楊氏太極拳
Chang taught at the Nanjing Central Kuoshu Institute () and was the youngest faculty member at the time. There, he exchanged knowledge with other martial arts experts. He created his own variation of t'ai chi and xingyi, Chang t'ai chi, based on Yang-style t'ai chi ch'uan, xing yi and his Shuai Jiao knowledge. Chang traveled across all China and studied under around 70 masters, always introducing himself as a simple student in order to learn everything possible.
