I have expirience in HAPKIDO AND CHIN-NA(Chinese Grappling). U guys would be surprised on how similar it is to every other grappling art.I guess the main difference is that CHINNA is more of an INTERNAL grappling art... U'll see chin-na in art like TAICHI, BAGUA, XING-YI if tuaght properly and for real...
