the source is the Analects of Confucius.

To know roughly means to know, and not to know means not to know. This is a wise attitude.

It is suggested that the ancients demanded honesty, which is manifested in learning, that is, knowing means knowing, and not knowing means not knowing. Moreover, this honesty is wisdom, and knowing what you don't understand is an improvement in itself. If you take ignorance as knowledge, it will not only be dishonest, but also affect your progress.

a gentleman is ashamed of his words but not his deeds.

the source is the Analects of Confucius.

it is a shame for a careless gentleman to talk too much and do too little.

It is suggested that in our daily life, we should pay attention to keeping our words and deeds consistent. If we just talk a lot and accomplish nothing in action, we will be regarded as "giants in speech and dwarfs in action" by others.

although a scholar has knowledge, his behavior is intrinsic.

the source is Mozi cultivate one's morality.

A scholar is knowledgeable, but personal practice is fundamental.

It is suggested that Mozi was the most practical person in hundred schools of thought in the pre-Qin period. Both he and his disciples carried out Mohist administrative thought in practice. Since ancient times, many thinkers and scholars have made useful explorations on the issue of knowing and doing. Li Shizhen traveled to many southern provinces, collected folk prescriptions, verified them one by one, and wrote the immortal pharmaceutical masterpiece Compendium of Materia Medica. It is difficult for a person who only relies on book knowledge and lacks practice to become a great scholar.

although the Tao is famous, it is impossible; Small as it is, nothing is impossible.

the source is Xunzi cultivate one's morality.

Although the general distance is short, you can't reach your destination without going; Small as it is, you can't succeed if you don't do it.

It is suggested that any career should be accomplished by practice. The road to success is at your own feet. If you can't walk down-to-earth and immerse yourself in wonderful fantasies forever, you will only accomplish nothing.

if you hear it but don't see it, it will be ridiculous; See it without knowing it, although knowledge will be false; If you know what you are doing, you will be trapped.

the source is Xunzi's Confucianism.

I have heard about it without seeing it with my own eyes. Although I have heard a lot, many of them are bound to be wrong. See but can't understand, although remember, there will be many is false; Knowing and not implementing it, although rich in knowledge, is bound to encounter problems.

It is suggested that in the eyes of the ancients, hearing, seeing, knowing and acting are the four ways to know things, but acting is the most important. Because "practicing" can not only test the knowledge obtained through the first three ways, but also further promote the understanding and grasp of the knowledge learned.

those who are good at saying the ancient times must be restrained, and those who are good at saying the heavens must be levied on others.

the source is Xunzi's evil nature.

people who are good at talking about ancient times must look for evidence in the present, and those who are good at talking about heaven must look for proof in personnel.

Tip No matter what you say, if you want others to believe in yourself, you must have sufficient evidence. Evidence often shows the relevance of things, so we must look at the problem from a developmental and dialectical perspective.

be careful what you say but not what you do.

the source is the Book of Rites.

Be careful in your general remarks and careful in your actions.

The sentence "Prompt" warns people that a cultured and moral person should be responsible for his words and deeds. Therefore, he should think carefully before "speaking" and "acting", and never act rashly on impulse.

a gentleman is strong in learning and practice.

The source is Yang Xiong's "Fa Yan Self-cultivation".

Moral people encourage themselves to study and act hard.

It is suggested that both learning hard and practicing hard require a person's perseverance. To study hard, you need to study hard, apply what you have learned to your life practice, and at the same time, think carefully and combine what you have learned with what you have used. Therefore, learning is not the ultimate goal, but applying what you have learned is more important.

seek truth from facts.

the source is "Hanshu Hejian Xianwang Liu Dechuan".

the general idea is to study from objective facts and get the law.

It is suggested that Liu De, the king of Hejian, is the younger brother of Emperor Wu of the Han Dynasty. He is studious all his life and does not like boasting. The biggest hobby in his life is to collect ancient books. When people send good books to him, he always asks someone to copy them, then gives them to others and keeps them for himself. Yan Shigu, a native of the Tang Dynasty, commented that his behavior was "seeking truth from facts", which meant that all the ancient books he collected were really good books, and the contents in the obtained ancient books were also in line with the ancient facts. This is the original intention of "seeking truth from facts". Later generations extended this sentence to mean that everything should respect the facts, proceed from reality and speak according to the facts.

seeing is believing.

the source is the biography of Han Zhao Chongguo.

it's better to see it with your own eyes if you hear it a hundred times.

It is suggested that although "hearing" and "witnessing" are the main ways for human beings to acquire knowledge, in many cases, the truth of what they hear is doubtful, because they are often deceived by rumors, and only what they see with their own eyes is more true. "Hearing is false, seeing is true", which is exactly the truth.
