Banquet also has skills. Nanjing experts teach you "the art of ordering food"

  Recently, @ People’s Daily published a message saying that the People’s Social Welfare Department of Sichuan Province has published 294 professional competence assessments, one of which is Sichuan cuisine. In this regard, some netizens said: "For foodies, ordering food can be verified. Isn’t this card a piece of cake?"

  In modern society, the banquet is no longer a simple meal, there are a lot of knowledge and attention. A proper menu can increase communication between people in private and promote negotiation and cooperation between business partners in public. However, nowadays, most people don’t like to order food. At the dinner table where people gather, who will order food has become a headache.

  Near the Mid-Autumn Festival and National Day, family dinners, friends’ gatherings and business receptions will inevitably go to restaurants to order food. Zijinshan reporter interviewed the heads of some old restaurants in Nanjing to tell you about the "art of ordering food" in old Nanjing.

  Why is ordering important? Yuan Mei told the truth more than two hundred years ago.

  Why do Sichuan food orderers need to set up special professional ability assessment? According to relevant media reports, an excellent Sichuan dish ordering staff should not only simply write down the dishes ordered by the guests, but also put forward optimization suggestions for the dishes ordered according to the requirements of different types of guests.

  Zhang Zhijun, deputy general manager of Gunudu Group, told Zijinshan that taste is the core of the banquet, and if it is not properly matched, it will give people a monotonous feeling. If the table is full of salty dishes, it will make people feel dull. However, if a banquet is dominated by five or six spicy dishes, it will be too exciting and even uncomfortable. Therefore, a banquet must have ups and downs, and the flavor configuration should be reasonable.

  In fact, Yuan Mei, a "foodie" in Nanjing, summed up how to order food and how to serve it long ago. Yuan Mei wrote in "Menu with the Garden" (published in 1792): "In the method of serving food, salt should be given first, and light should be given later; The rich should be the first, and the thin should be the last; Those who have no soup should be the first, and those who have soup should be the last. Besides, there are five flavors in the world, so we can’t generalize them blindly. When the guest is full, the spleen is sleepy, so it must be vibrated with spicy; If you worry about drinking too much wine, your stomach will be exhausted, so you must use sour and sweet to remind you. "

  Gourmet Xiong Sizhi explained the scientific principle behind this in "The Mystery of Chinese’s Diet": "People’s stomach capacity is limited, and if there is too much food, the hypothalamus will reflect stomach fullness. A variety of foods with strong flavors continue to stimulate the taste buds, and people’s taste will feel tired, and some dishes are very hot. If the tongue temperature is above 60 C or below 0 C, there will be no taste. "

  Paying attention to skills and choosing a good restaurant is the first step.

  There is an old saying in China: everything is established in advance, and it is abolished if it is not planned. A successful banquet needs careful planning. For example, different nationalities have different eating habits and customs, and different regions have different diets. Even different genders and ages will lead to different eating habits. Therefore, it is particularly important to choose a suitable dining place.

  There are eight major cuisines in China, and many people struggle over where to eat every time. Chen Xiaoqing, the general director of the first and second seasons of China on the Tip of the Tongue, said on the program Round Table School: "It seems that people, this is the most important."

  Nanjing White-collar Small House has been docking with major customers all the year round. She summed up a set of reception standards: ordinary customers go to eat Hunan and Sichuan cuisine, important customers go to eat Cantonese and Shanghai cuisine, and especially important customers eat private cuisine.

  "Some customers haven’t become acquaintances. Take them to eat Sichuan food. You can let down your guard and speak freely under the stimulation of hemp and spicy food. Taking important customers to eat Cantonese cuisine and Shanghai cuisine is to discuss cooperation at dinner. These restaurants are generally suitable for business negotiations. Needless to say, especially important customers, taking them to eat private cuisine means that the relationship is intimate to a certain extent. " Xiaoju explained.

  Yan Zhengyu, general manager of Nanjing Anleyuan Restaurant, believes that Nanjing people choose old-fashioned restaurants for family dinners. Old-fashioned restaurants have memories shared by generations at home, which is convenient for emotional exchange.

  In fact, it is not difficult to order food. Just grasp four principles.

  It is not so easy to become a "master of ordering". Zhang Zhijun, who has worked in Nanjing catering industry for decades, knows the way to order food. He said, "It is not difficult to order food. Knowing yourself and knowing yourself can lead to an invincible battle."

