won the Olympiad gold medal and became a short video blogger; after studying for a postdoctoral degree in the Department of Chemical Engineering at Tsinghua University, Yoyo can still play a national runner-up. Do you think he is just a top student, but he is still a hidden joke player.
Behind so many shining tags is a pretty boy with a small body. His name is Shi Jiaxin. He is a "post-95" from Huludao, Liaoning. Shi Jiaxin has a well-known name for more people - "Tsinghua Doctor Wang and Mr. Shi", which is the nickname of his TikTok account with 750,000 fans.

Today, Shi Jiaxin has become one of many knowledge bloggers in TikTok. In his loyal fans' opinion, he is not only a senior at Tsinghua who teaches learning methods, but also a popular science doctor who brings ultra-high-definition chemistry experiments to Douyin, but also a "chemistry poet" who can tell awkward knowledge interesting and romantic.
How to develop the academic master of "Whatever you do"
I have been an efficient and conscious child since I was a child
I have never opened my schoolbag before when I went home in the second year of high school
"I am more serious and have a bit of an old cadre style." 27-year-old Shi Jiaxin said that he has not been the naughty child since he was a child. Although he also plays when he should play, he doesn't like to make trouble.
Shi Jiaxin is a conscious person and is very efficient in doing things. He said that before the second semester of his second year of high school, he would finish his homework at school. The evening self-study get out of class was over at 8:10, and I basically never opened my schoolbag when I got home. However, he believes that no one is born to love studying, and he just doesn’t hate studying. He finishes his homework quickly at school, so that he can relax when he goes home.

Of course, there are many students who use their time to do their homework like Shi Jiaxin, but with the volume of high school, it is still very challenging to complete all of them in school. Speaking of his "small tricks", Shi Jiaxin said: "I don't like writing steps, so others basically can't understand my exercise book . I won't write step by step like the exam, but I will write the key points and calculate the necessary numbers."
In the second year of high school, Shi Jiaxin embarked on the road of preparing for the Chemistry Olympiad. At that time, there was only half a year before the exam, and it was one of his little students who tried the competition. At this time, efficient habits helped him again. Although he prepared for the battle late, because he could complete his homework at school, he could use all the time after he returned home to prepare for the competition. "At that time, it was not said that I had to pass the exam, but it just increased the probability of getting into a good school. I was not biased towards subjects and still reviewed the college entrance examination normally during the day." In the end, Shi Jiaxin won the gold medal in the National Chemistry Olympiad and obtained the Tsinghua University qualification for admission.
has strong inductive and summary abilities
is willing to spend time analyzing his own problems and assessing vulnerabilities
Speaking of his greatest strengths, Shi Jiaxin said modestly that it may be because he has strong inductive and summary abilities. "It is actually very tiring to spend time analyzing your own problems. Evaluating loopholes is actually very tiring, but if you want to become strong, you have to constantly evaluate and summarize yourself. My self-drive is quite strong."
"Many people may just listen to some lessons and do some questions by themselves, but don't think about how to solve their problems. If you don't know what you don't know, you will never know what you don't know."

"It's like cooking. It's hard to cook at once. You have to analyze the reasons, how can you make it better? You can't just go through it casually. Some children say that they haven't learned mathematics well, but they haven't learned it well. Which ones do they don't know what they do. I don’t know the knowledge point, which question type, and which module have questions. If I can’t answer these, it means I haven’t even achieved the most basic assessment myself.”
He also said: “In fact, discovering my own problems is the most difficult thing, because it is equivalent to asking you to admit your mistakes.”
Parents never arrange for me
When others take the double hundred exam, I scored more than 80 points, my parents won’t be angry. When talking about their parents, Shi Jiaxin’s first thought of the word “openness”. He said that as long as there are no principled problems, parents will not care too much. His grades were not outstanding in elementary school. When others took the double hundred exam, he sometimes scored more than 80 points, but his parents would not get angry or force himself to study.
. Regarding making choices, Shi Jiaxin said that most of the time, parents just give some advice indirectly. During his days at Tsinghua University, Shi Jiaxin has been engaged in polymer-related study and research. His undergraduate major is polymer science and engineering, and his doctoral and postdoctoral are materials science and engineering. "I basically make decisions when choosing a major and school, and my parents won't interfere too much. They are not parents with strong control." Regarding their future careers, Shi Jiaxin also said that their parents never said what they hoped to do in the future.

Jiaxin looked back when she grew up and thought, perhaps her parents also understood that everyone's own limitations, so they would not impose their own thoughts on their children. This also made Jiaxin very independent since childhood.
People who study well never only learn
books, movies and variety shows, badminton shuttlecock drums,
When many people complain about the inconsistency of science and engineering men, Shi Jiaxin brought chemistry to many people with his "romantic physique", which is inseparable from his extensive reading and wide hobbies.
On those nights when the homework is completed early in the student stage, Shi Jiaxin has a lot of time to read. He said that he reads all kinds of books, popular science, history, literary classics... No matter whether it is humanities or social sciences, he will dabble in books that can be placed in a bookstore. Usually, he also watches movies and variety shows, but he watches TV series relatively less because it is too long and does not have that much time.

