Su Jing chose wood as the material for the frame because she had all the tools to make the pulley.
Su Jing took her things and came to the yard.
"Come on, Lao Liu, let me measure the distance between your eyes."
Su Jing took the ruler and drew it directly in front of Liu Bowen's eyes.
Liu Bowen was also quite cooperative:
"Sorry, Mr. Su."
Su Jing smiled and said: "It's just a small matter, it's just a coincidence. I don't have anything to do anyway."
In this way, Su Jing was making the frame, while Liu Bowen listened to Zhu Biao's explanation of the propagation of light.
"The spread of light"
Zhu Biao was a little excited to teach Liu Bowen, after all, Liu Bowen was his teacher before.
But when he started talking, the tension disappeared.
Liu Bowen listened very seriously and did not have any contempt in his heart.
As an all-rounder who is proficient in astronomy, geography, arithmetic, etc., Liu Bowen is always willing to accept new knowledge.
When Zhu Biao explained, he also used several small experiments that Su Jing had done for him before.
An hour later, a polished glasses frame was completed.
The appearance is very simple and simple, but the eyes are the main function.
Su Jing pressed the lens on and carefully checked it several times to ensure that the lens would not fall off easily, and then she felt relieved.
"That's probably the principle. This is why glasses can help you, Master Liu, see clearly again."
Zhu Biao let out a breath and finally finished explaining.
Liu Bowen nodded, his heart was shocked, and he cupped his hands towards Zhu Biao and said, "Thank you, Master, for clearing up my doubts."
Zhu Biao immediately said: "Master Su taught me these."
"Old Liu, come and try it on. Do these glasses fit you?"
Su Jing handed the finished glasses to Liu Bowen.
"good."
Liu Bowen took the glasses and took a look at them, then he understood how to wear them.
This image is relatively easy to understand.
"very suitable!"
As soon as Liu Bowen took it on, he found that his eyes suddenly became clear, and all the previous fuzzy feelings disappeared.
It's like opening up a whole new world.
Liu Bowen was a little excited. He couldn't remember how many years it had been.
When did I start not being able to see clearly?
In my early years, it was common for me to stay up all night and study for the imperial examination.
According to Zhu Biao's explanation, it should be that the eyes were overused at that time, which caused irreversible changes in the eyes.
I never thought that at this age, I would still have such a day.
Liu Bowen was extremely excited in his heart.
He looked at Su Jing, bowed to Su Jing and said, "Young Master Su has been so kind to you, but I can't repay you for it."
Eyes are the window to understand the world, so the importance can be imagined.
Su Jing said with a straight face: "Old Liu, what are you doing? There's no need to do this. It's just a gadget."
"Take care of your eyes at all times. I'll take it back and teach you some eye exercises."
Su Jing has always been very generous to people with appetites.
He didn't regard this kind of thing as a favor.
Liu Bowen looked at Su Jing and felt even more guilty. He had harmed Su Jing!
The two of them returned to the living room. After all, Zhu Biao and Zhu Ru still had to study in the yard, so chatting nearby would easily disturb them.
"Come on, Lao Liu, I'm here to teach you eye exercises."
Su Jing has already begun to demonstrate to Liu Bowen.
"The first section, rub Tianying point..."
"In the second section, squeeze the Jingming point..."
"In the third section, massage the Sibai acupoint..."
"In the fourth quarter, press the temples and scrape the eye sockets..."
Watching Su Jing's demonstration and explanation, Liu Bowen quickly learned this set of eye exercises.
"Remember to do it twice a day from now on, once in the morning and once in the afternoon. Eye protection is not something that can be achieved overnight. You have to persist."
Su Jing asked Liu Bowen.
Liu Bowen nodded: "I understand. Thank you Mr. Su for giving me glasses and teaching me this set of eye exercises."
Whether it was glasses or eye exercises, Liu Bowen felt Su Jing's sincerity.
At this moment, Liu Bowen didn't even dare to look at Su Jing.
"Old Liu, you, you, I've let you do whatever you want, why can't you let go?"
Su Jing said helplessly.
Since Liu Bowen came here, his body has never been completely relaxed and has been in a tense state.
It can only be said that Liu Bowen has always had something on his mind.
