What are the customs of the autumnal equinox solar terms?

According to custom, farmers have a holiday on the autumn equinox. Every family should eat dumplings. Ten, twenty or thirty dumplings that don't need to be wrapped are cooked, and a thin bamboo fork is placed on the outdoor ridge beside the field, which is called sticking the sparrow's mouth without destroying crops.

The autumnal equinox is the sixteenth of the twenty-four solar terms, and the time is generally from September 22nd to 24th of the Gregorian calendar every year.

On the day of the autumnal equinox, the sun reaches the longitude 180 (autumnal equinox), almost reaching the equator of the earth, and the length of day and night is equal all over the world (regardless of the refraction of the sun light by the atmosphere and the shadow in the morning). In ancient times, there was a saying that "the sun is sacrificed in spring and the moon is sacrificed in autumn". The autumnal equinox used to be the traditional Mid-Autumn Festival, but now the Mid-Autumn Festival is derived from the traditional Mid-Autumn Festival. With the approval of the CPC Central Committee and the State Council, since 20 18, the annual autumnal equinox has been established as "China Farmers Harvest Festival".
