Murong Fuyun
For reasons lost to history, there was a major disturbance in Tuyuhun in 597, and Murong Shifu was assassinated. The people supported Murong Fuyun as khan. He sent emissaries to Sui to explain the situation and to ask for permission to, pursuant to Tuyuhun customs, marry Princess Guanghua as well. Emperor Wen agreed. (He and Princess Guanghua thereafter had at least one son, Murong Shun.)