  Whether it’s a business banquet or a gathering of friends, for a more formal banquet, as long as the host has time, he might as well go to the restaurant to book the menu first. This is more polite, saves time, and avoids some embarrassment. After ordering, you can also calculate the cost first, so as to know fairly well. If the total price is found to be too high or too low, it can also be adjusted immediately.

  Zhang Zhijun summarized the following four principles of ordering food:

  Look at the theme. According to the theme, click on the "calculating dishes" with rich meanings. General dinners include family dinners, school banquets and birthday banquets. For example, at the school banquet, you can order a dish called "Carp Jumping at the Dragon Gate".

  Second, look at the composition of personnel. If it is a dinner party for several generations, we should give consideration to the age level and order some dishes that are easy to chew and digest for the elderly and children.

  Third, look at seasonal dishes and seasonal dishes. Nanjing people pay attention to not eating from time to time, eating "seven heads and one brain" in spring, crayfish in summer and eight immortals in autumn; From the festival point of view, Nanjing people will eat five reds on the Dragon Boat Festival, and one of them is roast duck. Eight laurel flowers, you can order salted duck at the dinner before and after the Mid-Autumn Festival. On the New Year’s Eve, Nanjing people must order a whole fish and assorted vegetables, which means that there is more than enough and perfection every year.

  Fourth, look at the signature dishes. Time-honored restaurants in Nanjing all have their own specialty dishes, and many specialty dishes also have celebrity stories. If you serve one or two specialty dishes, you can show the host’s care and respect for the invitees.

  There is another way to save trouble. Zhang Zhijun said, "If time permits, you can wait for most of the guests to arrive and circulate the menu in turn, so that everyone can order one dish or several dishes, which will meet everyone’s needs and will not cause waste."

Announcement of the four departments on the specific operational issues related to the implementation of tax policies to support and promote entrepreneurship and employment of key groups

State Taxation Administration of The People’s Republic of China Ministry of Human Resources and Social Security the State Council Poverty Alleviation Office Ministry of Education
Announcement on the implementation of specific operational issues related to tax policies to support and promote entrepreneurship and employment of key groups
State Taxation Administration of The People’s Republic of China Announcement No.10 of 2019

In order to implement the spirit of the Notice of the State Council Poverty Alleviation Office of the Ministry of Finance and the State Administration of Taxation on Further Supporting and Promoting the Entrepreneurial Employment of Key Groups (Caishui [2019] No.22), the specific operational issues are hereby announced as follows:

I. Tax policies for individual businesses of key groups

(1) Application

1. If the poverty-stricken people who set up a file for self-employment are engaged in self-employment, they will enjoy preferential treatment when filing tax returns with the competent tax authorities.

2. Persons who have been registered as unemployed for more than half a year, zero-employment families, registered unemployed persons who enjoy the working age of urban residents’ minimum living guarantee families, and college graduates within the graduation year can apply for the Employment and Entrepreneurship Certificate (or the Employment and Unemployment Registration Certificate, the same below) and the registration license of individual industrial and commercial households (tax registration certificate is required for those who have not completed the "integration of the two certificates") to start businesses at or above the county level (including the county level, the same below). The human resources and social security departments at or above the county level shall verify whether they have enjoyed preferential tax policies for entrepreneurship and employment of key groups in accordance with the provisions of document No.22 [2019] of Caishui. For those who meet the requirements stipulated in Document No.22 of Caishui [2019], please indicate "tax policy for self-employment" or "tax policy for self-employment in graduation year" on the Employment and Entrepreneurship Certificate.

(two) the order and amount of tax relief

If key groups are engaged in self-employment, in accordance with the provisions of Article 1 of Caishui [2019] No.22 Document, within the annual tax reduction and exemption limit, the value-added tax, urban maintenance and construction tax, education surcharge, local education surcharge and personal income tax will be deducted in turn. The tax basis of urban maintenance and construction tax, education surcharge and local education surcharge is the value-added tax payable before enjoying this preferential tax policy.

If the actual operating period of a taxpayer is less than one year, the tax reduction or exemption limit shall be converted by the actual number of months. The conversion formula is: tax reduction and exemption limit = annual tax reduction and exemption limit ÷12× actual operating months.

