Dōngníng

Dongning lies in the Suifen River valley, among the wooded hills of eastern Manchuria. An old walled site at Dachengzi recalls the kingdom of Balhae, which governed the Suifen country through its Suibin prefecture. The district was famed for horses, prized beyond its borders and traded to Tang China. Although Balhae fell to the Khitans in 926, the remains of its fortified settlements continued to mark the valley long after the kingdom itself had disappeared.
