1, restatement. If there are 13 words in a sentence in the paper that overlap with the content of HowNet database, it is considered plagiarism. So plagiarism that has been detected can be repeated, and the same meaning can be expressed in another way. For example, "the report of the 19th National Congress of the Communist Party of China emphasized that it is a major principle of our party to coordinate development and security, enhance the sense of hardship, and be prepared for danger in times of peace.

2. Use intelligent translation tools. Translate the plagiarized content into English with Baidu or Google, then translate English into Spanish or other languages, and finally translate it into Chinese, so that the sentence structure of the original text can be disrupted and plagiarism can be avoided simply by rearranging the sentences.

3. Picture method. For example, there are a large number of program segments in some engineering papers, which are difficult to be modified by the first two methods, so this part of the content can be placed in the article in the form of screenshots, and it is difficult to find out that it is in picture format when it is submitted to the school. Duplicate checking software can't identify this part in the detection process, so it can successfully avoid duplicate checking.
