Talk about the significance of the following paper-cuts.

The first picture tells us that when children are young, they always depend on their loved ones. (or tolerant people always don't care about anything)

The second picture tells us that when children grow up, they can face things themselves. (or people need to live in harmony, although sometimes it may affect their own interests: grass)

The third picture tells us that when the child is fully mature, he will leave his relatives without worries. Although relatives want to be with their children forever, as long as the children live and develop well, they will still watch them leave their sight.
