Li Deyu
In 820, Emperor Xianzong died and was succeeded by his son Emperor Muzong. Emperor Muzong made Li Deyu, in addition to his imperial censor position, an imperial scholar (翰林學士, "Hanlin Xueshi") as well. It was said that because Emperor Muzong had long heard about Li Jifu while he was crown prince, he had respect for Li Deyu. Soon thereafter, Li Deyu was made "Tuntian Yuanwailang" (), a low-level official at the ministry of public works (工部, "Gongbu"), and continued to be imperial scholar. It was said that because Li Deyu saw that at the time, the imperial relatives were becoming influential and making improper requests, he submitted a petition that requested that imperial relatives be required to meet the chancellors at the Office of the Chancellors, rather than at private homes. Li Deyu was then promoted to be "Kaogong Langzhong" (), a supervisory official at the ministry of civil service affairs (吏部, "Libu"), and put in charge of drafting edicts.
