When Zhang Zi asked about learning, Lu Zi said that he was suspicious and cautious, and the rest were few and far between.

Zhang Zixue Gan Lu Confucius said, "If you hear more doubts, if you are cautious about the rest, you will be rare." If you see more dangers, if you are cautious about the rest, you will regret it. If you don't say anything, you will regret it, and Lu is one of them. "

-"The Analects of Confucius is Politics"

Zhang Zi wants to learn how to get a formal position. Confucius said, "Listen more, put aside doubts first, and be careful with the rest and make fewer mistakes;" Read more books, put aside doubts first, and do the rest carefully to reduce regrets. Say less mistakes and do less regrets, and the official salary is here. "

Cheng Zi said in "Notes to Four Books and Chapters": "If you cultivate heaven, you will be honored, and if you are cautious, you will be generous. Lu Zhishen, the son of Zhang Xuegan, told him to set his mind at ease and not to move for the benefit of Lu Zhishen. If Yan Min knew, there wouldn't be this problem. Or it is suspected that there are people who can't get rich. Confucius said that farming is also clumsy, but only those who can do it. "
