On this day, the Sun reaches 180 degrees of ecliptic longitude and shines directly at the Earth's equator, so the 24-hour day and night are evenly divided into 12 hours each in most parts of the world.

Because the autumnal equinox solar term is exactly the middle of autumn, it divides autumn equally. According to the work "Seventy-two Candidate Explanations of the Lunar Order": "The spring equinox is seen in mid-August".

Spring and Autumn Dew, Yin and Yang in and Out of the Hall and Yang in and Out of the Upper and Lower Chapters" said: "The autumn equinox, the yin and yang are half of each other, so the day and night are even, and the cold and summer are even." "In ancient China, the autumn equinox was divided into three phases:

Wait for the thunder to start to stop; secondly, stinging insect blank households; Three wait for the water to start drying". The ancients believed that thunder was made because of the strong yang energy, and after the autumn equinox, the yin energy began to flourish, so it no longer thundered. Autumn Equinox Three Zodiac Meaning:

One wait: Thunder began to close Bao said: Thunder, the sound in the sun in February, the sound in the yin in August, and everything will follow in the ground.

The ancients believed that thunder was made because of the strong yang energy, and after the autumn equinox, the yin energy began to flourish, so it no longer thundered. Therefore, the thunder is not only the end of the summer, but also the beginning of the autumn cold, but also a sign that everything is beginning to decay, and the weather is gradually cold and cold. Second Candidate:

The "Book of Rites" notes that the billet is beneficial to the household of the stinging hole, making the bright place slightly smaller, and it is very cold, and it is also congested. As the weather gets colder, the insects begin to hide in their burrows, and the holes are sealed with fine soil to prevent the cold from entering.

Autumn, which means "collection", begins to store food for animals that have survived the winter. Human beings pay attention to the autumn harvest, firstly, to comfort the joy of spring ploughing and harvest, and secondly, to prepare for the next year's food. Conform to the changes in the solar terms, the way to do things at this time should not be "full" and should be "collected", and should be retracted and released freely, and should not be too public.

Three waits: The water begins to dry up in the "Book of Rites" note: "The water is the way to do", the spring and summer air arrives, so it is long, and the autumn and winter air returns, so it dries up.

It is said that the rainfall began to decrease at this time, and due to the dry weather and the rapid evaporation of water vapor, the amount of water in the lakes and rivers became less, and some swamps and puddles dried up.
