The civil service test reflected Confucian principles by resulting in the most qualified people working in government. In Confucianism, meritocracy and moral virtue were highly valued, and the civil service test aimed to assess candidates based on their knowledge, skills, and ethical conduct rather than their social status or family background. This system allowed individuals from various social backgrounds to demonstrate their abilities and potentially serve in government positions, promoting social mobility and rewarding those who exemplified Confucian virtues.
