《明史·列传·卷一百一十一》
近来改凿新渠，远远地避开黄河，舍低就高，地形平坦，各座闸门不必繁琐地开启与关闭，船一天可以航行一百多里，民夫、差役基本上无事可做。
属者改凿新渠，远避黄流，舍卑就高，地形平衍，诸闸不烦起闭，舟行日可百余里，夫役漫无事事。
Recently, the new canal was excavated, avoiding the Yellow River from a great distance, abandoning the low and taking the high, and the terrain was flat. The gates did not need to be opened and closed frequently. Ships could sail more than a hundred li a day, and the civilian laborers and servants basically had nothing to do.
