李道宗
In summer 635, Tang forces began engaging Tuyuhun forces, and after some minor victories by Li Daozong, Murong Fuyun, apparently following the same strategies he used against Duan, burned the grasses and fled. Most of Li Jing's subordinates believed that it was dangerous to venture further without adequate grazing supplies and advised withdrawal, but Hou opposed the idea, pointing out that this was the opportunity to destroy Tuyuhun. Li Jing agreed, and divided his forces into two branches—with Li Jing himself, Xue Wanjun (薛萬均) and Li Daliang heading northwest, and Hou and Li Daozong heading southwest. Both prongs continued to be successful, although during one battle Xue Wanjun and his brother Xue Wanche (薛萬徹) fell into a Tuyuhun trap and were nearly killed, saved only by the heroics of Qibi Heli (契苾何力). Eventually, Li Jing received news of Murong Fuyun's location and surprised Murong Fuyun, defeating his remaining forces. Murong Fuyun himself managed to flee, but the nobles, led by his son Murong Shun the Prince of Daning—who, as Murong Fuyun's oldest son by his wife, Sui Dynasty's Princess Guanghua, had been resentful at not being made crown prince—killed the Prince of Tainzhu and surrendered. Murong Fuyun, in flight, was killed by his subordinates. Emperor Taizong created Murong Shun the dual titles of Prince of Xiping and Zhugulüwugandou Khan (or Gandou Khan in short), to succeed Murong Fuyun.
