Abstract：Abstract: To investigate the impact of the semiotic meanings of texts, images on the meaning construction of multimodal product warnings, this paper conducts a case study on two types of warnings on cigarette packages from the perspective of . It analyzes how they differ in style when reporting the official voice “smoking harms your health” and then discusses their dialogical orientations thereof. It is found that with the interaction and coherence achieved between different semiotic systems, speakers of the new type express more dialogical orientations than those of the traditional type, but the multiplicity of warnings in expression has failed to cover their implicit enclosedness in meaning. For better persuasive effects, this study suggests that multimodal product warnings be constructed in the embedment of an opener and more heteroglossic context.
