It is well known for its smooth, flowing movements which omit the more physically vigorous crouching, leaping and fa jin of some other styles.
Today, Sun-style ranks fourth in popularity and fifth in terms of seniority among the five family styles of tai chi.
Besides his earlier xingyiquan and baguazhang training, Sun's experiences with Hao Weizhen, Yang Shaohou, Yang Chengfu and Wu Jianquan influenced the development of what is today recognized as the Sun style of tai chi.
[2] The Sun style is a syncretic martial art, influenced by tai chi, xingyiquan and baguazhang.
Sun-style tai chi teachers in the USA include Tim Cartmell in Huntington Beach, CA, Way Sun in Chicago, Michael Garofalo in Red Bluff, CA, Aiping Cheng in Austin, TX, and Justin Harris in Fort Worth, TX.
