Legend of Chongqing Specialty (111) The Origin of Chongqing Hotpot! The truth may surprise you …

Chongqing city looks like a pot of hot pot!

Surrounded by two rivers, is it like a pot of hot pot soup? And the Yuzhong Peninsula, like a piece of fresh hairy belly floating on the hot pot, is scalding … Some people say that Chongqing is more like a mandarin duck pot, with red soup on the Yangtze River and clear soup on the Jialing River.

No wonder Chongqing hot pot is famous all over the world. Chongqing looks like it, which is very good with hot pot.

Five conjectures

For decades, many people have been trying to research the origin of Chongqing hot pot, but they have not found a convincing source. I combed it, and there are five main origins of Chongqing hot pot mentioned in various articles. I call them "five conjectures" about the origin of Chongqing hot pot.

Conjecture 1: the origin theory of jiangbei street.This is the view of Li Jieren, a famous Sichuan writer who has opened a restaurant in Shanghai and worked as a vice mayor of Chengdu. In Li Jieren’s article "Talking about the basic necessities of life in Chinese-1947 and 1948", there is such a passage: "Eating beef omasum hotpot with buffalo originated in Jiangbei, on the other side of Chongqing. At first, the general retail dealer bought buffalo viscera, washed it and boiled it, then cut the liver and stomach into small pieces, put a mud stove on the shoulder, and put a griddle iron basin on the stove. The pot was turned upside down and boiled with a spicy, hemp and salty marinade. So people on the bridge by the river, friends who generally sell labor, and beggars who want to eat meat after earning a few words, gathered around the burden and benefited. It is not only economical, but also can increase the quantity of calories. I haven’t known it for many years, and it was all noticed by people above the class of Little Bourgeois. It was not until 21 or 22 years of the Republic of China that a small restaurant in Chongqing Commercial Street ennobled him and moved him from the head to the table.

Conjecture 2: the origin theory of "water eight blocks"On the streets of Chongqing, there is also a hot pot restaurant named "Shuibakuai", which is probably a belief in this school of theory. Some people think that at the end of the Qing Dynasty and the beginning of the Republic of China, there was a popular way to eat "eight pieces of water" on the docks and streets of Chongqing. On the roadside food stall, there are small dishes filled with all kinds of beef offal, and there is a mud stove next to the stall. There is a large pot with a grid on the stove, and the pot is spicy soup base. Diners pick raw slices from the plates to burn food, and then count the plates to pay for it.

Conjecture 3: the origin theory of Zaifang Street.Zaifang Street, next to Chuandao turn, is under the existing Shibanpo Yangtze River Bridge. This is the slaughter place of cattle and sheep in Chongqing in those days. According to this view, Chongqing hot pot originated in this place around the fifteenth year of the Republic of China (1926). Because after the cattle were slaughtered here, no one wanted the beef offal, so some people collected these beef offal that nobody cared about and opened a spicy hot pot restaurant.

Conjecture 4: the theory of the origin of boatmen.This statement is very common, and many hot pot owners have told me so. Chongqing is a big wharf with many boatmen. For the convenience of eating, at the bow of the boat and by the river, boatmen casually set up a pot to pick up or buy some beef offal that was not needed in the slaughterhouse. When the spicy soup was cooked, the hot pot was born.

Guess 5: the theory of the origin of miscellaneous vegetables.This origin, because it is not clean, even a little disgusting, is basically not mentioned in all hot pot restaurants now. Why? Because, miscellaneous vegetables are the leftovers in the restaurant before. Every day, especially in larger restaurants, a lot of leftovers are accumulated. Restaurants gather these leftovers together, wholesale them to vendors, buy them back from vendors, pack them in cauldrons, and sell them to poor people passing by on the side of the pier. A spoonful of miscellaneous vegetables and a bowl of "Maoertou" dry rice is a meal. There are also some poor families who buy some to go home and eat them as food. There is some oil and water in the miscellaneous vegetables, which can also be regarded as a beating in sumptuous food.

Leftovers naturally don’t taste good. Small vendors engaged in miscellaneous vegetables business came up with a clever idea, adding a lot of sea pepper and pepper. Under the hot marijuana, all the strange smells were suppressed. The poor people who bought home, after eating miscellaneous vegetables, will continue to cook vegetables with the remaining spicy soup base-hot pot was born. Miscellaneous vegetables, this name is not nice, so people gave it a nice name, called "Naolong Palace".

Miscellaneous vegetables are found all over the country. Beijing is called "combined vegetables", which is actually leftovers. During the Anti-Japanese War, the beggar boss of Marble Stone married his daughter, and he did a lot of things in the open air by the Marble Stone River. All the banquets that beggars come to eat are "making trouble with the Dragon Palace".

It is said that in the past, the income from selling miscellaneous vegetables in restaurants was not the boss’s, but the private account of all the guys.

Because the grade of miscellaneous vegetables is very low, Chongqing people swear and often use the word "miscellaneous vegetables": you miscellaneous vegetables! Here, miscellaneous vegetables are basically equivalent to the "three abuses" in Mandarin.

Which conjecture is more correct?

These five conjectures about the origin of hot pot have been flying around for many years in the smell of hot pot over Chongqing, and no one can explain themselves.

There are different opinions, which makes the owners of Chongqing Hot Pot Restaurant unable to recognize their ancestors. Some bosses, who can’t wait, just find an ancestor at random and hang it on the wall for three incense sticks in the morning and evening. If you are bold, simply claim that I am the first one. Why don’t you find another one to come out?

This article dare not say the final conclusion, just trying to get as close to the truth as possible.

According to the basic logic theorem, if there are two different descriptions of the same object, there must be a false one. Besides, there are five different descriptions. What should we do? I suggest we try the "exclusion method" first.

Personally, the most popular "the origin of boatmen" is the first of these five conjectures to be eliminated.

There are docks all over the Chuanjiang River and boatmen all over the Yangtze River. If hot pot originated from boatmen, why is it unique to Chongqing? Is it possible that the boatmen in Yibin, Luzhou, Fuling and Wanxian will not eat? Are they all that stupid? I don’t know if I want to use spicy soup to cook vegetables. They don’t kill cattle there? There will be no abandoned beef offal?

Therefore, if the boatman origin theory holds, then the origin of Chongqing hot pot is not Chongqing, but the whole Sichuan River. Chongqing hot pot will be sadly renamed Chuanjiang hot pot-where there are no boatmen in Chuanjiang? Where is Chuanjiang spicy? Where do boatmen not eat? Where is the dock free of beef offal?

Besides, why should only a boatman set up a pot and burn food with spicy soup base? Will beggars? Will the porters on the dock? I think farmers are also very likely. In the field, a pot and a dish can be very hot. Can we also have a theory of the origin of farmers, porters and beggars?

In fact, before Chongqing hot pot, there was no record of spicy hot pot in Sichuan. Therefore, the origin of Chongqing hot pot must be found in the history of Chongqing, not on the Chuanjiang River. That is really the wrong dock.

Some people take a photo of a boatman eating hot pot in the late Qing Dynasty as an ironclad proof that hot pot originated from boatmen. Oh, my god, this photo can only prove that they are eating hot pot, and it can only prove that there was a hot pot in the late Qing Dynasty. Who eats hot pot? He invented this hot pot? This logic is too powerful. I still eat hot pot every week. Why didn’t you say that hot pot was invented by me?

This theory of origin has no facts and no logical support.

The second thing to be eliminated is "eight pieces of water".

