I told you yesterday, I have started my summer vacation. He was so happy, he jumped up and down. Thinking about it, seeing it as I was when I was a kid, but hearing that the teacher was busy, sick, and on vacation, the students were more busy playing than studying. Particularly for Summer is a very long excitement, because it brings so many plans, plans and games ahead. “Dragonfly bites navel and knows how to swim” – so many children have been tricked into this. Photo: Thanh Nguyen. I still remember, when I was a kid, Summer was an opportunity for a lot of “starts” at first. From the first time going to see crabs (crab hooks), fishing for frogs, catching fish, slapping fish… to children’s activities: exercising and kicking football early. As for the games, there are many, from shotguns, passing, marble shooting, fighting, fighting, umbrellas… Part of a memory. Photo: Thanh Nguyen. In those days, the field after the harvest was a big stage for the country kids. In my house, there are no buffaloes or cows, but because I crave the country atmosphere with many games and strange dishes, I often follow my brothers and friends in the neighborhood. After the harvest, the countryside is temporarily empty. After the harvest, all the grasshoppers, frogs, and especially mice were gathered in the fields of elephant grass. These are the fields converted by dairy households, from rice to grass for food. At that time, during the day, they fished frogs, at night they looked at locusts and caught birds. But the most fun is still the sessions to dig mice. Usually groups of several or three children will bring a bucket, basket or bag, a spade and a dog. Dogs have the ability to sniff out and catch mice very well, buckets can make water with simple burrows. Field after harvest. Photo: Thanh Nguyen. Rats this season are fat because they are full after a rice season. After catching, bring back, peel off the skin, cut off the head and legs, just take the meat of the body and thighs and then marinate it and bake it. In the summer, every child does not have a small cage. In the countryside, usually every house has a few areca trees. In the summer, those who are good at climbing will be responsible for finding the nests of young birds and sharing them with each other. The young sparrows are hungry, full of shit, their mouths are always wide open to eat when they see people. The food is cold rice, but the most common is grasshoppers, so if you don’t go to the field every day, you have to run to green vegetables (5% field area for households to grow vegetables) to catch some locusts to bring back. make bird food. Draw sketch. Photo: Thanh Nguyen. I remember, when I was a child raising birds, my parents taught me to give the birds light salt water to drink, so I got used to it, even if the birds fly away when they grow up, they still have to come back to drink water. That pure joy keeps growing, from the time the bird is young until the bird is full of feathers, flying and growing. I remember back in the 90s, raising snails was fashionable among the kids. In the new wave of that movement, I had to ask my parents for money to buy it. Where 1,000 VND/pair of small snails, or a few thousand a tool snail, bring back and drop into a crock pot or fish tank to raise. Day by day, go to pick duckweed, water hyacinth, or gather all kinds of leaves for snails to eat. When the snail lays, each pink ovary as big as a strawberry will gradually turn white, it’s time to take out toothpicks to get the baby snails. Raising snails and birds is also meticulous and takes time, but fun. Then, only later, did I know that the “toy” once was a terrible thing to destroy the rice fields. The imprint of the game in childhood has not ended many times when returning home many times, on ditches or bamboo poles in ponds and lakes, still full of eggs of this agricultural “rebellious” group. The nest of golden snail eggs is associated with the childhood of many rural children. Photo: Thanh Nguyen. Summer brings showers. After such meals, the pond is filled with the sound of frogs, hawks, and owls. Me and my friends carried fishing rods. Frogs with nuggets (a baby frog about the size of a big toe) are brought back to be raised somewhere in the garden or pond. Big frogs have to buy long bamboo sticks and melon flowers to lure. If there is a frog, there will be a pot of melon soup. In those days, finding a frog with 3 fingers was already very big, unlike now, frogs raised as big as fists, why eat frivolously. Summer is coming, for the children of the countryside, it is also the season of petty theft, because this is the most fruitful season. From sugarcane, guava, alligator, toad, citrus, mango, queo, papaya, etc. The day before yesterday, when I returned to my hometown, my friend also read aloud the “directory” of sweet and fragrant flowers, who had what tree, what delicious fruit. , it’s by heart. See, the taste of stolen fruit is so delicious and attractive that, after more than 20 years, people still remember it. In those days, the children often looked at Gac fruit, any house that had a ripe gac fruit, even if it was new, but did not cut it quickly, it was stolen by the children, just to get the seeds to play. As for the other fruits, they are extremely different, each day they change a dish. In those days, the booty was often carried by the children to the bunker on the embankment to raid. I don’t know how many moonlit mornings, the village dike was filled with laughter, eating and talking like that. And the most interesting thing, that day, the matter of stealing fruit was rarely concerned by parents, it was an accepted thing. Maybe it’s just a few reprimands from time to time, because everyone seems to implicitly admit that it’s a part of everyone’s childhood.

