Juqu Mengxun
In 418, Juqu Mengxun attacked Western Liang again, and Li Xin was preparing to meet him in battle. His official Zhang Tishun () persuaded him against it, however, and instead he stayed in his capital Jiuquan (酒泉, in modern Jiuquan, Gansu), and Juqu Mengxun, not willing to siege the city, withdrew. Later that year, because he had previously sent messengers to Jin, offering to be a vassal, Jin created him the Duke of Jiuquan.
