The specific format of references can be different according to the requirements of different disciplines and periodicals, but generally they should contain the above basic contents. When listing references, they should be arranged in alphabetical order according to the author's surname, and pay attention to the unity and accuracy of the format, such as punctuation, font, font size, etc.
In addition, when using other people's opinions or data, you need to quote the corresponding references in the text. Generally, the method of "author's surname+publication year" can be used for citation, as shown in (Smith, 2020). If you quote directly from others, you need to add a page number after the quotation, for example (Smith, 2020: 56).
Generally speaking, the listing of references needs to be cautious and follow the norms to ensure the academic rigor and credibility of the paper.
