The solar terms at the beginning of a year's agriculture are

The solar term of a year's farming season is beginning of spring. Beginning of spring is the first of the 24 solar terms. Standing means "start"; Spring represents warmth and growth. Twenty-four solar terms were originally formulated on the basis of "variable stars". When the bucket handle of the Big Dipper points to the shade, it is beginning of spring. At present, solar terms are determined according to the longitude of the sun. When the sun reaches longitude 3 15, it will be the beginning of spring, and the festival will be held from February 3 to 5 of the Gregorian calendar every year. Beginning of spring marks the end of the winter when everything is hidden and begins to enter the warm and sunny spring.

Twenty-four solar terms are the product of ancient farming civilization, which occupies an extremely important position in China's traditional farming society. Before the Qin and Han Dynasties, the customs and cultures of the north and the south were different. In some places, the first day of the lunar calendar is not the first day of the lunar calendar, but beginning of spring and beginning of spring have 24 solar terms. The beginning of New Year's Eve is of great significance to the traditional farming society. The main celebration activities, such as ancestor worship, praying for a happy New Year, exorcising evil spirits and avoiding disasters, getting rid of the old and rejuvenating the new, and welcoming the New Year, are all held around the Spring Festival. This series of festivals not only constitutes the framework of the New Year's Eve Festival in later generations, but also retains its folk function to this day.
