The characteristic of preschool education lies in the playfulness of educational content, which is based on cultivating children's interest, consciousness and ability, rather than knowledge education. Only by accurately reflecting the content in a form suitable for children's physiological and psychological characteristics can the above objectives be achieved. In the design process, this book pays attention to the following characteristics:

◎ Take the lives of the two protagonists as the background, and take some stories that happened in their lives as clues to show all aspects of children's lives. It is easy for children to understand and accept, and children will feel that these things happen around them.

◎ Pay attention to operability and proceed from children's interests. In design, this book embodies the forms that children like to see and hear, such as linking, drawing, sketching and cutting, and pays attention to achieving educational goals through children's own hands-on, observation and experience.

Pay attention to the effective integration with other fields of children's education. Children's safety education is a part of children's life education, which is an important content in the social field. Life education involves all aspects of children's lives, so this book focuses on starting from life, putting forward the content of safety education from life education, and effectively integrating other educational contents into safety education, thus building a complete knowledge system for children.

◎ An evaluation page is arranged at the end of each book to provide parents or teachers with the knowledge of the book and evaluate their children's learning.
