Scholar-officials who entered civil service through examinations acted as executive officials to a much larger body of non-ranked personnel called lesser functionaries. They outnumbered officials by four to one; Charles Hucker estimates that they were perhaps as many as 100,000 throughout the empire. These lesser functionaries performed clerical and technical tasks for government agencies. Yet they should not be confused with lowly lictors, runners, and bearers; lesser functionaries were given periodic merit evaluations like officials and after nine years of service might be accepted into a low civil service rank. The one great advantage of the lesser functionaries over officials was that officials were periodically rotated and assigned to different regional posts and had to rely on the good service and cooperation of the local lesser functionaries.
