Origin of the name Halloween

Halloween English is All Saints Day, one of the Catholic and Orthodox holidays, a traditional holiday in Western countries. Halloween is often mistaken for Halloween in Chinese-speaking areas. "Hallow" is derived from Middle English halwen, close to the holy etymology, and in some areas of Scotland and Canada, Halloween is still called "All Hallow Mas". On that day, the Mass is celebrated in celebration of all the saints in heaven (Hallow). Nowadays, the society organizes various activities full of demons and monsters on the night of October 31 for commercial interests or other purposes, which is completely contrary to the sacred meaning of Halloween.
Regarding the origin of Halloween, there are many versions, and the more widely circulated are:
More than 2,000 years ago, the Catholic Church in Europe designated November 1 as "All Hallows' Day." [9] "Hallow" means saint. Legend has it that the Celts, who lived in Ireland, Scotland, and other places, believed that October 31 was the day when summer officially ended, that is, the beginning of the new year, the day when harsh winter began. At that time, it was believed that the souls of the deceased would return to their former homes on this day to find the living in the living and regenerate, and this was the only hope that people could be reborn after death. The living are afraid of the souls of the dead coming to take their lives, so people put out the fires and candles on this day, so that the souls of the dead cannot find the living, and they dress themselves up as demons and monsters to scare away the souls of the dead. After that, they will rekindle the fire and candlelight to start the new year.
Halloween was originally a celebration of autumn, just as May was a celebration of spring. The ancient priests of Gaul, Britain and Ireland, the Druids, had a grand festival in praise of autumn, which lasted for an entire day from midnight on October 31 to November 1, the next day. They believed that on that night their great god of death, Saman summoned all the ghosts of the dead that year, and these evil spirits were to be punished by being born as animals. Of course, the mere thought of such a ghostly gathering was enough to terrify the simple-minded fools of the time. So they lit bonfires and closely monitored these evil spirits. This is how the story of witches and ghosts everywhere on Halloween Eve began. To this day, in some isolated parts of Europe, some people still believe this is true.
The ancient Romans also had a festival on November 1, which was used to pay homage to their goddess Pomona. They roast nuts and apples in front of a roaring campfire. Our Halloween seems to have been a mix of ancient Roman holidays and Druid's festivals.
Halloween activities turned out to be very simple, and most of them were held in churches. But across Europe, Halloween is seen as an opportunity to have fun, tell ghost stories and scare each other. So people no longer use the festival to celebrate autumn, but to turn it into a festival of gods, witches and ghosts.
