The Spring Festival in China
Every year there is a Spring Festival in China. Usually it is held in January or February. Of all our festivals, the Spring Festival is the most important. So before it comes, everyone has to decorate them. The old folk says that everything must be new and clean for the Spring Festival celebrations so that the new year will bring happiness and good luck. We also buy pork, beef, chicken, fruit and many other things. Parents buy new clothes for their children and children may also buy presents for their parents.
The celebration begins on the eve of the lunar new year, and we put up some New year pictures. On the Festival eve, all the family members come back to their hometown. No matter how far away from home a person is, he will always try to get home in time for this big dinner. We often make a special kind of food called “dumplings”. It means “come together”. When we’re enjoying the meal, we give each other the best wishes for the coming year. We sing, dance and play cards.
On the first day of the holiday, we usually stay at home. We get up fairly early and, first thing, exchange New Year greetings. This is a happy moment for the children; they can get some pocket money. And then we shot off firecrackers and fireworks. We enjoy ourselves very much.
On the second and the third days, we go visiting relatives and friends. We sit around chatting and eating sweets and New Year Cakes and all kinds of delicacies. Each family prepares something special. Sometimes we would see some lion and dragon dancing.
The celebration lasts about 15 days. The 15th night of the first moon in called the Lantern Festival. This is the day when we young people go out to enjoy ourselves, and sometimes we dance folk dances far into the night.