A heart cell organ that can beat like a real heart. Photo: livescience According to sciencemag.org, this mini organ (cell organelle) mimics the real heart of a 25-day-old human embryo and could help solve many mysteries, such as why children’s hearts don’t have scars. after having a heart attack. Not involved in the new study, but Zhen Ma, a cardiac organelle development bioengineer at Syracuse University, says it’s a great study, and the experiment is important in understanding Congenital heart defects and human heart formation. This process has so far relied solely on animal models. Although other mini-organs such as the brain, intestines, and liver have been grown in the lab for more than a decade, the heart cell organ presents a more challenging challenge for scientists.
The first cardiac organoids were created from mouse heart cells. They may beat on a lab plate, but they look like a bunch of heart cells, not a real heart. According to Aitor Aguirre, a stem cell biologist at Michigan State University, the cardiac organelle needs to function. With the heart, one wants the heart cell organ to have chambers and function to beat in rhythm. Watch a video of a mini heart beating in the lab (source: Sciencemag.org): To create an embryonic-like self-organizing heart cell organelle, the authors of the new study programmed human pluripotent stem cells (cells that have the ability to develop into any type of tissue). which) for this cell to turn into other types of heart cells. They wanted to create three layers of cells in the wall of the chambers of the heart, one of the first developing parts of the heart. Next, they embedded these stem cells in different concentrations of growth-promoting nutrients. They tried until they found a recipe to get these stem cells to form tissue in the correct order and shape in the embryo. After a week of development, the cardiac organelle was structurally equivalent to the heart of a 25-day-old embryo. At this stage, the heart has only one chamber, which will later be the left ventricle of the mature heart. Cardiac organelles are only about 2mm in diameter and have the typical major cell types in this stage of development: myocytes, epithelial cells, fibroblasts, and the epicardium. They also have a clear chamber that beats at a rate of 60-100 beats per minute, similar to the heart rate of embryos of the same age. Lead study author Sasha Mendjan, a stem cell biologist at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences, said: “When I first saw it, I was surprised that these chambers had self-forming. What’s amazing is that you see right away whether this experiment works and if this organelle is working, because it has a pulse.” Scientists were able to study heart formation in unprecedented detail. Photo: livescience The mini-heart has so far been more than three months old in the lab and will help scientists monitor the heart’s development in unprecedented detail. They can know the source of heart diseases such as congenital heart defects in children and heart cell death after a heart attack. Mendjan and his colleagues also frozen organelles to test their response to injury. They found that cardiac fibroblasts, a type of cell responsible for maintaining tissue structure, travel to the site of damage to repair dead cells, as happens in children who have had heart attacks. Scientists have long wondered why children’s hearts can regenerate after being damaged without scarring, unlike adults. Mr. Aguirre said the next step would be to connect this organ of beating heart cells to a network of blood vessels and test its ability to pump blood. Mendjan’s team intends to find a way to modify the nutrient solution to produce a four-chambered heart cell organ. With this innovative heart cell organ, researchers were able to learn more about heart problems that can arise when the walls of the heart’s chambers begin to form. Meanwhile, Mr. Ma said that growing a more mature heart cell organ with all four chambers and structure is a matter of the future. He thinks this will take a decade to materialize.

For a long time, teachers, student resources, and teaching and research capabilities have been called the troika of online education, and excellent talents are the core of doing business well. Previously, Dali Education said it would recruit more than 10,000 people. Chen Lin, CEO of Vigorous Education, clearly stated, “In the next three years, Bytedance will continue to invest heavily, regardless of profitability and cost.”

A recent change in the personnel responsible for the education business has attracted attention. According to “LatePost” reports, key projects including children’s enlightenment product Guagualong, primary and secondary school online school Qingbei online school, adult language product open language English, hardware business vigorous intelligence, etc., have had at least one business in the past year The line leader has been replaced, and 100 people have left for some projects.

△The changes in the personnel responsible for the education business

From doing education business to forming an overall education brand

Bytedance “vigorously” do education

Zhang Yiming always loves to say: Vigorously creates miracles. Byte has invested heavily in education. The three-pronged approach of incubation investment and acquisition has covered all popular tracks in the education field in less than two years: Enlightenment, K12, adult education, and even hardware research and development. Gua Gua Long, Tang Yuan English, Qingbei Online School…More than 20 education projects in hand, to create a matrix of online and offline products.

