Tian Chengsi
In 775, Tian Chengsi, who governed nearby Weibo Circuit (魏博, headquartered in modern Handan, Hebei) and who had long had designs on Zhaoyi, induced Xue E's subordinate Pei Zhiqing (裴志清) to rise against him. Xue E fled from Zhaoyi's headquarters at Xiang Prefecture (相州) to Ming Prefecture (洺州, in modern Handan), whose prefect Xue Jian (薛堅) was a relative, and made a petition to Emperor Daizong to allow him to report to the capital Chang'an. Emperor Daizong agreed, and when Xue E arrived at Chang'an, he wore mourning clothes and begged punishment from Emperor Daizong. Emperor Daizong did not punish him, however. There was no further historical records about Xue E's activities afterwards, and it is not known when he died.
