But your personal plan is to return to China for employment. This is very simple. Look at the comprehensive ranking and brand of the school, and choose which one is louder. I have also had students who were admitted to both UM and Yale non-prestigious schools, and decisively chose Yale (higher overall ranking). Of course, it may also be a school with a better professional ranking and a better comprehensive ranking. A few years ago, some students accepted master's degrees in environmental engineering from Columbia University, University of Pennsylvania and Berkeley, and later chose Berkeley because of its high professional ranking and comprehensive ranking. I came to the United States to study PhD because of the possibility of livability, so Florida is the best choice for the elderly.
To sum up, from your own planning point of view, Columbia University's SPS is the most suitable choice.
