According to astronomical theory, the direct point of the sun gradually moves south from the northern hemisphere in autumn, and after the autumnal equinox, it crosses the equator and the sun shines directly on the southern hemisphere. From the Northern Hemisphere, the angle of the Sun gradually decreases, and the gap between the length of day and night decreases. At the autumnal equinox, the day and night are equal in length.

In autumn, the distance between the Earth and the Sun gradually increases. From the plane of the zodiac, the Sun is placed on the background of Leo, Virgo, and Libra.

In the vast sky, eagles are flying vigorously, fish are swimming briskly in the clear water, and everything is striving to live a free life in the autumn light.
