Everyone is familiar with Confucius' famous saying "Stand at Thirty" in The Analects of Confucius, but it is not easy to give an exact explanation. Throughout the ages, there are countless works that annotate the Analects of Confucius, and the interpretation of this passage is not the same. Besides the annotations of The Analects of Confucius and Yu Dan's popular experience, many famous scholars also have their own opinions. Yang Bojun, a famous contemporary writer, "studied every word of The Analects" and "tried to find out the meaning of every word of The Analects". On this basis, he wrote The Analects (2nd edition, Zhonghua Book Company, 1980). Its translation is: Confucius said: "I am fifteen years old and I am interested in learning;" Thirty years old, understand etiquette, and be sure to speak and do things; At the age of forty, I have mastered all kinds of knowledge and will not be confused; At the age of fifty, I learned my fate; At the age of 60, when you listen to others, you can distinguish between true and false and judge right and wrong; At the age of seventy, do whatever you want, and don't think beyond the rules. " He has some explanations for this translation: about "standing", Taber said: "Standing out of courtesy. "Ji's Chapter also said:" If you don't learn etiquette, you can't stand up. Therefore, the words "be polite" have been added to the translation. "Stand" means to stand, and here it means to stand. For the sake of smooth context, it translates as "be sure of something".
