Xi 'an University of Arts and Sciences Auditorium

You should find a seat in Wei Zi Building (that is, Electronic Mall Station), then cross the intersection and go straight to the north gate (far from the auditorium), and then turn left to the east gate (near the auditorium).

Or don't get off at Wei Zi Building, and get off at the south gate of the school. The conductor should remind you that it's in the west as soon as you enter the south school auditorium! Taibai South Road 168!