If the actual value-added tax, urban maintenance and construction tax, education surcharge, local education surcharge and personal income tax payable by taxpayers are less than the tax reduction or exemption limit, the actual value-added tax, urban maintenance and construction tax, education surcharge, local education surcharge and personal income tax shall be limited; If the actual payable value-added tax, urban maintenance and construction tax, education surcharge, local education surcharge and personal income tax are greater than the tax reduction or exemption limit, it shall be limited to the tax reduction or exemption limit.

(3) Tax relief management

Persons who have been registered as unemployed for more than half a year, registered unemployed persons from zero-employment families and urban low-income families, and college graduates who enjoy this tax preference during the graduation year, shall keep the Employment and Entrepreneurship Certificate (marked with "tax policy for starting their own businesses" or "tax policy for starting their own businesses during the graduation year") for future reference, and the poverty-stricken people who have filed a card need not keep information for future reference.

Second, the tax policy for enterprises to recruit key groups

(1) Application

Enterprises that enjoy preferential tax policies for the employment of key groups shall submit applications to the human resources and social security departments at or above the county level with the following materials:

1. "Employment and Entrepreneurship Certificate" held by the recruiter (poverty-stricken people who need to file a card do not need to provide it).

2. The labor contract (copy) signed between the enterprise and the key group, and the social insurance record paid by the enterprise for the key group according to law. Where internal information sharing and data comparison are used for auditing, enterprises may no longer be required to provide social insurance payment records.

After receiving the materials submitted by the enterprise, the human resources and social security department at or above the county level shall focus on verifying the following:

1. Whether the hiring personnel belong to the scope of personnel enjoying preferential tax policies, and whether they have enjoyed preferential tax policies for entrepreneurship and employment of key groups before.

2. Whether the enterprise has signed a labor contract with the recruiter for more than one year, and paid social insurance for the recruiter according to law.

After verification, for the key groups holding the Employment and Entrepreneurship Certificate, the "enterprise tax absorption policy" shall be indicated on the Employment and Entrepreneurship Certificate; The qualified enterprises shall be issued with the "Certificate of Employment Recognition of Enterprises Absorbing Key Groups".

If there is a change in the number of employees, an application for change shall be made to the human resources and social security department.

The enterprises mentioned in this announcement refer to enterprises and other units that belong to VAT taxpayers or enterprise income tax taxpayers.

(two) the order and amount of tax relief

1. Taxpayers shall calculate the total amount of tax reduction and exemption of their units according to the number of key groups they employ and the actual working months, and deduct the value-added tax, urban maintenance and construction tax, education surcharge and local education surcharge in turn every month within the total amount of tax reduction and exemption. The tax basis of urban maintenance and construction tax, education surcharge and local education surcharge is the value-added tax payable before enjoying this preferential tax policy.

If the actual value-added tax, urban maintenance and construction tax, education surcharge and local education surcharge payable by taxpayers are less than the total amount of tax reduction and exemption, they shall be limited to the actual value-added tax, urban maintenance and construction tax, education surcharge and local education surcharge; If the actual value-added tax, urban maintenance and construction tax, education surcharge and local education surcharge are greater than the total amount of tax reduction and exemption, they shall be limited to the total amount of tax reduction and exemption. At the end of the tax year, if the value-added tax, urban maintenance and construction tax, education surcharge and local education surcharge actually reduced or exempted by the taxpayer are less than the total amount of tax reduction or exemption calculated, the taxpayer will deduct the enterprise income tax with the difference when the enterprise income tax is settled. If the deduction is not completed in the current year, it will not be carried forward to the subsequent annual deduction.

Enjoy preferential policies in the same year, key groups of people working less than 1 year, should be converted to the actual number of months of their total tax reduction and exemption.

Total amount of tax reduction and exemption = ∑ Number of working months of each key group personnel in this enterprise this year ÷12× specific quota standard.

2. In the second year and the following year, the new recruits, the original recruits and their working hours shall be implemented according to the above procedures and measures. Calculate that the maximum period for each key group member to enjoy preferential tax policies shall not exceed 36 months.

(3) Tax relief management

Enterprises that employ key groups to enjoy this preferential treatment shall keep the following materials for future reference:

1. Persons who have been registered as unemployed for more than half a year and enjoy preferential tax policies, registered unemployed persons from zero-employment families and urban low-income families, and the Employment and Entrepreneurship Certificate of college graduates within the graduation year (marked "tax policy for enterprises").

