Please indicate "Shanghai Education" on the WeChat of Shanghai Municipal Education Commission.

Say goodbye to the familiar campus and classroom, and meet the students in the "cloud" every day. How to make the students at home on the other side of the screen study actively and with peace of mind? The primary and secondary school teachers in Shanghai incarnate "Avalokitesvara" to show their magical powers, attract children to study efficiently with ingenious online class skills, and care for them through various channels after class, so that children can feel the warm love of teachers through the screen.

After careful design, teachers’ online teaching blackboard books are not only as neat and beautiful as offline classes, but also innovate and practice according to the characteristics of online teaching to help students better master the knowledge system. Let’s take a look at these "most beautiful online blackboard books" with Xiaoyu!

Songjiang Sijing experimental school affiliated to Shanghai University of Engineering Science

Small blackboard design plays a big role

Online teaching, with the help of the network platform, has turned some "impossible" of offline teaching into reality. Teacher Mao Kaijie of Songjiang Sijing Experimental School affiliated to Shanghai University of Engineering Science discovered the "evolution of blackboard" in online teaching.

At ordinary times, one blackboard in the classroom has become 50, and at the same time, the blackboard that can only write offline has become a multifunctional blackboard that can write and call a lot of mathematical tools.

Of course, there are more blackboards, which does not mean that teachers can write on the blackboard at will, especially in math class, because its subject characteristics, in addition to being refined, also need to have more rigorous logic. In the online teaching platform, using the following three forms to write on the blackboard can make online teaching more "memorable".

1. Add color to the text, and the focus will naturally come. Multi-color writing is not only for beauty, but more importantly, it plays a role in highlighting key points, breaking through difficulties and correcting error-prone points. Adding arrows can make the meaning more concise and intuitive.

2. Words with pictures make sense. Daily teaching needs time-consuming and laborious stickers and forms, and online teaching can be done with a picture. You can take a screenshot of the video or upload the picture to the cloud disk in advance and call it.

3. Ruler plus material, graphics come at will. The influence of teacher’s demonstration is self-evident, especially the beauty and standardization in writing and drawing. In the column calculation, we ask students to draw the equal sign straight, and the teacher must do it first. You can easily get standardized symbols and lines by calling ruler tools or inserting text for input. Of course, there are also some plane graphics and three-dimensional graphics, which can be easily drawn by teachers simply by directly transferring them from teaching materials.

Changning district yuyuan rd 1 ST primary school

"By combing pictures and texts and connecting symbols, we can clarify the logical relationship between knowledge and summarize the learning focus of this lesson", "To solve problems, build a class blackboard with logical thinking context", "Make clever use of classroom resources in the air, optimize and reorganize by means of symbols and pictures, and design and construct a structured blackboard" … Teacher Dai Yanbin from Xianghong Branch, Yuyi Primary School, Changning District, Shanghai, in the online teaching practice of natural science in the fourth grade, based on students’ learning situation and unit learning content, Carefully designed electronic blackboard books with various forms, scientific contents and convenient for students to read, which are displayed in the online discussion area of each "cloud" class, to build a scaffold for students’ thinking, consolidate scientific concepts, guide them to analyze and solve problems by using the methods they have learned on the basis of understanding knowledge, and improve students’ scientific practical ability and scientific literacy.

In the lesson "How to Make Sinking Objects Float", Mr. Dai extracted relevant materials from the classroom resources in the air, and presented the contents of electronic blackboard books in two columns with brief explanations at the top of the pictures, so as to guide students to consolidate their scientific knowledge and learn the scientific methods to solve problems, and realize the extensive application of buoyancy in production and life.

In the teaching of "Buoyancy of Air", Mr. Dai’s electronic blackboard book revolves around the core content of this lesson, "Buoyancy of Air and its Application", which is organized in an illustrated way and presented in a question-and-answer way, listing "What is buoyancy of air?" "What is the relationship between the buoyancy of air on an object and it?" "What is the relationship between the ups and downs of objects in the air?" "What are the applications of air buoyancy in production and life?" These four key issues. Problem-oriented, leading students to think and solve doubts in the process of reading electronic blackboard books, cultivating students’ problem-solving consciousness and stimulating students’ interest in scientific inquiry.

