I used to share one dorm with other four girls when I was still in my old College, and it is actually a very common thing that five or six students share one room in China.
I think that my roommates are really nice persons on the whole. But sometimes the things went wrong. For example, if one of us hadn’t talk with others more than two days, the others always thought that she must be angry with someone of us. But the truth was that she needed only a little space for herself. When those things happened, we would try our best to work them out. But finally, in the last year of my college life, our friendship was totally broken. Now I have missed my roommates and our friendship, but I have also realized how important the self-space is.
