References cited in the text of the paper should be marked in square brackets with Arabic numerals 1.2.3 in the form of labels in the upper right corner. When citing multiple documents, the serial numbers of individual references should be listed in square brackets, and each serial number should appear in comma form. If it is a continuous serial number, then the serial number can be marked.

Footnotes are mainly used to explain numbers, a sentence or a word in detail, mainly when the explanation of a word is unclear or the detailed explanation of a word affects the reading of the article.

Matters needing attention for users to cite references:

1. The basic principle of selecting references is to be closely related to the theme of the paper, not to be divorced from the paper, and to serve the theme demonstration of the paper. Some students habitually put all the collected references in order to increase the total number of words in the paper, which will lead to the overlapping of materials and themes and affect the expression of the theme of the paper.

2. The selected references are not typical enough to be widely known. When sorting out and selecting references, we should choose some characteristic and representative ones, so as to reveal the essence of things more effectively, and at the same time, we should consider whether the selected references are outdated.

3. The recommendation letter should be more authentic. Only by being true and objective can we better reflect the true nature of things and make the arguments of the paper stand firm and convincing. When quoting references, we should pay attention to the contents of the references, and every detail cannot be wrong. But also accurately extract and write numbers, and you can't make mistakes because of carelessness.
