1. There are many colleges and universities in Guangdong, so the number of college students that can be absorbed is relatively large. Hunan and Hubei are underdeveloped areas, and there are few undergraduate colleges. Students have to work harder to get into a better undergraduate school, and the teaching quality is of course high.

2. There are also reasons for policy tilt. For example, Hainan, Tibet, Xinjiang and other places are backward areas in education, and the state will allocate more indicators of good schools, so it is easy for local students to go to good schools. The teaching quality is average.

3. Many candidates from Hunan go to other places for exams. They may have average grades in Hunan, but it is relatively easy to get a good undergraduate course in other places.

4. Colleges and universities recruit students for the whole country, and the difference lies in the enrollment indicators of various places. Compared with other provinces, Hunan and Hubei have fewer indicators and more candidates. Students don't study hard and schools don't work hard to improve teaching quality. It is not easy to get into a good university.
