Tàihángshān

Mountains rise west of the Fen River basin, forming part of the long Lüliang range of Shanxi. Their ridges run broadly north to south, separating the Fen valley from the country toward the Yellow River. Deep valleys cut through the uplands, and the mountains' slopes form a rugged edge to the more open basin around Taiyuan. The range stretches far beyond this section of high ground.
