"Don’t be a broken ear root in the future. Pull out everything in the yard. Experts say it contains carcinogens, and if you eat it, you will get cancer." Uncle Li kept talking to his wife about the harm of broken ears.

"I don’t believe it when I break my ears to clear away heat and detoxify, and it tastes good. Don’t watch those people talk nonsense every day."

"What nonsense? Look at this article. It says that the root of the ear contains aristolochic acid, which is a carcinogen and can’t be eaten. It is also signed by experts!"

"I don’t believe it! I’ve been eating it for decades. Is there a problem? It’s still alive and kicking. "

"Hum, anyway, I won’t eat the roots of broken ears in the future, and you shouldn’t be my share, you are stubborn!" Uncle Li didn’t listen to his wife, so he left without looking back.

Cynanchum auriculatum, also known as Houttuynia cordata Thunb, is not only a vegetable, but also a Chinese herbal medicine. Because of its unique taste and the effect of clearing away heat and toxic materials, it is deeply loved by some people. However, in recent years, there are more and more sayings about "the root of broken ears causes cancer", saying that it contains aristolochic acid carcinogen, which will cause cancer if eaten. Is this statement true or a rumor?

01

Houttuynia cordata Thunb is a harmful grass,

Containing aristolochic acid, is it nephrotoxic and carcinogenic?

Houttuynia cordata Thunb is controversial because it contains aristolochic lactam alkaloids. Then there are many types of alkaloids, including an aristolochic acid component. Because of its strong nephrotoxicity and hepatotoxicity, in 2008, aristolochic acid was officially listed as a class 1 carcinogen by the International Agency for Research on Cancer. Moreover, in 2015, China’s National Pharmacopoeia also deleted three Chinese herbal medicines containing aristolochic acid, namely Aristolochia manshuriensis, Fangji and Aristolochia. Does that mean houttuynia cordata is carcinogenic and can’t be eaten?

Of course not. Aristolochic lactams are divided into many different types. At present, the substances known to be toxic and carcinogenic are aristolochic acid and aristolochic lactam I.. The components in Houttuynia cordata Thunb are aristolochic lactam BII, AII and FII, which are completely different from aristolochic acid I. At present, there is no evidence that these substances in Houttuynia cordata Thunb are toxic or carcinogenic. People who love houttuynia cordata can eat it with confidence.

02

I ate too many vegetables.

Can cause cancer? Don’t be fooled again

1. Eating fresh fungus is easy to induce skin cancer?

The reason for this statement is that there is a light-sensitive substance porphyrin in fresh auricularia auricula, which may cause skin itching, edema and other symptoms after entering the body by sunlight, and even induce skin cancer.

In fact, there are light-sensitive substances in many foods, including celery, and it is not unusual for vegetables to contain this ingredient. The current research shows that the occurrence of porphyria is mainly related to the abnormal metabolism of porphyrin in the body caused by genetic factors, and has little to do with the porphyrin ingested in the diet, so it is safe to eat it every day.

2, bergamot contains carcinogens, can not eat?

It is rumored that the fried bergamot will produce acrylamide, which is considered as a carcinogen, and long-term intake will increase the risk of cancer.

Undeniably, fingered citron will undergo Maillard reaction after being fried at high temperature, and then acrylamide will be generated. However, this reaction is not unique to bergamot, but also widely exists in fried food, baked food and cooking. Therefore, bergamot itself does not contain acrylamide, which is caused by the cooking method. It is recommended to pay attention when cooking. There is also acrylamide, a class 2A carcinogen, which may cause cancer to human beings. At present, there is no clear evidence that people will cause cancer if they eat it. Again, the occurrence of cancer is related to many factors and cannot be simply attributed to a certain food.

3. Does the herbicide contained in rootless bean sprouts cause cancer and teratogenesis?

2,4-Dichlorophenoxyacetic acid plant growth regulator is used in the production of rootless bean sprouts, which is widely used in agriculture. When used in low concentration, it will promote the growth of bean sprouts and inhibit the formation of roots and buds. When used in high concentration, it can really achieve the effect of herbicide, but this concentration will also make bean sprouts unable to grow.

4, raw tomatoes, can lead to gastric cancer or intestinal cancer?

