What does loyalty in the golden mean mean?

According to Xu's interpretation of The Doctrine of the Mean, "Zhong" means observing the principle of integrity impartially, while "Ordinary" is related to "utility". Its primary meaning refers to the common behavior that can be practiced and realized by anyone at any time, any place. Ordinary behavior is excessive or inappropriate behavior. The doctrine of the mean means always abiding by it. The doctrine of the mean, good and moderate. It is the norm and requirement that can best reflect ethics; Many saints, Tessa, have given many descriptions of what is good, but the goodness in life is more real and meaningful. This kindness is manifested in impartial behavior. It is in behavioral life that everyone can practice and should practice to show people's "humanity". In other words, the behavioral life that everyone should practice is the golden mean, that is, the humanity that Confucius wants to establish.
