Dìngbiān

Dingbian lay in the mountain country south of Dali, at a gateway toward the valleys of southwestern Yunnan. In 1388 a force from Luchuan advanced into the district. The Ming commander Mu Ying marched to its relief with cavalry and defeated the invaders at Dingbian. The county remained a place of garrisons and cultivation under the Ming. In 1729 the Qing abolished it, placing its territory under Menghua and establishing a patrol office at Nanjian.
