Legal basis: Measures for the Administration of Bank Accounts Bank account management follows the following basic principles: (1) One basic account principle. That is, depositors can only open a basic deposit account in one bank, and cannot open a basic deposit account in multiple locations. When a depositor opens a basic deposit account in a bank, the local branch of the People's Bank of China will issue an account opening permit system. (2) The principle of voluntary choice. That is, depositors can choose their own bank accounts, and banks can also choose depositors to open accounts voluntarily. No unit or individual may forcibly interfere with depositors and banks in opening or using accounts. (3) The principle of deposit confidentiality. In other words, banks must keep depositors confidential according to law and maintain the independent control of depositors' funds. Except for matters regulated by the head office of the People's Bank of China authorized by national laws and the State Council, banks shall not inquire, freeze or deduct deposits in depositors' accounts in the name of any unit or individual.
