Yes Chin Na is awesome and one of the 4 major catagories of Chinese Martial Arts.
Kicking (Ti), Striking (Da), Wrestling (Shuai) and Seize-Controlling (Na).
It is easily incorporated into most any Martial Art Style.
I have read:
Analysis of SHAOLIN CHIN NA
by Dr. Yang, Jwing-Ming
An excellent book an I recommend it to anyone
interested in Chin Na.
Great subject, hope to hear from some others.
