Harbin Institute of Technology (Weihai) is a campus of Harbin Institute of Technology, and Peking University Medical Center is also a part of Peking University. Their enrollment plan is unified, but they are divided into two campuses to enroll students separately. For the convenience of enrollment, they applied for independent enrollment codes. They are not independent schools, so they belong to the category of "branches of institutions of higher learning".
