Master Wei Shu Ren coaching Dr. John Fung at Temple of Heaven Beijing 1998.

There are many versions as to how Tai Chi was developed. Most people today believe it was first developed by a Taoist priest named Chang San-Feng who lived in China during the late Sung Dynasty. Some historians calculated that Chang would have lived to about 250 years old. The art was passed on to the Chen family a few generations later, and the founder of Yang Style Tai Chi, the legendary master Yang Lu Chan (1780-1873) learnt the art from the Chen family.

Yang Lu Chan was such a great fighter he was nicknamed "Yang the Invincible" during his time in Beijing. His son Yang Jian Hou served in the Manchurian court as Prince Bolin's personal bodyguard, and taught the art to the royals during the late Ching Dynasty. Yang Jian Hou's youngest son Yang Chen Fu left Beijing and went to Shanghai where he modified the system and taught the art to the public. He taught many very accomplished martial artists.

The Imperial Yang Family Tai Chi descended directly from the Beijing imperial branch, where Yang Jian Hou taught Wang Yong Chuen, Wang taught Master Wei Shu Ren, and Master Wei taught a handful of disciples including Dr. John Fung who resides in Sydney, Australia.

Dr. Fung is a dental surgeon practising in the eastern suburbs of Sydney Australia. Dr. Fung is also a former Clinical Associate at the University of Sydney, teaching final year students in the Dentistry Faculty. Recently, Dr. Fung had completed his medical acupuncture certificate and is successfully applying his acupuncture knowledge into his dentistry and martial arts. With his background in science and teaching, Dr. Fung has organised Martial Arts, Acupuncture, Qigong and Master Wei's teachings into an easy to understand, step by step format. The REV (Reverse Energy Vectors) system developed by Dr. Fung combines traditional Chinese teachings and Western science and summarises the essence of Tai Chi power generation and combat techniques into a nut shell; forming the basis for anyone to learn and build on and expand, and may be one day to elevate the practitioner to new heights of excellence. Dr. Fung teaches the art openly in Sydney. He is one of the very few certified by Master Wei to teach the art and continue the line. Dr. Fung is a 6th generation disciple of the Imperial Yang Tai Chi system.
