What is the legend of the ancient first frost?

The first frost is the eighteenth of the twenty-four solar terms, which means that the weather is getting cold and first frost begins. At the end of September each year (1October 23rd or 24th 10), the first frost is regarded as the last solar term in autumn when the sun reaches 2 10.

"Twenty-four solar terms" said: "In mid-September, the gas is cold and condensed, and the dew is like frost." At this time, when the temperature drops below 0 degrees, the water vapor in the air condenses into white crystals on the ground, which is called frost. The first frost refers to the first frost. Plants that are not hardy will stop growing and present a scene of late autumn, which is a good time to enjoy maple leaves.

The word "jackals are sacrificial animals" first appeared in Yizhoushu: "On the day of the first frost, jackals are sacrificial animals". He also said, "It is not good for jackals not to sacrifice animals." It means that in this solar term, the jackal began to catch prey, sacrificed the beast with the first thing he caught, and returned the book to heaven with the beast, which paved the way for offering autumn gold. Like the harvest of the new valley on the earth, it is used to worship the sky to show the return and pray for good weather in the coming year. It is the meaning of animals and the foundation of human beings.
