First here is the chinese version for ur question^^ 1)“Today , one of my Chinese male friends asked "Why is it that men and women live together in American college dorms?"今天，我的一个中国男性朋友问我，“为什么在美国的大学，男女可以合住?(and you can also use"混寝"instead of the word"合住",it particularly refers guys and girls live together) 2)I replied "Is this strange? Is it not common in China?"我回答道，"这很奇怪吗？这在中国不常见吗？"(or you may make the 2 sentences into one,then it'll be"这在中国很奇怪吗？"although here u omit "common",but the phrase still indicates ur furthur question"Is it not common in China?",so u can choose any one as u like) 3)He went on to say that "In China, men and women do not live together in student dorms. They are separated."他接着说，"在中国，在大学里男女不能住在一起。他们分开住。"(went on=接着and usually we say"co-ed" as"男女",not "女男",this is just an idiom,no specific reason lol) Now is the answer for ur question^^ Here in China,co-ed dorms is rarely seen in universities.在中国，大学里几乎不存在男女合住。 Generally we seperate guys and girls dorms.一般男女都是分开住。 The roommates are uaually from the same class,or maybe from the same major.But sometimes maybe from different major or faculty.But the rule is still no co-ed.一个寝室的室友可能是一个班的，也可能是一个专业的。但有时候也可能是不同专业或是不同学院的。 Well u still got chance to live as co-ed dorm.不过你还是有机会选择男女混住。 You can live outside the university and rent a room as a co-ed dorms.你可以在校外租房子，选择男女混住。 But anyway in some university,probablly u have to get the approval for living outside the university,coz u r arrenged into a dorm since u entered the uniersity.But you can cancle it later.但是在某些学校，你可能先得得到学校批准才能在校外住，因为从你入学起就已经被安排好宿舍了。但是（如果你想住校外），你可以稍候选择退宿。 Well i once lived in university with a couple of girls through 4 years lol^^

Well i'm not sure if i understood u right..lol, here in china,guys are not allowed to go inside girls' dorms unless they signed their names at the supervisor's place at the first floor when they entered,and pretty much the same with girls going inside guys' dorms. So there's no way that guys can live in the same room with girls,barely in the same building i would say.So..hope this would help u to understand ^__^

在中国，男女生不会住在同一间宿舍，但在一些学校，会有一些男女生住在同一栋宿舍楼（比如我们学校），但男女生上宿舍的楼梯口是不一样的，男女生就算住在同一栋宿舍楼也基本不会相遇。

lol I know my Chinese is awful. But I have to keep trying, right ^^!! Ok, Here is the English version of that statement... “Today , one of my Chinese male friends asked "Why is it that men and women live together in American college dorms?" I replied "Is this strange? Is it not common in China?" He went on to say that "In China, men and women do not live together in student dorms. They are separated." 我的问题。。。 Can anyone talk about this more? Are there co-ed dorms in China and my friend just never lived in one? Are co-ed dorms common in colleges and universities in one part of China rather than another? Do Chinese people have a choice if they want to live with guys or girls in the dorm? What was your experience? (请回答中文。或者中文和英文。不仅英文。谢谢！^^） "co-ed"=men & women
