Is there a subway from Tianjin Medical University to Tianhuan Passenger Bus Station?

First of all, will you live the campus which is located at Qixiangtai Road? If yes, there is no direct subway. Thus you are advised to take bus no.879 and get to Xihu Road Bus Stop. Then walk south around 500 yards (470 meters) to find Tianhuan Bus Station.
By the way, it's ok for you to take the luggage on the city bus. Don't worry.
