What is the meaning of the Autumnal Equinox?

The ancient Chinese book "Spring and Autumn Annals" says: "The autumnal equinox is when yin and yang are equal, so the day and night are equal and the cold and heat are balanced.
The "fen" in "Autumnal Equinox" means "half". "Autumnal Equinox" means that according to the ancient Chinese method of dividing the seasons with the beginning of spring, summer, autumn and winter, the autumnal equinox is in the middle of the 90 days of autumn, dividing the autumn season equally.
The meaning of the Autumnal Equinox in "Collected Explanations of the 72 Solar Terms in the Lunar Calendar": "Mid-August...see the Spring Equinox for the explanation." "Fen" means the time when day and night are equal. Just like the spring equinox, the sun shines directly on the earth's equator, and the day and night are equal.
After that, the position of direct sunlight moved further south, the days became shorter and the nights longer in the Northern Hemisphere, and the temperature dropped, which had universal significance across the country.
After the autumnal equinox, the days become shorter and the nights longer in all parts of the Northern Hemisphere, while the days become longer and the nights shorter in all parts of the Southern Hemisphere.
From the winter solstice, the days become longer, but from the vernal equinox, the days become longer than the nights. From the summer solstice, the days become shorter, but from the autumnal equinox, the days become shorter than the nights.
"Autumnal Equinox" is also the "Chinese Farmers' Harvest Festival".
The Autumnal Equinox is the sixteenth solar term in the “Twenty-Four Solar Terms” of the Chinese lunar calendar, which is exactly half of the 90 days from “Beginning of Autumn” to “Frost Descent”. During the autumnal equinox, the weather is sunny and windy, the osmanthus is fragrant, the crabs are plump and the chrysanthemums are yellow. It is a scene of a bumper harvest with fragrant fruits and full granaries.
Traditionally, the Autumnal Equinox is not only the end of autumn harvest and winter storage, but also the starting point of spring ploughing and summer planting. As an agricultural proverb in North my country says: "White Dew comes early, Cold Dew comes late, so the Autumnal Equinox is the right time to plant wheat."
Therefore, the country has established the autumnal equinox every year as the "Chinese Farmers' Harvest Festival", which is not only a tribute and inheritance to the traditional "Twenty-Four Solar Terms", the crystallization of ancient wisdom, but also reflects that contemporary Chinese people are aware of the changes in nature, comply with natural laws and adapt to sustainable ecological development.
