1, jackals are sacrificial animals.
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.
2. The vegetation will turn yellow in the second season.
Paraquat is exhausted in autumn, and butterflies fly in first frost. In autumn, the west wind is rolling, knocking down leaves and blowing drafts. The gradually cooling climate has destroyed all the vitality of nature again and again. Green decreases, red disappears, and geese disappear. And people's emotions have also entered a deep trough. Don't hate to stay sad, wind and rain are bitter in late autumn, touching people's hearts.
3. Three stings are salty and easy to occur
The stinging insects are motionless in the cave and hang their heads into hibernation. Nature at this time is a silent beauty. After a vigorous spring, a lively summer, a festive autumn and the cycle of life, it entered a dormant state. There are no traces of bees and butterflies, and the stinging insects are silent, all preparing for the long winter. It is a gesture of practice, looking forward to the new students in the coming year.
Precautions for first frost
1, anti-autumn dryness
One of the most important climatic characteristics in autumn is that it is very dry, and the autumn dryness is very obvious during the first frost. So you can prevent some humidifiers at home from moisturizing, or drink more water at ordinary times.
2. Prevent autumn depression
In late autumn, the weather is getting colder, the flowers and trees are yellow, and everything is bleak, which is easy to cause anxiety and make people depressed. Therefore, there is a saying of "sad autumn", and outdoor sports can be increased at ordinary times.
3, anti-autumn cold
Traditionally, there is a saying that "the cold dew is not cold, and the first frost weather changes". Because the first frost is the beginning of the transition from autumn to winter, the temperature difference between day and night will increase at this time, and it is more necessary to pay attention to adding clothes to prevent cold.
