The Cangshan Mountain, also known as Diancangshan, is named after its verdant forests. The Canshan Mountain is a chain of the Yunlin Mountain of the Hengduan Mountains.

 Starting at Eryuan in the north and ending at Xiaguan in the south, it measures 42 km in length and 25 km in width. Overlooking the Erhai Lake in the east, the Cangshan Mountain is of great splendour and the scenary is unique. The Cangshan Mountain comprises 19 peaks, the highest of which is Malong Peak at an elevation of 4122 metres above sea level. It is snow-capped all the year round with a moraine lake on the summit. There are 18 brooks running down the 19 peaks. The snow-melted water between every two peaks rushes down and converges into the Erhai Lake.
  
The clouds over the mountains are varied and changeable. The most magnificent scenic wonders are the Husband-Yearning Cloud and the Jade-like Belt of Clouds. Every year when spring is changing into summer, a lone cloud will emerge over the top of Yuju peak, drifting up and down and casting glances about. Then , it suddenly turns into a dark cloud, resembling a woman I black. At this very moment, a gale will howl and cause rolling waves across the lake; this cloud is called "The Husband-Yearning Cloud." After rain in summer or autumn, a cloud will drift up slowly in the sky, stretching out kilometers around like a jade belt round the moutain; this is called "the Jade-like Belt of Clouds". The Yuyou tour route is a newly developed scenic area. Many scenic spots lie along the route: the Jianjin Cave, the Shimen Pass, the Hall of Avalokitesvara, the Gantong Temple, the Zhonghe Temple, the Qingbi Brook, the Butterfly Fountain and so on.
 
The weather in the Cangshan Mountain is varied and unpredictable. It is snow-white on the top,and the flowers bloom in profusion at the foot. The Cangshan Mountain is not only abundant in vegetation such as pine trees, furs, camellias, azaleas, orchids and medicinal herbs like Chinese angelica and banksias rose, but also in marble resources.
