The so-called "mean" by Confucius doesn't mean "compromise" but a "moderate" and "just-right" way when understanding and handling objective things. Confucius advocated that this thought should not only be treated as a way to understand and deal with things but also be integrated into one's daily conduct to make it a virtue through self-cultivation and training. The Doctrine of the Mean is not only the core of Confucianism but also an important component of traditional Chinese culture. From the time it came into being to the present, it has played an invaluable role in the construction of national spirit, the transmission of national wisdom, and the development of national culture.
