Yangjia Michuan Taiji Quan , the Yang Family Secret Tradition is a t'ai chi ch'uan style created by Yang Lu-ch'an, founder of the Yang style. He passed this special style to his son Yang Chien-hou who transmitted it to his student Zhang Qinlin. Master Wang Yen-nien was taught the Yangjia Michuan by Zhang Qinlin and chose, in order to avoid the disappearing of this style, to teach it to a great number of students all over the world.
