China people's food culture actually has its most basic reasons. Let's not talk about eating eggs on March 3rd, zongzi, duck eggs and realgar wine on Dragon Boat Festival, moon cakes on Mid-Autumn Festival, rice on Spring Festival and Yuanxiao on Lantern Festival. There are two points to note here. First, these festivals are basically evenly distributed, after a period of time. Second, you can't do without something to eat. This is because in China's thousands of years of history, most years are material. That is to say, nutrition is usually insufficient. Long-term malnutrition will affect survival, so we need a good reason to eat something that we usually can't bear to eat. In addition, the third day of the third lunar month is the peak period for chickens to lay eggs, and there are many eggs, which are not expensive to buy. Therefore, we should "expand domestic demand" and eat some ourselves, killing two birds with one stone.

The real origin of cold food and chicken (egg) fighting in Tomb-Sweeping Day still owes to the custom of forbidding fire in some areas in the pre-Qin period. Cold food has been banned for many days, and boiled eggs are undoubtedly the best food reserve to survive this period. Moreover, the Qingming outing and boiled eggs are also portable foods. Pre-collision peeling will inevitably arouse children's interest in colliding with each other.

If we want to explore the symbolic significance of Tomb-Sweeping Day's eating eggs against eggs, we should also include people's awe and belief in life and fertility. In the ancient culture of China, the egg was a symbol of fertility and life. Legend has it that the epoch-making Pangu was conceived in an egg in which "heaven and earth are chaotic like a chicken, and Pangu was born" (Ivan Lei Ju). The ancestor of Shang Dynasty agreed that "a bird dropped its egg, a butterfly took it and swallowed it, and it was born of pregnancy" (Historical Records), and the great cause of the ancestor of Qin Dynasty was also "a bird conceived its egg and a woman swallowed it" to conceive (Historical Records). This is a folk custom. When a woman gives birth to a child, she brings good news to her neighbors and eight families. Aren't they eggs, too? Tomb-sweeping in Qingming Festival, among them, don't you also have the life consciousness of being cautious to the end? Spring is the season of life, and many folk customs coincide in the deep meaning of life.

It is said that eating eggs cooked at this time will not cause headaches for a year. How did this custom come down? Legend has it that the ancient Xiaogan area was a part of Yunmengze, a water town, and people made a living by fishing. Because people blow the lake breeze in the lake every day, they have headaches. One day, Shennong, who had tasted all kinds of herbs, passed Yunmengze and saw someone rolling on the lake beach because of a headache. Shennong sympathized with them and looked for herbs everywhere to treat their headaches. But nothing works. On the third day of March, Shennong picked up some wild eggs from the mountain, dug a handful of vegetables and brought them to the boat to cook for people to satisfy their hunger. People will suddenly feel headache after eating rice and scrambled eggs. Later, on the third day of March, I ate and cooked.

Eggs have become a custom and have continued to this day.

Eating eggs in Tomb-Sweeping Day is as important as eating zongzi on Dragon Boat Festival. Saving eggs can be roughly divided into two types, one is "painting eggs" and the other is "carving eggs". The former is edible, while the latter is just for enjoyment. However, there is also a saying that when sweeping the grave, the boiled eggs are broken on the tombstone and the eggshells are thrown on the grave, which symbolizes "shelling" and indicates a new life. I hope future generations will get there first.
