《水经注·卷二十三》
向了许多道家，有人说他生于颖川，有人说他生于蒙。初时修建此城时，就已声了这座坟墓了，据古人相传，说是王氏墓。
博问道家，或言颖川，或言产蒙，初建此城，则有斯丘，传承先民，曰王氏墓。
When we asked many Taoists, some said he was born in Yingchuan, and some said he was born in Meng. At the beginning of the construction of the city, the tomb has been built, according to ancient tradition, they said it was Wang's tomb.
