For the autumnal equinox, the yin and yang are half and half

Therefore, the day and night are average, but the cold and the heat are calm.

The autumnal equinox is the sixteenth of the twenty-four solar terms, and the fourth solar term in autumn. On the autumnal equinox, the sun is almost directly at the equator of the earth, and day and night are equal in length all over the world. In the autumnal equinox, "divide" means "equal" and "half". In addition to the equinox of day and night, there is also a layer that means that autumn is divided equally. After the autumnal equinox, the location of direct sunlight shifts to the south, the days in the northern hemisphere are short and the nights are long, the temperature difference between day and night increases, and the temperature drops day by day.

 The characteristics of fast cooling in autumn make the "three-autumn solar term health maintenance" of autumn harvest, autumn ploughing, and autumn planting extremely busy. The autumnal equinox cotton spews out, and the tobacco leaves change from green to yellow. It is a good time to harvest. During the autumnal equinox, drought and low rain or continuous rain are the main unfavorable factors affecting the normal progress of the "Three Autumns". In particular, continuous rain will cause the crops to fall, mold, or germinate, causing serious losses. "Three Autumn" is busy, and the word "morning" is the most important thing. The timely harvest of autumn crops can avoid the hazards of early frost and continuous rain, and the early sowing of winter crops in a timely manner can strive to make full use of the pre-winter heat resources, cultivate strong seedlings to survive the winter safely, and lay the foundation for a high yield in the coming year.
