How to set Redmi Watch 4 standing reminder?

Enable [Standing Reminder] in the Mi Fitness App, and the standing reminder will be sent if there is no walking or strenuous hand activity within one hour, but the following conditions need to be considered:
(1). If there is ever walking or wearing the watch sports behavior in one hour, the reminder will be extended for half an hour, and the delay time will not exceed one hour;
(2). The reminder will be delayed for half an hour if the hand strenuous activity reaches 10 seconds, and for one hour if it reaches 20 seconds; 
(3). The current time point is within the reminder time range set by yourself (pay attention to the open lunch break time disturbance-free function, the default is 12:00 ~ 14:00);
(4). No standing reminder during exercise.
