Looks like it's not gonna work. You should be legal China citizen with a ID which used for authentication of exchanges(1), you also need
that ID for getting a bank card(2), the name you registered in exchange should be the same with name you used to get that card. And looks like CNY is the only one withdrawal option left to us.
you want to sell Bitcoin in Chinese exchanges?
Yeah. I don't think you can do that. But I don't really know much about Chinese exchanges.
