Cctv newsOn May 17th, with the statements of the three basic operators, Beijing began to enter the era of "100 Mbps broadband". However, some users are still using the old copper broadband, with a slow speed of 4 megabytes and 5 megabytes. However, some users who have installed 20 megabits, 50 megabits or even 100 megabits of fiber-optic broadband at home often have delays in playing online games, and sometimes even ordinary web pages are difficult to open. What stuck the "last mile" in fttp? What caused the "short weight" of broadband speed increase? Come to see the reporter’s investigation.

　　Once "insulated" optical fiber in high-grade residential areas

　　Mr. Pan in Beijing lives in a relatively high-end residential area in the North Fourth Ring Road. The apartment building has its own independent system, and electricity, tap water, gas and communication are all self-contained and provided by the property management. Therefore, the annual fee of broadband used by Mr. Pan is more expensive than that of basic operators, but the broadband rate is only 5 trillion.

　　"I want to open the website and watch a video news." Mr. Pan, who hopes to have a faster network speed, went to the business halls of China Unicom, China Telecom and China Mobile to apply for registration, but was told that the residential area was not covered with optical fiber because the apartment was not allowed to enter.

　　A similar situation is not uncommon in other communities. In some communities, there is only one broadband service provider to choose from, and even the advertisements of other broadband companies are hard to see. However, the only broadband service provider is often slow and expensive. Mr. Pan wondered that the optical fiber had been laid at the bottom of the residential building, but it was stuck because of this "last mile". Who will protect the rights of the residents?

　　100 Mbps broadband WeChat voice chat will be dropped.

　　"When we register our children online, we are particularly anxious. A fairly simple webpage can’t be opened." Mr. Hong, a citizen, uses the 50-megabit-rate fiber-optic broadband annual service handled by Great Wall Broadband at home. However, after using it for one year, Mr. Hong felt that this 50-megabyte bandwidth was more like an "embroidered pillow".

　　Mr. Jiang has just moved to a new home this year. Last month, he installed 20 megabits of "Dr. Peng" broadband, and the annual subscription fee was 1180 yuan. He said that he originally wanted to install the broadband of a big telecom operator, but the reply he got was that the community was not covered yet, so he could not go to fttp. "The network speed is very unstable. Now our community has only occupied about 40% of users, and playing an online game will get stuck. What if everyone moves in? " Mr. Jiang is deeply anxious about this.

　　Mr. Wang, who lives in Yizhuang, said that the 100-megabit fiber-optic broadband in his own community would suddenly fail to open ordinary web pages, or be inexplicably disconnected while playing games, and there have also been cases where voice chat on WeChat suddenly broke. Mr. Wang showed several times the value of online speed measurement. In the case of using the telecom speed measurement web page, the fastest time, the tested bandwidth was only 26 megabits, which was only a quarter of the 100 megabits rate.

　　remove a doubt

　　Obstruct operators from entering the market for the benefit of property.

　　According to Beijing’s informatization development plan, the free transformation of "light entering copper retreating" has been started in the whole city since 2011. Up to now, most of Beijing’s urban residential areas and rural areas have realized optical fiber to the building or fttp. However, there are still a few residential areas that can’t go home for "optical reform" for various reasons.

　　According to an operator, some residents are unwilling to carry out optical fiber transformation in the residential areas that cannot be "light-reformed" at present, but more because property companies or property rights units obstruct operators from entering the market. "Of course, the reason for obstruction is for the benefit." According to a person familiar with the matter, in addition to admission fees, some property companies are not satisfied with collecting money at one time, and put forward new requirements such as broadband revenue sharing and collecting maintenance fees every year.

　　In this regard, in 2016, the three departments of Beijing jointly issued the Notice on Promoting the Implementation of residential broadband Access for Property Management. It stipulates that real estate development enterprises or property service enterprises shall not sign monopoly or exclusive broadband operation agreements with others. On the premise that the infrastructure such as the equipment room has multiple accesses, the realty service enterprise shall try its best to meet the needs of the owners, at least ensure that more than three broadband operators have equal access, and disclose the relevant information of broadband access to the owners in a prominent position in the community.

　　Too many users will lead to insufficient bandwidth.

　　"The bandwidth mentioned by telecom operators is all theoretical values." A telecom expert said that in actual use, the download speed is lower than the theoretical value. Generally speaking, fluctuations in the range of 75% to 90% of the theoretical value can be regarded as normal. There are two main reasons why home users often feel that the network speed is not up to standard: the hardware facilities are not matched, or there are too many sharing users.

　　Experts explained that in order to make full use of broadband resources, increase broadband revenue and reduce costs, operators will calculate an online ratio and choose how many users to configure on this basis. "In order to seize more business, small operators often attract customers at very low prices, and then configure more users regardless of the online ratio, resulting in insufficient broadband."

　　Lack of authoritative third-party speed measuring mechanism

　　How do you know how much "moisture" is mixed in the rate of home broadband? Just like Mr. Wang, a citizen, in practice, many users will choose to use speed measuring software to measure speed. However, the third-party speed measuring software on the network, not only the speed measured by each speed measuring software is different, but also the same software often measures different speeds.

