Abstract：Based on the stance triangle theory, this paper compares the usages of“shuo shihua” ( to tell the truth) and “shuo zhende” ( no kidding) through data analysis. Both of them are very flexible in syntactic position, but “shuo shihua”can appear in questions, sometimes followed by modal particle, and tend to connect negative subjective facts. These features reflect that the interaction between subject1 and object, expressing the truth of the information, and also the interaction between two subjects, reducing the negative effect when it expresses the truth. The main function of “shuo zhende”is to emphasize the degree of assurance to the truth and to remind hearers, expressing the interaction between two subjects.
