What does it mean that knives will rust if they are not sharpened, and people will fall behind if they don't learn?

It means: if you don't sharpen your knife for a long time, it will rust, just like others. If you don't study for a long time, you will fall behind. It means to persevere in everything you do, and you will be more skilled in your work. Even if you are proficient in a subject, if you don't actively practice updating your knowledge every day, you will have a deserted day.

1, keep pace with the times, never too old to learn.

2, inspire people to forge ahead, don't be lazy, just like a knife needs to be honed diligently, and people need to study diligently to make progress.

3, a person, if you don't strengthen learning, can't master the latest knowledge and skills, will be slow to respond to the environment, can't adapt to the changes in the environment, and finally will gradually become barren, until being eliminated by society.

First, "business"

Fang Zhongyong, a native of Jinxi, is cultivated in the world. Zhong Yongsheng lived for five years and didn't understand books and tools. Suddenly he cried for it. The father, on the other hand, borrowed from the side and approached it, that is, four sentences of books and poems, which were named after themselves. His poems were written for adoptive parents and families and passed down to a scholar in a township. Nature refers to things as poetry, and its arts and sciences are considerable. People in the city are very surprised. They are a little nicer to their father or beg with coins. My father's interest is natural, and he will always pay tribute to the city people and let him be ignorant.

I've been listening for a long time. In Ming Dow, it has been twelve or thirteen years since our ancestors went home and saw them at my uncle's house. To write a poem, you can't call it the smell of the past. Seven years later, I went back to my uncle's house from Yangzhou and asked him, "Everyone has left."

The prince said: Zhong Yong's understanding is also an act of God. It is also blessed, far more virtuous than talents. If a chess piece is owned by everyone, it will not be influenced by others. He is a man who receives heaven, so he is a saint, and he who does not receive heaven is for all; Today's husband is not subject to heaven, and he is not subject to heaven, only for everyone.

Second, translation:

There is a citizen named Fang Zhongyong in Jinxi County whose family has been farming for generations. When Zhong Yong was five years old, he didn't know writing tools. Suddenly one day, Zhong Yong cried for these things. His father was surprised by this, so he borrowed those things from his neighbors. Zhong Yong immediately wrote four sentences and wrote his own name.

This poem aims to support parents and unite people of the same clan for the whole town to watch. From then on, when he was assigned to write a poem, Fang Zhongyong could finish it at once. The literary talent and authenticity of this poem are worthy of appreciation. People in the same county were very surprised by this, and gradually regarded his father as a guest, and some people paid for Zhong Yong's poems.

Fang Zhongyong's father thought it was profitable, so he led Zhong Yong to visit people in the same county every day and wouldn't let him study. I've heard a long time ago. In the era of Ming Dow, I followed my late father back to my hometown and met Fang Zhongyong at my uncle's house. He is twelve or thirteen years old. I asked him to write poems. His poems are not as famous as before.

Seven years later, I came back from Yangzhou and went to my uncle's house to ask about Fang Zhongyong. I replied, "It's no different from ordinary people."

Wang Anshi said: Fang Zhongyong's intelligence is innate. His talent is much stronger than that of ordinary talented people; But in the end, because the education he received the day after tomorrow did not meet the requirements, he became an ordinary person.

He got such a good gift that he became an ordinary person without normal acquired education; Then, can those who are not born smart now, but ordinary people, who have not received the education of the day after tomorrow, become ordinary people?

Refers to a person who was once brilliant and attracted much attention, but later lost his talent and became the same as ordinary people. But also emphasizes the importance of learning the day after tomorrow.
