Internet celebrities have became a popular phenomenon in recent years. Comics on the social media are easy to read and share, therefore, the comic artists see the benefits of it and they have been using it to publish their comics. Base on the perspective of Chinese rhetoric, this study conducts cross-text analysis and case verification through the researcher's comic works on Facebook. Twenty different types of comic rhetorical techniques are found, they are ＂antithesis＂, ＂relative＂, ＂metaphor＂, ＂symbolization＂, ＂metonym＂, ＂hyperbole＂, ＂Irony＂, ＂vague＂, ＂question＂, ＂ambiguity＂, ＂imaginary＂, ＂reversal＂, ＂imitation＂, ＂citation＂, ＂ellipsis＂, ＂progressively＂, ＂parallelism＂, ＂repetition＂, ＂composition＂, and ＂text＂. These techniques can also be classified into nine categories according to the usage. The study discovered that the comic rhetoric and the language rhetoric have a significant similarity in many ways; however, due to the different natures of language and comic, the variation, loss, and innovation may occur during the intermedium conversion. Furthermore, when studying or applying the comic rhetoric, the intention of the comic artists, the intertextual function of the text, the length and the publication method of the comics must be considered as well.
