Li Huohua and Shen Qihong

　　Recently, a news has become the focus of attention. the Political Bureau of the Communist Party of China (CPC) Central Committee has made a collective study on the development status and trend of blockchain technology, emphasizing that blockchain should be regarded as an important breakthrough for independent innovation of core technology and accelerate the development of blockchain technology and industrial innovation.

　　So what is blockchain technology? What is its development process and current situation? What application scenarios are there in the future? Let’s talk about it here.

　　The Origin and Development of Blockchain Technology

　　When it comes to blockchain, many people may think of Bitcoin. In fact, the two are not the same thing. Blockchain is the underlying technology of Bitcoin.

　　In 2008, a self-proclaimed "Satoshi Nakamoto" published a white paper, hoping to build an electronic money system that won’t be spammed. In January 2009, Bitcoin was officially born, with a total limit of 21 million pieces. The distribution rules are transparent, and there is no central issuer, which is automatically executed by code. The code and operation of Bitcoin are maintained by the participants, and anyone in the world can participate in it.

　　At first, Bitcoin was only circulated among computer geeks. Some people tried it as a new gadget, while others were attracted by its utopian ideal of not spamming and circulating freely. In 2010, there was even a story that a programmer exchanged 10,000 bitcoins for two pizzas. In any case, few people would have thought that bitcoin would have such a great influence later.

　　With the passage of time, bitcoin gradually spread from the computer geek circle. As more and more people participate, capital speculation and speculation follow one after another, and the price of Bitcoin has also started the skyrocketing and plunging mode, which has attracted the attention and reports of some mainstream media and attracted more and more people to study Bitcoin.

　　After studying the code of Bitcoin, people collectively refer to the underlying technology adopted by Bitcoin as blockchain technology, and Bitcoin is the first application of blockchain technology. If bitcoin is compared to bread, then the blockchain is flour. Flour can be made into bread, noodles, rolls, steamed bread and cakes. Similarly, you can use blockchain technology to create bitcoin, and you can also use blockchain technology to do many other things to benefit the whole society.

　　Blockchain is a "trusted machine"

　　As the name implies, blockchain is a combination of "block" and "chain", which is essentially a distributed account book. So, how does this account book keep accounts and how does it work? We might as well use an analogy to illustrate.

　　At the beginning, a group of people first stood up and took a blank piece of paper for bookkeeping, and the system gave this bookkeeper a certain amount of reward (such as 50 bitcoins). After recording the bill, generate an anti-counterfeiting code from this page of bill through encryption algorithm, and copy the bill to all other people at the same time. Next, by calculating a difficult problem, the person who works out first can keep accounts and enjoy the rewards given to the bookkeeper by the system. When recording the bill on the second page, you need to write the anti-counterfeiting code of the bill on the first page at the beginning, and then make an account. After recording, you can also generate an anti-counterfeiting code of the bill on the second page through encryption algorithm, and then copy the bill to everyone else. Then, everyone will compete for the right to charge the bill on the third page by calculating the next difficult problem. This bill will also be marked with the security code of the bill on the first page, and after recording, it will also generate an security code and synchronize the bill to others, and so on. This page-by-page bill is turned into an increasingly thick general ledger through the binding line in sequence, and each participant has one copy.

　　In the above analogy, the bill page by page is called a "block" and the binding line is a "chain". By binding the bill page by page in sequence into a general ledger, a "blockchain" is formed, and its essence is still an account book. Only this account book has one person, and there is no central person or organization. Everyone is equal, and everyone can compete for the right to keep accounts by calculating difficult problems. The whole account book is jointly maintained by all participants.

　　Since there is no central person or organization, how can this jointly maintained account book prevent malicious people from making false accounts or tampering with account book records? Suppose Zhang San grabbed the right to charge the bill on page 100. His good friend Li Si had only 3,000 yuan in his account, but Zhang San helped him secretly change it to 30,000 yuan. After recording the account, he synchronized the account book to others. At this time, others will immediately find that there is something wrong with this account, because there is one account book, and the ins and outs of Li Si’s assets are recorded in the previous account book. Therefore, others will refuse to add the bill on page 100 with wrong records to the general ledger, and will choose another honest person to record the bill on page 100 through calculation problems.

