I am located in China, bitcoin is not allowed to use. Anyone can help?
I'm not completely sure what kind of help you're looking for.
But nobody can stop you from creating a seedphrase or a private key, derive the address and have somebody fund said address. However, finding someone to fund your address might be a hassle if it's illegal to have bitcoin. Maybe you can arrange something P2P, or find an exchange that's willing to trade a legal form of payment for bitcoin without requesting KYC?
But whatever you do, or whoever you find, you must realise that nothing we do will make something that's illegal in your country legal...
