Correct citation format: before duplicate checking, you need to mark the citation part of the paper and use citation symbols, so that you can mark part of the citation in advance and it will not be considered plagiarism. At the same time, the paper will have certain format requirements, and the author can directly modify the paper according to the requirements. When the paper is copied, the cited part of the article will be automatically deleted. If the quoted content is in the correct format and the number of words is small, the part will not be detected.

Appropriate citation content: the citation content needs to be included in the comparison database of the duplicate checking system, and only in this way can it be correctly identified and calculated. However, it should be noted that the content quoted should not be too much, otherwise it may be considered plagiarism. Generally speaking, the content quoted should not exceed 5% of the total number of words in the paper.

Citation source authority: the citation content should come from authoritative academic journals, research institutions or well-known scholars' research reports and works. These contents are generally considered to be of high quality and credibility, and will not be regarded as plagiarism.

Reasonable citation method: Besides the content itself, the citation method is also very important. If you simply copy and paste or quote other people's research results in large chunks without proper rewriting and integration, it may be considered plagiarism. Therefore, when quoting, it is necessary to make appropriate rewriting and integration, and combine the quoted content with one's own research to form a coherent whole.

It should be noted that different schools and periodicals may have different requirements and standards, which need to be adjusted and revised according to the actual situation.
