First, does SS Shaolin teach to strike with the bottom three knuckles for punching?
Second question is a bit more involved. I'm curious about the parallels between two similar movements. One in SS and one in BSL.
I was watching a clip of Xiaohongquan today and there's a move that involves the practitioner bringing the arms to the chest, then rotating while throwing the arms out, one to punch and the other to(presumably) add more force to the strike. http://www.youtube.com/watch?v=8E2JeUXQRa8 at 0:23 in that clip.
To me, it looks like this could have been the same movement you see in BSL Tan Tui at one time in the past. Perhaps an evolution over time?http://www.youtube.com/watch?v=JI9dH62UpYs One of the opening moves at 0:05
If not, what is the purpose of this movement for each style? I understand there's a huge article on the comparisons of SS and BSL. Just curious about this movement in particularly, though.
