《后汉书·列传·西羌传》
当时羌人已经归顺好长时间了，再没有武器镗甲，有的人拿了竹竿木棍代替戈矛，有的人背着木板几案当作盾牌，有的人手拿铜镜象征武器，郡县胆小害怕不能制服。
时羌归附既久，无复器甲，或持竹竿木枝以代戈矛，或负板案以为楯，或执铜镜以象兵，郡县畏懦不能制。
At that time, the Qiang had surrendered for a long time, they no longer had weapons and armor, some of them took bamboo poles and sticks instead of halberds and spears, some of them carried wooden boards and desks as shields, some of them held copper mirrors as weapons, the counties and towns were timid and fearful and couldn't defeat them.
