What do jackals mean when they sacrifice animals and plants turn yellow and fall off? What are these words for?

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. This means that in this solar term, jackals will show their prey before eating it, the leaves on the earth will turn yellow and fall, and the stinger will not eat in the cave and hang his head and go into hibernation.

The first frost is the last solar term in autumn among the 24 solar terms in China, followed by beginning of winter, and beginning of winter means the arrival of winter. During the first frost, jackals began to catch a lot of prey. When they caught more than they could eat, they left them there. From the human point of view, this is like "offering sacrifices to animals"-offering sacrifices to heaven to return books with animals and offering sacrifices to autumn gold.

Write Frost's poem first:

"Nanxiangzi Chongjiu Hanhui Building presented to Xu Junyou" Su Shi in the Northern Song Dynasty;

The first frost water marks, light blue scales exposed to the distant continent.

The strength of the wine is fading, and the wind is soft and sad. Broken hat, deep feeling but pricking head.

If the festival is rewarded, it will ruin the autumn.

In the end, everything is a dream. Have a rest. Huang Die is also worried tomorrow.

Translation:

In the early frost and late autumn, the water level drops, and the sandbar in the middle of the river is exposed in the distance. I didn't know that the breeze was blowing until the strength of the wine dropped, which made people feel chilly. Broken hat is sentimental and reluctant to be blown off by the wind.

How to spend the Double Ninth Festival is just drinking to kill time. Everything in the world is an empty dream for a moment, so don't mention the past again. After the Double Ninth Festival, the color and fragrance of chrysanthemums will be greatly reduced, and even butterflies obsessed with chrysanthemums will sigh and worry.
