Confucianism is a philosophy that emphasizes ethics and human relationships. It originated from the teachings of the Chinese philosopher Confucius. Some key aspects of Confucianism include focusing on relationships between ruler and subject, father and son, husband and wife. The Confucian classics include the Book of Changes, Book of History, Book of Poetry, Book of Rites, and Spring and Autumn Annals. Confucius lived from 551-479 BCE and taught ethics and morality. Neo-Confucianism incorporated Buddhist and Daoist ideas into Confucian philosophy during the Song Dynasty in China.
