Duplicate checking is a matching process, based on sentences. If a sentence is repetitive, it is easy to judge the repetition, so:

1) If it is indeed a classic sentence, it will be indicated by superscript endnotes in the references.

2) If it is a general quotation, add all the omitted subjects and predicates in a lengthy way. In the original sentence. Anyway, one more word is victory.

3) You can also use the horizontal knife method to remove some sentence elements and replace them with some pronouns.

4) Or use the foreign devil's method. If the foreign name in the original text is Chinese, it is directly used in English, and if it is English, it is directly used in Chinese. 5) If it is a quotation mark, don't use a period after the quotation mark. If you write a full stop, you will be plagiarized (although I think it is a quotation), so try to use a semicolon before the quotation ends. Some people put quotation marks after the period, which is wrong and should be put before the period.

6) Text can be converted into tables, and tables are basically impossible to copy. When words become graphics, tables become graphics, which are clear at a glance and will never be aware of repeated plagiarism.
