Halloween, also known as all saints' day, is a traditional festival in the West on November 1 every year, while October 31, the eve of Halloween, is a lively time of the festival. In Chinese, Halloween is often wrongly translated as all saints' day.

Children will dress up as all kinds of cute knock on the door, asking for candy, or they will make trouble. At the same time, it is said that on this night, all kinds of people will dress up as children and join the masses to celebrate the coming of Halloween, while human beings dress up as various kinds in order to make them more harmonious.

More than 2000 years ago, the Christian Church in Europe designated November 1 as "All Hallows' day.". "Hallow" means saint. It is said that Celts living in Ireland, Scotland and other places moved the festival forward one day since 500 BC, that is, October 31. They think it's the official end of summer, the beginning of the new year and the beginning of a harsh winter.

At that time, it was believed that the souls of the dead would return to their former residence on this day, looking for life on the living people, so as to regenerate. Moreover, this is the hope that people can obtain regeneration after death. On the other hand, the living people are afraid that the souls of the dead will seize life. Therefore, people put out the fire and candle light on this day, so that the souls of the dead can not find the living people, and they dress up as monsters to scare away the souls of the dead. After that, they will light the fire and candle light again and start a new year's life.

In fact, Halloween is a celebration of autumn, just as may day is a celebration of spring. Druid, the ancient priest of Gaul, Britain and Ireland, had a grand festival to celebrate autumn, which lasted from midnight on October 31 to November 1 the next day. They believe that on that night, their great God of death, Saman, called all the ghosts of those who died that year, and that these evil spirits would be punished by raising themselves to animals. Of course, as long as you think of this kind of ghost gathering, it is enough to make those simple minded fools at that time scared. So they set up a bonfire and kept a close watch on the evil spirits. That's how the idea of witches and ghosts everywhere on Halloween begins. Up to now, in some isolated parts of Europe, some people still believe that this is true.

The ancient Romans also had a festival on November 1st to pay homage to their goddess Pomona. They bake nuts and apples in front of a raging bonfire. Our Halloween seems to be a combination of Roman festivals and Druid festivals.

It turns out that the activities of Halloween are very simple, and most of them are held in the church. But throughout Europe, people see Halloween as an opportunity to have fun, tell ghost stories and scare each other. So people no longer use this festival to praise autumn, but let it become a festival of gods, witches and ghosts.
