《明史·列传·卷一百九十九》
此时，各土司都桀骜不驯，难于节制。乌撒、东川、乌蒙、镇雄各军民府的地界交错复杂地分布于川、滇、黔、楚之间，分别统辖，权力不统一，往往一越出范围就成为边疆的祸患。
时诸土司皆桀骜难制，乌撒、东川、乌蒙、镇雄诸府地界，复相错于川、滇、黔、楚之间，统辖既分，事权不一，往往轶出为诸边害。
At this time, all the native chieftains were extremely arrogant and difficult to control. Wusa, Dongchuan, Wumeng, and Zhenxiong military and civilian prefectures' borders were all in a complex and tangled distribution position among Sichuan, Yunnan, Guizhou, and Huguang, and they were governed separately. They lacked unified authority, and they often became sources of trouble along the borders as soon as they overstepped their bounds.
