In my opinion, existing history of a city is similar to human life. However, it may pass away over one time. The first time is when time abandon it. The second time, maybe, when we leave it behind. “Saigon-Cholon urban historical museum” among formerly Southern Vietnam cultures, is a commemorative place to keep memories about reclaim and develop history of a unique urban model in the world “ Twin city ”. Saigon - Cholon are two representing cities of two ethnics Viet and Hoa (Chinese) in Southern Vietnam that had been reclaimed in 17th Century. In displacement years of Ming and Qing Dynasties in China, there are a large number of unobeyed Chinese left their country and some of them refuged in Vietnam. They were welcomed as one of Southern new land setters. Day by day, resident unit of Chinese was established and they had their own land and urban that called Cholon. They lived and traded with native Vietnamese in Saigon harmoniously. That interference created a new inherited native generation that includes excellent quality of both Chinese and Vietnamese. The boundaries of not only domain but also culture between Saigon and Cholon was faded gradually. A new city appeared in Vietnam.
