Checking the duplicate of a paper does not necessarily check the contents of 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 according to the duplicate checking system used.

When writing a thesis, you should avoid directly copying or translating online content, especially from social platforms such as Zhihu. If you need to quote online content, you should quote and mark 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 systems such as HowNet and paperfree to check the paper in advance, and make corresponding modifications and adjustments according to the test results.
