The relevant matters concerning the nationwide full implementation of the National Sixth Emission Standard 6b for light vehicles and the National Sixth Emission Standard 6b for heavy diesel vehicles (hereinafter referred to as the National Sixth Emission Standard 6b) are announced as follows:

1. From July 1, 2023, the national sixth emission standard 6b stage will be fully implemented, and the production, import and sale of automobiles that do not meet the national sixth emission standard 6b stage will be prohibited. The production date is based on the vehicle manufacturing date of the motor vehicle certificate, and the electronic information of the certificate should be uploaded before 0: 00 on July 1, 2023; The date of import is based on the date of arrival of the goods import certificate; The date of sale shall be subject to the date of motor vehicle sales invoice.

Two, for some of the actual driving pollutant emission tests (that is, RDE test) report results as "monitoring only" and other light vehicles, give a half-year sales transition period, allowing sales until December 31, 2023.

Three, automobile production and import enterprises, as the main body responsible for the consistency management of environmental protection production, should disclose the vehicle emission inspection information and pollution control technical information before the vehicle leaves the factory or enters the country according to the relevant provisions of the People’s Republic of China (PRC) Air Pollution Prevention Law, so as to ensure that the actually produced and imported vehicles meet the requirements. Relevant certification bodies shall issue compulsory product certification certificates according to the national six emission standards 6b stage.

　　Recently, a master’s thesis entitled "Sociological Research on Fart" was circulated on the Internet, causing controversy. Some netizens are "sarcastic": Cold Window has studied hard for so many years, and it is really a "fart". Some netizens commented after reading that things that seem meaningless and are sneered at are "serious things to dig into."

　　The Paper noted that the paper was written in 2007 by Gao Jianwei, an in-service master of sociology at Huazhong Normal University. At that time, Gao Jianwei not only passed the master’s thesis defense with this paper, but also was rated as "excellent".

　　As early as 2015, the paper had aroused public concern. Li Yaxiong, a tutor of Gao Jianwei and a professor at Huazhong Normal University, said in an interview with the media at that time, "There are actually many aspects in life that are worth exploring, and there is no need to always repeat some meaningless topics. Some topics that look different or niche are often more worthy of consideration and there will be more interesting discoveries."

　　In this regard, Zheng Zuoyu, a professor at the School of Sociology of Huazhong University of Science and Technology, believes that whether the paper can be written well depends on whether the attitude is correct. In his view, even if the topic is high, but the attitude is not good, "no use"; On the contrary, if the academic attitude is correct, the topic "No matter how bizarre it is" can also be described as a classic.

　　The thesis was praised by the tutor.

　　"I am often mentioned by people around me such a question: How did you do such a topic?" Gao Jianwei explained at the beginning of his thesis "Sociological Research on Fart" that he chose this topic because he accidentally saw two stories about fart on the Internet. In both stories, the protagonist changed his life track because of a fart, which triggered Gao Jianwei’s thinking.

　　Gao Jianwei believes that "fart" is not only a physiological phenomenon, but also a social phenomenon, which has various correspondences with social relations. Through the study of a large number of historical materials, he pointed out that fart exists as a social taboo in both western culture and eastern culture. This taboo not only spreads in all aspects of our daily life, but also widely exists in the superstructure fields such as education, manners and customs, habits, morality and even law.

　　Gao Jianwei deeply analyzed how fart behavior and phenomenon changed from a physiological behavior to a social taboo from the perspective of social genetics, and revealed the complex mechanism of this operation process. In the process of social development, fart has evolved from indiscriminate human behavior to behavior that occurs more frequently among some social members, and then to negative behavior in moral evaluation, and finally evolved into a form of social taboo.

　　The paper mentions that in the early stage of human beings, division of labor and class have not yet appeared, and fart behavior is primitive human beings — — That is, the most frequent and common physiological phenomenon of our ancestors. With the development of productive forces, social relations have changed, and the diet types and habits of the rich have changed, and they no longer fart frequently. At this point, the human fart experience has completed the first historic change, that is, from a common physiological phenomenon of human beings to a behavior that occurs more frequently and more commonly among some members of society (more poor people).

　　Through this transformation, fart behavior has gained some social significance, reflecting the fact that the upper and lower classes coexist and oppose each other. In order to maintain its dominant position, the upper class not only establishes an absolute control position in the political, economic and cultural fields, but also strives to "shape" the social state that adapts to its dominant position. Distinguish the upper and lower classes by etiquette, self-cultivation and taste. The upper class is often considered polite, while the members of the lower class are ordinary, vulgar and even despicable. In this context, farting is labeled as a negative moral label. Under the power of discipline, "fart" has changed from a negative social behavior defined by the upper class to a social taboo, and has been recognized and obeyed by all members of society.

　　He believes that this genetic process comes from the strange characteristics of power operation, namely, duality, dependence and publicity. Then it discusses the fart behavior and phenomenon of "no taboo", and thinks that this phenomenon essentially reflects the taboo existing form of fart behavior and phenomenon, and is related to the strange characteristics of power operation.

　　The Paper noted that this is not the first time that this paper has been concerned by netizens. In 2015, Beijing Evening News reported on this matter. Li Yaxiong, Gao Jianwei’s tutor and professor of Huazhong Normal University, was quite appreciative of the paper when interviewed.

　　According to his memory, when the paper was opened, the teachers all laughed at the first sight of the topic, but after the "laugh", everyone quickly discussed its academic value from a professional point of view, not simply talking about the matter, but using sociological theory for analysis. Li Yaxiong told the Beijing Evening News reporter at that time that Gao Jianwei’s research found a new way. In the case of repeated research, it was "precious" and teachers generally supported it.

　　"The defense effect is also very good, and it has also been rated as excellent. He (Gao Jianwei) has a good writing style and clear thinking. " Li Yaxiong said that because it is not convenient to do actual investigation, Gao Jianwei presented the genesis of fart, its vertical development in different times and the social meaning behind it through literature analysis and quotations. "I welcome this topic that comes from life and has humanistic care."

　　In this regard, The Paper recently contacted Professor Li Yaxiong several times for an interview, but the other party declined on the grounds of being away on business.

　　College teachers: With a correct attitude, no matter how strange the topic is, it can become a classic.

　　In fact, in recent years, many papers have attracted public attention because of their unique topics. Previously, papers such as "The Utopian Cat: The Identity and Fantasy of Cats Fans" and "The Influence of Illicium verum on the Volatile Flavor of Braised Chicken and Its Mechanism" have caused heated discussions.

　　"This is a question of diversification of topics, which I think is a good thing." Rui Liu, tutor of master students in Huazhong University of Science and Technology, believes that the development of disciplines is characterized by "specialization" and "cross-integration", and "many problems that we didn’t think could be studied before have emerged now". "Personally, I think it is necessary to study such different problems, which can cover many blind spots of previous knowledge and inspire the society." Rui Liu said in an interview with The Paper recently.

　　In this regard, Zhou Tingting, an associate professor at the School of Journalism, Huazhong University of Science and Technology, believes that college students are active in thinking or familiar with new media, so they can really pay attention to some new phenomena. "Many phenomena can be used as the research topics of our thesis, but we should find an in-depth observation angle based on the discipline, not just describe ‘ Phenomenon ’ It is meaningless to do a simple analysis. " Zhou Tingting said.

　　Tan Songhua, a member of the National Education Advisory Committee, said that he had not read the above papers and could not comment on them. "How to write a graduation thesis, it is difficult to have a unified statement. Students with different majors, hobbies and energies have different factors to consider when choosing a topic. " Tan Songhua said that as far as he guides graduate students, the practical significance is more important when choosing the topic of the thesis, for example, it can promote the development, reform and social progress of the country.

　　For more and more "unique topics", Zheng Zuoyu, a professor at the School of Sociology of Huazhong University of Science and Technology, said that "there is nothing wrong with it". "Academic research should have cared about your life and the society you live in. Now that the era in which students live is full of these phenomena, it is natural to study these phenomena. " According to Zheng Zuoyu, the question is not whether the research topic is "innovative" or "serious", but whether the research attitude is correct.

　　Zheng Zuoyu said that individual students "lead a muddled life" and "choose the most mindless topic" when writing their papers. "Such a topic, even if it sounds tall, is actually vague." Zheng Zuoyu said that attitude is more important for writing papers.

　　"When I take part in the insurance research interview, I will ask students what fields they are interested in and have studied." Zheng Zuoyu found that most students from rural areas would say "I want to do rural research", or most female students would say "I want to do gender research". "But not many of these students have really studied the relevant knowledge. They just think that because of their identity, they can make some sense at worst. " Zheng Zuoyu believes that in this case, even if the topic is tall, the attitude is not correct, and it is "no use"; On the contrary, if the academic attitude is correct, the topic "No matter how bizarre it is" can also be described as a classic.

