This Chinese philosophy tells of how we continue to learn throughout our lives.

This proverb can be translated in a few ways such as “Study has no end,” “Knowledge is infinite,” “No end to learning,” “There's always something new to study,” or “You live and learn.”

The deeper meaning: Even when we finish school we are still students of the world gaining more knowledge from our surroundings with each passing day.

Here is the Lord's Prayer in Chinese from Mathew 6:9-13.

The Chinese text with punctuation is:
Part of 6:9 ...我们在天上的父，愿人都尊你的名为圣。
6:10 愿你的国降临，愿你的旨意行在地上，如同行在天上。
6:11 我们日用的饮食，今日赐给我们。
6:12 免我们的债，如同我们免了人的债。
6:13 不叫我们遇见试探，救我们脱离凶恶，因为国度，权柄，荣耀，全是你的，直到永远，阿们。
Note that punctuation is not included in traditional Chinese calligraphy artwork.

From KJV, this is:
Part of 6:9 ...Our Father which art in heaven, Hallowed be thy name.
6:10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
6:11 Give us this day our daily bread.
6:12 And forgive us our debts, as we forgive our debtors.
6:13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, forever. Amen.

Long ago in what is now China, there were many kingdoms throughout the land. This time period is known as “The Warring States Period” by historians because these kingdoms often did not get along with each other.

Sometime around 279 B.C. the Kingdom of Chu was a large but not particularly powerful kingdom. Part of the reason it lacked power was the fact that the King was surrounded by “yes men” who told him only what he wanted to hear. Many of the King's court officials were corrupt and incompetent which did not help the situation.

The King was not blameless himself, as he started spending much of his time being entertained by his many concubines.

One of the King's ministers, Zhuang Xin, saw problems on the horizon for the Kingdom, and warned the King, “Your Majesty, you are surrounded by people who tell you what you want to hear. They tell you things to make you happy and cause you to ignore important state affairs. If this is allowed to continue, the Kingdom of Chu will surely perish, and fall into ruins.”

This enraged the King who scolded Zhuang Xin for insulting the country and accused him of trying to create resentment among the people. Zhuang Xin explained, “I dare not curse the Kingdom of Chu but I feel that we face great danger in the future because of the current situation.” The King was simply not impressed with Zhuang Xin's words.
Seeing the King's displeasure with him and the King's fondness for his court of corrupt officials, Zhuang Xin asked permission from the King that he may take leave of the Kingdom of Chu, and travel to the State of Zhao to live. The King agreed, and Zhuang Xin left the Kingdom of Chu, perhaps forever.

Five months later, troops from the neighboring Kingdom of Qin invaded Chu, taking a huge tract of land. The King of Chu went into exile, and it appeared that soon, the Kingdom of Chu would no longer exist.

The King of Chu remembered the words of Zhuang Xin and sent some of his men to find him. Immediately, Zhuang Xin returned to meet the King. The first question asked by the King was “What can I do now?”

Zhuang Xin told the King this story:

A shepherd woke one morning to find a sheep missing. Looking at the pen saw a hole in the fence where a wolf had come through to steal one of his sheep. His friends told him that he had best fix the hole at once. But the Shepherd thought since the sheep is already gone, there is no use fixing the hole.
The next morning, another sheep was missing. And the Shepherd realized that he must mend the fence at once. Zhuang Xin then went on to make suggestions about what could be done to reclaim the land lost to the Kingdom of Qin, and reclaim the former glory and integrity of the Kingdom of Chu.

The Chinese idiom shown above came from this reply from Zhuang Xin to the King of Chu almost 2,300 years ago.
It translates roughly into English as...
“Even if you have lost some sheep, it's never too late to mend the fence.”

This proverb, 亡羊补牢犹未为晚, is often used in modern China when suggesting in a hopeful way that someone change their ways, or fix something in their life. It might be used to suggest fixing a marriage, quitting smoking, or getting back on track after taking an unfortunate path in life among other things one might fix in their life.

I suppose in the same way that we might say, “Today is the first day of the rest of your life” in our western cultures to suggest that you can always start anew.

Note: This does have Korean pronunciation but is not a well-known proverb in Korean (only Koreans familiar with ancient Chinese history would know it). Best if your audience is Chinese.
