'Erniang, you said that you learned the first pipa song at the beginning, and you learned it for a month, and it became a month? Li Chen asked, "That's right." Yang Er raised his head proudly.

One of them still thinks that's too inefficient. Li Chen smashed his mouth, Yang Er was about to sneer at him, and actually said that I was inefficient, "That's it, you find two, or three, three talented newcomers, as long as you know how to play." Yang Er didn't speak, and raised his eyebrows slightly.

I asked them to learn a piece in half a month. Li Chen was ashamed, and Yang Er almost jumped up when he heard it, "Okay, three of them?" It doesn't take half a month, you can teach them to play tunes within a month, and I, Yang Er, will admit defeat. ’

'Hehe, if you really train the three of them to be able to play within a month, in the future, Li Jun wants the slave family to go east, and the slave family will go east, and if the slave family wants the slave family to drive chickens, the slave family will not chase the dog. Yang Er laughed angrily, not believing that Li Chen had this ability at all.

There's no need for this, it's just that in the future, a certain family will marry Xiaohong, and ask Yang Duzhi to raise his noble hand. It sounds very tempting, a big beauty, fight with you, you win the bet, and tell you that you can lose at your disposal, this is really... (Mysterious voiceover: Do people say that?) It's all up to you. ）

'Time is a bit tight, we're running out of time. I'll go back and get ready, and you can wait for them to go to my place by themselves, right?" Don't think too much, otherwise it won't be easy to explain to Xiaohong at that time.

'You have something to do with Xiaohong, the slave family is happy to see it, don't worry about Xiaohong's identity, although she was adopted by the Yang family since childhood, the family has never regarded her as a subordinate. It's just that in the future, please ask Li Jun to treat Xiaohong well, don't make Xiaohong sad. Seeing that Li Chen was leaving, Yang Er said, this is the first time that Yang Er has mentioned Xiaohong's matter to him after knowing him for so long.

Also, Xiaohong Nan Nizi was a little unavoidable, always thinking that her status was humble, and asked Li Jun to enlighten her more. She always regarded herself as a slave and sold herself to the Yang family. Li Chen turned around in surprise, it turned out that Xiaohong was worried about this.

In fact, it's not that Xiaohong thinks too much, it's that Li Chen hasn't thought about this problem. In modern society, if you want to say that everyone is equal, that children will believe it, and even children will not think so.

Then the same kindergarten, and then there will be 369 and others, and when they enter the national elementary school, the same problem is happening again, and when they get to the middle school, no one believes in the eight achievements.

It's just that modern people probably don't think about the problem of what slaves and maids can't marry with their beloved, and the great thing is that the door is not right. But even if the door is not right, many people still want to squeeze up and enter the wealthy family.

But for the Tang people, and even the ancients, this is a very serious identity problem. In ancient times, slaves and maids were property, goods. Even if it seems to be more enlightened in the Song Dynasty, I am afraid that it is almost the same, and the habits and human nature that have been obtained for thousands of years cannot be reversed by a piece of law.

Volume 20 of the "Tang Law Shu Yi" "The Law of Thieves" contains: "Slaves and maids and livestock are all the same property. Volume 17 "The Law of Thieves" said: "Slaves and maids are the same as wealth, so there is no other thing." There are many such provisions in Tang Law.

The same is true for slaves and maids to get married, the same kind is married, and the status is passed down from generation to generation. Slaves and maids can only marry slaves and maids, and the children born are also slaves. If an ordinary person wants to marry a slave or a maidservant, it is to be punished.

Volume 14 of the "Tang Law Shu Yi" "Household Marriage Law" contains: "Those who marry a good man with a slave as a wife, one and a half years in prison, the female family is reduced by one class, and the same is true for those who marry themselves, and those who know the master know it, and the rod is one hundred, so the person who is registered as a servant will flow three thousand miles. ”

If a male slave marries a child of an ordinary good family, he is sentenced to imprisonment, and the woman is also worthy of a sentence. Then if the master knows, even the master will be sentenced to a hundred sentences, which can kill people. What's more important is that if a slave or maid marries a good man, and the good man becomes a slave or maid, he will be exiled for 3,000 miles.

'Even if you are a slave, you can be a concubine, can you?' Li Chenhun said indifferently, "I don't marry a wife, I can only marry him as a concubine." I thought of him as a wife. ’

"Are you a student from the Japanese country, you don't even understand this. Yang Er rolled his eyes, "The household marriage law stipulates that slaves and maids cannot even be concubines, unless the slaves and maids have children and are regarded as lovers, they can be concubines." Li Chen was embarrassed, he really didn't know. He never thought of this problem, and subconsciously thought that a slave or maid could be a concubine if she could not be a wife.

even thought that concubine = a slave who had a husband and wife relationship... Meow, don't all those TV series act like this? There are also historical novels, isn't it the same, it turns out that it doesn't work.

'It's the same as the kids you adopted. It's just that she can't see it herself. In the future, I hope that Li Jun will have more pity. 'I'll have it, don't worry.' After that, he waved his hand and left, and before leaving, he took Yang Erde's score with his hand, saying that he wanted to refer to it, Yang Er smiled and let him take the score.

