《魏书·列传·卷六十二》
尔朱荣偷偷在山谷伏军作为奇兵，分督将以上的军官三个人为一处，每处数百名骑兵，命令他们在埋伏的地方扬尘呐喊，以使敌人弄不清有多少人马。
荣潜军山谷为奇兵，分督将已上三人为一处，处有数百骑，令所在扬尘鼓噪，使贼不测多少。
Erzhurong secretly ambushed the troops in the valley, and divided the officers above the military governor into three parts, each with hundreds of cavalry, and ordered them to raise dust and shout in the ambush, so that the enemy could not figure out how many horses there were.
