《北史·列传·卷三十七》
尔朱兆率领精锐骑兵冲陷敌阵，出现在高欢军队之后，准备在他的背后发起进攻，尔朱度律妒嫉尔朱兆的骁勇凶悍，害怕他超过自己，所以，按兵不动。
兆率铁骑陷阵，出齐神武后，将乘其背而击之。度律恶兆之骁悍，惧其陵己，勒兵不进。
Erzhu Zhao led an elite cavalry and broke through the enemy lines, appearing behind Gao Huan’s troops and preparing to launch an attack from the rear. Yet Erzhu Dulu, out of jealousy of Erzhu Zhao’s prowess, feared that Erzhu Zhao would outshine him, so he held his troops back and refused to attack.
