Just send it to his/her bitcoin address like normal. Chinese users can use blockchain.info chan't they?
Well, the OP stated that that wasn't his real problem further down in the thread. Here's the quote.

actually i need to know how easy is for the person in china to convert/exchange bitcoin for the local currency,
not in the china banks i suspect, but working with some bank account who can receive the already converted bitcoins/yuens... is there any way to do that in a more automatically way??:
