Dr. Yang, Jwing-Ming started his Gongfu training at the age of 15 under the Shaolin White Crane Master Cheng, Gin Gsao. Dr. Yang became an expert in the White Crane style of Chinese martial arts. With the same master he also studied Qin Na, Tui Na and Dian Xue massages, and herbal treatment.

At the age of 16, Dr. Yang began the study of Taijiquan under Master Kao, Tao. Dr. Yang's tai chi can be traced back to the Yang family through Master Kao's teacher Yue, Huanzhi, an indoor disciple of Yang, Chengfu.

After learning from Master Kao, Dr. Yang continued his study and research of Taijiquan. Dr. Yang has mastered the Taiji barehand sequence, pushing hands, the two-man fighting sequence, Taiji sword, Taiji saber, and Taiji Qigong.

Dr. Yang has been involved in Chinese Gongfu since 1961. During this time, he has spent 13 years learning Shaolin White Crane, Shaolin Long Fist, and Taijiquan. Dr. Yang has more than thirty years of instructional experience.
