侯君集
Murong Shun's reign was short—plagued by the people's lack of respect for him, because he had long served as a hostage to Sui. In winter 635, he was assassinated. His son Murong Nuohebo the Prince of Yan succeeded him, and there was much infighting. Emperor Taizong sent Hou Junji to Tuyuhun with an army to pacify the Tuyuhun people so that they would submit to Murong Nuohebo's rule. In 636, Murong Nuohebo petitioned to formally submit to Tang, and Emperor Taizong created him the dual titles of Prince of Heyuan and Wudiyebaledou Khan (or Ledou Khan in short).
