Frost is one of the twenty-four festivals, the weather is getting colder, the beginning of frost.

Like the harvest of the new grain on earth, it is used to sacrifice to heaven to show the return, and in this way to pray for good weather in the coming year. It is the righteousness of the beast, and the essence of man.
The second wait for the yellow fall of grass and trees. Autumn is over, the grass is withered, the frost falls butterflies fly. In the fall, the west wind rolls, urging down the leaves, blowing withered grass. The gradually cold climate has destroyed all the vitality of nature once and for all. The green is reduced, the red disappears, the geese have no trace of shadow. And the human emotion, also into the deep trough. The sadness of parting from one another, the miserable wind and rain, all show the sadness of the late fall, touching the heart.
The third wait is for the stinging insects to be salted down. Jellyfish are also all in the hole not moving not food, head down to enter the hibernation state. At this time, nature is a silent beauty. After the vibrant spring, lively summer, harvest celebration of the fall, the cycle of life, and into a dormant state. The bees and butterflies are nowhere to be seen, and the stinging insects are silent, all preparing for the long winter. It was a gesture of cultivation, looking forward to the new life in the coming year.
