You can fill in the SWIFT code of CCB head office, that is, PCBCNBJ, and then the payee's branch name, account number and account name must be correct, so that you can receive the payment, but it may be slower. If you want to be direct, you should fill in the SWIFT code of the provincial branch, that is, there must be three letters or numbers after PCBCNBJ. Details can be found in SWIFT official website.
