Beginning of spring is an activity of solar terms.

Cattle raising is a very important production tool in ancient agricultural production, which almost directly determines the success or failure of a family's agricultural production, so everyone hopes that their cattle can work hard and make contributions to their farmers. Everyone cherishes scalpers, but in order to spur them, people make them look like scalpers with materials and then symbolically whip them, hoping to make them work hard in this way. This is "spring cow". At first, spring cattle were made of clay. After breaking them, people rushed to grab the scattered clods, hoping to bring blessings.
