Is there a bird's nest on the beam at home?

There is a bird's nest on the beams at home. According to our traditional culture and education since childhood, we subconsciously think that swallows will bring good luck to our families, so it is good to have bird's nest on the beams.

This is inseparable from the traditional farming culture in China, because swallows eat insects instead of wheat, so they have been suggesting for generations that they are beneficial birds, without being superstitious, but they should have a caring heart for small animals.

Swallows are beneficial birds, which have many benefits to human beings. Swallows can catch locusts in the fields, protect crops and make crops harvest every year. Swallows can not be separated from human protection, and human beings can not be separated from the help of swallows. Swallows are good for human beings and need protection.
