What does the ancient vernal equinox mean?

In ancient times, the equinox meant that spring was already halfway through.

1, "vernal equinox" literally means half, that is, one divides into two, so "vernal equinox" can not only mean equal day and night, balance between cold and summer, but also mean equal spring.

2. In ancient times, people called the three months from beginning of spring to the long summer as spring, and the vernal equinox was just in the middle of these three months, so the vernal equinox meant that spring was already halfway through.

In addition, the vernal equinox was also called "Japan-China", "Day and Night Equinox" and "Midspring Moon" in ancient times.

4. Twenty-four solar terms are the crystallization of China's wisdom in farming times, and people have long used it to guide agricultural production. Even in modern times with advanced meteorology, the 24 solar terms can play a role.

5. As the saying goes, "The vernal equinox of wheat rises, and the fertilizer and water should follow closely." Spring has already passed halfway, and the busy spring has begun. Let's sow new hope for next year!

Characteristics of vernal equinox:

1 and March 2 1 are the vernal equinox among the 24 solar terms, and they are also one of the traditional festivals in China. There are customs such as flying kites, laying eggs, offering sacrifices, eating spring vegetables and sending spring cattle.

2. Through the geography knowledge learned in middle school, we can know that after the winter solstice, the direct point of the sun will move northward, and at the vernal equinox, it will directly hit the equator of the earth, and the length of day and night in the northern hemisphere and the southern hemisphere is almost equal. After that, the days in the northern hemisphere will be longer and longer, and the days in the southern hemisphere will be shorter and shorter.

3. The climate characteristic of the spring equinox solar terms is sunny and warm weather. Except the Qinghai-Tibet Plateau, Northeast China, Northwest China and North China, most parts of China have entered meteorological spring, so the vernal equinox is also the busiest time for spring ploughing.