It is a mistake as the name implies to say that eight pieces of water originated from hot pot. Hot pot is what you eat in the spicy soup base! It has never been "eight pieces of water".

The book "Cuisine of Sichuan Cuisine", published in 1980s, has an entry of "eight pieces of water". Eight pieces of water is a kind of cold chicken. Use a male chick, boil it in boiling water a little, and cut it off. Then remove the chicken head, chicken feet and chicken wings, just cut the chicken body in half and then in half, cut it into eight pieces, and then use the oblique knife method to connect the bones with the meat and slice it into pieces of uniform size. Put it in a big basin, add red oil and other seasonings and mix well.

This is a folk dish, which used to belong to the category of "Tian Xi".

The book Sichuan Cuisine is very authoritative in the industry. When this book was written, many chefs and gourmets in the Republic of China were still alive, and many dishes in the book were handed down by these masters, so they didn’t talk nonsense.

I used to cook chicken, as if I liked the word "eight pieces", and there is a famous dish called "eight pieces of chicken with fish flavor". In short, it is to cut the chicken into pieces, like fried crispy meat, coat it with egg powder, fry it twice in oil pan, fry it until crispy, and then pour in fish sauce. In fact, it is not necessary to cut only eight pieces, but to use the expression "one chicken cuts eight pieces" to describe that this chicken piece should not be too small, otherwise it will not be enough to chew.

Therefore, eight pieces of water and hot pot have nothing to do with fart. It’s all a lie, plus a rumor.

There are three theories of origin: Li Jieren’s theory of the origin of Jiangbei, others’ theory of the origin of Zhafang Street, and the theory of the origin of miscellaneous vegetables that is not so tall.

Of these three origins, the first two are about the place of origin. Only the theory of the origin of miscellaneous vegetables is about the origin of the vegetables themselves.

It doesn’t matter where the place of origin is in Chongqing. No one can come up with hard evidence to prove that the hot pot came from my Dajiang North, or from my Dazaifang Street. The existing ones are all isolated evidence or legends. What we need to analyze is the time interval when hot pot was born in Chongqing and its evolution process.

Many famous dishes, especially hot pot, a special diet form, are unlikely to be so-and-so geniuses. Most of the whimsy after waking up goes through an evolutionary process and then gradually takes shape.

Evolution process of hot pot

This is also my guess, not necessarily right. Readers are welcome to criticize and correct me.

In the mid-Qing Dynasty, peppers came to the table in Sichuan.

But the premise of hot pot is not only pepper and pepper, but also oil and water. Scoop a spoonful of water to ensure that you can’t cook the taste of hot pot. If you have to cook it, it is estimated that no one will eat it. In those days, regular restaurants, no matter how big or small, could not invent the form of hot pot-in those days, spicy food was very off the table and was the food of the poor.

Slowly, by the end of the Qing dynasty, some small restaurants began to appear spicy dishes. This can be seen from the book "Chengdu Overview" published in 1908. At that time, less than 10% of the dishes in Chengdu restaurants were spicy. This is a very strange phenomenon. Restaurants refuse spicy food, but it has long been popular among the people-I have a book "Zhong Fu Lu" written by Zeng Yi, a beautiful woman in Chengdu during the Xianfeng period, which contains her family’s method of making watercress.

Then, the combination of miscellaneous vegetables and spicy food should be the earliest form of hot pot.

Miscellaneous vegetables and peppers all come from grass roots. After the combination of the two, you can use pepper to suppress the strange smell of miscellaneous vegetables. More importantly, the combination of oil and water in miscellaneous vegetables and pepper and pepper is the necessary condition for the birth of hot pot-we have to talk about logic, right?

Since the miscellaneous vegetables with pepper and pepper are not difficult to eat, can we not waste the soup after eating the miscellaneous vegetables? Something hot, isn’t it delicious and economical? If you add a little unwanted beef offal, the oil and water will increase and the taste will be good-well, in this way, the hot pot will stumble all the way to us.

The boss who started making hot pot is probably the one who sold miscellaneous vegetables.

To establish this form of hot pot, several conditions must be met: first, the bottom soup should have oil and water; Second, pepper and pepper have widely entered the people; Third, there are cheap sources of goods, such as beef offal and pig offal; Fourth, there are a large number of customers-friends who are so poor.

Unfortunately, Chongqing meets all these four conditions.

Miscellaneous vegetables have oil and water; Pepper was already popular in the late Qing Dynasty, which is recorded in writing. Chongqing Zaifang Street is not far from the pier, and the purchase channel of beef offal is very convenient; Plus Chongqing Grand Pier, the rich are a dime a dozen, and the poor are more than a dime a dozen.

Hot pot, in this way, is separated from miscellaneous vegetables and becomes an independent diet form-Heroes don’t ask about their origins, but delicious food is king!Chongqing hot pot, which was born at the grassroots level, set off in this way and headed for its sea of stars!

At the beginning, hot pot was probably also a tourist stall, and then some tourist stalls with good business were fixed as sitting stalls.

Early chafing dish, I believe, is not only available in Chongqing, but all places that meet these four conditions are likely to develop this form of chafing dish independently or by reference. It’s just that in my big Chongqing, this hot pot is booming.

In the early 1920s, there was a "worthwhile" pub in Shuigou Street, jiangbei town. The location of this pub is relatively partial. In the past, it mainly sold "cold single bowls", that is, loose wine with a little peanuts and dried beans, and the business was not good. Later, the hot pot business was added, and the business was good.

However, this is not the earliest hot pot in Chongqing. Because, at this time, there are already many open-air hot pot stalls on the roadside of Chaotianmen and other docks. Moreover, this "worthwhile" is definitely not the first, but other restaurants that learn from cats and tigers.

At that time, the hot pot stalls were sloppy. A mud stove, an iron pot, and inside the iron pot, there is a tic-tac-toe nine-square grid that is still in use. Next to the pot, there is a chopping board. The main dishes on the chopping board are: beef oil residue, beef heart, beef liver, large intestine and leg meat. Vegetarian dishes are wrapped in white, green onions and garlic seedlings, and there are also dried rice and dried rice.

The boss stood behind the chopping board with a kitchen knife in his hand. Beef oil residue and other meat dishes have been cut into large chunks, and diners (basically laborers) feed by the chunks, while the boss helps diners change the designated meat dishes into knives and cut them into small pieces. Everyone eats their own food-please note that there is no hairy belly at this time. As for vegetarian dishes, they are charged by the "handful", and the boss pays how much for each handful.

In the early days, except for the docks at Chaotianmen, most of the hot pot stalls in the city were concentrated under the eaves of the street at Jiaochangkou, and their management methods were the same as those on the docks. Jiaochangkou was a slum in Chongqing. The rich people in Chongqing are mostly in Duyou Street (now Jie Fangbei) not far away.

Compared with the most famous hot pot stall in the market, the boss nicknamed it "Li Maomi". When he counted the diners, he used the old small copper coins. Small copper coins are also called cents, so they got this nickname. Li Maomi is good at business. Every morning, he collects lithograph posters of various theaters on that day and sticks them on the wall next to the stall, where diners can talk while eating. This hot pot stall was destroyed by war during the Anti-Japanese War.

Chongqing hot pot is so famous that it has become a representative of spicy hot pot. This is related to the location of Chongqing. Before the Anti-Japanese War, Chongqing was the largest water wharf, the largest commercial city and the largest industrial city in southwest China (although there were few industries), and there were many poor people, so this hot pot stall correspondingly increased, and its reputation gradually increased.

Chongqing hot pot became famous all over the country, which really depended on the Anti-Japanese War.

