《隋书·列传·卷二十五》
这是因为决定权在他一人手里，所以他能功成名就。现在我们却人各一心，怎能赴敌？ 
仲文惧忻生变，因谓之曰： 丞相宽仁大度，明识有馀，苟能竭诚，必心无贰。
This was because decision-making authority was in the hands of one person, therefore he was able to achieve merits and make a name for himself. Now, our hearts are all set on different things, how can we face the enemy?