　　Therefore, we can see that blockchain technology has these characteristics: openness and transparency (everyone has one account book, everyone can check it), decentralization (there is no central person or organization), and it cannot be tampered with (because any tampering or false accounting will be discovered).

　　In daily life, many people are used to paying with WeChat and Alipay, and WeChat and Alipay act as bookkeepers. We need to trust this bookkeeper not to misremember or falsify accounts. Blockchain is different. Hackers may attack and modify the account books in a computer, but if they want to really modify the blockchain data, they need to attack more than half of the account books in computers, which is very difficult, especially in a blockchain like Bitcoin. There are tens of thousands of accounting nodes, and one account book is distributed all over the world. Therefore, blockchain technology also has great advantages in security.

　　Openness, transparency, decentralization and non-tampering … … Because of these advantages, the famous British financial magazine The Economist praised the blockchain as a "machine of trust".

　　Blockchain empowers future social development.

　　For more than a decade, blockchain technology has gone from the 1.0 era to the 2.0 era, and now it is moving towards the 3.0 era.

　　In the 1.0 era of blockchain, Bitcoin is a typical representative, mainly recording transaction information simply, with very single function and limited application scenarios. In the 2.0 era of blockchain, the Ethereum project is a typical representative. Different from bitcoin with single function, Ethereum has added the function of "smart contract", which can be simply understood as a program that can be automatically executed. Because of this automatic program, the blockchain has been upgraded from a single-function account book to a world computer, on which people can develop various blockchain applications.

　　As for the 3.0 era of blockchain, just like the 5G era, only after it really comes can people know what it looks like and what new business models and social impacts it will have. The blockchain we are talking about now empowers social development, mainly based on blockchain 2.0.

　　So, in what ways will the blockchain empower social development?

　　The first is the financial industry. The financial industry has to deal with all kinds of accounts every day. The blockchain is essentially a distributed ledger. Using the blockchain as a "trusted machine", it has obvious advantages to use blockchain technology to realize the work that needs multi-party information synchronization, such as bookkeeping, accounting, reimbursement, settlement and tax return. On August 10th last year, Shenzhen Taxation Bureau and Tencent Company launched the blockchain electronic invoice, which realized that the electronic invoice can’t be forged, the data can be inquired, the transaction can be invoiced, and the invoice can be reimbursed, which greatly simplified the traditional financial and taxation workflow.

　　In addition, cross-border payment is also a major application of blockchain in the financial field. Using the advantages of blockchain technology, such as openness, transparency, non-tampering, and distrust of intermediaries, various cumbersome procedures between different banks can be reduced and the process can be accelerated in cross-border payment. On June 25th last year, Alipay launched the cross-border remittance service of e-wallet based on blockchain in Hong Kong. With the Hong Kong version of Alipay, cross-border remittance can be made to Philippine wallet Gcash through blockchain technology. At the press conference, the whole remittance process took only 3 seconds, while it took several days through the traditional cross-border transfer method.

　　In addition to the financial sector, blockchain technology is also promising in business. JD.COM launched the JD.COM Zhizhen Chain a long time ago, using blockchain technology to build an anti-counterfeiting traceability platform, recording the important data of every link of goods from raw material procurement to after-sales, and jointly cracking down on counterfeiting with regulatory authorities, third-party institutions and brands. Last year’s Double Eleven, Tmall International Mall had more than 150 million cross-border goods, which made use of the traceability and non-tampering characteristics of blockchain technology to achieve permanent traceability, prevent false information and protect consumers’ rights and interests.

　　In the field of people’s livelihood, the application prospect of blockchain technology is also very broad. For example, charity can use the openness and transparency of blockchain technology to monitor the flow of each charity fund and ensure that the money finally reaches the recipients.

　　Blockchain technology can also simplify government affairs and realize the interconnection of various functional departments. On November 13th last year, Loudi City, Hunan Province issued the first real estate blockchain electronic certificate, which realized the interconnection between real estate registration and the data of government functional departments such as land, taxation and real estate.