Raw tomatoes contain a lot of alkaloids (solanine), which may cause dizziness, vomiting, diarrhea and other food poisoning symptoms. It is not exaggerated to lead to gastric cancer or intestinal cancer. The occurrence of cancer is related to many factors and will not be directly caused by the intake of a certain food. However, it is still not recommended that you eat raw tomatoes. However, as the maturity of tomatoes increases, the components of Solanum nigrum will be greatly reduced, and this problem will not occur when cooked tomatoes are eaten.

03

Five kinds of food are the culprit of cancer.

According to the danger to human beings, the International Center for Research on Cancer divides the carcinogenic factors into 1 category, 2 category, 2 category, 3 category and 4 category. Among them, class 1 carcinogen means that there is sufficient evidence to prove that it has carcinogenic risk to human body. Through combing, it is found that some carcinogenic factors are hidden in our food, mainly the following five kinds.

Salted fish, pickles, etc.

A large amount of nitrite will be produced in the process of food curing, and nitrite will combine with protein to produce nitrosamines after entering the body, which is a kind of carcinogen and will increase the risk of esophageal cancer, liver cancer, colon cancer and other cancers.

Mildew food

Mildew food is likely to contain aflatoxin, especially foods with high starch content such as peanuts, corn and nuts, which are more likely to be produced after mildew. Aflatoxin is a highly toxic and carcinogenic substance. Intake of 1mg can cause cancer in the body.

barbecue

Carcinogens such as benzopyrene and polycyclic aromatic hydrocarbons may be found in the smoke generated by charcoal burning, the lampblack dripping from meat oil and burnt food when meat is roasted at high temperature. Eating a lot of barbecue for a long time will increase the risk of cancer in the body.

alcohol

Alcohol is a clear carcinogen, and data show that more than 3 million deaths worldwide are related to drinking every year. Smoking and eating a lot of high-fat food while drinking will double the harm to the body. The Lancet magazine directly pointed out that there is no so-called safe amount of drinking, and the best amount of drinking should be 0.

areca

The research published in The Lancet-Oncology pointed out that arecoline in areca catechu has carcinogenic effect, and it was identified as a class 2B carcinogen. Moreover, the fiber in betel nut is very rough, which will continuously damage the oral mucosa when chewing. In the process of repeated injury and repair, the risk of oral cancer will increase significantly.

The occurrence of cancer is related to many factors, and it is unscientific not to blame the culprit on a certain food. Maintaining good living habits and regular physical examination every day is the right way to prevent cancer.

Peanut oil:

It is high-quality cooking oil and frying oil, easy to be digested and absorbed by human body, and contains more than 80% unsaturated fatty acids. Eating peanut oil regularly can protect the blood vessel wall, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease.

Rapeseed oil:

The human body can digest and absorb rapeseed oil up to 99%. Rapeseed oil has a certain effect of softening blood vessels, and the cholesterol content is low, so people who have requirements for cholesterol intake can safely eat it. But its erucic acid content is high, and patients with coronary heart disease and hypertension should eat less.

Soybean oil:

As one of the most commonly used edible oils, it contains a lot of linoleic acid and abundant.

Rich lecithin is good for human health.

Sunflower seed oil:

Sunflower seed oil is rich in linoleic acid and other essential unsaturated fatty acids, which can reduce the deposition of cholesterol in blood vessels. The content of a- tocopherol in sunflower seed oil is higher than that in common edible oil, which is a kind of high-quality edible oil beneficial to human health.

Corn oil:

The unsaturated fatty acid content of corn oil is as high as 80%~85%, and it is rich in vitamins A, D and E. Long-term consumption is beneficial to diseases such as hypertension, hyperlipidemia and diabetes.

Blending oil:

Blended oil refers to edible oil made from more than two kinds of vegetable oils. The fatty acid content of blended oil is more balanced than that of single edible oil, which embodies the concept of food diversity and nutritional balance.

2019 Huawei Developers Conference was held and HarmonyOS OS was officially released. (Source: vision china)

"HarmonyOS" is the beginning of the world, and China is promising.

