I live in Qingdao University and have never heard of 33 1. My advice to you is to take 3 16 (passing by Qingdao University, but not the east campus of Qingdao University) or 32 1 (ending at Qingdao University of Science and Technology). Because there are many buses, you can get off at Qingdao University, then transfer to 125 and sit at the end. You can also just take 32 1, which is a long route. Get off at Qingdao No.2 Middle School Station (belonging to Laoshan District). There may be more buses to Haida University, but I haven't tried it. I don't know where the south gate is. Anyway, when you arrive at Haida University, you can just go directly to the campus and ask, but I remind you that if I follow my advice, the landlord will have to prepare for half an hour from the time when he arrives at Haida University (which is relatively comfortable) before he can walk to the front of the building of Foreign Languages Institute. Although I have not taken IELTS, I have taken BEC, TOEFL and IELTS in Shanghai University.

There is no decent hotel nearby, but there should be a small hotel, which is still under construction, a little more desolate than the urban area.

If you go to Laoshan, you can only suggest that you start early in the morning, so that the time will not be too hasty. It seems that you took 3 1 1 or 1 10. I forgot the details. I climbed two years ago, and it took a long time.

I hope it will help the landlord and wish you success in the exam.
