Kong Zi was a philosopher who proposed a socio-political-moral philosophy based on benevolence, righteousness, propriety, wisdom, and sincerity. He aimed to create an ideal, harmonious society with well-ordered structure and citizens with mutual obligations. Kong Zi transmitted ancient wisdom through instruction, rather than proposing new ideas or religion. His teachings were recorded in Lun Yu as instructive sayings between Kong Zi and his disciples. Key concepts in his philosophy included Ren (benevolence or goodness), Zhong (rectitude), Yi (duty), Li (ritual propriety), and Zhi (wisdom and virtue).