For a long time, Chinese suffered from not having its own chip and operating system. Now, from the mythical beasts of Huawei Kirin and Kunpeng to HarmonyOS, the old balance of global science and technology has been broken one after another, and Huawei has captured the peaks in the science and technology competition. So, what kind of new revolution will Huawei lead? Will the world start a fight to trap the "beast"?

The best time or the worst time?

"What era are we in today?"This is the first question raised by Yu Chengdong, CEO of Huawei’s consumer business, at the Huawei Global Developers Conference on August 9th.

What kind of era, what kind of technology is needed. Huawei’s answer is this:

First, the era of internet of everything and intelligent whole scene.

I believe everyone is familiar with the concept of "Internet of Everything". Huawei is leading everyone to enter the "intelligent era of the whole scene of the Internet of Everything". To achieve this goal, we need to create a brand-new ecology and experience, and we need strong operating system support.

The significance of "HarmonyOS" system is magnified in historical coordinates, which is more intuitive. In the era of PC, the Windows operating system invented by Microsoft occupies more than half of the country. In the era of mobile internet, Google and Apple established the Android ecosystem and iOS system respectively, which basically divided the smartphone market. At present, it has become a consensus that everything can be connected, but who can lead the coquettish?

All parties have made great efforts. HarmonyOS OS’s ambition is to be born for the Internet of Things era, not just mobile phones. Huawei’s architecture is called "1+8+N" & mdash; — 1 is a smart phone, 8 includes PC, tablet, car, sports health, wearing, AR, VR, smart big screen, intelligent audio, etc. N is a large number of IoT devices.

Second, the technology of operating system has entered the era of "microkernel".

At present, Google’s operating system is based on macro-kernel architecture, and Fuchsia, the next generation operating system with micro-kernel, is being developed. Apple uses different operating systems on different devices, mainly macro kernel, and also introduces some micro kernels. As far as the trend is concerned, "microkernel" is the development direction of global operating system. HarmonyOS system chose microkernel.

Simply put, the macro kernel is a "big manager", and the famous Linux and Uinux systems are macro kernels. This system puts all the supported services in the kernel, which is more efficient, but the problem that comes with it is more and more "bloated". For example, the Android system has 100 million lines of code, and the kernel has more than 20 million lines. We often use only 8% of the kernel.From 2G memory to 8G memory, the mobile phone needs more and more memory to ensure smooth operation, and the price is getting more and more expensive.

Microkernel is an "information transfer station", which places more service programs outside the kernel, and the kernel only places frequently used codes, thus greatly reducing the memory pressure. In fact, the memory requirements of many devices are very small. According to Huawei,Compared with Android and Apple, HarmonyOS microkernel is greatly improved in security and convenient in application development.

HarmonyOS’s "short board"

The HarmonyOS system makes people "unconscious". As a subversive, what is the attitude of the world towards HarmonyOS?

Not long ago, Huawei has encountered multiple technical blockades. The US government had planned to include Huawei in the so-called "entity list", and Google once claimed that Android system no longer supported the newly released Huawei mobile phone. For another example, some countries still have resistance to Huawei’s participation in 5G construction.

Operating system, from the technical level, can overcome difficulties and concentrate on breaking through in a certain period of time. The cultivation of the ecological level is not a one-off event. Can the upstream and downstream accept it? How high is the cost of conversion? It depends not only on whether HarmonyOS’s experience is "worthy of the name", but also on letting users vote.

Ecology is like air, water, soil and language that human beings need. From the perspective of Apple’s ecology, it is not only an excellent product company, but also has a rich App application ecology and practical peripheral accessories. In terms of corporate strategy, Apple is shifting its focus from hardware to software to strengthen its own "moat". After several years of development, Android system has the first share in the market, and most companies have formed a "path dependence" on Android system research and development.

Giants such as Microsoft, Samsung and Nokia have launched Windows Phone, Tizen and Symbian systems, and the result has not shaken the ecological pattern of Android and Apple. An important reason is that,There is not a lot of software and product support, even though their own hardware is very powerful.

Judging from the conditions Huawei has, as an equipment manufacturer, it has a good hardware ecology; As an enterprise benchmark, it has the support of the domestic big market. However, there is still a lot of work to be done to make potential competitors at home and abroad accept and carry the HarmonyOS system. Moreover, HarmonyOS has not been tested by more reality. In terms of application, HarmonyOS’s choice is to first carry it on a "peripheral device" such as Glory Smart Screen, rather than a smart phone.

