Li Hao
However, Duan Ye's official Suo Si (), a friend of Li Hao's, warned Duan Ye of Li Hao's ambitions and advised Duan Ye not to allow Li Hao to remain in control of Dunhuang. Duan Ye therefore sent Suo Si to take over Li Hao's post. Li Hao, in fear, initially was going to receive Suo and turn over authorities to him. At the urging of Song and Zhang Miao (), however, Li Hao first sent messengers to flatter Suo, and instead made a surprise against Suo, defeating him and forcing him to flee back to the Northern Liang capital Zhangye (張掖, in modern Zhangye, Gansu). Li Hao, angry at what he saw as Suo's betrayal, then sent messengers to Duan Ye demanding that he execute Suo. Juqu Nancheng, who also disliked Suo, advised Duan Ye to execute Suo to pacify Li, and Duan Ye did so.
