Folk activities of solar terms for laying eggs in beginning of spring.

The vernal equinox egg, also called the vernal equinox vertical egg, refers to the "vertical egg game" which is popular among people all over the country on the day of vernal equinox every year. 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 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 eggs that stand up are very beautiful. According to experience, we should "separate eggs in spring": according to the principle of three points and one side, as long as we find three suitable "mountain" fulcrums, we can make the eggs stand upright.

Requirements for vertical eggs:

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.

Step 2 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.

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.
