《水经注·卷十九》
太子弄巫术害人一案被揭发后，砍开杜门向东出逃，史良娣被杀，葬开苑北，宣帝称为庚园；又因有戏子千人在思后的园庙里作乐，所以又叫千乡。
太子巫蛊事发，斫杜门东出。史良娣死，葬于苑北，宣帝以为戾园，以倡优千人乐思后园庙，故亦曰千乡。
When the witchcraft incident carried out by the crown prince came to light, he escaped eastward after cutting open Dumen Gate. Concubine Shi was killed and buried north of Kaiyuan, which was named Gengyuan by Emperor Xuan. Also, there were a thousand performers playing music in the garden temple of his posthumous shrine, and that was why it was also called Qianxiang.
