His direct descendants, the many students he taught, and their students, have spread the art around the world. Among Yang Chengfu's students were famous masters such as Zhao Bin (his older brothers grandson 1906-1906)
Dong Yingjie,
Chen Weiming,
Fu Zhongwen, Li Yaxuan (李雅轩; 1894–1976) and
Cheng Man-chʻing. Each of them taught extensively, founding groups that still teach tai chi to this day. Cheng Man-chʻing, perhaps the most famous outside of China, significantly shortened and simplified the
traditional forms Yang taught him after his teacher's passing, reportedly to make them more accessible to larger numbers of students. Although Cheng's modifications are considered controversial by most other schools and are not recognized by the Yang family, Cheng Man-chʻing is known as one of the first to teach tai chi in the West. His sons have continued to teach their
father's tai chi, including his first son, the late
Yang Shouzhong (1910-1985), who brought Yang-style tai chi to
Hong Kong, his second son Yang Zhenji (1921-2007), his third son,
Yang Zhenduo (1926-2020), who lived in
Shanxi Province, who was widely considered the most prominent of the Yang family tai chi instructors, and his fourth son, Yang Zhenguo, born in 1928, and living in
Handan,
Hebei. ==Bibliography==
