Wealth can't confuse his thoughts, poverty can't change his ethics, and power can't subdue his will. Mencius in the Warring States period had a few good words: "Wealth cannot be lewd, poverty cannot be moved, and powerful people cannot be bent. This is called a gentleman. " It means that high officials and rich people can't be bought, poverty and hardship can't be tortured, and violent force can't be threatened. This is the so-called gentleman. These actions of a gentleman show heroism, which we call backbone today. The original text is from: Jing Chun, the second chapter of Teng Wengong, said, "Aren't Gongsun Yan and Zhang Yi real men?" In a rage, the governors are all afraid and the world is destroyed. Mencius said, "A gentleman is a gentleman. Haven't you learned manners? The husband's crown is also the father's life; A woman's marriage is also her mother's order. When you arrive at the door, you will be warned: "When you arrive at your daughter's house, you will be respected and warned, and there is nothing against your master. By the way, be a concubine. Live in the world, stand in the right position in the world and be the best in the world; Success depends on the people, not alone; Wealth can't be lewd, poverty can't be moved, and power can't be bent: this is called a gentleman. 」
