Swallow: Why does the old saying say that swallows come to make a fortune? Why didn't the teacher do it for several years? What happened?
Whose house the swallow goes to settle down does not mean that this family is really rich or expensive, and it will definitely be rich and powerful. We must understand that in the past, the first reason why swallows chose to settle in a big family was that this family developed first, set up a huge family business and built a magnificent courtyard, so they recruited swallows.