In May 2018, ByteDance made its first effort in the education industry, launching GOGOKID, the first children’s English product, which was benchmarked against VIPKID. In September of the same year, Bytedance acquired Ai Xue, the To B business of Xuebajun. In December, it bought the adult education product Kaiyan English.

In May 2019, ByteDance acquired Qingbei Online School, which focuses on the K12 track, and successfully entered the field of large classes. In November, it arranged the business of entering the school and acquired the big data of Jike.

In March 2020, Guagualong Enlightenment was launched, and the enlightenment business was deployed. In August, it acquired the math and science thinking education product You Pai Yi, and continued to increase quality education.

When Dali Education was established, Bytedance used internal incubation, acquisition, investment and other means to weave a nearly complete educational puzzle, covering English training, K12 subject counseling, knowledge payment, mathematical thinking, and educational information. In the industry chain, To B and To C go hand in hand.

In terms of operation, Byte has burned money very boldly. GoGoKid burned 1 billion, and Guagualong English invested 2 billion in diversion in a year. Qingbei Online School recruited online teachers with an annual salary of 2 million, and there was no ceiling. It is also unambiguous to give resources to people. After suspending the mobile phone business, Zhang Yiming immediately merged the Xinshi laboratory of the hammer technology team into the education hardware team to expand its strength. In Byte’s own words: All in education.

Head of business changed blood

Is it a competitive crisis or a new turning point?

Zhang Yiming’s three most promising industries are AI, automotive, and online education. Today, AI has “Flying Books” and automobiles have “Knowing Car Emperor”, but there have been no successful cases in the education field. Instead, GoGoKid was exploded with a large number of layoffs, aiKid ceased operations, Qingbei Online School founder Liu Yong resigned, and there was a large-scale transfer of branch leaders.

Behind the personnel transfer in the past year, is the industry competition too fierce, or the project requirements are further increased?

Industry competition:

/ / For the online education industry, Bytedance is a bit late

From the perspective of time arrangement, in June 2014, Chen Xiangdong founded GSX; in 2012, Yuanjiao was established; in 2010, Good Future went public in the United States. The industry competition pattern has basically taken shape. Since then, every company that tries to take a share in online education has encountered difficulties. Taking 2020 as an example, 80% of the 103.4 billion yuan that capital has sent to the online education industry went to the top 5 companies, such as the above-mentioned ape tutoring, homework help, and GSX.

In June 2020, “the first unit of online education” New Oriental Online recruited more than 200 fresh graduates in Xi’an to enrich the online education business, but this move suffered a rout. It experienced two layoffs at the end of 2020 and in March this year. More than 200 fresh graduates were almost completely laid off.

/ / Education for laymen also has certain risks

At the end of March, an Internet respondent posted a post on Weibo: A netizen who was certified as a “Tencent Technology (Shenzhen) Co., Ltd. employee” complained on the social platform: “I am leaving soon. Although I am very reluctant, there is really no way. The company is a good company, but Tencent Education is not. I hope that future generations will take warning and don’t educate if you are killed!” A “Beijing Byte Beat Technology Co., Ltd. employee” commented: “You have not come to Byte Education. …I jumped out of Tencent Education. I thought that Tencent’s education pits now… I can only say that pits are not pits or not.” Another “Tencent Tech employee” replied: “I feel that every education is pitted, run away. ”

Although it is only an online topic discussion, it is not difficult to see that even with a huge number of engines, it is equally difficult to cross-bank business. Tang Daosheng, vice president of Tencent, said: “Education is a very complex and professional field, and all our internal forces add up, and it may not be able to subvert all needs.” Education is a slow industry, and the Internet will definitely not subvert the education industry. “But there is no doubt that with the development of technology, education will indeed undergo subtle changes.

Project self-cultivation:

Zhang Yiming has proposed more than once that he wants to run the third product with a DAU of more than 100 million dollars in the education field and turn education into a 100 billion U.S. dollar business, which is larger than Douyin’s scale. It can be seen that byte’s requirements for its education projects are extremely strict.

In ByteDance, the establishment of innovative business projects needs to be reviewed by Zhang Yiming and the project leader, and then analyzed and demonstrated by the business analysis team. All projects need to assess ROI (input-output ratio). If the key project fails to prove its value within a period of time, adjustments will occur.

