《新唐书·列传·卷一百一十》
皇帝逃到梁州、洋州去，郑畋在斜谷拜见皇帝，哭着说： 文武官员害了国家，我请求被处死来警告失职的。 
帝出梁、洋，畋上谒斜谷，泣曰： 将相误国，臣请死以惩无状。 
The emperor fled to Liangzhou and Yangzhou, and Zheng Tian went to see him at Xiegu, where he tearfully said, "The civil and military officials have brought ruin on the nation. I beg you to execute me as an example to those who have neglected their duties."
