Also they have shaui jaiou and chin na which is their version of grappling. Kung fu gets a bad rep. But it's the offspring of yoga and yoga is now very accepted in modern times. Who knows maybe there is some mercenary Tao level kung fu guy out there but not fighting mma. It's no joke. It's very good way to develop a healthy strong body.
