Yìngshān

Yìngshān lies in northeastern Húběi near the passes leading toward the northern plain. Under the Suí, neighbouring Píngjìng County was absorbed into Yìngshān in 606. The county remained part of the administrative landscape of Suízhōu through the Míng and early Qīng, amid hills and valleys on the approaches between Húběi and Hénán.
