I did some search on the web and found out there are many clubs out there in
big cities like Beijing. They play regularly(many times a week) and organize
events on the internet. It cost 20-80Y/hour, which isn't a big deal if they
share the cost. Really wish I was in China now. Don't know how good they are
though. I will find out in my next vacation. Check them out:
