Confucius
Confucius briefly served as a minister in the state of Lu, but his lasting influence on civil service came through ideas: he argued that government posts should go to the virtuous and capable rather than the nobly born, a principle that shaped the examination system China built a millennium later.
Sima Qian's Records of the Grand Historian recounts that as Lu's acting chancellor around 500 BCE, Confucius watched Duke Ding accept a gift of eighty dancing girls and fine horses from the rival state of Qi, then skip court for three days running to enjoy them. Confucius resigned his post over the ruler's neglect of state duty and left Lu to spend the next fourteen years wandering between courts, teaching whichever ruler would listen.
“A leader distracted from the work of governing forfeits the loyalty of the officials meant to serve that work.”