　　Storing data on the blockchain also has legal effect. On June 29 last year, the first case of blockchain deposit in China was pronounced in the first instance of Hangzhou Internet Court, which confirmed the legal effect of using blockchain technology to deposit electronic data and clarified the review and judgment methods of blockchain electronic deposit.

　　For many people who pay attention to privacy protection, blockchain technology is a great boon. All kinds of usage data we leave on the Internet every day, including sensitive information such as identity, mobile phone number, hobbies, shopping records, location, etc., may be leaked directly or indirectly, which will bring great threats and troubles to our lives. Blockchain technology combines cryptography and encryption technology, which can realize the separation of user identity and data, encrypted storage and distributed storage, and make your own data completely in your own hands.

　　The current blockchain technology is still in the early stage of development, just like the Internet around 2000. Although it is full of various possibilities, it is not mature, and there are very few successful large-scale applications, and it is also full of capital speculation and speculation. For this emerging technology, we can’t overestimate its short-term impact, nor can we ignore its long-term changes.

In many people’s impression, western food represents advanced food, and it costs a lot of money to eat a meal.

But there is a restaurant that completely breaks the price barrier.

When you come here and open the menu, you can’t help but exclaim: this is too cheap.

Especially in the face of the rising high prices around, it is unbelievable to look at more than a dozen pieces of pasta on the menu.

Don’t forget that this is still a first-tier city. .

This is the charm of Italian restaurant Saizeriya, which will always impress you with its price.

Compared with other fast food restaurants, Saizeriya is different.

Someone looked up the menu of Saizeriya in 1990s and found that the price more than 20 years ago was twice as expensive as it is now.

In the past 17 years since its opening, Saizeriya has taken a civilian route, focusing on low prices, which has become the western food enlightenment for many children in China.

But Saizeriya’s low price can’t be achieved overnight, and there’s a lot of brain behind it.

Western food "Shaxian snack"

The first time I went to Saizeriya, it was difficult to combine the "Italian restaurant" on the signboard with the rough decoration and humble location.

But when you go in and eat before you come out, no one can escape the law of "real fragrance"

A frequent visitor to Saizeriya said:

I always thought I liked Italian food, until I traveled around Italy last year, only to find out that I only liked Saizeriya.

So popular, knife elder brother summed up two reasons.

1. There has been no price increase for twenty years.

Looking through Saizeriya’s menu, you will find a fact: How has it not changed much in the past twenty years!

Seeing that milk tea has changed from a few dollars to 20 or even 30, Saizeriya still looks so kind.

Unlimited refills for drinks of eight yuan each;

You can eat all kinds of pasta for more than ten yuan, which is much more cost-effective than cooking at home:

Feel free to eat more than 20 pieces of pizza, or 9 inches:

Raist raistlin

More than 40 pieces of red wine to drink casually:

Raist raistlin

Is it cheap? It’s too cheap.

Even if you go through all the items on the menu, the price is affordable, which is only available in Saizeriya.

No wonder some people say that ordering food in Saizeriya is like going back to ten years ago.

Moreover, this price is not a noisy dining environment, but a moment of leisure.

With low price and good environment, it is simply a famous product in the catering industry, the gospel of the student party, and some people even commented that this western restaurant is either for making money or doing charity!

What Saizeriya? Let’s just call it the Virgin Mary.

2, so cheap, can it be delicious?

As the saying goes, cheap goods are not good.

This was put on Saizeriya, and knife elder brother disagreed.

If it’s just cheap, it won’t allow Saizeriya to expand more than 1,000 in the world. In the final analysis, it’s a price war, and customers pay for it, or it’s cost-effective.

Look at this material, which is also very abundant. Squid, shrimp and scallop can realize the freedom of seafood in minutes.

What kind of bicycle is needed at such a price with such ingredients?

There is a saying that Pisa Leah is not as cheap as it is delicious, and the price that is more delicious than it is very expensive. In the same gear, Saizeriya won completely.

