Santa Claus, nicknamed Saint Nick, Kris Kringle, Father Christmas or Santa (Irish English), is a mysterious figure who quietly gives gifts to children on Christmas Eve, and is one of the representative roles of the festival theme. He is generally regarded as a derivative image of the Christian saint Saint Nicholas.
Legend has it that every night on February 24th/Kloc-0, 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 at the good boy's bedside or pile them under the Christmas tree beside the fireplace. He is busy making gifts and supervising the 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 with a red hat, a big white beard, a red cotton coat, red boots and a big bag with gifts. Because he always appears on Christmas Eve to distribute gifts, he is used to calling him "Santa Claus".
