Is an autumnal equinox vertical egg? What does the autumnal equinox mean?

There are 24 solar terms in China, and the autumnal equinox solar term is the autumn solar term. During the autumnal equinox, the weather gradually turns cold, and there are many customs in the autumnal equinox. So is the autumnal equinox vertical egg a raw egg? What does the autumnal equinox mean? Let's learn about the old almanac together!

Is the autumnal equinox vertical egg a raw egg? Yes, raw eggs stand up easily.

Cooked eggs are more unbearable than raw eggs. Because the center of gravity of the boiled egg has been determined, how can the egg stand upright if the center of gravity does not fall on the supporting surface of the egg? 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 within this supporting surface, the egg can stand up. However, because the surface of the egg is curved and the supporting surface is relatively small, it is difficult to find the center of gravity. But one thing will not change: the higher the center of gravity, the more difficult it is to balance; The lower the center of gravity, the easier it is to stand upright. This is why experts who study vertical eggs come to the conclusion that when raw eggs are shaken and the yolk sinks, they will be more vertical.

What does the autumnal equinox mean?

The ancient Chinese book "Story of the Spring and Autumn Period, Yin and Yang in and out" says: "At the autumnal equinox, Yin and Yang are also half-phase, so day and night are cold and hot." The autumnal equinox means "half". "Autumnal Equinox" refers to the seasonal division method in ancient China, which started with beginning of spring, Changxia, beginning of autumn and beginning of winter. The autumnal equinox lived in autumn for 90 days and divided the autumn equally.

The meaning of the "twenty-four solar terms" in the autumnal equinox: "See the vernal equinox in mid-August". "Minute" means to distribute day and night equally. Just like the vernal equinox, the sun shines directly at the equator of the earth, and day and night are equal. Since then, the position of direct sunlight has moved further south, and the days in the northern hemisphere have gradually shortened, the nights have become longer and the temperature has dropped, which is of universal significance throughout the country. After the autumnal equinox, the days in the northern hemisphere are getting shorter and shorter, and the nights in the southern hemisphere are getting longer and shorter. From the winter solstice, the days become longer and longer, but from the vernal equinox, the days are longer than the nights. From the summer solstice, the days become shorter and shorter, but from the autumn equinox, the days are shorter than the nights.
