The 80-year-old woman died after marrying a young man for 25 days (Figure)






The couple, who are in love with their grandmothers, accept everyone’s blessing.


  On September 28th, Delfa Vapes, an 82-year-old Argentine woman, married Renaldo Wavyk, a 24-year-old handsome guy, which once shocked Argentina. After only 25 days of marriage, Delfa suddenly died of a heart attack on the 22nd!


  The sudden death of Delfa, the old bride, caused a sensation in Argentina again. Some people suspect that the groom Renaldo did not hesitate to "murder for money" in order to get the old lady’s inheritance as soon as possible.


  "Grandmother-in-law Love" is 58 years old


  The groom, Renaldo Wavyk, is 24 years old and an unemployed man in Santa Fe, the capital of Santa Fe province in central Argentina. The bride, Delfa Walpes, is 82 years old. She has never been married before, and she has no children or daughters around her. She has already retired for many years.


  According to reports, the love affair between them began nine years ago. After the death of Renaldo’s mother at the age of 15, Delfa, a great friend of Renaldo’s mother, took the initiative to invite the "little boy" to live with him. Who knows, the two had a long relationship.


  On September 28th, the 58-year-old couple held a grand wedding in Santa Fe, which caused a sensation in the whole country. The media in Brazil, Spain, Chile and other countries reported on this shocking wedding.


  At that time, a reporter asked Delfa curiously: "Is this marriage just spiritual?" The 82-year-old bride replied politely, "No, it won’t be just spiritual. There will be many more."


  Only 25 days, the "old bride" died suddenly.


  After the wedding, the couple accepted the invitation of the municipal government of Rio de Janeiro, Brazil, and went to Brazil for their honeymoon. After that, they also plan to travel to Spain and be interviewed by a local TV station to tell their love story. But surprisingly, on October 22nd, shortly after they returned from their honeymoon in Brazil, the old lady Delfa died of a heart attack!


  According to the doctor in charge of her treatment, Delfa’s health began to deteriorate since she got married on September 28th. On October 18th, when she and her husband returned home early, Delfa suffered a heart attack and was sent to the intensive care unit of the local sanatorium in Santa Fe.


  On the morning of the 22nd, she developed complications such as dyspnea and severe pneumonia, and finally died because of ineffective rescue. On the 22nd, a close friend of A Delfa said sadly: "A Delfa said before her death that although she only enjoyed 25 days of marriage in her life, everything in her life has changed wonderfully in the past 25 days."


  The little groom "murdered for money"?


  Since she has no children, Delfa, the old lady, has transferred all her property to the name of "Little Husband". At that time, all kinds of speculations were rampant. It is speculated that the groom Renaldo wanted to get the legacy of the old lady Delfa at an early date, and he did not hesitate to "murder for money".


  Renaldo said that his wife’s unfortunate death made him feel extremely sad: "I can’t accept the fact that I have lost her. I’m not interested in what others say. What I like is only a’ mature woman’. If I only married her for material reasons, then it’s not necessary, because she has already donated all her property to me. There is no one else around her, and the only relative is me. " Yuan hai

Price reduction does not degrade quality! The biggest time in 17 years! Just announced

On November 29th, Yang Yinfen, the helm of Liangpin Shop, sent an internal open letter to all employees:Firing the first shot of "reducing prices without degrading quality"

It clearly puts forward:The largest price adjustment since the establishment of Liangpin Store in 17 years, the average price reduction of more than 300 sharp goods and explosive products was 22%, with the highest drop of 45%, focusing on snacks with cost optimization but no impact on quality and high repurchase rate.

Good shops wield knives inward, which is the same as the problems encountered by many brands that take the quality route at present: the consumption habits are changing with the naked eye: both necessary and necessary. Both the price and the quality are good.

At present, like Box Horse and Anta, good shops have to fight a tough battle. On November 27th, Liangpin Store held the second extraordinary shareholders’ meeting in 2023, and Yang Yinfen, one of the founders of Liangpin Store, was elected as the chairman and general manager of the company. Yang Yinfen took office, the first knife cut down the price at the same time, the internal repeatedly stressed:The price will "go down" and the quality will "not go down".Good shops will never be low-quality and low-price, but adhere to the high-quality route and return to the initial heart of "the quality of conscience, everyone’s shop".

Can a good shop go through the cycle again through drastic reforms?

Return to "everyone’s shop" and be "delicious but not expensive"

On Yang Yinfen’s desk, there are several hot snacks such as nuts and dried bamboo shoots, and different brands of small packages are marked with different prices.

The smell of price war pervades the general manager’s office.

Yang Yinfen’s mind is highly vigilant about the word "price comparison". Price comparison is a price war.

Before the establishment of Liangpin Shop, Yang Yinfen worked as the general manager of Kelon Electric Appliance Branch. The price war broke out at the earliest time in China, and the most tragic one was in the home appliance market, which violated business common sense and made profits thinner than blades.

Yang Yinfen, who rolled out from the price war of home appliances, is more willing to jump out of the price war to see this competition-

"In the era of rational consumption, letting consumers benefit is the optimal solution. The price adjustment of good shops is an adjustment made in response to changes in the external environment and consumer demand. Enterprises must go to the right place alive, reduce prices without degrading quality, and squeeze water from the supply chain and operation and management costs. "

This year, flat replacement products are very hot. The consumer psychology behind the popular word "Pingwei" is that,Consumers want goods with lower prices but the same quality.

Yang Yinfen said that competition makes them see their own problems more clearly, that is, consumers feel that good shops are "expensive". Now, the good shop will return to "everyone’s shop".Let consumers feel that "delicious is not expensive."

Why do good shops make consumers feel expensive?

In August this year, a duck tongue with a price of 528 yuan per kilogram was complained by customers that it was expensive. Later, some media compared 11 duck tongues on the market, and the most expensive one was 798 yuan per kilogram. Compared with the leisure snack brands on the same track, the price of good shops was the lowest, and the duck tongue products on the market were expensive, mainly because the raw materials of finished duck tongues raised the price.

From the consumer report, on September 13, 2023, WeChat tweeted, "Comparison of 11 duck tongues, the most expensive is more than 700 yuan a kilogram, how to choose between price and quality? 》

Nuts, seafood, beef and other categories are all facing this practical problem, because raw materials have raised the overall selling price, giving people this feeling of "expensive".

