When citing the same document, you can use non-numerical citation methods (such as author's surname and publication year) or numerical citation methods (such as contribution number). Non-digital citation method is more clear when citing different documents, but when citing the same document, it is necessary to make sure that it is the same document to avoid ambiguity. Digital citation method can identify the cited documents by simple digital numbering, which is concise and clear, but it needs to number the documents several times to avoid confusion.

No matter which citation method is adopted, the same citation format and specification should be followed when quoting the same document to ensure the accuracy, standardization and readability of the citation. In addition, when quoting the same file for many times, we should pay attention to the following aspects:

1. When citing the same document, keep the consistency of citation information, including author, title, publication year, publishing house, page number, etc. To ensure that all citations of the same document in the paper can be correctly located and retrieved.

2. Avoid relying too much on the sentence pattern and expression of the original citation when quoting the same document repeatedly, and re-express it in a new context, which is consistent with the previous citation information.

3. When citing the same document, we should try to avoid too many repeated citations and too many citations of the same document in the paper. We can use the method of summarizing citations, such as sorting out multiple citations and giving information such as contribution number, page number or paragraph number at one time.

In short, citing the same document is a common situation in paper writing. Reasonably quoting and handling the quotations from the same document can improve the quality and readability of the paper.
