If the swallow does not enter the "Bitter Cold Gate", how does the swallow distinguish between the "poor" and the "rich"?

When it comes to swallows, I believe everyone is familiar with them. Swallows are also called clumsy swallows. They are extremely small, have pointed and narrow wings, not too many feathers, and have single-color feathers. They are one of the most flexible passerines. In the past, poor people could only live in thatched houses. Of course, swallows would not choose to build their nests here. Moreover, swallows do not like to live in noisy places. They will choose to build their nests in a harmonious family. This will Even quieter, I have to say that swallows are still very smart, so as the saying goes, swallows do not enter the "door of bitter cold".

If swallows do not enter the door of bitterness, there is another saying in rural areas: "Swallows do not enter the door of sorrow." Although swallows are birds that like to be close to humans, they also have their own habits. Birds that like a quiet atmosphere, while people who are worried about home will often make noisy noises, and the chickens and dogs jumping all over the yard are unbearable, not to mention the swallows that like a quiet atmosphere. Since ancient times, there is a saying that everything is prosperous at home, and family Only when there is harmony can the family business prosper. If your relatives are not united, then there is no need to talk about the family business.

If this family quarrels all day long, they will choose to leave and start over somewhere else, because they are afraid that their nest will be stabbed and they will end up homeless. . In the animal kingdom, the tiger is the king of beasts, the phoenix is ??the leader of the year, and the swallow is just insignificant. All birds are afraid of people. They will build their nests in remote mountainous areas to avoid being destroyed by people. Only swallows dare to put their own nests The only advantage of building the nest on the eaves of other people is that it can cultivate feelings with people and avoid people's harassment.

Although there are fewer and fewer swallows now, when spring comes, the swallows will still keep calling to tell people that spring is coming. Nowadays, there are many unscrupulous traders in society illegally catching swallows. I hope everyone can protect the ecological balance of nature and not kill or harm them.
