The jack-o-lantern is a symbol to celebrate Halloween. Legend has it that a man named Jack was so stingy that he couldn't go to heaven after death, and because he made fun of the devil, he couldn't go to hell, so he had to wander around with lanterns until the day of judgment. In order to scare away these wandering souls on Halloween, people carve terrible faces with turnips, beets or potatoes to represent Jack holding lanterns, which is the origin of pumpkin lanterns.

Night originated from celebrations related to evil spirits, so witches, ghosts, goblins and skeletons riding brooms are all symbols of Halloween. Bats, owls and other nocturnal animals are also common symbols of Halloween. At first, these animals were very scary because people thought they could communicate with the ghosts of the dead. Black cats are also symbols of Halloween, and they also have certain religious origins.

Legend has it that there was a man named Stingy Jack in Ireland who invited the devil to drink one day. Because he had no money to pay the bill after drinking, he persuaded the devil to turn into sixpence to pay for the drink, but Jack did not use it to pay for it. Instead, he used a piece of silver paper to stop the devil from coming out. Later, the devil promised Jack not to scare him for a whole year, and Jack let the devil out.
