The origin of the first frost in the twenty-four solar terms

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 and hang their heads into hibernation.
