Chum-Kiu by Leung Ting

Chum Kiu is the intermediate set of Wing Tsun kungfu, which should normally be learnt after the Siu-Nim-Tau set. As its name implies, Chum Kiu means the techniques aiming at "seeking the bridge arms of the opponent." In addition, the deeper meaning of Chum Kiu says that the practitioner is to learn how to "look for a bridge" between him and his opponent so he can easily detect the directions of attacks from his opponent.
