You don't see any UFC or Pride fighters using any techniques from Chinese arts. And there's a reason why, it's because they don't even begin to compare to what they already use such as Muay Thai, boxing, wrestling, and Brazilian jiu jitsu. I've never seen Wing Chun used in any fighting tournaments and succeed. Even Bruce Lee gave up on it later in his life because it was too rigid and not practical for real life. I've seen clips of Wing Chun guys getting rocked by Thai fighters, boxers, and grapplers. Sanda/San Shou is a half assed lame attempt creation by the chinese to compensate for their losses against Muay Thai fighters for over a decade. Since the late 70's, Chinese martial artists got their * handed to them by Thai boxers. So they came up with Sanda. Sanda is not a true chinese art. It really does not have any moves that are uniquely chinese. Their moves are borrowed from boxing, wrestling, and some tae kwon do.