Over the years, Saizeriya not only took a look on the Internet with the help of price circle powder, but also found that 80% of the consumers went for the taste of Saizeriya.

Anyone who has eaten Saizeriya later became the "tap water" of this western restaurant. No matter where he is, he misses Saizeriya’s mouth.

In particular, garlic snails and roasted vanilla five-eye intestines are simply classics in the classics, the childhood memories of countless people.

Cheap and delicious, just like the soul label of Saizeriya, it is firmly imprinted in customers’ minds.

But it’s hard not to guess, how did such a low price, coupled with real raw material processing, last for 47 years without going bankrupt?

This has to mention the story behind Saizeriya.

Saizeriya, is there a mine at home?

Many people don’t know that Saizeriya is actually a Japanese catering company.

The founder’s name is Masahiko Masahiro, who founded the Italian restaurant in Saizeriya in 1973. It is said that when the boss was in college, he vowed to open a cheap Italian restaurant chain, and his dream really came true.

▲ Masahiro Tahiko

The reason why it is so cheap has a lot to do with the founder.

1. Who said that delicious food should be expensive?

At that time, Saizeriya was just a small western-style restaurant with only 36 seats in Kawaguchi, Chiba Prefecture.

When Mr. Masahiro Takahiko inherited this restaurant, because it was located above the vegetable market, there were few visitors.

There are also a large number of vegetables piled up at the entrance of the ladder, which further affects the business of the restaurant. After he took over the restaurant, he made up his mind: "Anyway, I want customers to cross the mountains of vegetables and come upstairs for dinner."

Mr. zhengyuan thinks that the high price is the main reason for the decrease of guests, so he reduces the price of dishes to 70% of the original price.

This move has obviously led to the growth of restaurant performance, and even customers queue up.

After a long time, the low price of the restaurant he runs has become a signboard.

He was convinced that "really good things should be cheap and delicious."

Relying on the low price strategy, Saizeriya successfully opened the market.

2, for the sake of efficiency, the kitchen fights.

Generally speaking, the better an enterprise develops, the cost control will be neglected, but Saizeriya is not.

Knife elder brother felt that Saizeriya’s cost savings can be summarized in several points.

The first is laziness.

As an enterprise, Saizeriya is too lazy to cook without a kitchen knife.

Cooking by what? Central kitchen.

Pre-processing all dishes through the central kitchen, and then sending semi-finished products to nearby stores can reduce the time cost.

Moreover, the function of the chef is greatly reduced, and only trained employees can engage in standardized operations. Greatly reduced labor costs and saved time for customers.

It takes only 9 minutes and 58 seconds to process and serve on the spot and complete 15 dishes.

Even the site selection, Saizeriya is too lazy to choose the location, and he will choose the closed restaurant stores, decorate them casually, ensure cleanliness and comfort, and start business.

Followed by essence.

Saizeriya is responsible for the cultivation of ingredients, the production and processing, and the store cooking.

Therefore, it can be speculated that the overall model of Saizeriya is probably: the place of production is taken out-processed in the central kitchen-sent to the store.

What do you mean, fat water doesn’t flow from outsiders? This is it.

Finally, the province.

Saizeriya’s low price depends on everyone’s saving.

The Japanese once filmed a program to unveil Saizeriya’s low-priced The Secret Behind.

For example, mopping the floor, such a common and simple thing, is calculated by efficiency here in Saizeriya.

This mop is equipped with an automatic water dispenser, and water can flow out of the mop with a light press. One to two, save a lot of time to wash the mop! The compressed time is just enough to go to the kitchen to help.

There is also a lot of knowledge in the waiter’s service.

Saizeriya has done a special test, and it is much more efficient for employees to serve food with their hands than trays.

And the homemade tomato cutter, placed directly in the middle, can be cut neatly and beautifully in five seconds.

On the whole, Saizeriya’s process operation stunned other entrepreneurs.

And this is also the most powerful proof to keep the price low and ensure the quality.

In addition, Saizeriya has an indicator called "turnover per hour", which is the turnover realized by an employee in one hour.

