Abstract：A lot of studies about Chinese synesthesia have been made in Chinese academic community since Mr. Qian Zhong shu started the exploration of this rhetorical phenomenon. Based on the present investigations, this paper discusses the limits of Chinese synesthesia. It holds that synesthesia is just limited to the interaction of senses. The words for sense impressions cannot only be used in their original meanings, but also in their derivative meanings. This paper makes a thorough analysis of linguistic materials and classifies Chinese synesthesia into four kinds in terms of their psychological mechanism.
