In spring 384, however, Murong Chui did start a rebellion near Luoyang, and after he claimed the title of Prince of Yan, thus establishing Later Yan, he created Murong De his old title of Prince of Fanyang. When the news reached Zhangye, the commandery governor Fu Chang (苻昌) arrested and executed Murong Na and all of Murong De's sons (and presumably their mother(s)). Consort Gongsun was spared because of her old age, while Murong Na's wife Lady Duan, who was then pregnant, was imprisoned to await for execution after she gave birth. Consort Gongsun and Lady Duan, however, were rescued by Murong De's former subordinate Huyan Ping (呼延平), who escorted them to the Qiang tribes.
