1. If a sparrow makes a nest in a certain house, it shows that the feng shui of this house is good. Animals may not be as intelligent as humans, but their ability to choose where to live is still sufficient. They can feel certain magnetic fields or radio waves that humans cannot feel, and can tell where is the most suitable place to live. If birds build nests in a certain house, it means that the geographical location and magnetic field of this house are very popular with birds and will bring them shelter. In turn, the bird's settlement will also bring good luck to the family, helping the family to prosper and have good fortune.
2. Birds have keen perception and they like warm places. The place where they build their nests is warm. If they make a nest in a tree, then it must be facing the sun. If they make a nest in a certain family, then the location must also be facing the sun, and the family's home is very humane and has a warm atmosphere. Lively atmosphere and warm luck.
