Where to train in China ?

Here is a short list of places where you can train in China (still a work in progress):

Beijing
Beijing Jiu-Jitsu Academy
Beijing Black Tiger Academy
MMA Beijing

Guangzhou
Yong Guang Judo Training Center (in chinese)

Shanghai and Hong Kong are coming soon (once I've done some more research). Meanwhile, let me know if you know of good places to train (Sanda, Muay Thai, or Chinese martial arts suggestions are welcome too).

As a general tip, whenever you're in a big enough city, you can go check out the training facilities for the members of the city or region teams in various sports (wrestling, judo, boxing...). They might be nice enough to let you train with them.