　　What do students think about the topic of the thesis? Li Yong (pseudonym), a graduate student in a university in Hunan, told The Paper that according to his observation, the source of the topic mainly has three parts, one is the combination of previous practical activities, the other is the combination of interests, and the third is from the tutor. "I prefer topics that I am interested in, and at the same time consider the significance of research, so I am motivated to write." Li Yong believes that interest is a good entry point. "When the school informs you to write a paper, you often feel confused and then choose a familiar field." (The Paper reporter He Liquan intern Hu Tianyi)

　 　

　 　Special feature of 1905 film network　The summer file in July, also known as domestic protection month, saw eight domestic films released on July 8 alone. Among them, there is a literary film "Winter" with little publicity before, which will "go to war" on the same day as "Chill 2", "Rock Tibetan Mastiff", "Big Fish Begonia" and "never gone", and the box office prospect is really not optimistic.

The film released on July 8 　 　

　 　Looking at the literary films in the summer file, Winter is not fighting alone. The Roadside Picnic, which will be released on July 15th, will also face fierce challenges from other major rivals, such as The Great Reversal starring Xiao Wa, day trader the Quick Shooter starring Zhang Jingchu and Kenny Lin CP, and the article director Virgo Lu Yao Zhi Ma Li.

The film released on July 15th. 　 　

　 　 It seems to be a right thing for literary films to hide in the domestic protection month, but it can only be said that the risk is small in the schedule. How does the literary film break through the schedule dilemma and get higher film arrangement and box office? Is it difficult for every literary film to kneel like Fang Li? In the final analysis, this should be combined with the promotion of literary films themselves and the development status of mainland art theaters.

　 　 In the Mainland, there was a real representative of the cinema, who explained the discovery of literary films and the development dilemma of art cinemas. She was the program and promotion manager of Beijing Broadway Film Center — — Yang Yang.

　 　　Program and Promotion Manager of Beijing Broadway Film Center — Yang Yang

　 　 The survival status of art cinemas is inseparable from the prosperity of the literary film market, so Yang Yang’s viewpoint is also representative, which is difficult to copy, because there is only one art cinema in the mainland. "The Broadway Film Center has done statistics. The ratio of literary films to commercial films is 1: 10, but the attendance rate is only 1:3. It can be said that all the money is earned from commercial films." From these words, it is not difficult to see that it is almost impossible for a cinema to maintain its operation only by literary films, even if it is an art cinema.

Beijing Broadway Film Center

　 　 Then the question came, and people began to think whether literary films should be shown in art theaters for a long time. But from Yang Yang’s words, we can see that after the establishment of the Art Cinema, there seems to be no improvement in the "way out for literary films". What’s the problem? Is it that the publicity of literary films is not in place, or is it unreasonable to arrange films in cinemas? Why do we see so few literary films when there are art cinemas in the Mainland?

　 　 With these questions, Zi Shijun specially went to Beijing Broadway Film Center and had a good chat with Yang Yang about the announcement of domestic literary films and the operation of art cinemas.

[See the manager of the art theater talking about the myth of domestic literary films]

　 　 Broadway Film Center, established in December 2009, is a Hong Kong-owned art cinema, located in a residential area of Xiangheyuan Road in Dongzhimen, operated and managed by Hong Kong Anle Film Co., Ltd. Before the opening of this one in the Mainland, Anle had successfully operated an art cinema in Hong Kong called Hong Kong Broadway Film Center. With the experience of successful operation, the founding concept of Broadway Film Center in the Mainland also wants to be consistent with it, to provide screening for high-quality literary films at home and abroad, and to expand the exchange of film culture.

　 　 Yang Yang’s job is to select excellent films from the domestic literary films every year, and implement the corresponding film arrangement and post-screening exchange activities. During this period, she also saw the problems faced by mainland literary films, large and small. She told us that "several small partners in her team can even be regarded as a small company for the publication of mainland literary films for a long time".

Earlier, we were equivalent to a literary film publishing company.

　 　 In the early years, some domestic literary films with relatively small volume did not try to be released nationwide at all, such as Cao Baoping’s Glorious Wrath. Before its release, Beijing Broadway Film Center was almost equivalent to their publicity company, which did everything from posters to brochures, as well as writing all press releases and inviting media.

The implementation of Yang Yang’s various ideas was completed on this desk.

　 　 Q: Does this mean that for these small-scale literary films in the early days, do you still announce them here?

　 　 A: In the early days, this movie was very small. I think there was a big difference in the past two years from "Fireworks by Day", but "Fireworks by Day" is a special case that can’t be copied. Since then, plus the rapid growth of the whole China movie market, everyone wants to go to the national release, hoping to replicate a miracle in it.

You cann’t just lay out the whole line at every turn.

　 　 Q: You said earlier that the team was unprofessional, such as selling dog meat by hanging sheep’s head?

　 　 A: Isn’t that what commercial movies are all about? Just find a selling point, whatever it is, just drag it there first.

　 　 Q: What do you think are the unprofessional behaviors of domestic literary films in propaganda?

　 　 A: The announcement of an art film is a difficult thing to do all over the world. Its idea is not for profit, and it is not made for the maximum benefit. So when you announce it, you have to be patient and take a long line. Is there anything better that can bring out its commercial benefits? Like now, there is no particularly good model. I have also asked Anle’s colleagues in Hong Kong, who also bought some small non-Hollywood films in Hong Kong very early, but I feel that they don’t have a particularly good model, including Taiwan Province, but they are all very small. If you follow that, the distribution of these films in China is not particularly bad.

　 　 Q: Do you think that these domestic ideas of putting on a full-screen screening are actually wrong?

　 　 A: I think this idea may need to be changed, because before, only the film center was on the long line, and this volume was a little too small. I understand that they are not satisfied with only showing it in one theater, and I also think it needs to be expanded, but it is unrealistic for you to really compare it with commercial films, even with Fireworks in the Day.

　 　 Q: Before "Fireworks in the Day", there was a saying, why not learn from the United States, first show it on a small scale, and then expand it? Do you think it is difficult to realize this?

　 　 A: To a certain extent, the current publicity companies can’t settle down to do this. If it’s small, you have to choose a cinema and talk about it one by one. Now there are so many publicity weeks for a film, and there are so many cycles for a film. After this project is over, he will immediately enter the next project, no matter what happens to the film in the later stage, but these films must be fermented by word of mouth for a long time before they can be done slowly.

Many literary films will be wasted if they do this.　

　 　 But generally speaking, it is hard to achieve any box office miracle, that is, you accumulate slowly, but now no one is doing this, and there are not even a number of cinemas, even if only 20 or 30 people want to do this, and now it is Broadway, with at most an intermediate cinema. I don’t know what other cinema companies are like, but there are a few cities in Broadway that are suitable for our own company, and then the managers are willing to cooperate. They also know what to do, but they still can’t become a mass.

　 　 In fact, many domestic literary films may not be publicized, and many cinemas simply don’t arrange them. Zi Shijun interviewed some cinema managers when "A Hundred Birds at the Phoenix" was released. Their first reaction was, I haven’t seen it, I don’t know about it.

There is a horse on the other side of the mountain, with a domestic box office of 240,000.

　 　 For example, there is a horse on the other side of the mountain released in May, and the number of films is even lower. The Broadway Film Center has never seen the film, because Yang Yang is familiar with Huang Lu, and she took the initiative to find the producer through her, and then told them whether to come and have a post-screening exchange. "But they haven’t done some movie-watching activities before, and the director happened to be going to other places, and then Huang Lu couldn’t come because he had to shoot, feeling that they gave up on propaganda, and many films would be wasted."

Xinhua News Agency, Beijing, July 14th Question: how to ensure supply and price stability if it continues to operate at a low level? -Price articles of mid-year economic research bank

Xinhua news agency reporter

Prices are related to economic operation and affect people’s lives. In the first half of this year, China’s prices maintained a stable operation, but since the second quarter, due to multiple factors, the increase has declined.

In the first half of the year, the national consumer price index (CPI) rose by 0.7% year-on-year, lower than the 1.7% increase in the same period last year. Among them, in June, CPI rose by 0.2% year-on-year from last month to flat, down by 0.2% month-on-month.

How to treat the current price trend? In the past few days, Xinhua News Agency reporters have conducted in-depth investigations in Hunan, Jiangsu and other places, and have truly felt that all parties have a solid support for effectively coping with price fluctuations, continuously strengthening the supply and stability of prices, and maintaining the stable operation of prices throughout the year.

Guarantee the supply of important commodities for people’s livelihood

Near the evening, many citizens are choosing pork, eggplant and other products at Chanan Farmers’ Market in jianye district, Nanjing, Jiangsu.

"Now, the price of vegetables and meat is generally low. The price of ordinary pork belly has dropped to more than 10 yuan a catty, and the’ vegetable basket’ is more comfortable." Aunt Xu, a Nanjing citizen who came to the market to buy food, said.

Since the beginning of this year, prices have continued to fall due to the time difference between supply and demand recovery and the high base.

Lower prices will help to reduce the cost of living of the people, but for the relevant production enterprises, it means that the sales price will fall, resulting in shrinking profits.

