Generally, 5-8 journal articles are appropriate. But different journals have different specific requirements. Some journals have regulations that it cannot be less than or more than how much, and may also require the number of years of references. There are still some journals that are not stipulated, and the number of articles is not required, so it is not necessary to have them. If you contribute, try to add references, and the article will be more academic. In addition, according to the journal you want to contribute, ask the editor of the manuscript directly to know the specific requirements.

Papers can be published without references, even if they are published. The first reason is that the magazine is not rigid, and the second reason is that the editor directly deletes references because of layout reasons. The most important thing is to combine the reality with the characteristics of magazines and make reasonable arrangements. Br> References refer to a book or a paper as a whole in the process of academic research. The cited documents have been noted in the notes and no longer appear in the following references. Literally, a reference is a document cited in the writing process, such as an article or a book. However, according to the definition of GB/T 77 14-20 15, the reference after the text refers to the relevant literature information resources cited for writing or editing papers and works. According to the requirements of China Academic Journals (CD-ROM Edition) Retrieval and Evaluation Data Standard (Trial) and China Social Science Journals Arrangement Standard (Revised Edition), many publications distinguish between references and annotations, and define annotations as "words that further explain or supplement a certain content in a text", which are listed at the end of the article, separated from references or placed at the footer.
