The principle of Confucianism is often referred to as Tao, which is a three-letter Chinese word meaning 'WAY' or 'PATH'. It is a philosophical system developed by the Chinese philosopher Confucius in the 6th century BCE. Taoism emphasizes the importance of living in harmony with nature and the universe, and encourages people to practice self-cultivation and virtue. It also stresses the importance of family and social relationships, and the need to respect and honor one's elders.
