Because the database is different, it needs to be retested and changed according to the test results.

Not to mention the difference between this year and next year, that is, the results of duplicate checking of papers last week and next week may be different, because the database of duplicate checking system will continuously include new contents to ensure the accuracy of duplicate checking results. The first draft can be tested on Wanfang, paperpp, paperquery and other websites. After the modification is qualified, it can be tested again in HowNet. If it is qualified, it is best to submit it to the school immediately, and don't wait too long, otherwise the repetition rate may rise again when the school audits.

There is also a bigger "trace", which is included in the HowNet database as a data source for comparison. As mentioned above, the undergraduate databases specially included by HowNet include "Joint Comparative Database of College Students' Papers" and "Joint Comparative Database of Academic Papers". The graduation thesis can be used as long as it is checked in HowNet. Including, if you postpone graduation until next year, the proportion of similar articles can reach 100%, because compared with the last included article, such "traces" also avoid students, and do everything possible to strive for a smooth graduation in the first year, so there is no need to postpone graduation until next year.