Shiba junior high school

Writing on the blackboard in class: teachers’ operation show

"I can’t let my students see clearly" is a problem that teachers often pay attention to and care about. No, the teachers of the eighth junior high school in the city give full play to their majors and use tools to try their best to provide students with a good class experience.

Li Songjia, a math teacher who was suddenly isolated at home, was a little disappointed at first. The community is suddenly closed, and the handwriting board is too late to prepare. Writing on the blackboard with the mouse can easily become messy. The same challenge is very common in science teaching. Teacher Li immediately "asked for help" in the teaching and research group of the school mathematics group. It turned out that many seniors in the group grafted the micro-lesson treasure with the auxiliary camera function of the teaching platform and put the blackboard on paper! The clear and complete answering process is presented on the screen. There are also some teachers who set up mobile devices directly and use the rear camera to shoot blackboard books, just to present the best teaching state to students! In order to make students have a better learning effect, the teachers of all teaching and research groups and preparation groups have used their brains and tried their best.

Nanyang junior high school

"The classroom is complete with blackboard writing"

Teachers of Nanyang junior high school are equipped with black (white) boards at home. The combination of "computer+handwriting board" is also favored by teachers. It is both chalk and red pen, which makes teachers play freely in online teaching guidance.

Yangpu junior high school

How can teachers and students interact effectively in the classroom through the screen? This is a practical problem that has been puzzling teachers and students. In order to solve this difficulty, the teaching team of Yangpu Junior High School in Shanghai carefully designed blackboard writing with pictures and texts in teaching practice:

The blackboard writing of teachers in mathematics teaching and research group

The teachers of the mathematics teaching and research group appeared in formal attire and explained "the area problem of a linear function" in the form of a special course of thinking expansion. In the design of blackboard writing, teachers consider using multi-equipment to teach, computer screen to monitor students’ class situation, tablet writing problem-solving process, and sometimes use the interactive annotation function of online conference platform to enhance classroom interaction. The teacher then marked it with different colors to make the blackboard key.

The blackboard writing of English teaching and research group teachers

In order to empower the classroom with information technology and enhance the effectiveness of the classroom. Teachers of the English Teaching and Research Group re-edited the high-quality resources in the air classroom for our use, guided the students’ thinking through the flow chart in the blackboard, let the students understand the truth that time is precious, and skillfully integrated the content of Lide Shuren into the subject teaching to achieve the effect of moistening things and being silent.

Anting high school

The "capacitance pen" and "mouse" in the hands of online teaching teachers still seem to be less handy than the "chalk head" in the classroom. No matter whether it is in regular script or song style, all of them become "earthworms", and the effect of online blackboard writing is always a little worse. However, the electronic blackboard written by teacher Chen Yi from Anting High School makes people shine at the moment, and suddenly reminds them of the long-lost blackboard in the classroom. She wrote the blackboard in advance with related apps on the tablet computer, which is convenient for students to use as a reference when reviewing and sorting out knowledge points.

Baoshan district 2 nd central primary school

Since the online teaching was launched, the teachers of the Second Central Primary School in Baoshan District of Shanghai have used the online teaching platform to make children feel at home. Teachers also show their magical powers:

Teacher Xia Tian’s practical class is guided by core literacy, starting with simple mathematical problems in daily life, so that students can understand the methods of list enumeration and feel the value of orderly thinking and the application of mathematics in life in the process of solving problems.

There is also teacher Nancy who combines subject resources to cultivate children’s thinking ability and add color to online teaching.

Teacher Nancy teaches the blackboard writing in the third class of Parallel online.

shanghaipudong foreign languages school

In order to help students adapt to modern education, and at the same time to cope with the sudden online teaching at any time, the teaching team of the international course class of Pudong Foreign Language School affiliated to Shanghai International Studies University has adopted electronic means with distinctive subject characteristics and strong interactive experience in advance in teaching materials, blackboard writing, homework and other aspects to ensure the effectiveness of online teaching.

