《明史·列传·卷一百一十一》
徐贞明询问原因，伍袁萃讲： 北方人害怕东南地区的漕运负担加派到西北地区，厌烦的话必然会出现。 
贞明问故。袁萃曰： 北人惧东南漕储派于西北，烦言必起矣。 
Xu Zhengming asked why, and Wu Yuancui said: “The people of the north are afraid that the burden of grain transport from the southeast will be imposed on the northwest, and words of complaint will inevitably appear.”
