One of the most famous people in ancient China was a wise philosopher named Confucius (circa 551-479 BC). He sometimes went by the names Kong Zi though he was born - Kong Qiu - styled Zhong Ni. He was born in the village of Zou in the country of Lu.
This chinese man was a well-known leader in philosophy and he also made many wise phrases and theories about the law, life, and the government. Philosophy is a kind of a system of ideas and thoughts that talk about the human's behavior, the rules that you should follow to make a successful life, and about the government.
In other words, it's about thoughts and theories that teach other people lessons about principles, or rules, about life and it also teaches you a moral ( sort of like the morals that are at the end of a fable). Confucius is famous for his philosophy because he made many wise sayings in ancient China that helped many people learn about nature, the world, and the human behavior. He also helped the government and the emperor by teaching them lessons on how the emperor should rule his kingdom successfully.