　　 The Ministry of Industry and Information Technology has said that the local communication administrations will cooperate with third parties to measure the speed of "fixed broadband access rate" and release it to the public. But up to now, there is no authoritative third-party broadband speed measuring agency in China.

　　CCTV News:Pretending to be an acquaintance to borrow money, pretending to be a public security bureau, a procuratorate or a court officer to investigate a case, and hiding a Trojan link &hellip in short messages and QR codes; … These tricks must have made everyone immune, but do you know? Some telecommunications services that you have never heard of have also begun to become new traps set by scammers!

The mobile phone was locked and more than 50,000 yuan was stolen.

　　When he woke up, Mr. He in Shenzhen found that his mobile phone was locked. At the same time, a shopping platform account was stolen by strangers. Criminals used white bars to spend and apply for loans, and robbed more than 50,000 yuan overnight.

　　Later, Mr. He discovered that his mobile phone had been taken over by a strange number. The short message from the operator shows that this is a business to add a secondary number, and Mr. He’s mobile phone number was added as a secondary number by criminals. When the secondary phone is turned off, all short messages will be received by the primary phone, and criminals will receive Mr. He’s short message verification code during this period, and then commit crimes.

"Subnumber" ≠ "kinship number"

　　Without an ID card, a bank card or even a real name, the money is gone. What the hell is a minor number?

　　Many people think of "family number" at first, but "deputy number" and "family number" are not the same thing.

　　Family number usually refers to the phone bill package opened by different owners and different numbers in order to make calls between them cheaper, and the secondary number is the "one card with many numbers" service provided by operators. On the basis of not changing mobile phones and SIM cards, users can add up to three real mobile phones as secondary numbers. The main and auxiliary numbers can stand by at the same time, and you can freely choose any number to dial, answer the phone and send and receive short messages as needed.

Don’t reply to text messages too casually.

　　Then, how did Mr. He’s mobile phone number become the "secondary number" of criminals?

　　Reduction of criminal modus operandi

　　Step 1: Buy materials.Criminals buy leaked names, bank card numbers, ID numbers and reserved mobile phone numbers online, commonly known as "four big pieces".

　　Step 2: Fishing.Criminals apply to the users who have mastered the bank card information, initiate the business application of binding the sub-number, and find the target of the crime by casting a net widely. Once you reply by mistake, you are hooked.

　　Step 3: Forced shutdown.Because the main number can only take over the SMS when the secondary number is turned off, criminals usually use two means at this time. One is to use SMS bombing to force the target to turn off the mobile phone, and the other is to use the mobile phone cloud service to remotely operate the mobile phone.

　　Step 4: White Wolf with Empty Gloves.Using the SMS verification code received by the main number, criminals ransacked the online shopping account bound to the mobile phone number.

　　Patterns are stacked, and it is impossible to prevent them! For this kind of fraud, after receiving all kinds of SMS notifications, you must read the content of the SMS clearly and do not reply at will.

"SMS custody" business is also not very secure.

　　After the SMS storage service is opened, you can save your mobile phone messages on the server of the operator. Now, many mobile phone manufacturers’ cloud services are doing the same thing. However, this is a hidden danger function.

　　Case review

　　One morning, Miss Ding saw two short messages from banks and mobile phone operators on her mobile phone, which were sent at 3:43 am and 4:12 am respectively. As soon as the account is checked, the balance of more than 100,000 yuan will be zero overnight! Not only that, Miss Ding also suffered a credit card theft and was "applied" for a bank universal loan of 70,000 yuan.

　　How on earth did all this happen?

　　Reduction of criminal modus operandi

　　Step 1: Hit the database to get all kinds of account information.The so-called "library collision" means using software to try a high probability digital sequence. Using this simple and rude method, the user’s network identity, online banking account number, mobile phone business hall and other accounts can be seen at a glance. Insiders said: "The speed of library collision is very fast, at least thousands per minute. If some good equipment is used, the efficiency is higher and the success rate is above 50%."

　　Step 2: Open SMS storage and SMS interception services to obtain verification code.This is the most critical step. After the opening of this service, the dynamic verification code to ensure the safety of landing has successfully become the bag of criminals.

　　Step 3: Open the physical SIM card.At this point, criminals can pretend to be victims and apply for 4G card replacement service in the online business hall. For the convenience of the people, some operators can express the card directly to the designated address.

　　By intercepting short messages and copying SIM cards, fraudsters can "do whatever they want".

　　As we all know, many important services rely on mobile phone authentication. If you back up the SMS to the server synchronously, it will increase the exposure opportunity. Once the service password of the online business hall is stolen, or the login permission of the cloud service is stolen, it is equivalent to "swimming naked".

The loopholes in the unpopular business are targeted by scammers.

　　The "Research Report on the Trend of Online Fraud in 2016" released by the anti-fraud reporting platform "Hunting Network Platform" proposes that since 2016, online fraud has mainly shown several obvious characteristics:

　　Mobile phone cards have become new theft targets;

　　Jump to the phishing website by using short URL and weiyun sharing link;

　　Well-known recruitment websites and voice platforms for open recruitment;

　　A phishing website that is difficult to distinguish between true and false;

　　The implementation of precision fraud;

　　Fraud professionalism is getting higher and higher;

　　Using loopholes in new business and unpopular business to commit fraud;

　　Use cloud disk and synchronization software to steal information.

