Technical secondary schools pay more attention to the study of professional knowledge. After graduation, they generally have mastered the professional knowledge of the corresponding major and can be competent for a professional job. Therefore, students usually go to work directly after graduation, and a few students will take one-time exams and enter colleges and universities.

Students who study in secondary specialized schools or some colleges and universities and graduate from secondary specialized schools (called secondary specialized students) belong to secondary specialized school education. Students mainly study secondary professional knowledge at school, and also study culture classes. Usually after the end of nine-year compulsory education, it has a progressive relationship with the professional knowledge of the corresponding professional colleges (junior college and undergraduate).
