《明史·列传·卷一百三十六》
三岔河离代子河不远，敌人从代子河直接渡河，防守三岔河的士兵不到二万人，能看着敌人渡到一半再阻止吗？
河去代子河不远，兵从代子径渡，守河之卒不满二万，能望其半渡而遏之乎？
Sancha River is not far from Daizi River. If the enemy crosses Daizi River directly, the soldiers defending Sancha River will only be able to muster twenty thousand men. Will they be able to stop the enemy once they have already crossed halfway?
