Reflecting often on what one does – this is a way of self-cultivation of virtue advocated by Confucianism. This school of thought holds that as moral integrity is established with one’s efforts of self-cultivation, one needs to constantly examine his words and deeds as well as what he has in mind as a fundamental way of improving himself. Zengzi（505-436 BC) , in particular, stresses that one should everyday reflect many times on whether he has performed duties for others, treated others with good faith and whether he has reviewed what he learned to see if there is any room for improvement.

Zengzi said: “Each day I reflect on myself several times: Have I tried all my best to help someone when offering advice to him? Have I kept my word to my friends? Have I reviewed what I learned?” (The Analects)
