What is the holiday of Halloween?

October 31st of each year is the traditional Western holiday of Halloween, the night when children dress up in costumes and masks and go door-to-door collecting trick-or-treating. The holiday is mainly popular in English-speaking communities such as the British Isles and North America, followed by Australia and New Zealand. There are many versions of the legend of the origin of Halloween, the most common belief is that it originated in the countries of ancient Western Europe before the birth of Christ, Halloween Spooky Dogs [1] including mainly Ireland, Scotland and Wales, which were called Celtic by the ancient Western Europeans. The Celtic New Year was on November 1, and on New Year's Eve, the Celts had young men gather in processions, wearing all sorts of grotesque masks and carrying carved turnip lamps (pumpkin lamps were a later custom, and there were no pumpkins in ancient Western Europe in the earliest days) as they wandered through the villages. This was actually a celebration of the fall harvest at that time; it was also said to be a "ghost festival", and legend has it that the souls of those who died that year would visit the world on the eve of Halloween, and it was said that people should let the ghosts of those who visited them see a successful harvest and present them with sumptuous hospitality. All bonfires and lamps were built to scare the ghosts away, but also to light their way and guide them back. In medieval Central Europe, there was a history of Christianity destroying the pagans. But the ritual celebrations before New Year's Eve were never really eliminated, though in the form of witchcraft. That's why we still have traces of witches' brooms, black cats, and spells in our current Halloween. It is said that meeting a black cat on that day is the same as meeting a witch, and you will have bad luck for a year, so on that day, everyone dresses up in disguise to drive away those unlucky symbols.
