Plagiarizing other people's opinions: without changing the original intention, directly use the arguments, opinions and conclusions in other people's published documents, relay other people's arguments, opinions and conclusions, and delete, split, sort out or add them without quoting other people's arguments, opinions and conclusions.

Second, self-plagiarism: when writing a paper, don't quote, but use the content of the published literature (or I am one of the authors), or use the content of the paper I have already defended.

Third, multiple contributions to one manuscript: the same article is submitted to several journals at the same time. Papers should be sent to other journals within the statutory or agreed reply period.

4. Overquoting: Make the quoted part the main or substantial part of the article.

Five, all plagiarism: direct plagiarism of all or most of the papers published by others. After adding something to other published documents, such as adding some data or adding some new analysis. Use it after modifying the research object in other people's published papers, and don't quote it.

6. Repeated publication: use published papers in graduation thesis without quotation, or list published documents in general only in the references after the thesis.

Plagiarism: directly use the words in other people's published papers without any quotation. In other people's published papers expressed in words, although they are quoted, the words used are not quoted, or the font is not changed, or displayed in a specific arrangement.
