In a vibrant spring, Little Bear and Father Bear want to build a beautiful house. So they came to a dense forest to cut down trees.

A forest with dense green leaves. The bear said, "Dad, the trees here are not strong yet. Come and cut it in summer. " Father Bear said, "Well, let's cut it in summer."

Soon came the hot summer, the trees grew greener and taller, and the trees were full of beautiful flowers. Little bear quickly said to his father, "Dad, we can't cut down trees now." Xiaohua will die. Come back in autumn. " Dad thought about it and said, "Well, let's cut it in autumn."

In autumn, the leaves turn yellow and fall like dew, and the branches are covered with fruits. The bear said, "Dad, we can't cut down the tree, or the fruit will be broken." Dad said, "Well, let's cut it in winter."

Another season has passed, and in winter, heavy snow flies down like a bird. On the branch, a bird nestled in its mother's arms, and several birds were playing games. The bear said, "Dad, let's give up cutting down trees. If we cut down trees, birds will have no home. " Father bear looked at the bear, then at the lovely bird and said, "Well, we have to give up cutting down trees."

Small animals come to praise the bear family, care for trees and protect the birds' homes.