In the fruit trading area of Red Star Global Agricultural Products Wholesale Center in Changsha, Hunan Province, watching boxes of durian imported from Vietnam being unloaded in an orderly manner on the cold chain transport vehicle, Zhang Xinghua, the head of the "Fruit Taoren" business department of Hunan Fruit Friends Company, recorded the weight of durian in detail in a notebook, and roughly calculated the cost and estimated income.

"At the beginning of this year, we added a Vietnamese durian procurement contract. Durian shipments increased by 20% compared with last year, but the market sales volume was delayed, the average sales price fell, and the income continued to decline." Zhang Xinghua said.

Restricted by unstable income expectations and other factors, the demand of high-end fruit market has declined as a whole, which is a challenge for fruit wholesalers.

How to meet the challenge? Zhang Xinghua mainly plays "two cards".

"On the cost side, improve procurement efficiency, further optimize import transportation routes and reduce expenses; On the sales side, strengthen the national market pre-judgment and adjust shipments in a timely manner. For example, the price of durian in some cities in the north has rebounded, which will increase the supply to these cities. " Zhang Xinghua said that the company’s durian supply is still sufficient.

From the perspective of food prices, the fluctuation of pork prices is more obvious. In June, the price of pork decreased by 7.2% year-on-year, which was 4 percentage points higher than that of the previous month.

According to industry insiders, the pig breeding industry has been losing money for many months, and some pig enterprises have even fallen into the dilemma of "selling more and losing more". Under the pressure of low pig prices, most pig enterprises practice "internal strength" hard to improve management efficiency and fully hedge the risk of lower pig prices.

The reporter walked into the pig breeding factory of Mu Yuan Agriculture and Animal Husbandry Co., Ltd. in Lishui, Nanjing. Locating bars, intelligent environmental control, precision feeding and other equipment were widely used in pig houses. The pregnant houses and delivery rooms were clean and tidy, and almost no pungent odor was smelled.

"By using digital technologies such as automatic inspection and intelligent recipe feeding, the daily gain of pig fattening exceeded 1000 grams, the survival rate increased by about 5%, and the breeding efficiency was greatly improved, which greatly alleviated the impact of this round of pig price decline." Qin Shaojun, regional manager of Sunan of Mu Yuan Group, said that the supply of live pigs in the group is generally stable at present.

Guaranteed supply and stable price, all localities are working hard. Jiangsu identified 881 emergency supply enterprises for daily necessities, established a special supply network and increased supply outlets; Jingde County, Anhui Province guides key commercial enterprises to broaden sources of supply and strengthen supply reserves; Xi ‘an, Shaanxi Province opened the "Bus Vegetable Basket Huimin Station" to deliver fresh agricultural and sideline products to residents’ doorsteps through "direct mining, direct supply and direct sales" …

"In the face of multiple pressures, all localities and departments made efforts from both sides of supply and demand, strengthened the analysis and judgment of price trends, and timely adopted targeted price stabilization measures. In the first half of the year, the supply of important people’s livelihood commodities was sufficient, and the CPI generally maintained a moderate increase." Wang Likun, an associate researcher at the Institute of Market Economy of the State Council Development Research Center, said.

Actively respond to the downward impact of PPI

Coordinate the delivery schedule with the steel sales company, communicate with the old customers about the demand for steel, and adjust the delivery schedule by staring at the online steel price trend in real time … Yanyu, who has been engaged in steel agency for 15 years, said frankly that "steel prices have been bottoming out and I feel very nervous".

"This year, we signed a purchase agreement with Handan Iron and Steel Co., Ltd. for more than 60,000 tons of construction steel and cold-rolled steel plates, and shipped more than 5,000 tons of steel every month as planned, but since the beginning of the year, the price of steel has continued to be sluggish, with a year-on-year decline of about 30%." Smoke jade said.

"Low price" is the feeling of many commodity enterprises this year.

Mainly affected by international import factors, commodity prices continued to fall. In the first half of the year, the national producer price index (PPI) decreased by 3.1% year-on-year, and the decline expanded month after month.

In the investigation, the reporter found that relevant industries are actively responding to the downward impact of PPI through innovative measures such as adjusting product structure and improving industrial chain.

At 4: 00 pm on June 28th, the oil tanker "Haixinyou 616" was loaded with 9981 tons of aviation kerosene and sailed from Pier 11 of Jinling Petrochemical Company of China Petrochemical Company to Shanghai Pudong Airport, which was the sixth oil tanker that the company sailed that day.

Facing the downward fluctuation of international crude oil price and the shrinking profit space of refined oil, chemical products and by-products, Jinling Petrochemical Company of China Petrochemical Company aimed at market demand, increased the production and supply of aviation kerosene, high-end graphite materials, aromatic hydrocarbons and other products, and tapped new profit growth points.

"In the first half of the year, the output of aviation kerosene increased by 35% year-on-year, which not only helped to ensure the recovery of the civil aviation industry, but also increased revenue and efficiency for enterprises." Liu Wenbao, manager of the production planning department of Jinling Petrochemical Company of China Petrochemical Company, said that we expect that there is still room for growth in sales and profits throughout the year.

PPI is related to the price of raw materials, and its decline is expanding, which increases the operating pressure of upstream enterprises, but it is conducive to reducing the production costs of downstream industries such as home appliances and paper making, which is good for downstream enterprises.

"Affected by positive factors such as falling raw material prices and stable sales, the consumption of household appliances such as air conditioners and refrigerators maintained a relatively high growth in the first half of the year, and the unit price growth rate of user consumption was above double digits. On average, there were more than 50 stores in various formats such as Suning Yijia Plaza Store and Suning Yijia Flagship Store." The person in charge of Suning.cn said.

Li Gang, a researcher at the Institute of Industrial Economics of China Academy of Social Sciences, analyzed that PPI is mainly affected by changes in the international market, and it is not completely synchronized with CPI fluctuations. Keeping its fluctuation range at a relatively reasonable level is conducive to the coordinated development of upstream and downstream industries. Recently, the policy of stabilizing industry has been continuously introduced, some of which are taking effect, helping enterprises to stabilize orders and expand the market, and the cardinal utility has weakened. The year-on-year decline of PPI is expected to narrow in the second half of the year.

Prices may remain moderately rising.

As an important indicator of macroeconomic operation, the price increase has continued to fall, even causing some concerns about the economy falling into deflation. Will prices continue to fall in the second half of the year? How to treat the price situation? The reporter came to the front line to observe the price dynamics.

Xinfadi market is called the "vegetable basket" of Beijing citizens. Tong Wei, the person in charge of Xinfadi Market, said that recently, the average daily market volume of vegetables has stabilized at around 19,000 tons, and the prices of some vegetables have increased due to the rebound in demand. For example, cucumbers produced in Langfang, Hebei Province have high tenderness and good taste, and the demand continues to increase, driving up prices.

According to the data of key e-commerce platforms, the demand for fruit consumption in the season is strong, and the price of fresh fruit is expected to pick up. "Recently, we have increased the purchase of seasonal fruits such as peaches and bayberries, and launched hundreds of products to cool off the summer and ensure market supply." The person in charge of the US group buying food said.

At present, the price of "vegetable basket" has increased year-on-year. According to the monitoring of the Ministry of Agriculture and Rural Affairs, from July 3 to July 9, the average weekly wholesale price of 28 kinds of vegetables monitored mainly increased by 13% year-on-year.

The price trend is the same as that of the "vegetable basket". Under the influence of policies such as promoting consumption, the prices of home appliances and tourism are on the rise.

At present, Suning.cn has further increased the supply of high-end household appliances. "Recently, the order volume of high-end home appliances has continued to increase, and it is expected that the unit price of user consumption will further increase." The person in charge of Suning.cn said.

According to Wang Likun’s analysis, with the increasing endogenous kinetic energy of China’s economy, the bilateral recovery of supply and demand tends to be balanced, and the market circulation order continues to improve, market confidence increases and expectations continue to improve. It is expected that the overall price increase will gradually return to a reasonable level in the second half of the year.

The National Energy Administration urged power generation enterprises to implement a stable supply of coal and gas, sign a medium-and long-term contract agreement on coal and gas with good quality and quantity, and actively respond to the peak of electricity consumption this summer; The National Development and Reform Commission will, together with relevant parties, start the second batch of central pork storage and purchasing during the year, and guide all localities to synchronize storage and purchasing, so as to push the price of live pigs back to a reasonable range as soon as possible; Hubei and Beijing issue a new round of coupons …

Recently, all parties have made active efforts from both sides of supply and demand to ensure the supply of important commodities for people’s livelihood and promote the continuous recovery of consumer demand. According to industry analysts, at present, China’s total economic supply and demand are basically balanced, and the monetary conditions are reasonable and moderate. At the end of June, the broad money (M2) balance increased by 11.3% year-on-year; Residents’ expectations are stable and there is no basis for long-term deflation or inflation.

"From the perspective of the whole year, with the steady expansion of China’s market demand and the gradual increase of production and supply, the relationship between supply and demand is expected to be generally stable, and consumer prices will generally maintain a moderate increase." Fu Linghui, spokesman of the National Bureau of Statistics, said. (Reporter Wei Yukun, Gao Kang, Yan Fujing, Zhao Jiulong, Zhou Nan)

Have not had sex all the time, can you not do gynecological examination?

