I'm sure many practitioners of Chen knows who Grandmaster Feng Zhiqiang and Master Yang Yang are. If not, go to http://www.chentaiji.com
Because of the Xing Yi influence of what they do, they call their art:
Chen Shi Xin Yi Hun Yuan Taijiquan
But what is the difference? Is it "more internal" than the traditional Chen because of Xing Yi? Sounds strange.
I'd appreciate any help with this.
