WUDANG (武當) STYLE
Tai Chi of Cheng Tinhung
(Cheng Tin Hung / 鄭天熊 / Zheng Tianxiong)
Cheng Tin-hung was a Hong Kong based martial artist from San Xiang in Guangdong Province. His teachers included Qi Minxuan 齊敏軒 and Cheng Wingkwong (1903-1967).
This style is very similar to Wu style.
Cheng Ting Hung was a strong and public proponent of the martial effectiveness of tai chi, training competitive full-contact fighters and taking several high profile challenges himself. One of the competitive fighters he trained was Dan Docherty, who won the 1980 South East Asian Chinese Pugilistic Championship in Malaysia (competeing in the open weight class).
The main centres for this school are the Hong Kong Tai Chi Association run by Cheng Kam-Yan (鄭鑑恩), and Practical Tai Chi Chuan in England, run by Dan Docherty.
