Among these 17 universities, 9 are 985 universities, 6 are 2 1 1 universities, and 2 are non-2 1 1 universities. The strength of these schools is uneven, some are caused by the large number of undergraduate master students, such as Huazhong University of Science and Technology and Wuhan University, and some are caused by too many undergraduate students, such as Zhengzhou University and Henan University.
