《北史·列传·卷三十五》
如果统率军队有方，道德清纯著名，威严足可以临阵杀敌，信誉完全能怀柔边境的人民，抚慰将士，能得到他们的信赖和喜欢。不谋图私利，一心为公尽力的，就加封给爵位，使他长久地安心在这个任上。
若能驾御有方，清高独著，威足临戎，信能怀远，抚循将士，得其忻心，不营私润，专修公利者，则就加爵赏，使久于其任，以时褒赉，厉其忠款。
If the commander of the army is well-organized, virtuous, famous, majestic enough to kill the enemy in battle, and trustworthy enough to appease the people on the border and comfort the soldiers, and they can gain their trust and love. Those who do not seek personal gain and devote themselves to the public good will be given titles and titles, so that they can settle down in this position for a long time.
