There are roughly three possibilities for two registration codes. One is a Sino-foreign joint venture major with high tuition fees and different teaching methods. The second is branch schools and off-site campuses. There is a certain gap between branch schools and other campuses in terms of school-running level and management system, such as Harbin Institute of Technology (Weihai), Shandong University (Weihai), Southwest Jiaotong University (Emei Campus), Southwest University (Rongchang Campus), Northeastern University Qinhuangdao Campus, China Youshi University (Beijing) Karamay Campus, etc. There is also the same university, which was later independent, such as China Youshi University (Beijing), China Youshi University (East China), China University of Mining and Technology, China University of Mining and Technology (Beijing), China Geo University (Wuhan) and China Geo University (Beijing).
