1. Check. He mailed the check and I took it to China Bank for clean collection. If China Bank charges a handling fee, the other bank will sometimes charge it. Generally, banks in China charge RMB 20 to 30 yuan, while banks in the euro zone charge 2.5 euros (except German). Generally, you can receive the money about one month after receiving the money. If you don't want to change it into RMB, you can bring foreign paper money or deposit foreign exchange.

2. Bank wire transfer. I have a multi-currency passbook in ICBC. I once remitted a sum of money from Germany to this passbook. The operation is as follows: tell the other party your account name and account number and the SWIFT code of the bank where the account is opened, and the money will arrive within one week after the transfer. It's foreign exchange (you can receive as much as he transfers).