In science teaching, teachers pay the most attention to clear logical deduction and detailed answers. Jiang Lili, a math teacher, uses a digital handwriting board to show the deduction process in real time, with brief drawings to show unimaginable three-dimensional thinking.

Electronic blackboard writing in mathematics classroom

Feng Yanying, a physics teacher, made her own electronic school-based notes, marking the key points and standardized answers of each class in detail, so that students can quickly locate notes and master knowledge points.

Physical electronic school-based notes

Although it is an online teaching mode, students can still interact face to face with teachers and students, see the familiar handwriting of teachers and receive professional and meticulous guidance. The teachers’ team used various and sufficient electronic means, which not only kept their own teaching characteristics, but also improved the teaching effect and learning enthusiasm, and tried their best to help every student grow sturdily!

Jinshan primary school

Ge Jiayi, a first-grade math teacher in Jinshan Primary School, used mind maps to sort out knowledge, pay attention to the correspondence between algorithms and arithmetic, and improve students’ understanding of the diversity of algorithms in the teaching of Unit 4 "Two Numbers Plus One Number".

Ni Shengji, a Chinese teacher at Jinshan Primary School, designed the blackboard book "Spider Shop Opening" for the second grade, which helps students to sort out the process of spider shop opening three times in the form of schematic diagram and presents the key information of the text, paving the way for guiding students to grasp these key information to tell stories, aiming at cultivating students’ ability to tell stories.

Wang Ling, a science teacher at Jinshan Primary School, wrote on the blackboard in the last lesson of Fish and Snails in Grade One, mainly sorting out the knowledge points of the whole unit and explaining the key contents of the four lessons respectively.

The material is provided by the relevant district education bureau.

"Governing the country for three years" industrial articles

  Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the general secretary has put forward a series of new ideas, new ideas and new strategies for governing the country, led the industrial development with the strategy of innovation-driven development and the strategy of manufacturing a strong country, and promoted the industrial transformation and upgrading of China with the extraordinary determination of reform and perseverance. The industrial production maintained a medium-high growth, the production of emerging industries grew rapidly, and the traditional industries accelerated the transformation and upgrading, which played an important supporting role in realizing the medium-high growth of the national economy and moving towards the middle and high-end level.

  First, the industry maintained medium and high-speed growth, and the results of improving quality and increasing efficiency were obvious.

  (A) China’s industry has maintained a moderate and high-speed growth in the complex and severe economic environment. From 2013 to 2015, the added value of China’s industrial enterprises above designated size increased by 8% annually. In terms of categories, the manufacturing industry grew at an average annual rate of 9%, the mining industry at an average annual rate of 4.5%, and the electricity, heat, gas and water production and supply industries at an average annual rate of 3.8%. In terms of economic types, state-owned holding enterprises grew by 4.4% annually; Collective enterprises grew at an average annual rate of 2.4%, joint-stock enterprises grew at an average annual rate of 9.3%, and foreign-invested enterprises from Hong Kong, Macao and Taiwan grew at an average annual rate of 6.1%. Private enterprises grew at an average annual rate of 10.4%. In recent years, the recovery of the world economy is weak, the phenomenon of weak external demand has not changed significantly, the rebound of major developed economies is less than expected, and the growth rate of emerging economies has generally declined. According to the data of the United Nations Industrial Development Organization, during the period from 2013 to 2015, the annual growth rate of the world manufacturing industry was only in the range of 2% to 4%, and China’s industrial growth was still in the forefront among the world’s major economies. Under the background that the economic environment at home and abroad tends to be complicated and severe, it is especially difficult for China’s industry to achieve medium and high-speed growth.

  (2) The overall efficiency level of enterprises is good, and the unit labor output has been significantly improved. From 2013 to 2015, the main business income of industrial enterprises above designated size increased by 6.3% annually and the total profit increased by 4.2% annually. Among them, the main business income of manufacturing industry increased by 7.3% annually, and the total profit increased by 8.6% annually, both higher than the overall level of industries above designated size. From the per capita income of main business, the increase of unit labor output reflects the progress of improving quality and efficiency of enterprises. In 2015, the per capita main business income of industrial enterprises above designated size reached 1.174 million yuan, an increase of 186,000 yuan or 18.9% in three years compared with the level of 988,000 yuan in 2012.

