I won't go into details about the mistakes made by Confucius in the Analects of Confucius.

Confucius, a thinker, educator and founder of Confucianism in the Spring and Autumn Period, wrote The Analects of Confucius.

One misstep makes a lasting regret, and then a hundred-year-old man.

Yin Mingtang's abandoned poems. Slip: Slip, figuratively speaking, fall or make a serious mistake. Eternity: A long time. Centenarians: People a hundred years later refer to people who have passed away. Once you fall or make a serious mistake, you will regret it all your life. If you don't make this mistake, you will be in the next life. A temporary mistake will cause lifelong regret, and any washing afterwards will be too late to remedy it. These two sentences are mostly used to persuade people to be cautious, so as not to regret after an accident, and can also be used to express deep regret. This sentence is often said to be "a slip of the foot makes a lasting regret, and it has been a hundred years since I turned back."
