When to turn on the light and when to turn off the light.

According to the old traditional custom, during the Lantern Festival, lanterns are tied and hung on the thirteenth day of the first month, that is, lanterns are put on the eighteenth day of the first month, that is, lanterns are put on. There is a folk proverb: "On the thirteenth day of the first month, you will eat jiaozi; On the eighteenth day of the first month, turn off the lights and eat noodles. "And turning off the lights means that the Lantern Festival is over and people have to go to work and go to school formally.

In addition, the fourteenth day of the first month is a "light test", the Lantern Festival on the fifteenth day of the first month is a "positive light", and the seventeenth day of the first month is a "stop light".

The day when all families try to make a good lamp is called "lamp holder". In the old society, the lights were turned on on the thirteenth day of the first month and turned off on the eighteenth. There is a saying that "thirteen or four gods look at the lights, fifteen or six people look at the lights, and seventeen or eight ghosts look at the lights", and there is a move of "turning on the lights and turning off the lights".
