Spear and Shield Contradicting Each Other （成语 自相矛盾 英文）


There was a man who was a seller of spears and shields. To advertise the firmness of his shields, he cried,"Look, nothing can penetrate my shields." A moment later, to advertise the sharpness of his spears, he cried,"Look, there's nothing they will not penetrate."

"How about using your own spear to try on your own shield?" someone asked.

The man could not make a reply.
