With the increasing global demand for Chinese language, the teaching of Chinese for Specific Purposes (CSP) has occupied an increasingly important position in the teaching of Chinese as a foreign language. However, traditional teaching methods often neglect the role of non-verbal symbols in language comprehension and communication. The multimodal discourse theory provides a new perspective for CSP teaching, which can effectively enhance students’ understanding and mastery of specialized terminology and language application skills by integrating multisensory symbol systems such as language, vision, hearing, and touch. This paper starts from the current situation of teaching CSP and analyzes the adaptability between multimodal discourse and CSP teaching, aiming to provide theoretical support and practical suggestions for the innovation of the teaching mode of CSP.
