《资治通鉴·唐纪·唐纪十三》
如今一朝陡生变化，有改悔之意，我深深为朝廷的声誉受损而惋惜；这样一来得到的很少，而失去的却很多，也会产生隔阂，必然会遭致边境不安宁。
今一朝生进退之意，有改悔之心，臣为国家惜兹声听；所顾甚少，所失殊多，嫌隙既生，必构边患。
Now that there is a sudden change, and there is a change of heart, I deeply regret that the reputation of the court has been damaged. In this way, one gets very little, but loses a lot, and will also create a gap, which will inevitably lead to unrest on the border.
