Shanghai belonged to the state of Wu in the Spring and Autumn period. During the Warring States period, Shanghai was the fief of Huang Xie, the ruler of Chunshen in Chu, so it was called "Shen". During the Jin Dynasty, the area around the lower reaches of the Songjiang River was called "Hudou" because fishermen created the fishing tool "Hu" and the place where the river flows into the sea was called "Doudou", which was later changed to "Hudou". Later, the name was changed from "Hu" to "Hu", so Shanghai was called "Hu" for short.
The port of Shanghai was opened in the 23rd year of the Daoguang period (1843), and in the 25th year of the Daoguang period (1845), the area to the north of Yang Jing Bang in Shanghai County was set aside as a foreigner's residence, which was later formed into the British Concession. In 1848, the area around Hongkou was designated as the American Concession.
In 1956, after administrative restructuring, the number of Shanghai municipal districts was reduced to 18, with 15 urban and 3 suburban districts under the jurisdiction of the city. 1958, in order to adapt to the needs of urban development, the suburban counties of the Shanghai area belonging to Jiangsu Province were transferred to the city of Shanghai.
