Shàngjīn

Shàngjīn lies near the border of Húběi and Shǎnxī, where the Jīnqián River reaches a small plain on its way to the Hàn. A county was established here in early imperial times, and the walled town guarded an approach through the mountains. During the late Míng, the rebel leaders Lǐ Zìchéng and Zhāng Xiànzhōng used this country as a base.
