Customs during the Autumnal Equinox
1. Sending Autumn Cows
When the Autumnal Equinox arrives, people go from house to house sending pictures of Autumn Cows . Sending Autumn Ox is actually to print the lunar solar terms of the whole year on two sheets of red or yellow paper, and also print the picture of farmers plowing the fields, which is called "Autumn Ox Picture". The people who sent the pictures were all folk singers who were good at talking. They mainly said something about autumn plowing being auspicious and not contrary to the farming season. Every time they visited a house, they immediately fell in love with the scene and said whatever they saw until the owner was happy and gave money.

On the day of the autumnal equinox every year, tens of millions of people around the world do the "egg-standing" experiment.

The meaning of the autumnal equinox
The ancient Chinese book "Spring and Autumn Dew: The Entry and Exit of Yin and Yang Part 2" says: "The autumnal equinox is Yin and Yang. The phase is half, so the day and night are even and the cold and heat are equal. "The "fen" of the autumnal equinox means "half". The meaning of "Autumn Equinox" is based on the season division method in ancient my country with the beginning of spring, beginning of summer, beginning of autumn and beginning of winter as the beginning of the four seasons. The autumnal equinox days occupy the 90 days of autumn and divide the autumn equally.
The meaning of the Autumn Equinox "The Collection of Seventy-Two Hours of the Moon Order": "In mid-August...the explanation is the Spring Equinox." "fen" means the equinox of day and night, which is the same as the spring equinox. On this day, the sun shines directly on the earth's equator, and day and night are equal. Since then, the position of direct sunlight has moved further south, the days have become shorter and the nights have become longer in the northern hemisphere, and the temperature has dropped, which has universal significance across the country.
After the autumnal equinox, the days get shorter and the nights get longer in the northern hemisphere, while the days get longer and the nights get shorter in the southern hemisphere.
The days are getting longer and longer from the winter solstice, but from the vernal equinox, the days are longer than the nights. From the summer solstice, the days are getting shorter and shorter, but from the autumnal equinox, the days are shorter than the nights.
"Autumn Equinox" is also the "Harvest Festival of Chinese Farmers".
The autumnal equinox is the sixteenth solar term in the "Twenty-Four Solar Terms" of the Chinese lunar calendar, which happens to be half of the 90 days from "Beginning of Autumn" to "Frost Descent". During the autumnal equinox, the wind is gentle and the sun is bright, the osmanthus is fragrant, and the crabs are fat and chrysanthemums are yellow. It is a harvest scene with melons and fruits fragrant and the barns full. Traditionally, the autumnal equinox is not only the end of autumn harvest and winter storage, but also the starting point of spring plowing and summer planting. As a farmer's proverb in North my country says: "White dew comes early and cold dew comes late, so the autumnal equinox is the right time to plant wheat." Therefore, the country marks the annual equinox as the beginning of spring plowing and summer planting. The establishment of the Autumnal Equinox as the "Chinese Farmers' Harvest Festival" not only pays tribute to and inherits the traditional "twenty-four solar terms", the crystallization of ancient wisdom, but also reflects that contemporary Chinese people understand the natural replacement, comply with the laws of nature, and adapt to sustainable ecological development.
