Making His Mark
Once upon a time a man from the state of chu was orossing a river by boat. But carelessly his sword fell into the water. Immediately he made a mork on the boat. He said, “This is where my sword fell off.”
When the boat stopped moving, he went into the water to look for his sword at the place where he had worked the boat. Of couse he couldn’t find it. He didn’t know the boat had moved but the sword had not.
