If you are in a new county (Guo Hong), there are many supermarkets and Red Crescent supermarkets everywhere. This is a local supermarket chain in Panxian county, which is large and small and very convenient. Panxian county is small and there is no Wal-Mart.
If you are in town or something, go and see what supermarkets there are on the street. There are usually Red Crescent supermarkets, but now they all seem to be called convenience stores. That's all I know. I haven't been to Panxian for several years, but I only know Red Crescent ~ ~