Liu Bowen paused and said, "Mr. Su, I still have some questions that I want to ask you. I don't know if I can answer them."
This time, Liu Bowen came with the purpose of asking for advice, so naturally he would not miss this opportunity.
"Of course, but my knowledge may not be as great as you think, and you may be disappointed."
Su Jing said lightly.
Living in the Ming Dynasty, the more Su Jing knew, the less superior he felt as a modern person.
The wisdom of the ancients cannot be underestimated.
Liu Bowen didn't take it seriously and thought Su Jing was being modest.
He hesitated for a while and said: "Master Su, when I was at the master's house, I read what Master Su said about the fate of the feudal dynasty. I have been immersed in it since then and cannot extricate myself."
"Master Su once said that feudal society would eventually perish. So what will happen to the world after feudal society?"
What Liu Bowen is most curious about is what kind of new era will usher in after the reincarnation of the feudal dynasty is shattered.
Maybe he would never be able to see it, but at least he wanted to know what kind of world it was.
Su Jing was also shocked when she heard this.
Did everything he talked about with Zhu Biao reach Old Liu's ears?
Is this Zhu Yuanzhang a little too bold?
Su Jing was not surprised that Zhu Yuanzhang knew what she and Zhu Biao had said.
After all, they are still father and son, and their relationship must be closer than that of master and disciple.
But isn't the old Liu in front of him a servant of his apprentice's family?
Although his status is relatively high, he is definitely not considered his disciple's family.
Su Jing still knew a little bit about the nature of what she was talking about.
The feudal dynasty will surely fall, and that means the Ming Dynasty will also perish.
If this spreads out, it will be a major crime to punish the Nine Clan!
However, I am alone here and there are no nine clans to kill.
Although Old Liu had heard some disrespectful content before, Su Jing was still surprised.
this.
Obviously, Su Jing was really shocked.
"Old Liu, do you have such a good relationship with your father?"
Su Jing did not answer Liu Bowen's question, but asked instead.
Ordinary masters and servants should not be able to do this.
Otherwise, this is a problem.
If Liu Bowen came to the rescue and spread the news, Zhu Yuanzhang would be the unlucky one.
Of course, Su Jing didn't know their identities, so it was normal to have doubts.
Hearing Su Jing's question, Liu Bowen's expression was slightly strange.
How good is your relationship with Zhu Yuanzhang?
Is it good or bad?
Before the Ming Dynasty was established, Liu Bowen could say with great confidence that his relationship with Zhu Yuanzhang was that of Liu Bang and Zhang Liang.
Very good.
But now, in my heart, I still want to continue to serve Ming Dynasty and Zhu Yuanzhang.
However, he only ended up under house arrest.
"It's not bad."
Liu Bowen replied.
Um?
It's ok?
Su Jing frowned, not quite believing Liu Bowen's words.
This is not an ordinary relationship. Can one talk nonsense about the demise of the feudal dynasty?
"Master Su, everything I said is true and I am absolutely not deceiving you."
Liu Bowen felt Su Jing's gaze and said immediately.
Apart from having to conceal his identity, Liu Bowen did not want to deceive Su Jing into anything.
"Forget it, I don't want to think about it anymore. Anyway, this is your business, and you don't know much about it."
Su Jing shook her head and stopped thinking.
"Thank you Mr. Su for your understanding."
Liu Bowen said.
He was really worried that Su Jing would get to the bottom of it, and he would continue to hide his conscience.
But it’s impossible not to hide it.
Su Jing paused and said, "You are asking about what kind of social form we will enter after the end of feudal society, right?"
"Yes, Mr. Su, please clarify my doubts."
Liu Bowen replied seriously.
Liu Bowen has a high IQ, deep knowledge, and broad vision, so he can understand more from Su Jing's remarks than others.
Liu Bowen really wants to know about the changes in social form and what the future will look like.
Su Jing also felt Liu Bowen's emotions. He straightened his body and was frantically recalling relevant knowledge in his mind.
The old Liu in front of him is not Zhu Biao. He is sincerely seeking knowledge, pure knowledge.
"Old Liu, I don't know much about some things, so what I can tell you is only what I know and understand, which may not be correct."
Su Jing laid the groundwork first.
After all, you can't do anything to mislead others.
Liu Bowen nodded and said, "Master Su, just say it, I understand."
