With the continuous expansion of Shanghai, there are more and more new roads and new road names. After 1952, the municipal administration department inherited the tradition of naming the place names of China provinces and cities in Shanghai Road, formed a set of relatively perfect naming principles, and named the place names of relevant provinces and cities according to the direction of the road to be named. Yangpu District is located in the northeast of Shanghai. The road names are named after the place names of Jilin and Liaoning provinces, including Songhua River Road, Anshan Road and Benxi Road. Putuo District is located in the northwest of the urban area. The road names are mainly named after the place names of Shaanxi Province, such as Yichuan Road and Zhidan Road, while a few use the place names of Sichuan Province, such as Jinshajiang Road and Daduhe Road. Changning District is located in the southwest of the city, and the road names are named after the place names of Guizhou Province, including Zunyi Road, Maotai Road and Anshun Road. Xuhui District is named after the place names of Guangxi Province, including Tianlin Road and Cangwu Road. The area along the Yangtze River in Pudong is named after the place names of Shandong Province, including Laoshan East Road, Weifang Road and Wendeng Road (now Dongfang Road). After 1958, Wusong, Anting, Minhang and other industrial zones in the suburbs were developed. The road names around Shanghai Baoshan Iron and Steel General Factory, which was built in the late 1970s, were named after the corresponding provinces according to their locations.
