《旧唐书·本纪·卷十七》
还听说郑注原来在凤翔招募了不少士兵，现在一律处死，我耽心会激起事变，应该从宽处理免于追究，也好稳定人心。 文宗说 ：你讲得不错啊！ 
又闻郑注在凤翔招致兵募不少，今皆被刑戮，臣恐乘此生事，切宜原赦以安之。 
I also heard that Zheng Zhu originally had recruited many soldiers in Fengxiang. Now, all of them have been put to death. I'm afraid that this will stir up trouble. We should handle it leniently and refrain from investigating, so the people's hearts can be settled. Emperor Wenzong said: What you said made sense!
