Hey guys, I found more clips!

I just googled for xingyi out of the blue, and I found this. I've never seen it before. Needless to say, it doesn't look very good, at least the Pi Chuan I've seen so far.
**Ok, well some of the clips don't look half bad. The drilling fist is similar to how we do it, but it still looks external.
