The reason why Nanguang Communication University is considered as three books may be its history and orientation. The university was formerly known as Nanguang College of Communication University of China. It is an independent college founded by Nanjing Meiya Education Investment Co., Ltd. and Beijing Broadcasting Institute (now China Communication University).
Because its school-running level is undergraduate level, it belongs to the third batch in the admission batch, so it is called three books by some people.
