Someone mentioned taking a protein shake with. I think if you going to train anywhere in china, this is probably the best advice to take. Last year April I was with a group of Foreigners from all over the world doing an international san shou instructors course in wuhan, and nearly everyone eventually went out to buy some protein shakes. Chinese food usually consist of loads of carbohydrates and very little protein. Probably ok for smaller Chinese body types, but for the bigger westerners I suppose a supplement could be welcome.
