Why do you say that the autumn equinox does not raise fields?

This is because the autumnal equinox is the harvest season. After the autumnal equinox, the temperature will gradually drop, and it is not suitable for crop growth after the weather turns cold. Therefore, you can't farm after the autumnal equinox, and it won't last long after planting.

Autumnal equinox is an important solar term in agricultural production. After the autumnal equinox, the growing period of field crops in the northeast plain ended and crops began to be harvested. As the agricultural proverb goes, the autumn dew is divided into nights, and it is cold all night.

In the year when the temperature in Northeast China drops early, the autumnal equinox begins to frost. In order to protect immature crops from frost and reduce production, when the cold wave strikes, people organize themselves, and each household carries firewood to the field for vigil in sections. First frost is just around the corner, and they light it together, only to see dozens or even hundreds of miles of Fiona Fang soaring into the sky to drive away the cold wave. The scene is spectacular.
