When i was in NTU Hall, during weekends, the local students went home and the chinese scholars had a big orgy.
One day, the gal were so loud and then someone complaint and they got caught. 3M1F, why always M more than F for China? In the end, these people were just given warning like Sun Xu, never expelled because sex in hostel don't warrant expulsion.
Now, i heard even more hiong, foreign students smoking weed ($50 a stick) in local uni hostels.