Almost all the famous hot pot restaurants I can find are famous during the Anti-Japanese War. These hot pot restaurants are: Yunlong Garden, Luminous Cup and Shuyuan in Linjiangmen; 141 of Mihua Street (now Bayi Road) (later merged with Yunlong Garden in 141); Do not return if you are not drunk on May 4th Road; The "Han Palace Maodu Hotpot" in the Spiritual Fortress (now Jie Fangbei) … and so on.

Can’t help but say a digression. Now some hot pot restaurants like to recognize their ancestors. Of course, not only Chongqing, but also many places in China have this bad habit: find a brand that has disappeared from history, and then run out to recognize their ancestors and say that they are descendants. I’m sorry, please show me the chain of evidence, or I won’t recognize your grandson who was born. Especially those who call themselves the "first family" are even more absurd. Hot pot is a gradually formed diet, and it is impossible to prove who is the first one!

Get down to business. Hot pot stalls have appeared, can the hot pot restaurant be far behind? However, who actually moved the hot pot from the roadside stall into the small restaurant has no test now.

The hot pot at that time was completely different from now. Mr. Ma Zhitu once recalled the scene when he was eating hot pot in Chongqing: "Just lowering the table, sitting on a high stool, stepping on the table, shirtless, eating and drinking loudly, is really called eating Chongqing hot pot." -At that time, hot pot, put a small mud stove on the table, a small pot on the stove, or one person, or several people, sit around and eat.

The stove is on the table, and diners have to sit on high stools. The trick of burying hot pot in the table will take a long time to appear.

Ma Shitu, a famous person, ate a lot of hot pot in Chongqing and wrote a lot about it. Slowly, the fame of Chongqing hot pot spread far and wide.

 Finally, let’s guess againThe birth path of hot pot(The following is pure conjecture. If there is anything wrong, please criticize.)

At the end of the Qing Dynasty, with the popularization of peppers, miscellaneous vegetables, peppers and prickly ash were finally happily combined.

Then, the hot pot is separated from the miscellaneous vegetables. After several years, from 1900 to 1910, people began to forget the relationship between hot pot and miscellaneous vegetables. At this time, as an independent diet, hot pot was accepted by people.

Then (1910-1920), hot pot booths appeared, that is, the predecessors who carried the burden of hot pot and wandered around.

Some hot pot stalls with good business have been fixed and become hot pot stalls. After another, more people joined the team of hot pot stalls. However, the hot pot fixed stall and the traveling stall are likely to coexist, just as the traveling stall and the fixed stall in Dandan Noodles have coexisted for a long time.

Around 1920, the business of hot pot stalls became better and better. The population of Greater Chongqing is also increasing. Many high-end people not only like the heavy taste of hot pot, but also don’t want to put down their bodies, go to the roadside and rummage around in a pot with people who are working hard. At this time, some restaurants began to put hot pot on the table one after another.sideline in.

The professional hot pot restaurant appeared later, and it is estimated that it will not appear until around 1930.

The final shape, development and popularity of Chongqing hot pot in the whole country was during the Anti-Japanese War.

Original title: the origin of Chongqing hot pot! The truth may surprise you …

Exploded, the domestic spy war is so delicious!

Domestic dramas are full of Sao operations.

It is even said that some pictures are flushed even when Uncle Ba looks at them.

Appears in the form of a full-screen mosaic.

She, the people’s female teacher.

Wearing a white gauze skirt and cutting short hair, accompanied by dim light, tutoring students and seriously teaching the appearance of ancient Chinese can be called a teacher.

The child’s Chinese score rose by 24 points.

Other departments should catch up again

You can touch the threshold of key high schools.

Teacher model?

At the end of the night, she wore heavy makeup and opened a room with the parents of the students, and she was honest with each other.

He, the taxi driver.

Listening to the guest in the car boasting that he was worth more than 100 million yuan, he kept his face unchanged, but sneaked into the other person’s home to pry open the safe, and his eyes were full of RMB gold bars.

Thieves have a lot of guts?

As soon as the camera turned, he and the other party were caught in bed by the police, and the bedside was filled with "props".

What a shameful picture, what an exciting plot.

Another drama?

No, their real identities are spies.

Opponent

The story of "spy war" in peacetime.

CCTV broadcast eight sets of prime files, and as soon as it went online, it pushed back "Knife in the Snow" for two hours.

By two words:

Word of mouth.

The main characters are Double Bombing Guarantee, Guo Jingfei and Tan Zhuo.

Even the supporting roles are Yan Bingyan and Ning Li.

But judging the quality of a drama, Uncle Ba should remain fair, objective and rational.

I didn’t dare to recommend it to you until I finished sixteen episodes in one breath.

This play-

be known asMiddle-aged poor and down-and-out version of Mr. and Mrs. Smith.

 

Modern national security spy war drama is famous for its bad.

Representative work Eye of the Storm.

Douban scored 5.6 points, and Jin Sha, the director of Lei Ju’s War of Thunder, starred in Yang Mi.

Still wearing the skin of professional drama, talking about the dog blood drama of little love.

The form and slogan are mystifying, in which the logic is ill and the plot full of slots once again enters the old road of suspension.

But "Opponent" doesn’t have these problems.

On the contrary,It broke the mystery of the spy and made every effort to be true.

First, in the choice of roles.

The spy images in spy films are often omnipotent people, who are synonymous with bullets and calm, racing and chasing, and being cold-blooded and tough.

But the truth is—

Most male spies are plain-looking, so that they are not easy to be found in society.

Li Tang, played by Guo Jingfei, pretends to be a taxi driver.

Pulling up the belly is a layer of glistening meat, and there is a serious strain on the waist muscles. A bitter face all day is the image of a middle-aged man suppressed by life.

The choice of female spies usually gives priority to face value. It is undeniable that many men have weak legs when they see beautiful women, and their appearance advantages have a better chance to get information.

Ding Meixi, played by Tan Zhuo, is a very attractive teacher.

With a charming face, every man, from parents of students to researchers, fell at her feet without exception.

And then to spy technology.

Before you become a spy, you will have a wave of training.

A few key points:Reconnaissance and anti-reconnaissance ability, first aid training, attention memory training.

But the NSA doesn’t eat for nothing.

The members of the task force are capable people, have strong endurance, and drive for 27 hours without sleeping; Those with high IQ and memory will never forget anything; If you are desperate, you can handle the case without eating or sleeping; There are hackers, especially good camouflage …

It is a compulsory course for them to remain keen and skeptical at all times.

When recruiting personnel, even the tolerance of squatting will be taken into account.

There is such an episode in the play that is quite exciting-

Ding Meixi, a female spy, was almost exposed when a student accidentally cut her hand while making up lessons at her home.

Two details:

First, emergencies, no hurry.

The student’s hand was cut by a metal tool. She immediately bandaged and stopped bleeding, and took the student to get a tetanus shot at the first time.

According to the students, Mr. Ding is more powerful than that.

Before, some students in the school fell down the stairs, and the bones were exposed. The scene was terrible. The principal was scared at that time, but Mr. Ding took his time to connect the students’ hands and helped them to the hospital.

Second, super memory, beyond ordinary people.

After handling the students’ hands, Mr. Ding received calls from other students’ parents.

Parents said that the schoolbag was left at Teacher Ding’s house. Even in such a hurry at that time, she was still very sure about the size and shape of the schoolbag, and she was sure that the schoolbag was definitely taken away from her house.

Even, she remembers the belongings of dozens of students in the class.

