Among the three schools, Hainan University is 2 1 1, with the largest hat, but in fact the worst strength. 20 17 in the fourth round of subject evaluation, Hainan University has only two B's; Yangzhou University has an A- and five B's, Xiangtan University has three B+ s and three B's.
If you care about the hat of 2 1 1, you can go to Hainan University. Xiangtan University and Yangzhou University are actually very good, if you don't care about the 2 1 1 hat.
The campus environment of Hainan University is still good.
