Notching the Boat to Find the Sword
楚人舟中坠剑，在船舷刻记号，靠岸后从刻处下水找剑。不知船已行。讽刺用静止方法处理变化问题。
A man drops his sword from a boat, notches the gunwale, and later searches by the notch—ignoring the boat has moved. Against fixed methods in changing conditions.
环境变了，记号也会失效；更新你的参照系。
When context moves, marks fail—update your frame.
After the moral, ask one question: if a similar choice showed up today, where does the story snag? Name that tension first—then take your own step. You need not copy the ancients, only borrow their clarity.