Although Teacher Ding explained that students’ affairs are more important, these two points still attracted the attention of parents of students and the head of the task force of the Ministry of National Security.

Not stupid confrontation, confrontation between eyes and words, uncle pai didn’t dare to blink easily when he looked at it.

But "Opponent" is about more than that.

Pull open the mysterious veil of spies, and there is another layer of hidden sorrow.

 

Spies are not so easy to be.

Li Tang and Ding Meixi are such a disguised couple.

Seventeen years ago, they accepted the task and came to Xiamen, with a unified code name of Phoenix.

In the past 17 years, they have been married and given birth to daughters like ordinary couples. For more than ten years, from sweet love to daily necessities, people are still facing a midlife crisis when they reach middle age.

But the actual spy’s life is poor and humbled.

This couple of spies is the worst in history:

Worried that the money is not enough to spend, life is tight, children can’t keep up with their physical strength when they are rebellious, and they are still under great psychological pressure …

Those so-called cool settings of wearing sunglasses and leather clothes are just the beautification of film and television works.

As a matter of fact.

None of the good things have been touched, but the troubles have come one after another.

At the beginning, they were faced with the problem of crushing them:

The chickens ran away from the joint, and they were also taken away with their wages and expenses as spies.

The already difficult life is worse.

Li Tang can only grope for clues step by step, and the first breakthrough is Yao Ji’s younger brother.

Through investigation, he determined the direction of the other party’s travel and planned to intercept it.

I thought it would be a unilateral suppression with a golden finger. As a result, I fought with each other, and I could obviously feel Li Tang’s poor physical strength.

I got a knife and three teeth were knocked out.

If it hadn’t been for the protective measures in advance, it is estimated that it would have fallen.

Old and weak, no money yet.

When the tooth fell out, I went to fill it, licking my face and asking for a discount. However, the 9000 yuan after the discount was too expensive, so I persuaded him directly.

Li Tang over the years, there is no skill, when what a big shot with deep pockets.

Usually, he is a taxi driver. He earns 400 yuan a day, and he has to pay 220 yuan to the rental company. The rest is barely enough for the daily expenses of the family.

I was given a ticket when I was on a mission, 200 at a time, and I worked for nothing for a day.

Ding Meixi has a hard time there, too.

Constantly dealing with various men to sell sex and get information, and often encounter sexual harassment.

It is rare to make up lessons to make money as a teacher, and it is also reported by parents of students.

The money is not earned, and the two people are notorious.

A man was scolded for breaking his shoes.

As a spy, she had to have sex with people, but it made her children get involved in school and get a dirty look.

One was laughed at and cuckolded.

He can only turn a blind eye when the task requires him, and the sarcasm of others can only be swallowed by himself.

But these are small things, and they face bigger problems.

The dilemma of no choice.

On the one hand, it is the task assigned by the organization, threatening you with your own life, and you can’t escape if you want to escape.

Only success, not failure.

On the one hand, it is the attention of the Ministry of National Security. Once they start to suspect, they are in a state of being caught at any time.

Strictly guard against death and wait every day.

For a spy.

Further is death, take a step back or die.

They have no way out.

 

Domestic spy war dramas used to have a fixed mode of cool drama-the focus of the crowd, and the distinction between good and evil.

After watching too much, the audience also has a stereotype.

But the best thing about "Opponent" is that it tells the real spy life.

This is not a cool play.

The key performance isThe tragic life and hopeless future of spies.

Take Li Tang Ding Meixi and his wife in the play for example.

On the one hand, fight with your life.

Before each mission, they will do a full set of protective equipment, and it is common to use knives and guns. This is the experience that they have learned after many injuries.

On the one hand, worry about daily necessities.

Every day, apart from quarreling or quarreling, for money and for life, it seems that only in this way can people vent in middle age.

"We may be the most wronged spies in history."

Ding Meixi and Li Tang go back to their rooms every day, full of complaints and complaints.

No money, no status, even can’t go home.

Even after more than ten years in a foreign land, even if they go back, they don’t know how to live. The authorities have changed several times, and they don’t know how to take the tram.

But the grievances of two people are nothing. After all, even death is not so terrible for them.

It’s like their joint is online, chicken.

I have been a spy for a longer time than Li Tang and Ding Meixi. From young to old, I began to gasp after eating a few jiaozi, and I was afraid to get married and have children, for fear that my identity would drag others down in the future.

I live worse than a watchdog, and I have been threatened to be a traitor.

After nearly twenty years of torture, death may be the relief.

The only thing that holds them back is pretending to be a daughter born to a husband and wife, and that is their responsibility.

Beating is pro-scolding and love. Although Ding Meixi scolds her daughter for being ignorant, smoking and falling in love every day, every sentence reveals love.

They are afraid of revenge by spy organizations, and they are afraid that their daughters will see their parents arrested.

The spy in the play has a touch of sadness.

Especially Ding Meixi.

From the first class of spy training, you will be insulted by rape.

Seduction, bribery and threats are the necessary abilities of female spies.

Even Ding Meixi, who is married and has children, feels the physical and mental destruction all the time. Every time she has sex with a man to get information, she will brush her teeth and go home.

She hates this kind of herself and can’t stand this kind of life, but it’s not her choice.

And this is not only in film and television dramas.

"Opponent" is the most typical of reality, and it is also experiencing the same dilemma as the real spy.

You can’t get much money, but you have to fight with your life.

Maybe there are spies around you and me.

On the surface, they are like ordinary people, but in fact they are buried in a dark corner and will never see the sun.

Uncle Ba made a bold guess-

What the drama really wants to express may be to inform spies and people who may be rebelled.

If you get lost, you will find your way back.

 

Nanjing Smart Factory’s first batch of production cars were shipped off the assembly line on a large scale.

[Global Network Auto Report] Recently, Deep Blue S7 was officially launched in Nanjing Smart Factory, and the first batch of production models are also being shipped off the assembly line on a large scale.

As the key to Changan Automobile’s comprehensive transformation of new energy, Deep Blue brand has invested a lot of money and efforts in product research and development and core technologies. For example, Nanjing Smart Factory, which locates a brand-new intelligent personalized customization demonstration factory for new energy, integrates flexible, intelligent, automated, digital and efficient production technologies. As the first medium-sized SUV launched by Deep Blue Auto, Deep Blue S7 has been highly anticipated since its birth, and Nanjing Smart Factory is used to produce Deep Blue S7, which is to provide strong intellectual quality for Deep Blue S7.

Nanjing Smart Factory has a planned annual production capacity of 200,000 vehicles, including five workshops: stamping workshop, body workshop, painting workshop, assembly workshop and battery workshop. It has four characteristics: brand-new energy, intelligence, personalized customization and zero carbon. Because of the empowerment of Nanjing Smart Factory, Deep Blue S7 has excellent performance in product quality. Nanjing Smart Factory has set up 11 quality walls from raw materials of parts to delivery of whole vehicles to ensure that every car is delivered with high quality.

The four technological highlights of stamping, welding, painting and final assembly have a number of initial technologies.

The automatic boxing system in stamping workshop is the first in the industry, and stamping realizes full automation of boxing, that is, all parts are fully automatic boxing. Using 6 2D cameras to locate parts, guiding 6 robots to grab workpieces, and then matching 2 3D cameras to accurately locate containers, is equivalent to providing robots with a pair of eyes, which can guide robots to pack boxes and then replace labor to realize full automation of packing;

On-line inspection technology for solder joints is the first in the welding industry. The automatic counting and recording of solder joints (2,241 self-made solder joints, self-inspection of 1,300+self-made solder joints, the overall self-inspection rate of solder joints is 60%, and the quality problems such as missing welding, missing welding, dislocation, distortion and splash are avoided), the gluing quality (the coverage rate of automatic gluing and visual inspection is over 90%) are detected online and monitored in real time to ensure the quality of the car.

