If you don't consider taking exams or going abroad. I don't think there is much difference between the two schools.
It's just that English teaching in Australian University of Science and Technology may be helpful to some aspects of your work.
Besides, living in Macao can enrich your life experience and broaden your horizons. AUUST can also help you better integrate into the social life of Taipai City.
Beijing Normal University is actually not bad. Because it is a domestic school. If you want to take the postgraduate exam in China, I suggest you go to Beijing Normal University. But if you want to study abroad or go to Hong Kong for postgraduate study. Then I suggest you go to Australian University of Science and Technology to study.
Of course, it depends on which major you are interested in.
Some of my classmates also gave up Beijing Normal University and came to Australasia University. Of course, some people say that the Australian University of Science and Technology is not good, and Beijing Normal University is good. Everyone has a different opinion. It's mainly how you plan to do it yourself.
