The Wondrous Kingdom of Number is a representative work among Li Yupei’s scientific fairy tales themed around mathematics. Highlighting the theme of numbers，the work systematically popularizes mathematical knowledge，including integers，fractions，decimals，and algebra. It simultaneously promotes scientific thought centered around dialectical development and fully constructs a mathematical fairy-tale universe as a “secondary world.” Emphasizing interactive narrative techniques between the fairy-tale and real worlds，the book employs personification and concretization to enhance the vividness of the “Kingdom of Number，” creating an immersive and tangible fairy-tale experience. In terms of creative techniques，it adheres to the principle of child-centeredness by stressing a simple plot structure，narrative conflicts，and engaging storytelling. By using accessible scientific fairy tales to dissolve the rigidity of knowledge，the dissemination effect of mathematical concepts and scientific thought is optimized.
