Murong Fuyun
Around the new year 635, Emperor Taizong sent Li Jing to attack Tuyuhun again. In summer 635, Tang forces began engaging Tuyuhun forces, and after some minor victories by Li Jing's subordinate 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 Junji 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 and Xue Wanjun (薛萬均) and Li Daliang heading northwest, and Hou and Li Daozong heading southwest. Both prongs continued to be successful. 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 Murong Shun, killed the Prince of Tianzhu 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.
