How about the parking lot of Renmin University of China?
I often go to Renmin University to handle affairs, and I am familiar with the parking lot here. Usually my friends and I go in from the east gate, go to the school on the right and drive along the road. There is a parking lot in front of the dormitory building, which is not big enough to stop ten or twenty cars. The parking spaces here are generally full, and the place to go is near the international student building, so you have to make a detour to get there. This parking lot is also very small. That building should be called Koryo Hall. 10 cars can be parked on the sidewalk at the entrance, but there are relatively more parking spaces behind the opposite teaching building. The ground parking lot of the National People's Congress is scattered, but there seems to be only one underground parking lot, which is in Huixian Building. Basically, you go out to collect money when you enter the door, and few managers patrol.
