What does the reminder mean?

There is only one difference between reminders and reminders, that is, the difference between paying and paying.

Hand in is hand in, hand in, hand in, hand in papers, and hand in is hand in, such as paying fees and handing in.

Whether it is a reminder or a reminder, it will be distributed to individuals in the form of a reminder letter. This is the reminder and notice used by the payer or individual when the payment is overdue.
