Who can tell me about the origin of Chinese New Year, about 50-60 words?

The New Year comes from a legend. A young man named Wan Nian created a timed method to solve the problem of farming. The first day of each year was named the Spring Festival by the monarch at that time, that is, the New Year.

According to legend, there were no solar terms in ancient times, and farming depended on feelings and the harvest was not good. There is a method called wannian, which created the sundial and the time of water dripping. Wan nian told the monarch about the cycle of the sun and the moon that he had observed for a long time. The monarch was overjoyed and immediately ordered the repair of the Sun Moon Pavilion, the sundial platform and the Leaky Pot Pavilion.

One day, Wannian said to the monarch, "Hand over the children tonight, and the old year will end and the new year will begin. Please give the monarch a name for this day. "

The monarch said, "Spring is the first season of the year, and it is also a good season for farming. Let's call the first day of each year the Spring Festival! " ! "
