What does the vernal equinox mean?
The vernal equinox is the fourth of the 24 solar terms. This is an important agricultural season. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons. The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the vernal equinox, day and night on the earth are equal. Astronomically speaking, the "vernal equinox" refers to the position of the sun between 0 degrees and 15 degrees of the yellow meridian. On the day of the "vernal equinox", the sun shines directly at the equator of the earth, so from this day on, the sun will slowly move northward, so the "vernal equinox" is also called the rising equinox. In ancient China, it was also called "Equal Day and Night" and "Midspring Night". There is a folk proverb called "Equinox in Spring and Equinox in Autumn".
"Spring and Autumn Stories Yin and Yang in and out" said: "The vernal equinox, Yin and Yang are also half-phase, so it is cold and summer day and night."
According to the "Twenty-four solar terms": "In mid-February, it is divided into half, which is half of ninety days, so it is called minutes." Another article, Spring and Autumn Stories, Yin and Yang in and out, said: "At the vernal equinox, Yin and Yang are also half-phase, so day and night are cold and summer." There is a "Li Mingshi Yi" cloud: "The dividing line, the point where Huangchi intersects, the sun is here, and the day and night are equally divided." Therefore, the significance of the vernal equinox, first, refers to the equal division of day and night, each of which is 12 hours; Second, in ancient times, it was spring from beginning of spring to long summer, and the vernal equinox happened to be in the three months of spring, and spring was equally divided.
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 vernal equinox is recorded in the ancient calendar of China: "Three days before the vernal equinox, the sun entered the equator".
