>>754123The circle walking did come from taoism, it's a meditation tradition. The difference is that Dong Hai Chuan's students had different pre-existing training, and thus interpreted Bagua different ways. Yin Fu was a shaolin lohan guy, so Yin bagua has a bit more striking, makes heavy use of the 'ox tongue palm' and has animal forms. Cheng Ting Hua was a wrestler, and so his style of bagua is a lot more 'grappley'.
I don't really buy into the whole hard/soft thing. Good movement is good movement ya know, and that kind of philosophy has been used to justify a whole boatload of sub-standard training.