Painting strictly follows the engineering control requirements of 10 micron clean workshop, and the automation rate is as high as 70%, leading the industry. At the same time, in order to realize the paint color of extremely bright yellow, bright black and cool white, a two-color paint coating spraying process with solid primer and pearlescent paint layer was innovatively developed.

The assembly workshop pursues the best overall logistics efficiency from the top-level design, adopts intelligent logistics equipment to the greatest extent, and realizes the unmanned logistics process. Through the implementation of logistics management, warehousing management, manufacturing management and other systems, combined with the application of new technologies such as magazine stereo library and robot automatic loading and unloading, the logistics automation rate is as high as 62%, reaching the first place in Chang ‘an system and leading the industry.

In addition to the manufacturing strength behind the deep blue S7 quality, Nanjing Smart Factory has four advantages: brand-new energy, intelligence, personalized customization and net zero carbon. As a brand new energy factory, Nanjing Smart Factory can develop new energy vehicles such as pure electric vehicles and extended range vehicles. For the first time, the self-developed CTP flexible lithium battery PACK workshop was laid out, which has the ability to develop the whole new energy industry chain from design to manufacturing.

The appearance of Deep Blue S7 continues the family design language, including electric hidden door handle, double-layer laminated frameless door, low-lying posture and 21-inch large wheels. The whole appearance presents a young and fashionable style.

In the interior, the new car is covered with a large area of soft, full of texture, and the central control adopts a 15.6-inch sunflower central control screen, which can automatically rotate 15 degrees to the left or right according to the position of the occupant. The front row is equipped with the only double zero gravity massage seat for models within 500,000, which supports 14-way electric adjustment, 8-point massage function and can lie flat at 120. The position of the co-pilot sun visor is also equipped with a 12.3-inch entertainment display screen. With the suspended sound island +DEEPAL 14 speaker, the sense of technology and quality in the future is full.

The power part of the new car is equipped with Chang ‘an Force technology, which provides extended range and pure electric versions. The extended range version of CLTC has a pure electric battery life of 200km, the comprehensive battery life of CLTC can reach 1120km, and the pure electric version has a maximum battery life of 620km.

Write at the end:

As the key to Changan Automobile’s comprehensive transformation of new energy, Deep Blue brand has shown great potential in both manufacturing technology and product strength. Deep blue S7, as one of the representative works of deep blue brand R&D strength and technological breakthrough, has brought you many surprises. The large-scale off-line shipment of the first batch of mass-produced Deep Blue S7 also updated the countdown to the launch of new cars, and Deep Blue S7 came.

7 points to raise 3 points to repair an article to understand the depth of oil, not afraid of being fooled.

  Engine oil is the blood of the engine, which has the functions of lubrication, cooling, wear reduction, cleaning, sealing and rust prevention. A truly suitable engine oil for car engines can not only fully protect the engine, but also bring excellent driving experience and more economical fuel consumption performance.

  How to choose the engine oil in the end? I believe many car owners don’t understand and are too lazy to think about it. When the car is being maintained, it will be handed over directly to the 4S shop. But is the engine oil in 4S shop really worth that much money? The more expensive the oil recommended by 4S shop, the better? After the warranty comes out in three to five years, will you still go to the 4S shop for maintenance?

  Therefore, how to choose an engine oil that really suits your car should be what every car owner needs to know. If you want your car to stay with you for a longer time, you need 7 points for maintenance and 3 points for repair.

  In this article, we introduce how to choose a really suitable engine oil from the perspective of popular science for engines with different car series, different displacements, different powers and even different car ages. When recommending more expensive engine oil in 4S shop, we have reason to refuse or indeed accept the engine better.

7 points to raise 3 points to repair an article to understand the depth of oil, not afraid of being fooled.

  Many engine oil brands are marked with two important parameters in the most conspicuous place of the outer packaging: SAE engine oil viscosity standard and API engine oil grade standard. The former, such as 0W-40, 0W-30, 5W-40, 10W-60, etc., indicate the different viscosities of engine oil at low temperature and high temperature. The lower the number before "W", the better the low-temperature fluidity and the smoother the low-temperature cold start. The higher the number after "-",the higher the viscosity at high temperature, and the better the lubricity and sealing performance. At present, the widely used API grade of engine oil ranges from SL to SN PLUS, and the latest API grade has been developed to SP in 2020. From "SA" to "SP", with each increment of a letter, the performance of the engine oil will be better than the previous one, and there will be more additives in the engine oil to protect the engine. It can be clearly seen from the above table that the true meaning of oil viscosity.

Fluidity of engine oils with different SAE grades at 0℃

  0W is easy to understand. In the northern region where the temperature is very low, we can directly choose 0W or 5W engine oil, so we don’t have to worry too much. However, the kinematic viscosity of engine oil at 100℃ needs our careful choice. For most gasoline and diesel vehicles, when the engine water temperature reaches the normal 85-95℃, the engine oil temperature is in the range of 90-110℃, and it will not change greatly with the outside temperature. Therefore, the choice of 100℃ kinematic viscosity of engine oil only depends on the high-temperature viscosity requirements of engines of brand cars, regardless of the external environment temperature. To put it more bluntly, different engines should choose different engine oils with kinematic viscosity of 100℃, that is, the number after "-".

  The higher this number, such as XW-405060′ s 100℃ high kinematic viscosity engine oil (hereinafter referred to as high viscosity engine oil), the greater the viscosity at high temperature, the thicker the oil film, the stronger the shear resistance, and the better the lubricity. The better the sealing between piston and cylinder wall, the better the dynamic response when driving at high speed. At the same time, it can also suppress the noise of the engine more effectively, but compared with waste oil. On the contrary, the smaller this number is, such as the 100℃ low kinematic viscosity engine oil of XW-3020168 (hereinafter referred to as "low viscosity engine oil"), it is easier to reach the normal working temperature at low temperature, and it is more fluid and fuel-efficient at high temperature. However, the oil film is easy to tear and lose its lubrication function when driving fiercely for a long time. A Japanese sports car owner used ordinary 20 low-viscosity engine oil to get off the track, which led to the engine size tile burning cylinder pulling to overhaul the engine. In addition, due to the relatively poor sealing performance of low-viscosity engine oil, the cylinder pressure couple releases pressure, which shows that when running at high speed, the engine speed rises but the speed does not rise, and the engine noise is relatively obvious. In order to solve these problems of low viscosity engine oil, it is often necessary to add more anti-wear and anti-wear additives, so the price is relatively expensive. This also reminds everyone that when choosing low viscosity engine oil, you must choose the engine oil of the regular big factory brand.

Tragic example of burning tiles

  In addition, I have to say that the API standard can’t prove the quality of this oil. All oil manufacturers prepare their own oil according to API standards, and they can generally pass as long as they are willing to spend money to do bench tests in the United States. It’s like taking an exam. If you pass the exam with a score of 60 out of 100, you can get a "diploma". As long as it is not fake engine oil, engine oil meeting API SL, SM, SN, SN PLUS and SP levels will not cause damage to the engine, but it may not be suitable for your car. A really good engine oil, sometimes the API level is not high, let’s talk about it in detail below.

