italian_guy, Hello, I study Yang Style Tai Chi Chuan, I have yet to see Chen Style. But I just wanted to say That I am confused by Jerry's statements. Let me clarify myself as best I can. I study Yang Style that originated from Yang Lu-Chan (1799-1872) a native of Hebei province. I am currently working on the 24-movement form. All the moves have practial martial applications, if a practitioner does not know these applications, it's only because they were taught by someone who was not aware either. The body must be connected and the applications understood, if not, a pearson may as well make-up their own moves. These are some of the differences between real and imatation. So, I have to disagree with Jerry, only because what I have learn and train in is 100% combat Tai Chi. I will check out Chen style , I'm curious. Thanks italian_guy, Jerry please do some more research, because I think there is more there than you are aware of. I am learning as I say 24-movement and I have noticed some. Needle at the sea bottom- wristlock takedown, Rollback-shoulder lock, Raise hands-lifting elbow lock, other than those the rest are blocks, strikes, kicks, evasive, defensive moves.
