Abstract：Evil Mother-in-law has been an important motif since it was represented in many Chinese ancient poems and novels. Based on the gender theory, it was obvious for the narrative about the motif to represent the gender relations between the mother-in-law ang daughter-in-law, because the patriarchy was made from the relations. However, it was different from the rule of the western feminism, although the maternal right was the replacer of the patriarch in China, it was still limited. As a result, the representation of the motif is to construct the Render relations between a virtuous mother-in-law＇ and a filial daughter-in-law.
