The Spring Festival comes on the first day of Chinese lunar calendar and lasts for almost half of a month. Its origin is too old to be traced. Several explanations are hanging around. All agree, however, that the word Nian, which in modern Chinese solely means "year", was originally the name of a monster beast that started to prey on people the night before the beginning of a new year.

One legend goes that the beast Nian had a very big mouth that would swallow a great many people with one bite. People were very scared. One day, an old man came to their rescue, offering to subdue Nian. To Nian he said, "I hear say that you are very capable, but can you swallow the other beasts of prey on earth instead of people who are by no means of your worthy opponents?" So, it did swallow many of the beasts of prey on earth that also harrassed people and their domestic animals from time to time.

After that, the old man disappeared riding the beast Nian. He turned out to be an immortal god. Now that Nian is gone and other beasts of prey are also scared into forests, people begin to enjoy their peaceful life. Before the old man left, he had told people to put up red paper decorations on their windows and doors at each year's end to scare away Nian in case it sneaked back again, because red is the color the beast feared the most.So after that, people use red color and fireworks or firecrackers to drive away "nian” every year. As a result, the custom of using red color and setting off fireworks remains.

To celebrate the great victory people of every family would paste red paper couplets on the door panels, light red lanterns, beat gongs and drums, let off fireworks and firecrackers all through the night. Early next morning they would greet each other happily. Generation after generation, the day of Spring Festival came into being.

From then on, the tradition of observing the conquest of Nian is carried on from generation to generation. The term "Guo Nian", which may mean "Survive the Nian" becomes today "Celebrate the (New) Year" as the word "guo" in Chinese having both the meaning of "pass-over" and "observe". The custom of putting up red paper and firing fire-crackers to scare away Nian should it have a chance to run loose is still around. However, people today have long forgotten why they are doing all this, except that they feel the color and the sound add to the excitement of the celebration.

It is said that the custom of Spring Festival started in when people offered sacrifice to ancestors in the last month of the lunar calendar. At that time, people prepared the sacrifice by doing thorough cleaning, having bathes and so on. Later, people began to worship different deities as well on that day. It is the time that almost all the farm works were done and people have free time. The sacrificing time changed according to the farming schedule and was not fixed until Han Dynasty (202BC-220AD). The customs of worshipping deities and ancestors remains even though the ceremonies are not as grand as before. It is also the time that spring is coming, so people held all kinds of ceremonies to welcome the spring.
