Why do swallows always stop at the door?

Swallows do not settle in front of any house, and generally choose a house facing north and south.

One more thing I understand: Swallows like lucky people to settle down at the door?

Three years ago, my neighbor built a new house 20 meters in front of my house. It was beautifully decorated and should be a swallow's nest.

I know that when winter goes and spring comes, swallows don't build nests. In autumn, unpleasant things happen.

Of course, this may be a coincidence. However, Ying moved to the forest, Yanhe moved to a new house, and moved into a new house.
