Usually, foreign remittances are wired to your foreign currency passbook opened in the bank. When you open an account in a bank, the bank will leave your phone number. When the remittance arrives, you will be called to pick it up. Just go to the bank with your ID card. There is no money order. If you want to change RMB, you can change it directly when you handle it.
Simply put, after the bank staff calls you, you just need to take your ID card to withdraw money.
