Just the only way to buy bitcoin is to locate people from your country here in the forum, send them your address to send you bitcoin while you send CHY to them, with this while making transactions you wouldn't include any cryptocurrency related words therefore, they wouldn't question you for having transfer of money to other account. This is similar to our country as well, when you make transaction and include cryptocurrency related words automatically your account is blocked. you can transfer on P2P (person 2 person) without any restrictions, and of which you wouldn't dare using any crypto word while sending out payment to him.
Can you trust having a transaction with someone who is not ready to buy Bitcoin but prefers begging one way or another? I believe OP is familiar with Bitcoin this means he is somewhat familiar with how to buy Bitcoin if he wants to but he chose to ask for help here. However, your suggestions are good he should identify his local board there are persons who will be willing to have a fair trade with him.
The second one is fly to Macau or Hongkong, Bitcoin is legal there.
Well said.
He can also visit Shenzhen and cross the border to Hong Kong. There are Bitcoin ATMs and brick-and-mortar crypto exchanges in Hong Kong where he can buy Bitcoin with ease.