  Second, innovation drives kinetic energy conversion, and emerging industries form new growth points.

  Since the 18th National Congress of the Communist Party of China, high-tech industries have developed rapidly and improved their efficiency, becoming an advantageous industry leading the transformation of industrial economic kinetic energy. Emerging industries and products are constantly emerging, and new kinetic energy and power show their vitality and become new growth points in the industrial economy.

  (A) the rapid growth of high-tech industries, leading role significantly enhanced. From 2013 to 2015, the added value of high-tech industries increased by 11.4% annually, which was 3.4 percentage points higher than that of all industries above designated size. The main business income and total profit increased by 9.9% and 14.4% annually, respectively, and the growth rate was 3.6 and 10.2 percentage points higher than that of all industries above designated size, which reflected that the driving role of high-tech industries was significantly enhanced under the innovation-driven development strategy.

  (2) The development of new kinetic energy within the industry shows vitality, and technological progress has become an important source of power for industrial growth. From 2013 to 2015, some emerging industries developed rapidly. The added value of urban rail transit equipment manufacturing industry grew at an average annual rate of 32.2%, communication equipment manufacturing industry grew at an average annual rate of 20.3%, biopharmaceutical manufacturing industry grew at an average annual rate of 13%, electronics and electrical machinery special equipment manufacturing industry grew at an average annual rate of 12.4%, and electronic device manufacturing industry grew at an average annual rate of 12.3%.

  (3) Emerging industrial products release growth potential, and intelligent manufacturing has become a new engine driven by leading innovation. In 2015, new, intelligent, automated equipment and high-end information and electronic products became new growth points. Compared with the previous year, the output of new energy vehicles increased by 161.2%, industrial robots increased by 21.7%, smart TVs increased by 14.9%, and smart phones increased by 11.3%. The output of vending machines and ticket vending machines increased exponentially, and solar cells (photovoltaic cells), optical fibers, optical cables, optoelectronic devices, emus and urban rails increased.

  Third, the economic structure optimization has achieved remarkable results, and industrial transformation and upgrading have been steadily advanced.

  Since the 18th National Congress of the Communist Party of China, the industrial economic structure has been continuously optimized, and the advantageous industries with the change of production structure and profit growth among industries reflect the characteristics of industrial upgrading. The transformation of the internal development mode of the industry is also going on. Traditional industries are transformed through optimal allocation. New energy, new materials and new technologies promote the upgrading of product structure, and the increase of production added value promotes the value of the industrial chain.

  (1) The industrial production structure continued to show positive changes. Since the 18th National Congress of the Communist Party of China, the proportion of high-tech industries has increased year after year, and the increase rate is increasing year by year. From 2013 to 2015, the added value of high-tech industries accounted for 9.9%, 10.6% and 11.8% of all industries above designated size. The equipment manufacturing industry has become the industry with the largest proportion, accounting for 31.8% of all industries above designated size in 2015; The proportion of consumer goods manufacturing industry is rising, and the proportion of added value from 2013 to 2015 is 24.5%, 25.1% and 26.1% in turn; The proportion of high energy-consuming industries and upstream mining industry is decreasing year by year. From 2013 to 2015, the proportion of the six high energy-consuming industries is 28.9%, 28.4% and 27.8% respectively, and the proportion of mining industry is 12.4%, 11% and 8.6% respectively, which shows that the situation that industrial economic development relies too much on resources is improving.

  (2) Industries with rapid profit growth show the characteristics of industrial upgrading. From 2013 to 2015, among the above-scale industries in China, the equipment manufacturing industry realized a total profit of 6,668.3 billion yuan, with an average annual growth rate of 10.8%, which was 6.6 percentage points higher than that of the above-scale industries; The total profit of the consumer goods manufacturing industry was 5,094.3 billion yuan, with an average annual growth rate of 8.8%, which was 4.6 percentage points higher than that of industries above designated size. With the gradual improvement of residents’ living standards and the continuous increase of family car consumption, automobile manufacturing industry has become the industry that creates the most profits among 41 industrial categories, with a total profit of 1,717 billion yuan in three years, with an average annual profit growth rate of 14.4%.

