How to display the lunar calendar by locking the screen of vivo mobile phone

Vivo mobile phone lock screen shows lunar calendar:

Origin OS system: Enter Settings-Desktop, Lock Screen and Wallpaper-Lock Screen Settings, set the lock screen style to the built-in style, and turn on "Lock Screen Display Lunar New Year"; If the day is a holiday, the name of the holiday will be displayed first, and the lunar calendar will not be displayed;

Funtouch OS/iQOO UI system: Some models (such as S6) support the lunar calendar display with default screen locking style, and the unsupported models can choose the I theme with lunar calendar display.
