The paper aims to research how to use the theory of infinite extension to transform the historical data of Dayu under the framework of the two axis theory, and integrate it into the morphological creativity to put forward the method of extracting and deducing the figures of historical and cultural celebrities.Using the analysis of "wide and narrow" in the two axis theory to extract morphemes, using the Chinese word segmentation system secondary clustering to screen morphemes, a set of graphic codes formed by the derivation is performed three times; through the "exhibition" analysis, the graphic elements under the cultural subordination are obtained; "prick points" are added to the graphic elements, and graphic creative design is carried out under this thinking limit to enhance artistic expression; finally the commercial pattern design is carried out through element reconstruction and visual form creation.By combining the theory of infinite derivation, morpheme clustering and aesthetic evaluation model, a new Dayu graphic creative method based on design semiotics is constructed, which provides a new theoretical basis for the creative design of historical and cultural celebrities' graphics and constructs a new design path.
