《三国志·魏书·刘司马梁张温贾传》
我们这个郡和京城边境相连接，洛阳的东面有成皋县，北面靠近黄河，天下那些发动义兵讨伐董卓的人如果无法前进，就一定会停留在这里。
郡与京都境壤相接，洛东有成皋，北界大河，天下兴义兵者若未得进，其势必停於此。
Our prefecture borders the capital. There is Chenggao County to the east of Luoyang, and the Yellow River to the north. The righteous troops who are going to fight against Dong Zhuo will stop here if they can't move forward.
