Xue Rengui
This television series also portrays Xue Rengui travelling from Chang'an with only his friend and bodyguard Hongpei to the Khitan-held Yingzhou in order meet his old war protege the Khitan Khan Li Jinzhong to personally warn him about general Li Wen's desire to destroy the Khitans in the year 695. But this is apparently a symbolic gesture made by the show's producers, since General Xue Rengui died in 683, to indicate his good and friendly nature and his disdain for political matters.
