However, Liu Bobo escaped and fled to the Xuegan (薛干) tribe, whose chief, Tai Xifu (太悉伏), refused to turn him over despite Northern Wei's demands. Instead, Tai delivered Liu Bobo to the Xianbei tribal chief Mo Yigan (沒奕干) the Duke of Gaoping, a Later Qin vassal, and Mo Yigan not only gave Liu Bobo refuge but also married one of his daughters to Liu Bobo. Liu Bobo, from that point on, became highly dependent on his father-in-law. (Meanwhile, in 393, Tuoba Gui, because of Tai Xifu's refusal to deliver Liu Bobo to him, attacked Tai and slaughtered his people, although Tai himself escaped and fled to Later Qin.) Little is known about Liu Bobo's life during the following years. In 402, Tuoba Gui's brother Tuoba Zun (拓拔遵) the Prince of Changshan attacked Mo's homebase of Gaoping (高平, in modern Guyuan, Ningxia), and Mo was forced to flee to Later Qin, abandoning his own people, who were scattered about, although later Later Qin recaptured Gaoping and gave that city back to Mo.
