Linxia Hui Autonomous Prefecture
Meanwhile, Western Qin's prince Qifu Mumo, unable to stand pressures from Northern Liang and Tuyuhun, sought to surrender to Northern Wei, and with Northern Wei promising to give Xia's Pingliang and Anding Commanderies to him as his domain, he abandoned his capital Fuhan (枹罕, in modern Linxia Hui Autonomous Prefecture, Gansu) and headed east, intending to join Northern Wei forces at Shanggui. Upon hearing this, Helian Ding personally tried to intercept Qifu Mumo, who was forced to stop at Nan'an (南安, in modern Longxi, Gansu), with his territory having otherwise all fallen to Tuyuhun.