There are also some perceptions of conduction in business operations: the price tag of good shops and stores has only a single catty price for a long time, without any conversion expression, such as the price tag in Sam will directly convey the price of a small bag, and there are some publicity messages to weaken the impact of the catty price on consumers. In addition, although the price tag of good shops is "Jin price", the cash register system is "kg price", and young consumers "feel bad after seeing the small ticket".

The combination of the above factors makes consumers feel the pain of "price backstab". Behind it, it is also a signal of great changes in consumer psychology-under the economic cycle, consumption power has undergone structural differentiation. In the past, consumers were willing to pay a premium for quality, but now they need goods with a more "quality-price ratio".

Only reduce the price, not lower the quality.

New changes have taken place in the industry.

China’s first discount snack player’s wife appeared in Zhejiang in 2010, but the discount snack shop opened in the past two years, actually stepping on the current economic cycle.

The White Paper on Hard Discount of Snacks in China shows that the discount snack shops sinking into the community are 20%-40% cheaper than traditional retail stores; Average single consumption is 30-50 yuan.

Yang Yinfen said that good shops take the route of high-quality snacks, the cost of raw materials, the input cost of all links in the supply chain, quality control standards, etc., so the price is higher than that of discount snacks; However, if the price is adjusted again, the good shops will not become discount snacks. "The business models are different, the operating costs are different, the brand positioning is different, and the industry ecology is different. Even if it falls to the price of discount snacks, it will not solve our problems."

What is the problem with good shops? "Under the business philosophy of insisting on making high-quality snacks, there is no internal balance between price and quality, and some qualities that consumers don’t care about have caused misunderstandings to consumers. Now, we must optimize these unnecessary costs and return to competitive pricing. "

Back to competitive pricing, but the good shop drew a red line for itself-only price reduction, not quality reduction. Under this red line, optimizing unnecessary costs and cutting off worthless waste become the key.

What is worthless waste?Reflected in the quality control, it is necessary to control the quality that consumers really care about and squeeze out unnecessary costs, taking the quality route, but the products are not so expensive.

Taking nut products as an example, as raw material-based products, in the past, good shops required suppliers to purchase raw materials with specified specifications in the market, and the procurement cost remained high due to high grade.

Now, on the one hand, good shops bring the purchase of bulk nut raw materials into the direct mining system with suppliers, on the other hand, they change the strategy of raw material acquisition, carry out unified market mining, and then classify raw materials. Use different types and grades of raw materials to make different types of products.

Taking macadamia nuts as an example, products with different specifications are used to produce canned nuts, bagged products and comprehensive nuts. Small fruit has the advantage of high kernel opening rate and fullness, so it is used in comprehensive kernel products. By maximizing the use of raw materials, the price of each type of products has dropped by 5-10 yuan.

Another kind of raw material products has also found a way to reduce costs. Dried mango, as one of the explosive products of good shops, has been deeply loved by consumers. Dried mangoes used to be purchased from abroad and transported to China for processing, and there was a waste of raw materials in the middle. This year, good shops have greatly reduced the transportation costs of fresh fruit imports and the waste of finished products by supporting suppliers to set up factories overseas.

In order to achieve "price degradation, quality does not degrade",Yang Yinfen also set up a "Maori red line" internally, and once it is higher than the red line, it will "all fight back".At the same time, the internal cashier system is being tested: quickly identify the gross profit of 1600 items, and the cashier system cannot settle accounts above a certain proportion. In this way, internal teams are forced to reduce intermediate costs and improve management and operational efficiency.

To reduce the price, it is necessary to let consumers feel it.

Since July this year,Good shops began to explore the new pallet structure, and finally realized that the products with popular price and drainage products accounted for 80% of the total.

For this pallet structure, Yang Yinfen elaborated like this-

"The high-quality route goes up, the selection standard is the highest, and it is better to eat, healthier and fresher; Intermediate layer, which sets down the standards that consumers don’t care about in raw materials and auxiliary materials to meet the price requirements of consumers; The most cost-effective product at the bottom is a product that gives consumers thoughts. The key point is to cover young people who agree with the brand and provide them with more and better choices. "

This strategy focuses on differentiated competition. Under the growth flywheel formed by "low gross profit, high turnover and large scale" of discount snacks, homogenization competition is a fatal injury, only to see who is cheaper and who is in a better position. Good shops should build competitive barriers through differentiated innovation, so that consumers can feel that good shops are "delicious and not expensive".

Crispy pancakes sold for 200 million yuan in 2021. The special feature of this product is that 18% fresh potatoes are added to the formula, which makes the biscuit have a unique aroma and taste. This potato is a good product. The shops and suppliers compared the potatoes from all producing areas in China, and after more than 300 experiments, they selected Tengzhou potatoes in Shandong. Tengzhou potato has a high degree of standardized planting, which is convenient for machine peeling and saves costs greatly. The seasoning of crispy pancakes is exclusively provided by a Thai company, which keeps the unique taste.

Because of the scale effect due to the high basket-lifting rate, good shops have long ago hit the gross profit margin of this product to the lowest, and the 300-gram product sold for 12.9 yuan, making it a differentiated "explosive product". At present, the price of 1.32kg products of the same type in Sam is 59.8 yuan, which translates into 22.65 yuan per catty and 21.5 yuan per catty for good shops.

Yang Yinfen said that good shops should make more differentiated "low-priced explosives" like crispy pancakes. Low-price sales is not to engage in absolute low prices, but to make a step on the actual needs of consumers, to give consumers more than expected prices, and to bring more than expected experiences.

In some new products with explosive potential, "scale first, then profit" will enhance the purchasing scale and bargaining power of good shops and provide consumers with more products with high quality and price ratio.

Except for a few areas and special stores, nuts such as macadamia nuts, pine nuts, pistachios and cashews, meat snacks such as pork breast, duck neck and roasted sausage, and explosions with high repurchase rate such as spicy strips, dried beans, bread cakes and melon seeds are now the main force to reduce prices.

Taking nuts as an example, the price reduction of macadamia nuts, pine nuts, almonds and other nut products after price adjustment is up to 40%.

The pork jerky with the first order rate is the key product of this price adjustment. The price of the classic pork jerky is lower than that of Sam, Boxma, 89 yuan, Sam, and 65 yuan, a good shop. A bag of 60g hand-torn preserved meat, membership price of 5.9 yuan, dropped by 40%.

