I was tied up on Halloween.

Regarding the origin of Halloween, the most legendary version holds that it originated in ancient western European countries before the birth of Christ, mainly including Ireland, Scotland and Wales. The ancient Western Europeans in these places were called Drouth people. The New Year in Drouth is 1 1 month 1 day, New Year's Eve. People in Drouth let young people wander among villages in groups, wearing all kinds of weird masks and carrying carved radish lanterns (pumpkin lanterns are a late custom, and there were no pumpkins in ancient Western Europe). It was actually celebrating the autumn harvest; Some people say it is "Ghost Festival". It is said that the souls of those who died that year will visit the world on Halloween. It is said that people should let visiting ghosts see the harvest and show rich enthusiasm to them. All the bonfires and lights, in order to scare away ghosts, also illuminate the route for ghosts and guide them back.

In medieval Central Europe, there was a history of Christianity destroying pagans. However, the sacrificial ceremony before New Year's Eve never really disappeared, but appeared in the form of witchcraft. That's why we have traces of witches' brooms, black cats, spells and so on on Halloween.
