Gushan Mt or “Isolated Mountain” lies in the Fuxian Lake of Chengjiang County. It was formerly called "Yinghai Mountain" that was linked to an isle beside by an iron rope bridge before the Ming Dynasty. In the late Ming Dynasty, the isle was submerged during an earthquake, leaving only Gushan Mt standing in the lake even today.
There used to be eight halls, five pavilions, three gloriettes and other architectures on Gushan Mt. In 1988 when Gushan Mt was developed into a tourist spot, special funds were appropriated to restore these architectures. And as the submarine cable system was put into operation in 1933, Gushan Mt became illuminated all night long, attracting numerous visitors.
