When I meet with Yan Zhuang shifu again I'll find out as much as I can about it.

THis luohan quan is definately not from Degen da shi. Its not the 18 luohan, it uses different basics. But it is an awesome form.

He said er lo has 108 movements and yi lu is short. I'll find out more and see if I cant study all 3. I have a suspicion that his er lo may be the long set in the encyclopedia (deqian).
