T'ai chi ch'uan
The Wudang t'ai chi ch'uan system is also known as “Practical T'ai chi ch'uan”. This name comes from that given to Cheng Tinhung's style by various Chinese martial arts journalists in Hong Kong during Cheng Tinhung's heyday, and from the school's assertion that its t'ai chi is eminently useful as a form of self-defense.