It is not difficult for customers who often visit good shops and stores to find that nearly 30 products of bread and cake products have membership prices: take scattered waffles as an example, the decline is 38%, and rye toast (300g), whole-wheat toast with red dates (300g) and low-fat whole-wheat toast (170g) are all frequently purchased.9.9 yuan……

Now, when we walk into the good shops, there are more explosive snacks that are lower than those in 9.9 yuan, and the prices of these hot snacks such as ganliren, kelp and dried mango are all down. The current membership price of another explosive product, Flandy Strawberry Dried, is only 49.9 yuan/kg, down 40%.

The price of crisp dates (35g), which has sold hundreds of millions of bags and been "stamped and verified" by numerous foodies, was also transferred from 7.9 yuan to 5.9 yuan for one bag.

Yang Yinfen said that the price reduction is below 20%, and consumers don’t feel much. "Everyone thinks you are expensive, so you must change, stay the same, and you will die."

The bottom line of price reduction comes from the improvement of supply chain efficiency

"This is a major business change for the company." Yang Yinfen said that good shops must ensure that they are still at the poker table in the future.

According to the consulting data of Ai Media, from 2010 to 2022, the size of the snack market in China will increase from 410 billion yuan to 11,654 trillion yuan, and it will maintain a steady growth trend in the next few years.

The plates in China snack market are expanding, but the channel reform is fierce, and the market share of good shops is shrinking. According to the data of Euromonitor and China Merchants Securities, in 2022, the market share of good shops is 1.6%, and the number one Mars is only 3.5%. The snack market is very scattered, and there is no scale effect.

In such a short time, there are so many discount snack shops in the market, and the attack speed is so fast, just like Ali and JD.COM looked down on Pinduoduo in those days. Now, the market value of Pinduoduo, which started from the low-end market, is four times that of JD.COM. Will such "low-end subversion" happen in the snack circle?

The exterior is changing vigorously. Where should the good shops go in the future?

Yang Yinfen believes that there is a certain capital bubble in the snack industry. There are 18 snack brands in a county. Is it that the enthusiasm of China consumers to eat snacks has suddenly increased by four or five times? The snack industry earns hard money, noThe low price supported by profit cannot be copied and sustained, and then there will be a elimination period and a cooling-off period.

Good shops have their own way to go.

According to the third quarterly report of Liangpin Shop, 291 new stores were opened in the third quarter, and the sales in South China, Southwest China, North China and Northwest China all achieved double-digit growth, and the sales of direct retail business increased by 35.33% year-on-year.

By opening a store to seize the blank market, expand the scale, gain sales growth, further improve efficiency and reduce costs. Yang Yinfen said that under the current competitive situation, good shops give priority to revenue growth, reduce profit requirements, and benefit consumers and cover a wider range of people by integrating supply chain resources.

Yang Yinfen frankly said that this competition made him see that there is still room for improvement in supply chain management of good shops, and good products need to be upgraded again.

All recessions are essentially replaced by lower-cost and more efficient models. Yang Yinfen, who rolled out from the price war, has a clear understanding of this. A good shop that is about to enter the age of 18 needs a new supply chain revolution to complete the "adult ceremony".

"We are not afraid of being caught, and what can’t kill us will make us stronger." Yang Yinfen said.

To be friends with consumers, this "supply chain revolution" must be fought down.

At present, it is not only good shops that are making large-scale price adjustments to cope with this change in the retail industry.

During this period, the box horse fresh played the "moving mountain price", which set off the prelude of the box horse reform. The low price of "moving mountains" mainly comes from the reform of supply chain.

The low price of discount snacks comes from low gross profit, high turnover and large-scale opening of stores. Through opening and joining, it can expand rapidly, make large-scale sales and form an absolute right to speak on the price of suppliers.

Yang Yinfen said that good shops and discount snacks are two completely different species. Discounting snacks is a channel logic, not a supply chain, not producing snacks, but a supplier. Good shop is channel+product logic, which has established a long industrial chain that goes straight back to the origin of raw materials. It is determined by the self-operated model that packaging should be designed, research and development should be done and product quality standards should be made.

The two have formed different price logic, and the methods of squeezing water from the supply chain are also different.

The way for a good shop is to squeeze water from lean management, save costs, and get rid of all wastes that customers think are worthless, so that every partner in the industrial chain can become a participant, contributor and beneficiary of reducing costs and increasing efficiency.

Back to the key question, why can good shops concentrate on reducing prices in a short time and directly benefit consumers?

On the surface, this is a price war, but in essence, it is a supply chain revolution. The key to winning is who has the ability to fight this supply chain revolution, and who has the ability to fight can truly reduce prices without degrading quality.

Squeezing water from the supply chain is a game of discourse power, cost control, product quality, production efficiency and commercial efficiency. To obtain a reasonable and competitive cost and have sufficient control over the supply chain, the core is to get the advantages of the whole chain, not just one port.

There are 330 suppliers of good shops. To control such a huge supply chain network and achieve a breakthrough requires long-term accumulation and upstream and downstream capabilities of the entire supply chain.

Yang Yinfen told suppliers that this industry is undergoing profound changes, and all walks of life are involved. If you don’t, you will be swept away by others. But this kind of roll is definitely not the ultimate squeeze on suppliers. "Suppliers are insecure and people don’t play with you." Yang Yinfen said.

This revolution began as early as 2020, and the strategic goal of the good shop this year was to form a breakthrough in cost audit. Help suppliers improve their lean management capabilities through 12 dimensions, such as job standardization, automation and continuous flow operation. In that year, good shops visited nearly 30 suppliers, and the procurement cost of suppliers decreased by 19.13 million. In 2021, the cost was reduced by 23 million.

The data accumulated in this large-scale audit provides an important reference for cost pricing, and the good shop has established a cost database and a set of digital management system for managing supply chain costs.

Still in 2020, the good shop promoted the factory to send the "seven-day fresh" model directly, and it took only seven days for nuts to be placed from order to harvest every day, which greatly improved the freshness. Good shops broadcast live in the factory, so that consumers can see the improvement of speed and efficiency with their own eyes. The conversion rate has increased by 102% and the repurchase rate has increased by 89%. The factory direct delivery mode saves 6 million yuan in logistics cost one year. Now, this mode is fully promoted in the supply chain system of good shops. And the premise of promotion lies in:

All factories that produce "7-day fresh" products need to meet a strict condition-on this single product of comprehensive nuts, the qualified rate of arrival in 2019 can reach 99.5%, that is, no more than 5 defective products per 1,000 pieces. In addition, the good shop also reached an agreement with the factory-the factory authorized to open the monitoring of the production process to the quality control personnel of the good shop and implement cloud monitoring for every link.

