Confucius said, "I am determined to learn five times out of ten, standing at thirty, not confused at forty, knowing my destiny at fifty, obedient at sixty, and obedient at seventy."

Translation:

"At the age of fifteen, I was determined to be a university student; At the age of 3, I can stand on my own feet; Forty years old can be confused; At the age of fifty, I learned the fundamental laws of the physics of heaven; At the age of sixty, everything is heard; At the age of seventy, you can do whatever you want without overstepping the law. "

The original intention was only Confucius' self-growth process, but it was later quoted as a universal behavior track, which was more of a measure and spur, and of course it was unisex. However, according to China's traditional thought, it generally refers to men, such as "the year of thirty" and "the year of no doubt", which are all about men's encouragement and encouragement, and are rarely used for women.
