During the Song Dynasty, Bai raised birds.
Birds are unfamiliar and fearful of people, so it takes enough patience to tame them.
Once tamed, it will never leave you.
But freedom is the nature of a bird. In order to keep the bird, it is necessary to clip its feathers at this time.
Clip your wings and never see the sky again.
If the bird still wants to escape, it means that the bird cannot be kept and its heart is too wild.
Then make it into a specimen and keep it for a lifetime.
Later Song Shibai discovered that he had become a bird.
