《淮南子·兵略训》
现在有了良箭，再涂饰银锡，但即使是薄绢做成的车帷，腐叶烂草做成的盾牌，这涂饰银锡的衣箭还是不能自动穿透它。
夫括淇卫箘簵，载以银锡、虽有薄缟之赡，腐荷之矰，然犹不能独射也。
Now we have a good arrow and apply tin on it, but even if it is a car curtain made of thin silk or a shield made of rotten leaves and grass, the cloth arrow coated with tin still cannot automatically penetrate it.
