The entire book is laid out in short Chinese-English phrases, using age-appropriate Chinese language and simple, practical English sentences to create an immersive, bilingual atmosphere. In the main text, long Chinese sentences are used to transition and connect the storyline, while English phrases with fewer words are used for character dialogues. Overall, the book is suitable for beginners. The “Theme Paradise” section of the book sets up an English Situation Theatre around “birthday, travel, hobbies, transportation”, etc., where young readers can practice daily phrases in character to help children's oral expression.
