Wudang t'ai chi ch'uan (武當太極拳) is the name of a system of t'ai chi ch'uan (taijiquan) that was developed by a Hong Kong based t'ai chi ch'uan master known as Cheng Tin hung. While Cheng Tinhung never claimed to be teaching any particular school of t'ai chi ch'uan, his uncle was a disciple of the Wu school of t'ai chi ch'uan, which may or may not have had some influence on his own approach to the art.