　　Among them, the loopholes in mobile phone cards and unpopular business are mentioned.

　　Security experts suggest that we should develop good online habits, don’t click unfamiliar links, don’t fill in our personal information in the website interface with unknown security, and regularly modify the password of social accounts to avoid information such as mobile phone contact information being leaked; Improve safety awareness, develop good habits of using mobile phones, and avoid being infected by mobile phone viruses.

　　Beauty cosmetics guide to avoiding pits

　　Reporter Jin Feng

　　If you want something beautiful, how can you do it without skin care and makeup? In the eyes of many beauty experts, today’s skin care and makeup process is not just as simple as "washing your face and applying a cream", but involves a series of steps such as cleansing, toner, cream and essence.

　　Before these operations, the quality of the product is the most important thing. In order to identify the quality of the product, there are various methods circulating on the Internet: "Facial cleanser is baked with fire, and if it is splashed with oil or baked more and more like yogurt, the safety factor is not high." "Shake toner, if there is less foam, it means less nutrients." "Put salt on lipstick and rub it. If there are black particles, it means that the content of lead and mercury exceeds the standard, never buy it. … Can these seemingly simple "earthworks" help us polish our eyes, and how can we choose the products that suit us?

　　Improper operation: baking facial cleanser with fire and spilling oil are not safe.

　　Positive solution: oil spills are caused by oily components or emulsifiers.

　　"Roasting with fire will spill oil, or the more it is roasted, the more it looks like yogurt, which does not explain the quality of facial cleanser." Chi Bo, a professor at the School of Food and Light Industry of Nanjing University of Technology and the State Key Laboratory of Material Chemical Engineering, told the Science and Technology Daily reporter that splashing oil when baking facial cleanser with fire can only prove that there are oily ingredients or emulsifiers in facial cleanser.

　　Chi Bo said that some facial cleansers with strong cleaning power and more soap-based surfactants will add some grease or emulsifier. Grease can reduce the degreasing power of soap-based surfactants and make facial cleansers softer to use. This facial cleanser will spill oil if baked with fire, but it does not mean that it is unsafe to use this facial cleanser.

　　As for why facial cleanser is baked more and more like yogurt, it is related to the formula of facial cleanser. Chi Bo said that some facial cleansers have high fineness, and the water evaporates after baking, and the molecular structure of the emulsifier has not been destroyed, so it will be very sticky, but this can only prove that its emulsification system is relatively stable and the facial cleanser will be stored for a relatively long time.

　　Since the method of identifying the quality of facial cleanser by fire roasting is not reliable, how to judge the efficacy of facial cleanser? "After using a good facial cleanser, the face is not tight." Chi Bo said, "In particular, it is not recommended for people with sensitive skin to use facial cleanser that makes the skin feel tight, because it will remove the oil that acts as a barrier on the skin surface."

　　Xu Yang, deputy chief physician of jiangsu province hospital Dermatology Department, also said that the main function of facial cleanser is cleaning. After cleansing, the skin is not tight, moist and dehydrated. If you want to moisturize the skin, you might as well use facial cleanser containing moisturizing ingredients such as glycerin and allantoin.

　　In addition, the pH value of facial cleanser is preferably weakly acidic. "The pH value of skin is about 4.1— 5.8, and the pH value on the market is 6-mdash; Facial cleanser between 7 can be used, and the pH value can be measured with test paper. Although the degreasing of alkaline or soap-based facial cleanser is better, if it is too alkaline, it may affect the pH value of the skin. " Xu Yang said that after the change of skin pH value, it will cause changes in skin flora. If the pH value increases, it will form an environment conducive to the growth of some skin bacteria such as propionibacterium acnes, thus increasing the probability of acne on the skin.

　　Chi Bo suggested that for people with oily skin, you can use soap-based facial cleanser containing dodecyl and laurate, but you should also beware of excessive cleaning and damage to skin oil. Excessive cleaning will make the skin dry and tight, and it will also open the pores completely, which will increase the chance of contact with germs and lead to skin allergies. People with neutral and sensitive skin are more suitable for facial cleanser containing amino acids and olive oil lipids.

　　Inclined operation: shake the toner, and there are many nutrients in the foam.

　　Positive solution: the content of surfactant determines the amount of foam

　　After washing your face, especially in hot summer, pat a little toner on your face, and a refreshing feeling will come to your face. So how to identify the advantages and disadvantages of toner? Some netizens suggested shaking the toner. If there is less foam, it means less nutrients. Is that true?

　　"The content of nutrients has nothing to do with the amount of foam." For this method circulating on the Internet, Chi Bo said that many ingredients in the toner will not produce foam, such as vitamin C, plant extract, salicylic acid and so on.

　　Xu Yang said that the ingredients in toner are both water-soluble and fat-soluble, such as hyaluronic acid and fruit acid, which are water-soluble ingredients, and glycerol and salicylic acid, which are fat-soluble. Surfactants need to be added to dissolve fat-soluble ingredients in water. Surfactants can cause foam when shaking, but surfactants do not affect the nutrition of toner.

　　Chi Bo further introduced: "In the production of toner, sometimes in order to dissolve essence and essential oil in water, it is necessary to add surfactant, which can increase the surface tension of the liquid, make all the substances evenly blend and form an oil-in-water system, so that various substances are not easy to delaminate and the storage time is longer."