So in a short time, it is difficult for HarmonyOS to replace Android. The advent of HarmonyOS is bound to challenge Android and Apple, which are both in the hands of American companies. At present, it remains to be seen how Google and Apple will take over. It is foreseeable that the competition will be fierce. Ren Zhengfei said: "We do a good job in ecological construction ‘ Long March ’ Preparation. "

What is Huawei’s response to the unfriendly external environment?

You can call it"Strategically high-profile, tactically low-key."Judging from Huawei’s publicity, Ren Zhengfei revealed that "HarmonyOS is 60% faster and smoother than Android." Yu Chengdong claims to be "ready to use" and "the development workload of migrating Android ecological applications to HarmonyOS OS is very small". This will inevitably make Google and Apple feel "unsuitable".

Huawei also emphasized a kind of self-confidence called "open source". We know that the success of Android is inseparable from open source. Open source allows more developers and users to join the Android ecosystem, helping it to continuously improve and mature.

In view of the strong ecological barrier of Android system, Huawei’s strategy is to "give priority to Google’s Android operating system. If the Android operating system can’t be used, HarmonyOS can be enabled at any time.. "Huawei flashed the challenger’s posture, also opened the door to cooperation, and walked very cautiously.

It should be said that Huawei is holding high and fighting high on the road of technology, but the road of ecology is "long and long".

From zero to one

The advent of HarmonyOS made national pride boil. It has to be said that the background of Sino-US trade friction and the concentrated suppression of Huawei by the United States have accelerated the process of "turning a spare tire into a regular one" in HarmonyOS. The reason why Huawei has survived the "storm" is that it has taken precautions and worked hard many years ago. In the development of HarmonyOS, 5,000 engineers struggled day and night and sharpened their swords for seven years.

To some extent, Huawei is quite "fighting alone". In the future high-tech track, it is foreseeable that the United States will continue to keep a high pressure on China’s technology enterprises. The rise of science and technology in China needs more ambitious and persistent companies like Huawei.

One question worthy of reflection is that,Although the number and scale of Internet technology giants and unicorn companies in China are among the best in the world, they are market-driven companies thanks to China’s huge domestic market and population base. When we have long been used to domestic manufacturers fighting for hardware, marketing and price, Huawei talked about "soft power" such as operating system and ecosystem for the first time at the press conference, which is quite the weather of Apple and Google.

The shortcomings of basic science in China are outstanding, and the original achievements are lacking. The situation that key core technologies such as operating systems and chips are controlled by people has not fundamentally changed.Practice has repeatedly told us that,Key core technologies can’t be bought, bought or discussed. "Difficulties are like springs. If you are strong, it will be weak, and if you are weak, it will be strong." China has made up its mind to independently develop its own core technology and make great efforts in the field of "sticking its neck" to meet more complicated global competition.

HarmonyOS, from zero to one, is Huawei’s "groundbreaking" move, and it is also a breakthrough in China’s science and technology.

Many people laugh at the fact that cars are farting by taking off their pants. Obviously, there is an internal combustion engine available. Why not directly drive the car, but also convert it into electricity, and then let the motor drive the car? This is not what farting is.

I thought they were just spraying. But it was later discovered that cars do have various problems. Originally, it was to solve the problem of endurance, but later it was found that the biggest problem of a car was not endurance at all, but something else. Why do you say that?

First of all, cars rely too much on household charging piles. It can be said that if you have a household charging pile at home, it must be a good enjoyment to own a car, but if not, charging every day will make you feel broken.

There is an obvious problem. Its pure electric cruising range is not as high as that of a pure electric vehicle, so you don’t have to consider the problem of fast charging from the initial stage of design. You only need to charge slowly, and you can fully charge it in one night.

But the problem is, when you really have it, you will find that if you drive by electricity alone, the price is really too cheap. But once the car has no electricity and has to run on oil, you will feel very unhappy. Why use expensive oil when there is cheap electricity? So you have to do everything you can to recharge.

