In academic circles, writing papers is an important way of communication. When writing a paper, literature citation is an indispensable part. Literature citation refers to the process of citing other authors' research results in papers. The purpose of doing this is to prove the organic connection between my research and the existing literature research, and to make the paper more credible, reliable and authoritative.

The purpose of citing documents in this paper is not only to prove that the research results are supported, but also to provide readers with additional information and reference materials. At the same time, quoting previous research results is also a kind of respect and recognition for other scholars. Citing the research results of other scholars not only recognizes the work of predecessors, but also shows that researchers are cooperating with others, absorbing knowledge and further developing.

Adopting the correct citation method and format can make it easier for readers to obtain references and facilitate their own similar research. When quoting files, you must follow specific formats and regulations. The most common citation formats in academic papers are APA, MLA, Chicago and Harvard. Which format to choose depends on the requirements of the author and publishing institution, as well as the practice in this field and discipline. In the process of writing, we must abide by the citation standards, otherwise plagiarism and academic misconduct will occur.