　　How much foam you shake out can’t judge the substance content, so how to choose the toner that suits you?

　　Xu Yang said that the function of toner is mainly to moisturize and soften the stratum corneum. However, the use of toner should vary from person to person. People with oily skin can use some toner that softens the cuticle or contains alcohol. For people with sensitive skin, it is not recommended to use toner containing alcohol, fruit acid and salicylic acid easily. "Fruit acid and high concentration salicylic acid have exfoliating effect, etc. It is not recommended for people with thin cuticle." She suggested that for people with sensitive skin, if you can’t identify which toner is useful to you, you can use lotion or moisturizer directly without caution.

　　Inclined operation: the emulsion enters the water, but floats on the water surface and contains oilstone ester.

　　Positive solution: Sinking and floating surfaces are mainly determined by density.

　　An emulsion that looks as pure as milk is moisturizing and moisturizing. If a few drops are squeezed and dissolved in water, some emulsions float on the water surface and some emulsions sink into the water. Some emulsion identification methods circulating recently believe that the emulsion floats on the water surface, indicating that it contains oleoresin, which will harm the skin. Is this statement reliable?

　　Regardless of ups and downs, it can’t prove whether the emulsion will harm the skin. Xu Yang said that emulsion is generally composed of oil, emulsifier, preservative, perfume, excipient for adjusting pH value, etc. The density of the emulsion is determined by different preparation formulas and processes, and whether the emulsion floats on the water is determined by the density of the emulsion. If the density is greater than water, the emulsion will sink, otherwise it will float on the water. However, it can’t be said in general that the emulsion floating on the water will hurt the skin, which depends on the specific components and proportions.

　　Chi Bo believes that emulsions containing more oils are easier to float on the water surface. Most of these oils are light oils, such as mineral oils. The amount of oils will affect the skin feel and moisturizing strength of emulsions. Healthy skin is water-oil balance, and the best way to keep skin healthy is to protect the barrier function of skin. Too light and too thick emulsion is not suitable.

　　If you want to choose a suitable emulsion, you can also pay more attention to the ingredient list. Xu Yang believes that the most important function of lotions and creams is moisturizing. If you need anti-aging, you can choose an emulsion with substances such as alcohol A, vitamin C, vitamin E and peptides. Sensitive skin needs some emulsions that have anti-allergic effect and can repair the water-oil barrier, such as those with ceramide, purslane extract and licorice extract, which have certain anti-inflammatory effects. The emulsion containing vitamin C, arbutin, tranexamic acid and other substances is suitable for people who need whitening. Salicylic acid, fruit acid, almond acid and other substances can help fine pores and fight acne.

　　Oblique operation: rubbing salt on lipstick turns black, indicating that it contains lead and mercury.

　　Positive solution: The content of related substances can only be detected after nitration with strong acid.

　　Choosing a powerful lipstick will not only make your lips full and shiny, but also make your whole face feel makeup. Some netizens said, put salt on lipstick and rub it. If there are black particles, it means that the lead and mercury content exceeds the standard, so don’t buy it.

　　In this regard, Qu Mei, a senior engineer of the National Cosmetics Quality Supervision and Inspection Center, responded: "Not reliable." One of Qu Mei’s daily work is to check the quality of all kinds of cosmetics.

　　She said that whether the quality of a lipstick meets the standard needs to be reflected by its lead, arsenic, mercury, cadmium and total number of colonies, mold and yeast, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and other conventional indicators. To complete this detection process, it needs to go through a set of chemical experiments.

　　"When testing, we weigh the lipstick, add strong acid, and then heat it with an electric furnace. The strong acid will fully decompose the chemical composition of lipstick. Then put them in a high-temperature boiling furnace and burn them for several hours to remove all the organic substances in the lipstick, leaving inorganic substances. After dissolving inorganic substances, the contents of lead, arsenic, mercury and cadmium in cosmetics can be detected by atomic absorption or atomic fluorescence. Therefore, it is impossible to decompose lead and mercury just by adding salt at room temperature. " Qu Mei told the Science and Technology Daily reporter that lead, arsenic, mercury and cadmium are all prohibited ingredients in the production of cosmetics. The prohibited mercury can make the skin appear whitening in the short term, but lipstick has no short-term whitening demand, so there is no need to add it. The test results of cosmetics center for many years show that no samples of lipstick containing excessive mercury are found, so consumers don’t have to worry.

　　What are the black particles produced by the friction between salt and lipstick in the online video? Chi Bo said: "Black particles may be caused by sodium chloride destroying the paste system of lipstick, which changes the internal components. However, some merchants will not write all the ingredients in the ingredient list, and the composition of black particles is not easy to judge. "

CCTV News:Wulanchabu, which has the reputation of "Potato Capital of China", is located in the yinshan mountains, with large temperature difference between day and night and abundant sunshine. It is a golden potato planting belt, and its output accounts for nearly half of that of Inner Mongolia Autonomous Region. In these two days, Chayou Houqi in Wulanchabu ushered in a bumper potato harvest.

