What is the alias of the autumnal equinox? Autumnal equinox

The autumnal equinox used to be the traditional "Festival of Sacrificing the Moon". For example, in ancient times, there was a saying that "the sun is sacrificed in spring and the moon is sacrificed in autumn". Now Mid-Autumn Festival comes from the traditional Mid-Autumn Festival. According to textual research, the first "Moon Festival" is set on the day of "Autumn Equinox", but there may not always be a full moon because of the different dates of August in the lunar calendar every year. And the moon without the moon is a big spoil the fun. Therefore, the Mid-Autumn Festival was later transferred from the Equinox to the Mid-Autumn Festival.

The autumnal equinox, like the vernal equinox, is the earliest solar term established by the ancients. According to "Spring and Autumn Stories Yin and Yang Incoming", "The autumnal equinox is accompanied by Yin and Yang, so it is cold and hot day and night."

"Equinox" has two meanings:

First, according to China's ancient beginning of spring, Changxia, beginning of autumn and beginning of winter, the four seasons are divided. The autumnal equinox lives in autumn for 90 days and divides the autumn equally.

2. At this time, 24 hours a day are divided equally, each 12 hours. This day is the same as the "spring equinox" day. On the day of the "autumnal equinox", the sun is almost directly at the equator. After that, the position of direct sunlight moved south, and the days in the northern hemisphere became shorter and the nights became longer.

In ancient China, the autumnal equinox was divided into three periods: "When thunder comes, the sound will stop;" Second, wait for scorpion blank households; Wait for the water to dry. "The ancients thought it thundered because the sun be the spirit is strong, and the yin began to fill after the autumnal equinox, so it didn't thunder. The word "blank" in the second phase means fine soil, that is to say, due to the cold weather, secluded small insects began to hide in Tibetan caves and sealed the hole with fine soil to prevent cold air from invading. " The water began to dry up "means that the rainfall began to decrease at this time. Because of the dry weather, the water vapor evaporates quickly, the water in lakes and rivers becomes less, and some swamps and puddles dry up.

In the autumn equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, which causes repeated precipitation and the temperature drops again and again. As people often say, it's time for "an autumn rain and a cold", but the daily precipitation after the autumnal equinox will not be great. At this time, the field farming in the south and the north is different. In northern China, there is an agricultural proverb that says: "The white dew is early, the cold dew is late, and it is the right time to plant wheat in the autumn equinox." Proverbs clearly stipulate the sowing time of winter wheat in this area; And "White clouds come in autumn equinox, good songs and good rice seeds are everywhere" reflects the planting time of rice in Jiangnan area. In addition, the working people's taboos on the autumnal equinox solar terms are also summarized as proverbs, such as "The autumnal equinox is only afraid of lightning, how much is it?"
