Minor is generally a minor field or discipline that students pay attention to, and it is usually a supplement to the major. When studying science, students can not only choose physics, mathematics and other majors under the Faculty of Science as minor majors, but also choose majors from the Faculty of Arts or other colleges as minor majors. Major is necessary, and minor can be chosen according to interest or future development needs, but some projects of some majors also require students to study a specific minor.