Reporter Yuan Yi:Do you think the potatoes in my hand are different from what I usually see? Its skin is red, and its name is "Houqihong". There is Ulan Hada volcano in Chayouhouqi where we are located, and these potatoes grow at the foot of the volcano. These potatoes can be said to be "drinking" volcanic magma mineral water and "enjoying" the sufficient sunshine at 41 north latitude.

Reporter Yuan Yi:Potatoes taste really good. Now the potatoes here have entered the harvest period, and harvesting potatoes is also very knowledgeable. Potato skins are thin and easy to be scratched, so they are all sorted manually. The colors of these bags are different. Look, this big sister’s bag is white, and the potatoes in it are quite big.

Farmers:Generally, it is more than three or two.

Reporter Yuan Yi:Smaller potatoes like this will be put in yellow bags.

Reporter Yuan Yi:How much can I charge a day?

Farmers:More than 200 bags.

Reporter Yuan Yi:Collecting potatoes in this field depends on unity and cooperation, and the separation of all the way is another harvest scene. The potatoes planted in this nearly 700-mu field are mainly used for starch processing. This working combine harvester works from turning the soil, shaking the soil and bagging in one go. From a distance, this big guy seems a bit heavy, but from a shooting perspective on the machine, we can see that the potatoes are spinning rapidly on the conveyor belt, and its efficiency can reach 5 mu per hour.

Although the seed potato is small, it undertakes the heaviest task, and one can sell for 3 to 50 cents, because it determines the yield of potatoes.

In addition to deep cultivation of potatoes, extending the industrial chain can double the price of potatoes. Here are all products processed with potatoes, including potato chips and environmentally-friendly disposable lunch boxes. At present, the total value of the whole potato industry chain in Inner Mongolia is 13 billion yuan, so it can be said that "small potatoes" have become the "Jin Doudou" for farmers to increase their income and get rich.

Wisteria (Chinese painting) Wu Guanzhong is selected from the Chinese Art Palace (Shanghai Art Museum) "Chinese Scenery-Lin Fengmian and Wu Guanzhong Art Exhibition"

I read Wang Zengqi’s novel "The Apprentice", in which I wrote that the great grandfather of the fourth season was jealous of the people, and I thought of Mr. Wang himself.

Mr. Wang is famous for painting, and he also wants to be a painter. His father is a painter. He went to The National SouthWest Associated University at the age of 19. Mr. Wang once said that if he failed, he would go to the National College of Fine Arts. However, Mr. Wang has been admitted. If he fails, he will go to the Art College. Perhaps there will be another master in the history of modern painting in China.

The plot of The Appreciator is very simple, telling the story of a great painter and a fruit delivery vendor. It is also a story about a bosom friend. We all know that Yu Boya and Zhong Ziqi, one playing the piano and the other listening to the piano, performed a deep feeling of "high mountains and flowing water". Although Ye San is a fruit vendor, he knows Ji Xianmin and his paintings. Ji Xianmin’s paintings are never seen by people, but he can see them in Yuzryha. Ye San’s appreciation of his paintings is what Ji Xianmin is proud of. Ji Jian-min painted the wrong lotus, and Ye San pointed it out, so Ji Jian-min repainted it and gave it to Ye San. Sometimes Ji Jian-min gave Ye San a painting without the title, and Yuzryha San could sell it. Ye San said, I won’t sell any of your paintings. Sure enough, after Ye San’s death, according to his will, his son buried all the paintings given by Ji Yumin.

Mr. Wang Zengqi knows Chinese painting. He wrote this novel to pay tribute to the literati paintings in China after the Song and Yuan Dynasties (he knew many painters in ancient China), and also devoted his understanding of China ink painting (including techniques) to the text. For example, Mr. Wang painted the ink lotus and wisteria, such as "there is wind in wisteria, and the flowers are messy". Mr. Wang himself painted many wisteria with this kind of messy flowers.

During his visit to Iowa, Mr. Wang gave a speech entitled "My Creative Career". When talking about the relationship between China’s literature and painting, he said that some people say that his novels are poetic novels, but he hopes that some people will say that his novels are picturesque novels.

This is really what Mr. Wang hopes, and it is also the case. Mr. Wang’s works are indeed full of painting meaning-China’s ink spirit, the art of blank space in Chinese painting.

He also visited some art galleries and museums in America. In the Boston Museum, he saw a Song Huizong’s copy of Zhang Xuan’s "Dao Lian Tu" and admired it immensely. He mentioned this painting in a conversation and said, "That thread is so long that I can’t wait to kowtow to it when I write it." In the novel, Mr. Wang used Zhang Daqian to write about the painting of Mohe lotus by Ji Yumin, saying that "the lotus leaves he painted are not hooked, and the lotus stalks are not pricked, and he likes to make them long, and the lotus stalks are very long, and they are all in one stroke." This is all Mr. Wang’s own experience.

During the Spring Festival holiday this year, many families chose to travel. Xiamen, Fujian is a popular destination for Spring Festival travel. Xiamen has a unique style, the city is on the sea, the sea is in the city, beaches, blue sea, blue sky, green trees, beautiful scenery, crowds of tourists and delicious snacks are all people’s impressions of Xiamen. But you may not know that Xiamen once faced environmental and ecological problems such as water pollution and beach degradation. So what kind of butterfly changes has this coastal city experienced before it becomes today’s high-quality, high-value, modern and international Xiamen?

