How does Meizu 4pro set the morning alarm clock to display the weather?

Weather conditions: press your finger on the blank space of the screen, add the plug-in and release it. Click Add Plug-in and put the weather item in the area you want.

Alarm clock: Click the alarm clock, then click Add Alarm Clock to set the time, date, volume, etc.

The latest version of Meizu mx4 pro has this effect. When the screen is locked, the alarm clock rings. The background is the current weather effect.

In other words, as long as the alarm is set, it will have this effect. But the system must be the latest version.
