In western countries, every year on1October 3 1 day, there is a "Halloween", which is interpreted as "The eve of All Saints'Day" in the dictionary and translated as "Halloween night" in Chinese. Halloween is a traditional festival in western countries. This night is the most "haunted" night of the year, so it is also called "Ghost Festival".

More than two thousand years ago, the Catholic Church in Europe designated 1 1 month 1 day as "ALL HALLOWS DAY". "HALLOW" means saint. Legend has it that since 500 BC, CELTS living in Ireland, Scotland and other places moved this festival forward by one day, that is,1October 3 1 day. They think that this day is the day when summer officially ends, that is, the beginning of the new year and the beginning of the harsh winter. At that time, people believed that on this day, the dead soul of the deceased would return to the former residence to look for living beings, so as to be reborn, and this was the only hope for people to be reborn after death. The living are afraid of the dead soul to seize life, so people put out the fire and candlelight on this day, so that the dead soul can't find the living, and dress up as monsters to scare away the souls of the dead. After that, they will rekindle the candlelight and start a new year's life. Legend has it that the Celtic tribes still had the custom of killing the living on1October 3 1 day to pay homage to the dead.

By the 1 century, the Romans who occupied the territory of Celtic tribes gradually accepted the custom of Halloween, but since then the barbaric practice of burning the living to sacrifice the dead has been abolished. Roman festivals celebrating harvest were combined with Celtic rituals, wearing terrible masks and dressing up as animals or ghosts in order to drive away demons wandering around them. This is why most people around the world celebrate Halloween with strange costumes today. As time goes by, the meaning of Halloween has gradually changed, and it has become active and happy, and the festive meaning has become the mainstream. The idea that the dead sought body double's reincarnation was gradually abandoned and forgotten. Today, most images and pictures symbolizing Halloween, such as witches and black cats, have friendly, lovely and funny faces.
