Is the vertical egg a vernal equinox or an autumn equinox?

The autumnal equinox lays eggs vertically

As early as 4,000 years ago, China had the tradition of dividing eggs in autumn to celebrate the arrival of autumn. In fact, the vertical egg has nothing to do with the autumnal equinox, but the center of gravity of the egg must be lower than the curve position of the maximum circumference in the middle of the egg.

Principle: First, the autumnal equinox is the day when the northern and southern hemispheres are equally divided day and night. The inclination of the earth axis of 66.5 degrees is in a relatively balanced state with the orbital plane of the Earth Day, which is conducive to vertical eggs; Second, the autumnal equinox is in the middle of autumn. It's lukewarm, colorful and green. People are comfortable, quick-thinking and easy to succeed in laying eggs.

Key points of vertical eggs in autumn equinox:

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.

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.

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.
