Huangshan, literally meaning the Yellow Mountain(s), is a mountain range in southern Anhui Province in eastern China. It was originally called “Yishan”, and it was renamed because of a legend that Emperor Xuanyuan once made alchemy here. Vegetation on the range is thickest below 1,100 meters (3,600 ft), with trees growing up to the treeline at 1,800 meters (5,900 ft).
