Yin shou gun

[LFJ]

We also have Tang Lang Yim Yuen Gun = Yin-Yang Stick which I haven't learned yet...

there is a shaolin yinyanggun as well. this is the only video i've been able to find of it: http://www.56.com/u73/v_MTU1MjM4Nzg.html

BTW, I'm currently learning a variation of yinshougun from Shi Yanfei. The latter half of his form is completely different than what most everyone is practicing nowadays. It's very interesting.

i've seen these types of forms, but they looked just like an extended version of yinshougun. but the extra movements also seemed modernly created. it didnt have the same feel as regular old yinshougun when it changed. but it was still very cool.
