The system is congested in graduation season, and there may be delays, while some students often revise their papers later, usually before 1 or 2 am, and they will give a report that evening. On the contrary, there will be reports after 7 am.
In the graduation season, basically more than 98% universities in China will choose to use China HowNet system to detect the repetition rate of students' master's thesis.
However, the channels of China HowNet system are limited. If there is a peak of duplicate checking, a paper may take several hours to check, but for students, time is very limited. Therefore, if students can submit their papers to China HowNet system for testing in the early hours of the morning, they will be at the forefront of the team as soon as possible. The next day, when the duplicate checking channel of China HowNet system is opened, they can also give priority to duplicate checking of papers submitted by students in the middle of the night.