  (3) Traditional industries have achieved transformation and development through upgrading the value of industrial chain and optimizing product structure. While the proportion of traditional industries in industry is generally declining, its structural adjustment is also deepening, and the transformation and upgrading of development mode are promoted through the optimal allocation of production share and product structure. Judging from the changes in the internal structure of traditional industries, the production share is more adjusted to the industrial chain links with high added value. For example, in iron and steel and non-ferrous industries, the production share of smelting industry with relatively low added value decreases and the growth rate decreases, while the production share of calendering industry with relatively high added value increases. From 2013 to 2015, steel calendering production achieved a relatively fast annual growth of 8.6%; The production of non-ferrous metal calendering increased by 13.5% and the profit increased by 8.8% annually. In addition, the average annual production growth rate of synthetic materials manufacturing, special chemical products manufacturing, glass fiber and glass fiber reinforced plastic products manufacturing in these three years is above 10%. The product structure is also being adjusted in the direction of better quality and higher technical content. For example, in the building materials industry, the output growth of traditional cement and flat glass is relatively slow, while the output of tempered glass, laminated glass and insulating glass with high technical content increased by 7.4%, 11.1% and 14.3% respectively from 2013 to 2015; From 2013 to 2015, the average annual profit growth of new building materials such as lightweight building materials, waterproof building materials, heat insulation and sound insulation materials all exceeded 10%. Such as in the chemical industry,The output of new materials such as carbon fiber reinforced composites and rare earth magnetic materials all achieved double-digit growth in 2015.

  Four, industrial exports continued to grow, and the export of equipment manufacturing industry became the pillar.

  (1) Industrial exports continued to grow. From 2013 to 2015, the export delivery value of industrial enterprises above designated size reached 35,298.6 billion yuan, with an average annual growth rate of 3.1%. Faced with the weak recovery of the world economy and the obvious weakening of external demand, industrial exports still maintain a certain speed, and it is very difficult for the annual export scale of industrial products to exceed 10 trillion yuan.

  (2) The equipment manufacturing industry has become a pillar industry for the export of industrial products. From 2013 to 2015, the equipment manufacturing industry achieved a total of 22,804 billion yuan in export delivery value, accounting for 64.6% of all industrial export delivery value above designated size. Equipment and technology-intensive mechanical and electrical products have replaced labor-intensive textile industrial products as the main export force, which reflects that under the new round of high-level national strategy of opening to the outside world, the structure of China’s industrial exports has been optimized, and the comparative advantage of foreign trade has gradually shifted to the middle and high-end technology and capital competition fields.

  (3) Exports of some industries maintained rapid growth. From 2013 to 2015, the communication equipment manufacturing industry in export delivery value grew at an average annual rate of 13.6%, the radio and television equipment manufacturing industry grew at an average annual rate of 11.1%, the electronic and electrical machinery special equipment manufacturing industry grew at an average annual rate of 10.5%, and the automobile parts and accessories manufacturing industry grew at an average annual rate of 10.2%. Facts have proved that the supply-side upgrade of exports is still promising in the overall downturn of external demand. It is a feasible way for industrial exports to develop to a higher level and a higher level by broadening the space for international development according to the quality improvement, aiming at market segments to achieve overseas competition breakthroughs, and achieving win-win industrial linkages through holding a group to the sea.

Emotional value: Is the business really "profitable"?

  "Pinch" is becoming the new favorite of young people.

  

  A few days ago, the topic "Why are young people willing to spend thousands of dollars to buy a’ pinch’" rushed to Weibo hot search. In fact, "Pinch" is a kind of slow-rebound decompression toy, made of soft silicone materials, which highly restores the delicious and attractive food shape. It is loved by many young consumers because of its beauty and fun, and its price ranges from several yuan to thousands of yuan.

