Carve a big bird to feed a small bird.

Does the subject want to ask, "What is the meaning of carving big birds to feed small birds?" It means that parents raise their children. The big bird feeds the small bird, that is, the big bird spits out the food in its mouth and feeds it to the small bird. This is the spirit that parents are not willing to give their children food and clothing, but are willing to suffer for their children's happiness.