First of all, answer the first question: even if you have never had sex, you need to have a gynecological examination.

Of course, here we should distinguish between broad and narrow gynecological examinations. When it comes to gynecological examination, many fairies first associate it with gynecological examination.

It requires women to lie on a special gynecological examination bed, and doctors can open the yin channel through a speculum (duck-billed forceps) to check the yin channel and the cervix, and if necessary, take samples and check the secretion of the yin channel and the exfoliated cells of the cervix, and then know whether there is any abnormality in the uterus and bilateral ovarian fallopian tubes through Shuang Hezhen or triple diagnosis.

The gynecological examination that our doctors usually say includes a series of laboratory tests such as ultrasound and tumor markers, in addition to physical examination.

For female friends who have never had sex, gynecological examination is definitely not suitable, but this does not mean that we don’t need gynecological examination.

We should not actively ignore or passively refuse gynecological examination because we have never had sex.

Yaota met many female patients who had never had sexual life in clinical work. It was precisely because of the wrong idea that there would be no gynecological diseases without sexual life that the best treatment opportunity for the disease was delayed. Among them, there were many cases of malignant tumors, which can be said to be a lesson of blood.

What makes me feel most sorry is a patient not long ago. She never had sex, so she never had a gynecological examination. She had a gynecological B-ultrasound by chance and found a tumor in her uterus. She sought some Chinese medicine treatment by mistake, but it didn’t work. One day she came to our hospital because of acute abdominal pain.

We thought it was just a simple fibroid degeneration, but after the operation, we realized that the condition was far more serious than we thought. The final postoperative pathology was uterine sarcoma, a highly malignant uterine tumor.

After surviving the postoperative rehabilitation period and unusually uncomfortable chemotherapy, I thought everything was going well. However, less than a month after the end of chemotherapy, the tumor recurred and metastasized to the intestine, and she underwent laparotomy again.

The last time I contacted her, she told me, Yaota, I won’t go to your hospital. The tumor has metastasized to the lungs. I’ll go to another hospital. Later, I didn’t see her update her circle of friends. I don’t know how she is now, but I can still remember her strong smile.

Forgive the demon tower. I’m old, and I feel it. It’s a bit far.

What tests should I do if I have no sex life?

Then answer the second question: even if we have never had sex, we can still do gynecological B-ultrasound (transabdominal or anal ultrasound); You can also check yin secretion, tumor markers and hormone levels. And from the point of view of gynecological physical examination, although we can’t do Shuang Hezhen, we can learn about pelvic cavity through anal examination when necessary.

Gynecological B-ultrasound: It can help us to know the thickness of endometrium, whether there is abnormal echo in uterine cavity (such as endometrial polyp and submucosal myoma), whether there is abnormal echo in myometrium (such as hysteromyoma and adenomyosis) and whether there is abnormal echo in ovarian fallopian tube (such as ovarian tumor and hydrosalpinx);

Yin secretion: it is not that there will be no yin inflammation without sexual life! Doctors can use a cotton swab to get yin secretion for laboratory examination without opening the yin channel with a speculum.

Tumor marker: This test is more routine and simple, that is, blood drawing. Among many tumor markers, CA125, which is closely related to female diseases, is the most common and you know the most. Generally speaking, CA125 will be elevated in many cases, such as before and after menstruation, endometriosis, adenomyosis, pelvic inflammatory disease and ovarian malignant tumor.

Hormone level: including six items of sex hormones, AMH and other tests, we often need to use the results of six items of sex hormones to help doctors judge the condition when diagnosing and treating female endocrine diseases such as abnormal uterine bleeding and polycystic ovary. AMH can help us understand the reserve function of female ovaries and better guide pregnancy preparation. These are also blood tests.

What will happen if I accidentally do the yin examination?

The third question: What will happen if you accidentally do the yin examination?

Before answering this question, first of all, we need to be clear. First, we can’t choose not to check out because of fear or concern. Second, when we ask the doctor, we should clearly tell the doctor that I have never had sex before, so as to avoid the possibility of accidentally doing yin examination to a great extent.

Through the description of gynecological physical examination in Yaota, I believe you may have guessed that the following may happen to women who have no sexual life after yin examination.

ache

Yin Dao flap (common name hymen) is a mucous membrane with certain elasticity. With the invasion of speculum, yin Dao flap has not broken yet, but it will induce vulvar pain due to expansion. At this time, something must be done to stop it.

Rupture and bleeding of yin valve

Some female friends have high elasticity of the yin valve, and there may be no obvious pain in the process of entering the speculum, but with the opening of the upper and lower leaves of the speculum, the yin valve will basically rupture or even bleed during this process.

At this time, it is necessary to compress the wound to stop bleeding. Generally, a sterile cotton ball will be selected, and it will be removed after 5 to 10 minutes of compression to observe the bleeding of the wound.

Because the yin flap is thin, there are often some capillaries distributed here, which can basically stop bleeding through compression. However, if it happens to damage a relatively large blood vessel, it may be necessary to stop bleeding through suture if necessary, but this situation is very rare.

infect

If this happens unfortunately, you must pay attention to the cleanliness of the vulva after the bleeding stops, so as to avoid infection of the wound. Of course, this kind of situation is also very rare, because this kind of wound of yin mucosa usually heals very quickly.

Yao ta Xiao tips

If the doctor gives you a gynecological B-ultrasound checklist, you must see clearly whether it is through the yin channel, abdomen or anus before paying the fee. If it is through the yin channel, or if you feel that you can’t accept the transanal B-ultrasound examination, you must find a doctor to change the checklist.

Original title: "It is strongly recommended that all women must do these four tests during physical examination (whether they have sex or not)"

　　Some professional qualification certificates can be inquired through the national networking system.

　　Investigation on the phenomenon of illegal sale of "real certificate"

　　Investigation motive

　　It seems that the demand for various qualification certificates through informal channels has not decreased, which can be seen from a fraudulent case of manufacturing and selling fake certificates on the websites of state organs uncovered by the police in Nantong City, Jiangsu Province. In this case, the police have initially identified more than 34,000 pieces of information about people who handle false certificates, involving labor and personnel, science, education and culture, health care and medicine, engineering construction and other fields, and the personnel are distributed in more than 20 provinces, cities and regions across the country.

　　Where there is demand, there is market. From street poles to online shops, accreditation advertisements can be seen almost everywhere. In everyone’s impression, such advertisements for accreditation correspond to fake documents, just like the case cracked by Nantong police. However, the "Legal Daily" reporter found that in the accreditation business, some businesses claimed that they could provide "genuine" professional qualification certificates.

　　□ Our reporter Han Dandong

　　□ Intern Li Wenguan of this newspaper

　　Han Lin, who is studying at Tianjin Normal University, has been struggling recently. Seeing that she will graduate next year, she hasn’t got a teacher’s qualification certificate so far because Mandarin is not enough, which has a great impact on finding a job.

　　There are two choices before Han Lin, either practicing Putonghua hard and taking the exam again, or spending money to get a Putonghua grade certificate. "Compared with the two, the risks are the same." Han Lin said, "if you take the exam again, you may still fail;" Spend money to apply for a certificate, although the other party promises to inquire, but I don’t know whether it is true or not. "

　　Han Lin told the reporter of Legal Daily that it is almost an open secret among the students to spend money on the real certificate that can be inquired through official website. According to her understanding, in addition to the teacher qualification certificate, legal professional qualification certificate and other certificates can not be bought online, some professional qualification certificates, such as Putonghua grade certificate, health certificate, nutritionist and other certificates can be bought online, "it is said that it can also be found on official website".

　　According to the regulations, applicants need to take the corresponding exams and meet the standards before they can obtain the qualification certificate. Does it really exist that you can get a qualification certificate without taking an exam and be able to query through official website? The "Legal Daily" reporter launched an investigation on this.

　　3,500 yuan to run the Putonghua Grade Certificate.

　　For those who want to engage in the teaching profession, the Putonghua grade certificate is a necessary document. However, some people miss out on the teaching position because Mandarin is not up to standard, such as Zhou Wei.

　　Although I majored in education in college and always wanted to be a teacher, Zhou Wei has been unable to apply for a teacher position. "Because my Mandarin is not enough, I can’t take the teacher qualification exam, so I can’t apply for a teacher. Now I can only do some non-teaching work in some small training institutions."

