A Chinese genius mathematician lives on 300 yuan a month on principle (7 photos)

11 June 2025

There are still Perelmans in China. More precisely, his name is Wei Dunyi, and he is a Chinese child prodigy and genius of mathematics who does not need money, his annual income is 600,000 yuan.





Who is Wei Dongyi



Yes, the genius has no teeth, which makes him look very unpresentable

He is 33 years old and hails from Shandong Province in eastern China. At the age of 18, he even formulated a system of “Wei Dongyi inequality” that elegantly solves fluid mechanics problems in a way that surpasses standard solutions. He is an associate professor in the mathematics department at the esteemed Peking University. Despite his outstanding achievements in science, Wei prefers a life focused on research and teaching.





He joined social media in the hopes of sharing mathematical formulas, o. naive young man

But on June 4, Wei uploaded his introduction video to Douyin, one of China's most popular short video platforms. The four-second self-introduction quickly went viral, racking up more than 13 million likes. In just five days, Wei had amassed 23 million followers on Douyin. His exceptionally simple and austere lifestyle has captivated social media users, who affectionately dubbed him "God Wei." Wei first gained national attention in 2021, when he was shown in a street interview wearing rags and holding a water bottle and a plastic bag containing three steamed buns.



This is what he looked like in 2021, with his teeth back then

In the video, Wei is smiling, and eagle-eyed viewers quickly noticed that he is missing his front teeth. Everyone was shocked that the math star could be so thin, weak, and looking emaciated, not to mention his teeth. Wei's cousin revealed that he suffers from gum disease and has undergone treatment twice in the past year. He has also been a vegetarian since childhood, only allowing himself milk and eggs.



At least he is socialized enough to teach, which is good

The mathematician himself said that it was his family who told him to start communicating on social networks, as this should help him socialize. Seeing the deplorable state of the teacher, many were horrified - does he get paid so little? Or does his family not care about him at all and take away his salary?! In fact, this is his path - to reject as much materialism as possible, he is more interested in numbers and formulas.

His annual income is over 600,000 yuan. But it is his principled choice to spend less than 300 yuan a month in Beijing. Which sounds like insane begging. And at the same time, he also refused a prize of one million yuan from the prestigious Chinese Damo Academy Young Fellow Award. Which is what makes him related to our Perelman. It turns out that these mathematical geniuses are in many ways the same - not of this world and not very good at taking care of themselves.



No, well, in principle, you can live on 300, if you EAT MEAT

The only difference is that Wei's family has already been pecked to death, considering it their fault and responsibility. After all, "family guilt" is strong in China, not like in our country.
