Why can't I sleep outside 12 on Mid-Autumn Festival?

The fifteenth day of the seventh lunar month is the Mid-Autumn Festival. On this day, the gates of hell opened and ghosts traveled around the world. This is the heaviest moment in Yin Qi. There are many taboos on this day, and I accidentally hit a ghost. So in this lunar calendar, let's take a look at when it is forbidden to sleep on the Mid-Autumn Festival. The fifteenth day of the seventh lunar month is the Mid-Yuan Festival, and local officials forgive sins on this day. The ancients even went out at night to set off river lanterns and fire cannons for sacrifice. On the one hand, people think that the "Purdue" ceremony for these ghosts can help them get out of hell as soon as possible, on the other hand, they also hope that they will stop harassing the creatures in the world. Therefore, every July, in addition to the "Purdue" ceremony, more ghost papers are burned on the roadside in order to make a fortune. Later, it evolved into the custom of "lighting lamps" and "respecting brothers".
