Chin Na

Qin Na () is the set of joint lock techniques used in the Chinese martial arts to control or lock an opponent's joints or muscles/tendons so they cannot move, thus neutralizing the opponent's fighting ability. ''Qin Na Shu'' ( meaning "technique") literally translates as ''lock catch technique''. Some schools simply use the word ''na'' ("hold") to describe the techniques. Qinna features both standing and ground-based grappling techniques.

Some Chinese martial arts instructors focus more on their ''Qin Na'' techniques than others. This is one of the many reasons why the ''qinna'' of one school may differ from that of another. All martial arts contain ''qinna'' techniques in some degree. The southern Chinese martial arts have more developed ''Qin Na'' techniques than northern Chinese martial systems. The southern martial arts have much more prevalent reliance on hand techniques which causes the practitioner to be in closer range to their opponent. There are over 700 ''Qin Na'' traditional techniques found in all martial arts. In the Non-Temple White Crane style there are 150-200 ''qinna'' techniques alone. Along with Fujian White Crane, styles such as Northern Eagle Claw (Ying Jow Pai) and Tiger Claw (Fu Jow Pai) have ''qinna'' as their martial focus and tend to rely on these advanced techniques.

There is no universally accepted systemized form of ''Qin Na''. Instead, each school varies depending on the instructor's training and/or personal preference of focus. Provided by Wikipedia
