Footage of an MMA fighter knocking out a Tai Chi master in just 20 seconds in China.

The video, filmed in Chengdu, Sichuan Province on April 27, shows mixed martial artist, Xu Xiaodong, annihilating the self-proclaimed Tai Chi master, Wei Lei, just 20 seconds into the bout.

In order to prove that Tai Chi and other traditional forms of Chinese martial arts were no longer relevant, Xu challenged Wei around half a year ago.
