鄂尔多斯高原
The Hexi Corridor (, Xiao'erjing: حْسِ ظِوْلاْ, IPA: ), also known as the Gansu Corridor, is an important historical region located in the modern western Gansu province of China, referring to a narrow stretch of traversable and relatively arable plain west of the Yellow River's Ordos Loop (hence the name "Hexi", meaning "west of the river"), flanked between the much more elevated and inhospitable terrains of the Mongolian and Tibetan Plateaus.