2. The "Certificate of Employment Identification of Enterprises Absorbing Key Groups" issued by the human resources and social security department at or above the county level.

3 "The actual work schedule of key group personnel this year" (see annex).

Three, with the "Employment and Entrepreneurship Certificate" to enjoy the above preferential policies, according to the following provisions to apply for the "Employment and Entrepreneurship Certificate"

(1) Unemployed persons shall register for unemployment in the public employment service institution of their permanent residence and apply for the Employment and Entrepreneurship Certificate. The public employment service agencies shall indicate the registered unemployed persons of zero-employment families and urban low-income families in their Employment and Entrepreneurship Certificates.

(two) during the graduation year, college graduates apply for the Employment and Entrepreneurship Certificate from the public employment service agency with their student ID cards, or entrust the employment guidance center of the university to apply for the Employment and Entrepreneurship Certificate from the public employment service agency; Within the graduation year, college graduates can apply for the Employment and Entrepreneurship Certificate directly from the public employment service agencies with their graduation certificates.

Fourth, the management of preferential tax policies

(a) strict examination and issuance of various documents. No unit or individual may forge, alter, transfer or lease relevant vouchers, and offenders will be punished according to law; For those who lend or transfer the Employment and Entrepreneurship Certificate, the competent human resources and social security department shall take back the Employment and Entrepreneurship Certificate and put it on record; For enterprises and individuals that have obtained tax reduction or exemption by the above means, the competent tax authorities should recover the tax that has been reduced or exempted and deal with it according to law.

(two) "Employment and Entrepreneurship Certificate" adopts real-name registration system, which is limited to the holder’s own use. Entrepreneurs engaged in self-employed, "Employment and Entrepreneurship Certificate" kept by myself; If it is employed by the employer, the certificate shall be kept by the employer during the period of enjoying preferential tax policies. The Employment and Entrepreneurship Certificate is unified by the Ministry of Human Resources and Social Security, and printed by the human resources and social security departments of all provinces, autonomous regions and municipalities directly under the Central Government, as an effective certificate for auditing the employment and unemployment situation of workers and enjoying policies.

(3) The Certificate of Employment Recognition of Enterprises Absorbing Key Groups shall be uniformly printed by the Ministry of Human Resources and Social Security of all provinces, autonomous regions and municipalities directly under the Central Government, and the relevant information shall be provided to the tax authorities by the local human resources and social security departments as required.

(four) at or above the county level human resources and social security, taxation departments and poverty alleviation offices to establish a system of information exchange and investigation of workers’ employment. The Ministry of Human Resources and Social Security has established a nationwide inquiry system for the Employment and Entrepreneurship Certificate, which can be used by human resources and social security, finance and taxation departments at all levels to inquire about the information of the Employment and Entrepreneurship Certificate. The State Council Poverty Alleviation Office has established a unified national poverty alleviation and development information system for poverty alleviation offices at all levels, human resources and social security, finance and taxation departments to inquire about the identity of the poverty-stricken people who have established the card.

(5) If the tax authorities at all levels have doubts about the identity of the poverty-stricken population with the Employment and Entrepreneurship Certificate or the filing card, they may submit it to the human resources and social security department at the same level and the poverty alleviation office for investigation. The human resources and social security department at the same level and the poverty alleviation office shall stipulate a reasonable working time limit according to the specific circumstances, and inform the tax authorities of the investigation results within the time limit.

V. This announcement shall come into force as of January 1, 2019. The Announcement of State Taxation Administration of The People’s Republic of China Ministry of Finance, Ministry of Human Resources and Social Security, Ministry of Education and Ministry of Civil Affairs on the Specific Operational Issues Concerning the Continued Implementation of Tax Policies to Support and Promote Entrepreneurship and Employment of Key Groups (State Taxation Administration of The People’s Republic of China Announcement No.27, 2017) shall be abolished at the same time.

Tank 300 landed for reference, and the owner gave feedback that the fuel consumption per 100 kilometers was 12.93 liters. Are these shortcomings acceptable?

There is no price for youth, and the fuel consumption is 13. The real landing market in April and the real fuel consumption feedback from the owner are shared with you.

