During the Han Dynasty, the three highest civil posts (三公) were 太師, 太傅 and 太保 respectively. These were the three highest civil positions at the time (modern equivalent ~ White House Chief of Staff or prime minister), and were roughly equivalent in rank to the subsequent position of 宰相 (Chancellor of China). 太師 was the most senior of the three.
