How did the vernal equinox come from?

The vernal equinox is the fourth solar term in the "24 solar terms". "The vernal equinox, Yin and Yang. So it's hot and cold day and night. " The so-called vernal equinox is the midpoint of 90 days in spring. Every year on March 20th of the Gregorian calendar, when the sun is at 0 (vernal equinox) of the Huangjing.

The vernal equinox is a new year in Iran, Turkey, Afghanistan, Uzbekistan and other countries, with a history of 3,000 years.

First of all, the origin of the vernal equinox

In ancient China, the vernal equinox was divided into three periods: "First, waiting for the arrival of birds; Second, wait for Lei Nai to make a sound; Third, wait for electricity. " In other words, after the vernal equinox, swallows will fly from the south, and when it rains, the sky will thunder and lightning. The corresponding phenological phenomenon in the ancient Yellow River basin is "the arrival of a mysterious bird, the thunder and the electricity" (see "Nongsang Tongzhi"). At this time, the overwintering crops in most parts of China entered the spring growth stage. A farmer's proverb in central China says, "Wheat rises at the vernal equinox, which is a worthwhile moment."

The vernal equinox is also a traditional festival. In the Zhou dynasty, there was a ceremony to worship the sun at the vernal equinox. Book of Rites: "Altar." Confucius' Ying Da Shu: "Also called the vernal equinox." This custom has been handed down from generation to generation.

Step 2 send spring cattle

Another custom of the vernal equinox is to send photos of spring cattle door to door. Spring cattle pictures are printed on red paper or yellow paper, with lunar solar terms all the year round, plus farmers' farming patterns. The people who send pictures are folk singers with good temper, mainly talking about auspicious words about spring ploughing and not going against the farming season. Although it comes out casually, every sentence should have a taste. Commonly known as "spring", spring people are called "spring officials".
