Division system is an open interdisciplinary organization, which goes beyond the college level. In comprehensive universities, different colleges with similar disciplines are integrated into a "department".
University has two meanings. The first is a college smaller than a university, usually a college with relatively few disciplines. Under such colleges, secondary colleges and departments can be established. The second is a secondary college established in a university, which generally includes several similar disciplines or departments.
Department is a teaching management institution set up by colleges and universities according to the nature of specialty. The level is generally lower than that of colleges, and a department generally has one or several majors with similar nature. Generally, two or three departments form a college, and there are also larger departments directly under the college.
Different scales:
Generally speaking, the scale presents the situation of department > college > department.
Chinese and foreign universities have different settings:
The division system originated in Europe, and most famous universities in Europe, America and Japan adopted the division system, gradually forming an academic organization structure similar to university-department-department-research institute.
In China, there are few departments in mainland schools, and most of them are academic organizations of universities, colleges (directly affiliated departments), departments and laboratories.
