2. Since ancient times, there has been a legend in China that auspicious places attract phoenix. If lucky birds such as magpies and thrushes nest in front of the door, it is the best sign. But if it is a symbol of unlucky animals such as crows, don't panic. Not nesting in the house will not destroy the feng shui at home. A bird calls its nest in a tree, its nest in a hole and its painting in a tree. Bird's nest belongs to wood, fire in the south and water in the north. According to the law of five elements, aquatic wood and wood are the most prosperous houses, with doors facing south and north, which can bring vitality and good luck to families.
