As the saying goes, "Eat the egg on the first day of summer, and do not resist summer in hot days." A long time ago, every summer day, a plague god would spread the plague, but anyone who caught the plague, especially children, would experience physical fatigue, weakness in the limbs, and loss of appetite. In the end, with the help of Mother Nuwa, it was said that this kind of plague was called "Resistance and Propulsion", and that only by eating boiled chicken, duck and goose eggs on the first day of summer, and then hanging an egg on children's chests, "Resistance and Propulsion" could be avoided. Therefore, the custom of eating eggs on the day of summer has been continued until today.

There are three meanings of eating eggs in the summer, the first is because the shape of the egg is round, symbolizing the success of life, eating eggs in the summer can pray for peace in the summer. The second is that eating eggs on the first day of summer can prevent bitter summer symptoms such as loss of appetite, tiredness and limb weakness, and emaciation, which are common in summer days. The third meaning is that eating in the summer is the most complementary, eating an egg is equivalent to eating a chicken. After the beginning of summer, farming starts to get busy and people get tired easily. Eating eggs is to replenish physical strength. In the past, when living conditions were not so good, eating an egg at the beginning of summer was not only a treat before hard labor, but also an expectation of peace and a good harvest.
