Sanxiang has a long history, with human footprints as early as the pre-Qin period.

More than 2,000 years ago, people lived near Sanxiang Ancient River. There are not many local works, mainly foreigners. In the war since the Southern Song Dynasty, the Central Plains people and Jiangnan people moved southward on a large scale, which increased the population in China. In the Ming Dynasty, agriculture and fishery in Xiangshan gradually developed. In the Qing Dynasty, especially after the opening of the five major trading ports in China, commerce flourished and the population living in Xiangshan increased. Since the founding of the county, the population has increased and decreased several times due to frequent wars, natural disasters and epidemics.
