1 Check the duplicate through the official duplicate checking system of the school or institution. Most schools and institutions provide official duplicate checking services, and students can upload their own papers through the official website or platform of the school or institution for duplicate checking. This can ensure the credibility and accuracy of the duplicate check results, and at the same time enjoy the preferential policies and services of schools or institutions.

2 Use a third-party duplicate checking website for duplicate checking. In addition to the official duplicate checking system of schools or institutions, you can also choose some regular third-party duplicate checking websites for duplicate checking, such as HowNet, Wanfang, papefree, papertime, VIP and so on. These websites provide duplicate checking services for papers, and students can choose the corresponding services according to their own needs. It should be noted that when using a third-party duplicate checking website, you need to choose a reliable website to avoid revealing personal privacy information, and at the same time pay attention to protecting the copyright and intellectual property rights of the paper.

No matter which method is used for duplicate checking, we should take duplicate checking seriously, avoid plagiarism and improper quotation, and ensure the quality and credibility of the paper. At the same time, it is also necessary to operate according to the requirements of schools or institutions to ensure the accuracy and credibility of the duplicate check results.