The explosion of over 100 million pieces of fragrant iron eggs dropped by 23% this time, and the space for price reduction was dug out from lean management. Under the guidance of the good shop, the supplier saved 1.05 million yuan a year by optimizing the production equipment, changing the method of peeling eggs, upgrading the packaging technology, and introducing color sorters instead of manual selection of "flower eggs". At present, the price per catty of this product is 39.9 yuan, and 92g of the box of Ma Xiang halogen iron eggs in bags is 9.9 yuan, which translates into a price per catty of 53.8 yuan.

The logistics carton of the New Year Festival has been reduced by 18.4% in 2022. Can it be squeezed further this year? The good shop will disassemble the packaging box, dig it one by one and adjust it one by one. It is estimated that the cost will be reduced by 8.62 million yuan in 2024.

In the end, these little costs are reflected in the price reduction of products and the benefits are given to consumers.

Where is the difficulty in the price reduction reform of good shops?

"It is necessary to further build consumers’ quality mentality for good shops; And be alert to the inertia of internal system operation. " Yang Yinfen said:"Snacks are popular products. What we do is the business of people who love life and enjoy the quality of life. The key for us to be friends with consumers is to ensure quality, and never make low-quality and low-priced products. Always remember that our initial intention is to be "the quality of conscience, everyone’s shop."

Can you beat Highlander? 2024 Mazda CX-70 real car debut, is expected to 300,000

In the automotive market, the launch of new cars always causes a lot of buzz. Not long ago, the 2024 CX-70 was unveiled, and it was heard that its price is expected to start from 300,000. As soon as the news came out, it immediately attracted a lot of interest from fans and consumers, and one of the most interesting questions was, can this car be compared?

Hey, in recent years, the performance in our country has been a bit mediocre. In a lot of joint venture brands, it has long been no longer the leader, and even a little overshadowed. But with the emergence of a new generation of CX-70, Mazda seems to be challenging this situation.

Let’s talk about the exterior design of this car first. Mazda has always been famous for its unique design style, and this CX-70 is no exception. The exterior looks beautiful, full of movement and sporty atmosphere, especially those young people will definitely be attracted. In contrast, although it is also a medium-sized model, its design is a bit old-fashioned and may be a bit outdated.

Then, product strength is also the key to winning. It is said that the CX-70’s interior workmanship and configuration level are quite good, and there may be a large displacement, providing more powerful power. This is definitely a big advantage in the competition.

Finally, let’s talk about the price. I heard that the starting price of this Mazda CX-70 is about 300,000, which is not high compared to Highlander. Coupled with its appearance, interior and power advantages, this price looks quite attractive.

Overall, the appearance of the 2024 Mazda CX-70 provides consumers with a new choice. Although it is not easy to completely beat the mainstream medium-sized like Highlander, Mazda seems to be ready. Its unique design, strong product force and reasonable price positioning all make people look forward to its future. As for whether it can really beat the Highlander? Maybe only time will tell.

SUV sales in March: Model Y is far ahead, and Mercedes-Benz GLC is selling crazy.

Affected by the price war, the domestic auto market showed strong vitality in March, with retail sales reaching 1.69 million vehicles, up by 6.2% and 53.1% respectively from the same month and the previous month, among which SUV once again took the lead, with sales of 801,070 vehicles, accounting for 47.21% of the market share, up by 10.76% and 47.63% respectively from the same month and the previous month, which shows that the SUV market still maintains a strong growth momentum.

Specifically, the best-selling SUV model in March was 47,917 vehicles, and it was also the only model with a monthly sales of 40,000, leading the second place in Song Pro DM-I (27,446 vehicles). However, although the sales volume of Model Y is good, it is still down by 12.78% compared with the same period of last year, which shows that it is still influenced by its own brands. After all,,, and so on have joined the price war, and the cost performance is very high. However, considering that Model Y has risen against the trend in the price war, it can still have such sales volume, and its competitiveness can be seen.

Undoubtedly, the biggest winner in the SUV market is that three models have entered the top five and four models have entered the top fifteen, and there are both plug-in models such as Song PLUS DM-i, Song Pro DM-i and Tang DM-i, as well as pure electric models. Except Tang DM-i, all four models are frequent visitors on the list, all of which have certain influence. Coupled with the recent launch of the glory version, the price has been lowered and the configuration has increased, and the sales volume is natural.

BYD Song PLUS DM-i is the sales champion of its own brand new energy SUV, and it is also the sales champion of its own brand fuel SUV. The new car was rejuvenated earlier, and the whole system comes standard with 8AT transmission. The level of intelligence is also the best among traditional car companies, and with greater concessions, the sales performance is still strong, but it is not weak next door, and it will be replaced soon, and it will still face greater pressure in the future.

In March, the sales volume declined both in the same period and month-on-month, and it was still the first new force and the first SUV. After all, there have been many heavy new cars recently, such as the new 001, the new model, etc. The old L7 is also clearing its inventory at a reduced price, which has somewhat affected the M7. However, with the help of HarmonyOS car and ADS 2.0, there has been a big discount recently. The price of the rear-drive version has been reduced by 20,000, and the price of the rear-drive intelligent driving version has been reduced by 10,000, which still keeps selling well. It is worth mentioning that the M7 will be redesigned next, the product strength will be improved, and the old models will be reduced in price to clear the inventory. However, they will also be listed. If they are both 250,000-class SUVs, who would you choose?

Surprisingly, the joint venture fuel SUV sold 19,000 vehicles, ranking fifth in the SUV sales list. On the one hand, as a first-line luxury brand, it has a wide popularity and reputation in the market, and naturally has natural advantages in sales. On the other hand, Mercedes-Benz GLC has recently given a big discount, with a price reduction of about 50,000, and more than 370,000 entry models can be bought. Although the price is exchanged for the quantity, the comprehensive strength of GLC is still worthy of recognition. After all, the discount at the same level is about 100,000, which only ranks 15th.

Look at other models on the list, Haval H6, Geely and, all of which are frequent visitors on the list, with more than 10,000 vehicles in March. All four models have good product strength and user base, and they have also received large discounts recently. For example, Feng Landa bought a joint venture compact SUV in the early 110,000 s, which is still very attractive.

Overall, independent brands still occupy an absolute advantage in the SUV market, and the proportion has increased compared with last month. It can be seen that the R&D and production capacity of independent brands in the SUV market has been continuously improved, which can meet the diversified needs of consumers. At the same time, new energy vehicles and fuel vehicles account for half of the list, showing the rapid development of the new energy vehicle market and the increasing acceptance of new energy vehicles by consumers.

