During the Ming and Qing Dynasties, memorial biographies written by scholars for their own concubines emerged in multitude, reflecting the compassion and a certain degree of respect of the scholars for the humble and weak, showing the shining glory of humanity in the scholars. However, from the analysis of the text, especially in comparison with the memorial biographies written for their wives, the disparity was obvious in the social pyramid between the male scholars and their concubines, confirming that gender and class inequality in particular were insurmountable gaps in the establishment of emotional relations. In addition, the narrative of "pampered concubines and ill-treated wives (宠妾虐妻)," which was not uncommon in fictional literature, was difficult to trace in the memorial biographies written by the scholars. It was also a vivid example of the contrast between the scholar culture and social reality and folk culture. Why and how to speak, what cannot be said, and the style, the social ideological trend and the individual thoughts behind such text are the first-hand materials to analyze the mentality of scholars and its influence on the evolution of the writing style of biographies.
