The Muk Yan Jong (木人樁; pinyin: mùrénzhuāng; Yale Cantonese: muk6 yan4 jong1; literally “wooden man post”) is a wooden dummy used in Chinese martial arts training. It is associated with the martial art of Wing Chun and other Kung Fu styles of Southern China.
The muk yan jong has three arms and one leg, which represents an opponent’s body in various positions. The wooden slats on which the muk yan jong is traditionally mounted have a springiness that is similar to a human opponent’s involuntary reaction and allows the user to practice absorbing energy into his stance.
