Completely unrelated to China, but one of my Korean cclassmates was explaining to me what Koreans call each finger. Basically each finger is named after a family member. It's a pretty awesome system!
Middle Finger=Older Brother
Ring Finger=Little Brother. (This one I'm not completely positive is correct. It could have been older sister but I can't remember for sure. )
I just tight this was pretty cool and would be fun too share
