Feng Ba
Later that year, Yujiulü Hulü, who was about to in turn marry one of his daughters to Feng Ba, was overthrown by his nephew Yujiulü Buluzhen (郁久閭步鹿真), and the coup leaders sent him and his daughter to Northern Yan. Feng Ba treated him as an honored guest and, as originally planned, took his daughter, Zhaoyi (昭仪), as a concubine. Yujiulü Hulü requested that Feng Ba send an army to escort him home, and Feng Ba, with some reluctance, sent his general Wan Ling (萬陵) to escort Yujiulü Hulü, but Wan killed Yujiulü Hulü on the way and returned. Instead, Feng Ba entered into an alliance with the new khan Yujiulü Datan, who had in turn overthrown Yujiulü Buluzhen.
