What does it mean to turn off the lights in the Gregorian calendar?

Chen Jia Yi has covered the lights.

This means that the five elements of Yin Na are covered with lights on the first day and the second day. (It's not that the lights are turned off)

When Chen eats, it is already in the corner. The sun will be at noon and the sun will shine all over the world, so it is called a cover lamp. The golden lamp shines, the jade platform shines brightly, but the sun and the moon don't shine, before dawn tomorrow.

As for the five elements, it is a matter of temperament. Not much to say here.
