Langshan (崀山) is a Danxia mountain in Xinning County, in the southwest of Shaoyang, its red sandstone carved into table-topped peaks, pillars and narrow lanes. Legend says the emperor Shun, passing south, praised the mountain and gave it its character, which is read as a good mountain. It is a rare large Danxia landform, 108 square kilometres in extent, gathered into six scenic areas: Bajiao Fort, Chilli Peak, the Tianyi Lane, the Fuyi River, Zixia Gorge and the Tiancheng natural bridge. In 2010 it joined five other Danxia sites across China as the China Danxia World Heritage property. The poet Ai Qing wrote that its scenery rivals Guilin's. A national geological park and a 5A scenic area now stand over the valley.