Tank 300 drew a picture for young people, outlining a free and chic scene. But in fact, this car is really not suitable for ordinary people to drive. You must have both money and time, otherwise you will be deeply touched after buying it! To put it bluntly, the regret rate of buying is very high, because its purchase threshold is relatively low, and it can be bought at 200,000 yuan, but its use threshold is relatively high, and we don’t talk about financial freedom, but at least you have to be able to afford a car with a consumption of more than 400,000 yuan, which is basically the bottom line. You still have plenty of time to splurge, cross and travel.

If you commute to work at 2: 00 every day and even have to work overtime on weekends, then buying a tank 300 is equivalent to a person who never works out, getting a VIP annual card in the gym, and inviting a fitness instructor. As a result, playing mobile phones in the gym every day is a waste of money!

How much money was wasted? To tell you the market in April, both 2.0T and Conqueror terminals can drop 14,000 yuan, landing at 206,700 yuan and 225,400 yuan respectively. A 2.0T passer-by can descend 15,000 and land at around 235,000.

So what is the real fuel consumption of the tank 300? According to the feedback from the owner, the measured fuel consumption per 100 kilometers by the 2.0T conqueror under comprehensive road conditions is 12.93 liters. According to the current 95th oil price, the fuel cost of this car is basically one yuan per kilometer. If you compare it with this kind of economical city SUV, it’s definitely not comparable. But if you compare with the hard-core off-road vehicle with the same girder and the same 2.0T, the fuel consumption of the tank 300 is even quite close to the people!

However, when you search for Tank 300, you can see that many car owners have bought it in the circle of riders, running in the urban area every day, and they still think that the fuel consumption is high. This kind of car is completely wrong.

So the tank 300 has no shortcomings? I think his biggest shortcoming is that a group of people who can’t afford cross-country can afford real off-road vehicles! Then compare it with the city SUV with the same price, and summarize a lot of problems such as high fuel consumption and poor comfort. If it sells for 100 thousand one day, some people will complain that it has small space and low chassis.

So before you buy the Tank 300, you must think about it. Do you really need an off-road vehicle and do you really have the time and money to go off-road? Now there are many Tanks 300 in the used car market. Although this car is a online celebrity car, it is difficult to sell. The first car owner sold it, mainly because of high fuel consumption and poor second-hand preservation rate, which is also because of this. There is no way, the recognition of niche models is unacceptable.

Scientists make glass "rejuvenate"

  ◎ Intern reporter Li Zhao Yu Dou Peng

  From towering skyscrapers to small and exquisite chronograph watches, glass can be seen everywhere in life.

  Peng Shou, deputy to the National People’s Congress, academician of China Academy of Engineering, chief engineer of China Building Materials Group and president of China Building Materials Research Institute of Glass New Materials, said in an interview that it is necessary to vigorously promote energy conservation and carbon reduction in the glass industry, so that the glass industry in China can "go green".

  In fact, glass should not only "go green", but also be expected to "rejuvenate" — — With the increase of service time, glass will age, which is usually accompanied by the deterioration of physical and mechanical properties. In recent years, more and more attention has been paid to how to "rejuvenate" aging glassy substances and restore their properties.

  At the end of 2022, Jiang Minqiang, a researcher at the Institute of Mechanics, Chinese Academy of Sciences, revealed a new mechanism for the rejuvenation of severely aging metallic glass through research, which deepened the understanding of the rejuvenation of glass structure. Relevant research results were published in Fundamental Research, a multidisciplinary English journal headed and sponsored by the National Natural Science Foundation of China.

  Glass aging: a slow transition from disorder to order

  To make glass "rejuvenate", we must first understand how glass "ages".

  Jiang Minqiang introduced that from a microscopic point of view, glass is an amorphous solid with irregular structure. He gave an example to the reporter: in crystalline solids such as steel, atoms are arranged in an orderly manner like students sitting quietly in a classroom, showing a regular shape. In glass, an amorphous solid with irregular structure, atoms are just like students after class, running around the campus, showing a disorderly arrangement.

  The phenomenon of glass aging, in essence, is the transition of glass from the disordered state when it was initially formed to the orderly state. "Generally speaking, the total energy of matter is higher in disorder state, while in order state, the total energy of matter is lower. As time goes on, glass will gradually change from a high-energy state to a low-energy state. This process is generally called glass aging. " Jiang Minqiang explained that if the aging time is long enough, or the aging is accelerated by heating up, the glass can even be transformed into a solid crystal with a regular structure.

