Juqu Mengxun commissioned Suo Yuanxu () to be the governor of Dunhuang. However, Suo quickly lost favor with the people by being rude, dishonest, and cruel. Some people of Dunhuang, under the leadership of Song Cheng () and Zhang Hong (), secretly invited Li Xun back to Dunhuang, and in winter 420 he did so, forcing Suo to flee. Song and Zhang offered Li Xun the titles of General Guanjun () and Governor of Liang Province (), and he changed the era name to signify that Western Liang was still a state. Juqu Mengxun then sent his heir apparent Juqu Zhengde () to attack Dunhuang, and Li Xun defended the city, refusing to engage Juqu Zhengde.
