What's the procedure for transferring money from Viet Nam to China Agricultural Bank?

The licensed branch of the Agricultural Bank of China remits foreign exchange or takes the remittance slip from the computer online banking operation counter, and fills in the account name and address with the bank card ID card. Ask the bank code of China Agricultural Bank and China Agricultural Bank, or fill in the form directly and sign it for the remittance staff to collect money. The work account fee seems to be 1-3. The remittance amount seems to be 100-200 yuan. Choose your own expenses and choose all remittances. It is still cost-effective to charge 25 yuan directly. I know that the Agricultural Bank of China has to pay a handling fee for inter-bank.
