When my friend's daughter (senior HS) went to China with her volleyball team, they were told to drink only beer. You could maybe drink bottled water IF it comes to your table sealed.

China uses "night soil" (human manure) to fertilize their food fields, and this stuff is NOT composted to remove pathogens. All the raw food rules apply here.

I would take a supply of the best water sterilization product I could find, and a good supply of Immodium, also.

I don't know if it is true, but I have heard that in Third World countries Giardia & Cryptosporum are NOT nearly as common as here.
