1. Children can have a sense of rules through picture books. For example, "David, No" uses picture books to teach children not to do dangerous actions, not to play baseball at home, and not to eat too much. This kind of story is much more useful than adult preaching, because children have idol complex.
Children can learn about social relations through picture books. For example, in The Rooster's New Neighbor, the rooster has a new neighbor owl, and their habits are different. How did the last two good friends figure out how to communicate?
3. Children can be taught to know themselves through picture books. For example, "I like myself" enhances self-confidence while recognizing myself.

Children can easily understand mathematics, nature and science through picture books.
