The primary reason is that the Ministry of Education has issued regulations that independent colleges must leave affiliated universities and move to new campuses to run schools independently. In other words, some private universities attached to public universities can no longer use campus facilities, libraries and teachers with public universities. The names of these private universities are often so-and-so colleges (for example, City College of Wuhan University of Science and Technology, zhixing college of hubei university, Wuhan University of Science and Technology is a university, and City College of Wuhan University of Science and Technology is also a university. The latter belongs to the former, and both of them often use some campus facilities and teachers.
