Zhao Mo
Zhao's name was recorded as Zhao Hu () in the "Records of the Grand Historian" by Sima Qian. The name of Zhao Mo did not arise until the discovery of two jade seals belonging to the emperor that bore the name of Zhao Mo but not Zhao Hu. "Zhao Hu" may have been an error made by Sima Qian when he was writing his "Records". There is also a theory that Zhao Mo and Zhao Hu were two separate rulers, and that Zhao Mo's reign was excluded from historical records because of its brief duration.
