For many people Christmas is the most wonderful time of the year. One of the reasons people love it so much is that you get presents. But like presents, Christmas needs to be unwrapped so that you can understand the true meaning behind the day.

Many Chinese believe everyone in Western countries celebrate this holiday. That is not true. Christmas is an important religious holiday for Christians. December 25 represents the birthday of Jesus Christ, who Christians believe is the son of God.

Christianity (基督教) is a very popular religion in America and Europe. However, there are many other religions, too. People who celebrate those religions don’t celebrate Christmas. But during the winter season they usually have their own important holiday. That is why when talking to a foreigner it is safer to say, “ Happy holidays” instead of “Merry Christmas” because you never know his/her religious background.

The image of a fat, happy man in red---Santa Claus---has come to represent the idea of goodness and love instead of religious part or the “Christmas spirit”. Santa Claus is based on a man named Saint Nicholas who was a 4th century Greek Christian.

Saint Nicholas bought presents for children and gave them away anonymously(匿名地). This is where the idea of gift on Christmas began. But the Santa Claus didn’t exist until the 19th century when an American named Thomas Nast drew cartoons of him. So really, Santa has nothing to do with the religious holiday.

In fact, some people who celebrate Christmas don’t really care about Santa Claus.

Christmas is a special day for Christians but the ideas of being good and loving your neighbors are not limited to Christianity. So buy a gift for your friend, tell your mother you love her and have merry Christmas. I mean ,”Happy holidays!”
