If one day the bank suddenly receives a sum of money, the payee is this sleeping account, or the owner of the account finds the bank and asks to activate the account, then the bank will manually activate the account, and internally execute a program to change the status of the account back to the normal available state, and the account can be used.
Sleeping account, also known as long-term fixed account, refers to an account that has been sleeping for a long time and has no business. This kind of account generates neither deposit interest nor any fees.
