Yang-style t'ai chi ch'uan
Chengfu is known for having "smoothed" out the somewhat more vigorous training routine he learned from his family as well as emphasising a "large frame" or "Da Jia (大架)" with expansive movements in stepping and using large circular motions with the arms. His smooth, evenly paced large frame form and its hundreds of offshoots has been the standard for Yang-style t'ai chi ch'uan (and overwhelmingly in the public imagination for T'ai chi ch'uan in general) ever since.
