Every year on March 3rd, we eat boiled eggs, but why we eat eggs is a general statement. Tracing back to the source, we find that eating eggs is actually related to three stories: the first story is that the third day of the third lunar month is the day when Han people meet their ancestors' souls, and they mourn their ancestors by eating eggs, hoping to get some aura. The second story is about the communication custom of young men and women in the March 3rd Song Market of Zhuang nationality: touching eggs. Eggs are things that dye cooked eggs into colors to convey feelings. The young man held an egg in the song market to touch the egg in the girl's hand; If the girl doesn't want to, hold the egg and don't touch it. If it's urgent, let the boy touch it. After the egg cracked, they ate eggs, which sowed the seeds of love. Others say that March 3 is an ancient festival, which evolved from the "Shangji Festival" in the Spring and Autumn Period and the Warring States Period. At that time, there was no fixed date for this festival, usually in early March. "Ji" is the stem position in the earthly branch. In the past years, there were 60 daily necessities, that is, the cross of "A, B, C, D, E, G, N and N" in the heavenly stems and the twelve characters of "Zi Chou Yin Mao Chen has not applied for the defense of the sea at noon" in the earthly branches, and sixty combinations were formed by mathematical combination to record the diary year. "Shangji" is the first day of "Shangji" in March, so it is called "Shangji", which was designated as a festival in the Han Dynasty. "It's the third day of the month, and the officials and people are all (clean) on the east running water. It's called" washing and removing dirt (illness) "(Records of Etiquette in the Later Han Dynasty). Later, the content of water banquet and outing was added. After Wei and Jin Dynasties, Shangsi Festival was changed to March 3rd, which was followed by later generations, thus becoming a festival for Han people to have a drink by the water and have a spring outing in the suburbs. On that day, there were activities such as cup-flowing, egg-flowing, jujube-flowing, begging and wearing willow rings, exploring spring, outing, eating refined rice and singing. "Flowing eggs" is an elegant game played by officials and literati, that is, putting eggs in the upper reaches of the river downstream for elegance and fun. People don't have much leisure and elegance, so it is more practical to change the flow of eggs into boiled eggs and put the eggs down the esophagus into the belly. Of course, there are other simple reasons. "On March 3rd, shepherd's purse boiled eggs." In Hunan, Hubei and other places, on the third day of the third lunar month, there is a custom of boiling eggs with shepherd's purse. It is said that eating eggs cooked with shepherd's purse will not hurt the waist and legs or the head during the year. Shepherd's shepherd's purse, also known as ground vegetable, nursing grass and chicken heart vegetable, can be used as medicine for its roots, flowers and seeds. "Poetry, Gu Feng, Gu Feng" says, "Who says tea is bitter, it is as sweet as water". Cruciferae, an annual herb, has mild sexual preference and strong cold tolerance. Wild in the fields. The whole grass contains Capsaicin, alkaloids, amino acids, flavonoids and other components. Young plants can be used as vegetables, and whole grass with flowers and fruits can be used as medicine. It is cool in nature and sweet in taste, and has the functions of cooling blood and stopping bleeding. It is mainly used for hematemesis, hematuria, metrorrhagia and dysentery. Recently used to treat nephritis, chyluria and other diseases. Some nutrition experts said that although "eating cauliflower and boiling eggs on March 3" is a traditional custom, it was mainly used to prevent spring epidemic in ancient times, and its scientific nature remains to be verified. However, from a nutritional point of view, although the ground vegetables are wild vegetables, they are rich in nutrients, which contain a lot of carotene, vitamin B and vitamin C, and the content of calcium and iron is also relatively high. These nutrients are beneficial to human health. In addition, the protein content of eggs is high, and lecithin and vitamin A are also rich, so two kinds of nutritious foods are naturally good for the body.