In addition, under the price war, the SUV market in March showed the characteristics of diversification and fierce competition. Although consumers pay attention to many factors such as product performance, appearance, configuration and brand reputation, price is still an important influencing factor, and most of the listed models have great discounts recently, but "exchanging price for quantity" is not a long-term solution. The focus should be on brand reputation and product strength to better meet consumers’ demand for car purchase and cope with market changes.

Zhiji Automobile Beijing Fifth Ring Expressway Elevated NOA is fully opened, and it is expected to cover the whole country by the end of this year.

On September 15 th, Zhiji Automobile announced today the new progress in the layout of IM AD high-speed elevated NOA (IT note: automatic assisted navigation and driving), which has covered 12 provinces and 26 cities nationwide so far.

Zhiji said that while accelerating the expansion of the high-speed elevated NOA map, IM AD is conducting internal testing of urban NOA, and will officially open the public beta in October. In 2024, IM AD will realize "commuter mode and all cities will open together";

According to the previous official introduction, Zhiji IM AD is the only self-developed manufacturer in the industry that is compatible with Xavier and Orin dual intelligent driving computing platforms, and has efficient algorithm development capabilities. Based on the statistics of the frequency of road collision accidents in China, IM AD is 0.6 times per million kilometers, and human beings drive 1.9 times per million kilometers. IM AD is 3.2 times safer than human driving. According to the frequency of safety misoperation, IM AD is less than once per million kilometers, which is five times the industry level.

Golf is really not expensive. The public plays ball and uses these clever tricks to break the aristocratic model.

  "Green Club" is an exclusive original brand column launched by Tencent Golf. Explain the star players, schedule etiquette, schedule rules and other information of golf in detail. The green is for the best, who is in charge of the ups and downs.

  Today, people still seem to have great misunderstandings about golf. When it comes to golf, most people’s first impression is: expensive. Expensive has two explanations, one is aristocratic movement, and the other is expensive. As everyone knows, golf has gradually become a popular sport, because its cost is really not as expensive as people think.

  In fact, in recent years, the cost of playing an 18-hole golf in first-tier cities in China is 1,800 yuan, the cheapest is 470 yuan, and the public price is 8,900 yuan. An 18-hole golf course takes almost four and a half hours, and the average hourly consumption is about 200 yuan. Playing tennis, badminton, even basketball and football is almost the same consumption level. In this way, do you still think playing golf is expensive? And this is the consumption level of first-tier cities. If you know the prices in other cities, I’m afraid you will shout "cheap".

  Therefore, golf has become a popular sport, which is really not just an expression. In recent years, more and more people play golf, and the price factor is only one aspect. More importantly, golf is the best exercise to keep healthy. The following will popularize the coup that can save money to play ball from many aspects.

  A coup to crack the high threshold of equipment

  In the United States, where golf is prevalent, it is often seen that children under the age of 10 play 18 holes with their bags on their backs. In the eyes of those children and parents, golf is an ordinary sport, and most people can participate in it. A game costs only 20-30 US dollars (about 135-200 yuan RMB).

  Back in China, it is a world of ice and fire, and golf has been labeled as an "aristocratic sport". Is the price of playing golf not close to the people, or are people misreading the sport?

  Comparing golf with other sports-tennis, badminton, swimming, skiing and equestrian, you will find that the cost of golf clubs and balls is indeed higher than other sports. Tennis, badminton and swimming equipment have the lowest price, which can be done within 200 yuan; If only helmets and gloves (excluding horses themselves) are counted in equestrian, the price is around 300 yuan; Although the price of skiing equipment is higher than that of golf equipment, most ski resorts provide free rental services for skis and ski suits. Therefore, the equipment threshold for playing golf is indeed higher than that for general sports.

  But in the face of the high threshold of equipment, can we only flinch? The answer is not like this!

  With the improvement of their own skills, many golfers will change their clubs regularly, so how to deal with the old ones? If you don’t have friends to send, it will take up space at home, and it will be a pity to throw it away. In fact, there is also a big market for second-hand clubs. You can try to sell them on some second-hand resale platforms or special club second-hand websites. Of course, golfers in the beginner stage can also choose to buy second-hand clubs.

  The price of golf course is not completely high and cold.

  If the equipment "sets" the threshold for golf, is its venue price higher than other sports?

  Most standard golf courses are membership courses, and members need to pay expensive membership fees to play, but these courses also accept individual bookings. Due to the different prices of high-end and low-end courses, the price of playing golf in the courses that receive individual guests ranges from 310 yuan to 1920 yuan, and the price per person per hour ranges from 77.5 yuan to 480 yuan (calculated according to four hours per game).

  The prices of indoor and outdoor venues are quite different, and the prices of indoor venues are also very different due to different conditions. The hourly price of tennis venues ranges from 50 to 580 yuan, and the consumption price per person per hour ranges from 25 to 290 yuan (calculated by two-person AA system). The public has misunderstood golf courses. Many golf courses are not "high and cold" as everyone thinks, and their prices are close to the people, while the fees of other sports venues are not low. Some participants in tennis and equestrian have the financial strength to join golf.

  There are some tips in this respect. When you want to play on a golf course, you may wish to ask your golfers if they have an anonymous membership card, or you can ask members to help you book a court and use the guest price. In addition, there are a lot of booking software and playing packages on the Internet now, so pay more attention to playing more games with the same money.

  Tee time on weekdays and mornings is low in many courses, so you may wish to choose this time if it is convenient. Not only is the state of the stadium better, but you can bid farewell to the "traffic jam" and you will have a sense of carefree monopolizing the stadium. Now there is a 9-hole mini golf course that is becoming more and more popular, mainly because of its reasonable price and short time consumption. Many times you don’t have four hours, but two hours sounds much easier.

  A year’s fee is less than one night’s nightclub consumption?

  At one time, it was roughly calculated that the cost of playing golf a year could not even cover the consumption of a nightclub for one night. How much does it cost to play golf for a year? I believe everyone gives different answers. Let’s figure out how much money to spend at least a year from the most economical aspect …

  Suppose a person: he plays 30 games a year, buys clothes but doesn’t change his pole, and drives himself every time. How much does he need to spend a year? 

  Equipment cost (10000)= clothing (5000)+ ball (1000)+ driving range (4000) 

  Playing fee (19500)= travelling fee (150)+ green fee (500)× number of games (30 games) 

  Total cost (29500)= equipment cost (10000)+ playing fee (19500)

  The above total cost is a span of one year, and in nightclubs in first-tier cities in China, the consumption for one night is sometimes this figure. And the two forms of entertainment are not at the same level for people’s physical and mental health. Can you still say that it is really expensive?

