What does the story of the farmer and the dog tell us?

Farmer and Dog tells us that even if it won't hurt you at present, you should always pay attention to it and make preparations as early as possible to avoid being hurt. Don't gloat when you see others get hurt, but be careful yourself. If you're just glad you're not unlucky, it's not far off. Therefore, people should have the awareness of nip in the bud.

Introduction to the story:

The weather is very bad, the cold wind is howling and there is heavy snow all over the sky. It has been raining for several days. The outside of the house is white and the snow on the ground is at least three feet thick. Farmers really don't want to go out to find food in such bad weather. But there is not enough food at home, and it is almost finished. What should we do?

The farmer looked at the heavy snow flying outside the house through the crack of the door, sighed, picked up a butcher knife and killed the sheep at home. The farmer ate mutton for two days in a row, but the snow didn't stop. The farmer sighed, picked up a butcher knife and killed the goat.

The goat finished eating, but the snow still didn't stop. The farmer sighed again, picked up the butcher's knife and killed the cow. While the beef was cooking in the pot, several dogs in the farm quietly got together.
