李勉
By late 783, Li Xilie was putting Bian Prefecture under siege. Li Mian held the city against the siege for more than a month, but with no aid forces arriving, he abandoned Bian Prefecture and took over 10,000 people to flee to Xuanwu's capital Song Prefecture. Li Mian submitted a petition to Emperor Dezong — who was at Fengtian (奉天, in modern Xianyang, Shaanxi) at the time due to rebellion by Zhu Ci, who had seized Chang'an and declared himself the emperor of a new state of Qin — requesting punishment. Emperor Dezong responded, ""I" was unable to defend the imperial ancestral temples. Li Mian needs not be insecure." Li Mian subsequently transferred his troops to Liu Qia. By fall 784, with Li Mian repeatedly requesting punishment, Emperor Dezong removed him from the overall command of the three circuits and the military governorship of Yongping, but recalled him to Chang'an (which had been recaptured by that point) to serve as chancellor as well as acting "Situ" (司徒, one of the Three Excellencies). When Li Mian arrived at Chang'an, many officials commented, "Li Mian lost Daliang [(大梁, another name for Bian Prefecture)] and should not remain as chancellor." Emperor Dezong's trusted senior advisor Li Mi pointed out that while Li Mian was not a capable general, he was a capable governor that the people loved and respected, and that he, by transferring the command to Liu, contributed to Liu's subsequent victory. Emperor Dezong agreed with Li Mi and allowed Li Mian to exercise his authority as chancellor.
