Dàníng

Daning is placed in the northern frontier country near Pingquan and the upper Daling River basin. Valleys and uplands connected the agricultural districts of north China with lands farther north. The historical city of Daning was an important administrative and military centre in this broader region.

In 1387 the Ming established the Daning military command at the city, with responsibility for frontier defence. The command was renamed the Beiping regional military commission the following year. After the Jingnan campaign, its headquarters moved to Baoding in 1403 and the old Daning city was abandoned.