In addition to reading books, Shi Jiaxin can also play badminton and shuttlecock without any worries, and occasionally play drums. But his favorite is Yo-Yo, and he also played the runner-up in the national competition. It is said that the title of "Mr. Shi" was given to him by his friend when he participated in the YouYoHi ball game in high school. He said he likes yo-yo because it is unrestricted and can be played anytime and anywhere, and can always create new ways of playing, not boring and feel free.
The science and engineering man’s "three powerful tools" for Douyin
Do the most romantic chemistry experiment
Let fans use the spirit of CP to chase science popularization
Speaking of the romance of science students, you must be slightly shocked by such a picture

The strong contrast between extreme romance and cold science can always make people shout - this romance is too advanced! And in Shi Jiaxin's popular science short video, this little romance of science students can be seen everywhere.


In the experiment of injecting potassium permanganate into hydrogen peroxide , Shi Jiaxin described the encounter of the two in this way - "One gives all of it, the other is indifferent, and for a moment it turns red, and it's just a moment." When demonstrating the experiment of precipitating crystallization of the unsaturated solution of sodium acetate , the heart-wrenching copy was staged again - "Our feelings are like water and sodium acetate. Even if we hug them warmly, they will freeze in the end", which tortured the fans.


Speaking of Shi Jiaxin's earliest video of becoming famous, it was a brilliant "golden rain" he brought down. He dissolved lead acetate , added potassium iodide solution, heated it, took out the supernatant, then cooled it, and finally brought the glittering "golden raindrops" to netizens. A fan jokingly said in his comment section: "Touched! Finally, I don't have to watch the chemistry experiments of image quality in the 1990s!"


Shi Jiaxin said that in fact, the experiments he needs to come into contact with in daily life are much more complicated than these, but the most important thing in popular science is that people can understand it. Romantic words, beautiful pictures, and exciting music can make cold chemical knowledge more sensible. Once people have psychological immersion, it will not be that difficult to keep looking.
The mutual achievement of romantic bloggers and talented fans
If Shi Jiaxin brought the slightly boring chemical aesthetic to more people, then the fans left a message on Erchuang in his comment section, which made each of his short videos form a magical "romantic closed loop".
In the experiment of injecting potassium permanganate into hydrogen peroxide, Shi Jiaxin made an interpretation of "one gives all its own things, the other is indifferent". The comment section was not to be outdone and gave a romantic sublimation of "You only know that potassium permanganate has faded, but you don't know that the hydrogen permanganate has actually been oxidized. It is no longer hydrogen peroxide. You think it has not changed anything, but because of you, it is no longer it."

Shi Jiaxin likes to read these interesting interpretations in the Douyin comment section. In his eyes, natural science, or many things in nature, are very similar to some human behaviors themselves. "Many people feel headaches when they hear chemistry, but through videos, pictures and stories, they feel 'hey, this thing is quite interesting', which reflects the meaning of doing this."
was ready to seize the initiative
0 Shi Jiaxin can stand out among the thousands of self-media bloggers, and keenly seize the initiative is indispensable.

He said that when he first posted experimental videos on Douyin, there was still very little content of the same type on the Internet. It is not Shi Jiaxin's unintentional way to become a science blogger. From the beginning of establishing an account, he embeds the title of "Dr. Tsinghua University" into his nickname, from sharing learning methods at the beginning, bringing fans to travel to Tsinghua University, and even posting some videos of playing Yo-yo when they have nothing to do, to gradually determining the track of popular science and sharing beautiful chemical experiments... Shi Jiaxin found his own style from simple attempts, and walked out of his own popular science map with a seemingly calm pace.


"No ambition" down-to-earth
has no ambitious goals, but does everything in front of you well
can learn well and play well. Many people lament that Shi Jiaxin is really a "child of other people's family." However, Shi Jiaxin said that he was not very smart, nor did he have the so-called ultimate goal, or the idol he wanted to pursue. Many times, I just follow the rhythm and walk step by step.
When asked if his popular science videos became popular for the first time four years ago, Shi Jiaxin said that they did not; and when the reporter asked if the video would be disappointed if it was not popular, he also said, "That's nothing, it's just a question of speed and slowness." '"
Although the identity of a popular science blogger made Shi Jiaxin famous, that was not his main business. He said that a popular science blogger may only account for 5% of his identity attributes. In addition to the Douyin blogger, he is also a postdoctoral fellow at Tsinghua University who focuses on scientific research and is also an entrepreneur.
has no ambitious goals, but does everything in front of him well. This may be the "no ambition" exclusive to Shi Jiaxin. Looking up at the starry sky is important, but down-to-earth is always the only ladder to the starry sky.
