Pei Du
In 789, during the reign of Emperor Daizong's son Emperor Dezong, Pei Du passed the imperial examinations and the special examination for grand speech. He later further passed special examinations for those who could properly criticize the government. He was thereafter made the sheriff of Heyin County (河陰, in modern Luoyang, Henan), and thereafter was made an imperial censor with the title "Jiancha Yushi" (). At one point, he submitted a secret petition that criticized those who were powerful due to their associations with Emperor Dezong, and thus was sent out of the capital Chang'an to serve as an administrator at the Henan Municipality (河南, i.e., the Luoyang region) government. He later became an imperial archiver (起居舍人, "Qiju Sheren").
