Why can eggs stand upright on the vernal equinox?
Among the customs of the vernal equinox, "laying eggs" and "eating spring vegetables" are more interesting.
"Vertical Egg" is a popular game: take a fresh egg, try it several times, and finally try to stand it on the table. This is success.
In the past, people thought that eggs were related to the growth and reproduction of everything in spring, and the vernal equinox was equally divided day and night, which was more conducive to finding a balance point to stand eggs, so the vernal equinox had such a custom.
In addition, on this day, for the sake of fairness, the ancients also proofread the measuring instruments.
In ancient China, the vernal equinox was divided into three stages: "One stage is the arrival of mysterious birds; Second, wait for Lei Nai to make a sound; Third, wait for electricity. " The "blackbird" here refers to the swallow. When the vernal equinox comes, swallows begin to fly back from the south. When it rains, the sky will thunder and lightning.
Rain at the vernal equinox is a good year;
In fact, the vernal equinox had many nicknames in ancient times, such as "Japan-China", "Day and Night Equinox" and "Midspring Moon".
According to "Li Mingshi Yi", "The dividing line is the point where Huangchi meets, and the sun runs here, and the day and night are equally divided." Because it is closely related to farming activities, the people also left a saying that "there is no rain in the vernal equinox" and "it is a good year to have rain in the vernal equinox".
Besides diet and games, there are many other customs around the characteristics of the vernal equinox. However, with the passage of time, some folk customs and sacrificial activities originally belonging to the vernal equinox have gradually merged into other important activities related to spring.
Among the 24 solar terms, the vernal equinox is not as important as the winter solstice and Tomb-Sweeping Day, but it is also a key time node, which is of great significance to agricultural production.
