I would like to suggest you to completely avoid any chinese exchanger if you are not actually from China. They have implemented very strict KYC policy and you may end up losing whatever you will deposit there.
Why you like to sell your bitcoin to chinese and how you gonna get those Yuan if you are not from china.
Yes, bitcoin is very cheap in my country, and the demand is quite high in China. I have compatriots as well selling to Chinese (long time trusted partners), so I thought that could make sense. I can convert the yuan to dollar or to my country's local currency as well.
Since the exchanges require strict KYC, that is why I want to avoid them completely and rather trade with individual merchants.
