In the south of downtown Tianjin, there are five streets in the southwest of China: Chongqing, Dali, Changde, Munan and Machang. Tianjin people call it "the five avenues". There are more than 230 historic buildings and more than 50 famous houses in Britain, France, Italy, Germany, Spain and other countries. These historic buildings have various architectural forms, such as Renaissance, Greek, Gothic, Romantic, eclectic and the combination of Chinese and Western styles, and are called the World Architecture Expo Park.
