The famous saying "You can't be clear-minded unless you are indifferent, and you can't be far away unless you are quiet" comes from Zhuge Liang's Book of Commandments. \ r \ nA gentleman's trip is to cultivate one's morality through quietness and morality through frugality. Not indifferent, not clear-minded, not quiet, not far away. If you study quietly, you must learn. If you don't study, you can't learn widely. If you don't have ambition, you can't succeed. You can't be energetic if you are slow, and you can't cure sex if you are dangerous. Years go with the times, meaning goes with the days, and then they become withered, and they don't meet the world, and they are sad to stay in the poor house. What will happen? \r\n\r\n \\ "If you are indifferent, you will not have a clear vision, and if you are quiet, you will not be far away." It's from the Book of Commandments written by Zhuge Liang to his 8-year-old son Zhuge Zhan at the age of 54. This is not only a summary of Zhuge Liang's life experience, but also a requirement for his son. Here, Zhuge Liang used the sentence pattern of \ "double negation \", and expressed his teachings and infinite expectations for his son in a strong and euphemistic tone. In modern words: \ "If you don't look down on the fame and fortune in front of you, you won't have a clear ambition, and if you can't concentrate on your study calmly, you won't be able to achieve your lofty goals".
