History is mainly a subject. History can only be regarded as a minor in today's China University campus, compared with science and engineering such as mathematics, physics, electronics, information and computer, and compared with liberal arts such as economics, law, management and even Chinese. In many comprehensive or normal universities, the history department is often one of the departments with the strongest teachers, because it was established early and will be interrupted in the end. So a paradox is formed: the newly established social science major has many students and strong reality, but lacks teachers; There are many talents in ancient history, but there are few students.

If we go to Europe, the huge history discipline system there will make us dumbfounded. The School of Historical Sciences of Free University of Berlin is composed of Friedrich-Menek Institute, Friedrich-Menek Library, Institute of Art History and Institute of Eastern Europe. The so-called "Institut" is Institut, which can be translated into college in English. Friedrich-Menek College is divided into ancient history department, medieval history department, modern history department and a historical geography teaching department. The "department" here is a German seminar, which is equivalent to a department or major in Chinese.
