I has read through this articles - http://www.ymaa.com/articles/martial-ar ... ing-qin-na. There are Fen Jin Chin Na and Cuo Gu Chin Na. What are they? I have Analysis of Shaolin Chin Na by dr. Yang, but there aren't technics with these names.

Fen Jin I believe is "splitting tendons." So something like finger dividing. In the context of the article, it says if you do not use Jin to apply the technique, your opponent will counter your Qin-Na (and thus, protect his/her tendons) simply by using their muscular force.

Cuo Gu means something like "displacing bones." In the context of the article, it also mentions breaking bones.
