《北史·列传·卷三十八》
奋勇杀敌，死了奖赏却一再拖延；临阵逃脱，身体得以保全而不受惩罚，这就是士卒所以望风逃窜、不肯奋力进击的原因啊！
赏罚，陛下之所易，尚不能全而行之；攻敌，士之所难，欲其必死，宁可得也？ 
Fighting bravely to kill the enemy but the rewards were repeatedly delayed; escaping from battle and the body was kept intact and unpunished. These were the reasons why the soldiers fled when the wind blew and were not willing to fight hard.
