The work aims to analyze the narrative expression of postmodern characteristics in picture books recreated from traditional stories and. With three picture books recreated from the monster Nian as examples, the expression of postmodern characteristics was analyzed from three aspects:text, image text and iconotext. The current postmodern characteristics such as "collapse of tradition and habit", "intertextuality'", "interesting font design and typography", and "blurring of the boundaries between reality and fantasy" were diversified through iconotexts. The characteristics of "meta-narrative", "gameplay", "non-single linear narrative", and "decentralization" also emerged in text or image text, which brought vigor and vitality to the development of traditional story picture books. However, the characteristics of "breakthrough of space boundaries", "parody", "mashup of media materials", and "unconventional paratext" were not shown, leaving a space for continuous excavation and development in the field of traditional story re-creation. From this, it can be concluded that the postmodern characteristics that are currently well displayed in picture books at present should be used in a more diversified and developmental way. Those postmodern expression techniques that are in the exploration stage and have not yet been shown should be actively tested and boldly used. Iconotext is an excellent way to express postmodern characteristics, and it is worthy of study and utilization by picture book writers.
