What is the difference between contrast Confucianism and neo Confucianism?

Confucianism, founded by Confucius, emphasizes moral virtues, social harmony, and proper conduct within relationships, focusing on traditional values and rituals. Neo-Confucianism, which emerged in the Song Dynasty, builds upon these principles by integrating metaphysical concepts and addressing the nature of reality and the self, influenced by Buddhist and Daoist thought. While both schools prioritize ethical living and societal order, Neo-Confucianism offers a more philosophical framework that explores the nature of knowledge and existence.
