Nánlǐng
The Nanling forms a great belt of mountains between Hunan and the lands to its south. In this part of the range, the Jiuyi Mountains extend from the Mengzhu Ridge, their nine peaks rising above the wooded slopes of southern Hunan. The highest is Shunyuan Peak. Streams born in these mountains feed the Xiao River and tributaries of the Pearl River, separating waters that eventually find their way to different seas.
