From ancient Ireland. The story is about a child named Jack who loves pranks. One day after Jack died, he couldn't go to heaven because he did bad things, so he went to hell. But in hell, he was stubborn and tricked the devil into going up the tree. Then he carved a cross on the tree stump to frighten the devil and make him dare not come down. Then Jack made three rules with the devil and asked the devil to promise to cast a spell and let Jack never commit a crime as a condition to let him go down the tree. The hell master was very angry and drove Jack out. He only wandered around the world with a turnip lamp and hid in when he met human beings. Gradually, Jack's behavior was forgiven by people, and children followed suit on Halloween. The ancient turnip lamp evolved to today, and jack-o-lantern was made of pumpkin. It is said that soon after the Irish arrived in the United States, they found that pumpkins were better than turnips in terms of origin and carving, so pumpkins became very popular in Halloween.
