In the Song Dynasty, college students usually served as the secretary of the emperor and were senior officials who assisted the emperor, but their specific responsibilities and status would change with the changes of different historical periods and official systems.

In the Northern Song Dynasty, college students were generally responsible for drafting imperial edicts, serving the emperor and preparing consultants for the emperor. At the same time, they also hold other official positions, such as participating in politics (equivalent to deputy prime minister). In the Southern Song Dynasty, with the weakening of the power of officials, the duties of college students were more focused on drafting imperial edicts, proclamations and taking charge of foreign affairs.

Generally speaking, the university students in Song Dynasty are all senior officials, whose duties involve politics, culture, diplomacy and other fields, which are equivalent to modern senior administrative officials. But the specific positions and ranks need to be analyzed according to the historical period and official system.