  The above expenses are a general situation, and this article also has some tips to save money. For example, bring your own drinks and snacks. Many golfers love to drink a sports drink and eat some energy bars and chocolates at the end of the game. However, these things are often sold very expensive in the stadium. You may think that it is nothing to listen to a coke for 25 yuan, but it is also a big expense after a long time. After all, the supermarket only sells 3 yuan.

  Straight flush, buy a ball catcher. As the "king of a bag of balls", there are always a few balls left in the water obstacle area every game. Next time you spend 50 yuan on a ball catcher, you can earn back the cost by picking up two balls. Besides, catching the ball is very fulfilling.

  You can also use second-hand balls at ordinary times. A brand-new box of good balls will certainly improve the playing experience, but if you are still a "tricycle", it will be a bit wasteful to throw a box of balls down the 18th hole. There are a large number of second-hand balls sold in the network and shops, which vary according to the color and brand. You can consider buying some, so it won’t be too painful.

  Secondly, walk instead of cart. There are also many stadiums in China that can choose not to use carts. It is also a very good choice to walk and chat with friends while enjoying the scenery of the stadium. This can not only save a sum of money, but also get close to nature, breathe fresh air and exercise. Isn’t that the charm of golf?

  Golf, expensive or not, is more of a psychological "expensive" for Chinese people. If you convert the physical and mental health brought by this sport into value, you will find that such "expensive" is really cheap.

The universe we live in is just a holographic projection?