Do education from “0”, vigorously educate and keep trying “wrong”. I have done many projects vigorously, recruited a lot of people, spent a lot of money, and every time a person in charge is changed, the business direction will be adjusted accordingly. For example, the thinking course under Guagualong has experienced three principals for more than a year. The current principal, Liu Juan, used teaching and research to design experience courses, replacing the predecessor Qianjinchen’s strategic direction of teaching and research guided by products. In addition, vigorously educate because the team expands quickly, and projects and tasks are dismantled layer by layer. Once a team’s project fails, it will be replaced, and it will never be tolerated.

This time, a bold and resolute effort in education, but so far has not yet formed a successful work. In an interview with the media, Chen Lin, the head of Dali Education, said that internal BP has been done for three years. From the perspective of BP in three years, it is not profitable, but he thinks it may be unprofitable for a longer time in the future. He said, “Education is not a track that can be rushed into.”

For educational products, more patience and persistence are required, and a trace of luck is required to find the right method in frequent trial and error correction.

Recently, Luong Thuy Linh continued to “promote” this fashion on Phu Quoc beach. In the photo, Luong Thuy Linh has transformed a scarf into a very sexy “croptop”, just by tying and tying a few steps. “The shirt” is reconstructed from the scarf in an extremely attractive and impressive way. This sexy image has been praised by many netizens. However, appearing below her post, someone even “threatened to hit” Luong Thuy Linh because of this boldness. However, some comments that this seems to be a joke for the queen. This is not the first time, Luong Thuy Linh has transformed the scarves into costumes. Miss Vietnam World used to impress with Hermes brand clothes set. Loyal beauty with an elegant neck shape flaunts her slim shoulders, thin green straps, along with that to reveal a delicate round 1. Most recently, in early March, Luong Thuy Linh shared a series of photos and videos of Phu Quoc travel on her personal page. In the picture, the beauty wears many short dresses, micro-bikini to show off her sexy body. Along with the bikini image, the beauty queen born in 2000 added: “Sorry mom x 10 times”. It is known that her mother does not like her daughter to wear clothes that reveal a lot of skin. Therefore, she apologized for once again doing against her mother’s wishes. => Luong Thuy Linh “causes storms” because of the sharp response in “Who is a millionaire”

This also means that Zhang Yiming can actually enter the 2021 Forbes list of the top 20 richest people in the world, with Tencent’s Ma Huateng, Nongfu Spring’s Zhong Suisuan and the Walton family of Wal-Mart in the United States.

In the 2021 Forbes Global Rich List, US$60 billion is undoubtedly the ticket to enter the TOP20

ByteDance, known for its short video application Douyin and Toutiao, a news aggregation platform, has continued to expand from its core advertising business to e-commerce, online travel, online education and other fields in recent years.

According to people familiar with the matter, this expansion strategy has allowed ByteDance to more than double its revenue in 2020 year-on-year to about 35 billion U.S. dollars, and its operating profit has increased to 7 billion U.S. dollars.

At the same time, because TikTok, the overseas version of TikTok, is facing censorship in the United States and India, Zhang Yiming put more energy on Bytedance’s just-started and fast-growing Chinese business, including games, education, and e-commerce.

There are also many media reports that with the growth of the business scale, the Bytedance Flag is bound to face greater competitive pressure. In this context, Bytedance has begun to consider pushing some of its businesses into the securities exchange market for public offerings. (ipo ).

In March of this year, ByteDance hired former Xiaomi executive Zhou Shouzi as its chief financial officer. In the eyes of the outside world, this “heritor” who helped Xiaomi’s listing will also play a vital role in the final listing of Bytedance.

In February 2021, ByteDance’s direct competitor Kuaishou landed on the Hong Kong stock market and raised US$5.4 billion, becoming the largest listed Internet company after Uber Technology. The competitor’s outstanding achievements have also allowed the capital market to constantly focus on the possible future IPOs of Bytedance.

On the other hand, Ma Rui, a partner of Synaptic Ventures, a venture capital firm, said that Zhang Yiming hopes to establish a long-term and lasting global enterprise, and short-term setbacks in the company’s business will not shake his determination.

According to data from the American research organization CB Insights, in addition to the current market rumored 250 billion US dollars, Bytedance was valued at 180 billion US dollars in the latest round of financing in December last year, compared with only 200 billion US dollars three years ago. Billion US dollars, which reflects the high growth of Bytedance’s valuation.

According to media reports, the valuation of Bytedance is still growing, which for Zhang Yiming undoubtedly represents a greater scale of wealth.
