I don't want to explain everything here. One simple advice though, if you believe that Shanghai
does NOT welcome you, why bother to come? Stay where you are happy... I do, I didn't pick any
other universities when I could. I stayed where I was happy. close to home. Besides, speaking
mandarin is very tiring. Don't you feel your whole mouth and teeth are tired if speaking too much
english?

Don't talk, approach or answer anyone you don't like. I don't.
