Is it a good thing or a bad thing that pigeons come to my house and stay?

This situation should have been a good thing in the past. Old people often say that having some birds at home means a good family style and a harmonious family. Just as the swallow likes to nest in whose home, this family is also a very warm, happy and harmonious family, otherwise the swallow will not come. So it's really a good thing that pigeons fly to your house. You can build a nest for the pigeon, maybe it will become a member of your family in the future. Then this happy thing will accompany your family and be happy forever. Then no matter what family members do in the future, they will also take advantage of the good luck brought by pigeons. But this phenomenon is not something that ordinary economists can encounter, and it is really fate.