The last situation is that you have to go outside to charge the charging pile every few days, so the pleasure of using the car will soon disappear and people will become slaves of the car.

Also, the car’s power loss experience is really bad. If you drive in pure electric mode, you will feel too comfortable, the vehicle is extremely quiet and the acceleration is very fast. But once you enter the state of running without electricity, the situation becomes completely wrong.

Especially when you go uphill, you can obviously feel the lack of motivation, giving people the feeling that you have no strength to drag your feet. The third aunt on the road is slow enough. It is estimated that it is not as fast as the third aunt on the road when going uphill.

Once the range extender is involved, you will feel obvious vibration and noise, and the driving comfort will be out of the question. The gap between this experience and pure electric driving is too big, which will give people a very obvious psychological gap.

Finally, the charging speed is too slow. If you just run in the city and have a charging pile at home, it’s a big deal to sleep and unplug it the next morning, but what should you do if you travel for a long time?

If you want to charge, you have to endure an hour or more of charging time, which is simply unacceptable to most people. But if you want to refuel, think about how high the oil price is now. You can obviously use electricity. Are you willing to refuel? This will make you feel very entangled.

I believe that many people who have bought models have similar puzzles. As for how to solve this problem, I am afraid that we can only wait for solid-state batteries to really appear. At least after the appearance of solid-semi-solid batteries, this problem will be solved to some extent.

Historical photo taken more than 100 years ago: Emperor Guangxu (middle)

Guangxu statue

　　The mystery of Guangxu’s death with different opinions finally came to a scientific conclusion on the occasion of the centenary anniversary of the poor emperor’s death-Guangxu died of arsenic poisoning. Tomorrow morning, the National Compilation Committee of Qing History Project will hold a "Report on the Death of Emperor Guangxu of Qing Dynasty" in Beijing, and publish a 10,000-word report detected by modern criminal investigation and high-tech means. The 20 episodes of large-scale TV documentaries, which fully record the process of solving this century-old mystery, have also entered post-production in CCTV.

　　The dead emperor was only 37 years old.

　　On the evening of November 14th, 1908, Emperor Guangxu died. The next afternoon, Empress Dowager Cixi also died. Guangxu, 37, died in front of Cixi, 74, and only one day later, causing many speculations. Some people think that Cixi did not want Guangxu to regain power after her death, and sent someone to poison Guangxu. Some people say that Yuan Shikai betrayed Guangxu during the Reform Movement of 1898, fearing that Cixi would be retaliated by Guangxu after her death, so he bribed eunuchs and poisoned them. Li Lianying, the eunuch, was also said to have poisoned him, because he learned in Guangxu’s diary that after the death of Cixi, Yuan Shikai and he would be punished. However, some people think that Guangxu died of physical weakness.

　　The cause of death is inconclusive for a hundred years.

　　In the past 100 years, there have been numerous papers on Guangxu’s death, but no academic conclusion has been reached. In 2003, Zhong Liman, the director of CCTV documentary, occasionally learned that in 1980, the cultural relics management office of Qing Xiling had cleaned and re-closed the coffins of Guangxu and Longyu (stolen in the late 1930s), and their hair was moved outside the coffins and kept in the warehouse of Qing Xiling. So Zhong Liman began the process of testing research and filming TV documentaries for five years.

　　Criminal investigation high-tech detection

　　The "Report on the Death of Guangxu", which will be released completely for the first time tomorrow, will also be signed by the Cultural Relics Management Office of Qing Xiling, the Research and Design Institute of Reactor Engineering of China Institute of Atomic Energy and the Forensic Identification Center of Beijing Public Security Bureau. They successively extracted two strands of Guangxu’s hair, which were 26 cm and 65 cm long respectively, washed them, dried them, cut them into 1 cm long sections, numbered them one by one, weighed them and packaged them, and then detected the element content in Guangxu’s hair by nuclear analysis method.

　　The results showed that Guangxu’s hair contained high concentrations of elemental arsenic, and the contents of different sections were very different. The peak value of arsenic in the first hair appeared in the 10th section (2404 μ g/g), and the peak value of arsenic in the second hair appeared in the 26th section (362.7 μ g/g) and 45th section (202.1 μ g/g). At the same time, the arsenic content in hair tested by comparison is 0.14 to 0.59 μ g/g for contemporary people, 9.20 μ g/g for the Queen Longyu who was buried with Guangxu at the same time, and 18.2 μ g/g for the hair of a forage official in the late Qing Dynasty.

