the legend say(或者the old story tells),santa clous will come with loaded christmas gift sled and all these gift is going to be given to the child who behaves well this year.he will quitely come from the chimney and put the toy inside the socks that is hooked on the bed.because of this children will put colourful socks hooked on the bed,and put hot milk nearby for the santa clous to drink so they can get a big gift.the next day the childrens will rush to open the gift to see what they get.愿樓主采納.
