Which meaningful custom is popular on the vernal equinox?

Vertical eggs are a unique custom of the vernal equinox and solar terms. At this time, the climate is equally divided day and night, the earth axis and the earth's orbital plane around the sun are in a state of relative force balance, and the earth's magnetic field is also relatively balanced, so the egg has the best standing and stability.

The game of "vertical egg" is really simple and interesting: choose a smooth and symmetrical fresh egg that has just been born for four or five days and gently stand it up on the table. Although there are many losers, there are also many winners. The vernal equinox has become the best time for vertical egg games, so there is a saying that when the vernal equinox arrives, the eggs will be beautiful.

Main points of vertical eggs at vernal equinox

Point 1: Pick eggs.

First, choose an egg with a big head and a small head. When laying eggs, the big head will face down, so the center of gravity will be lower, just like a tumbler, it is easy to keep balance.

The second point: find support.

Find a suitable supporting surface, do a small experiment, paint the table with inkpad, and then stand the egg on the inkpad. You can find that an egg that can stand has a plane at the bottom that is hard to see with the naked eye. Once the gravity line can pass through this plane, the egg can stand up.

Point 3: Keep your hands steady.

Because the position of the yolk in the raw egg will also affect the standing of the egg, the hand standing on the egg should be kept as still as possible, so that the yolk can slowly settle to the lower part of the egg, so that the center of gravity can be low enough to keep the egg balanced.
