Now send the exam papers back. If you make a mistake, remember to correct it yourself, write the answer and return it. Li Chen didn't let these children divert their attention and said that he wanted to take the exam, in fact, he really took the exam.

"Big head, you're really good at getting 80 points. Ergou looked at the roll in distress, and then looked at the big head to get the roll. This exam paper is similar to the modern exam paper, the small difference is that these papers are all handwritten, and Li Chen has to copy them one by one, but fortunately, there are only seven of them, and they are mathematics. That is, there are only seven sheets, and he will copy them by hand, otherwise he would have found a way to print them a long time ago.

Then, these exam papers should be recycled, and the back side can also be used at that time. No way, Tang Dynasty paper is expensive...

'Eighty points is still a few wrong questions, stupid babies are amazing. 100 percent. ''He's just good at math, not so bad.'' Uncle seems to be planning to teach him more difficult math problems. ’

This class was a math exam, and in terms of progress, Li Chen taught them to learn in a unified manner, anyway, they didn't have any foundation before. He didn't have time to distinguish their learning ability according to their age, so he could only teach them from simple to deep.

The focus is on the content of the teaching, Li Chen taught them to use Arabic numerals and various modern addition, subtraction, multiplication and division symbols, which once surprised Wang Xianyan and called Li Chen a genius. Without him, the description of mathematics in ancient China was too complicated, and after Li Chen's simplification, the equation would not have to be long.

If you've ever read the master's math textbook, you'll be dizzy to death. Because the whole text is described. Li Chen admired the ancients very much, and no one thought about how to simplify mathematics and replace complex and cumbersome words with simple symbols. It is better to use complicated words to describe it than to make people dizzy.

(Quite unexpectedly, the silly baby said that he was stupid, not stupid at all.) In the process of learning mathematics, what surprised Li Chen was that he was a stupid baby. This usually stupid-looking kid is unexpectedly sensitive to mathematics, which makes Li Chen, who was not assigned to a class, consider whether to teach him something more in-depth.

(He should count on the Asperger's.) ), Asperger's. Li Chen is not a medical student, so he does not know the detailed symptoms of this symptom.

In his impression, Ryasberg is also called autism. These people have social impairments, ranging in severity and manifestation. However, the common denominator is that they are usually particularly sensitive in a certain aspect, and if they lose the east, they will reap the mulberry elm. This kind of person usually has a talent that surpasses ordinary people in a certain aspect. Li Chen felt that the stupid baby should be this kind of person.

In modern times, everyone is more familiar with people, such as the founder of Facebook, or the founder of Microsoft, which is actually a representative of this kind. It's funny to say that people who are not good at socializing have created the most social software used by the most people in the world.

'Little Tiger Little Tiger, what have you been doing?' That's the big head. 'It's good that you didn't have an exam yesterday. ', this is the second dog...'Okay, Uncle said he made up the exam today. It's a fat ball.

The next day, Xiaohu returned. As soon as I came back, I was surrounded by children, babbling about something, and in the end, they were all asking, what did Uncle tell you to do.

You'll find out in a few days. Although Li Chen didn't say anything about secrecy, Xiaohu knew the importance of this matter. In other words, he is funny, but he refuses to say it. No matter how many other children asked, they refused to say anything, but only said that you would know in a few days.

'Neutralization Festival? Li Chen asked in surprise, "You don't even know about the Neutralization Festival?" Xiaohong was surprised. Xiaohu came back, he entered the door with his front foot, and Xiaohong on his back foot also happened to come to him. said that he wrote the lyrics, and the second lady wanted to sing at the banquet on the neutralization festival. Li Chen asked, what is the Neutralization Festival.

The Neutralization Festival, in fact, did not appear for a long time in the Tang Dynasty. It was probably proposed by Li Mi during the Dezong period a few decades ago, on February 1. Why is this day set, one of them: February 2 is the day when the dragon raises its head in the lunar calendar, the dragon manages the rain, and the second day of February is the beginning of the harmony of yin and yang under the rain.

Second, Li Mi postponed the holiday at the end of the first month of the lunar calendar, and merged it into the second day of February. After the Shangyuan Festival on the sixteenth day of the first month of the Tang Dynasty, there was no holiday, followed by the third day of March. Therefore, the thirtieth day is set as a holiday, and on this day the emperor will give a banquet, put up lanterns, and the monarchs and ministers will enjoy together.

According to the record of "Tang Hui Yao", in the first month of the fifth year of Zhenyuan (789 AD), Dezong issued an edict to take February 1 as the neutralization festival, and the internal and external lawsuits were off for one day. And ordered the civil and military officials to enter the agricultural book on this day, and the farmers to sacrifice grain seeds, and the princes and nobles put on spring clothes, the people and the people gave each other rulers and knives, the village community made a neutralization wine, sacrificed to the god of Goumang in the five gods, gathered and feasted, and this was called Goumang, praying for the New Year's Valley.

'Ruler and knife? Li Chen wondered, "Why? 'Why?' Xiaohong thought about it for a long time, and tried hard to figure out why Emperor Lao Tzu stipulated that everyone should give each other rulers and knives on this day, "Why did you give knives, I can't remember." I think about it a little more now. It seems that there has been such a practice for a long time, since the beginning of the dynasty. Since the beginning of the Tang Dynasty? Li Chen was surprised, this was not mentioned in history textbooks.

In the calendar, this day and night are exactly equal, and the ancients regarded this day as a day of harmony between yin and yang. It is recorded in the Book of Rites that in the second month of mid-spring, "the day and night are the same as the measure, the balance stone, the gladiatorial fight, and the right to be overlooked". Originally, it was possible to measure it by this day.

