How to handle when the system prompts' Operator expired '?

Due to the default one-year work period for operators in the system, if the system administrator does not modify the expiration date when registering the operator, the system will prompt "Operator Expired" when the operator enters the system after one year.

Solving this problem is very simple. Just use system management (default login name is gold, password is also gold) to enter the system. When the operator is "queried", use the "modify" operation to expand the "expiration date" of their operation.
