There are eight officers responsible for making sacrificial presentations to Confucius' disciples, comprising the Philosophers of the east and west, the Assistants of the east and west, the Ancient Sages of the eastern and western corridors, and the Scholars of the eastern and western corridors (hereafter collectively referred to as the Sages and Scholars of the Eastern and Western Corridors). These eight officers are led by deacons to hand-washing stations on either side of the Da Cheng Hall and, after the washing has taken place, they are led to their positions in front of the Assistant Sacrifice Officers, facing the Da Cheng Hall.
Most of the Collateral Presentation Officers are either elected representatives or hold the positions of responsibility in the local government or the education system.
