What is the meaning of the 24 solar terms and the vernal equinox?

The meaning of "Spring Equinox" is half, which means day and night are equally divided, and the cold and heat are balanced.

The vernal equinox refers to the position of the sun between 0° and 15° of longitude in the time cycle, which is approximately between March 20 and April 5.

On the vernal equinox, the sun shines almost directly at the Earth's equator, and day and night are almost equal in length all over the world.

In addition, the vernal equinox also means the equal division of spring. Traditionally, spring is from the beginning of spring to the beginning of summer, and the vernal equinox is in the middle of the three months of spring.

The vernal equinox was also called the "noonday", "day and night equinox" and "mid-spring moon" in ancient times.

During the Spring Equinox, there is a Chinese folk custom of women and children competing to fly kites. There is also a folk proverb that "if you eat shepherd's purse, all vegetables will not be fresh."

In the Lingnan area, there is a custom of eating spring vegetables on the Spring Equinox.

There is also a folk saying in China that "when the spring equinox arrives, the eggs will look pretty".

Every spring equinox, tens of millions of people around the world experiment with the "egg-erector" game.
