《旧唐书·列传·卷三十九》
臣担心水涝败坏庄稼，霜雪损坏庄稼，夏麦不能很好生长，没有粮食收入，伏望陛下能顺时令，到冬月讲武习兵，来顺应天道。 
臣恐水潦败物，霜雪损稼，夏麦不登，无所收入也。伏望天恩不违时令，至孟冬教习，以顺天道。 
I am concerned that floods may damage crops, frost and snow may damage crops, and summer wheat will not grow well. Without a grain harvest, I implore Your Majesty to follow the seasons and observe the winter order for military exercises and training.
