 During the rule of Emperor Ling (168-189) of the Eastern Han, Lý Tiến was the first native of Jiaozhi to be the inspector of Jiaozhou.Lý Tiến then petitioned the Han emperor to allow natives of Jiaozhi to be officers and mandarins in the Han court, but the emperor only accepted the ones who were awarded maocai (茂才) or xiaolian (孝廉) titles.Another native of Jiaozhi named Lý Cầm petitioned the throne and eventually the natives were allowed to take higher positions in other regions of the Han empire.
