Three books are good, running the south campus of Zhengzhou University and the north campus of Zhengzhou University of Technology (formerly Zhengzhou University of Technology). They are software college and software technology college, majoring in computer science and technology, and awarded Zhengzhou University graduation certificate and engineering degree certificate. It's good to want to study. Sias and Shengda cooperated with Zhengzhou University, not the three of them.
