《明史·列传·卷一百二十九》
国家可得田数万顷，每年增加千万石谷，京城的人民从此富足，不用担心水旱灾害，即使不幸运河漕运被阻塞，也可以改道于南，取粮于北。 
所部六府，可得田数万顷，岁益谷千万石，畿民从此饶给，无旱潦之患。即不幸漕河有梗，亦可改折于南，取籴于北。 
The state can get tens of thousands of hectares of land and add tens of millions of stones of rice every year. The people of the capital will then be rich and need not worry about droughts and floods. Even if the Hebei Canal is blocked, the route can be changed to the south and grain can be obtained from the north.
