Западная Цинь
In 426, with Western Qin's prince Qifu Chipan attacking Northern Liang, Northern Liang's prince Juqu Mengxun sent messengers to persuade Helian Chang to attack the Western Qin capital Fuhan (枹罕, in modern Linxia Hui Autonomous Prefecture, Gansu). Helian Chang, in response, sent his general Hulu Gu (呼盧古) to attack Wanchuan (苑川, in modern Baiyin, Gansu) and Wei Fa (韋伐) to attack Nan'an (南安, in modern Dingxi, Gansu), and while Western Qin was able to hold Wanchuan, Nan'an fell, at great loss. In winter 426, Xia forces commanded by Hulu and Wei attack Fuhan, forcing Qifu Gangui to move the capital to Dinglian (定連, also in Linxia), and Hulu and Wei then captured another important Western Qin city, Xiping (西平, in modern Xining, Qinghai), and while they then withdrew, Western Qin had been dealt a major blow.
