Héshùn
Heshun lies high in the Taihang Mountains of eastern Shanxi, near the upper reaches of the Qingzhang River. Its hills and passes form a barrier between the Shanxi interior and the plains to the east. The county belonged to Liaozhou through the Jin, Yuan and Ming periods, and its gazetteers describe a landscape of mountains, streams and frontier roads. The Huangyu Ridge east of the county marked an important passage towards the neighbouring plain.
