Li Yong is an accomplished thinker. He has been studying, teaching and writing books all his life. A notable feature is that he emphasizes the word "real" and pays attention to actual revision. He said that the so-called actual combat training is to be able to "repent and turn over a new leaf" and improve self-cultivation awareness. He believes that there are many reasons why the ancients talked about self-cultivation, which are not as clear as the words "repent and turn over a new leaf". He said: the purpose of "repentance and rehabilitation" is to make people become real people. This is because the common fault of people now is that they don't know the basic truth of being a man, and their sense of shame is exhausted. Therefore, he said, people can no longer talk empty words, but should pay attention to "repentance and rehabilitation", cultivate a sense of shame and know what shame is. Only when a person has a sense of shame can his heart be sincere, talents are real people, and learning is real learning.

Li Yong not only attaches great importance to practical training, but also attaches great importance to practical learning and practicality. He said that a person should not only read books that are beneficial to physical and mental cultivation, but also read books that are useful for practical work and for governing the country and the world. He believes that only by reading these two books can a person have both morality, talent and talent.

Li Yong also believes that reading should not be biased, even if it is different from learning, as long as it is beneficial to people's physical and mental cultivation, it may be adopted. He once said: there are some truths between heaven and earth, which the sages in front have not said, but the sages behind have said; Some Confucian scholars didn't say it, while those non-Confucian scholars occasionally said it. We shouldn't waste words because of people. As long as their words are beneficial, we should accept them, not refuse them. Based on this understanding, he pointed out that we should not only read the Complete Book of Agricultural Administration by China and Xu Guangqi and the Water Conservancy Law by Xu Faren, but also read the Taixi Water Law by the Italian missionary Xiong Sanba. He advocated that the main points of these books should be widely posted in rural areas and traffic arteries, so that ordinary people can see them, let them know how to operate and fully tap the potential of land. Li Yong's academic outlook embodies his open-minded attitude and the spirit of seeking truth from facts.

Li Yong not only opposes the academic portal view, but also opposes the traditional view that truth can only be monopolized by saints and ordinary people can't find anything. He said: the truth between heaven and earth was not discovered by the sages in front, but by the sages behind; Don't think that people born in poverty can't find the truth because smart people can't find it and ordinary people find it. He cited many ancient people with humble origins and scholars of the Ming Dynasty as examples, explaining that no matter sages or ordinary people, they can achieve something in learning as long as they are willing to study hard. Today, Li Yong's advocacy of emancipating the mind and daring to explore the truth is really commendable.

Li Yong not only advocated reading useful books, but also advocated applying what he had learned and paying attention to implementation. He once said: keep your feet on the ground and don't step on empty steps. If a person only talks about theory and despises implementation, it is like walking empty, and it is inevitable to fall. This style of emphasizing practice over empty talk is an important feature of Li Yong's practical learning thought.

Its tomb is in zhouzhi county, Shaanxi Province.

Attachment: Repentance and Rehabilitation

The nature of heaven and earth is precious. People, the spirit of heaven and earth become one, that is, the nature of heaven and earth. The amount of this property is as great as heaven and earth; The spirit of this nature is in harmony with the sun and the moon. This is the best of all evils, and the essence is flawless; Most people are obscured by temperament, led by lust, bound by customs, changed by the times, induced by knowledge and lost consciousness. Gradually stripped of erosion, moved to the stream of consciousness, so mean and perverse, willing to fall into the family of villains, even people, what they do is not far from animals. Is this the evil of nature? However, although it is in the field of small animals and animals, those who are naturally integrated with heaven and earth, the sun and the moon are always at the end of the solid; People are not as confident as they are, so they ignore their ears. Like a mirror covered with dirt, the light body is everywhere; Another example is that the orb is trapped in a cesspit, and its treasure is not lost. If scraping, grinding, washing and picking can be added, the dirt will be gone and the treasure of the light body will be the same as before. How can we be less damaged?

Those who are born beautiful and refuse to learn often give up because of one failure. After that, although it is clear that there are many good things to grind and benevolence, I will still blame myself: "I have always been like this." Although I have resumed my good practice, who can I trust? " I don't know the difference between a gentleman, a villain, a man and a beast, only in a moment. If you have always been an animal, once you change your picture from now on, you are a person; I have always been a villain. Once I change my picture from now on, I will become a gentleman. At this time, not only my relatives love me, but also my friends respect me. Everyone obeys me, even the ghosts and gods of heaven and earth pity and bless me. However, those who put the blame on themselves hardly think about it.

