《资治通鉴·周纪·周纪三》
崤山以东的军队要身披铠甲才肯作战，而秦国军队则脱下铠甲赤臂就可驱敌，左手提着人头，右臂挟着战俘。
山东之士被甲蒙胄而会战，秦人捐甲徒裼以趋敌，左挈人头，右挟生虏。
Soldiers to the east of the Xiaoshan mountains need to wear armor to fight while the Qin army can win even without armor. The Qin soldiers hold heads of the enemy in their left hands and captured soldiers in their right hands.