  Glass aging will affect many properties of glass, such as toughness, optical properties and electrical conductivity, which is a phenomenon that people want to delay or even avoid. Therefore, as a process of reversing glass aging, glass rejuvenation has long been widely concerned by researchers.

  "The rejuvenation of glass is the reverse process of glass aging, that is, the glass that makes the atoms relatively orderly after aging slowly returns to the relatively disordered state of atoms." Jiang Minqiang said. In the previous research on glass rejuvenation, the researchers found that the younger glass will release some enthalpy when it is heated to a certain temperature, and the higher the younger the glass is, the more enthalpy will be released during heating. Enthalpy is an important state parameter to characterize the energy of material system. Generally speaking, enthalpy is the energy released by young glass during heating.

  "Our research believes that the above views do not apply to severely aging glass. With the increase of the degree of youthfulness, the enthalpy release of severely aged glass has not changed, or even has no enthalpy release at all. " The research of Jiang Minqiang’s team shows that the previous views on glass aging mechanism are not applicable to severely aging glass, which updates people’s understanding of the mechanism of glass structure rejuvenation.

  "Unintentionally inserted willow": The research result is unexpected.

  "In fact, the breakthrough of this research stems from our research team ‘ Unintentionally inserted willow ’ An attempt. " Jiang Minqiang said that the initial purpose of this experiment was only to prepare experimental samples. "Our team originally prepared samples for another experiment. In order to strengthen the scientific nature of the experiment, it is necessary to eliminate the thermal history of the samples and ensure that their structures are consistent. We anneal the glass samples at low temperature — — Slowly heat the metallic glass to a certain temperature and keep it for enough time, and then cool it to room temperature at a certain speed. " Subsequently, the research team rejuvenated these glasses in a severely aging state through mechanical deformation. The result was unexpected — — "We obviously input energy into the glass through mechanical work. Why don’t these glasses release enthalpy and become younger?" This is contrary to the previous mainstream view.

  This result puzzled the research team. In order to solve the mystery, in addition to measuring enthalpy, the research team also measured the high temperature of glass samples (450K— 750K) and low temperature (1.9K— 100K), and then the atomic vibration information and topological structure information of glass are investigated. "In the course of the experiment, the research team found that although the parameter of enthalpy release before glass transition remains unchanged in some cases, the effective enthalpy change during glass transition and the atomic vibration Bose peak reflected by low temperature specific heat will change accordingly." Jiang Minqiang further explained, "This shows that enthalpy release is not the only physical quantity reflecting the rejuvenation of glass."

  When talking about why the enthalpy release remains unchanged, Jiang Minqiang once again explained with vivid examples: "If we put a ball in ‘ Concave ’ The concave part of the zigzag plane, this ball will naturally remain in place. This stable state is like severely aged glass. And if we put this ‘ Concave ’ The zigzag plane is inclined at some angles. Although the height of the recess, that is, the energy level of the glassy substance, remains almost unchanged, the glass state represented by the ball will become unstable, and then the phenomenon of glass rejuvenation will appear. "

  The results show that, in addition to the previous mainstream point of view, the rejuvenation of glass can be directly reflected in the release of enthalpy, that is, the improvement of energy level, and can also be reflected in the inclination of energy plane, that is, the free volume can be redistributed in space through local structural rearrangement. "This is also the new mechanism of rejuvenation of severely aging glassy substances that we have discovered." Jiang Minqiang said.

  Expand the scene: provide a broad application space

  This study also found that with the glass entering a steady flow state, the above three physical parameters representing the rejuvenation will tend to saturation values, so it was first determined experimentally that the upper limit of the glass structure rejuvenation was a "frozen" steady flow state.

  If water is used as an analogy, glass that forms liquid at high temperature is like water, while glass that solidifies at low temperature is like ice. "The limit of the rejuvenation of the glass structure is that the high-temperature glass liquid is suddenly frozen by rapid cooling, thus forming a similar ‘ Frozen running water ’ The material state. " Jiang Minqiang explained, "In this case, the glass will maintain almost the same material structure as the liquid state under the solid appearance, and its fluidity will reach the limit of current understanding."

  The new mechanism of rejuvenation of glassy materials revealed in this study not only allows us to better understand the related causes and processes of glass aging in physical essence, but also has great potential application space in promoting the batch rejuvenation of aging glass. "The research team is currently communicating with companies engaged in glass production or research and development, trying to find a good combination point to promote technology to the market."

