1. Use citation management tools: Use citation management tools (such as EndNote, Zotero, Mendeley, etc. ) can help you manage and insert references easily. These tools can usually automatically generate the correct quotation format and provide real-time quotation suggestions when you write.

2. Use APA, MLA or Chicago style: Choose the appropriate citation format according to your academic field and publishing requirements. For example, APA format is suitable for social sciences, MLA format is suitable for humanities, and Chicago format is suitable for historical and literary studies.

3. Citation: In the text of the paper, when directly quoting the research results of other authors, it is necessary to enclose the original text in quotation marks, and indicate the author's surname and publication year in the quotation. For example: "As Smith (2020) said,' Global warming has a significant impact on agricultural output'."

4. List in the list of references: At the end of the paper, provide a detailed list of references, and list all the cited documents according to the selected citation format. Make sure to provide complete information for each reference, including author's name, publication year, article title, journal name, volume number, issue number (if any) and page range.

5. Check the accuracy of citation: After the paper is completed, carefully check every item in the reference list to ensure that all the cited information is accurate. If mistakes are found, correct them in time.

6. Follow the principle of academic integrity: ensure that all references in the paper are true, and don't deliberately forge or tamper with the data. If plagiarism is found, you may be severely punished academically.
