What does Frost Fall mean?

The meaning of frost

1. Frost Descent occurs around October 23rd of the Gregorian calendar every year when the sun reaches 210 degrees of the ecliptic longitude. "Frost" is formed when water vapor on the ground condenses when encountering cold weather. "Shuangjiang" does not mean frost, but it means that the weather is cold and the first frost will appear on the earth.
2. With the arrival of Frost, crops and grass begin to turn yellow and shed their leaves, entering the late autumn, late fall and late autumn when "thousands of trees turn yellow". Therefore, "Shuangjiang" is a solar term representing the change of temperature, which means that the weather turns cold, dew condenses into frost, and frost begins to appear. In addition, "Shuangjiang" is also the solar term for the transition from autumn to winter.