  

  According to the industry, "pinching" can release the pressure and anxiety accumulated by young people in their work, study or daily life. Among them, the limited edition or specially designed "pinching" is hyped due to scarcity, resulting in abnormally high prices. At the same time, the "pinching" industry standards and regulations urgently need the relevant departments to clearly specify the materials, safety performance and labeling requirements of the products, so as to avoid endangering the health of consumers.

  

  Pinch lets people release pressure and adjust their mood.

  

  "Pineapple bags, rice balls, doughnuts, strawberry cakes, fried dough sticks" … Li Jingwen, a white-collar worker in Beijing, showed his trophy about "pinching" to the reporter of China City News. These "pinching" shapes are so lifelike and lovely that people can’t help but want to pinch them. There are many young people like Li Jingwen who have been "pinched".

  

  In fact, in addition to the above-mentioned baked cakes and other food shapes, there are also "pinched" shapes of plants and animals on the market, most of which are made of silica gel, which will not melt or harden, and have strong plasticity, and can be roughly divided into three categories: water feeling, cement feeling and mud feeling. Among them, the water is the lightest and softest, it has no resistance when pinched, and it rebounds the fastest; The cement feels slightly with plasticine feel, and the rebound speed is moderate; Mud feels like squeezing plasticine, and its rebound is the slowest.

  

  According to the data of Tmall New Life Research Institute, in 2022, the overall growth rate of decompression toys in Taobao Tmall was nearly 40%; By 2023, "pinching" has become one of the fast-growing toy categories in Taobao 2023.

  

  "The first time I came into contact with’ Pinpinch’ was when I brushed relevant posts in Little Red Book at the beginning of this year. I found them cute and found them very interesting. Plus, I usually like small craft products, and I went to into the pit after I got to know them a little." Li Jingwen told reporters that when you pinch this kind of slow-rebound toy, you will feel very calm in your heart. While playing "pinching", you can also make it faster to think and reduce anxiety while working or studying, which can achieve the effect of venting emotions or relieving stress for her.

  

  There is also a saying circulating in the "pinching" circle: "When you pinch this toy, you will never forget the feel." As a decompression toy, "kneading" can make people feel relaxed and happy under the simple kneading or squeezing action. Zhang Yue, chairman of Aoyou International, said in an interview with China City News that in the fast-paced life, many people are facing the pressure of work and life, and "pinching" provides a convenient and brand-new entertainment way, so that people can release pressure and adjust their mood anytime and anywhere.

  

  Why are all kinds of "pinching" different in value?

  

  The strong purchasing demand of young people has also stimulated the "pinching" market. In addition to being able to buy "pinch" in Jiumu Sundry Club, The Green Party, famous products and other stores, online platforms such as Taobao, Xiaohongshu and Xianyu also have a wide variety of "pinch" on sale, most of which are priced between several yuan and hundreds of yuan.

  

  However, there are some exceptions, such as Zulala Pinch, which is very popular in the circle. In particular, a blogger in Xiaohongshu has exposed an out-of-box video of Zulala Pinch worth 15,000 yuan, of which two Zulala Pinch were filmed at a price of 2,900 yuan, so some netizens joked that Zulala Pinch is Hermes in Pinch Circle.

  

  Li Jingwen told reporters that her purchasing channels are generally small red book shops, Taobao shops and micro-shops, and occasionally from the live broadcast room, with unit prices ranging from 10 yuan to 60 yuan. Under normal circumstances, the larger the volume, the higher the customer unit price, and the pricing of different stores is also different. "At present, I have not bought a’ pinch’ with a unit price of more than 100 yuan." Li Jingwen said.

  

  In fact, most of the "pinching" of high-priced auctions on second-hand platforms come from hand-made shops in online celebrity. "This reflects the imbalance between supply and demand in the market and the drive of collecting and showing off." Yu Fenghui, a special researcher of China Financial Think Tank, analyzed in an interview with the reporter of China City News. On the one hand, some limited edition or specially designed "pinching" became popular due to scarcity, and the hype similar to tide play made their value surpass the toys themselves and become collectibles; On the other hand, some young consumers are willing to pay a high price for this, in addition to the actual decompression needs, but also because of its role as social capital, that is, by having a unique or expensive "pinch", they can show their personality and taste among their peers and meet the needs of self-expression and social comparison.

