Liu Minghua looked at the tall and thin talent, and said with a smile: "Then who are you?" When did I say that you don't learn anything? I'm just talking to my brother and complimenting this Lee Chrome brother! ”

"You ......" The tall and thin genius was choked by Liu Minghua, and there was no way to get angry, Liu Minghua really didn't name him just now.

At this time, Li Chrome glanced at Liu Minghua curiously, and saluted forward: "Ah, brother Tai has won the award!" May I ask my brother's surname? Seeing that the brother is confident, can the brother give him some guidance before going down? ”

"Brother Li has said it, under Liu Minghua, I don't dare to say anything, it's okay to learn from each other." Liu Minghua said with a smile.

Liu ...... Liu Minghua? Ah, it turned out to be Brother Liu? Brother Liu, I heard Imperial Physician Wang talk about you, saying that you are too angry. Brother Liu, can you explain in detail what oxygen is? ”

Liu Minghua smiled: "To put it simply, oxygen is an ingredient in the wind. The wind is like a bowl of rice, there are rice, vegetables, oil, and salt in the bowl, and we can only taste it deliciously. And oxygen is like any kind of rice, without oxygen, the fire will not burn. ”

This metaphor is vivid and easy to understand, even though these people in front of him are Tang people who have no knowledge of physics, they still understand it, and there is an expression of "I see" written on their faces.

Li Chrome was the most excited, and hurriedly invited him sideways: "Minghua, please sit down, let's talk slowly." I have a lot of questions that I want to ask someone like Minghua for advice. ”

Looking at his joy, Liu Minghua couldn't refuse: "It's serious, it's serious, don't dare to ask for advice." If I knew. You must know everything, and you must say everything. ”

"Brother Minghua, why do people who carry heavy burdens walk very fast?" Li Chrome asked.

Liu Minghua said with a smile: "Walking with a heavy burden is equivalent to a sudden increase in the weight of the human body, and the downward trend when moving forward is very strong." Narrowing the steps of the step can appropriately reduce this tendency to dump; Quickly stepping on your hind feet can prevent you from actually falling. Therefore, the person who carries the heavy burden always walks with small and urgent steps, which is called a small trot. Short steps when carrying heavy burdens. The speed can be even, so that the burden can also move forward with the person at a uniform speed. If the steps are big and slow, the burden will be pendulum and difficult to pick. This is understandable, right? ”

Li Chrome suddenly realized: "Oh, I see! Minghua. Why does the ghost fire shine? ”

Liu Minghua said: "Why did you ask this question? ”

Li Chrome's face flashed with color. smiled: "Minghua doesn't know. Actually, it wasn't a ghost fire, it was a white thing burning. I was bold enough to spend a few nights in a mass grave outside the city. When the ghost fire came out, I grabbed it in my hand and saw it, it was a white thing. ”

Ghost fire is quite terrifying in modern times, Li Chrome actually dared to go to the mass grave cat, and used his hands to catch the ghost fire, this is not a bold avenue to understand, this is simply bold. Those students, Lan'er, eldest grandson Jiaqing, and Ma Zhou all screamed in surprise. Well

Anyone can be proud of this kind of thing, Li Chrom's eyebrows flew, his voice raised a lot, and he smiled: "Actually, this ghost fire has nothing to be afraid of." Hold it in your hand, hold it for a while, and then go out. If it gets on your hands, it will burn up again, and I wonder if the ghost hands and ghost fires that the alchemists said are likely to be this kind of thing. ”

The ghost hand ghost fire used by the priests to deceive people is to apply some white phosphorus on the hands, and then shake it for a while, using the principle of friction to generate heat, so that the temperature of the white phosphorus rises, and the ignition point of 40 degrees is ignited.

Li Chromium, a Tang man, had such rich associations, Liu Minghua was very surprised: "Brother Li is right, ghost fire is this kind of thing." This thing has a name, it's called white phosphorus. If you want to find white phosphorus, go to the cemetery, where there are many. The burning of white phosphorus will not be as hot as the burning of firewood, and only the monks dare to use it to deceive people. ”

The reason why white phosphorus is more in cemeteries is because the human body contains phosphorus, and after the corpse decomposes, the phosphorus will re-condense together and float in the air, especially in summer, when the temperature is high, it will spontaneously combust, which is the reason why ghost fires often appear in cemeteries.

Liu Minghua not only confirmed Li Ran's guess, but also said something that made him refreshed, it felt like an initiation, Li Chromium was extremely excited: "Brother Liu, I have never heard of what you said, I have never heard of it, it is very fresh, and it is also reasonable, I am really fortunate to meet you." ”

Liu Minghua said with a smile: "Brother Li has won the award, this is just a little opinion of mine, and it is not in the eyes of Brother Li." ”

"Such a clever truth, I may not be able to hear it once in my life, Brother Liu is really a humble gentleman." Li Chrome is full of praise for Liu Minghua.

Liu Minghua shook his head with a smile and asked a very concerned question: "Brother Li, you are so concerned about these issues, and you are not afraid to give people jokes?" ”

In Liu Minghua's impression, the Tang Dynasty was still based on poetry and books, and its educational purpose was to train officials for the imperial court.

