In Western countries, every October 31st, there is a Halloween, the dictionary is interpreted as "The eve of All Saints'Day", Chinese translation: Halloween night.
With regard to Halloween, people have more or less perceptual cognition: knowing that during Halloween, many public places and even homes, there will be a lot of decoration, such as all kinds of ghosts, pumpkin lights, and black cats. The witch's broom and the like; the children will wear different Halloween costumes every year, carrying the pumpkin lanterns to go door-to-door to discuss sugar, saying "trick or treak".
