In thirteen years of study (1961-1974) under Master Cheng, Dr. Yang became an expert in the White Crane style of Chinese martial arts, Qin Na, Tui Na and Dian Xue massages, and herbal treatment. At the age of sixteen, Dr. Yang began the study of Taijiquan (Yang Style) under Master Kao, Tao (高濤). Dr. Yang's tai chi can be traced back to the Yang family through Master Kao's teacher Yue, Huanzhi (樂奐之), an indoor disciple of Yang, Chengfu (楊澄甫). less
