actually, I am Chinese and I found it is hard to use CNY to deposit to buy
BTC
maybe you will ask why don't use Chinese exchangers or why not ask in a China forum. cause I suppose the foreign one is more reliable.
AFAIK, there is a Bitcoin ATM which you can use to purchase Bitcoins. If there isn't, localbitcoins.com would be the best choice.
fine, thank you so much

According to
http://www.coindesk.com/bitcoin-atm-map/, there are only 4 places you can find a bitcoin ATM in China, which is Beijing, Shanghai, Macau and Hong Kong.
If you don't live near those 4 cities, the best option IMO is to use localbitcoins.