The famous Confucianists in ancient and modern times advocated salvation in different ways: respecting the poor reason, standing first, sacred mind, nature, renaturation, conscience, or understanding everywhere. Although each family has different purposes, the word "repent and turn over a new leaf" can never be found, which will always open the way for people to repent and turn over a new leaf, but it has never been revealed, so it took a lot of breath to give lectures at that time. I think that there is a basis for not directly mentioning the word "repent and turn over a new leaf". The so-called "heart is not used indiscriminately, work is not miscellaneous, Dan Fu has food, and the stone is turned into gold."

Or: "from the previous sects, they all made profound statements and went straight to the holy land to look at people with sages;" Today, my son's words are shallow, and he seems to be too hard on others. Why not? " A Dai said, "otherwise. People who lose their photos because of the bright sun will be covered by clouds, and the sun will shine when the clouds open. Therefore, don't be tired of saints, and reduce them to be virtuous. Isn't it more straightforward and simple to enter the shelter? "

Skeptics said: "The Six Classics and Four Books are vast, among which the essence is hard to describe. Repentance and rehabilitation' is better than its micro-Olympics? "I don't know how easy it is to describe the image of' wind and thunder', the generosity of books, the innovation of books, and the subtlety of Spring and Autumn Annals, so that courtesy is the Tao and joy is the comfort. Confucius said' not afraid' and once said' strict'. Just like Sutong and Qingnang, both of them are effective prescriptions, passed down to save the world's diseases, not to gain something outside the diseases. He said: "Scripture is really the truth of nourishing qi and calming down. Is it just to repent and turn over a new leaf wholeheartedly? "Yu Gong said:" If the son of heaven can repent and turn over a new leaf, the monarch will be extremely built and the world will be peaceful; "If the governors can repent and turn over a new leaf, Hou Duzhen and the country will be governed by it; If the doctor can repent and turn over a new leaf, the minister will be upright and the family will be together; If scholar Shu Ren can repent and turn over a new leaf, his moral career will grow and he will be repaired. How can he be responsible? "

Killing people will cut their throats, and learning will focus on being willing. Repentance and rehabilitation is the key to a thousand saints' further study. If a person has no ambition to be a man, it is good to learn from him.

There are some truths between heaven and earth, for example, the former saints occasionally see less than the latter saints, and the wise or mediocre people occasionally see less than them, but if you use your body and mind, you will become a witness and have ears. Be a mediocre person, ignorant of learning, lonely and uneasy, ready for poverty and sorrow. On the night of rewelding, I suddenly saw this sentence If I can settle down, if I can be selfish, I dare to expose it to my comrades. If you say mediocrity and ignore it, you will still hate poor women's cloth and be willing to freeze yourself.

The elder said, "Life is an official, and most of it is only thirty or fifty years, but standing on the street is immortal for thousands of years." The foolish old man said, "If you give up repentance and turn over a new leaf, you will not be able to stand on your feet or take the right path, but you will be heard by everyone."

People nowadays can't reach the truth of good and evil. Every time they practice a little, they will be blessed and blessed. I don't know that the person who loves heaven and earth the most is from Xiu De. Sheltered by ghosts and gods, it is also the home of good people. If people in the Ming dynasty can repent, then no one is wrong; If you repent in seclusion, you will have no ghost responsibility. From then on, when the moon is full, it is a great shock to the world. You can answer the heavenly heart and pray for eternal life. Why not?

