鄂尔多斯高原
The Lüliang Mountains are a mountain range in central China, dividing Shanxi's Fen River valley from the Yellow River. The range forces the Yellow River southwards on the eastern side of the Ordos Loop but tapers off to the south, where the Fen turns west to join the Yellow River before the Qin Mountains turn the combined river sharply eastward at its confluence with the Wei at Tongguan in Shaanxi.