　　Zhou Wei said that the failure of Putonghua has always bothered her, so she paid attention to all kinds of information about the Putonghua exam. At the beginning of this year, when she inquired about relevant information, she found that an online shop was selling Putonghua Grade Certificate, and it could be inquired through official website. "I chose a good online shop. The store said that 3,500 yuan can be used for a first-class and second-class certificate of Putonghua. Pay the deposit of 600 yuan first, and it can be done in two months. After another month, you can check online, and you can pay the final payment after the inquiry. " Zhou Wei said, "At that time, I tentatively asked if I could directly apply for a teacher qualification certificate. The store’s statement is that it is too difficult to apply for a teacher qualification certificate. "

　　Holding the psychology that "a dead horse is a living horse doctor", Zhou Wei paid the store a 600 yuan deposit. Two months later, the first-class and second-class certificate of Putonghua was sent to Zhou Wei. About a week later, the store told Zhou Wei that she could inquire. Zhou Wei logged into the national Putonghua training and testing information resource network and found that both scores and certificates could be found. Zhou Wei then clicked on the online store to confirm the payment.

　　With the experience of handling Putonghua Grade Certificate, Zhou Wei took advantage of the opportunity to spend money to buy a second-class computer certificate. "I checked, and there is no problem."

　　Online shopping level 4 chef’s certificate can be queried online.

　　Liu Jun, from Lanzhou City, Gansu Province, also told reporters about his experience of buying a certificate.

　　In July this year, Liu Jun learned from a friend that he could buy a certificate. After that, he searched for an online shop with a permit business on an e-commerce platform.

　　"I’m a good cook. I’ve always wanted to get a chef’s certificate. I just tried it that time." Liu Jun told reporters that after he told the online shop owner about the need for a chef’s certificate, the other party said that there was no problem, and he only needed to provide a 1-inch ID photo and a photo of the front and back of the ID card. He sent the photos to the other party’s mailbox as requested by the other party.

　　"The shopkeeper said that the first cooperation was a sign of sincerity, and payment could be made after the certificate was completed. It will take about two months to get the certificate. Official website needs to wait for a month or so after the certificate is completed. " Liu Jun said.

　　On September 21st, Liu Jun received a photo of the certificate from the owner of the online shop. "What is shown above is my personal information. The column of occupation (type of work) and grade is filled in as Chinese Cooker Level 4. The score of theoretical knowledge test is 67, and the score of operational skills test is 68, and the evaluation result is qualified." Liu Jun said that the certificate was issued on September 14th, 2017. At that time, official website still couldn’t find it. The owner said that online inquiry will have to wait for about a month.

　　On November 10th, Liu Jun received a notice from the owner that the previous certificate had been online. Liu Jun inquired online according to the information of the photos he had received before, and information such as personal basic information and test scores appeared on the webpage, which was exactly the same as the information on the certificate. The data was reported on November 7.

　　Subsequently, Liu Jun forwarded the previously agreed 400 yuan to the other party via WeChat, and sent the address to the other party. The owner said that it would be mailed as soon as possible and paid by SF Express. On November 13th, Liu Jun received the documents mailed by the other party.

　　Liu Jun showed the reporter this "real certificate" purchased from the Internet. The reporter saw that the official seal of the issuing authority on the left side of the certificate is the special seal for the appraisal of the Human Resources and Social Security Bureau of a city in Jiangxi Province, and the special seal for the professional skill appraisal of occupational skill testing authority of a city in Jiangxi Province on the right side of the certificate, with the words of steel seal clearly visible.

　　Customer service reminds me to search for official website query by myself.

　　Is Zhou Wei and Liu Jun’s experience of buying securities a case or a market?

　　On an e-commerce platform, the reporter of Legal Daily searched for the keyword "certificate", and thousands of products appeared in the query results. However, the query page says "training" and "certificate holster, diploma qualification certificate driver’s license shell … …”

　　"Legal Daily" reporter entered an online shop, which opened in 2009, with a favorable rate of more than 98%. The owner of the online shop wrote in the statement: "Chengzheng Studio undertakes all kinds of complicated certificates, five-star service, fair price, professional technology, advanced equipment, quick delivery and your satisfaction are the driving forces for us to continue. Welcome everyone to come! Registration process: consult and confirm the registration materials submitted for the registration course and pay the registration fee. After checking the certificate, pay the final payment SF mail certificate. "

　　The "Legal Daily" reporter opened the online consultation window of the store, and the other party directly asked: "What certificate do I need to apply for?" The reporter asked if he could apply for a welding certificate, and the customer service quickly replied "Yes" and introduced the price of each certificate to the reporter.

　　The "Legal Daily" reporter asked the store owner how to pay for all the treasures in the online store. The customer service said that after discussing the price of the certificate, just shoot the baby in the certificate shell directly. The price of the certificate shell is 10 yuan, so you can shoot more babies according to the certificate price.

　　Subsequently, the reporter of Legal Daily searched with "professional qualification certificate" as the key word, and there was no need to filter. The search results all read "professional qualification certificate, human resource manager level 1, level 2 and level 3". The reporter clicked into an online shop named "Yimei Culture and Education Center". Just entering the online store, the customer service staff asked the reporter what certificate he needed to apply for. The reporter asked if he could apply for a chef’s certificate. The customer service replied: "Yes, you need to provide one-inch or two-inch recent photos (blue or red background, white background) and a copy of your ID card. You can only apply for intermediate or advanced, intermediate 780 yuan, and advanced 1,280 yuan. The intermediate certificate will be issued in about two months, and the advanced certificate will be issued in three or four months. After the certificate is issued, it will be queried on the national website in two months."

　　The reporter asked how to ensure the authenticity of the documents. The customer service immediately said, "It’s impossible for a fake certificate to come down for that long. It’s good to make a fake certificate for a few days. Besides, you have to go to jail for making a fake certificate. If you don’t believe it, you can wait until you find it before confirming the receipt. "

　　After listening to the introduction of customer service, the reporter said that some inquiry websites are fake now. The customer service reminded the reporter that you should not use the website that the merchant gave you to inquire, but directly search for the national vocational qualification certificate from the Internet, and inquire from the regular official website. "The real certificates are all checked about two months after the issuance of the certificate, and the national inquiry system is updated regularly, so it is impossible to check the certificate."

　　Online shop trading cycle is consistent, but prices are different.

　　In an online shop named "Jiangxi Textual Research Network", the reporter of "Legal Daily" just clicked on the chat page, and the other party suggested that the reporter contact by phone or WeChat. The reporter added a WeChat according to the mobile phone number provided by the other party, and this is called "Jiangxi Textual Research Studio — — Teacher Li’ s people started to communicate. The reporter asked what documents he could apply for, and "Teacher Li" said that he could only apply for some professional qualification certificates, and guaranteed that they could be checked.

　　An online shop named "Macy’s University Hall" opened on October 11th, 2004, with a favorable rate of 99.44%. It is located in Nanjing, Jiangsu. When entering the store, there are three points for attention on the home page: special goods, once sold, will not be returned, please know; All trainees who have been trained by this institution shall ensure to get the vocational qualification certificate recognized by the state; All certificates can be checked for permanent registration, which can be checked in this life and in the next life. At the bottom of the page, the optional certificates include 10 categories, such as business services, electronic information and building electrician.

　　The "Legal Daily" reporter inquired about a number of online stores on an e-commerce platform. The shopkeepers’ caliber was almost the same, and they all guaranteed to issue certificates in two or three months. After issuing certificates, they could check online for two months. Most of them traded by paying the deposit first and then paying the final payment. The materials needed to apply for certificates are almost the same, mostly photos and copies of ID cards, and some need to fill out a form, including the name, age, education and other basic information of the applicant. The prices of these documents vary. Take the intermediate vocational qualification certificate as an example. Some merchants ask for three or four hundred yuan, while others ask for seven or eight hundred yuan, all of which promise to be checked for life.

　　Vocational skill appraisal institutions organize examinations.

　　According to the regulations, what are the procedures for applying for vocational qualification certificates?

　　According to a staff member of the Business Department of the Human Resources and Social Security Bureau of Lanzhou City, Gansu Province, citizens who want to obtain vocational qualification certificates should register at the vocational skill appraisal institute first. Vocational skill appraisal institute is established with the approval of personnel department, and every district in Lanzhou has vocational skill appraisal institute. After the registration, the vocational skill appraisal institute first examines the qualifications of candidates, including age, whether the education is appropriate, and the type of personnel, such as students or social workers. After the vocational skill appraisal institute examines the qualifications of the registered candidates, the Municipal People’s Social Security Bureau will conduct further qualification examination, mainly to see whether there are conditions for entering the examination. In the third step, the vocational skill appraisal institute needs to do preparatory work before the exam, such as printing the admission ticket. These are all audit links, and they are also the work that needs to be done in vocational skill appraisal. The fourth step is to organize the candidates’ examination by the vocational skill appraisal institute. After the candidates get the admission ticket, they will take the examination according to the time and place specified in the admission ticket. At the end of the exam, the vocational skill appraisal institute will score and score, and it will be qualified if it reaches 60 points or more. After that, the vocational skill appraisal institute reported the data of qualified candidates to the Municipal People’s Social Security Bureau. The Municipal People’s Social Security Bureau will further review various information such as candidates’ grades and ages. After the examination and approval by the Municipal People’s Social Security Bureau, the data of qualified candidates will be reported to the provincial appraisal center. After the final review, the provincial appraisal center will inform the Municipal People’s Social Security Bureau of the results, and one who is qualified will be given an empty certificate, and then the Municipal People’s Social Security Bureau will fill in the information and finally issue the certificate.

