Be strict with yourself, keep the internal and external consistency of conduct, and be consistent with others, especially when you are alone, be careful that some unreasonable or dark ideas breed in your heart; Be lenient with others and pay attention to maintaining the dignity of others when they do something wrong. Innocent problems need not be pointed out in front of outsiders. The word "cautious independence" comes from The Doctrine of the Mean: "Destiny is nature, frankness is Tao, and cultivation is teaching. Tao can't be separated for a moment, and non-Tao can be separated. So a gentleman is wary of what he can't see, and fear is almost unheard of. Don't be invisible, don't be insignificant. Therefore, the gentleman is cautious and independent. " )
