李勉
In 767, Li Mian was in Chang'an to pay homage to Emperor Daizong, and was made the mayor of Jingzhao as well as the chief imperial censor (御史大夫, "Yushi Daifu"). He was said to be simple and solemn in his governance. At that time, the powerful eunuch Yu Chao'en was the monitor of the armies as well as acting principal of the imperial university (國子監, "Guozi Jian"). Due to the authority he had, he was arrogant and demanded respect. Li Mian's predecessors as mayor all, when Yu visited the university, held feasts with food sufficient for several hundred people. When Yu visited the university on Li Mian's watch, however, Li Mian refused — pointing out that as the principal, Yu was the host when he visited the university, and that if he were ever to visit the Jingzhao municipal government, he would surely hold a feast in Yu's honor. When Yu heard this, he resented Li Mian and did not visit the university. Soon, Li Mian was removed.
