《新唐书·列传·卷五十》
后来，王君耯在青海西大破吐蕃兵。张说估计王君耯会败，于是将辒州的斗羊献给皇帝，上表说： 假如羊能说话，它必定会说 ：斗而不止，当即就有斗死的。 
后君■破吐蕃于青海西，说策其且败，因上巂州斗羊于帝，以申讽谕，曰： 使羊能言，必将曰 斗而不解，立有死者 。
Later, Wang Junkuai defeated the Tubo army in western Qinghai. Zhang said estimated that Wang Junkuai would be defeated, so he dedicated the fighting ram from Youzhou to the emperor and said in a memorial: If the ram could speak, it would definitely say: If the fighting continues, there will be deaths immediately.
