This is a custom in China. On this day in beginning of spring, people have the custom of eating spring cakes. For example, "Guanzhong Ji" written by Pan Yue in Jin Dynasty records: "(Tang people) make spring cakes in early spring and eat them wrapped in Artemisia annua, leeks and Polygonum hydropiper buds." People in the Tang Dynasty also said in the Collection of Comments on Chen: "beginning of spring is full of spring cakes, which is called" biting spring ".

In the past, the custom of eating spring cakes at the beginning of spring every day was not only popular among the people, but also often presented to ministers as holiday food in the palace. For example, Chen Yuanliang's "Guang Ji at the Age of Years" also said: "The day before beginning of spring, Ouchi ate spring cakes, and his ministers drank alcohol. The lettuce in the dish is decorated with radish and placed in the middle. " In fact, the custom of eating spring cakes in beginning of spring originated in the Tang Dynasty, which is also called "biting spring". Because at the beginning of spring, when spring returned to the earth, everything revived and all kinds of vegetables sprouted, people began to try very early. The ancients wrapped seasonal vegetables in dough, rolled them into rolls, steamed them or fried them, and named them spring cakes, which symbolized the bumper harvest of grains and the symbol of spring, and gave them to each other to welcome the spring.