龙年新春，厦门岛上，游人如织。白天，大家在沙滩享受海岛风情；夜晚，厦门市中心的新春灯光秀，介绍这座海岛的前世今生。灯光秀上演的地方叫作筼筜湖。很难想象，这么热闹的一个地方，30多年前，却因为居民增加、企业入驻、生活污水和工业废水排放，变成一个人人避之不及的臭水湖。

上世纪80年代，市民反映非常强烈，筼筜湖治理被政府提上了议事日程。1988年，一场“综合治理筼筜湖”的专题会议在厦门召开，会议主持人是当时的厦门市委常委、常务副市长习近平同志，他为筼筜湖治理定下了“依法治湖、截污处理、清淤筑岸、搞活水体、美化环境”的二十字方针。同时决定，厦门市连续三年每年投入1000万元整治筼筜湖。

时任福建厦门市公用事业局副局长张益河介绍，总书记定下了二十字方针，给生态保护、生态恢复、水污染治理开了先河，是厦门的“第一炮”。

之后，厦门市政府印发了《筼筜湖管理办法》，依法关停、搬迁污染企业，在筼筜湖边建成了第一座污水处理厂。大规模清淤后，清出的淤泥就地堆起湖心岛。筼筜湖和外海的通道被打开，岸边绿化工作跟进。1992年，筼筜湖上举行了第一次龙舟赛。

生态环境部副部长郭芳介绍，当时我们的语境是“发展是硬道理”，当时能够提出不以环境作为代价来换取一时一地的发展，非常有前瞻性。筼筜湖治理二十个字，很好体现了系统治理、科学治理的理念。

36年来，筼筜湖已历经5期大规模治理，市长抓治湖的机制延续至今。今天，湖区已经建立了数字化污水管理系统，通过潮汐纳水，不到3天时间就能将湖水更换一遍，当年的淤泥堆出的湖心岛，如今已经成为了各种鸟类的家园。

今天，筼筜湖不仅是厦门市民最爱去的地方之一，筼筜湖环岛路片区已经发展成为总部经济区，吸引国内外众多企业来此落户。

福建省委常委、厦门市委书记崔永辉介绍，习近平总书记当年提出的二十字方针内含着人民至上、问题导向、系统观念等世界观与方法论层面的深刻思想。36年中，厦门始终遵循这二十字方针，一张蓝图绘到底，一届接着一届干，昔日的臭水湖成为今天市民休闲的好去处和城市会客厅。

习近平同志在厦门工作期间，对生态环境的保护一直非常重视。除了提出二十字筼筜湖治理方针，他主持编写的《1985年－2000年厦门经济社会发展战略》中，用一个章节专门论述了厦门市城镇体系与生态环境问题。2000年，厦门岛内特区发展蒸蒸日上，但是岛外各区的建设差距却很明显，此时的厦门，来到了一个发展的路口。

福建省委常委、厦门市委书记崔永辉介绍，2002年6月，时任福建省省长的习近平同志深入厦门调研，提出了“提升本岛、跨岛发展”战略，进一步阐发了城市发展转型与生态环境保护相统一的思想。

观音山沙滩是厦门东北部最大的沙滩之一，即使寒潮来临，也挡不住游客们亲海的脚步。厦门岛东北部自古以来就有沙滩。然而，20年前，因为牡蛎养殖、外海挖沙等活动，这片沙滩不断退化、侵蚀，几乎变成了乱石岗。当时，厦门岛周边几个海湾都面临类似的问题，海湾内水质恶化，岸边侵蚀严重。厦门要实现跨海发展，必须先对海湾进行综合整治。

时任福建厦门市海洋与渔业局副局长周鲁闵介绍，湾区的整治为整个城市拥湾发展创造了一个很好的条件，我们关注的重点从污染防治向生态系统健康层面来提升。

面对更加复杂的海湾治理，筼筜湖治理二十字方针再次提供了指引。厦门市陆续发布10多部与海洋保护相关的法律法规，各个海湾依法开始了养殖清退、清淤整治、退垦还海，陆地污水被收集处理后再排放入海，组织专门力量日常清理海漂垃圾。厦门市还改造了7道海堤，加速海水流动，推动海洋生态系统的自我修复。

2006年，观音山沙滩也开始了修复，专家们用120万立方米的沙子多期次进行修复，2.4公里的沙滩最宽处达到80多米，比一般沙滩更宽，岸边其他开发的空间虽然被压缩了，却让这里成了厦门最热门的沙滩之一。

同一时间，厦门不同的海湾根据自身的自然条件，有的修建浪漫沙滩步道，有的种植红树林，有的建成湿地公园。自然生态环境改善后，不仅推动了旅游经济的升温，还吸引了其他产业的到来。观音山沙滩对面的商务区，吸引了众多企业总部入驻。

福建省委常委、厦门市委书记崔永辉介绍，厦门始终遵循习近平总书记的要求，坚持可持续发展，坚持发展为了人民，把最美的滨海空间作为公共产品留给了市民和游客。如果说这些舍得到了什么，我想得到的是更高品质的人居环境和更高质量的产业形态。事实证明，高水平保护与高质量发展是可以统一起来的。

