It means that spring has passed half of the solar terms.

The solar term representing half a spring is the vernal equinox.

The vernal equinox is the fourth of the twenty-four solar terms, and spring is already halfway through. "Spring" means spring, and "fen" means separation, which means that spring is over half. Spring has three months, that is, 90 days. Beginning of spring is the first day, and the vernal equinox is the 45th day, which happens to be the midpoint of 90 days in spring. At the vernal equinox, the sun shines directly at the equator of the earth.

The seasons in the northern and southern hemispheres are opposite. In the northern hemisphere, it is the vernal equinox, and in the southern hemisphere, it is the autumnal equinox. The vernal equinox is an important solar term, which is of great significance in astronomy: the northern and southern hemispheres divide the day and night equally. In climate, it also has obvious characteristics. Since then, the direct position of the sun has continued to move from the equator to the northern hemisphere. The days in the northern hemisphere are getting longer and shorter, and the nights in the southern hemisphere are getting shorter and shorter.

The custom of laying eggs

Our country also has the custom of dividing eggs in spring. Celebrate the arrival of spring and try your luck. When the vernal equinox comes, eggs are beautiful. Choose a smooth and symmetrical fresh egg that has just been laid for four or five days, gently stand up and put it on the table. There are many delicious foods in this season, such as eating spring buds, Malantou and bamboo shoots, which are fresh ingredients that can only be eaten in this season.

The vernal equinox is the most beautiful season of the year. Everything grows and shines, and poets of all ages have left behind the beauty in their eyes. According to custom, farmers have a holiday on the vernal equinox. Every family should eat dumplings, and a dozen or thirty dumplings that don't contain hearts should be cooked and placed on the edge of outdoor fields with thin bamboo forks, which is called sticking sparrows' mouths so as not to destroy crops.
