Mid-Autumn Festival is a ghost festival. On the night of July 14, at midnight, Yin Qi is the biggest one in a year. At this time when there are the most ghosts, there will be thousands of ghosts coming up from the underworld. In fact, these are all folk rumors, which people gradually believe, that is, superstition. If you believe in superstition, you don't believe it, mainly to let future generations pay homage to the dead.
