Do you have any other accounts in online banking? Use your online banking key to transfer money directly from a rich account to an account that you have no money. If you earn won in South Korea and remit it directly to your account in China, banks in China cannot operate, because first, even if they can accept won, you have to open a won account for you, otherwise you can only exchange won for RMB and then enter it in the account; Second, if they can't accept won, your money will be returned. See if Korean banks can remit RMB. It will be much more convenient for you to remit RMB. Trouble is useless. Who calls this foreign exchange? China has foreign exchange control.