Saizeriya attaches great importance to improving this index, because as soon as the "man-hour turnover" goes up, the number of customers handled by each employee will increase accordingly, and it can be maintained with less manpower.

It is worthy of being an Italian "Shaxian snack" that has stood for 47 years in a row. Not everyone can control the cost like this.

Because of this, Saizeriya has also been vomited by some diners.

Saizeriya, don’t be too happy.

Because of this processing method of pre-finished products, it is actually the operation of reheating quick-frozen products.

It is essentially impossible to adjust the taste of customers.

▲ After-kitchen pre-finished product processing

In other words, Saizeriya has been training customers to adapt themselves.

As a catering industry, consumers and businesses usually try to adjust their tastes to each other, but Saizeriya, like a love rat, is unwilling to make changes for each other.

One more thing, too few people know about Saizeriya. Because to save money, all kinds of endorsements and event marketing are not available. Therefore, residents of cities without Saizeriya have never heard of it.

These are knife elder brother’s worries. On the whole, Saizeriya’s advantages are still stronger than others.

In particular, compared with the restaurants in Babela, which used to compete with it, it has long declined, and some of them may have never heard of it after 00.

Babela is also an Italian restaurant opened in China. It was founded in Shanghai in 2005 and has more than 200 stores nationwide.

At that time, there was usually a long queue at the entrance of Babela!

But now it’s hard for you to find its store.

One of the main reasons for bankruptcy is that the eyes are superior and the eyes are inferior.

When there were a large number of customers, Babela was impatient and began to raise prices to highlight his own style.

However, because the food itself is a third-rate taste, we must position the price of Michelin for ourselves.

Customers are not fools, and they can choose Pizza Hut or other western restaurants at the same price. Over time, how Babela didn’t exist is almost forgotten by everyone.

This gave Saizeriya more room for development and made up for the shortage of this gear.

During the epidemic, Saizeriya opened three stores in succession, with a 50% discount. And it is planned to open 300 stores in Guangdong Province within five years.

Compared with other restaurants, Saizeriya is simply a mudslide, standing firm in the market at a low price.

Look at Yoshinoya, who couldn’t stand it before. He is also a Japanese chain restaurant with the same expansion model, but he closed hundreds of stores overnight and lost more than 600 million yuan.

The reason is the service retrogression. Inadequate staff training, casual ordering, slow serving speed, and decreased food quality, which is expensive and not delicious.

You see, once the service and quality cannot be guaranteed, even if you are famous again, you will be abandoned by the market.

Therefore, even in Saizeriya, which is famous for its cost performance, knife elder brother should give a vaccination. Don’t float, remember your initial heart.

(Reporter Feng Qiyu)

Teacher Zhu is instructing students to learn mathematics.

　　Teacher Zhu’s paintings use parabola, hyperbola, ellipse, cubic parabola and other functional curves to show the beauty of smooth and soft curves.

　　Mathematics in senior high schools and universities always gives people the impression that it is abstract and boring and difficult to learn, and many students are afraid of difficulties in mathematics classes. Yesterday, in the math class of Yangzhou Higher Vocational and Technical School, the reporter of Yangzi Evening News saw the clever and beautiful picture drawn by the math teacher with "function curve" on the blackboard, which was unforgettable. In class, the teacher painted brilliantly and spoke vividly, and the students listened and remembered with great care. Do you envy such a "fancy math class"?

　　He is a "painter" delayed by mathematics.

　　A piece of chalk painting drawn by "mathematical language"

　　Although there are only a few strokes, they are vivid and vivid, just like works of art

　　Zhu Zhonghai, director of the Basic Education Department of Yangzhou Higher Vocational and Technical School, is a math teacher. At the age of 57, he has been teaching mathematics for 35 years. Yangzi Evening News reporter found Mr. Zhu yesterday and saw the chalk paintings he "created" last year and this year. The reason why we should use the formal word "creation" is because these chalk paintings in the eyes of reporters are vivid and vivid, just like works of art, although there are only a few strokes. Without a certain skill, it can’t be done just by some mathematical curves.

