Go straight from the main entrance of the school, (it's a block away, but it's all gardens) to the district government (Zhengyang Road) to do 502, get off at the terminal Qingdao Municipal Government, and walk south to Hong Kong Road, and you will see it.

However, there are many 502 people, and it takes more than an hour to get to the city. I suggest you do 502 at the departure station of Great Wall Road, 6 13 at the RT Mart side of the school gate, and just get off at Great Wall Road and cross the road. The fare for 502 is 2 yuan, 6 13 yuan. I hope I can help you!
