《新唐书·列传·卷一百四十一》
何力说： 吐蕃地处西方边陲，臣担心王师到达，他们都已逃窜埋伏，我们征讨追捕无所得。到春天，他们又会侵犯吐谷浑。
何力曰： 吐蕃介在西极，臣恐师到，兽窜山伏，捕讨无所得，至春复侵吐谷浑。
He Li said: Tubo is located on the western border. I am worried that when the king's division arrives, they will have already fled in ambush, and we will gain nothing from the expedition and arrest. In the spring, they will invade Tubo again.
