Li Guangbi
Meanwhile, Tang and Huige forces had also captured Luoyang, forcing An Qingxu to flee to Yecheng, but most of his generals submitted to Tang, leaving him only with control of the region around Yecheng. Shi, in control of Fanyang and surrounding regions, also submitted to Tang, and was made a Tang general. However, Li believed that Shi would eventually rebel again anyway, and persuaded Emperor Suzong to have Shi's associate Wu Cheng'en (烏承恩) assassinate him and take over the region himself. When Shi realized this, he killed Wu and submitted a petition demanding that Emperor Suzong kill Li. Emperor Suzong disavowed any knowledge on his part or Li's and tried to placate Shi, but Shi then rebelled again. In fall 758, Li went to Chang'an to visit Emperor Suzong and was given the additional title of "Shizhong" (侍中) as honorary chancellor. Soon thereafter, he and several other key commanders, including Guo, Lu Jiong (魯炅), Li Huan (李奐), Xu Shuji (許叔冀), Li Siye, Ji Guangchen (季廣琛), Cui Guangyuan (崔光遠), Dong Qin, and Wang Sili (王思禮), rendezvoused at Yecheng to put An Qingxu under siege. Because both Li Guangbi and Guo had great contributions, Emperor Suzong did not make either of them the overall commander of the forces, but commissioned the eunuch Yu Chao'en to serve as the surveyor of the troops. During the siege, Li Guangbi suggested launching an all-out assault on Yecheng's defenses, but Yu opposed, and such an assault was not carried out.
