat of Rodent Echinopodidae.

Liu Qi studied the echolocation ability of pig-tailed rats. Echo location refers to a directional behavior of animals in navigation, foraging and other activities by comparing the information difference between sending sound waves and receiving echoes.

As early as 2017, Liu Qi had already started this research.

At that time, after he did some basic work, the experiment had preliminary research results. He organized the experimental content into an English manuscript and sent it to secience magazine in the form of a short article. Journals have given great affirmation to this research achievement and shown great interest, which has given them great confidence.

"In the later process, we supplemented many experiments according to the requirements of the magazine and constantly enriched and improved the paper." Liu Qi said that on the one hand, it is necessary to obtain accurate experimental evidence from many aspects, on the other hand, the workload of each experiment is very large, including the subsequent papers being revised many times, so the whole project involves a long time, and it is a joint effort of multiple research teams.

Liu Qi introduced that the correspondence authors Shi Peng and Liu Zhen’s research group have been engaged in the research on the convergent evolution and molecular genetic mechanism of echo localization for a long time, and have published many heavyweight research results. Another cooperative team, researcher Jiang Xuelong, who is also the correspondent of the paper, is engaged in the research on the behavioral ecology, phylogeny and classification of pig-tailed rats. This research is the result of joint research by three research groups.

Although there are three top teams in the joint experiment, there are many difficulties in the experiment.

Liu Qi introduced that the first difficulty comes from the research object-the pig-tailed rat. Before the study, they didn’t know much about the living habits of this kind of wild animal, such as what it eats, where it lives, whether it lives in groups, what its nest looks like and its activity time.

Secondly, the wild population of pigtail rat is not large, so it is a big problem to catch it and catch a certain number of live pigtail rats when doing experiments with it.

At the same time, the researchers have no experience in raising pigs. After catching a certain number of pigs, they don’t know how to raise them. They are worried that the artificially created conditions can’t make pigs behave naturally.

However, with the advancement of the experiment, solutions have been found to these difficulties.

What makes Liu Qi feel very interesting is that in the experiment, they found that animals such as pigtail rats are nocturnal. They sleep during the day and are more active at night. Therefore, in the process of behavioral experiments, researchers arrange experiments at night, and sometimes they have to work all night to complete an experiment.

The echolocation function of small-eyed "blind mouse"

Liu Qi said that in the experiment, they recorded the short-term, frequency-modulated and high-frequency sound waves (peak frequency ~98 kHz) regularly emitted by the pig-tailed rats during movement. In dark environment, pigtail rats will emit higher ultrasonic velocity in complex space environment and when avoiding obstacles. All these results show that the ultrasonic waves emitted by pigtail rats play a directional role in sports behavior, that is, echolocation.

Subsequently, the researchers used classic experimental devices and strict experimental design to verify whether the pigtail mouse has the ability of echolocation. Through the behavioral task experiment, it is found that the pigtail rats will spend more time and send out higher ultrasonic speed to explore the target. They can accurately detect the escape platform and successfully obtain food rewards in complete darkness. When its ears are blocked, the pig-tailed rat can’t receive the echo and can’t detect the target and complete the task; After removing the earplugs, the pig-tailed rat recovered its ability to explore and locate the target. Under the condition of eliminating vision, touch and controlling sense of smell, behavioral experiments confirmed that the pigtail mouse achieved its goal by emitting ultrasonic waves and receiving echoes by hearing.

In addition, the researchers used technical means to present the anatomical structure of the pig-tailed rat, and found that the spatial position of its hyoid bone and tympanic bone contacted and fused, which was consistent with the structure of the echolocation bat that sounded through the throat. This shows that the pig-tailed rat and the echolocation bat with laryngeal vocalization have the same anatomical structure basis in vocalization and auditory structure.

Liu Qi and other researchers also sequenced and assembled the high-quality whole genome of the Chinese pigtail mouse. Through evolutionary genomics analysis, it was found that the echolocation of the pigtail mouse originated independently. In the whole genome, the pig-tailed rat and the known echolocation species (bats and toothed whales) are significantly enriched in auditory genes.

By integrating several independent evidences of ethology, anatomy, genomics and gene function experiments, it is confirmed that the species of the genus Rodentia has the ability of echolocation.

It is expected to be used in artificial intelligence, blind-assisted navigation and other fields.

The echolocation ability of pigtailed rats seems to be inferior to that of ordinary people. However, Liu Qi said that this research may be applied to artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.

Liu Qi said that from the perspective of science itself, echolocation, as a special behavior of animals, is very rare in the animal kingdom. At present, the echolocation species known by human beings may be limited to a few kinds, such as bats and toothed whales, which are familiar to everyone, and some unfamiliar ones, such as some birds, shrews and hedgehogs.

"In addition to the animals listed above, we have confirmed that there is another kind of mouse, which also has echolocation skills. It is amazing in itself to find food or locate targets by hearing and ultrasound!" Liu Qi said that in addition to five groups of independent origin, such as bats, toothed whales and giant whales, the research team found a sixth group with this ability.

In addition, because the pig-tailed rat is a rodent, its genetic relationship and size are close to those of model animal mice, and its breeding is easy to operate, it is expected to become a new experimental animal to study the neural circuits of sound, hearing and echolocation.

Liu Qi said that human beings have developed many bionic products based on the long-term research on echolocation species such as bats. For example, bats will send out ultrasonic waves to detect targets, track moving prey, or avoid obstacles in time. The invented guide rod is convenient for the blind to move.

He admits that there is still a lot of room for the research and application of echolocation, and the research on bats, pigtails and other animals and their echolocation will have more influence on human life in the future.

After discovering that pigtail rats have echolocation ability, Liu Qi and his research team have been thinking about whether there are other nearly 6,000 kinds of mammals in nature that have this ability but have not been discovered. They hope that through the efforts of the team, they can find more such magical animals.

"This requires the unremitting efforts of many researchers, and it may even be a very long exploration process." Liu Qi said that the discovery of pig-tailed rat and its echolocation is only the beginning. They hope to stick to this research and expect that it can be used in artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.
