《旧五代史·后唐·庄宗纪二》
庄宗因为契丹王阿保机和武皇多次在云中结盟，结为兄弟，有急难时互相救助，现在却容纳叛将，违背盟约侵犯边塞，便送信责备他。
帝以契丹主安巴坚与武皇屡盟于云中，既又约为兄弟，急难相救，至是容纳叛将，违盟犯塞，乃驰书以让之。
Emperor Zhuangzong, because the Qidan Emperor Yelu Abaoji and Emperor Wumiao had allied with each other many times in the Yunchong region and become sworn brothers, had agreed to aid each other in times of difficulty, but now he had taken in a rebel general and violated the treaty by invading the border, so he sent a letter to him to reproach him.
