The custom of eating vertical eggs at the autumnal equinox is usually to use eggs or duck eggs.
Eggs.
Because eggs have auspicious meanings both in meaning and name. "Thirty-five Calendars" records: "Heaven and earth are chaotic like chickens, and Pangu was born in them, eight thousand years old, and heaven and earth are open." It is this hazy primitive worship of "egg" that makes the universe like an egg, indicating that chicken is a very auspicious symbol.
In addition, it is said that Nu Wa Niangniang first created six kinds of animals (including chickens) and finally created human beings. It can be seen that chickens were regarded as spiritual birds in ancient culture.
Also, cooked eggs are more unbearable than raw eggs. Because the center of gravity of boiled eggs has been determined, if the center of gravity does not fall on the supporting surface of eggs, how can it stand upright? The surface or desktop of an egg is uneven. As long as there are any three supporting points, a supporting surface can be formed. As long as the center of gravity of the egg falls on this supporting surface, the egg can stand up.
However, it is difficult to find the center of gravity because the surface of the egg is curved and the supporting surface is relatively small.

1, and the average daily temperature in autumn is below 22℃. At the autumnal equinox, the Yangtze River basin and its vast northern area have entered autumn, and the daily average temperature has dropped below 22℃. The cold air mass in the north began to have some influence. In most areas, the rainy season has just ended, with a cool breeze blowing gently, the sky is high and the clouds are light in Wan Liqing, the air is crisp in autumn, the sweet-scented osmanthus is fragrant, the crab is fat and the chrysanthemum is yellow, and the autumn equinox is a beautiful and pleasant season.
2, the ground heat loss is more, and the temperature drops rapidly. After the autumnal equinox, the direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, but the ground lost more heat and the temperature dropped significantly. Agricultural proverbs say: "An autumn rain is a cold", "The white dew is divided into autumn nights, and one night is cold". "In August, the wild goose gate opens, and the foot of the wild goose is frosty." It is not surprising that the temperature in Northeast China drops early and frost appears at the autumnal equinox.
