There are many swallows under the eaves. What's the point?

Children or bees nest under the eaves, which is a symbol of good luck in geomantic omen. It means that the house is extremely prosperous and the environment is suitable for survival, so as to attract swallows or bees who are very picky about the nesting location to nest. Houses with swallows or bees nesting are usually lucky. It is not recommended to tear down nests unless they have become empty nests and swallows or bees have moved. The older generation also said that an empty nest would destroy the original fortune and damage the original good fortune, but there is no scientific evidence or facts to prove it, so I suggest taking it as a reference. But if there are bees nesting under the eaves, it is easy to consider safety. In principle, as long as it does not affect normal life, it is not recommended to dismantle it. There are many kinds of swallows. Traditionally, the swallows we know in ancient books have a proper name "Domestic Swallow", which is different from other swallows with its snow-white belly and scissors-like tail. The reason why domestic swallows call themselves. Among many swallows, their habitats are most closely related to people's lives. They often nest in the corner of the house. In modern society, few birds are so afraid of people and deliberately approach them. In rural areas, besides sitting on the corner of the building, fluorescent lamps in the hall are also places where they are willing to nest. Swallow has been one of the mascots of China people since ancient times.
