A man of the state of Chu had a spear and a shield for sale. He was loud in praises of his shield.
"My shield is so strong that nothing can pierce it through."
He also sang praises of his spear.
"My spear is so strong that it can pierce through anything."
"What would happen," he was asked, "if your spear is used to pierce your shield?"
It is impossible for an impenetrable shield to coexist with a spear that finds nothing impenetrable.
參考答案:有意思~~"以子之矛 攻子之盾"的英文版~~
原文出自《韩非子·难一》：“楚人有鬻楯（通“盾”）与 矛者，誉之曰：‘吾楯之坚，莫能陷也。’又誉其矛曰：‘吾矛之利，於物无不陷也。’或曰：‘以子之矛，陷子之楯，何如？’其人弗能应也。”
短文翻译:
有个卖盾和矛的楚国人，夸他的盾说：“我的盾坚固得没有一个东西刺得破啊。”又夸他的矛说：“我的矛锋利得没有一个东西刺不破啊。”有人说：“用您的矛来刺您的盾，会怎么样？”那个人可就回答不出来啦。刺不破的盾和什么东西都刺得破的矛不可能同时存在。
