Language "Book of Rites University": "This is called inner sincerity, appearance, and a gentleman must be cautious and independent."

The Three Kingdoms Zhi Wei's "Discrimination of the Empress Dowager": "Only fear the gods, respect and be cautious."

Song Pengcheng's "Continued Mohist Rhino Waving and Making the South of the Yangtze River": "It's a shame to make the singer Qin Yi a prostitute, so I am cautious and independent."

Go back to chapter 20 of "Officialdom in the Appearance": "We who talk about Neo-Confucianism, the most important thing is to be cautious and independent, and to be able to show our innocence and shame at all times."

Li Dalang washes the sand in the first chapter: "Who is the teacher in this closed and uncivilized place, dare not be cautious?" In the original "University", there is a passage that says, "It is not good for a villain to be idle", which means that a villain usually likes to do bad things, but when he meets a cautious person, he tries his best to disguise himself, "covering up his bad things and doing good things." But people's heart and appearance are often the same, and bad ideas can always be expressed in behavior. "People regard themselves as lung and liver", which cannot be concealed by force. Only when they are as sincere as prudent people, they are "external", and "sincerity in China and external" is a main meaning of cautious independence.
