Why do we stand eggs upright during the Autumnal Equinox?

"When the autumnal equinox comes, the eggs will be pretty." On the spring or autumnal equinox every year, many people in many places in my country will do the "standing egg" experiment.
As early as 4,000 years ago, China had the tradition of standing eggs on the Autumnal Equinox to celebrate the arrival of autumn. In fact, standing an egg upright has nothing to do with the autumnal equinox. The point is that the center of gravity of the egg must be lower than the curve with the largest circumference in the middle of the egg. According to ancient legend, it is easiest to stand an egg upright on the Autumnal Equinox.

What is the principle behind successfully standing an egg upright during the Autumnal Equinox?

There are two main reasons why standing eggs on the Autumnal Equinox can be successful.
Reason 1:
On the day of the autumnal equinox, the day and night are equal in the northern and southern hemispheres, the Earth's axis, which is tilted at 66.5 degrees, and the orbital plane of the Earth's revolution around the sun are in a state of relative force balance, and the Earth's magnetic field is also relatively balanced, so eggs are best able to stand up.
Reason 2:
The autumnal equinox is in the middle of autumn, which is neither too cold nor too hot. People feel relaxed, their minds are sharp, their movements are agile, and it is easy to stand an egg upright successfully.

What should you pay attention to when standing eggs upright?

Tip 1: Pick eggs
First, you need to choose an egg with one end larger than the other. When standing the egg, place the larger end facing downwards. This way, the center of gravity will be lower, like a tumbler, making it easier to maintain balance.
Point 2: Find support
Find a suitable support surface and do a small experiment. Apply ink on the table and then stand an egg on the table covered with ink. You will find that the egg that can stand upright has a plane at the bottom that is difficult to see with the naked eye. Once the line of action of gravity can pass through this plane, the egg can stand up.
Point 3: Keep your hands steady
Since the position of the yolk in a raw egg will also affect the standing of the egg, the hand holding the egg should be kept as still as possible to allow the yolk to slowly settle to the bottom of the egg. This way, the center of gravity will be low enough to keep the egg balanced.
