《新唐书·列传·卷四十一》
如今孟春时练兵，以阴政触犯阳气，危害了生物的生机。臣担心涝水将会冲毁东西，霜雪会打坏庄稼，以致夏麦不熟。
今孟春讲武，以阴政犯阳气，害发生之德，臣恐水潦败物，霜雪损稼，夏麦不登。
Now the training of troops in early spring violates the yang energy with the yin policy, endangering the vitality of living beings. I am worried that the flood will destroy things in the east and west, and the frost and snow will damage the crops, so that the summer wheat will not ripen.
