CNKI query graduation thesis
The re-examination of the thesis originated from the arrangement issued by the state and the Ministry of Education in 2009 for academic misconduct in major universities. Of course, due to the need to check the papers, there are naturally arrangements for how to check the superiors.
At that time, China HowNet gradually matured, so the university took China HowNet as the comparative source of examination papers. So far, most colleges and universities have chosen CNKI as the duplicate checking system. Due to the long-term development, China HowNet has the most comprehensive information resource library in China.
