Lu Xun's name is Kong Yiji.

Described by Lu Xun as "drinking standing in a long gown", Kong Yiji was a lower-class scholar who was devastated by the imperial examination system in feudal society at Xianheng Hotel in Luzhen. For such a corrupt scholar who was harmed by ethics and power, the author named him after compressing the semi-unreasonable words of Kong Yiji, an adult on red paper, which included Lu Xun's contempt and ridicule of Confucius and Mencius.