　　The poisoning forensic doctor has a conclusion

　　Later, according to the standard requirements and methods of forensic examination, they took samples of Guangxu’s remains and clothes for testing. As a result, the arsenic content in the scapula, spine and the stomach area, frenum and collar and shoulder of each piece of clothing was very high. The arsenic content of inner clothing is much higher than that of outer clothing. Then, the comparative experiments were carried out on the objects in Guangxu’s coffin and tomb and the soil and water in the mausoleum. The results showed that the high concentration of arsenic in Guangxu’s hair did not come from environmental pollution. Finally, they came to the conclusion that the high content of arsenic in Guangxu’s hair was not produced by natural metabolism of chronic poisoning, but from external contamination; A large number of arsenic compounds once remained in the stomach and abdomen of Guangxu’s corpse, and the decay process of the corpse was redistributed, eroding the remains, hair and clothes. And arsenic compounds are also highly toxic arsenic.

　　After scientific calculation, the total amount of arsenic ingested by Guangxu was obviously greater than the lethal dose.

　　The murderer has yet to be studied.

　　While testing, Zhong Li searched the archives of the late Qing Dynasty, medical records of Guangxu, personal memoirs of imperial doctors who participated in the diagnosis and treatment before Guangxu’s death, diaries of military ministers and Juzhu officials, sorted out the situation 10 days before Guangxu’s death, and combined with the discussion of arsenic poisoning by modern forensic doctors, discussed the types of arsenic poisoning in Guangxu, as well as the lower and upper limits of poisoning time.

　　This project, which was completed by non-Qing scholars, has been attached great importance to by the National Qing History Compilation Project, and has been included in the "Special Project on Major Academic Issues" of this project. Perhaps, the 20-episode documentary "The Death of Guangxu" will also be included in China’s official history "The History of Qing Dynasty". The research group also wrote a monograph on the research and test of Guangxu’s death, which will be published soon.

　　But who poisoned Guangxu? This remains to be further studied or discovered by historians.

　　Reporter Yang Liqiong in Beijing (Beijing, Today)

Editor: Tang Liang

CCTV News:The reporter learned from The Export-Import Bank of China on July 24th that in the first half of this year, the Export-Import Bank played the role of policy-based finance as a short-board and inter-cycle adjustment, and continued to increase the supply of funds in the foreign trade field. In the first half of this year, the accumulated foreign trade industrial loans exceeded 900 billion yuan.

According to reports, in the first half of this year, the Export-Import Bank successively introduced a number of bail-out measures, continuously increased the supply of funds in the foreign trade field, reduced fees to benefit foreign trade enterprises seriously affected by the epidemic, gave SMEs deferred payment and non-repayment of loans, and innovatively designed a comprehensive product package to serve the development of new foreign trade formats and new models, constantly stimulating the vitality of market players and promoting the high-quality development of foreign trade.

By the end of June, the balance of foreign trade industrial loans of the Export-Import Bank was 2.68 trillion yuan, a year-on-year increase of 19%. In the first half of the year, foreign trade industrial loans totaled 920 billion yuan, a year-on-year increase of 22%.

In addition, by the end of June, the balance of local and foreign currency loans of the Export-Import Bank was nearly 5 trillion yuan, a year-on-year increase of over 10%. In the first half of the year, loans totaled 1.25 trillion yuan, a year-on-year increase of 14%.

　　"Cooking in your own kitchen is comfortable."

　　Our reporter He Yong

　　In Houguaibang Hutong, Dongcheng District, Beijing, an old "Paizilou" has taken on a new look after three months’ renovation, with Spring Festival couplets, blessings and window grilles on the doors of every household, which is a jubilant scene.

　　Zhou Yanbin, 68, is busy in the kitchen wearing an apron. The reporter saw that in a space of about 6 square meters, there are all kinds of cooking stoves, range hoods and lockers, and all kinds of ingredients are on the table, just waiting for the pot. "Cooking in your own kitchen is comfortable!" Zhou Yanbin said happily.

