Abstract: Background: Jin Yong, a prominent Chinese author, is often associated with the culture of "tea" in China. His martial arts novels are rich in tea culture, including tea ware, tea leaves, tea ceremonies, and tea etiquette, which are all significant Chinese cultural symbols closely related to traditional Chinese cultural concepts and Jin Yong's spiritual connotations. Methods: This paper employs semiotic theory to decode the tea culture symbols in Tian Long Ba Bu(Demi Gods and Semi Devils). Results: Demonstrating how these symbols not only create a Jianghu (lawless world) that combines killing and etiquette but also construct emotional concepts of various ethnic groups. Furthermore, these symbols convey Jin Yong's cultural spirit of "tea and the Dao, tea and emotions, tea and people." Conclusions: As the novel has been internationally recognized, these tea cultural symbols have become an iconic representation of the world's perception of China.
