Muk Yan Jong - Wooden Dummy
Put simply the mook jong can be used as an extremely realistic opponent to practice the moves of wing chun on. The way the arms give, and the general springiness of the dummy, replicate the responses of an opponent. A reasonably long form is performed that covers many possible applications of wing chun techniques. When a student is skilled, the dummy feels like a training partner that is happy to stand there all day as one practices on them.
