Yang Chengfu
Yang Zhensheng (楊振聲, Pinyin: Yáng Zhènshēng; 1878-1939) trained to a high level of skill under his father Yang Shaohou and his uncle Yang Chengfu, and went on to teach t'ai chi ch'uan in Shanghai and Kunming in the 1930s. During the Japanese occupation he went missing in Hebei and was never found, but three of his sons and their many descendants have continued the Yang family t'ai chi lineage.
