What does the next renewal time in the text message refer to?

Within 7 days. Generally, the starting point is the time when the renewal operation is performed. When the next renewal time in the SMS expires, the system will remind or notify you via SMS. At this time, it will be retained for 7 days, and you can renew it in the system at any time during this period. If it exceeds 7 days and cannot be renewed, you have to go to the business hall to apply for renewal.
