Chi Sao

'Chi Sao (黐手 literally, "sticky arm") is a Wing Chun term for the principle, and drills based on the principle, of "sticking to" your opponent by maintaining contact with his arms with your own, thereby enabling you to sense changes in pressure and momentum and counter your opponent's movements. Chi Sao is very similar to the hubud-lobud drills of Kali, and is related to the push-hands drills of T'ai Chi Ch'üan. Chi sao is also taught in the Jeet Kune Do traditions, and uses modified versions of some of the component techniques such as the bon sao and jut sao.
