Like everyone else, I am curious about this question. At first, I also believed that this was true, but according to the relevant information, I thought this paragraph was fictitious.

First of all, it does exist in a sociology professor named Shen, but not in Peking University, but in Shanghai University. Therefore, if the author intends to prove the facts, there is no need to make mistakes in his university.

Secondly, I looked up Professor Shen's papers (maybe not all, but most of them should be counted), but I couldn't find the relevant contents mentioned in the novel. In addition, love in the revolutionary period should be completed around 1993, and there were few papers published by Professor Shen before 1993.

Finally, I think there is a very simple logic to explain, that is, if the author wants to prove that the content is true through Professor Shen's paper, then there is no reason to provide false information about Professor Shen; If the content is fictional, the author will create a virtual Professor Shen to enhance the "authenticity" of the novel.
