Jia Su
At some point, Jia Su passed the imperial examinations in the "Jinshi" class — and did so well that he became well-known. He also passed a special imperial examination for the talented and righteous, and thereafter was made the sheriff of Weinan County (渭南, in modern Weinan, Shaanxi) and an assistant at the Jixian Institute (). He was eventually promoted to be "Kaogong Yuanwailang" (), a low-level official at the ministry of civil service affairs (吏部, "Libu"), and put in charge of drafting edicts.