  If the API standard in the United States is a passing line, then the ACEA standard in Europe is a good line with a score above 75. The European ACEA standard requires higher and more stringent quality of engine oil, which has stricter requirements for engine testing than API, such as adding a more stringent 150℃ HTHS high temperature shear test. Engine oil with API certification but no ACEA certification is not allowed to be sold in Europe.

  For European cars, especially European turbocharged engines, there are strict requirements for the high temperature shear value of HTHS at 150℃, which needs to reach above 3.5. Different from the idea that Atkinson cycle and hybrid technology are widely used in Japan to improve the thermal efficiency, the European system prefers to use turbocharging to improve the thermal efficiency of the engine, which also passively improves the working temperature of the engine, so it requires higher HTHS values. The higher the HTSH value, the better the stability of the oil film at high temperature, and it is not easy to be torn, thus avoiding direct friction between metals (boundary friction).

7 points to raise 3 points to repair an article to understand the depth of oil, not afraid of being fooled.

  ACEA contains the A/B/C/E standard, which represents the requirements of gasoline and diesel engines for engine oil. For most domestic gasoline engines, we only need to look at the A standard. As shown in the above figure, ACEA A3/B3, we only need to look at A3. The HTHS corresponding to A3 is above 3.5, which is suitable for most European turbocharged engines. Due to the increasingly stringent environmental protection requirements and the development trend of low viscosity engine oil, the highest A5 HTHS at present is between 2.9 and 3.5, and the SAE viscosity is roughly XW-20/30.

  Write here and make a small summary. American API standards are universal. Just look at them, and don’t even use them as an important reference. If the API standard font on an oil bottle is particularly large and eye-catching, it means that it is hiding something. When choosing engine oil, you are advised to look at the European ACEA standard. The requirements of Japanese and American departments for HTHS are between 2.6 and 3.5, the corresponding ACEA standard is A5, the requirements of European departments for HTHS are above 3.5, and the corresponding AECA standard is A3.

  If you want to know more about the ACEA 2016 standard, you can download the PDF document yourself:

  https://www.acea.be/news/article/acea-oil-sequences-2016-august-2018-update

  However, remembering ACEA A5 and A3 is not enough.

  ACEA engine oil standard has been very strict. If the engine oil that meets this standard can score 75 points, the engine oil that meets the engine oil standard issued by the main engine factory itself can get excellent results of more than 85 points. Therefore, oil manufacturers are actually very tired. They not only have to spend money to make API standards and sell them to most parts of the world, but also spend money to do ACEA tests and sell them to Europe. It will take more money and time if they want to get the certification from the OEM.

  From the above picture, we can see three major certifications: European ACEA A3/B4; American API sn/sm; Main engine plants MB-Approval 229.5/229.3 (Mercedes-Benz certification), VW 502 00/505 00 (Volkswagen certification) and Porsche A40 (Porsche) certification. The engine oil certified by the main engine factory can be safely and boldly selected. Each OEM’s global official website has its own certified oil PDF document, which can be searched. The following one is from Mercedes-Benz:

  https://bevo.mercedes-benz.com/bevolistenmain.php? navigation_path=bevolisten&language_id=0&blatt=229.5&content_action=show&mark=229.5&suchbegriff=229.5#close

Examples of Mercedes-Benz certified engine oil
Examples of Mercedes-Benz certified engine oil

  So there are so many oils that meet the OEM certification, how should we choose? Read the instructions first! For example, the 2017 W213 Mercedes-Benz E-Class uses the M274 engine, and the instruction manual reads: Choose engine oil products that meet the MB229.5 standard. Under the premise of meeting this standard, we can choose different viscosity oils. For example, Mobil’s 0W-30 and 0W40 both meet this standard. If you want to save more fuel, you can choose 0W-30 engine oil, but low viscosity engine oil can’t suppress noise well, and the engine noise will increase. If you want quietness and dynamic response at high speed, you can choose 0W-40 engine oil, but you may use waste oil in your daily car. The main purpose of using the car is to travel in the city or to run long distances frequently. At this time, you need to think it over. For most family cars, I suggest that the thinner the SAE viscosity, the better, on the basis of meeting the engine oil standard.

  In addition, many Volkswagen car owners asked if the oil products they bought were not certified by the public, but only the certification of Mercedes-Benz could be used. It can be definitely answered that except for super-running, the engine oil that meets the certification of Mercedes-Benz MB229.5 can be used in European cars, and the engine oil certification of Mercedes-Benz is the most stringent for European cars (except super-running). Why do you say that besides super-running? The engine speed of supercar or sports car is too high and the working environment is harsh. It is best to use the engine oil certified by supercar main engine factory. For example, Ferrari’s certified oil is Shell.

  But I haven’t finished yet. The engine oil certified by the main engine factory can do the most comprehensive protection for the engine, but all-round development doesn’t mean all-round Excellence. We can also choose better engine oil according to our own demands for driving experience, quietness, fuel economy, cold start, and even playing off the track.

  As mentioned at the beginning, API SN standard engine oil does not represent good engine oil. Because it can’t represent all the characteristics and parameters of engine oil, even if they are all called synthetic engine oil, their performances are very different with different base oils. Poly (α-olefin) synthetic oil (PAO for short) is produced into high-purity base oil by natural gas hydrogenation polymerization. It has good low-temperature fluidity and oxidation resistance, and is an ideal base oil for preparing high-grade and special lubricating oil.

7 points to raise 3 points to repair an article to understand the depth of oil, not afraid of being fooled.

  However, the API grade of engine oil with high PAO content is not high. This is why, as mentioned at the beginning, API SN grade engine oil is not the best engine oil. For example, the domestic Mobil FS 0W-30 API is SL, and the top technology of Limo engine oil flagship product, 0W-30 API, is SM. In fact, API SN and SN PLUS grades mainly improve the requirements of environmental protection and low-speed early combustion of engine oil, and have little to do with lubricity.

7 points to raise 3 points to repair an article to understand the depth of oil, not afraid of being fooled.

  Besides PAO base oil, there are Ester oil base oils. Ester base oils have excellent lubricity, especially whale ester, lard modified oil, etc., but their low-temperature fluidity is poor and they are easy to be oxidized. At the same time, in view of animal protection and cost, the current ester base oils are all artificially synthesized. Ester base oil can be used as an additive of PAO base oil to improve its lubrication performance. Pure ester oil, such as NUTEC in Japan, is a favorite product of many street car racing enthusiasts.

  As we all know, there are mineral oil, semi-synthetic oil and fully synthetic oil, and the replacement mileage is 5000 km, 7500 km and 10000 km respectively, but the replacement mileage is not fixed according to different car scenes. If you often run high-speed, the whole synthetic engine oil can be extended to 15,000 kilometers for oil change. If there are frequent traffic jams or ethanol gasoline is used, it is best to change it every 8,500 kilometers in synthetic engine oil.

  Why do you need to change the oil in advance when using ethanol gasoline? Let’s talk about the various parameters of engine oil. These parameters can be found on various engine oil brands official website, and even some conscientious Taobao and JD.COM online stores will post various parameters of engine oil for deep engine oil players to choose from.

  Total base number (TBN)

  The higher the total base number, the stronger the acid resistance of engine oil. Engines are made of metal, both aluminum and steel are alkaline in chemical elements, so they are afraid of acid corrosion. The higher the base number of engine oil, it can neutralize the acidic substances after gasoline combustion, especially ethanol gasoline.

  40℃ viscosity

  The lower the value, the easier it is for the engine to start.

