Santa Claus is a figure in western myths and legends. According to legend, Santa Claus quietly gives presents to children on Christmas Eve in the west, which is the birthday ceremony of Jesus Christ, that is, one of the representative roles of western Christmas. He is generally regarded as a derivative image of Christian Saint Nicholas. The origin of Santa Claus is related to a kind of red and white mushroom called poisonous fly umbrella [1].

Legend has it that every night on February 24th of 12, a mysterious man will fly in the sky in a sleigh pulled by nine reindeer, enter the house from house to house through the chimney, and then secretly put gifts in socks beside the child's bed or pile them under the Christmas tree beside the fireplace. He is busy making gifts and monitoring children's behavior at other times of the year.

Although no one has really seen the mysterious man, people will dress up as him to give gifts to their children. He is usually described as an old man, wearing a red hat, a white beard, a red cotton coat, black boots and carrying a big bag full of gifts. Because he always appears on Christmas Eve to distribute gifts, people are used to calling him "Santa Claus".
