During the Zhou Dynasty Taoism (also spelled Daoism) and Confucianism developed—the two most important Chinese philosophies. The great Chinese philosopher Confucius developed a way of life called Confucianism. Confucianism says that all people can be taught and improved if they do the right things. People should focus on doing the right thing for others, make family the most important, and respect elders of society. Confucianism is still important today, but it did not become widely followed in China until the Han Taoism Symbol of Yin YangDynasty. The founder of Taoism was named Laozi. Taoism is all about following the "Tao", which means the "way" or "path". The Tao is the driving force behind all things in the universe. The Yin Yang symbol is usually associated with Taoism. Taoists believe you should live in harmony with nature, be humble, live simply without too many possessions and have compassion for all life. These philosophies are different from religions because they don't have an all powerful god or gods, although the idea of ancestors and nature are often treated like gods. The power of the emperor was also related to religious beliefs. The Zhou talked about the Mandate of Heaven as the law that allowed Chinese emperors to rule—it said that the ruler was blessed by Heaven to rule the people. If he lost the blessing of heaven he should be removed. Things that proved the ruling family had lost the Mandate of Heaven were natural disasters and rebellions. For example, if a draught or flood was particularly bad, people may begin to think the ruling family had lost the Mandate of Heaven.
