Take bus no.37 and get off at the bell tower.

Change trains at the bell tower, as follows:

Take bus No.7 to the south gate, then take the school bus and get off at the entrance of the dormitory area, and walk 200 meters to Building No.9.

Or take bus 2 1 and get off at the east gate and take the school bus, as above.

Or take bus No.5, 17, 20 and 30, and take the school bus to the north gate, as above. . .

If you want to walk back to Building 9 when you get to school, it's not far. . I suggest you take the No.7 bus to the south gate.

I can pick you up in my car if you like. You can pay 30 yuan or invite me to dinner. Ha ha.
