You'll be in for a suprise in mainland China...martial arts are not very commercialized there. Don't forget China only started opening its markets very recently. I was there earlier this year and don't remember seeing a single school, although I met one couple whose kid was learning tkd.
Secondly, Chinese in general don't usually esteem foreign (i.e., non-Chinese) martial arts highly. Not to say that none do, simply very few. So that makes the chances even less likely.
If you are interested in finding Chinese martial arts, and you don't already know someone there who can help you look, you might try contacting a university, because often they will have teams, and have classes available for non-members. Also, search the internet. In China, the sites you can reach will differ from the ones you can reach here, I found out.
Good luck, and if worse comes to worse, Tsingdao makes some fine beers that you can't get here.
