《水经注·卷二十一》
此城是贾复南下攻哪时所筑。民间音讹，称为寡妇城，水称寡妇水。这条水有时会干涸，因此有枯渠之称。
径贾复城北，复南，击郾所筑也。俗语讹谬，谓之寡妇城，水曰寡妇水。此渎水有穷通，故有枯渠之称焉。
This city was built when Jia Fu attacked the south. The folk pronunciation has been distorted, and it is called the Widow's City, and the water is called the Widow's Water. This water sometimes dries up, hence the name Dry Canal.
