The origin of the first frost

"Twenty-four solar terms" said that the first frost: in mid-September, the gas was cold and condensed, and the dew became frost. At this time, frost has appeared in the Yellow River Basin of China, and a piece of silver ice crystals is shining in the fields thousands of miles away. At this time, the leaves turned yellow and fell. The ancient book "Twenty-four solar terms" said: "Qi stagnates at the beginning of frost, and Yin begins to coagulate". It can be seen that the "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, hanging their heads and going into hibernation.
