Even regardless of tuition fees, you know that the University of Macau enrolled students in many provinces and cities a year or two ago, and its reputation and strength are not as good as those of some famous schools in Hong Kong.
The advantage is that the foreign language environment of the University of Macau is definitely better.
As the University of Macau is not recognized by the mainland 12, I personally suggest that you still consider the experimental class of Shanghai University. I want to study in the mainland in the future, and the platform of the experimental class is very good.
