How to turn off Huawei watches?

Huawei watches have three shutdown modes, namely: 1. Press the button to shut down: press and hold the "up" button of the watch, and then choose to shut down after the "restart/shutdown" screen appears; 2. System shutdown: Click the watch "Up" button to enter "System Settings", click "System Menu" and select shutdown; 3. Automatic shutdown: the watch will automatically shut down after the vibration prompts the ultra-low battery.
