The latest issue of KF Taichi has an nicely done article by Mr. JOhn Page in it on "Xing Yi Taichi." OVerall the article was well put together, but I have one question regarding a comment made within the pages....
The author states that Guo Yunsheng mixed Taiji with their Che Style Xin Yi creating a hybrid system of internal martial art. Subsequently Guo passed on his teachings to Bu Xuekuan, and Sun Lu Tang. The author then goes on to say that Sun's Taiji system was in fact NOT created by Sun, but rather it is the hybrid Xing Yi-Taiji system as passed on by Guo.
I find this quite interesting, but the rest of the article mentions nothing else in regards to this claim. So I was wondering two things:
1) What proof does the author have in making such a claim?
2) Has anyone else heard of this before? This is a new one to me, but alas I am still quite young in the martial arts so perhaps something has alluded my understanding.

Cheers