Su Jing's eyes moved slightly, she pressed her right hand lightly on the table with her index finger, and then said:
“If you want to know the social form after feudal society, you must understand the previous social form.”
"Through historical changes and finding the changes and patterns, it is possible to understand the future situation."
It would be too fake to talk directly to Liu Bowen about the future.
Su Jing still thinks it is better to proceed step by step.
"What Mr. Su said is true, but I don't know what the social form was like before this?"
Liu Bowen nodded in agreement.
He was not in a hurry, but wanted to be patient and listen to what was going on.
It took him a long time to understand the term feudal society before he had a little understanding of it.
Su Jing looked at Liu Bowen and said, "Let's start with the current social system. I call the current social form feudal society."
“The social form in which feudal land ownership is the dominant system and the landlord class dominates other classes is the essence of feudal society.”
"This is not just the case in our Ming Dynasty, but also in other distant countries."
“By controlling land, the means of production, the landlord class exploits other classes through means such as extracting land rent and lending usury from the farmers who use the land.”
"At the same time, the forms of feudal land ownership are also different. It can be realized through contract leasing, paying land rent, hiring tenants, etc., but its essence is still a relationship of exploitation and exploitation, which will not change the nature of feudal society as a class society. Nature."
"So, Lao Liu, from what angle do you think the word feudal should be understood?"
Su Jing asked a question while he was sorting out his thoughts in his mind.
When it comes to the theory of feudal society, Su Jing learned about it from Marxist history.
In fact, it mainly applies to Europe. For China, Su Jing needs to add her own understanding.
This is also an important reason why Su Jing specifically told Liu Bowen that these were only his personal understandings before starting his lecture, and were not necessarily correct.
China cannot be explained entirely by this set of theories.
Liu Bowen frowned and thought seriously about Su Jing's question.
After a while, he replied: "I thought feudalism should refer to the land enfeoffment system."
really.
Su Jing was not surprised by Liu Bowen's answer. After all, feudalism has existed in China since ancient times, so it is normal to understand it this way.
"What about the Qin Dynasty, Old Liu, do you think the Qin Dynasty was a feudal society?"
Su Jing asked Liu Bowen.
Qin Dynasty?
Liu Bowen was stunned, and then he remembered what Su Jing once said: After the unification of the Qin Dynasty, it was the beginning of feudal society.
However, the Qin Dynasty did not implement the feudal system, but used the prefecture and county system.
"Then how should we understand feudalism?"
Liu Bowen said humbly.
He has discovered his own fallacy, and this understanding is problematic.
Su Jing replied: "What about changing the perspective and understanding it from the perspective of production relations?"
"The relations of production between the landowning class and the common people."
Relations of production?
Liu Bowen was stunned for a moment and thought carefully for a while.
The essence of feudal society should actually be understood from the perspective of production relations.
"Master Su, are you saying that the exploitation of the common class by the landlord class constitutes a feudal society?"
Liu Bowen asked Su Jing.
sharp!
Although the words were very vague, Liu Bowen's words had already surprised Su Jing.
Lao Liu has never studied Marxism, but he can understand this.
Pretty good.
Su Jing nodded and said: "Old Liu, although your understanding is not completely accurate, it is pretty much the same."
"Our feudal society has four basic characteristics."
"First, economically, private land ownership dominates. Second, politically and culturally, a highly centralized autocratic system is implemented."
"Third, in terms of culture, Confucianism is the core. Fourth, in terms of social structure, it is a patriarchal hierarchy that combines family power and political power."
"Economic, political, cultural and social structures are the basic elements that constitute a society."
Liu Bowen carefully tasted what Su Jing said, and it was constantly reflected in his mind.
Su Jing was not in a hurry and just sat there, letting Liu Bowen think patiently.
These cannot be understood by just listening, they must be understood!
Fortunately, Liu Bowen was not a fool. He quickly matched what he saw and heard with these four characteristics.
"Master Su, I understand a little bit."
After about a stick of incense, Liu Bowen looked at Su Jing and said.
His eyes were full of desire, and what Su Jing said was a revelation to him.
In his opinion, Su Jing was like a being on the vast river of history, who could fully explain the world he lived in in just a few words.
Su Jing is truly extraordinary!
