The wooden dummy is a man-sized post with three arms and one leg set at strategic angles. Training on the Mook Yan Jong develops the ability to release one’s power smoothly into a stationary object. The wooden dummy form is derived from Siu Lim Tao, Chum Kiu and some Biu Gee.
It is not always possible to practice 100% correct Wing Chun movement with a partner. It is much easier to do so with the wooden dummy, while also generating and releasing strong power. There are many versions of the wooden dummy form. The Wong Shun Leung version has around 147 moves and the Chu Shong Tin version has 108 moves while the Leung Ting version has 116 movements. Clearly, the exact number of moves is not as important as the principles and applications of the wooden dummy forms.
