Can undergraduates use the graduation thesis of previous seniors to check the duplicate through HowNet?
Don't be so lucky, most of them can't pass. There is a "joint comparison database for college students" in the duplicate checking system of HowNet. If your senior's paper is duplicated in HowNet, it will be included, so you can't pass it. You can also take the paper directly and test it in advance on HowNet, and you can see it.
