Gao Jiong
Over the years, the relationship between Emperor Wen and Empress Dugu was still largely loving. However, on one occasion, when Emperor Wen happened to see the beautiful granddaughter of Yuchi Jiong, who had been forced into slave labor after her grandfather's death, he had sexual relations with her. When Empress Dugu found out, she had Lady Yuchi killed. In anger, Emperor Wen rode away from the palace on a horse and refused to return. Gao Jiong and Yang Su had to track him down and urge him to return to the palace, with Gao stating, "Your Imperial Majesty, how can you abandon the empire on account of a woman?" When Emperor Wen did return to the palace after midnight, Empress Dugu was still waiting for him, and she wept and begged him for forgiveness. Gao and Yang Su subsequently hosted a banquet for them, and their differences went away.
