Pumpkins are used to make scary lanterns on Halloween in the west. There is an old western legend, which records a little boy named Jack. He was very naughty and tricked the devil into a tree, so he was punished by the devil, and his undead could only wander between chaos. In order to see the road clearly, Jack had to hollow out the pumpkin, put candles in it, and make a simple lantern with lighting along the way. Just because the pumpkin is short and fat, you can remove the heart of the pumpkin, there is a lot of room for candles, then hollow out the skin and a lantern will come out.
