杨朝晟便与诸将密谋，清晨率领甲士出来，召集叛乱的兵士告诉他们说： 你们先前的请求未获皇上恩准，张尚书来了，昨日已进入州城。
朝晟乃与诸将密谋，晨率甲兵而出，召叛卒告曰： 前请者不获，张尚书来，昨日已入邠州。
Yang Chaosheng conspired with the generals. In the early morning, he led the soldiers out and summoned the rebellious soldiers. He told them that "Your previous request was not approved by the emperor. Zhang Shangshu has come and entered the prefectural city yesterday."