　　The Yangzi Evening News reporter noticed that these chalk paintings drawn in "mathematical language" include slender women, elderly people, naughty children and naughty kittens. From the action point of view, some are looking at the distance, some are enjoying flowers, some are dancing, some are playing the piano, some are picking, some are playing ball games, and some are observing bugs; From the color point of view, some have only one color, white or pink, and some have two colors, but no more than three colors. Whether it is one color or a limited number of two or three colors, the works are vivid and vivid, and a few gentle curves are combined slightly, which gives the works vitality and shows the author’s skillful and superb painting skills. In the corner of each painting, some of them are written with the titles of "childlike interest", "picking", "returning from the storm" and "sports beauty". Each painting is signed "Xiaohai", and the running script font is as smooth and agile as the picture. Teacher Zhu, who is nearly sixty years old, calls himself "little", which reflects his frank and modest character and attitude towards work.

　　"Teacher Zhu’s math class is nice, interesting and really beautiful! My classmates and I didn’t expect that the boring and difficult mathematical figures, those parabolas and function curves, came to Teacher Zhu, and when they were combined and matched, they were all a painting, and we were all attracted by him. " A classmate told the Yangzi Evening News reporter that when Mr. Zhu was in class, the whole blackboard was a blackboard newspaper with different fonts, large and small intervals, different colors and vivid illustrations. After class, the students in charge of health are reluctant to erase the blackboard. It’s really beautiful.

　　Teacher Zhu told the Yangzi Evening News reporter that he had taught high school mathematics, secondary vocational mathematics and higher vocational mathematics. "I’ve been thinking. In math class, can you make students’ eyes light up, calm their hearts and focus their attention on the blackboard? " Teacher Zhu told the Yangzi Evening News reporter that teachers’ professional ability is housekeeping skills, and their basic skills are not only "facade" but also core competitiveness. Mainly reflected in the calligraphy, pen, chalk and "three words and two words (painting)" in speech and painting, this is not achieved overnight, and it needs long-term tempering and accumulation. I practice calligraphy and painting every day and make progress every day.

　　"When I was teaching functions last year, when I talked about curves and equations, I thought that the beauty in life is everywhere, and the gentle curves in life are vivid and smart. After pondering and thinking, I created a series of chalk sketches" Dancing Functions ". Some are painted on the spot in class, some are painted in advance, and each curve can be defined, beautiful and related. The key is how to use them well and how to combine them so that they can present the most beautiful visual effect in the most suitable position. The students’ emotions were suddenly mobilized and attracted by every beautifully conceived function curve. " Recalling the "function curve drawing", Teacher Zhu said excitedly.

　　Painting depends entirely on self-study

　　Attract students with the "unique skills of board painting" with the integration of arts and sciences

　　"No matter which class I talk about, I should make students feel the charm of mathematics according to the culture behind the theme of the course and the related math stories. I have written a book" The Starry Sky of Mathematics "from my decades of teaching experience, which has now been published."

　　For Mr. Zhu, chalk painting is also gradual. The students said that he had a unique skill in drawing "unique skills" with chalk, and he could draw very, very round without compasses. Several times after class, the students verified it with compasses, and the results showed that it was almost the same, so the students all took it. "Of course, I didn’t draw a circle at first, but I painted a lot. I painted with my heart and accumulated it to a certain extent, and it became." Teacher Zhu told the Yangzi Evening News reporter.

　　"I use appropriate teaching methods and a blend of arts and sciences to teach. In addition to mathematics, I like literature and art very much, especially in vocational schools. I try my best to tell and interpret it in liberal arts during the teaching process. The examples I give are all examples from my classmates’ familiar life, combined with the students’ majors and what majors they study. What kind of relevant examples are given? " In recent years, Mr. Zhu has published nearly 100 essays, poems and prose poems. He doesn’t want to make any achievements in literature and art, but wants to improve his literary and artistic accomplishment and increase the thickness of his comprehensive quality, so as to promote himself to teach mathematics better, make his math class more agile and be accepted and liked by students. The Yangzi Evening News reporter learned that after Mr. Zhu created the painting "Dancing Function", he successively created a series of works such as "Community Style", "Rhythm on the Blackboard" and "Beauty of Points, Lines and Surfaces", totaling more than 200 paintings.

