After opening an account, the bank will give you an information form. It has your administrator account and password on it. Then you can find a computer with Internet access and log on to the application service platform of the State Administration of Foreign Exchange. Create an operator after logging in. Remember to give all permissions. Then all your foreign exchange income will be declared from this system in the future. Log in as an operator and follow the instructions. It must be noted that this is a matter of time. Don't be overdue, or SAFE will find trouble again.
