What does it mean that the ghost door opens on July 15?

You can't go out at night on July 14 and 15. These two days are called Ghost Festival, which is the Mid-Autumn Festival.

Mid-Autumn Festival is the most important of the three ghost festivals in China: Qingming Festival, Hanyi Festival and Mid-Autumn Festival. It is said that on this day, the doors of the underground palace are open, ghosts travel, and dead ancestors can go home for reunion. The Taoist temple will hold a grand ceremony and pray for the auspicious Dojo to cross over the soul of the deceased. People should put steamed buns at the door for ghosts to eat; In some areas in the south, it is necessary to worship ancestors, go to graves and light lanterns to light the way home for the dead.

It's a bit like Halloween. Halloween is a ghost festival in the west. As soon as it gets dark, the children dress up as ghosts and beg for candy from door to door, shouting "trick or treat" The difference is that orientals are introverted. On the night of Mid-Autumn Festival, people have to hide at home after offering sacrifices and giving alms at the door. ?

After all, it is forbidden to make mistakes accidentally on Ghost Festival. I remember when I was a child, I often saw green "ghost lights" and "ghost fires" in the countryside (in the late 1970s) and in the fields on summer nights. Adults tell children that it is a ghost on the road, and they never chase or fight out of curiosity. Especially in the seventh month of the lunar calendar, the old people set various taboos because the Ghost Festival is coming.
