Unkempt math wizard has formula for fame

Holding a big bottle of water and a bag of steamed buns, and with uncombed hair and a slightly awkward way of speaking, Wei Dongyi does not seem like a typical university teacher.

Wei, an assistant professor at Peking University's School of Mathematical Sciences, recently became an online sensation after netizens found the somewhat shy and unsophisticated man has an extraordinary talent for mathematics.

In a viral video, Wei was asked to give encouragement to high school graduates who were taking the national college entrance exam, or gaokao. He simply replied: "Welcome to Peking University. I don't know what else to say."
