《史记·三十世家·五宗世家》
天子派遣大行令张骞核实王后的所作所为并审讯刘勃，请求逮捕与刘勃相奸淫的诸人作为佐证，刘勃又设法把他们藏匿起来。
天子遣大行骞验王后及问王勃，请逮勃所与奸诸证左，王又匿之。
The emperor sent Da Xingling Zhang Qian to verify what the queen had done and to interrogate Liu Bo. He asked for the arrest of those who had fornicated with Liu Bo as evidence, and Liu Bo hid them away.
