How to add footnotes: First, open the WPS document, move the cursor to the place where footnotes need to be added (usually before punctuation marks), and click "Reference" and "Insert Footnotes". Methods of adding references: There are two ways to add references, and you can choose according to your needs. One is that the citation part of the article should have corner marks, and the corresponding references should be listed at the end of the page, that is, endnotes. So how do you insert endnotes? The method of endnotes is similar to footnotes. Also, the cursor stops behind the text that needs to add an endnote, click "Reference" of WPS, and then select "Insert Endnote".
