Why should eggs be divided in spring?

The reasons for dividing eggs in spring are as follows:

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". The ancestors of the Chinese nation began to celebrate the arrival of spring, and the saying that "when the vernal equinox arrives, eggs look good" began to spread.

The most interesting custom on the vernal equinox is "laying eggs": choose a smooth and symmetrical egg that has just been born for four or five days and gently stand it on the table. When the vernal equinox arrives, the eggs will look good. On the occasion of the vernal equinox every year, many places in China hold "vertical egg" games or competitions.

Why should the vernal equinox erect eggs? According to historical records, the tradition of dividing eggs in spring originated in Great China 4000 years ago to celebrate the arrival of spring. In fact, standing an egg has nothing to do with the vernal equinox, just let the center of gravity of the egg be lower than the curve position of the maximum circumference in the middle of the egg. According to the ancient legend, the day of vernal equinox is the easiest day to lay eggs.

Vertical eggs actually have another meaning. Spring is coming, and everything is restless. Laying eggs is a good way to remind people to keep a good attitude and keep calm at any time.

Why did you choose to "lay eggs" at the vernal equinox? Can eggs stand up at ordinary times? What is the scientific truth of "laying eggs"?

Some people say that the "vernal equinox" is easy to stand up because the vernal equinox in the northern and southern hemispheres is as long as day and night, accounting for 66. The 5-degree inclination of the earth's axis and the orbital plane of the earth around the sun are in a state of relative balance of power, so it is easier to succeed in vertical eggs.

Others say that the "vernal equinox" coincides with the vernal equinox, the weather is lukewarm, the flowers are red and the grass is green, people are comfortable, their thinking is quick, their movements are neat, and it is also the easiest to concentrate and successfully stand the eggs.

The viewpoint in the book "Knowledge of Twenty-four Solar Terms" holds that vertical eggs have little to do with the vernal equinox. Because the egg surface is uneven, there are many protruding "hills". This mountain is very high. 03 mm or so, and the distance between "peaks" is 0. 5—0。 8 mm, according to the principle that three points determine a plane, as long as you find three "hills" and the triangle formed by these three "hills", and then let the center of gravity of the egg pass through this triangle, the egg can stand upright.

Some experts believe that vertical eggs really have nothing to do with the vernal equinox and solar terms. Because the real factor that makes an egg stand up is gravity, an egg can stand up on any day of the year. The secret of vertical eggs is mainly "steady hands and patience, a pure heart."
