Through the theory of the Six Categories of Chinese Characters, the work aims to explore the effective artistic expression techniques and the construction of cultural field of Chinese characters in cultural and creative products, and provide a new perspective and idea for the design and research of Chinese character cultural creation. Based on the method of literature review and case analysis, the specific application of "shape, pronunciation and meaning" of Chinese characters in cultural and creative design was analyzed, and its advantages and characteristics were summarized according to thoughts of creating characters in the Six Categories of Chinese Characters. The strategies and innovative approaches of integrating the philology theory into the design of Chinese character cultural and creative products were obtained. The theory of philology is of great significance to the cultural and creative design of Chinese characters. The methods of creating Chinese characters, such as "pictographic", "indicative", "knowing" and "pictophonetic", can stimulate design thinking and deepen the visual logic and semantic expression of Chinese characters in "shape, pronunciation and meaning" in cultural and creative products, which can effectively enrich the expressive force of the external form and the appeal of the core content of cultural and creative products, and provide more theoretical support and creative power for the innovation of cultural and creative product design.
