Wan Nian Li is the oldest solar calendar in ancient China. It is more like a guide and an important tool for farming and daily life of Chinese people.

It’s said that in ancient times there was a young man named Wan Nian. He thought that there were natural rules for the change of seasons and climate, and wanted to find out the special rules of nature. When he climbed the mountain, he was inspired by the shadows (影子) of trees on the mountain, and made a sundial (日晷) that measures the shadow of the sun to fix the time. As time went on, he found that every more than three hundred and sixty days, the length of the day would repeat (重复) itself.

When Wan Nian knew that the emperor of the Shang Dynasty, Zu Yi was worried because of the uncertainty of time, he nominated (推荐) himself to create a calendar for the country and help all the people.

After the long-term study, Wan Nian worked out an exact calendar called Tai Yang Li. When he presented it to the emperor. Wan Nian was an old man with white hair. The emperor was very moved. To praise the achievements of Wan Nian, he named the solar calendar as Wan Nian Li. In memory of (为了纪念) Wan Nian, people called the first day of a year as “Nian”, so the Chinese New Year was born.
