Fēihú

Feihu lies at the northern end of a narrow route through the Taihang Mountains, south of Yuzhou. The Feihu Pass was one of the great mountain corridors connecting the North China Plain with the uplands of Shanxi and the northern plateau. Hemmed in by cliffs, its winding road offered armies and travellers a passage through formidable terrain, making the entrance a place of lasting strategic importance.
