Papers should still be cited, and then indicate the author, journal, serial number, time and page number. That's about it. The format must be unified. If you download a paper from China Paper Download Center, you should still indicate the original author.

The way to quote a document is to add comments to a paper when you open it from word. First, put the mouse cursor behind this sentence, click on the reference, and select Insert Endnote.

Direct reference refers to recording the referenced content according to the description in the original document. There are two specific formats: when the quotation is a complete sentence, if the original author's name, colon and quotation marks are complete, the last punctuation of the sentence is inside the quotation marks, and the quotation mark code is marked in the upper right corner outside the quotation marks.

It is to mark the data, opinions and conclusions separated from quotations. If the author's name is not written in the book or quotation, and only the relevant data or materials in the reference are quoted in the text, and the quoted part does not constitute a sentence, the document marking code should be directly marked in the upper right corner of the corresponding word or phrase. If the quoted content is expressed in words you understand, you should mark the document marking code before the dot in the upper right corner of the last word of these words.
