Qīngshuǐlǎngshān

Qingshuilang Mountain forms a long, wooded ridge in western Yunnan. Running roughly north to south, it rises between the Yangbi and Bi river valleys, part of the western branch of the Yunling ranges. Its high peaks descend into steep-sided valleys, where streams cut through the mountains toward the Lancang River. Salt wells along the Bi River made the country on its western side valuable to the communities that lived among these ridges.
