In the second year of Houyuan, Emperor Wu fell ill and traveled between the two palaces of Changyang and Wuzhuo. A fortune teller said that there was the spirit of the emperor in the prison of Chang'an, so Emperor Wu sent messengers to make a complete list of the prisoners in the prison of Zhongduguan Shao, and ordered that all of them be killed regardless of the severity of their crimes.
