Abstract: Urbanization is an objective historical course. In this course, along with our country's further economic development and the further deepening of ref orm and opening to the outside world, in modern metropolis, village culture, ci ty culture, the various ethnic cultures and external cultures make together one picture of multi-cultures on the one hand, and on the other hand, the increasi ngly synchronization of these cultures through various conflicts also makes the metropolitan cultures take on a unified tendency. The "multi-" and "uni-" in the metropolitan cultures seem contradictory. Actually, it embodies the integ ration of the metropolitan multi-cultures.
