What is 40 knowing destiny 50?
This is an ancient description of people at the age of 50, and it is an elegant narrative way. "Knowing destiny" is not resigned to fate and governing by doing nothing, but trying hard without seeking results. Therefore, "knowing destiny at fifty" means knowing the difficulty of realizing your ideal after fifty, so you don't pursue results.
Before the age of 50, I tried my best to achieve something, but after the age of 50, although I still "forgot myself in anger" and "forgot myself in joy", I was indifferent to personal honor and disgrace.
The origin and explanation of idioms;
Confucius said: Nine times out of ten, I am determined to learn. Standing at 30, not confused at 40, knowing destiny at 50, obeying at 60, obeying at 70, and not overstepping the bounds.
He said that at the age of fifteen, he was determined to learn. Fifteen years later, this period was the golden stage of his life, and he was thirty years old. In the best physical condition! (Li: Gao, the best period of life, people spend 30 days in the afternoon, that's what it means), "forty without confusion", forty without confusion?
At fifty, you know your destiny. At fifty, you know the laws of nature. (Fate: law, rules) "Sixty means obedience", and when you are sixty, you can listen to different opinions. At the age of 70, you can do whatever you want, and you won't cross the line.
