The autumnal equinox has two meanings, one is equal share, and the other is equal share of day and night.

The autumnal equinox solar term is not only an important agricultural solar term in an autumn newspaper country, but also develops the connotation of celestial worship with the theme of loving life, and also shows the efforts of ancient people in China to build social order according to the seasons. In the connotation of these solar terms, we fully understand the ancient people of China's respect for nature and love for life.

The autumnal equinox is one of the four solar terms as important as the vernal equinox, summer solstice and winter solstice. It is 16 of the 24 solar terms and the fourth solar term in autumn. The word "autumnal equinox" has two meanings. First, it is equally divided, that is to say, by the autumnal equinox, autumn is over half; Two fingers divide day and night equally. At this time, the sun runs on the ecliptic and reaches longitude 180. The sun shines almost directly on the equator, and most parts of the earth are equal day and night.

The autumnal equinox is a solar term with complex connotation, involving farming, astronomy, personnel and many other aspects, which embodies the attitude and emotion of China people who respect nature and love life.

First of all, the minute is a very important agricultural solar term, and it is the "Sanqiu" busy season of autumn harvest, autumn planting and autumn ploughing. On the one hand, "Everything is born at the vernal equinox and made at the autumnal equinox" (Wen Zi Ren Shang), and the autumnal equinox is the harvest season for most crops. For example, in the northeast, rice, corn, sorghum, soybeans and sweet potatoes are all harvested in the autumn equinox, while the autumn harvest in North China is almost over; On the other hand, the autumnal equinox is also the sowing time of crops such as winter wheat. There is a saying in North China that "the white dew is early, the cold dew is late, and the autumn equinox is the time to plant wheat".

The autumnal equinox is also the key moment to determine the high yield of double-cropping late rice in southern China, and it is necessary to strengthen field management. So there is an agricultural proverb that summer is busy for half a month and autumn is busy for forty days.
