MMA Thinks Very Little of Some Martial Arts

Martial arts like sumo, Win Chun, Tai Chi, Capoeira, and Kung-Fu have virtually no reputation in MMA. In fact, one Chinese MMA fighter named Xu Xiaodong was so frustrated with claims that eastern martial arts could defeat Western opponents that he set out to prove a so-called master wrong. Xiaodong was able to defeat a Kung-Fu master in 20 seconds flat and a Win Chun master in one minute and 48 seconds. But are self-defense martial arts any better?
