Recently, a math teacher from Peking University has become popular on the Internet. In a video, he introduced himself as a student who graduated from Peking University's School of Mathematical Sciences and a gold medalist（金牌获得者）in the International Mathematical Olympiad.

Netizens immediately found that this was the celebrated assistant professor in Peking University — Wei Dongyi. He is known as "Chen Jingrun No. 2" because he is a mathematical genius.

Wei Dongyi was born in Shandong Province in 1991. He showed great talent in mathematics from a very young age. When Wei was a student at High School Attached to Shandong Normal University, he joined the school's Olympiad training team. Then he took part in the International Mathematical Olympiad training. Because of the wonderful experiences, he fell in love with math and went on to win many first place prizes.

In 2008 and 2009, his amazing performances at the 49^th International Mathematical Olympiad and the 50^th International Mathematical Olympiad made him famous around the world. Wei got two gold medals with full marks. After that, Wei studied at Peking University for four years. Then he got his master's degree and PhD in only three and a half years. In 2019, Wei completed his post doctoral work and became an assistant professor of the university. He still has a love for math and enjoys a simple life. Hearing of his experience, many students were excited and showed their great respect for him.

To make sure of Wei's peaceful life, the university called for reducing attention on Wei. "We hope that people who care about this great teacher will join us in creating an environment for young students to focus on research," the university wrote.
