《明史·列传·卷一百三十六》
在这之前，甘肃发生兵变，逃跑的士兵害怕被捕杀死，往往逃至山谷中当强盗，强盗的势力更加嚣张了。
先是，甘肃兵变，其溃卒畏捕诛，往往亡命山谷间，为群盗，贼势益张。
Before this, a rebellion had occurred in Gansu, and the soldiers who escaped were afraid of being caught and killed, so they often fled to the valleys and became robbers, and the influence of the robbers became even more arrogant.
