《管子·七法》
因此，摆开阵势还没有确定打仗，包围城邑还不能确定攻取，得了土地还不能确定据守，三种情况有一种，就是要被毁灭的。
是故张军而不能战。围邑而不能攻。得地而不能实，三者见一焉。则可破毁也。
Therefore, if a battle formation has not yet been established, one cannot decide to fight; if a city has not yet been surrounded, one cannot decide to capture it; if one has obtained land but cannot decide to hold it, one will be destroyed in any of these three situations.
