References in the paper should not be written casually. Graduation thesis writing should be based on a rigorous and realistic scientific attitude. If others' achievements are cited, they should be listed in the references in the order in which they appear in the papers, and only the relevant works and papers cited or referenced in the form of labels should be listed. References should list the main references directly cited in the order in which they appear in the text. It is easy to mislead readers. Such a paper is easy to be found by reviewers when thrown out. Because reviewers are generally researchers in related fields. This mislabeling of references is likely to ruin a paper. Even if the content of the paper is good, it is very likely to be destroyed.
