What do you know from this story?

This is a fairy tale full of childlike innocence. The text mainly tells that Cotton Girl is ill. She asked swallows, woodpeckers and frogs to be kind to themselves, but they could do nothing. When aphids proudly ate the juice of cotton girl, ladybugs swept them away. The cotton girl lived happily again, spitting out snow-white cotton. The text tells us the scientific common sense of the pests where swallows, woodpeckers, frogs and ladybugs eat respectively through the story of cotton girl asking animal doctors such as swallows and woodpeckers to treat herself, and integrates biological common sense into vivid stories.
