Battle of Fei River
Not much was known about Lady Helan or her son for a number of years. In 384, after Former Qin had begun to collapse in light of its defeat at the Battle of Fei River, Liu Kuren tried to aid the Former Qin prince Fu Pi, but was assassinated by his own general Muyu Chang (慕輿常). His son Liu Xian (劉顯) later tried to kill Tuoba Gui, but Lady Helan heard the news and allowed her son to flee. Later, both were again at Helan tribe, when similarly her brother Helan Rangan (賀蘭染干) tried to kill Tuoba Gui, but stopped after she interceded.
