Huangpu River is one of the "Three Rivers" waterways where Taihu Lake flows into the sea in history. It was called "Dongjiang" and "Hengliaojing" in ancient times. Originated in Taihu Lake, it flows eastward to Dianshan Lake in Qingpu District, and its upstream reaches are Gangkou, Bahe, Xietang, Hengliaojing and Liao Jing, until it reaches below Mishidu in Songjiang, which is called Huangpu River. It flows northward at the mouth of Zoujiasi in Minhang District, accepts Wusong River (Suzhou River) at Baidu Bridge in the center of Shanghai, and joins the Yangtze River at Wusong Mouth. In the Southern Song Dynasty, it was recorded that it was once called Huangpu Tang, Huangpu Port, Huangpu and Great Huangpu, and in the Qing Dynasty it was called Huangpu River, also called Huanglongpu, Huangxiepu and Chunshenpu. Huang Xie Shop, Chunshen Shop and other names are all named after Huangpu River attached to later generations was dug by Huang Xie of Chunshen Army during the Warring States Period. At the beginning of Ming Dynasty, the mouth of Huangpu River was blocked due to the serious siltation of Wusong River. At that time, Minister Xia Yuanji dredged tributaries on the north and south sides of Wusong River, diverted Taihu Lake into Liuhe River and Baisong River directly into the Yangtze River ("Zhasong River enters Liu Liu"), and dredged Fanjiabang in the northeast of Shanghai County (that is, the section of Huangpu River from Baidu Bridge to Fuxing Island today), so that the Huangpu River flowed northwest from Fuxing Island to Wusongkou into the Yangtze River. Later, Harry presided over the construction of a sluice port on the east side of Jinhui Port of Gudong River (then known as Hengliaojing), which made the mouth of Zoujiasi, where most of the Dongjiang water was located before the sluice port, turn north to take a small and medium-sized waterway then known as Huangpu and flow northward into Wusong River, which washed away the riverbed in the lower reaches of Wusong River and completely solved the siltation problem of Wusong River. Wusong River, one of the "Three Rivers", has also become a tributary of Huangpu. Today's Huangpu River was formed after the water from Hengliaojing flowed northward. At the same time, only a small amount of incoming water directly enters the sea through the old waterway, which makes the lower reaches of Gudong River continuously silted. Later, this section of the river was also called Zhagang. Later, with the widening of the Huangpu waterway, the name of "Dongjiang" was changed to "Huangpu".
