1, Da Chun is the common name of beginning of spring.

Beginning of spring is the first of the 24 solar terms and one of the traditional festivals in China. As early as the Zhou Dynasty, the Emperor of Zhou would lead three ministers and nine ministers to the suburbs to celebrate the Spring Festival and pray for good weather and abundant crops this year. During the Tang and Song Dynasties, we also joined the activities of shooting spring cattle and sending Koharu cattle to express our hope for a bumper harvest. The spring cattle here are made of mud, and the mulberry trees are made of skeletons. The requirement for soil is to get soil in winter to the future. The size of a spring cow is four feet high and eight feet long. The whip used to beat spring cattle must be red and green. This is called spring bull shooting, and the purpose is to pray for a bumper harvest.

The practice of beating spring cattle originated from the palace. It is said that on this day, in order to celebrate the beginning of spring, the royal family will break the mud cows made in advance in front of the palace to celebrate. It is said that Duke Zhou was the first to make mud cows with spring mud, and it has been recorded in the literature that "Duke Zhou only made the beginning of spring mud cows".