进入新时代，在习近平生态文明思想的科学指引下，厦门的海湾型城市建设也进入了新的阶段。军营村是厦门海拔最高的村庄，这里的村民一直靠茶树种植发展经济。1986年和1997年，当时在福建工作的习近平同志曾两次来到这里，每一次都关注这里的环境和发展。

福建厦门市军营村党支部书记高泉伟介绍，第一次讲“山上戴帽 山下开发”，那时候他看到我们村里树木都砍光了，连杂草也割回去当作肥料，其实是叫我们管好山管好水。第二次叫我们既要种茶种果，也别忘了森林绿化。

从军营村流出的山泉滴水成河，流入厦门市最长的河流东西溪，一路向海，最终汇入厦门同安湾。曾经的东西溪，因为上游生活污水收集不全、农业种植养殖污水排放等原因，水质无法保障，也影响了同安湾的环境。

党的十八大以来，我国开始探索生态保护红线划定，厦门市包括军营村在内的大块区域被划入了生态红线，红线内各类造成污染的种植养殖开始清退，经济活动让位于生态涵养。

福建厦门市同安区生态环境局局长王和团介绍，红线是绝对不能开发的，不能有污染开发的。我们建立了生态补偿机制，通过其他（方式）来补偿退养，东西溪分成31个管控区进行分区管控、分区开发。

In 2023, after the publication of the first outline of national land and space planning in China, Xiamen took the lead in compiling and implementing the "Xiamen Land and Space Master Plan (2021-2035)", establishing a protection pattern from the top of the mountain to the ocean, and clearly positioning the functions of each region.

Sun Shuxian, Vice Minister of Natural Resources, said that Xiamen is at the forefront of national multi-regulation, strengthening the management and control of marine and coastal land space, and coordinating and solving the spatial contradictions and conflicts in ecological construction, environmental protection and social and economic development, and has achieved remarkable results.

Nowadays, after more than 30 years of afforestation, the hills around Junying Village are lush, and the village relies on green industries such as tea and eco-tourism to get rid of poverty and become rich. In the area where the East-West Stream passes, after the pollution sources have been cleared, urban rainwater and sewage diversion and rural sewage transformation have been carried out, and the water quality has been greatly improved. After restoration, the river bank near the river basin has become a good place for citizens to relax and entertain.

Tongan New Town in the lower reaches of Dongxixi River, relying on a good ecological environment, has built a livable and suitable Xiamen Science City, attracting a large number of high-tech enterprises and scientific research teams to settle in.

In the past 36 years, starting from the policy of "the Twenty-Cross Lake", Xiamen has developed from a harbor-type scenic city to a bay-type eco-city, which has helped high-quality development with high-level marine ecological restoration, providing valuable experience for other cities in China to balance high-level protection and high-quality development.

自然资源部副部长孙书贤介绍，“厦门实践”生动诠释了人与自然和谐共生的深刻内涵，有力证明了碧海银滩也是金山银山，启示我们必须注重高质量发展和高水平保护修复相统一，站在人与自然和谐共生的高度谋划发展。

国家发展和改革委员会副主任赵辰昕介绍，习近平总书记指引厦门走出了一条人与海洋和谐共生的高质量发展道路。下一步，国家发展改革委将把坚持高质量发展作为新时代的硬道理，将习近平生态文明思想的“厦门实践”重要的经验做法，总结运用到发展改革工作当中，深入推进陆域、流域、海湾、海域高水平保护和高质量发展，推进美丽中国建设不断迈向新的台阶。

今天的厦门“抬头仰望是清新的蓝，环顾四周是怡人的绿”。从筼筜湖治理的二十字方针，到厦门海湾的科学治理和修复，再到建立从山顶到海洋的生态保护格局，36年时间，厦门以生态环境治理、生态系统修复、生态网络构建，为城市发展创造良好生态基底，探索出了一条高质量发展之路，也成为了向世界展现中国特色生态文明建设的窗口。每一片山海都是宝贵的自然资源，需要我们好好珍惜，用心爱护，才能成为造福百姓的美丽风景、助推经济的金山银山。

　　Tomorrow, our mobile phone will be screened by Buffett again!

　　At 22:15 Beijing time on May 4th, the annual shareholders’ meeting of Berkshire Hathaway will be held in Omaha, USA. It is estimated that about 30,000 shareholders will attend, and millions of people will watch it online. The most noteworthy issues of this shareholders’ meeting include:

　　Who is Buffett’s successor? — — Bashen is 88 years old and Munger is 95 years old.

　　What about Berkshire’s more than $110 billion in cash? — — Look at the company’s share price of $320,000. Do you still think Maotai is expensive?

　　The repurchase scale will be as high as $100 billion? — — There are not many good companies worth buying, so I have to buy myself.

　　However, for A-share investors, they may be more concerned about this question: What does Buffett think of the China market? Which stocks of A shares meet its stock selection criteria?

　　Which A shares can enter the eyes of the law?

　　There are many criteria for Buffett’s stock selection, but there are clear quantitative criteria. He only said one sentence, that is, the annual return on net assets (ROE) is greater than 20% for 10 consecutive years.

　　The so-called return on equity (ROE) is the ratio of company profits to shareholders’ equity. It represents the investment income of investors, in short, how much money the enterprise can earn for investors.

