The Wooden Dummy is regarded as the secret skill in Wing Chun, but yet it is not. Those movements are actually based on the combination of the techniques of Siu Nim Tau, Chum Kiu and Biu Gee. The purpose of the Wooden Dummy is to practice the theories and application of movements from the three forms as well as angles of attack up to a person’s limit which one cannot apply on a real person, e.g. practicing the cohesive power. It also allows time for self-correction on any weak points which could not be easy to adjust when under pressure. On the other hand, one can also use the dummy as the opponent to invent attack and defense techniques.
