The Secret of Bailudong Academy, that is, the Learning Rules of Bailudong Academy, was written by Zhu, a scholar in the Southern Song Dynasty. The main contents are the teaching purpose, the principle of running a school and the quality that students should achieve. Zhu emphasized that the teaching purpose of Bailudong Academy is not to ask students to read widely, memorize and write gorgeous articles in order to gain fame and fortune, but to ask people to learn Confucian classics, cultivate one's morality and govern the country and become useful talents to society. The core content of education is to study and study the principles advocated by Neo-Confucianism, cultivate body and mind, and thus achieve the ultimate goal of consciously observing. Learning should be carried out in the order of learning, asking, thinking and distinguishing. From their own point of view, from the perspective of social harmony and order, they regard training their self-cultivation, handling affairs and accepting things as the criterion of practical life and ideological education. The above content combines the world outlook, political requirements, educational purposes and learning and cultivation methods.

This educational theory and some teaching measures derived from it formed the school-running norms of Neo-Confucianism in Song and Ming Dynasties. "Revealing Bailudong Academy" soon became the unified academic rules of academies in the Southern Song Dynasty, the model of academic rules of academies in Yuan, Ming and Qing Dynasties, and influenced all kinds of official schools at all levels, becoming the national school-running standard. Wang Yangming, a great educator in the Ming Dynasty, also spoke highly of this learning law: "The husband is the way to learn, and the rules of Bailuyuan are exhausted" ("Preface to the Collection of Ziyang Academy").

From its actual achievements, it is revealed that Bailudong Academy has played an irreplaceable role in popularizing the mass education proposed by Confucius and improving the quality of the people. In particular, the separation between education and being an official, and the separation between personal quality and wealth and splendor constantly inspire scholars to get rid of the temptation of secular imperial examinations and the temptation of fame and fortune in articles. In the Southern Song Dynasty and the Ming Dynasty, many people with lofty ideals gave their lives to protect their country and defend their country, and they did not covet the temptation of various high officials and generous salaries put forward by Yuan Qing. They would rather defend the summer, defend themselves and lay a healthy foundation for the rejuvenation of China. In Song and Ming Dynasties, imperial examinations were very popular. In this case, the revelation of Bailudong Academy held high the core of Neo-Confucianism in the Song and Ming Dynasties, and held high the banner of righteousness, which really played an indelible role.

However, its narrowness is indeed extremely obvious, and its significance lies in the existing knowledge, which hinders the research and absorption of various natural disciplines, physics, chemistry and other knowledge, and also hinders the research of other countries, including the occupation and management of a larger territory. Especially in the early Song and Ming Dynasties, navigation technology was far ahead of the western era. Neo-Confucianism has indeed hindered the expansion of the country and the further prosperity of society. If the Song and Ming Dynasties expanded to Southeast Asia, Africa and America, even if the Central Plains fell, the expanded land would retain the flame of civilization.

"The Secret of Bailudong Academy" Original: Father and son are related by blood. Both monarch and minister are righteous. Couples are different. Young and old are orderly. Friends have letters. The purpose of the right five religions. Yao and Shun made a covenant for Stuart and respected the five religions, that is, this is also the case. Scholars learn this. And his learning order is also five, which is different from the left: erudition. Interrogate it. Think about it. Distinguish clearly Do it. Correctness is the order of learning. Learning, asking, thinking and distinguishing are so poor. If a husband keeps his word, he will cultivate himself well, he will do things and suffer, and he will have his own needs, which is different from the left: keeping his word. Be respectful. Punish repressed desires. Move and patch. The key to correct cultivation. Just do what you want to do, not what you want to do. Do what you know, regardless of merits and demerits. The key to doing things correctly. Don't do to others what you don't want them to do, but do whatever you want. The key to correct connection. Xi plagiarized the views of ancient sages, so he taught people the meaning of learning. Don't you just let them reason, fix their bodies, and then push others? It's not just about remembering them, writing poems, gaining fame and gain benefits. People today are all scholars, but they are all wrong. However, the method of sages teaching people exists in the classics, and people with lofty ideals should be familiar with it, ask questions and distinguish them after careful study. If you know it's natural and blame is inevitable, then the husband's rules are forbidden, and you have to wait for others to set it up before hugging. In modern times, there are rules in learning, and scholars are shallow. And it is the law, and it may not be the meaning of the ancients. Therefore, it is no longer necessary to apply it to this hall, but take the sages as the big end of learning, list them as positive, and expose them. When you think about the cloud, those who are afraid of it will be stricter than the other one. If not, or abandoned by this statement, then the so-called rules will be taken away and will not be solid. You saw it, too.

Revealing Bailudong Academy: There should be blood relationship between father and son, courtesy and righteousness between monarch and minister, deep love between husband and wife, difference between inside and outside, order between young and old, and good faith between friends. This is the outline of the "five major religions". It is this "five religions" that the sage Yao Shun asked Situ Qi to enlighten the people. Students learn these five religions in five orders. Extensive study, serious questions, careful thinking, clear distinction, faithful implementation. This is the order of learning. Learning, asking, thinking and distinguishing have exhausted the truth of things. As for faithful implementation, we should know the principles of self-cultivation, handling affairs and accepting things, and also have our own essentials. Speak faithfully and behave respectfully; Restrain anger and desire; Correct your mistakes and continue to do good deeds. This is the principle of self-cultivation. Correct yourself with courtesy and righteousness, and don't pursue material interests; Strive to publicize and clarify the world, regardless of personal gains and losses. This is the principle of doing things. Don't let others do what you don't want to do; If you don't achieve your goal, find the reason from yourself. This is the principle of the connection of things. In private, I pay attention to the ancient sages teaching people to read and study, only to make people understand the principle of propriety and justice, to cultivate their body and mind, and then to push themselves and others, not to recite poems and pursue fame and gain. Today, some students go against the teachings of the saints. The laws of sage education are recorded in the classics. Ambitious people should be familiar with, ponder, interrogate and distinguish. If you know that this is a natural principle and you must use it to restrain yourself, then why wait for others to set the rules before you do it? Although modern schools have school rules, they are not enough and do not conform to the wishes of sages. Therefore, our college has formulated another study rule. Stick the basic principles of sages teaching people to read and study on the lintel, and ask everyone to study together, observe and restrain themselves. Only when they are strict will they be afraid. I hope you can remember them firmly.
