洋人街的边界是模糊、开放的，和周围老百姓的生活交织在一起。它虽低俗、混乱，嘈杂，藏污纳垢，却为低层百姓提供了暂时的“避难所”。周围的农民，小摊小贩，拾荒者，流浪汉，疯子各色人等都可以在洋人街找到生存空间，从而与那些干净整洁、戒备森严的，以理性和制度化来规范的，单调枯燥的现代化城市空间相区别开来。
Boundaries of Alien Street are open, and Intertwined with the lives of ordinary people around. Although it is vulgar, chaotic, noisy, and filthy, it provides a temporary “refuge” for the lower class. The surrounding peasants, stall vendors, scavengers, tramps, madmen, etc. can all find their own spots in Alien Street. thus Alien Street distinguishing Itself from those simple, tidy, modern urban spaces that are neat, guarded, and rationalized and institutionalized.
