Which bus should I take to Jimo Experimental High School?

Go east on route four! Get off near Warner Building, then walk north along that main road, turn right at the first crossing, walk about 150 meters, go to the gate of our school, turn left, enter the school gate, go straight along the road, go to student apartment A, and go in and find your dormitory, which seems to be 108. Explain it in detail.
