Yang Luchan went to Chenjiagou to steal boxing, which was widely circulated. However, it is worth mentioning that Yang Luchan stole boxing first, and then learned it from the master. After he came back, he studied Tai Ji Chuan with Wu Yuxiang, the founder of Wu Tai Chi, in a cigarette shop for a month. This is recorded in writing. Later, after theoretical practice, Yang obviously changed many boxing formulas and moves. So not like Chen, but like wu-tang clan. The reason is that Wu Yuxiang was lucky enough to get Tai Ji Chuan's theory from Wang Zongyue, and Wang Zongyue should be an extension of wu-tang clan.