Brief introduction of two song collections

Li Qing (1627- 1705), a native of Shaanxi (this week), was called Mr. Erqu by scholars for his folk songs and water songs. Born in Guanzhong, Li Yong advocated giving lectures all his life and was highly praised by Guanzhong scholars. He, together with Sun Qifeng and Huang Zongxi, was called the three great Confucianism in the early Qing Dynasty, and was one of the most influential educators in the Ming and Qing Dynasties. The educational thought of "Erquji" is very rich, which, in a nutshell, includes the following aspects. (1) Learning Lu Wang's Thought and Learning the Spirit of Zhu Cheng's Neo-Confucianism are very famous educational philosophy works. The so-called "learning marrow" is the true marrow of learning, which is the most important purpose of learning. This paper is a record of a speech given by Li Yong to his teacher, which was compiled according to the teacher's record. There are pictures and notes. The pictures were made by Li Yong himself. This book "Blood Marrow" has pictures and descriptions, and its style is just like Zhou Jiyi's "Too Easy to Illustrate". His book is divided into two parts, one is the ontology of mind and the other is the theory of moral cultivation. In ontology, Xue Sui believes that "the origin of life" (also known as "the origin of spirit") is the foundation of human beings and everything in the world. In fact, this "source of life" or "source of spirit" refers to the "human heart". I think it "fills the world, runs through ancient and modern times, and has no interest in it for a moment." Will get this, heaven and earth I stand, ten thousand people I go out, thousands of sages shoulder to shoulder, once ancient and modern. "This kind of ontological thought inherits Lu Jiuyuan's" original mind theory "and Wang Shouren's" conscience theory ",and advocates that spirit produces everything and everything embodies spirit. This theory of mind and nature emphasizes the domination of personal inner virtue on moral practice. " Everyone has this spiritual source, and he knows it well and can respond with emotion; I don't know every day, so I lose my right. Riding a donkey, watching the donkey call the people. "To this end, the noumenon is doing nothing and doing everything." All-inclusive, all-candle, suitable for all Xian Yi. Therefore, Xue Sui put forward the view that "mindfulness is mindfulness without thinking". The so-called "brainless thought", that is, the thought without material desires, is completely in line with the "natural principle", is "unique and not opposed to things", is a pure natural principle, and has no opposition to reason and desire. The distinction between morality and immorality is not determined by the external process and result of moral practice, but by "thought" and "the desire of rational thought". That is to say, just do what you say and what you see, but do what you can, what you want and what you want. There is something to do, but a gentleman doesn't. "This is an out-and-out subjective moral philosophy, which pushes the asceticism thought of" preserving nature and destroying human desires "to an absolute inner peace, requiring scholars to stick to their own roots and keep their own truth," forgetting reason, forgetting desire, thinking, looking at the mirror and not welcoming ",and only in this way can there be noumenon and the so-called" Juexue ". It's called "Dade Dunhua". Compared with Neo-Confucianism in Song and Ming Dynasties, Kung Fu based on this ontological understanding is very close to Wang Gen's "Xin Zhai", Nie Bao's and Luo Hongxian's "Quietly Returning to Silence" and Zou Shouyi's "Self Fear" in Ming Dynasty. The starting point of kungfu is fasting, which is an important task of "Shende". We should be of one mind, guard against indecent assault, be alert, and safeguard the solemnity of moral spirit. Its basic kung fu is meditation. Why sit still? " The water is clear, the beads are self-evident and the heart is clear, so it must be based on meditation. It is required to meditate three times a day and burn incense in front of it at dawn, noon and midnight, so that the mind can be "quiet and empty-bright and quiet" and "moving and empty-bright and quiet", and seek "neutralization" when the body is undeveloped and developed. It is believed that through meditation, once the realm of "Zhan Zhan Cheng Cheng Cheng, nothing inside and outside" is reached, the "noumenon" can be "endless, both dynamic and static" and its true colors are revealed. " At this point, there is no saint, no life and death. "That is, to achieve the state of pure justice and no one wants it. Xue Sui thinks that this realm is the Six Classics, the University, the Doctrine of the Mean, the Analects of Confucius and Mencius, which leads to Zhou Yimi's "immediate effect", Cheng Yi's "benevolence", Zhu's "respect for the poor", Lu Jiuyuan's "being the first", "to conscience" and Lu Jiuyuan's. Learning this is learning marrow. In addition, even if all the ancient and modern books and works are accumulated, it can't be regarded as learning, but can only be said to be "playing with things." "In a word, Li Yong's" learning essence "pushed the theory of mind and the methodology of" preserving reason and extinguishing desire "of Neo-Confucianism in Song and Ming Dynasties to a completely mysterious subjective spiritual world from the perspective of educational philosophy, which was closely related to his mentality of" avoiding the world alone "and his determination not to cooperate with the Qing court. At the same time, his" learning essence "theory and kung fu were all in the practice of moral cultivation. (2) On the cultivation of mind based on "repentance and rehabilitation" The theory of