　　"Mathematics learning is abstract and boring. I decorate the classroom with sketches to make students’ eyes light up." Teacher Zhu told the Yangzi Evening News reporter, "I don’t specialize in painting, but because of my love and persistence, I am confident that I can draw well and influence my students."

　　He is like this in the eyes of his colleagues.

　　I can write poetry and prose, understand photography and have feelings.

　　"He has one share of magic to seize students."

　　"Teacher Zhu is a senior math teacher in our school and a middle-level cadre. He is recognized as a teacher with humanistic feelings in our school." Teacher Zhu’s colleague told the Yangzi Evening News reporter that teacher Zhu has many talents, not only teaching mathematics well, but also writing poetry, prose and photography, which is very popular among teachers and students. Mr. Zhu has won the title of National Excellent Teacher and the National Excellent Professor Medal. He is a young and middle-aged expert with outstanding achievements and the winner of the first batch of national backbone teachers in the "333 Project" in Jiangsu Province. Judging from the years of working and getting along with Mr. Zhu, he is well-deserved and worthy of these achievements and honors.

　　"His image and temperament are no different from everyone else’s, but there seems to be some magic in him that can catch students at once." A young teacher told the Yangzi Evening News reporter that the school has requirements for information-based teaching, and many young teachers may rely too much on PPT. After reading Mr. Zhu’s class, they were really inspired. Mr. Zhu, an uncle, used mathematical curves to draw beautiful and fashionable paintings, so it is no wonder that students like it so much. In fact, PPT teaching and classroom blackboard writing and blackboard drawing are not contradictory. If they are organically combined, the classroom efficiency will be higher.

　　He, deeply confided in his heart.

　　"I think PPT teaching should be moderate now. As a teacher, the essence of some teaching traditions can’t be lost, such as writing on the blackboard. In my opinion, writing on the blackboard on the spot, calculating and reasoning on the blackboard, and letting students learn and understand the reasoning process intuitively will definitely leave a deep impression. I also want to take my own practical actions, which I have persisted in for many years ‘ Old ox ’ The habit of writing on the blackboard sets an example for young teachers and influences them. " Teacher Zhu said that his teaching pursuit is to stand well in the classroom and make it full of vitality. Instead of filling the students’ baskets, we light the lights and use one soul to wake up another. "No job is easy to do. Instead of complaining uselessly and needlessly, it is better to calm down and do your own job in a down-to-earth manner. I don’t expect what I do to be brilliant, but at least I can make myself progress and get better gradually." (Correspondent Grace Wai Wong Yangzi Evening News/Zi Niu News reporter Yong Chen)

　　CCTV News:According to "China" WeChat WeChat official account news, recently, the "Jiangxi student Hu Mouyu incident" continued to attract the attention of netizens, and related rumors on the Internet continued to ferment, seriously misleading public judgment and causing adverse social impact. In this regard, the network information department urged the website platform to earnestly fulfill the main responsibility of information content management, and severely cracked down on online opportunities to spread rumors and malicious marketing hype. Tik Tok, Tencent, Weibo, Aauto Quicker, Baidu, Bili Bili, Xiaohongshu and other key website platforms have carried out in-depth investigation and rectification, and accumulated 1,894 illegal and illegal accounts, resolutely curbing the momentum of bottomless rumors and speculation, and earnestly safeguarding a good network ecology. Some typical cases are reported as follows:

