More important comprehensive universities generally have psychology departments or psychology majors. This major is suitable for people with very strong, healthy and stable psychology, if their own psychology is not sound and stable. It is impossible to learn this major well. Therefore, although it is very popular, not everyone can apply for the exam, because being a psychologist or psychologist after graduation will contact a large number of people's psychological dark sides. If their psychology is not perfect, strong and unstable, it will be difficult to get rid of the influence of these dark sides.
