What is the origin of the first frost?
The origin of solar terms:
Every year around Gregorian calendar 10 year 10, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. 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.
"Twenty-four solar terms" said that the first frost: in mid-September, the gas was cold and condensed, and the dew became frost. "First frost" means that the weather is getting colder and the dew condenses into frost. 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 return books to heaven with 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.
