《水经注·卷二十一》
这里本来是汝南郡的治所。从前，费长房当市吏，看见王壶公把壶挂在郡里的市场上，费长房就跟着他，因而从远处和他一同进入壶中，从此他就隐遁修仙，脱胎换骨，身怀灵气，但未学成就返回人间，虽然能遣使鬼神，但最后还是死了。
本妆南郡治，昔费长房为市吏，见王壶公，悬壶郡市，长房从之，因而自远，同入此壶，隐沦仙路，骨谢怀灵，无会而返。虽能役使鬼神，而终同物化。
Here was originally the governing office of Runan County. In the past, Fei Changfang served as a municipal official, saw Wang Hougong hang a pot in the market of the county, Fei Changfang followed him, and thus entered the pot with him from afar. From then on, he became a recluse and cultivated immortality, transformed his body, possessed spiritual energy, but returned to the mortal world before completing his studies. Although he could send out ghosts and gods, he still died in the end.