#00958C
In the past few decades, with many of us spending a lot of time online, the real world seems to have become wider. However, in one field of theoretical physics, the situation seems to be developing in the opposite direction. In the past twenty years (although this article was written in 2009, it is still worth reading), string theorists have been discussing the view that the time and space we live in, including ourselves, may be just an illusion.Holograms produced by "some reality". And this reality lacks a key feature of the world we perceive: the third dimension. Professor Juan Maldacena of Princeton Institute of Advanced Studies has played a decisive role in the development of the idea of holographic principle. In the 1990s, Marda Sina proposed the first implementation.Cosmological model of holographic principle. Recently, he was interviewed by the author during his visit to Cambridge.
The holographic principle originated from one of the biggest scientific problems in the 20th century:There is incompatibility between general relativity and quantum mechanics..
At the beginning of the twentieth century, Einstein discovered thatTime and space are inseparable.He called the structure formed by the two space-time. His general theory of relativity points out that space-time itself willDistorted by a massive objectAnd gravity is the result of this distortion. It’s like putting a billiard ball on a trampoline, which will create a depression and make the nearby marbles roll into it; Similarly, massive objects (such as planets) will bend space-time and attract nearby objects by their gravity. According to Einstein, gravity is not something that propagates through space, but is caused by the geometric structure of space-time itself.
general theory of relativityThe main description isPlanets and galaxiesThe world, and quantum mechanics mainly focuses on the subatomic scale, that is, the basic particles that make up matter. At this scale, the mass is so small that gravity can be ignored. Quantum field theory is a quantum mechanical description of particle physics, which holds that elementary particles transmit force through messenger particles called gauge bosons:One elementary particle transmits force to another particle by sending some gauge bosons..
Figure 1. Huge objects distort space-time.
In the development of the 20th century, electromagnetic force, weak nuclear force and strong nuclear force are the four basic forces.Messenger particleAre all in the experimentBe observedYes. In order to maintain theoretical consistency, Einstein’s theory should also be able to be rewritten with similar messenger particles. Physicists willGravitational messengerParticles are calledgion(graviton), but we haven’t found its trace yet. Even more frustrating, tryingUsing quantum field theory to describe graviton meetinglead toinsignificance/meaninglessThe answer. Marda Sinar said: "Simply quantizing gravity is not feasible, which will lead to mathematical inconsistency. We need something new. "
So far, a much-anticipated new quantum gravity theory has not been discovered. A strong competitor isString theory, or "string theory family"-because string theory is actually a set of logically self-consistent.A collection of theories. The core point of string theory is to put the basicParticles are regarded as tiny vibrating strings.This provides a way for us to bypass the mathematical problems in simple quantum gravity. As a mathematical theory that has attracted many theorists with its beauty, the disadvantage of string theory is that it has not been given.A complete description of the worldMany physical quantities cannot be described yet. In addition, string theory has not been verified by experiments, and it can’t be verified in fact. However, it is string theory that provides Marda Sinar with a clue to solve the mystery of quantum gravity: regard gravity as an illusion produced by quantum holograms.
Figure 2. Quantum mechanics describes the subatomic world well.
The contradiction between general relativity and quantum mechanics will not bother most practical applications. What physicists usually study isLarge-scale worldHere it is.The quantum effect is not obviousOr a small-scale world, where particles are lighter and gravity has less influence. However, in a special case, the conflict between the two theories becomes particularly obvious: when a large amount of mass is concentrated in a small area of space, a black hole will be formed.. The gravity produced by a black hole is so strong that even light cannot escape.Therefore, when studying black holes, we can’t ignore the influence of gravity. At the same time,The small scale of black holes also means the existence of quantum effects.. Therefore, in order to explain the phenomena in black holes, we really need a unified theory of quantum gravity.
Black holes are the original holographic principle.Theoretical sources. They have a boundary that cannot be returned, which is called the event horizon. Once you cross this boundary, you will be sucked into the black hole and never escape. When you fall into a black hole, a lot of information will disappear with you. This information includes not only your DNA and one or two best ideas, but also countless combinations of blood cells in your veins and all the confused thoughts in your mind. However, in the world of black holes, things look much simpler. Classical physics assumes that nothing can escape from a black hole, and thinks that a black hole can be used only.Three messagesTo fully describe:Its qualityelectric chargeandspin velocity. Therefore, when you fall into a black hole, all the information needed to describe you will be sucked into these three parameters of the black hole-your fall makes the universe a little simpler.
Figure 3. A simulated black hole with the background of the Milky Way.
This reduction in complexity usually worries physicists because it violates one of the most basic laws of physics:second law of thermodynamics. The second law of thermodynamics shows that things will never get simpler. The total amount of information needed to describe a system is measured by a physical quantity called entropy. In classical physics, entropy is defined for thermodynamic systems, such as melting ice under the sun. Classical entropy measures the degree of heat (or energy) dissipation in a system.
However, energy is related to excited atoms (in ice, water molecules are arranged in a fixed lattice in order, while in liquid water, they move around), so entropy is also a standard to measure the disorder of the system. The disorder degree of the system is related to information: the periodic arrangement of water molecules in ice crystals can be described in one sentence, but for liquid water, you need to provide the exact position of each molecule, which involves a lot of information. Therefore, entropy is related to both thermodynamics and information.
The second law of thermodynamics shows that,Entropy will never decrease.. Under thermodynamic conditions, this means that the system will strive to reach the equilibrium state of complete energy dissipation. In the context of information, this means that things will not automatically become simpler. From the classical point of view, a black hole is not a hot object, and it is very simple to describe, so there should be no entropy. When you fall into a black hole, your positive entropy will become the zero entropy of the black hole, whichViolation of the second law of thermodynamics.
When this potential problem is noticed, some physicists can only accept the fact that the second law of thermodynamics may not be as basic as we thought. However, one physicist, Jacob Bekenstein, was unwilling to give up easily. In 1972, Beckenstein discovered the relationship between entropy and the properties of black holes discovered by Stephen Hawking. Hawking has been thinking about the horizon of a black hole. The event horizon wraps a certain space volume like an egg shell-it is a surface, and you can measure its area. Hawking has proved that,The horizon will never shrink.No matter what you do or put into a black hole, the area of the horizon will only increase, just like entropy.
Figure 4. The second law of thermodynamics paves the way for the holographic principle.
This analogy with thermodynamics was initially thought to be purely coincidental, but Beckenstein put forward a controversial explanation: "Beckenstein thinks you can putThe area of event horizon is regarded as a kind of entropy., "Marda Sina explained. "The idea was not clear at first, but when Hawking discovered that black holes couldquantity of radiant energy(now known as Hawking radiation), this idea became more clear. In other words, black holes are hot objects, so they must have entropy. "By combining Beckenstein’s original idea with Hawking radiation, we can calculate that the entropy of a black hole is indeed equal to the area of a black hole measured in a certain length scale-Planck unit. Because Planck unit is very small, soEntropy of black holeIs a considerable value. Although the black hole occupies the three-dimensional volume of space, its information content seems to be a feature of its two-dimensional event horizon.
You may think that black holes are very strange things, but physicists Gairal Us’ t Hofter and Leonard Susskind went one step further, and they considered those in ordinary space areas.information content. Whether it is the pages of books, neurons in the brain or photons transmitted through optical fibers on the Internet, information exists in physical form. This physical form involves energy. Since energy is equal to mass (recall Einstein’s E = MC), compressing information into a limited area of space is equivalent to compressing mass into it. If you try to put too muchQuality/information is compressed into it.You will get a black hole, so the information content in the limited space of non-black hole is limited. Hofter and Susskind calculated this limit, and found that it is measured in the same way as a black hole, which is measured by the surface area of the regional boundary.
Marda Sina said: "This may sound very simple and naive, but in all our other descriptions of the world, variables increase with the increase of volume. For example, if we want to describe the electromagnetic field in a space, we will divide the volume into many parts and describe the electromagnetic field of each part. " If you double the size of the area, you should also double the number of partitions, so the information required for your description should also be doubled. According to this intuitive idea, information should increase with the increase of volume, not with the increase of area as described by holographic principle. If the holographic principle is correct, then the three-dimensional method of our physics is wrong. We should be able to use a simpler version of physics, one that depends on area rather than volume. This leads to a puzzling question, that is, whether the third dimension really exists, or whether it is just an illusion, just like a three-dimensional image created in a hologram.
So far, no one has found an accurate formula to describe the two-dimensional version of physics in our three-dimensional world. However, in 1995, Susskind redefined string theory centering on holographic principle. Then in 1997, Juan Marda Sinar, who was only 29 years old, put forward a concrete description of the first holographic universe in history.
Marda Sina’s universe is not completely in line with the universe we actually live in: it is amodelA "toy" universe has its own complete set of physical rules. Because all the physical phenomena that occur in it can be defined by only.Physical theory on the boundaryTo describe, so this toy universe is aholograph. More importantly, in this universe, the problem between gravity and quantum mechanics has been completely solved: the theory defined on the boundary is pure quantum, which does not contain gravity, but the creatures living in it can still feel gravity. In this universe,Gravity is only part of the hologram illusion..
In order to understand the toy world of Marda Sina, we need to understand the world of map making first. In order to show the sphere on a flat piece of paper, we need to cut the sphere and flatten it, which will inevitably introduce some distortion. In the traditional Mercator projection of the earth, this distortion is the most serious near the poles. When you look at the map, Greenland looks as big as Africa, but in fact it is more than 14 times smaller. Besides, if you project the shortest path from London to Sydney on the map, you will get a curve instead of a straight line. On a map like this,A straight line does not correspond to the shortest path..
Figure 5. Mercator projection of the earth. The red disks actually have the same area, but their different sizes on the map illustrate the distortion of the map.
MC escher’s famous woodcut "Circle Limit III" shows a two-dimensional map of Marda’s Sina universe. Similar to Mercator projection, there are some distortions here. In escher’s map, the shortest route between two points is not a straight line connecting them, but an arc intersecting with the boundary circle of a disk at right angles.
Fig. 6. The Circle Limit III by MC escher. The shortest path is shown in white.
If you use this new metric to measure the size of fish, you will find that, contrary to their appearance, they don’t get smaller and smaller as they approach the boundary circle, but they are actually equal in size. Just as travelers walking on the surface of the earth will not realize the distortion shown by Mercator projection, people living in this so-called hyperboloid world will never notice any distortion in the size of fish. More importantly, in order to reach the boundary circle, the hyperbola must pass through an infinite number of copies of fish of the same size. In other words, it will have to span an infinite distance. For hyperbola, the boundary circle is infinitely far away.
Unlike a hyperboloid map, a "real" hyperboloid can hardly be drawn because it is severely distorted. Hyperbolic surfaces have what mathematicians call negative curvature. The small area of this "plane" looks like a saddle: along one direction, they look like the peak of a ridge; In the other direction, they look like the bottom of the valley.
For external observers like us, this strange two-dimensional world has an interesting feature: although according to new metrics, theirThe scope is infinite.But we can see their boundaries-this is exactly what we need to apply the holographic principle, which describes the interior of the space area according to the boundaries. In Marda Siner’s model of the universe, he used the three-dimensional simulation of hyperboloid plus the fourth dimension of time to form a model called anti-sitter space, which was named after the Dutch physicist William de Sitter.
Anti-de Sitter space is completely different from the world we actually live in.Where time and space are distorted in strange ways, but this does not prevent us from creating a set of physical rules for it. What you need is something.basic concept, such as elementary particles and forces, and the mathematical laws describing their interaction. Marda Sinar used a version of string theory to describe the physical phenomena in his model universe. As you remember, string theory includes quantum mechanics and gravity, so creatures living in Marda Sinar’s model universe will feel gravity in a way similar to ours.
Figure 7. A holographic universe
Marda Sinar’s key discovery is that the string theory describing the interior of the universe leaves a "shadow" on the boundary of the universe: you can define a quantum field theory on the boundary, so that every elementary particle in the interior has a corresponding particle on the boundary, and every interaction between elementary particles in the interior exactly corresponds to the interaction between boundary particles. Now you can completely describe it with the theory of boundary, for example, the action of throwing an apple inside. This means that you can even completely ignore the inner world without losing any information-this world is a real hologram.
From the point of view of quantum gravity, the key point is that the boundary theory is a quantum theory of particle physics that we are very familiar with, which is very similar to the theory used to describe the process of subatomic particles in nature. They only involve small scales, so they don’t include gravity. However, the quantum theory on this boundary can completely describe the mysterious quantum gravity theory in the internal world. This is the first time that we can completely describe a quantum spacetime.
So far, Marda Sina’s modelIt’s just a model. We don’t know whether the universe we live in is a hologram, and we still don’t have a consistent quantized description of gravity applicable to our world. The assumption of negative curvature in Marda’s Sinar model is very important, but our universe shows a slight positive curvature in the observation results. Marda Sina said: "We don’t know if there is a similar description in the case of positive curvature. People are exploring various ideas, but we don’t have a complete answer yet. "
But if it turns out that the holographic principle really applies to the world we live in, what will it mean? Does this mean that we and time and space are just an illusion? "Yes, you can say that we are an illusion or an emerging phenomenon," said Marda Sina. If we live in such a universe, then we are actually an approximate description in a sense. But this is not a new concept in physics. Take the lake as an example. It looks like a well-defined surface on which insects can walk. But if you look at it with a powerful enough microscope, you will find that there are molecules moving around and there is no clearly defined surface. For time and space, the situation may be similar. It is not clearly defined in absolute sense, but we are too big to realize it. Like insects on the lake, our eyes for observing the world are too rough to reveal the true nature of time and space. Ignorance is bliss. Although it is endless fun to discuss the philosophical aspects of things, from the perspective of daily practice, weWhether you live in a hologram or not may not matter.. "
However, for Marda Sina himself, does he really believe that the holographic principle is true? He responded: "Well, I regard this idea as a model, but it is a model that gives a complete mathematical description of quantum spacetime. Therefore, we should take it seriously until someone refutes it or comes up with a better idea. "