　　"Last year, you see, this building is not like this at all. It is not easy to really belong to your own kitchen! " Zhou Yanbin’s wife, Zhao Xijin, told reporters, "This is an old building built in the 1950s. It originally belonged to the office of the unit. Later, the unit distributed the rooms on the third and fourth floors of the building to employees as dormitories. Each floor has a public bathroom and kitchen, and all residents in the floor share a water meter."

　　For decades, residents have "enclosed" public toilets and kitchens for their own convenience. The building is full of small compartments separated by residents’ private construction, and the lock on it becomes a private kitchen. Opaque glass blocks are used in public toilets, and a water heater becomes a private bathroom. Sewers are often blocked, and private wires are pulled on the roof of the corridor, which poses a serious safety hazard.

　　Zhou Yanbin introduced that last year, Chaoxi community joined forces with tap water, power supply and other units to transform the problems of water use and circuit aging in the building. The biggest change is that every household has its own kitchen and bathroom, and the community has re-divided the original public space of about 50 square meters on the floor, with each household being about 7 square meters.

　　"Does the cost of renovation need to be borne by residents?" The reporter asked questions. Zhou Yanbin said excitedly, "This renovation not only confiscated a penny from us, but also lasted for three months. During this time, we also paid rent subsidies!"

　　Humar Khan, Qitai County, Xinjiang:

　　"The road is repaired and the county seat is nearby."

　　Our reporter altak.

　　"It didn’t take you long to come here, did it? This road has changed a lot! " During the Spring Festival holiday, the reporter visited relatives in Kuangou Village, Qitai County, Xinjiang, and chatted with relatives. When it comes to the road from the county seat to the village, Uncle Humar Khan’s tone is full of excitement. "In the past, it took us three or four hours to get back to the village from the county!" He said that although Kuangou Village is only 50 kilometers away from the county seat, the road conditions are complicated, and it is impossible to pass through a river when there is a flood. There is also a dangerous mountain road, which is narrow and bumpy and can only pass in one direction.

　　Now, the dirt roads have become asphalt roads, the bridges across the river have been strengthened, the rugged mountain roads have been widened, and protective fences have been installed on the roadside. "Now into the county seat, it will arrive in less than an hour. What do you mean?" He smiled and said, "The road is repaired, and the county seat is nearby!"

　　"Why don’t you say, we don’t take the bus now?" My second aunt also joined us in the conversation. In the past, villagers could only travel by a bus. They got up before dawn to wait in line for the bus. If they missed it, they had to wait for the next day.

　　Nowadays, the number of buses entering the village has increased to three times a day, but some villagers have stopped taking buses. There are all kinds of cars in the village. If you want to go to town, you can take a lift and leave.

　　"The road has been repaired, and the days are booming. What a change!" The second uncle said excitedly.

　　Changyin, Pizhou City, Jiangsu Province:

　　"The most important thing is to do things in a down-to-earth manner"

　　Our reporter Gong Xiangjuan

　　Going home for the New Year, the reunion of middle school classmates is a must. The enthusiastic convener of this year’s gathering of graduates from Yanjia Middle School in Pizhou, Jiangsu Province is still the old monitor Wang Lu, who started his own company to produce asphalt mixture after he retired from the army.

　　Talking about business, Wang Lu looked relaxed. "Last year was better than the year before!" Wang Lu said that now that the policy is strictly controlled, enterprises that meet the environmental protection standards will not suffer losses. His company is now in place with environmental protection measures, and its business scale will double in 2017!

　　While speaking, the thinnest classmate sitting opposite often interjected, "It’s all done in this way. When I graduated from college and just went to work in a decoration company, I was completely blind. Later, I was not only able to design independently, but also undertook the later construction. Now, the business grows every year! "

　　"Tell me about your unique skills?" The students booed and asked. "There is no trick, the main reason is that I am more practical," Chang Yin said seriously. "New customers are introduced by old customers and passed on from mouth to mouth. Let’s young people, just starting, it is most important to do things in a down-to-earth manner! "

　　The sound of blessing and clinking glasses are intertwined, and everyone’s eyes are shining with happiness.
