For the spot check of the thesis, it depends on whether your school and education bureau will conduct spot checks on the graduation thesis. Generally speaking, even the papers of students who have graduated are likely to be spot-checked. If you only finish your thesis in a perfunctory way, you can graduate smoothly. If you are randomly selected, you are likely to have your degree certificate revoked. You went to college for a few years in order to have a diploma and a degree certificate, so that your education will be recognized. So don't risk writing a paper, or you may end up losing money.
In fact, no matter whether it is the paper duplicate checking system or other paper duplicate checking systems, the graduation thesis will not be included in the duplicate checking database immediately after duplicate checking, and it usually takes some time to be included in the duplicate checking database. After all, some people's graduation thesis will not pass after duplicate checking and needs to be revised. If included, the graduation thesis will have a higher duplicate checking rate in the second duplicate checking, so it will be included in the database of the duplicate checking system after a period of time.
