Abstract: Opening uo of Miao Territory of Yongzheng Reign in southeast Guizhou was carried out in two areas both by suppression and pacification measures, as represented by the policies of two officials, Fang Xian and Zhang Guangsi. Though pacification measures proved to be effective, efforts to open this territory usually ended with armed force. Suppression and pacification measures were employed simultaneously. The reasons why opening Miao Territory ultimately ended in suppression included, ignorance of the distinctiveness of local culture and tradition by officials standing of suppression, a lack of law for controlling the army, soliders taking credit for the success of others, a lack lf suitable policy for control, and  the cycle of one mistake leading to another.
