All of Sandu belongs to the watershed of the Liu River which flows into the Pearl River. The Duliu River has its source in Sandu and flows into the Liu River. The county is rather mountainous with Karst landscape resulting in large locale temperature and climate differences. Antimony is mined commercially in Sandu.[1]
