Chin Na employs techniques of locking, seizing, grabbing, breaking, ripping, and tearing. There are various schools of Chin Na, each with its own small nuances. In modern Kung Fu styles, Chin Na does not feature in its entirety due one simple reason: clothing. Once fancy clothing was regarding as “smart” and society started to frown upon fighting, grappling was seen as “ungentlemanly”. So many of the grappling techniques were discarded not simply not taught and practiced. However, several of the techniques were used to restrain, arrest and nullify opponents (with as little tearing of the clothes as possible). Traditional Chinese Chin Na is a brutal version of modern Japanese Aikijutsu. The objective is to completely nullify your opponent so that he/she does not attack again. In the past this meant, breaks, dislocations, rip and tear, and even kill.
