the Former Qin emperor Fu Deng, to whom Qifu Guoren had nominally submitted as a vassal, created Qifu Gangui the Prince of Jincheng—a title that signified less dominion than his original title of Prince of Henan, because Jincheng Commandery only roughly corresponded to modern Lanzhou—but Qifu Gangui accepted the title. In 390, the khan of Tuyuhun, Murong Shilian (慕容視連), submitted to Western Qin as a vassal, and Qifu Gangui created him the Prince of Bailan. However, after Murong Shilian died later that year and was succeeded by his more ambitious son Murong Shipi (慕容視羆), Murong Shipi rejected that title. In 391, Qifu Gangui's general Yuezhi Jiegui (越質詰歸) rebelled, but after Qifu Gangui personally led an army against him, Yuezhi surrendered—and Qifu Gangui married the daughter of a clansman to Yuezhi, showing Qifu Gangui's tendency to try to personally connect with tribal chiefs to get them to submit to him. However, later 391, the strategy could have said to have backfired as the tribal chief Mo Yigan (沒奕干) initially submitted and sent two sons as hostages to him, seeking his aid in a campaign against another tribal chief, Da Dou (大兜). Qifu Gangui aided him and defeated Da in battle, and then sent Mo's sons back to him, to try to get Mo to be more grateful of him. However, Mo instead turned against Qifu Gangui and aligned himself with the Xiongnu chief Liu Weichen (劉衛辰), and Qifu Gangui, in anger, attacked Mo and, in battle, fired an arrow that struck Mo's eye. During the campaign against Mo, however, Lü Guang the prince of Later Liang took this opportunity to attack Western Qin, forcing Qifu Gangui to withdraw to face him. This incident appeared to start several years of intermittent battles between Western Qin and Later Liang. In 393, Qifu Gangui created his son Qifu Chipan as crown prince. In 394, after the death of the Later Qin emperor Yao Chang, Fu Deng prepared a major offensive against Yao Chang's son and successor Yao Xing, and as part of the preparation he requested aid from Qifu Gangui and created Qifu Gangui the Prince of Henan and bestowed on him the nine bestowments. However, Fu Deng's campaign ended in failure, as his forces were defeated by Yao Xing's, and his brother Fu Guang (苻廣) and son Fu Chong abandoned his bases, forcing him to flee into the mountains. He then married his
