Mo Yan is the first Chinese writer to win the Nobel  Prize for Literature, and he is an important figure in the contemporary Chinese literary world. His novels have their unique regional characteristics and created a unique literary style. In his novel "Frog", five epistolary writings were written, with the obstetrician "aunt" as the main line, showing China's rural birth history in the past 60 years, writing about the before and after of family planning, touching the the hidden pain of the Chinese soul. In this thesis, I will study the language expression and artistic characteristics of "Frog", and summarize the language expression characteristics of "Frog" through close reading of the text and analysis of examples, including many short sentences, insertion many words, parallel sentences and metaphorical sentences, etc. The expressive features of these languages also have rich artistic effects in the text, such as irony, self-mockery, humor, etc., and their changes in language and the use of sentences can also reflect Mo Yan's sensitivity to language, and his artistic skills. In addition, from an overall point of view, Mo Yan's "Frog" obviously has the characteristics of simple, natural and localized narrative. Therefore, a detailed study of the language expression characteristics in Mo Yan's novel "Frog" can help us better understand Mo Yan's artistic characteristics, and diversity and possibility with Chinese language.