　　According to this staff member, the examination was organized by the Vocational Skills Appraisal Institute. During the examination, the Municipal People’s Social Security Bureau organized personnel to conduct on-site inspections. For the examination papers, the Municipal People’s Social Security Bureau should also organize personnel to conduct spot checks, and the workload of the census is too great.

　　So, what is the vocational skill appraisal institute?

　　The reporter inquired that both the vocational skill appraisal institute and the human resources service intermediary agency applied to the municipal human resources department or the provincial human resources department for establishment.

　　Article 69 of the Labor Law of People’s Republic of China (PRC) stipulates: The state determines the occupational classification, sets the vocational skill standards for the specified occupations, and implements the vocational qualification certificate system, and the assessment and appraisal institutions approved by the government are responsible for the assessment and appraisal of workers’ vocational skills.

　　Paragraph 2 of Article 26 of the Law of People’s Republic of China (PRC) Municipality on the Promotion of Private Education stipulates that students who have received vocational skills training and passed the appraisal by vocational skill appraisal institutions approved by the government may be issued with national vocational qualification certificates.

　　How to apply for the establishment of a vocational skill appraisal institution? The reporter inquired about the information and found that the conditions for accepting the identification of vocational skill appraisal institutions by local human and social departments are almost the same. Taking Tianjin as an example, the application conditions are as follows: vocational skill appraisal institutions should meet the basic conditions stipulated by national laws, regulations and policies; The sponsor shall have the legal person qualification; Having a clear name, organization and articles of association; There are full-time and part-time assessors; Having the purpose, objective and outline of appraisal; Equipment and facilities meet the prescribed standards; The registered capital reaches the prescribed standard; There are venues that meet the needs of identification.

　　Cartography/Li Xiaojun

　　In the past few days, a screenshot poking fun at domestic refined oil prices has been widely circulated in the circle of friends:

　　"Ten years ago, on March 20, 2008, the international crude oil was $147 per barrel, and the domestic oil price was 6.3 yuan; Ten years later, on May 26th, 2018, the international crude oil price was $75.56 per barrel, and the domestic oil price was 7.4 yuan. Maybe the bucket is expensive. "

　　In fact, since the international oil price plummeted in the second half of 2014, similar paragraphs have emerged one after another. From a purely numerical point of view, today’s international oil price is indeed lower than that of ten years ago, and the domestic refined oil price is indeed higher than that of ten years ago. However, the pricing mechanism of refined oil in China is not as simple as many people think, especially when the consumption tax on refined oil has increased by nearly seven times. It is unreasonable to simply compare the figures. To discuss the comparison of oil prices between 2008 and today, we need to consider the following factors:

　　petrol quality upgrade

　　In 2008, private cars still drank the national standard gasoline, and today it is the national standard gasoline ten years later. The "2+26" cities including Beijing, Tianjin and Hebei have been upgraded to the national standard in advance. When oil products are upgraded, prices naturally rise. According to the statistics of Zhuo Chuang Information, a market organization, the price increase standards for automobile gasoline and diesel from the third country to the fourth country are 290 yuan and 370 yuan per ton respectively; The price increase standards for upgrading from National IV to National V are respectively 170 yuan and 160 yuan per ton. That is, the total price of gasoline is increased by 460 yuan/ton, which is equivalent to the price increase of No.92, which is 0.36 yuan.

　　The consumption tax on refined oil has increased by nearly seven times.

　　The consumption tax on refined oil refers to the tax paid by consumers when they consume refined oil. It is paid by the main units such as refineries at the initial stage of production, commissioned processing and import. The collection targets include seven subheads, including gasoline, diesel oil and fuel oil, which belong to the central tax category. China began to levy consumption tax on gasoline in 1994. In 2008, the domestic consumption tax on gasoline was only in 0.2 yuan/liter.

　　From the end of 2014 to the beginning of 2015, the domestic consumption tax on refined oil was raised three times in 45 days. At that time, the Ministry of Finance said that the consumption tax in China is not generally levied, but only on "some consumer goods with high energy consumption, high pollution and high consumption". "The consumption tax on refined oil is conducive to promoting resource conservation and curbing excessive consumption of energy, which is a relatively common practice in the world." Regarding the timing of raising the tax rate, the Ministry of Finance explained that "choosing to implement it when the oil price goes down not only did not lead to an increase in oil prices due to tax increase, but also realized the synchronization of tax increase and price reduction, taking into account the macro-control needs and social affordability."

　　After three upward adjustments, the gasoline consumption tax was 1.52 yuan/liter, which has been maintained to this day.

　　In addition to consumption tax, China consumers also need to pay value-added tax and urban construction tax when purchasing refined oil. It is roughly estimated that the tax burden cost of circulation links accounts for about 40% of the total refined oil price.

　　"At present, domestic refined oil products include 1.52 yuan/liter consumption tax, 16% value-added tax and 12% other taxes and fees. Due to the different oil prices in different regions of China, the proportion of taxes and fees is also different. " Xu Na, a refined oil analyst at Zhuo Chuang Information, told The Paper (www.thepaper.cn) that the current price of No.92 gasoline in Guangzhou is 7.44 yuan/liter, including 1.52 yuan/liter consumption tax, 1.03 yuan/liter value-added tax and 0.31 yuan/liter other taxes. Therefore, on the whole, the price increase of Guangzhou No.92 gasoline includes 2.86 yuan tax, accounting for 38.4%.

　　In addition, the tax burden of refined oil products in different countries in the world is not horizontally comparable, because the tax burden is related to national policies, oil production capacity, per capita income level and social welfare.

　　Changes of refined oil pricing mechanism

　　Ten years ago, there was no price adjustment cycle for domestic refined oil products, which was not closely related to international oil prices.

　　The current refined oil price mechanism stipulates that the prices of gasoline and diesel are adjusted every 10 working days according to the changes of crude oil prices in the international market, and the effective time of price adjustment is 24: 00 on the release date of price adjustment. As long as the international oil price is between the "floor price" of $40/barrel and the "ceiling price" of $130/barrel, the change rate should be adjusted if the adjustment range of gasoline and diesel exceeds that of 50 yuan. When the price adjustment range is lower than the 50 yuan per ton, no adjustment will be made, and it will be added or offset in the next price adjustment.

　　Because of this, after the international crude oil price soared to an all-time high of $147 per barrel in 2008, the domestic refined oil price did not rise as the international oil price soared. For the smooth operation of the domestic economy, domestic "two barrels of oil" did "pay the bill" for high oil prices.

　　At the beginning of 2015, a paragraph about oil prices was widely circulated on the Internet: "Today (March 20th) is a special day. Seven years ago, today in 2008, the international crude oil was $147 per barrel, and the oil price in China was RMB per liter in 6.3 yuan. Today in 2015, the international crude oil is 43 dollars per barrel, and the China oil price is still 6.3 yuan RMB per liter. Is the oil price going up or down? " Just a few words have attracted countless spit and controversy.

　　In this regard, Sinopec claimed to be "the big head" in the official Weibo: "Today (referring to March 21, 2015), the international crude oil is 43 US dollars per barrel, and the EU is about 9.1 yuan and China is about 6.3 yuan per liter. Seven years ago, today in 2008, due to the economic situation in China and the pressure from all sides, the price adjustment of domestic refined oil was reduced. The international crude oil was US$ 147 per barrel, while the EU was about RMB 14.8 per liter, while China was only 6.3 yuan per liter. Who is ‘ Big head ’ , you know. "

　　The following figure shows the global ranking of gasoline price increase as of May 28, 2018 (part):

　　"If you are in politics, you will be governed by the feelings of the next, and if you can’t, you will be chaotic." An important aspect of keeping close contact with the masses is the trend of investigation and research in Daxing.

　　— — Speech by the Supreme Leader at the Party Building Work Conference of Central and State Organs (July 9, 2019)

　　"When you are in power, you will be governed by the emotions, but if you are not in power, you will be in chaos." The language Mozi Shang Tong means that politicians should fully grasp the emotions and public opinion before they can manage the society well, otherwise it will easily lead to chaos. To understand the next situation, we must sink down to the people in a down-to-earth manner.

　　In the Ming Dynasty, there was an official named Zhou Chen who liked to "go into the fields, talk to the villagers and ask about their sufferings". One night, Zhou Chen passed by a village and saw villagers enjoying the cool under the tree, so he took the initiative to talk. It was not until the subordinates found it that the villagers knew that the person in front of them was actually the governor of Jiangnan. In this way, "every time I sit in one place, I am afraid that it will not be exhausted." Zhou Chen learned a lot of local facts through face-to-face conversations with the people.

