First of all, papers from top universities are indeed suspected of plagiarism. In fact, plagiarism not only appears in famous universities in China, but also in universities in other countries. For example, what I remember deeply is an academic fraud incident in Japan, which can be said to be a scandal of the whole academic community. Haruko Kobao, a graduate of Waseda University, worked in the Japanese Institute of Physical and Chemical Research and successfully published two important papers in the first-class academic journal Nature. It is said that there are Nobel Prize-level research results (non-science and engineering majors, in fact, I don't know much about them)

Secondly, whether the paper of Academician Zhan's team involves plagiarism is still being verified, and there is no conclusion. It should be based on the official notification, and it should not be rumored. According to the news published on the Internet, 25 papers of Academician Zhan were questioned on the American Pubpeer website, not only because of plagiarism, but also because of repeated data and incorrect experimental results. Academician Zhan also stood up and questioned directly, and actively communicated with his collaborators. Now this matter is still inconclusive, as long as it does not involve academic misconduct, there is no problem.

Moreover, in any case, there is suspicion of being blown out, and Academician Zhan is suspected of lax defense. Academician Zhan has both academic and administrative identities. Personally, I don't think Academician Zhan has the motive of plagiarism and forgery. But in science and engineering, the big boss usually leads the small boss, and there are a lot of graduate students under the small boss. However, if there is any achievement to publish a paper, the person in charge of the laboratory is usually a correspondent. So even if this matter is verified, it may be done by others in the team, but Academician Zhan, as the leader or correspondent of the team, must be responsible.

Finally, learning is a very rigorous thing, and people who engage in learning should cherish their feathers. Academic achievements, whether at home or abroad, should be published. These works published in your name are traceable. Therefore, if you plagiarize and falsify, it is actually a mine for your future academic path. If you want to make achievements in academics, you must cherish your feathers. Real gold is not afraid of fire.
