What solar term is better for laying eggs?

"Vernal Equinox" solar terms In ancient legends, the vernal equinox is the easiest day to lay eggs. According to historical records, the tradition of laying eggs at the vernal equinox originated in China 4000 years ago to celebrate the arrival of spring. The saying that "the vernal equinox is here and the eggs are beautiful" has been passed down to this day. On this day, many places in our country will hold egg laying competitions.

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. The eggs that stand up are very beautiful.

According to experience, it should be "the spring equinox lays eggs vertically": the surface of eggs is actually uneven, with many protruding "hills". The height of the "hills" is about 0.03 mm, and the distance between peaks is 0.5 mm to 0.8 mm. According to the principle of determining a plane by three points, as long as three suitable "hills" are found, the eggs can be erected.

First, on the vernal equinox, the northern and southern hemispheres are divided equally day and night. The earth's axis is inclined at 66.5 degrees, which is in a relatively balanced state with the earth's orbital plane around the sun, and the earth's magnetic field is also relatively balanced, so the egg stands best.

Secondly, the vernal equinox is in the middle of spring, neither too cold nor too hot. People are comfortable, quick-thinking and easy to succeed in laying eggs.

However, some experts believe that this is a purely technical issue and has nothing to do with the vernal equinox. Astronomical experts say that eggs can be erected on any day of the year, and a stable egg can last for more than ten days without external interference.
