《资治通鉴·后梁纪·后梁纪一》
晋兵仍在余吾寨，后梁太祖怀疑晋王李克用是装死，想要召回军队，又怕晋兵尾随追击，于是商议亲自到泽州接应召回的军队，并且召匡国节度使刘知俟俊率兵赶往泽州。
晋兵犹屯余吾寨，帝疑晋王克用诈死，欲召兵还，恐晋人蹑之，乃议自至泽州应接归师，且召匡国节度使刘知俊将兵趣泽州。
The Jin troops were still in Yuwu Camp. The Later Liang Emperor suspected that King Li Keyong of Jin was feigning death, and wanted to recall the troops, but was afraid that the Jin troops would pursue him, so he discussed personally going to Zezhou to meet the recalled troops, and also summoned Liu Zhijun, the Jiedushi of Kuangguo, to lead troops to Zezhou.