  100℃ viscosity

  The higher the value, the thicker the oil film, better protection, better sealing, better noise suppression, but more waste oil. The lower the numerical value, the better the fluidity, the thinner the oil film, the relatively poor sealing performance, the relatively poor noise suppression and more fuel saving. Different engines have different requirements for 100℃ viscosity, too low will lead to the valve timing system can not be driven because of insufficient oil pressure.

  pour point

  The lowest temperature at which the oil can flow, the lower the value, the better, and the easier the cold start.

  cloud point

  At low temperature, the oil precipitates waxy turbidity, and the lower the temperature, the less turbidity the better, which proves that the PAO content of the oil is higher.

  flash(ing) point

  The higher the temperature at which the engine oil is ignited, the better. The higher the temperature, the less likely it is for the engine to knock. At the same time, the less oil is consumed (burning oil).

  Evaporation loss

  The smaller the evaporation loss, the less oil vapor and carbon deposition in the mixture.

  Hths shear value at 150℃

  Because of different models, there is no difference between good and bad. European cars generally require more than 3.5, while Japanese cars, American cars and Korean cars require more than 2.6. The higher the value, the more stable the high-temperature oil film and the better the lubrication performance.

  The above table is the data of an original engine oil tested by Third International. When we choose engine oil, if we want to find an engine oil that is really suitable for car engines, the above parameter data needs to be well studied.

  Speaking of which, I’ll make a summary of the first paragraph of the article. Is the oil recommended by 4S shop or repair shop really worth the price? You need to have a deeper understanding of engine oil to judge, and it has been made clear from what aspects you know about engine oil. For example, the ordinary engine oil in Mercedes-Benz 4S shop is fully synthetic.Yin Mobil no.1Or brand 5W-40 such as Petronas, it is no problem to maintain the car. But the AMG engine oil recommended by the store is fully synthetic.Jin Mobil 1 0W-40, various parameters are more biased.European version of Jin Mobil No.1Although the price is more than 300 yuan, it is really better for the engine, which is worthy of trust and money for purchase.

  Finally, I collected some netizens’ oil problems as a summary of this article.

  How to choose engine oil for different cars?

  For Japanese cars, the engine work is precise, the tolerance value of thermal expansion and contraction is small, and the working temperature of Japanese engines is generally low, so it is basically recommended to use 0W-20 viscosity engine oil. In Japan, even 0W-8 engine oil has been used, which is as thin as water at room temperature. However, for some Japanese performance cars, it is recommended to use oil with higher viscosity. In addition, with the increasingly stringent global environmental protection requirements, low viscosity engine oil has become the future development trend. Mercedes-Benz’s latest MB229.71 oil standard can already use 0W-20 oil, but the engine meeting MB229.71 oil standard is still being tested.

  American is Korean, and engine oil with viscosity of 0W-30 is basically selected.

  At present, the majority of German engine oils are mainly 0W-40 engine oils and some 0W-30 engine oils with HTHS>3.5. In this respect, Audi has been at the forefront, and the specifications of some Audi models indicate that 0W-20 engine oil can be used.

  Is 5W-40 an essential oil?

  Yes. As long as it is real engine oil, 10W-60 mineral oil can’t break the engine, but choose a more suitable engine oil according to the car system. There is really no way. For example, if you run out of engine oil halfway and can’t find the right engine oil, you can use 5W-40 to temporarily solve the problem.

  What kind of oil does the small displacement turbocharged engine choose?

  Small displacement turbocharged engines are most prone to low-speed pre-combustion, that is, knocking. We should choose the engine oil that can inhibit low-speed pre-ignition, that is, API SN PLUS, and add gasoline that meets the label according to the requirements of the vehicle.

Limo engine oil

  Power Magic stunt DX1 engine oil vapor can increase the ignition point of the mixture, thus reducing the knock probability.

  What kind of oil do you choose for different car ages?

  New cars can choose low-viscosity engine oil that meets the manufacturer’s certification or meets the manufacturer’s requirements for engine oil, that is, 100℃ viscosity and HTHS value. More fuel-efficient, but also more conducive to engine hot running.

  The old car depends on the condition of the car. If the burning oil is obvious, try 10W-60 high viscosity engine oil. If there is no improvement, the engine can only be repaired.

  Can different engine oil brands be mixed?

  It is not recommended to mix different engine oil brands. Different additive formulations may lead to chemical reactions and reduce engine oil performance. Engine oils of the same brand can be mixed conservatively. For example, according to official confirmation of Mobil, different products of the same brand can be mixed. NUTEC grease engine oil in Japan even advocates consumers to buy oils with different viscosities and configure the required viscosities themselves.

  How to distinguish between true and false engine oil, and what should I do if I buy fake engine oil?

I bought the European version of Mobil FS 0W-40 online.

  Tmall, JD.COM official flagship store to buy engine oil, global purchase can buy imported engine oil, major engine oil manufacturers offline maintenance stores, there will be no fake. Personally, I prefer to buy imported engine oil online, but I must look at the reputation and evaluation of the store. The place where fake engine oil is most likely to appear is a small repair shop, so be careful. The above picture shows the European version of Jin Mobil No.1 FS 0W-40, with viscosity of 12.9 at 100℃ and HTHS 3.6 at 150℃, which is less viscous and more fuel-efficient than the engine oil provided by 4S shop, and has the certification of the main engine factory.

  In case of buying fake engine oil, there will be obvious sludge on the dipstick, and black sludge can be seen at the engine oil port. At this time, change the oil quickly, replace the Burns oil with strong cleaning ability, drive for 1000 kilometers and then change it, and repeat it for 4 times to see the effect. Never add professional cleaning oil or cleaning products for the first oil change, it is easy to clean large pieces of sludge and block the oil passage, so that the engine can not be lubricated and the shaft is burned.

  Can oil additives be added?

  After the engine oil is finished, we will talk about the advantages and disadvantages of adding engine oil additives in the next article. Stay tuned.

After robbing and killing a female taxi driver, she fled for 14 years. A criminal in Guangxi was executed.

  Hechi, January 26th, Zhongxin. com (Zhang Guangquan Su Jia) On January 26th, 2022, according to the execution order issued by the Supreme People’s Court, the Intermediate People’s Court of Hechi City identified Tan Taijian and took him to the execution ground for execution.

  The Supreme People’s Court rechecked and confirmed that the defendant Tan Taijian attempted to rob a female taxi driver. At about 17 o’clock on November 25, 2005, she went to the vicinity of the bus station in Jingxi City (formerly Jingxi County), Guangxi, and took the taxi driven by the victim Yi Momei (female, 34 years old) to the vicinity of the smelter in Debao County, Guangxi in the name of renting a car. Tan Taijian dragged Yi Momei to the back of the taxi, and Yi Momei resisted with a knife and called for help. Tan Taijian grabbed a knife and stabbed Yi Momei dozens of times in the chest, abdomen and neck, causing his heart, lungs and liver to rupture and bleed, causing hemorrhagic shock and death.

  Tan Taijian robbed Yi Momei of Motorola’s mobile phone and cash 200 yuan, and fled in his taxi. When he met the public security organ in Jiazhuan Township, Bama Yao Autonomous County, Guangxi, he set up a card for inspection. Tan Taijian handed over his fake "Xu Mouwen" driver’s license to the police for inspection, lest the body in the car be found, that is, he fled by car. At about 23: 00 on the same day, Tan Tai-jian abandoned the car and fled because of vehicle failure, and then sold the victim’s mobile phone and fled to hide under a pseudonym.

  On December 27, 2019, public security personnel arrested Tan Taijian in Lingui District, Guilin City, Guangxi Province.

