Shanghai is not a very expensive city; at least if you have toured several western cities, you will find that a trip to Shanghai is much too economical. Of course, there are various five star hotels and such here too, so you can decide your own upper limit of spending. But, the bottom line is, if you want to have a budget trip to Shanghai , you can do so quite easily.

The locals in Shanghai are quite friendly, and they are conscious of the appeal their city has with foreign tourists. They will make you feel at home. Language could be a problem, though. But in most places that matter, you will find that a healthy amount of English is spoken. You need not be worried about your dress as such, being a tourist, but very overt physical expressions are not accepted in some sections of Shanghai .
