Gao Jiong
By 599, both Emperor Wen and Empress Dugu were considering replacing Yang Yong with Yang Guang. When Empress Dugu tried to see if she could have support in this proposition from Gao Jiong, Gao, whose son Gao Biaoren () married Yang Yong's daughter, stated his opposition, and this, coupled with Gao Jiong's own favor for a concubine after his wife's death, eventually caused Emperor Wen and Empress Dugu to deposed Gao Jiong from his influential posts in fall 599.
