Caojiadu is located in the northwest of China and southeast of Suzhou River. In the 18th year of Guangxu in Qing Dynasty (1892), Chinese businessmen bought land to build oil tankers, and later set up silk reeling factories and flour mills, which enabled a large number of workers to settle nearby and set up houses and shops on both sides of the road. Due to its proximity to Wusong River and convenient water transportation, wealthy businessmen and tycoons have set up foreign yarn factories, weaving factories, feather factories, oil factories, light bulb factories and Hong Chengtai and Xu Tongchun grain shops here, and the market has gradually developed. Later, due to frequent wars, the number of residents who moved here to take refuge increased sharply, shacks developed rapidly, and businesses extended from north to south and from west to east, forming a commercial market town in western Shanghai. A large number of shops such as rice, oil, sauce, firewood and small department stores have been opened in the area. Spring Garden Tea House, Bathroom and Bathroom, Huxi Zhuangyuanlou Restaurant, Wukun Mountain Flower Shop and Qiantaixin Non-staple Food Store opened one after another, and Huxi Cinema Huaguang Theater opened, with a prosperous commercial market.

After the liberation of Shanghai, a large number of working people lived in Caojiadu area, and commercial outlets gradually expanded to surrounding areas. Caojiadu is located at the junction of Jing 'an, Changning and Putuo, among which Wujiaochang is the intersection of five roads.