Create a five-year high! There are more than 70 movies in the Lunar New Year file.

Starting from November 24th, major cinemas across the country entered the New Year’s Eve screening period. This year, there are more than 70 new films for the Lunar New Year, and the number of new films released has reached a five-year high, with 80% of the new films made in China. The diversified types have given the audience more choices.

The reporter visited several cinemas near the East Third Ring Road in Beijing, and the audience in each cinema was in an endless stream. The newly released film "Three Brigade" and "Detective Conan" became the audience’s first choice.

Create a five-year high! There are more than 70 movies in the Lunar New Year file.

A person in charge of a cinema in Shuangjing, Beijing, said that the number of people watching movies here reached more than 2,000 on the 17th.

The reporter learned that many viewers are also full of expectations for some new films that have not been released. For example, the pre-sale box office of "Twinkle, Twinkle, Twinkle and Bright Stars", which will be released on December 30, has exceeded 247 million yuan.

Create a five-year high! There are more than 70 movies in the Lunar New Year file.

Yin Tengyu, Senior Analyst, Cat Eye Research InstituteThere are more than 70 films released in the Lunar New Year file, and the box office performance of domestic films in this year’s Lunar New Year file is much better than that of imported films.

According to a movie data platform, as of 12 noon on December 17th, the box office of this year’s Lunar New Year has reached 2.337 billion yuan (including pre-sale box office), the number of people watching movies has exceeded 57 million, and the total box office for the whole year has reached 52.757 billion yuan.

Create a five-year high! There are more than 70 movies in the Lunar New Year file.

Rao Shuguang, President of China Film Criticism SocietyWith the release of Chinese New Year movies, I judge that the total box office of China film market is expected to hit 55 billion yuan in 2023.

What is culture? On the word culture

Image source network

The word "culture": its appearance in China can be traced back to the Western Han Dynasty. "Culture" is not only a system of civilizing and educating, but also a system of rites and music. This understanding has been maintained in our country until modern times. The meaning of the word "culture" that we use today is obviously different from that of ancient times. It was introduced from the west through Japanese translation at the end of the 19th century. At that time, there was no definition of the word, and people only used the word "culture" according to their own understanding and needs. According to analysis, there were about three meanings at that time; First, it is synonymous with "civilization"; Second, in a broad sense, it includes spiritual and "civilization" contents; Three, narrow sense, refers to the spiritual content. To this day. The meaning of culture is broader; There are also many people who agree that culture refers to "ideology", and everything outside politics and economy is among them; Others make a broader understanding that everything created by human beings (that is, the integration of material civilization and spiritual civilization) is culture; Besides, some people have other explanations.

In view of the fact that scholars at home and abroad have different opinions on the concept of "culture", it has been suggested that the word "culture" may be a vague concept naturally, and it is difficult to make a clear and complete definition. Instead of pursuing a simple and precise definition, people should determine a flexible range from the perspective of set.

Although there are many definitions of culture, I personally think that it should be the same in many aspects, and we can roughly summarize it into the following three aspects;

First, ideology (also known as ideology) means people’s world outlook, way of thinking, religious beliefs, psychological characteristics, values, moral standards, cognitive ability and so on.

Second, the way of life, that is, people’s attitude towards their food, clothing, housing and transportation, marriage, birth, illness, family life and social production activities, and some forms taken in these aspects.

Third, spiritual materialized products, that is, from the formal point of view, are some material things, but through the material form, they can reflect people’s differences and changes in ideas.

From the above three parts, the scope of culture is basically outlined. But we should pay attention to: the word culture; It should be an organic whole, which is not only the simple addition of the contents of these three parts, but also the mutual influence and premise of the contents of these three parts, and should be organically combined according to a specific sequence.
