If you want to keep it simple, just walk through Chifeng Road, at the gate near siping road (the south gate of Tongji University, which faces south, because there are two doors in this place, and the gate of the south campus is also on Chifeng Road, but it opens to the north), enter the door directly, walk past the right hand side of the hospital, and you will find the College of Life Sciences, a new building with great momentum, and then go straight along the entrance road until you come to the end.
These two majors are in the school headquarters, belonging to Yangpu District, and there are Finance University and Foreign Languages College nearby.
