《水经注·卷十一》
旧城东侧，利用曲折的地势和城墙又筑了一座城，世人称为寡妇城。贾复在北平随从光武帝追击铜马、五蟠二军时筑了此城。
其城东侧，因阿仍墉筑一城，世谓之寡妇城，贾复从光武追铜马、五幡于北平所作也。
To the east of the old city, using the tortuous terrain and the city walls, another city was built, which was called the Widow City. Jia Fu built this city when he followed Emperor Guangwu in Beiping to pursue the Bronze Horse and the Five Pan Armies.
