Santa Claus is an old man in red clothes and he wears a red hat. He has long white beard(胡子). He comes from the north on a reindeer(驯鹿) sleigh(雪橇) every Christmas Day. He went into people's houses and put presents into children's socks. So in Western countries, parents put presents into their children's socks on Christmas Eve. The next day, the first thing for children is to find the presents from Santa Claus.
