Zhang Sanfeng
Zhang Sanfeng, a highly mythologised figure said to be the founder of t'ai chi ch'uan, lived in the Wudang Mountains and the name "Wudang" used for this T'ai chi ch'uan system was used in order to acknowledge Zhang Sanfeng's status as the founder of t'ai chi ch'uan. There are other schools of T'ai chi ch'uan that also use this name.
