The Tang Dynasty Shu Yuanyu's "Yi Zhudi Shao Ming" mainly talks about the sword being sharpened by itself, but there is no such original sentence. I can't remember which of Zeng Wenzhenggong's articles contains this couplet. The original meaning is that his fifth uncle Nan taught him that he should be hard-working and able to endure hardships. It can't be from Fang Weng's poem

The original text is:

○I asked my brothers to grind stones for their lives (with inscription)

In the past, I traveled up the Wujiang River and found a pavilion. I have a long sword, I know in my heart that it is not reckless, the box contains love, and I have never despised it.

In the autumn of this year in Qin, there is no development, only miserable shading and erosion, and it is only dead iron. I feel ashamed to use a sharp weapon and make it dim.

If this is the case, always keep the heart of tempering in your chest. A few months later, while passing by the foot of Qishan Mountain, I found pieces of stone as green as water, no more than a foot long and half as wide and thick. I tried grinding them with my hands, but found that they were very greasy and the writing was very dense. I noticed the strange stone, so I brought it into the city and asked to discuss its construction. The worker thought it could be used as a whetstone, so I took my sword and struck it. In the first few days, the floating air fell thinly, and there was no joy. Those who want to work are in trouble,

just ask them again. Gong said: "This stone is extremely fine, so it cannot quickly sharpen the iron, but it will accumulate gradually. In less than a month, you will see its true appearance." As he said, the result is a change. The green color is peeling off, like a green snake taking off its scales, the light is shining in the water, and the stars are swimming in it. All the thirty pieces of money I held were broken silently, and the profit I gained was hundreds of times greater. Because of my sigh, I thought that the diamond head was made of five materials,

and cast it into a vessel for the workers. I recovered the first sharp thing and used it to be rigid and sharp. If you don't sharpen it for a while, it is no different from iron. What's more, if it is soft and blunt, but cannot be sharpened, it will turn into dung, earth and ears, and it will be as good as death with iron teeth! This will help people understand.

If you are born in this generation and are not blind, deaf, or mute, then your five constant natures will be complete, and if your nature is complete, then the jackals, wolves, and sparrows will be the same. Or they may blatantly forget to cultivate their reputation and conduct themselves, and instead use arrogant words and unrestrained emotions to get things done, thereby accumulating evil. Day after day, I don't realize it, and I end up destroying my righteous nature and violating the laws of nature. They were the remnants of creation during their lifetime, and they were buried with ashes after death. Isn’t this a failure to live up to the light of the sun and the moon

Jingye!

I have often seen your tendency, and you are truly the one who has achieved your true nature. Kuang Su was able to obey the strict instructions and was willing to take the ancient sage's teachings

, knowing that he must not be a person who lacks morality and buries himself in a weak ethics. However, since I have been in the capital for thousands of years, my rabbit soul is already nineteen years old.

I know that you are afraid that you will not be able to carry out your mission, and you will be trapped in the salary and millet, and you will be begging at other people's doors every day. When I hear this, I feel sad that I have sent you here.

I have accepted and supported you so much. I am also worried that you are poor and have to forget your moral integrity. Because you are confused and confused, you are easy to favor others. /p>

Throwing money into the slave labor leads to laziness in one's career. Thinking about it day and night consumes all my energy. I want to write this as a warning, but I also think that you have not grown up in many years, so I don't want to explain it deeply. Today, I am returning home from Hubei Province. I put stones in the letters, which are the result of sharpening my pen to convey the meaning of the past.

I want you to maintain your rigidity and temper it day and night, so that dust cannot come in by chance. For me, I will keep the integrity of poverty and be careful when it comes to wealth

If I accumulate bad deeds, I won’t worry about my family, I won’t suffer from hand and foot problems, and I won’t feel guilty at the bottom. If you want the three things, don't hesitate. It's just for you to deal with, and it has nothing to do with others. If you don't stop grinding, then the so-called use of cutting gold and stars is too trivial. It's enough to tell you. However, I hope that you always keep grinding stones on your left and right, and you will have to think about it. This is also the meaning of the ancients' Wei Xian inscription. Because the book is a sharpening stone, it is written by Xu Er, and there are words engraved on its side:

The sword's hammer will shine when it is sharpened; the name of a person will shine when it is sharpened. Come on, be my teacher! It's Zhongxi and Jixi,

My fate will never fall!