  In addition, Jiang Minqiang also found that the new mechanism revealed in this study is also expected to be applied to the preparation of advanced metal materials.

  "Generally speaking, the strength and toughness of metal materials cannot be both. With the increase of strength, toughness will decrease, and vice versa. " Jiang Minqiang said, "How to overcome this inherent inversion relationship is a problem that must be faced in preparing advanced metal materials with both strength and toughness."

  The total energy level of high-strength metal materials at the microscopic level is generally very low. If energy is input by heating and other methods, it is almost impossible to try to improve the toughness of metal materials by raising the total energy level, which often requires extremely high energy input.

  "If we can use the new mechanism discovered in this study to adjust the energy plane angle of metal materials when the total energy level is low, we can improve the disorder of atoms and enhance the toughness of metal materials while maintaining the macro strength unchanged. Through this method, we can effectively avoid huge energy input and greatly reduce the cost of preparing high-toughness metal materials. " Jiang Minqiang said that his team is constantly trying to make a decisive breakthrough and provide new ideas for solving the irreconcilable contradiction between the strength and toughness of metal materials for a long time.

Second, product competitiveness analysis

With the new energy wave sweeping, the competition in the pure electric medium and large-sized car market is becoming more and more fierce. Among them, Enjoy World S9, which has deep cooperation with Huawei, shows extraordinary strength, and its selling price overlaps with Tengshi Z9 to a certain extent, so they form a competitive relationship. In addition, BMW Brilliance i5 from the traditional luxury brand camp also joined the battle and launched a fierce contest with Tengshi Z9.

From the design point of view, Tengshi Z9 highlights the beauty of smooth lines and is full of movement, which caters to the aesthetics of young consumers. Enjoy the world S9 and BMW Brilliance i5 are both sedate, and the body shape is quite satisfactory.

From the overall price range, Tengshi Z9 has the lowest entry price, while BMW Brilliance i5 is the most expensive top model. In terms of the number of models, Tengshi Z9 offers five models for consumers to choose from, which is quite rich; BMW Brilliance i5 offers four models, while the 2024 Enjoy World S9 only offers two models, leaving little choice.

Specific to the level of vehicle configuration, we selected the models with similar prices as possible. By comparison, Enjoying S9 and BMW Brilliance i5 are both single-motor versions featuring long battery life, while Tengshi Z9 is a three-motor version featuring performance, which is more suitable for young consumers. At the same time, the configuration is also exclusive to the main driver’s knee airbag and AR-HUD augmented reality head-up display, which has a stronger sense of safety and technology. More importantly, Tengshi Z9 has the lowest price, and its cost performance is obviously better than the other two models. In contrast, the overall performance of BMW Brilliance i5 is not as good as the above two models, and there are many missing configurations.

Third, product quality & service trend analysis

As a brand-new car series, will Tengshi Z9 have potential quality problems? In this regard, we will start with the failure problems of Tengshi’s models in the past year, and through the analysis of the failure problems, we will preliminarily predict the development trend of new car quality problems in the future.

By screening the complaint data of Tengshi’s models in the past year, it can be found that the failure problem is mainly concentrated in the aspect of "audio-visual system failure". As Tengshi Z9 is a brand-new model, based on the latest easy tripartite platform, it can be temporarily considered that the probability of the above problems is low, but the specific situation will not be conclusive until it is used for a period of time.

With the continuous development of China’s automobile market, the level of brand pre-sales/after-sales service and the quality of purchase experience have gradually become an important factor affecting consumers’ final purchase. Therefore, based on the big data of car quality network, we will analyze the common service problems of brands in the past year to provide more objective reference for consumers to buy models.

From the point of view of service complaints, "inconsistent with publicity" has become a service problem in which car owners complain more about Tengshi brand. Through further analysis, we can know that this kind of service problem comes from Tengshi N7 and Tengshi D9.

In terms of measuring the after-sales service reputation of new cars, we will analyze the response of enterprises to complaints from car owners, and relatively objectively predict the future after-sales service reputation of new cars. According to the data of Chezhi. com, the response rate of Tengshi brand complaints in the past year is 100%, which shows that manufacturers attach great importance to the demands of car owners.

