First frost solar terms introduction:

1. The first frost is generally the first frost in the twenty-four solar terms when the sun reaches 2 10 degrees on October 23rd in Gregorian calendar. The first frost is the last solar term in autumn, which is the transition from autumn to winter. There is a lot of heat dissipation on the ground in autumn, and the temperature suddenly drops below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure.

2. Twenty-four solar terms say the first frost: in mid-September, the air is quiet and condensed, and the dew is frost. "First frost" means that the weather is getting colder and the dew condenses into frost.

3. In ancient China, the first frost was divided into three stages: first, the jackal sacrificed animals; Second, the vegetation is yellow; Three stings are salty. The jackal began to catch prey, sacrifice animals, and sacrifice to heaven to repay the kindness of animals, paving the way for sacrificing autumn gold; The leaves on the earth turned yellow and fell; The stinging insects are motionless in the cave and hang their heads into hibernation.
