The famous sayings about correcting mistakes after knowing them are as follows:

1. If you do good things, I will do them; if you do bad things, I will correct them. From "Zuo Zhuan·The Thirteenth Year of Duke Xiang". People think it is right, so I will implement it. People think it is wrong.

2. He who can make up for his mistakes is a gentleman. From "Spring and Autumn Period, Zhaogong Seventh Year, Zuo Zhuan". Those who dare to correct their own mistakes are true gentlemen.

3. It is not enough to change the past. From "Shuoyuan·Jundao". Correcting after making a mistake is equivalent to not making a mistake.

4. Anyone who has no fault should be allowed to correct it. From "New Book of Tang·Biography of Li Deyu". Everyone will make mistakes sometimes. If we are worried about the mistakes, we should correct them immediately. If it is others who are worried about the mistakes, we should be tolerant and forgive.

5. People always make mistakes, and then they can change; trapped in the heart, balanced by worries, and then act; marked by color, issued by sound, and then metaphor. From "Mencius Gaozi Xia". People often make mistakes and then correct them; their minds are trapped and their thoughts are blocked before they can rise up; a person's thoughts are shown on his face and expressed in his words, and then his thoughts can be understood by others.

6. It is not too late to look after the dog when you see the rabbit; it is not too late to mend the hole of the lost sheep. From "Warring States Policy". After seeing the rabbit, I thought of the hound. It's not too late. After the sheep has been eaten, it is not too late to repair the sheepfold.

7. If you are a person of three, you must have a teacher. Choose the good ones and follow them, and change the bad ones. From "The Analects of Confucius·Shuer". When several people move forward together, there must be their own teacher among them. When they see the shortcomings of others, they will reflect on themselves to see if they are the same, and then correct them. If you understand the strengths of others, you should study hard.

8. A gentleman will move on when he sees something good, and correct when he sees something wrong. From "Zhouyi·Yi·Xiang Zhuan". Really successful people can always clearly understand their own strengths and weaknesses and are good at discovering the power of growth from others. When they see good things in others, they will actively learn from them; when they see shortcomings in others, they will learn from them and constantly improve themselves.

9. Those who know their faults and can correct them are the disciples of a saint; those who hate evil and are too strict will eventually become the disease of a gentleman. From "Evening Talk Around the Fireplace". Those who know what they have done wrong and can correct it are disciples of the saints; those who hate evil to the extreme are ultimately a fault of a gentleman.

10. Those who attack their own evil do not care about the evil of others. If you are an orgynous person, you must be autonomous and sparse. From "Moan Language·Cultivation". People who are busy correcting their own bad habits cannot find time to find fault with others. If you keep talking about others, you must be a person with poor self-cultivation.
