While waiting for the rabbit, there was a farmer in the state of Song. There is a stump in his field. One day, when he went to the farm, he happened to meet a rabbit who ran into the stake and died. So he put down his farm tools and guarded the stump every day, hoping to get the rabbit again. The rabbit didn't get it, but it became a joke of Song State.

Paradoxically, a man sells both spears and shields. When selling spears, he said that his spear was extremely sharp and could pierce anything. When selling shields, he said that his shields were so strong that nothing could penetrate them. Someone asked him how to stab your shield with your spear. He was speechless.
