Excerpt from the original text: Ceng Zi's Seventy Years of Learning is famous all over the world. Xun Qing began to study abroad at the age of 50. He is still a Confucian scholar. Gong studied Spring and Autumn Annals in his forties, so he became prime minister. Young and knowledgeable, like the light of sunrise; An old scholar, like a night walk by candlelight, is a wise man who only looks at his eyes.

Translation: Zeng Shen didn't study until he was seventy years old, and he is still famous all over the world; Xun Qing's 50-year-old study tour still became a master of Confucianism; Gong didn't read Chunqiu until he was in his forties, so he became prime minister. Young learners are like the rising sun; Those who study in their later years like to walk at night with candles on, which is better than those who can't see anything with their eyes closed.

Enlightenment and significance:

No matter how old you are, you should study. People always need to learn. It is foolish for people in the world not to study in their twenties and thirties. Young learners are like the rising sun; People who study in their later years like to walk at night with candles on, which is better than closing their eyes and seeing nothing. Therefore, it is never too old to learn. It is better to learn late than early, and it is better to learn late if you don't learn.

You must study early. Many people think that you should study early when you are young, but this does not mean that it is never too late to study at any age.
