Any1 know what kind of tai chi is used in Blood and bone the movie??|||If the push hands was performed in low stances, it is most likely Chen. However Chen also does high stances. The complete list of common Tai Chi styles are Yang, Chen, Wu, Sun, and Wu-Hao. In addition there is Wudang Tai Chi which has a different origin (or so I believe.)|||the 3 most popular styles of taijichuan are Yang, Wu, and chen.. the only bit of the movie I saw was him and his misus doing "push hands" which is used in every style of tai chi.
