The postgraduate education system is 2.5 years, and the flexible education system is implemented, allowing graduate students to complete their studies in two stages. The longest study period is 4 years, of which the course study time is about 40 weeks, and the total credits required to be completed are above 35 credits. It is the second academic year to attend academic seminars and courses on situation and policy. Master students with interdisciplinary and equivalent academic ability must make up more than two basic professional courses at the undergraduate level, and the credits of the make-up courses are calculated, but they are not within the required credits that master students should complete.
