Why did Mr. Lu Xun lose interest when he commented on Yingying Biography in A Brief History of Chinese Novels?

Biography of Yingying has successfully shaped the classic image of Cui Yingying. She is a girl from a gentry family, and her heart is full of contradictions between love and courtesy. The novel profoundly reveals the ideological contradictions and personality characteristics brought about by her birth and growth, and describes in detail the process of inner conflict when the girl resists traditional ethics. Yingying's tragic character is both simple and rich. She finally refused Zhang Sheng's request, reflecting the change of her character from weak to strong. Yingying's tragic character is both unique and universal, which typically summarizes the same fate of countless women who were bound by feudal ethics and abandoned by unfaithful men in history. In the figure gallery in the history of China literature, Cui Yingying, Du Liniang and Lin Daiyu are all women who pursue free love and dare to challenge feudal ethics. They are all brilliant female images with different historical stages and connotations, and Cui Yingying is the best in the gallery. In contrast, Zhang Sheng's image is inferior. Especially at the end of the article, in order to excuse Zhang Sheng's shameless behavior of abandoning Cui Yingying, the author called Cui Yingying "stunner", "Uber" and "if you don't demon him, you will demon others", which not only made the characters inconsistent, but also caused contradictions in the theme. As Lu Xun's "A Brief History of Chinese Novels" said: "It is boring to pretend mistakes at the end of the article."
