《水经注·卷三十一》
有一座高峰叫悬钩峰，在平原上许多丘陵中，显得分外秀丽突出。山下有石门，两边山崖层沓，极其险峻，岩高都有数百仍。
峰曰悬钩，处平原众阜之中，为诸岭之秀，山下有石门，夹鄣层峻，岩高皆百许仞。
There is a tall peak called Xuan Goufeng. It is particularly beautiful and prominent among the many hills on the plain. There is a stone gate under the mountain. The cliffs on both sides are steep and extremely rugged. The rocks are hundreds of fens high.