  

  Emotional value business is popular

  

  This young people are troubled by small emotions and pay for them.

  

  According to the data released by the survey results of China Modern Consumption Development Index in 2023, the proportion of consumers who think that "pleasing oneself" is more important has risen sharply, reaching 47.8%, an increase of 16.8% compared with 2022. According to the data of China Consumption Trend Survey in 2024, 64% of consumers pay more attention to spiritual consumption, and young consumers pay more attention to spiritual consumption. Consumers pay more attention to their own small world and pursue a sense of gain, value and significance. Rational consumption and emotional life will become the fundamentals of consumption.

  

  Behind the popularity of "pinching" the whole network and the price of thousands of yuan, many people have found that selling emotional value seems to be gradually becoming a business. For example, recently, a product named "hydroponic banana" continued to sell well on the e-commerce platform. In the past month, more than 10,000 people bought a number of similar products, most of which sold thousands. According to reports, this kind of hydroponic banana is different from the general foliage planting, and it has the characteristics of "viewing+eating", and it is easy to feed. Just put it in a vase full of water and wait for about a week to mature. For migrant workers who don’t have much energy to take care of it, the cost is extremely low and more worry-free.

  

  Besides hydroponic bananas, other "emotional" fruits are also favored by consumers. For example, on the shopping platform, 20 yuan can buy a "fresh-cut pineapple" and a pot of tomato seedlings for 30 yuan, while hydroponic strawberries, hydroponic bergamot and other categories range from 20 yuan to 100 yuan.

  

  Is the emotional value business really so "profitable"

  

  In Yu Fenghui’s view, the business of selling emotional value is profitable to a certain extent. He believes that with the growth of social psychological demand, people are more and more willing to pay for products and services that can bring psychological comfort and emotional satisfaction. The commercial logic of emotional value lies in that it captures the pain point of modern people’s lack of emotion, and creates an emotional resonance through product design, marketing strategy and brand story, thus transforming it into consumers’ purchase intention. However, this kind of market also has volatility and uncertainty, which requires continuous innovation and precise positioning to continuously attract consumers.

  

  In this regard, Zhang Yue holds different views. "Selling emotional value has indeed become a business, especially among young people, but it is not always easy to make money." Zhang Yue said that in addition to "pinching" such decompression toys, other emotional value products, such as psychological counseling services and emotional healing books, also need to be attractive enough to attract consumers. In addition, product quality, brand reputation and service quality are also important factors that affect whether this business can make money.

  

  Zhang Yue’s worry is not unreasonable. Some bloggers revealed: "I bought a bunch of’ pinching’, and the flavor was very strong. I simply measured it with a formaldehyde instrument and directly exceeded the standard. These two days are not only crazy acne, but also conjunctivitis. I don’t know if it is related to’ pinching’. "

  

  It is reported that Guangzhou Consumer Council has published the comparative test results of 37 decompression toys. The test results show that the product has some quality problems and potential safety hazards, such as excessive plasticizer, excessive release of volatile organic compounds and xylene, too many colonies and too loud noise.

  

  At present, there are many sales categories and channels of "pinching", but few well-known domestic manufacturers enter the market, and most of them are handmade by individuals. Therefore, many people in the industry call for the industry standards and regulations of slow-rebound decompression toys to be clearly defined by relevant departments in terms of material specifications, safety performance, labeling requirements, etc., so as to effectively and pertinently supervise and ensure that products meet human health standards, standardize market order, and safeguard the legitimate rights and interests of consumers.

  

  In addition, Yu Fenghui also suggested that excessive market speculation may cause a price bubble, which will lead consumers to blindly follow suit and eventually cause economic losses. At the same time, over-reliance on "emotional economy" may ignore the practicality and durability of the product itself, which is not conducive to the healthy development of the industry in the long run. Moreover, the best-selling of "pinching" may also aggravate the consumerism tendency of young people, and excessive consumption may have a negative impact on personal financial situation and mental health.
