Why are some colleges called universities (Luoyang University, jiaozuo university) and some schools called colleges (Sichuan International Studies University,)?
Because these universities were established in accordance with university standards at the beginning of their establishment, they were affected by the school upgrade and were not formally included in undergraduate education. In fact, some schools have good educational strength, such as Luoyang University, which was successfully upgraded to Luoyang Institute of Technology in 2007 and 2008.
