郭子仪也下了马，上前拉着药葛罗的手，责备他说： 你们回纥对我们唐朝是有大功劳的，唐朝报答你们也不薄，为何背信弃义，深入我内地，侵犯进逼京畿郊县，放弃前功，新结怨仇，违背恩德而帮助叛臣，这是多么愚蠢啊！
子仪亦下马，前执药葛罗手，让之曰： 汝回纥有大功于唐，唐之报汝亦不薄，奈何负约，深入吾地，侵逼畿县，弃前功，结怨仇，背恩德而助叛臣，何其愚也！
Guo Ziyi also dismounted his house, stepped forward and took Yaogeluo’s hand, and chided him, saying, “Your Huihe people have rendered great service to our Tang Dynasty, and the Tang Dynasty has also amply rewarded you. Why have you betrayed the code of loyalty and invaded deep into our interior, encroaching upon the capital region, abandoning your past contributions and creating new grievances, turning your back on your benefactor to aid a rebel subject? How stupid can you be!”
