If it is in a different place in China, you can go to ICBC for domestic transfer (remember to provide complete remittance information, such as payee name, payee account number, payee bank name and address, etc.). ) or if it is your personal HSBC account, you can withdraw money directly from ICBC to the local HSBC for remittance (if it is foreign currency, the deposit will be limited. If there is no local account, you should open a new one, so it is actually the most convenient for ICBC to remit money directly.
If you transfer to an overseas HSBC account, and it is not your account with the same name, the RMB should not be allowed to drop, but it involves foreign currency. If there are restrictions, it will be too vague to analyze your problem in detail.
