《后汉书·列传·皇甫嵩朱俊列传》
快救，城就可以保全；不救，城就会破灭。保全或破灭的形势就在这时，皇甫嵩说： 不是这样。
速救则城全，不救则城灭，全、灭之势，在于此也。 
"If you go quickly to save it, the city can be preserved; if you do not go to save it, the city will be destroyed." The choices of preserving it or allowing it to be destroyed are present in this moment, but Huangfu Song said, "It is not so."