repentance and rehabilitation in Song Dynasty holds that human nature is "based on the principle of heaven and earth" and "flawless in essence". But because of "temperament, lust, customs and times", he was gradually eroded and moved, so that he degenerated into a villain. Even if he was reduced to a villain, his "nature" did not disappear. " For example, a mirror is covered with dirt, and the county is not absent. "As long as you scrape and wash, the dirt will be gone, and it will still be bright and shiny without any loss. Learning from ancient times to the present, to cultivate one's morality and cultivate one's sexuality through heart-to-heart talks, is the merit of teaching people to pose and see one's sexuality with a clear mind. Based on this point of view, The Theory of Repentance and Rehabilitation points out: "There are different Confucian scholars who advocate salvation in ancient and modern times. Or take the Lord's respect for poverty as the standard, or the great standard as the first, or the mind as the holy standard, or the nature standard, or the renaturation standard, or the conscience standard, or the local recognition standard, or the cultivation standard, or the Zhi Zhi standard, or the mingde standard. Although the purpose of each family is different, there is always no word' repentance and rehabilitation', which always opens the way for people to repent and rehabilitate. The theory of self-cultivation of mind, marked by "repentance and rehabilitation", affirms the essence of human nature in the original state and thinks that human nature can be changed through acquired acquisition and education, but it comes to the conclusion that "human desire" is absolutely bad and evil. In order to "preserve justice and destroy human desire", it advocates "the road to a new day after its innocence". Li Yong pointed out that the Six Classics and Four Books all talk about the truth of "repentance and rehabilitation". As long as the emperor and the common people can follow this principle, we can achieve the goal of self-cultivation, family management and world peace. Therefore, "repentance and rehabilitation" is the basic knowledge of learning. " This is the key to learning from a thousand saints. If you don't have the ambition to be a man, you will have to learn it. "But, how to put the theory of repentance and rehabilitation into practice? The article points out that if a scholar wants to pay attention to this knowledge, he must "sneak into his mind and check it carefully." "If you have a thought that is not purely intellectual, it is too much, and that is that you should regret it. If there is a breath that involves a little slack, it is not new, that is, it is necessary to shake up. If you are a person who has never studied, you must first check his body, then check his heart, regret his mistakes and stop his follow-up. I also hope that there will be no impure ideas and no interest. This kind of repentance and rehabilitation is a kind of inner introspection and self-cultivation, and it is a way to consciously bind one's body and mind with the shackles of feudal moral spirit. If you think that repentance and rehabilitation make your mind perfect, you will "regret and regret, so that you can regret without doing anything;" "New, new, new." As for the efforts to repent and turn over a new leaf, it is still to sit still, as advocated in Xuemarrow. "We both attach importance to this research. After a long time, day after day, I chased the scholar, but I couldn't do anything, so I had to wait and die. Meditation is the beginning of ancient people's work. "Why sit still? Because "the principle of heaven and earth" can't get together, unless it is quiet, it can't be transcendental. "There is a slight boundary between excess and goodness, and it can't be analyzed unless it is refined." Only by sitting quietly and getting rid of "competing with others" can we "know a few things" and be pure in nature. " Repentance and rehabilitation also lists many examples of ancient and modern people to encourage them, indicating that as long as they repent and rehabilitate, they will have the effect of becoming virtuous. In short, the theory of "repentance and self-improvement" mainly focuses on the moral introspection and self-cultivation of Neo-Confucianism in Song and Ming Dynasties, aiming at teaching people to fulfill their "human desires", making the external feudal ethics completely and consciously internalized into individual moral qualities, and making the temple "perfect" and "sage". (3) In a large number of pages of Song Dynasty Collection, the purpose and function of learning are expounded. The book "Two Stories" points out: "Education must start at school. It can be said that there can be no education at school without education. However, education is not empty talk about benevolence and righteousness, but to understand this heart and embody this principle. "Ancient and modern psychology is the same, but the purpose and nature of learning are fundamentally different. One is to learn for yourself, the other is to learn for others. The so-called "learning to be an excellent official" means "not seeking fame and fortune, not seeking to be abandoned by sages, that is, taking intelligence as the only way to distinguish and having nothing to rely on". And "learn for yourself, only know this heart, do this, and do this." Practice yourself before starting this heart. Check after delivery. It is nothing more than daily use. It's just that discipline ethics can be realized anytime and anywhere. "Li Yong believes that if you want to learn, you should take" for yourself "as the purpose and cultivate one's morality to govern others. Because life is alive, "there must be a career in