His son Qifu Chipan (Prince Wenzhao) defeated Qifu Gongfu and succeeded him as prince.

However, after Later Qin was weakened by defeats at the hands of its rebel general Liu Bobo's Xia state, Qifu Gangui redeclared independence in 409, but ruled only three more years before he was killed by Qifu Gongfu in a coup. He subsequently expanded the state's power and influence, but only to an extent, and in 400 after military losses to Later Qin, his state was annexed by Later Qin and he himself became a Later Qin general. He was a brother of the founding prince, Qifu Guoren (Prince Xuanlie), who became prince after Qifu Guoren's death in 388 because Qifu Guoren's son Qifu Gongfu (乞伏公府) was considered too young for leadership. Qifu Gangui or Qifu Qiangui ( Chinese: 乞伏乾歸 died 412), formally Prince Wuyuan of Qin (秦武元王), was a prince of the Xianbei-led Chinese Western Qin dynasty.
