There was a man in Chu who sold both spears and shields. First he boasted about his shield and said, "My shield is so strong that no matter what spear you use, it can't be broken!" " "Then, he boasted about his spear and said," My spear is so sharp that no matter what shield I use, I can't help it! "Someone asked him," What would happen if you stabbed your shield with your spear? " The man was speechless when asked. A shield that cannot be pierced by any spear and a spear that can be pierced by any shield cannot appear together at the same time.
