《元和郡县图志》卷八“河南道四”许州鄢陵县条下云:“鄢陵故城,县西北十五里。太丘城,县西南二十里,陈寔尝为此县长。”~①此说有误。《后汉书·陈寔传》云:“陈寔字仲弓,颍川许人也……复再迁除太丘长……以沛相赋敛违法,乃解印绶去,吏人追思之。”~②可知陈寔担任过太丘长,后因为沛国相违法,陈寔辞官而去,这说明太丘与沛之间有一定的联系。又据《续汉书·郡国志二》沛国条下,有21城,太丘是其中之一。不难看出太丘是沛国下辖的一个县。且《续汉书·郡国志二》颍川条下也没有关于太丘城的记载。又《水经注》睢水条下有“(睢水)又东过睢阳县南……睢水又东迳谷熟县故城 ”Yuanhe County map“ Volume eight ”Henan Road Four “ Xuzhou Yanling County article cloud: ”Yanling Gucheng, county northwest fifteen .Taqiucheng, county twenty miles southwest, Chen Wei taste To this county magistrate. “~ ① This is wrong. ”Later Han Chen 寔 Biography“ cloud: ”Chen 寔 words secondary bow, Yingchuan Xu also ... ... and then remove too Qiuchang ... ...

According to “continued Han Guo Guoshi two” Peiguo Article, 21 City, too Qiu is one of them. It is not difficult to see too Qiu is a county under the jurisdiction of Pei. And “Continued Han Guojunzhi two” under the Yingchuan article is not about too Qiucheng records.
