Jia Su
Early in the "Taihe" era (827-835) of Emperor Jingzong's younger brother Emperor Wenzong, Jia Su was recalled to the capital Chang'an to serve the deputy minister of worship (太常少卿, "Taichang Shaoqing"). In 828, he was again put in charge of drafting imperial edicts. In 829, he was made "Zhongshu Sheren" (), a mid-level official at the legislative bureau of government (). In 830, he was put in charge of the imperial examinations, and after the roll of examinees who passed the examinations were issued in 831, he was officially made the deputy minister of rites (禮部侍郎, "Libu Shilang"). While serving at the minister of rites, he oversaw three classes of imperial examinees, and selected 75 of them for passage. It was said that among the 75 were many future high-level officials. In 833, he was made the deputy minister of defense (兵部侍郎, "Bingbu Shilang"). In 834, he was made the mayor of Jingzhao Municipality (京兆, i.e., the Chang'an region), and was also given the honorary title as chief imperial censor (御史大夫, "Yushi Daifu").