  The Supreme People’s Court believes that the defendant Tan Taijian took violent measures to rob other people’s property for the purpose of illegal possession, and his behavior has constituted the crime of robbery. Tan Tai-jian thinks that robbery causes death, and the nature of the crime is bad, and the circumstances and consequences are serious, so it should be punished according to law. The facts identified in the original judgment and the review ruling of the Higher People’s Court of Guangxi Zhuang Autonomous Region are clear, the evidence is true and sufficient, the conviction is accurate, and the sentence is appropriate. The trial procedure is legal.

  Therefore, it was approved that the Higher People’s Court of Guangxi Zhuang Autonomous Region agreed to the criminal ruling that the defendant Tan Taijian was sentenced to death for robbery, deprived of political rights for life, and confiscated all personal property.

  Before the execution of the death penalty, the Intermediate People’s Court of Hechi City arranged for the criminal Tan Taijian to meet with his close relatives according to law, which fully guaranteed the legal rights of the executed criminal.

Kunming’s take-away orders rank third in southwest China! What office workers love most is …

Zhang Shang chun cheng XunAt present, with the resumption of work in various places, the consumption of food and beverage takeout that was suppressed during the epidemic period is gradually released. On March 11th, the reporter learned from Meituan Takeaway that the first Consumption Report on Restaurants’ Takeaway during the epidemic period (hereinafter referred to as "Report") was released. Since the resumption of work, the number of take-away merchants, order volume, transaction volume and other indicators have shown a steady rise, and 30% of the merchants’ take-away orders exceeded those before the epidemic. Two weeks before the resumption of work, the number of take-away orders in Kunming ranked 12th among major cities in China and 3rd among major cities in Southwest China, showing a relatively strong consumption power.
The surge in take-away orders has boosted the catering economy.
According to the incomplete statistics of the US Mission, the return to work rate of catering merchants in China has exceeded 55%. According to the Report, since the resumption of work for two weeks (February 17-March 1), the two main data of food and beverage take-away transaction volume and order volume in major cities in China have shown a sharp growth trend. The data show that the consumer demand that was obviously suppressed during the epidemic period was further released on the take-away platform, and the take-away economy took the lead in recovery.
In particular, orders in first-tier cities have grown rapidly, and the Top5 orders in China are Shenzhen, Guangzhou, Beijing, Shanghai and Chengdu respectively. Two weeks before the resumption of work, among the major cities in China, Kunming ranked 12th in order quantity, and among the major cities in southwest China, Kunming ranked third after Chengdu and Chongqing, showing a relatively strong consumption capacity.
According to the "Report", 30% of the merchants in the country have more take-away orders than before the epidemic. At present, due to the prevention and control of business closures, catering businesses in various places have not recovered their vitality, and the take-away business has provoked the catering economy. Merchants have increased their volume and income through the take-away platform to combat the impact of the epidemic.
It is worth mentioning that the Report shows that the take-away orders and revenues of catering businesses in major cities have developed rapidly. Among them, the growth of second-and third-tier cities is particularly obvious. Among the national businesses, the proportion of businesses with a single volume exceeding that before the epidemic is Urumqi, Harbin, Nanchang, Xi ‘an and Dongguan. 38% of the merchants in Kunming have better take-away orders after returning to work than before the epidemic, ranking 11th in the country and 1st in the southwest, ahead of Chongqing and Chengdu.
After 60 s and 70 s, users joined the takeaway consumption army.
According to the Report, the growth rate of new users in major cities across the country has exceeded 50% for two consecutive weeks. Takeaway has become the most important living security and urban infrastructure since returning to work.
According to the survey, although the post-90s generation is still the main group of take-away consumption, among the new users, the post-60s and post-70s consumer groups, who originally preferred to cook at home, have sprung up, buying fresh vegetables for their families, buying beer for themselves, and ordering themselves a piece of braised chicken rice after returning to work. The post-60s and post-70s accounted for 36.7% and 31.5% respectively, which became the main force for the growth of new take-away customers and successfully joined the "take-away sweeping group".
The top three business districts with the fastest growth rate of orders in major cities are shopping malls, office buildings and software parks. The commercial buildings in cities are gradually bustling and are accelerating their recovery. The fastest growing business districts among the Top5 cities in China are: Beijing-Wangjing, Shanghai-Lujiazui, Guangzhou-Zhujiang New Town, Shenzhen-Futian CBD and Chengdu-Financial City.
At the same time, multi-person meals are becoming a popular take-away mode, and the number of multi-person orders with more than three people has increased by more than 150% from the previous week. Urban white-collar workers from all corners of the country have different tastes. In the past, even an office and a take-away work meal could make up the "eight major cuisines". But now, in order to reduce the contact links such as taking the elevator, it has become a new trend for colleagues to book the same restaurant together and take turns to take takeout.
More people buy vegetables with takeout. Hot pot is popular after returning to work.
According to the Report, the proportion of non-food orders increased by over 77% during the epidemic. Everyone has encountered "quasi-isolation", so it is a new day to take protective measures, buy ingredients at home and study cooking. During the Spring Festival, the average sales volume of food products including vegetables, meat and seafood on Meituan’s take-out platform increased by 200% month-on-month. Among them, 3.93 million copies of onion, ginger and garlic were sold, nearly one million copies of coriander were sold, and people bought more than 5 million masks. In Xi ‘an, which loves pasta, dry yeast won the regional sales volume of Top5, while in Shenyang, a city in the north, the take-out sales volume of Top1 was actually hot pot dipping.
More users purchase daily necessities such as fresh fruits and vegetables, daily necessities and medicines through the take-away platform. After returning to work, non-food categories continue to maintain a steady growth rate, and the epidemic has gradually formed new lifestyles and consumption habits.
However, with the resumption of production, cooked food has been greatly welcomed. In Kunming, hot pot, Southeast Asian food, spicy pot, barbecue and western food are the most popular Top5 for office workers. Among them, the order volume of hot pot take-out increased significantly, and the second week of resumption of work increased by more than 50% compared with the first week.
The cities with the highest sales volume of hot pot takeout in China are Chengdu, Beijing, Shanghai, Hangzhou, Guangzhou, Nanjing, Chongqing, Suzhou, Shenyang and Dongguan.
In addition to hot pot, the most popular dishes in various places have more local characteristics, such as the barbecue of mutton tendon in Beijing, the rice congee for clearing fire in Shanghai, rice rolls in Guangzhou, assorted maocai in Chengdu and Hu spicy soup in Xi ‘an. After returning to work, people prefer hot local dishes.
Under the influence of COVID-19 epidemic, the safety of take-away food has become the biggest focus of public attention. According to the "Report", more than 80% of take-away orders have chosen to use the "no-contact and safe delivery" service, and the demand for intelligent meal-taking facilities has greatly increased.

The "Youth League Year" is on fire. What is it? People outside this province are shocked!

Coordinate Jiujiang, Jiangxi Province, there is a League Year, which is a ceremony for the whole village, old and young, to worship their ancestors collectively in the ancestral temple. Strictly speaking, it should be the moment when the ugly time meets at midnight on the 30 th, and the year ends and the new year opens. Last year ended, so it is also called "the end of the year". However, the word "finished" is taboo in customs (meaning finished), and Tujili is more called "the year of reunion" (a year of complete reunion). In the development of time, slowly, some still insist on holding this ceremony in the middle of the night, some change it to the evening, and some change it to the early morning (it has reached the first day). My village is more interesting. This ceremony is held in the morning of the 30th instead of the evening.