Four, after-sales service policy and network distribution

In terms of after-sales service policy, Tengshi Z9 has a vehicle warranty of six years or 150,000 kilometers; No fixed number of years/mileage for the first owner of the Third Power Company (the liability exemption clause is subject to the official). In addition, the air suspension is guaranteed for 8 years or 160,000 kilometers (whichever comes first); The first car owner can also enjoy life-long free charging pile and installation service (please consult the local dealer for details).

After the vehicle is purchased, it is bound to involve the daily maintenance of the vehicle. At this time, the number and distribution of brand dealer stores are very important, and even have a certain impact on whether consumers buy the brand model. According to statistics from Chezhi. com, Tengshi currently has 154 dealer stores in China, covering 30 provinces, autonomous regions and municipalities directly under the Central Government, among which Guangdong, Jiangsu and Shandong provinces have a relatively large number of dealers.

Summary:

Tengshi Z9, as a brand-new masterpiece of Tengshi brand, and Tengshi Z9GT form a double flagship. The two not only show the brand’s top technical strength, but also bring unprecedented experience to drivers with excellent luxury quality. At the same time, with strong product strength, it will also lead the new trend of the new energy vehicle market in the future and redefine the standard of luxury electric travel.

Old guns are happy with novices, and they can safely analyze the off-road configuration of tank 300.

  [Original by Aika Automotive Technology Channel]

  Tank 300 has been listed in China for some time. Although there have been several "hot searches" in cross-country circles, consumers’ enthusiasm for it remains undiminished. January was the first complete month after the listing of Tank 300, and its sales volume exceeded 6,000. This performance is even enviable. Some people say that this achievement has taken advantage of the withdrawal of foreign hard-core SUV models from the China market, but in my opinion, friends who play cross-country are often the people who know the most about cars. If there is no excellent product strength, Tank 300 will be "selling itself" again, and even no one will really place an order.

Analysis of off-road configuration of tank 300

  Why does Tank 300 become a fragrant bun in the hearts of off-road fans? Some people say that it has a girder, some say that it has a differential lock, and others say that it is a technological configuration. In my opinion, it is difficult for a single product to form the excellent off-road performance of Tank 300. Only by combining these can the final Tank 300 be formed. So what excellent off-road configurations does it have?

Analysis of off-road configuration of tank 300

  If you ask the older generation of off-road players what a car can be regarded as a hard-core SUV, it will definitely give you three criteria, first, the non-loaded body structure (that is, the beam structure), second, the front and rear integral bridge suspension structure, and finally, the four-wheel drive system with differential lock. Therefore, herdsman, Toyota LC70 (series) and Mercedes-Benz G (old models) will exist in the hearts of off-road players like totems.

Analysis of off-road configuration of tank 300

  With the development of consumer demand, the above three criteria are also changing. For example, the suspension structure has basically evolved into a front double wishbone rear integral bridge, which combines the dual needs of road and off-road, such as Toyota Prado, Land Cruiser and Mercedes-Benz G; The differential lock can also be added later; However, the non-load-bearing body structure remains unchanged, because it can ensure the strength of the body to the greatest extent when it is off-road, and the force is more dispersed when it is dragged.

Analysis of off-road configuration of tank 300

  There is no doubt that the tank 300 has all the three criteria mentioned above. First of all, the non-load-bearing body structure, after Haval H5 and Haval H9, the design of the tank 300 has become more mature. Ensuring a high-rigidity body structure is the main design feature of the tank 300. For this reason, the maximum cross-section of its longitudinal beam has reached 160mmx130mm, and there are 22 reinforcing plates for reinforcement, so there is no problem in meeting the conventional off-road requirements.

  In terms of suspension, the tank 300 uses the integral bridge structure with front double wishbone and rear five links, which is also the structure widely used by other hard-core SUVs, including Mercedes-Benz G, Prado, Land Cruiser and other models, except herdsman/Jimny. Its advantage is that it gives consideration to comfort and off-road performance to the greatest extent, and it also has excellent passing performance while ensuring road handling.

  Tank 300 adopts part-time 4wd system, which has the advantage of simple and reliable structure. Among them, 2H mode is high-speed rear drive, which is suitable for general paved roads. 4H high-speed four-wheel drive and 4L low-speed four-wheel drive are only suitable for unpaved roads because there is no central differential. In the 4L mode, the torque of the tank 300 will be amplified by 2.48 times.
