《明史·列传·卷九十二》
皇帝发怒说： 过去下令蓟镇练兵，现在一个兵卒也不练，遇到防秋就调他镇之兵，兵部详细讨论这件事，然后报告我。 
帝怒曰： 曩令蓟镇练兵，今一卒不练，遇防秋辄调他镇兵，兵部详议以闻。 
The emperor was furious and said: "I previously ordered the Jizhou garrison to train soldiers, but now they have not trained a single soldier. When the time comes to defend in autumn, they will have to transfer soldiers from other garrisons. The Ministry of War should discuss this matter in detail and then report to me."
