Introduction to Haimen Old Street: It is said that in the old days, old Haimen people came to Shanghai to make a living. After getting rich, they returned to Haimen and built European-style buildings according to the old Shanghai model. In addition, the street business was booming, " Hence the name "Little Shanghai". Therefore, the styles of the north and south of the old street are different. Most of the buildings in the north are European-style buildings. In the south, there are buildings from the Ming and Qing Dynasties first, and then from the Republic of China. After the founding of New China, the color of the Cultural Revolution was added, giving the old street distinctive characteristics of the times.