　　1. Fabricate the reasons for the bizarre disappearance. Since the incident, some online accounts have speculated on the reasons for Hu Mouyu’s disappearance for no reason, and fabricated online rumors at will, causing panic among the masses and stirring up opposing feelings. Some deliberately fabricated Hu Mouyu as a special blood type. For example, Baidu account "daring18425" said that "the school bought a lot of surgical equipment, and Xiao Hu was taken for research because he had panda blood". Some fabricated rumor information about Hu Mouyu’s murder through detailed description, which is very confusing and inflammatory. For example, Weibo account "7812608894" posted a post that "Hu Mouyu must have been deceived to the mountain, and then the murderer strangled his neck with a rope from behind while he was not paying attention, and then hung it on a tree to pretend to be suicide". Some maliciously speculated that Hu Mouyu’s organ was transplanted for sale, such as the Tik Tok account "hjd1475" posting the audio of "The doctor voiced that Hu Mouyu was transferred for organ transplantation". In addition, Aauto Quicker "China Senior Appraiser." Accounts such as WeChat "Xiaohuang Chat Entertainment" and Weibo "Happy Mango Meat" also concocted the so-called "many students in this school have disappeared" and "Hu Mouyu has been sterilized by the chemistry teacher"Rumor information, causing bad social impact.

　　2. Fabricate the progress of the incident investigation. In the search process of public security organs, some online accounts took advantage of the public’s high concern about the progress of the incident and fabricated the so-called "latest news of Hu Mouyu’s incident" to attract attention, bias the rhythm and mislead cognitive judgment. One typical example is that WeChat WeChat official account "Hundred Herbs Meet the Spring Breeze" released "The latest news of Hu Mouyu, the car was buried, and the underground passage of the laboratory was discovered in the back hill". Tik Tok’s account "Li Zuopeng from the Media" released a video of "Li Changyu, the top detective in China, has been involved in Hu Mouyu’s case". Aauto Quicker’s account "Northeast Panther Positive Energy" released a video called "Hu Mouyu found it, with incomplete organs, where did it go?". The accounts of WeChat "TT Chatting Gossip", Aauto Quicker "Wonderful Movie of Lao Liang" and Weibo "Going to the hospital to disperse people" also fabricated the remarks that "broken bones were found in the septic tank of the school", "white cloth was found on the second floor of the school" and "bloody clothes were found in the Woods on the back hillside of the school". These online rumors have no factual basis and are intended to disturb people’s hearts, which is not only not conducive to the investigation of the incident, but also causes great interference and is very bad in nature.

　　3. Identity of persons involved in the counterfeiting incident. Some online accounts pretend to be event-related personnel in various ways, taking the opportunity to spread false information. Among them, Baidu account "ilusions" called for help online, claiming to be Hu Mouyu himself, and has been kidnapped and imprisoned. Tik Tok’s "SSYG 800", "96222866030" and other accounts changed their personal signatures to "Sister Hu Mouyu" and "Cousin Hu Mouyu", posing as relatives of the parties concerned. Aauto Quicker’s "Uncle Hu Mouyu", "Brother Hu Mouyu" and "Dad Hu Mouyu" have published false videos many times by setting up new user avatars and changing user nicknames. There are also individual accounts posing as school chemistry teachers, posting videos that threaten family members’ privacy.

　　4. There is no hot spot for bottom-line speculation. Some online accounts deliberately take advantage of hot events, malicious marketing hype, misleading netizens. What is more prominent is that Aauto Quicker’s accounts such as "Tears Countercurrent" and "Mainlanders 998" associated "Hu Mouyu Incident" with other events for no reason, hyped it up and played up negative emotions. Tik Tok’s account "Yu Ge sees the world" and Xiaohongshu’s account "63E20" edited and released pictures, audio and video information of the parties and their families in batches, hyping the so-called clues of relatives and friends. Tik Tok’s account "Teacher Yigu" speculates on Hu Mouyu’s personal safety through superstition, and takes the opportunity to seek improper benefits.

　　The relevant person in charge of the Central Network Information Office said that after the Hu Mouyu incident, the majority of netizens were very concerned about the progress of the incident and the investigation. At the same time, some lawless elements fabricated rumors on the Internet without a bottom line and interfered with the trend of public opinion, which not only challenged the basic moral bottom line of society, but also violated the requirements of relevant laws and regulations. For such information and accounts, the network information department will never tolerate it and will continue to crack down. At the same time, it also appeals to the majority of netizens to improve their ability to distinguish, not to believe in rumors, not to spread rumors, to actively participate in supervision and reporting, and to actively provide relevant clues to jointly create a clean and honest cyberspace.
