Judging from the official authoritative policy documents related to academic misconduct, the Ministry of Education's Measures for Preventing and Handling Academic Misconduct in Colleges and Universities did not mention this kind of behavior, let alone define it as academic misconduct.

Take the rules of duplicate checking system as an example, no duplicate checking system will compare the repetition rate of one sentence and another sentence of the same paper. From this perspective, this kind of repetition is no problem.

Although there is no problem with this kind of behavior, P.S. had better try to say something fresh from the academic level.
