There are more than 2 classes... This is the soft kind of Tai Ji
from Cheng Man Ching. Dun rely on 'stiff strong strokes'. For every
force there is a counterforce. Violence, even well intentioned,
always rebounds upon oneself. If u want to given everything, give
everything up. Only in being lived by the Tao can u be truly
yourself. Learn Tai Ji Chuan to be more healthy and be efficient in
self-defence. Please visit http://taiji15.tripod.com for more info...
