Yang Chengfu
Yang Chengfu developed his own shortened "large frame" version of the Yang long Form, in order to make it easier to teach to modern students who are busy with modern life. Now the most popular long t'ai chi form in the world, the classic Yang Chengfu form retains the health and self-defense benefits of the original 300-movement sequence in only 150 movements, most commonly divided by teachers today into 85, 88, 103, or 108 "postures" or stopping points.
