Generally, when tagging references, click to insert references-footnotes and endnotes-at the end of the quoted text, and select only endnotes. References should be endnotes. Select Insert-References-Footnotes and Endnotes from the menu. Footnotes are notes at the bottom of a page of an article, while endnotes are at the end of the article. After opening, you can select the code, that is, the corner code. You can set the type and format yourself. Double-click the code to switch between articles and references.

In English input mode, enter [1] and select [1]. Press ctrl+shift++.

Place the cursor at the reference place, select Insert | Footnote and Endnote on the menu bar, select Endnote in the pop-up dialog box, and click the "Options" button to change the numbering format at the end of the document to Arabic numerals. After confirmation, Word inserts the reference number at the cursor and automatically jumps to the corresponding number at the end of the document. Please type the description of the reference, and add corresponding documents here according to the format of the reference description table. Reference signs require numbers to be enclosed in parentheses. So far, I haven't found a way to make Word automatically add brackets, so I need to add brackets manually. When a document needs to quote the same document many times, you need to make endnotes when quoting this document for the first time. When quoting this document again, click Insert | Cross-reference, select endnotes as the citation type, and the cited content is endnote number (with format), and then select the corresponding document to insert. Don't think it's done, we are one step away from success. The format of the paper requires that the references should follow the text, and the references should be followed by explanations, appendices and acknowledgements, while the endnotes of Word are either at the end of the document or at the end of the section, which do not meet our requirements. This solution seems a bit clumsy. First, delete all the numbers in the endnote text (it is unnecessary because of the wrong format), then select all the endnote text (reference text), click Insert | Bookmark, name it "reference text" and add it to the bookmark. In this way, all the references are collected. Create a new page titled "References" after the text and format it. Move the cursor under the heading, select Insert | Cross Reference, select the reference type as bookmark, click the reference text and insert it, thus copying the reference text.
