What's the saying about dividing eggs in spring?

Laying eggs is the solar term of the vernal equinox.

Vertical eggs at the vernal equinox, also known as vernal equinox eggs, refer to the "vertical egg game" that is popular all over the country every year on the vernal equinox. This China custom has already spread abroad and become a "world game". 4000 years ago, the ancestors of the Chinese nation began to celebrate the arrival of spring, and the saying that "the vernal equinox has arrived and the eggs are beautiful" has been passed down to this day.

This principle is based on the fact that the vernal equinox is a day divided equally between the northern and southern hemispheres. The earth's axis with an inclination of 66.5 degrees is relatively balanced with the earth's orbital plane around the sun, and the earth's magnetic field is also relatively balanced, which is very beneficial to vertical eggs.

The surface of the egg or the plane of the vertical 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.
