Since then, the name "Suzhou River" has gradually become popular. However, at that time, the exact name of the river was not clear, and there were many opinions among the people. The annals of Shanghai, published in early 2004, really refers to the reach of Shanghai. Wusongjiang, formerly known as Songjiang. In the 15th year of Yuan Dynasty (1278), after Huating House was renamed Songjiang House, Songjiang was renamed Wusongjiang. After the opening of Shanghai, foreigners who came to Shanghai went upstream and found that they could reach Suzhou Fucheng by boat, so the English standard translation was "SoochowCreek". 1848, when Shanghai Daotai and the British Consul in Shanghai signed a treaty to expand the British Concession, Wusong River was first called Suzhou River in the official text, and later Shanghai folks gradually called it Suzhou River.
