Traditional Chinese philosophy is derived from a combination of several schools of thought that were developed based on the teachings of scholars, philosophers and thinkers. The most common sources are Confucianism, Buddhism and Taoism. Chinese philosophy centers around moral ethics, benevolence, wisdom, family and harmony. Heavy emphasis is also placed on honoring ancestors. Chinese philosophy values the "internal" and views human desires as less important. These values are applied to all aspects of Chinese society.
