Rénxiàn

Renxian lies in the low country east of Xingtai, where streams gather in shallow lakes and marshes. Local gazetteers identified the southern lake near the county with part of the old Dalu marsh, while the northern lake was known as Ningjin Bo. In 1673 the magistrate Wang Yuanqi described and mapped the accumulated water, recording a landscape in which changing water levels shaped the surrounding land.