starting a business, and there must be a career in using the world." Therefore, "all talents are giving lectures, all customs are changing, all chaos is being cured, and all work is going on." "For virtue, for the people, there is no other way." To understand "learning for yourself", we must know the difference between academic truthfulness and falsehood. Erquji criticizes the unclear academic knowledge of later generations and enlightens the supernatural. "My father and brother are supervisors, my teachers and friends are guides, and I am encouraged by the incident. My children's studies have not surpassed fame and fortune. Besides, I don't know why schools should be set up and why reading should be set up. " The academic uncertainty makes "learning for the people" kill the descendants of the world with academics; However, "learning for yourself" is getting worse and worse, "people's hearts are not right" and "governance is not prosperous". Therefore, the Collection of Song Dynasty holds that "learning today is necessary. Academic knowledge makes talents flourish. The population is prosperous, the customs are correct and the governance is harmonious. "The purpose of clarifying academics is to cure chaos. And "the chaos of the world is ruled by the evil of the human heart; The evil of human heart comes from academic brightness, academic brightness and beautiful things. " Here, Li Yong blames the correctness of learning on the rulers' advocacy of learning, and points out that what the modern rulers "add righteousness" is just "testing the text in class for reward". In view of this, Li Yong pointed out in "Important Matters": "The foundation of the husband's world is the people's heart; Nothing in the world is more helpful than reminding people all over the world. However, if you want to awaken people's hearts, you must be academic. This is the top priority today. " What is the academic meaning of "Two Songs"? Or what academic should be used to "remind the world"? This is the so-called "the study of the application of Ming style". In the question and answer, the article pointed out: "those who can understand everything and reach heaven are called Confucianism;" Serving the business of economics and participating in heaven and earth is called learning. " "Confucianism is also applicable to the knowledge of the Ming Dynasty." Specifically, "Taoism is actually Confucianism", "poor theory is general knowledge, and vice versa is general understanding and practical theory; Reach out and things will be done, and Ji Kang will live in groups. Husband is applicable. " In Fuping's question and answer, he also pointed out: "Six Classics and Four Books are also suitable for Confucianism." However, whether reading the Six Classics and Four Books can achieve the purpose of "being clear and practical" depends on the purpose and method of reading. If there is no clear style of study, no matter how deep the research is, no matter how rich the works are, it is just boasting and coquetry. For another example, it is fragmented into many theories and buried in exegesis, "practical for the ears of popular learning." The purpose and method of this kind of learning can't achieve the purpose of "clear and applicable". Reading four books and six classics is unclear, and its method is mainly to pursue "miscellaneous". What is "miscellaneous"? That is, "inexhaustible, not deep." Although you know a lot, it is better to travel far, and this miscellaneous study is also. " All miscellaneous Confucianism, service spirit is useful, trivial matters are useless. "It is not enough for Ming Dow to deliberate, and it is not enough for the world to kill things. It is only in vain." None of these learning methods can be clearly applied, so where are the methods? Although Er Qu Ji was written in the early Qing Dynasty, the rulers of the Qing Dynasty strongly praised Zhu Cheng's Neo-Confucianism, but lashed out at Wang Yangming's studies and tried to belittle them among the scholars. In this case, Li Yong thinks that Yangming's learning and learning are only "applicable to Ming-style learning", and Fuping points out that later scholars are not good at Yangming's learning and learning, and think that Zhu's learning is incompatible with fire and water, which is quite wrong. Yangming school has the function of "clarifying style", while Zhuzi school has the meaning of "application". Therefore, "it is necessary to make the conscience clear to the noumenon, and it is time for the Lord to respect the poor and save the trial." From a little thought to caution, from audio-visual words and deeds to revision, ordinary inside and outside, Yao Jiang and Kao Ting's purpose can not be neglected, and school and school are consistent. "Only in this way can we" clearly apply ". Li Yong believes that whether learning can be based on "clear style and practical use" is related to the bright future of Confucianism. "Confucianists have bright and dark, not only because of the rise and fall of the literati style, but also because of the unity of the people and the world. If Confucianism is clear, scholars will learn it and apply it to the legitimate cause of the Ming Dynasty. Then, people will benefit from it, but why not do it in the world? If Confucianism is gloomy, then the attacker of the scholar, reciting the last skill of the chapter, has no defense, nothing to do and nothing to rely on for the people, but what is wrong with this world? It can be seen that the theory of "clear mind, discipline and self-cultivation" in Erquji is the so-called theory of "clear body and adaptability", and its function and significance lie in "managing troubled times" and "waking up the world". (IV) Teaching contents and teaching plans for the study of "Application in Asana" In "Sports Almighty Learning", learning is divided into "Application in Asana" and "Application". Academics belonging to the Ming School include Xiangshan School, Yangming School, Longxi School, Jinxi School, Cihu School and Baisha School, which are considered as "the Ming School in the Ming School". In addition, there are Er Cheng Quan Shu, Zhu Quan Shu, Zhu Zi's Anthology, Wu Kang Zhai Ji, Xue Du Lu, Hu Jing Zhai Ji, Luo Zheng 'an's Extended Records, Lu Quotations and Feng Ji. These are all "Ming Kung Fu." And pointed out: "From the book of Xiangshan to the book of Cihu, we can understand the nature of the heart, pour it out and read it properly, which can be the great source of Ming Dow. So my husband reads Cheng, Zhu Zhulu, Kang Zhai, and other episodes every day, in order to study hard, protect this post, and try to combine with the ontology, starting from now on. Going to school and studying both inside and outside, consistently, will become a reality. "In addition to the above works, there are Zou Dongkuo Collection, Wang Xinzhai Collection, Qian Xushan Collection, Xue Zhongli Collection, Geng Tiantai Collection, Lu Shen Collection, Xin Fuyuan Collection, Wei Zhuang Qu Collection and Zhou Haimen Collection, which can also be used as reference materials. Applicable works include: University, Supplement to Yan Yi, General Examination of Literature, Lu's Records of Political Affairs, Xin Fuyuan's Hengmenqin and Poetry, Jing Yao's Poems, Wu Beizhi, Shi Jing's Eight Outline and Zi Jian Outline. It is pointed out: "All the above are related to the salty economy, so we should concentrate on studying them one by one. "Judging from the academic works listed above, the so-called" body "of the theory of" Ming Dow's application "advocated by Er Le Ji refers to the cultivation of moral mind, while" use "refers to the application of governing the country and leveling the world and its related politics, military affairs, laws and regulations, farmland, water conservancy and geography. After each book, Li Yong wrote a review, pointing out the nature and significance of each book and its position in "style" or "application". All these reflect Li Yong's academic value orientation. The most obvious thing is that he regards the works of Lu Jiuyuan and others as "Ming style in Ming style", while regards the works of Cheng Cheng and Zhu as "Kung Fu in Ming style", which shows his persistence in "Mind Learning". Li Yong pointed out in his book Answer to Mr. Gu Ningren: "Ming Dow deliberately thought of his body, and when he slaughtered things in the world, he thought he was real and practical. "It is necessary for Ming Dow to deliberately borrow the world to kill things, but only to distinguish between ancient and modern doubtful words, textual research and exegesis, or to seek between words and ears, only to seek the end. It can be seen that although Li Yong talked about the cultivation of Taoist mind, he meant practicality. Especially in the "applicable category", he included books such as Shi Jing Yao, Wu Beizhi, Agricultural Administration Encyclopedia, Water Conservancy Encyclopedia, Taixi Water Law, Geographical Risk and so on, which showed his real concern for practical knowledge. Shi Jing Yao, for example, covers reclamation, water conservancy, salt policy, national planning, selection of generals, training, vehicle system, fire attack and so on. The content of Wu Beizhi includes ancient and modern wars and methods of using troops, among which Sun Zi, Woods, Ji Xiao Shu Xin and Historical Records of Training are all classic works of ancient military strategists. Encyclopedia of Agricultural Administration and Taixi Water Law were both new scientific and technological books at that time. He included them in the teaching materials, indicating that his "applicability" was based on practical application. In the article Reading Times, Li Yong made a very detailed list for scholars, including 34 kinds of books, and mentioned dozens of books for reference. "Erquji" not only lists such a detailed list of books, but also points out the significance of each book. Moreover, in articles such as Guanzhong Academy Convention and Learning Course, according to the difficulty and content structure of teaching materials, teaching procedures and psychological characteristics of teaching, valuable teaching plans are included, and the learning order, knowledge and psychological preparation, teaching methods and so on are specifically explained. On the teaching principles, Hui Yue and Xue Cheng put forward the teaching principles of "striving for innovation", "sitting quietly and clearing the heart", "self-collection", "asking questions and thinking clearly" and "combining". As a masterpiece of China's ancient education, Erquji has its unique ideological content and academic value. In academic thought, he advocated the application of honest and upright style, the application of true style, the study of killing things, the gathering of knowledge and the application of learning as the purpose of reading, and criticized the empty and sparse style of study of scholars at that time, which was both conservative and practical. On the value orientation, he tends to learn from Lu Wang's thoughts, advocate academic compatibility, and transform the educational content under the principle of "clear and applicable". These should be affirmative. However, the moral theories and methods of moral cultivation advocated in Er songji, such as meditation, repentance and rehabilitation, have mysterious idealism and the essence of feudal asceticism, which are incompatible with the anti-Neo-Confucianism enlightenment trend in the late Ming and early Qing Dynasties, showing its backwardness and limitations.