'It's a god thing. Li Chen looked at the score while walking, "Is this a password?" Yanle is also a half-word score, and it is really a half-word. ’

Li Chen has this music score in his hand, and he doesn't know that people will think that this is a code book. I saw a booklet, the whole text is strange words, look closely, you can see that it is probably the side of the Chinese characters, Li Chen looked carefully, it seems to be a bit like the Japanese Katakana.

This is a musical score used by the court in the Tang Dynasty, called Yanle half-character score, but there is no such name now, and it will not be until after the Song Dynasty. In modern times, it is commonly known as the subtractive character notation, which is the famous pianist Cao Rou in the Tang Dynasty, based on the text notation of the previous generation, invented the subtractive character notation.

The use of kanji to the side to record, does it sound familiar, yes, it is katakana. If you look closely at this subtractive notation, there are many characters similar to Japanese. It is estimated that the Japanese got the katakana at the beginning, and it was also created based on the subtractive character spectrum.

'Alas, Chinese, I have no imagination at all. Looking at this score, Li Chen sighed again, and every time he watched it, he sighed once. How can we think of using rigid words to record the way of talking, for thousands of years, the pragmatic Chinese have not thought of a relatively simple way.

The Chinese are pragmatic and do not engage in hypocrisy. But a lot of the time, it takes some imagination. Let's take the sheet music, but no one in China has thought of using something more abstract and imagining a more convenient way to record the score.

I just want to get it, and use clumsy words to describe ethereal music. Even if the minus notation is invented, how can the notation of the text be as good as the stave.

Like that mathematics, the Chinese are also clumsy. It will only be described with words, and it is clear who is more convenient to describe it with drawings and some abstract symbols. Western-style mathematics is both easy to learn and easy to think. Chinese mathematics, just looking at the text description makes you dizzy.

Therefore, the Chinese cannot produce Einstein, nor can they produce Hawking. Too pragmatic, lacking imagination, without seeing things with your own eyes, you can't do it, and you won't find out. Modern science is no longer the kind of research that used to produce results.

Many scientific developments are based on theoretical utopia, and then gradually confirmed. Like the theory of relativity, it was also considered utopian at the beginning, but later many phenomena were discovered step by step, which coincided with the theory. Chinese don't go to black holes, it's too abstract.

Many scientists, like Stephen Hawking, summarize various phenomena, add their imagination, put forward one hypothesis after another, and then disprove or confirm step by step. to get evidence that black holes do exist.

'Let's do this for now.' Li Chen found that he was thinking too much and thinking too far. Maybe Chinese science and technology have developed to a certain extent, and there will be such people. Induction, summarization, and hypothesis guide future generations to move forward towards a broad road. The premise is that China does not fall into the cycle of chaos again.

'I came back, and I didn't have to go to class. Li Chen put aside his thoughts and pushed open the door, "Master, you are back." As soon as he opened the door, a servant came up to serve him.

Last time I was sick, I thought about buying someone to serve, and when he recovered, he didn't forget about it, so he really bought it. There are more than 10 people in the family, and everything is done by themselves, which is too much trouble.

'Uncle, you're back. A few children ran downstairs, "Are you serious about studying, wait a minute, Uncle will check it." ''Yes, I have. ''I have it too.'' ’，

'Uncle, just now the shoe shop sent you the boots you ordered. Wait until a few newly recruited children have finished chattering, and Ah Xiang, who is a little calmer, said this.

'Come, here you go. After finishing speaking, Ah Xiang gave the things to Li Chen as if offering a treasure, "It's noisy downstairs, what kind of system." At this time, in a room on the second floor, there was a dissatisfied voice, it was Wang Xianyan, he was still teaching Xiaohu a few people, but he was interrupted by the noise downstairs.

'Poor sour, I told you, you have to combine work and rest, and every time you go to class, it will be endless. Li Chen was not to be outdone.

Based on modern habits, Li Chen set a fixed time for each class, and then timed it with an hourglass. It's just that every time Wang Xianyan gets a class, he will take more than that, he didn't refer to the hourglass at all, and then he thought about it, since he taught the child, of course, he had to take a little more, where was there a provision for the time of each class.

But Li Chen, who came from modern times, knows that the length of each class is learned. Elementary school has the shortest class time, a little more in junior high school, and longer in high school, and the university is basically the same as high school.

Because people's attention span is limited, it is a peak. The class time, just enough to make the students' attention, increase from the bottom to the high, and finally back to the beginning. Insert a break in between, just enough for students to rest and prepare for the next class. Like Wang Xianyan, he will think about increasing time, and no matter how efficient it is, Li Chen has always disdained it.

'Uncle, what do you have to do with these leather boots, why are they so short, and there are iron plates nailed under the soles?, how inconvenient it is to wear like this. Seeing that Li Chen and Wang Xianyan had a round of verbal battles over class time, Ah Xiang took the opportunity to interject and ask.
