周武帝
Gao Jiong was himself skilled in history and rhetoric while young. When he was 16, Yuwen Xian the Prince of Qi made Gao Jiong a member of his staff. He inherited the title of Count of Wuyang that had been created for his father. He apparently served under Yuwen Xian when Yuwen Xian was a major general in the campaign of his brother Emperor Wu of Northern Zhou in destroying rival Northern Qi, (Eastern Wei's successor state) and was promoted to a mid-level post in the imperial government.
