What does the autumnal equinox mean?

The autumnal equinox solar terms have two meanings:

1, the climate changed from hot to cool. According to the division of seasons in ancient China, which started with beginning of spring, Changxia, beginning of autumn and beginning of winter, the autumnal equinox is divided into 90 days in autumn and divided equally in autumn.

2. The time of day and night is equal. On this day, the sun reached the longitude 180 degrees, and directly hit the equator of the earth. Therefore, in most parts of the world, 24 hours are divided equally between day and night, each being 12 hours. After the autumnal equinox, the direct point of the sun began to enter the southern hemisphere from the equator, and the northern hemisphere began to have shorter days and longer nights, and the day began to be shorter than the night in a day.
