First of all, both of them obtained their degrees or obtained the establishment through non-process methods. As a "cross-knowledge doctor", Zhai, as a doctor, does not know the knowledge network necessary for writing a thesis, which makes people doubt the reliability of his thesis and the authenticity of his degree. Finally, in the inquiry and investigation, Zhai's academic misconduct was confirmed, which also shows that Zhai's degree was obtained through non-process methods. As a "boyfriend in the system", Zisi incident was madly forwarded on the first day of the publicity period, which made a large number of people who were also trying to compile the news find clues, found that they did not participate in the interview, and there was no evidence to prove the authenticity of their interview. Finally, although the National Theatre issued a statement to speak for it, Zisi was in chaos in China, and in order to minimize losses, it issued a statement to withdraw from the compilation. But in fact, its nature is the same as Zhai. After the word "quit" was announced, in fact, he simply cancelled the previously registered company's admission requirements for "undergraduate and part-time staff" in combination with the National Theatre. We know that he has long been disqualified from participating in the compilation, because he has previously registered a company in his own name and is already an on-the-job employee as the nominal boss of the company, but his appearance in the compilation is definitely problematic.

Secondly, think carefully about the similarities between them. They have got the "cake" that most people desperately want. They are not reserved, but they still publicize, and finally their behavior will be made public. Zhai repeatedly showed off his doctorate to the public, but was stumped by HowNet. These four words were widely publicized on the first day of the publicity period and were finally withdrawn by the evidence.

To sum up, I think the four-character incident and Zhai incident are of the same nature, both of which belong to abnormal degree/admission preparation and should bear the corresponding consequences.