　　Later, Zhou Chen founded the "square meter law" and reduced the rent of grain from official land, which reduced the burden on the people and solved the problem of tax arrears. He insisted on consulting the people, and many reform strategies came from research. People commented: "Every time Zhou Wenxiang made a revolution, he would oppose reconsideration with officials and scholars. For example, if you elaborate a method, you will call Dongmen huangpo into the platform and often leave a message until midnight. "

　　"The feeling of winning" can not only know "the hardship of farming" and "the hardship of spinning performance", but also serve as an important basis for scientific decision-making. Historically, Shang Yang’s "a strong country knows thirteen numbers" and the two tax laws of the Tang Dynasty were all strategies for governing the country after in-depth investigation.

　　Wang Zhiwang, an official in the Southern Song Dynasty, was the first person who conducted a large-scale public opinion survey in ancient China and revised the national tax policy on this basis. At that time, in view of the uneven land tax and chaotic taxation, the Southern Song government decided to clear the land and rectify the taxation, and introduced the "Economic Boundary Law", but there were great differences among the people. Wang Zhiwang realized that "the matter is the most important, the opinions are different, the interests are suspicious, and I dare not judge by partiality." So, he began to make a comprehensive survey.

　　Wang Zhiwang asked his subordinates to go door-to-door to see how many people supported the old tax law and how many supported the new tax law, and then summarized and analyzed them. This time, a total of 9 States, more than 30 counties and more than 330,000 households were involved, and the amount of work was huge.

　　According to the investigation results, Wang Zhiwang revised the tax reform plan and submitted "On the Management of Tongchuan Road" to the court. In the memorial, he emphasized the different opinions of the people in different States on the "Jing Jie Law": "There are many people in the four States of Huai An Army in Changrong, and there are few people in Fushun Supervision in Suining, Tongchuan." This solid memorial provided a reliable basis for the improvement of the imperial policy.

　　Paying attention to observing people’s feelings and advocating investigation and research are important contents of China’s traditional political culture. In the Western Zhou Dynasty, poetry collectors went to various places to "observe customs and know gains and losses". Some people said that the Book of Songs was an ancient investigation report. Guan Zi Wen puts forward dozens of questions to be asked, which is considered as "the oldest and most comprehensive outline of social investigation". All dynasties have established various patrol systems, which play an important role in reaching the next level.

　　Compared with ancient times, today’s means of transportation and communication are more and more developed, and there are more and more channels to obtain information, but the convenience of technology also brings some problems. For example, some cadres would rather sit in the office and read all kinds of data and collect research reports on the Internet than go to the grass-roots level to dip their legs in mud and stand in the field to chat with the people. This kind of "paper" research can’t get the real situation at all, so how can we formulate policies on this basis?

　　Liu Xiang said in Shuo Yuan Zheng Li in the Western Han Dynasty: "What you hear is not as good as what you see, what you see is not as good as what you practice, and what you practice is not as good as what you distinguish by hand." In order to grasp the truth, leading cadres must carry out hands-on investigation and study, and go to the front line to see, listen, ask and think by themselves. This is a working method and an official style.

He got up early as usual two days ago, ready to have breakfast and go out for a walk, but he didn’t expect to go out, about 6: 30. Suddenly, the whole person’s left limbs, including arms and legs, lost their strength, were out of control, and began to walk erratically, so he rushed to the hospital for consultation.

The attending doctor of neurology department made a physical examination for Mr. Wu and found that his left limb muscle strength was grade 3. Combined with clinical symptoms and medical history, it was preliminarily judged to be acute cerebral infarction.

What is a stroke? !

Stroke includes ischemic stroke and hemorrhagic stroke, in which ischemic stroke accounts for 60-70%.

If the human brain is compared to a field, the blood vessels in the brain are irrigation ditches in the field.

How to identify stroke?

Remember "120 recipes for stroke"

1. In case of signs of stroke, you should dial 120 quickly and send it to the nearest green channel hospital, bearing in mind that "time is life".

Briefly describe the patient’s situation and illness, accurately describe the location, and let the emergency doctor prepare for the rescue and arrive at the emergency site as soon as possible.

2, be sure to keep breathing unobstructed. If there is vomiting, lie on your side and tilt your head to one side, unbutton the patient’s coat, and remove foreign bodies in your mouth, such as dentures and vomit. If the patient snores like thunder, it means that there is poor breathing. Lie on your side or put your neck up and your head back.

3. Don’t take medicine by yourself. Stroke can be divided into hemorrhagic and ischemic types. The treatment methods are different. If you take medicine at will when you are not diagnosed, it may aggravate your condition.

4. Don’t sit up straight, and don’t hug, drag, carry or carry the patient.

In the process of patient transfer, it is best for family members to respect the advice of emergency doctors and avoid choosing to transfer by car or taxi.

Healthy lifestyle

Is the basis of disease prevention.

1. Quit smoking and limit alcohol

Smoking is an independent risk factor for stroke, especially for ischemic stroke. Smoking accelerates arteriosclerosis and increases the probability of thrombosis; Passive smoking is also harmful.

For non-drinkers, drinking is not recommended to prevent cardiovascular and cerebrovascular diseases.

2. Exercise properly

Moderate exercise: such as walking, jogging, cycling, or other aerobic metabolism fitness activities; The best exercise time is 4-5 pm, followed by evening (2-3 hours after dinner), and you can do light exercise in the morning. It is recommended to have moderate physical activity of ≥ 30 minutes every day, at least three times a week.

3. Lose weight

Overweight and obese people can reduce their weight and the risk of stroke by adopting healthy lifestyle and increasing physical activity. Advocate a healthy lifestyle and good eating habits.

4. Reasonable diet

Formula of reasonable diet: eat fruit first and then eat, a vegetarian meal every day, one catty of milk, one egg, three kinds of fruits, limited salt, less oil and more vegetables, and coarse grains flour and rice alternately, so as to keep health.

5, regular screening

Routine blood tests (platelet, coagulation function, etc.); Blood pressure, blood sugar and blood lipid examination; Transcranial Doppler examination and other vascular function tests; Examination of brain tissue lesions and blood flow.

Common stroke

Misunderstanding

Wrong: ① transfusion twice a year, which can prevent middle disease; ② If the blood pressure is normal or low, you won’t get a stroke; (3) only the elderly will have a stroke, and thin people will not have a stroke; ④ One month after stroke, it will be better; ⑤ Listen to advertisements and be superstitious about high-priced drugs and specific drugs; ⑥ Health products can soften blood vessels and lower cholesterol.

Correct: ① More than 80% of strokes can be prevented, but transfusion prevention is not scientific; ② People with normal blood pressure may get sick due to other factors; ③ People of all ages, whether fat or thin, may occur; ④ Rehabilitation treatment is needed, otherwise it may be impossible to recover for life; ⑤ Go to a regular hospital for corresponding treatment; ⑥ Most health care products have no effect on preventing and treating diseases.

On May 12th, OPPO announced that it would completely terminate the business of its chip design company ZEKU, which also triggered a huge shock in the industry.

There are also different opinions about why Zheku Technology was suddenly dissolved without warning.

The official reason given by OPPO for dissolving Zheku is "the uncertainty of global economy and mobile phone market".

Liu Jun, CEO of Zheku, also said at the last general meeting: "The global economy and mobile phone industry are extremely pessimistic now, and the company’s entire revenue is far from expectations. So in this case,Such a huge investment in chips will be beyond the company’s affordability.So I regret to make an announcement here. After careful discussion, the company decided to shut down Zheku and terminate the chip self-research business. As CEO of Zheku, I couldn’t take this business to the place we wanted to go, and it’s a pity to tell you in this way. At this time, I can only say, I’m sorry, thank all Zheku colleagues, and thank them for their hard work in Zheku over the past four years. "

Indeed, since last year, the global economic situation has declined and the smartphone market has continued to shrink, which has also put tremendous pressure on OPPO.

According to IDC data, in 2022, global smartphone shipments fell by 11.3% year-on-year, and OPPO shipments were 103.3 million units, down by 22.7% year-on-year. Moreover, the smartphone market is still in a downward trend, and the recovery may have to wait until the second half of the year.

From the current point of view,OPPO has been mass-produced and shipped MariSilicon X. Although it has been adopted by the high-end versions of Find X5, X6 and Reno9 series, the shipment volume is still relatively limited, which may not cover its research and development costs.

This also makes the outside world think that it is because Zheku burned too much money (it is rumored that it burned 50 billion yuan in three years, but it is not so much), and the continuous decline of the global economy and smartphone market since last year has brought greater pressure to OPPO. OPPO finally decided to give up.

However, this explanation seems reasonable, but it is puzzling. becauseIn fact, Zheku has spent less than 10 billion yuan in more than three years since its establishment, and OPPO is not short of money now. Even if you think that self-developed chips burn money, it is entirely possible to reduce Zheku’s product line and focus on some areas you need (such as power management chips).

Just in February this year, Liu Zuohu, senior vice president and chief product officer of OPPO, also publicly disclosed the SUPERVOOC S full-link power management chip developed by OPPO, and said that in the future, OPPO and all models with charging power above 100W will be equipped with Supervooc S.

The compensation scheme is very kind and OPPO is not short of money.

Judging from Zheku’s compensation for layoffs, it can be said that it is very generous. The compensation standard for regular employees in China is "N+3", and the base is the total annual salary+bonus+all other income divided by 12. And in May, salary will be paid according to one month, and social security will be paid for employees in May.

