《宋史·列传·卷一百六十一》
杨巨源对安丙说： 吴曦死了，贼胆已破，关外四州是蜀的要害，应该乘势收复。 李好义也这么说。
巨源谓丙曰： 曦死，贼胆以破，关外四州为蜀要害，盍乘势复取。 好义亦以为言。
Yang Juyuan told An Bing, "With Wu Xi dead, the enemy's courage has been destroyed. The four states outside of the pass are important to Shu, so we should seize the opportunity to recover them." Li Haoyi agreed with him.
