The famous aphorisms about being shameful in one's own conduct are as follows:
(1) A gentleman cherishes virtue, while a villain cherishes earth; a gentleman cherishes punishment, while a villain cherishes kindness. He who behaves his own way with shame, sends troops to all directions, and does not disgrace the emperor's orders, can be called a scholar. Use the able to ask questions about the incompetent, and use the many to ask the few; if there is something there, if it is not, if it is true, it will be false. If you make mistakes, you will not correct them. A basket of food and a gourd of drink, in a back alley, where people cannot bear to worry, but they will not change their joy when they return. It is a wise thing to return. Being respectful but rude will lead to fatigue, being cautious but rude will lead to arrogance, being brave but rude will lead to chaos, being straight but rude will lead to strangulation.
(2) To say something without mentioning it is called impatience; to say something but not say anything is called concealment; to say it without seeing the color is called blindness. A gentleman is always in competition with others, but a villain is not always in competition with others. Being sensitive, eager to learn, and not ashamed to ask questions is called "literary". If someone likes to be straight but doesn't want to learn, he'll be stubborn; if he's brave but doesn't want to learn, he'll be confused; if he's straight but doesn't want to learn, he'll be crazy. Words of loyalty and deeds of sincerity and reverence, even in a barbaric country, are carried out. If you are not faithful in words and respectful in deeds, how can you do it even if you live in the state?
(3) Isn’t it true that one should learn and practice from time to time? Wouldn’t it be great to have friends from far away? Isn't it a gentleman if a person doesn't know something but doesn't get upset? If you can talk to someone but don't talk to them, you will lose the person; if you can't talk to them, you will lose your words. He who knows does not lose people, nor does he lose words. A true man acts according to right and wrong, regardless of profit or loss; whether he is good or bad, regardless of success or failure; whether he considers eternity or a lifetime. How can one achieve success if one is not committed to virtue and does not have a firm belief in the truth? How can one be destroyed? I will examine myself three times every day: Are I being dishonest in my plans for others? Have you ever left a letter with a friend? Are you not used to it?
