Tuoba Hena
Lady Qi assassinated Yulü in a coup and place his second-oldest brother, Tuoba Heru on the throne in 321.Tuoba Hena led his troops to face him north of the border pass at Gouzhu (句注, northwest of present-day Dai County, Shanxi) but was defeated.Hena then led an attack with the Yuwen tribe against the Helan but failed to meet success, and Yihuai survived the assault.In 337, the Zhao general, Li Mu (李穆), escorted Tuoba Yihuai with 5,000 cavalry to Daning.The tribes once more acclaimed Yihuai as the Prince of Dai, so Hena this time fled to Former Yan in Liaodong, where he was received by the ruling Murong clan.
