Cangshan Mountain is located in Tiantai County, Taizhou City, and is the main peak at the southern end of the Yunling Mountain Range. It is composed of nineteen peaks stretching from north to south, starting from Erhai Dengchuan in the north and ending at Xiaguan Tianshengqiao in the south.

Each pair of these nineteen peaks of Cangshan is separated by a stream that rushes down and flows into Erhai Lake, which is known as the famous Eighteen Streams.
