Tchoung Ta-Tchen 鍾大振 was born 1911 and passed away in Vancouver, BC Canada in 2000. He was born in Hunan Province in China. His Tai Chi practice began in 1942. Tchoung was among the earliest Tai Chi Chuan practitioners to bring the art to North America. Tchoung taught in Taiwan, South Africa, United States and Vancouver, BC Canada. In Vancouver he formed the Chinese Tai Chi Chuan Association in 1972. Shortly thereafter he was invited to become the Tai Chi master of the Seattle Tai Chi Association where he also taught many students.

Tchoung Ta-Tchen created the 6 section Dual Sided Yang Style Tai Chi Chuan Form in the late 1960's. He felt the standard Yang Tai Chi form favored the right side, which he considered unbalanced. He taught a two man partner set called "Section 7 & Section 8" and he created "section 9", a fast set combining elements of the Natural School, Tai Chi, Bagua and Hsing-I.

Tchoung Ta-Tchen began teaching in 1970 as the Tai Chi Chuan teacher for President Bongo of Gabon. He also established the South African Chinese Health and Self Defense Club in Johannesburg.

Having been one of his students in Vancouver, BC I can testify that he loved his Tai Chi Classes and his Tai Chi Students! He was like a father to us. He cried publicly when I returned to the club to visit after years away!
