It depends on which college. General freshmen, including national defense students, will live in the south campus for one year. When the sophomore moves back to the North Campus, the national defense students will collectively live in the national defense student apartment. It seems that there are almost no national defense students in the college who are headquartered in the south campus. If there are, they will be in the south campus, but they are generally in the north campus, which means it depends on which campus the college headquarters is in!
