It is not known when Murong Nuohebo was born. In 635, his grandfather, the Busabo Khan Murong Fuyun, who had been aggravating China's Tang Dynasty for years with border raids, drew a Tang reprisal attack, commanded by the general Li Jing, and was killed in flight. Murong Nuohebo's father Murong Shun surrendered and was created the Gandou Khan to succeed Murong Fuyun, but as Murong Shun had spent years in China during Sui Dynasty and his mother was Sui's Princess Guanghua, he was considered too sinicized and not supported by the people. Late in 635, he was assassinated. Murong Nuohebo, who was said to be young (although his age by that point is unknown), and who carried the title of Prince of Yan, became khan. Emperor Taizong of Tang sent the general Hou Junji with Tang troops to help Murong Nuohebo pacify the Tuyuhun people.
