Confucianism is a Chinese ethical and philosophical system developed from the teachings of the Chinese philosopher Confucius (Kǒng Fūzǐ, or K'ung-fu-tzu, lit. "Master Kong", 551–478 BC)
It is a complex system of moral, social, political, philosophical, and quasi-religious thought that influenced the culture and history of East Asia. It might be considered a state religion of some East Asian countries, because of state promotion of Confucian philosophies.
Cultures and countries strongly influenced by Confucianism include mainland China, Taiwan, Korea, Japan and Vietnam, as well as various territories settled predominantly by Chinese people, such as Singapore. It might be that as many as 1.5 billion people follow Confucian ideals.
In Confucianism, human beings are teachable, improvable and perfectible through personal and communal endeavour especially including self-cultivation and self-creation.
A main idea of Confucianism is the cultivation of virtue and the development of moral perfection. Confucianism holds that one should give up one's life, if necessary, either passively or actively, for the sake of upholding the cardinal moral values of ren and yi.
