 He is most known as the teacher of the great taijiquan master Yang Luchan, but there is much disagreement over which style of martial art Chen Changxing actually taught to the family outsider.Some schools of thought suggest that Chen Changxing was a maverick who practiced and taught a style of martial art that was not part of the Chen Family martial arts tradition, and that was passed to him either directly or indirectly from a taijiquan master known as Jiang Fa.Some other schools of thought suggest that Chen Changxing re-worked two or more of the traditional Chen Family routines into his own style and then taught it to Yang Luchan and others.