The eldest grandson Jiaqing smiled, and replied on behalf of Li Ran: "Minghua doesn't know anything, Guozijian is not as good as his place, you can ask questions and have ideas to say, even if you are wrong, you will not give people jokes." However, like Brother Li, although there are thousands of people in Guozijian, there is only one such one. Although we secretly called him crazy, we didn't mean to look down on him when we met and made fun of him, after all, this is his hobby. ”

The students echoed in unison: "Yes, Brother Eldest Sun is right. In Guozijian, he is not dedicated to poetry and books, but also can learn miscellaneous studies, as long as he is interested in things, he can also learn. ”

The highest university in the Tang Dynasty actually encouraged students to engage in "extracurricular learning", Liu Minghua couldn't imagine it, and gently high-fived and praised: "It's really rare!" Aren't you afraid of missing the future? ”

"What's the matter, Brother Liu? Are you worried about me too? Li Chrome chuckled lightly and disagreed: "As long as you don't miss your homework, it doesn't matter how much you learn miscellaneous studies." ”

The Tang Dynasty Guozijian did not stipulate death in the setting of teaching content and subjects, let alone cramming education, but had great flexibility, giving students a great degree of choice, and students could choose according to their own preferences.

The Confucian classics are divided into three categories: large, medium and small, the major classics are "The Book of Rites" and "The Spring and Autumn Zuo Chuan", the middle classics are the "Book of Songs", "Zhou Rites" and "Rituals", and the small classics are "Zhou Yi", "Shangshu", "Spring and Autumn Ram Biography", "Spring and Autumn Valley Liang Biography". Students can choose to study according to their own preferences according to the standards, if they choose the "two classics", they must be a major scripture and a middle or small scripture; If you choose the "three classics", it means that you must choose one of the large, medium and small classics; If you choose the "Five Classics", you must study all the major scriptures, and at least one of the other classics must be studied.

"The Book of Filial Piety" and "The Analects" are compulsory courses, whether it is scriptures, calligraphy, or arithmetic, as long as they are the supervisors of the country, they must be studied, nothing to say.

Giving students sufficient autonomy is not a laissez-faire, but there are very strict regulations, and there are regulations on the number of years for studying scriptures, such as one year for the Analects and the Book of Filial Piety.

At the same time, there is also a very strict assessment system and a reward and punishment system. The examinations in the Tang Dynasty were divided into ten exams, annual exams, and graduation exams. The ten-day exam is a ten-day test, which mainly tests the knowledge taught within ten days, similar to our current quiz, three points are general, two points are passed, and one point is not passed, and you will be punished. The annual examination is to assess the knowledge learned in a year, and if you learn the scriptures, you will be tested in ten articles, eight articles will be superior, six articles will be medium, and five articles will be inferior. The inferior class is a failure, and you must repeat the grade, and if you still fail the annual exam, you will be ordered to make up for it, and those who still fail will be embarrassed to drop out.

The graduation examination is made by the doctor, and the Guozi priest wine personally invigilates the examination, and those who pass the examination can take the provincial examination or the Ministry of Rites examination, and there is a chance to be lifted, once the middle lift is the "pillars of the court". If you don't want to be an official career and just want to be a scholar, those who pass can still study again, and students in four subjects can enter Taixue, and Taixue can enter Guozixue.

The management style of the Tang Dynasty Guozijian is very similar to that of modern universities, which is amazing. Of course, Liu Minghua didn't know this, and he was worried about Li Chromium in vain.

During the period of Taizong of the Tang Dynasty, great importance was attached to Confucian education, and Confucianism flourished for a while. After Gaozong and Wu Zetian, Confucianism gradually declined, and there was a situation where "students no longer take scripture as their intention", which weakened the influence of Confucianism in a certain way, and laid the foundation for the prosperity of miscellaneous studies and gewu, and it was a growing number of miscellaneous scholars.

Liu Minghua really couldn't imagine that the Tang Dynasty had such a pragmatic education, which was better than the "Eight Strands" in the Ming and Qing dynasties. The enlightened style of study has cultivated a lot of pragmatic talents, which may be an important reason why the Tang Dynasty can be strong.

I like Li Chrome from the bottom of my heart, Liu Minghua teased while sighing: "Are you not afraid of being greedy and chewing too much, and you will be a laughing stock?" ”

Li Chrome didn't care, and said with a smile: "Brother Liu doesn't know something, even if there is something inappropriate in the doctor's teaching, you can raise it, you don't have to take the doctor's words as the standard, the doctor not only does not blame, but also encourages." Those who are like me will not give people jokes, but those who know will only teach me. ”

The doctors of the Tang Dynasty were mainly responsible for teaching the knowledge of the students, equivalent to the professors of modern universities, except that they had much more influence than the professors, and they could meet with the emperor, and the emperor would summon them to discuss state affairs if necessary. It can be said that Bosheng is the authority of the Guozijian, highly respected, and they can correct the mistakes they make, so the style of study is only better than that of modern colonels, Liu Minghua once again praised it: "It's really unexpected!" ”

During the Ming and Qing dynasties, scholars attacked each other when they disagreed, saying that "the Tao is different and does not conspire with each other", and labeled the opponent as "not in line with the way of the saints" and "not respecting the words of the ancestors", and even caused party disputes and brought disaster to the country and the people. The Tang Dynasty's style of study was so good, it was impossible for Liu Minghua not to sigh.

"Brother Liu's first time, we have to take care of it, I have a lot of questions to ask you." Li Chrome is really a good student, ready to stick to Liu Minghua.

He likes natural science, it's no problem to explain it to him, but not now, Lan'er has to do it first, Liu Minghua smiled and declined: "I feel Brother Li's hospitality, but I still have important things to do, so I will leave first." ”

Next, Liu Minghua and others continued to visit Guozijian, and then Liu Minghua had a bottom in his heart. In the afternoon, Liu Minghua had to go to the gunpowder factory, so it was impossible to stay at me for too long. (To be continued......)
