duplicate checking of papers may not necessarily check the contents in Zhihu. This mainly depends on whether Zhihu's content is collected by the paper duplicate checking system. Different paper duplicate checking systems contain different databases, so it is necessary to judge whether Zhihu content is included or not according to the duplicate checking system used.

When writing a thesis, we should avoid directly copying or translating the content on the Internet, especially the content from social platforms such as Zhihu. If you need to quote the content on the Internet, you should quote and annotate it appropriately to avoid the paper being detected as plagiarism. At the same time, in order to ensure the accuracy of the duplicate checking results, we can use the duplicate checking system to check the papers in advance, such as HowNet and paperfree, and make corresponding modifications and adjustments according to the test results.
