"Compendium of Materia Medica and Poultry Department" contains: "Ciwu: This bird is born, and its mother will eat for 60 days, and if it is long, it will eat for 60 days." When the little crow grows up, the old crow can't fly to find food by himself. Little crows will look for food to feed their mothers in turn. The story of crow feeding back has been passed down from generation to generation, and many people know it. To some extent, the "feedback complex" lingering in people's minds is still an important force to maintain the harmony, warmth and tranquility of society and families.

In legend, the story of crow feeding back is the most touching one. Crow, a bird with a black and ugly face, is generally disliked by human beings because people think it is unlucky. It is this annoying bird that can't enter the elegant hall and ink painting, but it has a virtue that is truly worthy of our universal praise-caring for the elderly, and it is a model among animals in caring for and respecting the elderly. It is said that this bird grew up under the care of its mother. When her mother was old and weak, unable to eat or blind and unable to fly, her children would look around for delicious food, bring it back to their mouths, and feed it mouth to mouth until the old crow died and couldn't eat any more. This is what people often say "the crow feeds back".