Even fresh graduates who fail to report for duty can get compensation of (offer’s monthly salary+bonus /12) *3. It can be said that the whole compensation scheme is very kind.

According to the data, Zheku was established in August 2019, covering product lines including: core application processor, short-range communication, 5G Modem, RF, ISP and power management chip. At present, the team totals about 3000 people.

According to reports, since its establishment, Zheku Technology has always been a big and high-paying poacher, which also makes the average salary of Zheku Technology significantly higher than the industry average.

According to the statistics of the Staff Friends Group, the average salary of Zheku Technology is 44,504 yuan/month, of which 2.3% is 20,000-30,000 yuan, 45.6% is 30,000-50,000 yuan, and 51.1% is above 50,000 yuan.

If calculated according to the average monthly salary of about 45,000, the "N+3" compensation for 3,000 people will exceed 405 million yuan. If you want to calculate the year-end bonus and other income equally in the compensation base, I’m afraid it will be about 500 million yuan.

OPPO said thatAll these compensations will be paid within 5 working days after signing the resignation agreement before May 19th.This also shows that OPPO is not short of money at this stage.

On May 13th, Shen Yiren, former vice president of OPPO, said in the Weibo, "What money can solve is actually not a big problem … … The problem that money cannot solve is the real problem. "

Therefore, the real reason why OPPO suddenly disbanded Zheku Technology is not simply the problem of "money".

How much did Zheku "burn"? Maybe less than 10 billion

As early as the Future Science and Technology Conference in 2019, Chen Mingyong, founder and CEO of OPPO, announced that "50 billion yuan will be invested in R&D to build a technical moat in the next three years", and then OPPO officially launched the Mariana Plan for self-developed chips. This also shows that OPPO has made plans for a protracted war before opening the self-developed chip, and has given sufficient funds.

Although there are many rumors on the Internet that "Zheku burned 50 billion yuan in three years", in fact Zheku may only spend about 10 billion yuan.

Even according to the current scale of 3,000 people, the annual salary consumption is about 2 billion yuan (calculated according to the previous estimate of 500 million yuan for three months).

Although Zheku was established in August 2019, it has been more than three years since it really started to develop chips. The annual salary costs 2 billion yuan, which is about 6 billion yuan in total.

Moreover, the team of 3,000 people has gradually grown up in more than three years. There were not many people at the beginning of the first year, so in fact, the total expenditure on personnel salaries was not 6 billion yuan.

In addition, EDA tools and semiconductor IP needed for chip research and development, as well as chip streaming and mass production are also very expensive.

"The EDA cost of Zheku is about 30 million to 50 million dollars a year."An insider of an American EDA factory revealed to Xinzhixun.

That is to say, in three years, the EDA cost required by Zheku is about 90 million-150 million, which is about 120 million US dollars, or about 835 million RMB.

In terms of streaming cost, the image NPU chip MariSilicon X released by Zheku is based on TSMC’s 6nm process, and the Bluetooth audio SoC chip MariSilicon X is based on TSMC’s N6RF process. In addition, there is a mobile phone AP chip that was previously under development, which is rumored to be based on TSMC’s 4nm process.

According to Xin Zhixun, an insider of a wafer factory knows that the cost of chip streamer is mainly the cost of MASK, which is mainly related to the complexity of chip design. The more metal layers are used, the more mask layers will be, and the higher the cost will be.

Generally speaking, the cost of making a 6nm MASK is about 10 million dollars, and the cost of making a 4nm MASK is about 2,000 dollars.

Because MariSilicon X is a dedicated NPU chip, MariSilicon is an audio SoC, but its complexity is far less than that of mobile phone AP. Therefore, the actual mask cost required for these two chips is expected to be lower.

Even if the conventional cost is estimated, the total cost of the three chips (calculated according to the success of one tape) is about 40 million dollars, or about 278 million yuan.

As for the IP licensing fee required for each chip project, because most of the IP of MariSilicon X and MariSilicon Y are self-developed, the cost of semiconductor IP to be outsourced is not high, which is estimated to be around several million dollars, so let’s calculate 10 million dollars in Dali, which is about 70 million yuan.

The rumored mobile phone AP is a eight nuclear CPU+10-core GPU, which uses Arm’s Cortex-X2+Cortex-A710+Cortex-A510 CPU IP, and the GPU IP should also belong to Arm, which will make the IP cost of this mobile phone AP soar.

According to insiders, the Arm IP cost for such a 4nm AP chip may need 30 to 50 million dollars, and other IP types may also need 30 to 50 million dollars. According to the median calculation, it is about $80 million.

Therefore, the total IP licensing fee for the three chips may be about 90 million dollars, or about 626 million yuan.

Taken together, Zheku’s three-year staff salary, EDA tools needed for chip research and development, the purchase of semiconductor IP, and the cost of chip streaming are probably less than 7.8 billion yuan.

Even if other expenses such as office rent, all kinds of office equipment, test equipment, servers, water and electricity network fees, and supporting employee benefits are included, how to calculate 10 billion yuan should be enough.

Obviously, the expenditure of 10 billion yuan is far from Chen Mingyong’s psychological budget of "investing 50 billion yuan in research and development in three years".

4nm AP slide failed?

For the reason why OPPO gave up Zheku, there are rumors that the 4nm mobile phone AP is too difficult, and the streaming failed. In the future, more money may be needed to succeed, and even if it succeeds, it may not be recognized by the market, so it is decided to give up.

However, an internal employee of Zheku confirmed to Xinzhixun that,This AP has not failed, "bing up and all kinds of follow-up work are being prepared internally". According to the previous forecast, the film will come back in mid-June, and now no film has come back for testing. How do you know it has failed?

Liu Jun, CEO of Zheku, also stressed at the last general meeting:"This decision has nothing to do with the quality of your work."

Obviously, the sudden dissolution of Zheku is not due to the "4nm AP film failure".

The supporting MediaTek 5G baseband was stopped

Although Zheku’s mobile phone AP doesn’t have its own baseband chip, it can realize the 5G communication function by plugging in a third-party 5G baseband chip, just like Apple A series processors.

According to Xin Zhixun’s understanding,This mobile phone AP was originally planned to plug in a 5G baseband chip supplied by MediaTek.

According to an internal employee of Zheku, Xin Zhixun revealed that,Last week, MediaTek was still solving the problems related to Zheku Baseband, and Zheku suddenly announced its dissolution, which also caught the other side off guard.

Because the existing 5G baseband chips in MediaTek cannot be directly used, they need to be customized according to the AP design and needs of Zheku.

People in the semiconductor industry @ 中中中中中中 also broke the news yesterday.Affected by the closure of Zheku, the 5G baseband plan matched with MediaTek also stopped, and the 6nm/4nm RF/AP WIP (work in process) on TSMC production line was also stopped.

As Zheku suddenly announced its closure, the cooperation with MediaTek has been unilaterally terminated, and it is expected that it may also need to pay a large amount of "liquidated damages".

Summary:

Based on the above analysis,The sudden closure of OPPO without warning seems to be not because Zheku’s "burning money" exceeded expectations, nor because OPPO has no money, nor is there a problem with Zheku’s product development.

So, what caused OPPO to suddenly give up developing its own chips and disband the 3,000-person Zheku team at any cost, so that all the efforts of this group of excellent chip designers in China in the past four years were wasted? I am afraid that most of the existing research and development results will also be abandoned.

Duan Yongping, the founder of BBK brand, left a meaningful comment when evaluating the news of Zheku’s closure on snowball:"Correct mistakes as soon as possible, no matter how much it costs."

Duan Yongping’s implication seems to be that the OPPO self-developed chip was a mistake from the beginning, but if it was a mistake from the beginning, why did it take nearly four years to point it out?

In the past two days, many media and analysts have given such views "with hindsight", but why did these people go early?

Generally speaking, there are some "puzzling" places in OPPO’s sudden dissolution of Zheku, especially in the context of the continuous suppression of the domestic semiconductor industry in recent years. It is no wonder that many netizens believe that the main reason is OPPO’s deep "fear" of that "mysterious force".

After all, the mobile phone business is only one of its three major businesses, compared with another company that has been repeatedly hit by "mysterious forces" but has not fallen. OPPO’s business is more single. Once the mobile phone business is affected, there will be no other business to transfuse blood. The "spare tire" is still under development, and of course there is no chance of "turning positive".

However, regarding this view, a Zheku executive told Core Intelligence:"Conspiracy theories cannot be falsified, so people always like to listen."

Finally, I borrow a passage from Wang Zhuo, the head of Zheku baseband and RF department, at the general meeting as the end of this article, and wish my friends who have worked in Zheku a new job in the future and continue to fight for the rise of China Core!

"Zheku no longer exists, so Zheku may be meaningless in itself, but the journey we have traveled together is meaningful. … … As long as we have made efforts, God will surely see it. I believe that all our efforts will not be in vain, and you will definitely see his help to you at some point. "
