Abstract
There are three explanations of the sources of virtue in the history of Chinese traditional ethical thoughts. The first source is tian Dao, the second is xing Dao, and the third is ren Dao. These explanations not only demonstrate the unique wisdom of ancient Chinese thinkers in constructing morality, but also have special revelations for us to comprehend more accurately the Chinese traditional morality, to clear up the wrong ideas about morality that have formed since modern times, to make virtue 'present' instead of 'latent', and to construct a moral society.
