The Wu family style (Chinese: 吳家
or 吳氏) t'ai chi ch'uan (Taijiquan) of Wu Quanyou and Wu
Chien-ch'uan (Wu Jianquan) is the second most popular form of t'ai chi
ch'uan in the world today, after the Yang style, and fourth in terms
of family seniority. This style is different from the Wu style of t'ai chi
ch'uan (武氏) founded by Wu Yu-hsiang.
