Why did Confucius hope to advise a ruler?

Confucius hoped to advise a ruler because he harbored a lifelong dream of emulating the Duke of Zhou by putting his political ideas into practice to restore moral order to a fragmented world.1

He believed that government should be based on moral persuasion and exemplary virtue rather than legal constraint or the threat of punishment. By serving as a professional adviser, Confucius aimed to guide rulers to become moral leaders whose character would influence the people like the wind blowing over grass, thereby fostering a flourishing, harmonious society. He viewed politics as a "rectification" of conduct, where a ruler's own self-cultivation and adherence to ritual were essential for achieving political stability and enduring peace.213
