Li Siguang is a good friend of Lu Xun's sworn enemy Yang Yinyu. Yang Yinyu was the aunt of Mr. Jiang Yang, the wife of Qian Zhongshu, who was then the president of Beijing Women's Normal University.

After the "March 18th Massacre", Lu Xun wrote an article in memory of Liu Hezhen Jun, in which the phrase "If you don't break out in silence, you will perish in silence" was later widely circulated. This article is aimed at Yang Yinyu, but Li Siguang writes for Yang Yinyu, which is of course not allowed by Lu Xun.

Li Siguang knew that he was no match for Lu Xun and didn't write an article to fight back. A quarrel between two people is a quarrel, and a quarrel between one person is a curse. Li See Siguang was silent, and Lu Xun quit playing drums.

Li Siguang didn't work in Shi Jing Library for a long time, and soon went to Britain to study for a doctorate. After returning to China, he has been teaching in universities and geological research institutes, and has also represented the president of Central University. After the founding of People's Republic of China (PRC), Li Siguang served as vice president of China Academy of Sciences and minister of geology. 197 1 year, died in Beijing.

1926, Lu Xun left Beijing. Ten years later, he died in Shanghai because of illness. In contrast, Yang Yinyu's ending is even more tragic. At the beginning of 1938, she died under the butcher's knife of the Japanese invaders.
