It means the beginning of autumn. By the beginning of autumn, the Wutong tree began to shed its leaves. However, the arrival of autumn means that the daily average temperature has dropped to about 22 ℃. At the autumnal equinox, most parts of China have entered a cool autumn. During the "autumnal equinox" season, the daily average temperature in the Yangtze River Basin and its vast areas to the north of China has dropped below 22 ℃, which is a phenological autumn. At this time, the cold air mass from the north already has a certain power. The rainy season has ended in most parts of the country. Words such as cool wind, blue sky, sunny wind, crisp autumn, fragrant osmanthus and yellow crab fat chrysanthemum describe the scene at this time. After the autumnal equinox, the position of direct sunlight moves to the southern hemisphere. The northern hemisphere gets less and less solar radiation, while the ground loses more heat, and the speed of temperature reduction is significantly accelerated. The agricultural proverb says, "an autumn rain and a cold". "The wild goose gate opens in August, and the wild geese bring frost at their feet". It is not surprising that the temperature in Northeast China drops as early as the year equinox, and the frost is seen at the autumn equinox.

autumnal equinox in 2020? The autumnal equinox originated from the tradition of "Moon Festival" in ancient China. In ancient times, there was a saying of "offering sacrifices to the sun in spring and the moon in autumn". Now the Mid Autumn Festival comes from the traditional "Moon Festival". According to textual research, the original "Moon Festival" was set on the "autumn equinox", but because this day is different every year in August of the lunar calendar, there may not be a full moon. Sacrificing the moon without the moon is a great evil. Therefore, the "Moon Festival" was later adjusted from the "autumnal equinox" to the Mid Autumn Festival. According to the interpretation of the seventy-two seasons of the lunar calendar, in the middle of February, the minute is half, which is half of the ninety days, so it is called the minute. Autumn is synonymous. "Dong Zhongshu of the Han Dynasty:" as for the month of the Mid Autumn Festival, the sun is in the East and the Yin is in the west, which is called the autumn equinox. The autumn equinox is half of yin and Yang, so it is cold and hot day and night. According to the lunar calendar, "beginning of autumn" is the beginning of autumn and "frost fall" It ends in autumn, and the "autumnal equinox" is exactly half of the 90 days from the beginning of autumn to frost. September 23 or 24 of the Gregorian calendar is the autumnal equinox of the twenty-four solar terms.,
