Upon reading a bit more about Bak Mei Gong Fu, I came across something relating to use of Chi in the art. Chi is used as a weapon, rather than for other purposes e.g. healing...

I am slightly curious as to it's use in Xing Yi Quan/Hsing. Is Chi used as a weapon, or does it have other uses in the system? I know there are various styles of Xing Yi, and that variations may apply within indivdual styles/schools, but what is the general use?

Many thanks for any help! I am a serious noob re CMA, so apologies if my ignorance shows!
