"The Romance of the Three Kingdoms" describes that Jingzhou defender Guan Yu despised Sun Quan. When Guan Yu attacked Cao Cao, Sun Quan took advantage of Guan Yu's unpreparedness and captured Jingzhou. Ma Di, a native of Xiangyang during the Three Kingdoms period, served as a soldier in the Shuhan army. When Liu Bei was dying, he told Prime Minister Zhuge Liang: "Ma Di exaggerated and should not be reused." When Hou Ma Di was guarding the street pavilion, he overestimated himself and lost the battle. He lost the street pavilion and was beheaded by Zhuge Liang in tears. This is the historical allusion of "carelessness will lead to loss of Jingzhou, pride will lead to loss of street pavilion". As the saying goes, "Learning from others can help you understand gains and losses." To avoid mistakes like Guan Yu and Ma Su's in dealing with others, one must be modest and prudent, be cautious in words, actions, and independence.

Be careful, as the saying goes, disease enters through the mouth and disaster comes out of the mouth. Therefore, how to eat and how to speak are very important. People often say that you can eat randomly (even if you get sick from eating, it is your own business), but you can't say nonsense (because the audience is others). Therefore, a person must be particularly careful when speaking, and remember that "the words are left on the tip of the tongue, "Things should be done according to etiquette"; "A good word is warm in winter, but a bad word is cold in June"; "Good words are not the icing on the cake, and bad words are not the icing on the cake"; "Don't speak short words in front of dwarves"; "Someone wears a long gown. "It's a long story, no one listens"; "Others' praise is like a flower; one's own praise is like dregs of tofu"; "Lobbying is harmful to morality, talking too much is hurtful to one's soul, and if not wise, it will mislead oneself and others." These are classic sayings and slang proverbs. I once read an enlightening motto about "how to say things" from a newspaper: "Big things - speak clearly; small things - speak humorously; urgent matters - speak slowly; other people's matters - speak carefully Talk; your own things - listen to what your heart has to say; happy things - say it according to the situation; sad things - don't talk about it in person; uncertain things - say it carefully; things that haven't happened - -Don’t talk nonsense; things that can’t be done – don’t talk nonsense; things that hurt people – don’t say them; things about the present – ??say them carefully; things in the future – talk about it in the future.” This is true for a person under any circumstances. , in what environment, in front of what objects, whether you should speak, what words should be spoken, and how to control the way, speed and rhythm of speaking are all very instructive.

Act with caution, "The Analects of Confucius" writes: "Ji Wenzi thought twice before acting. When Zi heard this, he said: 'No more, it's okay.'" "Water Margin" tells: "Lin Chong admonished: 'Brother, it's difficult to think about something, so think twice before acting. '" "Yu Shi Ming Yan" says: "Be patient, you need to think twice before acting." It can be seen that a person must think deeply, consider carefully, and anticipate before taking action. To achieve results or consequences, we should not act rashly, act arbitrarily, or act blindly and hastily. Whether in history or in reality, cases of impulsive punishment are common. Also, failure to act carefully will eventually destroy your great virtue. Even in the small details of life, you must act cautiously, otherwise, your own character will be destroyed. What is particularly important to remember is that you can do hundreds of good deeds and do no evil. "Debt in the Next Life" puts it well: "You know what is true and what is hidden in your actions. Who can ask about the causes of misfortune and good fortune? Good and evil will be rewarded in the end. It is just a matter of whether it comes early or late."

Shendu, in the Tang Dynasty In King Luo Bin's "Yinghuo Fu", there are two poems: "Like a gentleman, he has the right way to go into a dark room and not deceive." People often use the idiom "Don't bully the dark room" to express the meaning of the poem, that is: stay where others can't see you, and don't do bad things. Throughout the ages, all ambitious, knowledgeable, and promising people have been able to "not deceive the darkroom", "be cautious and abide by the Tao", and take it as a warning not to indulge in power, money and beauty. Anyone who is addicted to sensual things like dogs and horses will lose his ambition by playing with things. If a person wants to truly grasp himself, he must be self-respecting, self-reflective, self-disciplined, and self-disciplined. In this way, we can truly be independent, behave seriously, be upright, and be a person who is free from vulgar interests, a noble person, a pure person, and a moral person.

Be upright in words and deeds, and be a person of high moral character. Walking alone is worthy of the shadow; sleeping alone is worthy of the quilt. Being careful with your words, actions and independence is actually a kind of moral cultivation. And those who are virtuous will shine, and virtuous people can carry things. In other words, only people with high moral character can truly bear the heavy responsibility of doing great things.
