Chin-Na is the facet of Kung-Fu which involves grappling, joint locks, pressure points, takedowns, and throws for controlling and immobilizing an attacker. These techniques are derived from animal attributes such as the praying mantis hook or eagle claw.

Chin-Na can generally be categorized as:

1."Fen Jin" or "Zhua Jin" (dividing the muscle/tendon, grabbing the muscle/tendon). Fen means "to divide", zhua is "to grab" and jin means "tendon, muscle, sinew". They refer to techniques which tear apart an opponent's muscles or tendons.

2."Cuo Gu" (misplacing the bone). Cuo means "wrong, disorder" and gu means "bone". Cuo Gu therefore refer to techniques which put bones in wrong positions and is usually applied specifically to joints.

3."Bi Qi" (sealing the breath). Bi means "to close, seal or shut" and qi, or more specifically kong qi, meaning "air". "Bi Qi" is the technique of preventing the opponent from inhaling. This differs from mere strangulation in that it may be applied not only to the windpipe directly but also to muscles surrounding the lungs, supposedly to shock the system in to a contraction which impairs breathing.

4."Dian Mai" or "Dian Xue" (sealing the vein/artery or acupressure cavity). Similar to the Cantonese dim mak, these are the technique of sealing or striking blood vessels and chi points.
