Tianjin Airport and civil aviation university of china are geographically adjacent. It's really 10 minutes' journey from the early airport terminal to the north campus of Civil Aviation University, because it's on the same road. But the year before last, because the terminal of Tianjin Airport was relocated (to the end of Kim Road), vehicles had to bypass the outer ring road to enter the Civil Aviation University. Taxis at the airport were more expensive than taxis in urban areas 1 yuan (about 30-40 yuan per kilometer).
The former old terminal building is now a freight airport!
If you walk from the new terminal, you need to cross an area without roads, not too far!