　　ROE is a measure of a company’s long-term profitability. The higher the ROE, the higher the net profit it earns with the same shareholder capital investment. According to Coca-Cola’s standard, that is, keeping the ROE above 20% for 10 consecutive years, it is the company that Buffett may like.

　　So, which companies in A shares meet Buffett’s standards?

　　Wind data shows that in the 10 years from 2009 to 2019, among the listed companies whose ROE (deduction/dilution) continuously exceeds 20%, there are only five listed companies in A shares, namely Kweichow Moutai, Haitian Weiye, Gree Electric, Yanghe and Chengde Lulu.

　　The average share price increase of these five listed companies in the past 10 years is 690.49%, and the annualized rate of return is 22.97%. The biggest increase is Kweichow Moutai, which rose 12 times in 10 years, followed by Gree Electric, which rose more than 11 times in 10 years.

　　If we relax the ROE standard to 15%, that is, we will keep the ROE above 15% for 10 consecutive years. So, how many companies in A shares meet this standard?

　　Wind data shows that in the 10 years from 2009 to 2019, there were 14 listed companies with ROE (deduction/dilution) exceeding 15% continuously, namely Shuanghui Development, Kweichow Moutai, Haitian Weiye, Hikvision, Gree Electric, Huadong Medicine, Yanghe, Chengde Lulu, Hengrui Pharma, Chongda Technology, dongfeng shares, Fuyao Glass and so on.

　　The average share price increase of these 14 listed companies in the past 10 years is 551.72%, and the annualized rate of return is 20.62%. Among them, Hengrui Pharma, Kweichow Moutai and Gree Electric rose more than 10 times, while Huadong Medicine, Hikvision and Golden Mantis rose more than 5 times.

　　Is Bashen’s strategy unacceptable?

　　In the past 10 years, what is the investment income of Warren Buffett?

　　According to media calculations, if an investor bought a dollar of Berkshire stock 10 years ago, the return today is about $2.4, but if this dollar is invested in the Standard & Poor’s 500 Index Fund, the return today is about $3.2. In other words, in the past 10 years, the income from investing in Berkshire has not been as high as that from investing in the S&P 500 index fund.

　　In 2018, the worst performance of global financial assets in the past 100 years, the "stock god" seems to be unhappy. Suffering from various "thunder" such as Apple’s performance falling short of expectations and Kraft Heinz’s performance changing face, Berkshire lost more than $25 billion in the fourth quarter of 2018, but still earned more than $4 billion in the whole year.

　　But in A-share market, Buffett’s stock picking strategy still seems feasible.

　　In the past decade, 108 A-share stocks have increased more than 5 times, and 29 have increased more than 10 times. The median ROE of these 29 stocks is 14.88%. During this period, the Shanghai Composite Index rose by 24.72%, the Shanghai and Shenzhen 300 Index rose by 50.2%, the CSI 500 Index rose by 74.59%, and the Shenzhen dividend index rose by 132.51%.

　　Obviously, those companies with long-term earning ability and dividend-paying ability can surpass the market if they buy at a reasonable price. However, it should be pointed out that value investment is by no means equal to an ROE index, and the stocks selected according to it are not necessarily suitable investment targets, but only help us find out those good companies more easily.

　　The above data illustrates two problems:

　　First, as Buffett said: "By investing in index funds regularly, an investor who knows nothing can usually beat most professional fund managers." Buffett has recommended index funds for more than ten times.

　　In Buffett’s view, the vast majority of investors rarely invest in index funds, and as a result, their performance in investing in stocks is mostly just mediocre, or even disastrous. There are three main reasons for the loss of investment stocks:

　　1. The cost is too high, investors buy and sell too frequently, or the expenses are too large;

　　2. Investment decisions are made according to gossip or market trends, rather than after careful consideration and quantitative analysis of listed companies;

　　3, blindly chasing up and down, buying or selling at the wrong time.

　　Second, practice has proved that the companies with the strongest earning power in A-shares can bring rich long-term returns to investors.

　　The overall growth level of A-share listed companies is better than the average level of social enterprises. The long-term stock price trend charts of leading enterprises such as Gree Electric, Vanke A, China Merchants Bank, China Ping An and Fuyao Glass are all consistent with the development path of enterprises.

　　The method of value investment has not failed in A-shares. In fact, A-shares will create a good opportunity for value investors to pick up bargains every few years, making it easier for investors to meet good prices. Numerous masters have emphasized that all investment is to find a good industry, a good company and a good price.

　　Finally, Buffett has bought two China stocks so far — — China Petroleum and BYD.

　　In 2003, Buffett bought H shares of China Petroleum at a price of HK$ 1.6, and cleared the position when the share price reached HK$ 13.5 in 2007, with a four-year income of more than 7 times (the reinstatement factor has been considered, the same below). When Buffett bought it, the P/E ratio of China Petroleum was only 5 times, while when China Petroleum was listed on A-share in 2007, the P/E ratio of 48 yuan’s opening price was as high as 63 times.

　　In 2008, Buffett subscribed for 225 million shares of BYD at a price of about HK$ 8 per share. At present, Buffett still holds shares in BYD, and its latest share price is HK$ 53.55, and its income has exceeded five times. When Buffett bought BYD shares, the corresponding P/E ratio was only 10.2 times. At present, its latest P/E ratio is 39.29 times.
