How to set the standing reminder on the Xiaomi Watch S3?

Turn on the [Stand Reminder] switch in the [Mi Fitness] APP. If there is no walking or strenuous hand activity within an hour, a stand reminder will be sent.
To receive the reminder normally, however, the following conditions need to be considered:
1. If there is any behavior of walking around or wearing the watch for exercise within one hour, the reminder time will be extended for half an hour, and the delay time shall not exceed one hour;
2. If the violent hand activity reaches 10 seconds, the reminder time will be delayed for half an hour. If it reaches 20 seconds, the reminder time will be delayed for one hour;
3. The current time point is within the reminder time range set by you (note that the [DND] function is enabled during lunch break, the default time is 12:00~14:00).