By the time of Taizong of the Tang Dynasty, Kong Yingda clearly pointed out that this school in the middle of February was properly implemented by Renjun, so that it had credibility: "Ping, when the equal, is said to be balanced in measurement, etc., and the use of people should be equal." When the day and night are divided, the king is equal, and this thing is equal. ”

Speaking of this weights and measures, that is the ruler, the imagination of the ancients is also very powerful, from the length of a day can actually lead to a bunch of big truths.

is really knowledgeable, Li Chen applauded when he heard it, he didn't know this. Xiaohong was originally a little shy, and said modestly, these are all from Yang Niangzi, and then she came to her senses and said angrily, "I didn't want to talk to you about this today..., how could I talk about the origin of the Neutralization Festival with you, who has never even heard of the Neutralization Festival." It's not strange, isn't it just a crooked building

I'm curious. What's in the crooked building, it's rare for Xiaohong to come to him by herself today, although she came over because Yang Erniang had something to find him, but Li Chen was all proud of Xiaohong. In that case, of course, we should take the opportunity to talk more.

'It's rare for you to come over and see my newly rented liquor shop.' In a few days, it will be decorated and ready to open. Bypassing the topic of the Neutralization Festival, Li Chen wanted to invite Xiaohong to his new store to take a look, "Next time, I have something to do with you, did you write the first Yuan Eve?" When Xiaohong spoke, her face looked to the side unnaturally.

Well, when I came back, I felt something, so I wrote that poem. Well, it's not bad. This question is really hard to answer, saying that I wrote it myself, it seems to be a little weak-hearted. But if it is said that Xin Qiji wrote it, how should he explain it? I can only admit it.

'Don't be strong, I don't know who you write, how can people use snow willow gold wisps. Xiaohong was shy, turned her face and said, (Maybe, I'm really writing about someone else.) Li Chen was so poor that he wanted to say this, seeing that you were still arrogant, but he swallowed it back, in case it was self-defeating, Xiaohong misunderstood that he really wrote it to others, then he really owed it.

If you like it, I can write you more. In the future, we often go out together, so I'll be more inspired. The big tail behind Li Chen shook his way, like taking a lollipop to a little girl, and then taking them to see the strange uncle of Jinyu.

Well? Actually, it seems to be about the same, but the lollipop is replaced by poetry. He is going to abduct people with some of the poems he remembers in later generations, and Xiaohong's age seems to be less than half of his physical age, if he gets married earlier, his daughter may be as old as Xiaohong, and it is not wrong to say that he is a strange uncle.

'Who's going to go out with you again, stinky.' I like this word, I have to be the second mother of our family. Xiaohong wrinkled her nose and grimaced, "Since you wrote it, what about the tune?" What tune should this word go with? ’

It's over, how do you say that? Ancient poems, whether they are Yuefu in the Han Dynasty, or poems in the Tang Dynasty, or words in the Song Dynasty, can all be sung. Or rather, it was pop music at all.

Then the problem came, Li Chen didn't understand it at all. The Qingyu case is a word card that tells people which tunes they should use to sing. Yuan Xi is the name. The Tang Dynasty shouldn't have the tune of the Qingyu case...

I didn't think about that. Li Chen could only talk nonsense, "I'm not familiar with those, I just dared to make a statement after I went back that day, and I didn't think of a good tone at all." Li Chen was covered in cold sweat, how could there be such trouble, "By the way, since Erniang wants to sing this, then trouble Erniang to compose a tune." See if you use ready-made or use Erniang to create a song by yourself. ’

'It's not so easy, it's so easy to write a new tune. The little red fox looked at Li Chen suspiciously.

How can it not be easy, modern pop songs have to be written by those creators, that is not to write well from the tune to the lyrics.

Li Chen couldn't help but think that when future generations learn poetry, they will have to learn what rhyme and what kind of rhyme they have to analyze. It's putting the cart before the horse. The ancients learned to write poetry, who will tell you about peace. There are often famous works by such and such poets, and that part is not mediocre.

Why don't people talk about it? Because people fill in the blanks according to a certain tune. It's good to read it smoothly. If you read it smoothly, it will be smooth naturally. It's like if you change the lyrics of a certain song, sing it by yourself, and fill in the content by yourself, which is not the same as what you don't pay attention to. You think it's good to sing smoothly.

But this is also something that can't be helped, the ancients have lost all the word cards. I can't help it if I want to recover. Later generations can only analyze and then imitate through this method.

'Haha, I think Erniang should have a way to get it. Li Chen, the future thief in the literary world, took Xiaohong's suspicious gaze and took her hand first, "Let's go and see my shop first." It's going to open soon, and I'll be able to get it in a few days. ’

I'll go back and tell the lady first, although the lady is already looking for the right tune, but she still hopes to find the most suitable tune from the original author, and now since there is none, I want to go back and talk to the lady first. Another day, your wine shop is open, and she will definitely go there. ’

'Okay then. I'll invite you over in a few days. Li Chen was a little disappointed, and suddenly he remembered something. 'You said that you have to have a banquet in a few days, and Mrs. Yang will participate? ''Yes.'' ''Who are they?'' ', 'Envoys, there are some local virtuous people.' Xiaohong reported a few names, either important official positions, or some celebrities.

'My poems can be sung by Yang Erniang, but please also ask Erniang to help me, okay. Li Chen's eyes lit up and he said.
