Поздняя Цинь
One thing that Murong Chao immediately opened negotiations with Later Qin on was to request Later Qin to deliver his mother and wife to him. Murong Chao accepted the Later Qin emperor Yao Xing's terms—submit as a vassal, and also to deliver Former Qin imperial musicians who had become Southern Yan court musicians to Later Qin. In 407, Yao Xing delivered Lady Duan and Lady Huyan to Southern Yan. Murong Chao created Lady Huyan empress in 408.
