Weird Three Kingdoms

Chapter 19 Named Disciple
A few days later, Fei Qian never expected that Li Ru would recommend him to Cai Yong.

Speaking of Cai Yong, he is really a genius among literati. Just the halo hanging on his body can blind the eyes of ordinary people.

Great Eastern Han writers, great historians, great musicians, great painters, great calligraphers, and so many of them came down and really doubted whether Cai Yong was a normal human being.

In terms of literature, Cai Yong is most famous for leaving behind the "Xiping Shijing".

When the fashion was in the period of Emperor Ling, Cai Yong believed that in some of the Confucian scriptures at that time, there were many punctuation and attachments, and there were many errors in the words.After the edict was approved, Cai Yong personally wrote the elixir on the stele and ordered it to be engraved. It stood outside the Taixue Gate. There were 46 inscriptions on the stele. All the scholars from all over the world edited the text template. For a while, the gate of Taixue was very lively. Many people came here to watch and write every day. There were thousands of cars and horses, and the roads were blocked.

In addition, in terms of music, in addition to the story of Jiaoweiqin, which is talked about with great interest, Cai Yong also formulated Cai's five lanes, "You Chun", "Lushui", "Whispering", "Sitting Sorrow", "Qiu Si" ", and later, together with another musician Ji Kang's custom-made Ji's four lanes, namely "Changqing", "Short Qing", "Long Side" and "Short Side", they were called Qinqu Jiu Lane, and even became the royal family after the Han Dynasty. One of the evaluation criteria for admission.

Of course, later generations' interest in Cai Yong also came from his daughters, Cai Yan and Cai Zhaoji, so I won't say much about this.

So when Li Ru informed Fei Qian that he had recommended him to Cai Yong, Fei Qian really couldn't believe it, until he entered Cai's mansion, there was still some trance in his dream.

Cai Yong sat in the first place, and some did not know how to deal with it.Cai Yong has not accepted disciples for many years. First, his reputation is growing, so he must be cautious about accepting disciples. Second, the rubbish things that his daughter encountered really made him feel a little sad. Third, his age As he got older, he really didn't have the energy to teach with all his heart, so he closed the door and stopped accepting disciples, but now I don't know where Li Ru went to find the token he gave to his friends before, and he was sent back, the condition is to accept Feiqian As a disciple, this is really embarrassing for Cai Yong.

When Li Ru sent the token, of course he said it casually and very clearly. He clearly explained that Fei Qian's father had been kind to him. I found Cai Yong's token, and asked Cai Yong to decide whether to accept it or not. Anyway, he has a clear conscience in what he should do.

The most important thing is this sentence "with a clear conscience", you Li Ru have a clear conscience, if I, Cai Yong, refused, then I said "hold this thing, do what I can, and let me do anything", wouldn't I be hitting myself? How can I have a "clear conscience", and it is rumored that I, Cai Yong, have reneged on my promise, so do I still want to be a human being?
Cai Yong looked at the young people in the hall. They were slender, introverted, and handsome in appearance. He was a little shy, but whether he accepted it or not, he felt a little heartbroken. Find out, ask first.

"What do you teach?" - What have you learned and what are you good at?

"The boy has a rough understanding of the six classics, and prefers to calculate the classics." Thanks to Fei Qian's previous blessing, most of the six classics still remember some, but Fei Qian can't do it if he wants to say something small and righteous, but the calculation of the classics is different. Just kidding, later generations are also people who went to high school and college. No matter how good you are from the Eastern Han Dynasty, have you seen matrices, whether you know calculus or not, and the overall study of probability theory...

In fact, Fei Qian wanted to say, not only that, but I also know how to order "washing in the gutter", as well as "Biyanet" and "Amei Dad", but unfortunately these things are completely useless in the Eastern Han Dynasty...

Cai Yong was quite surprised, because arithmetic was one of the most cutting-edge knowledge in the Eastern Han Dynasty, and it was not something ordinary people could play.At this time, "Zhou Bi Suan Jing" was only two or 300 years old, and the articles were so obscure that those without strong imagination and deduction ability would be blind even if they read the text. For example, there is such a description in "Zhou Bi Suan Jing", "If Those who seek the evil solstice, use the lower sun as the tick, and the higher sun as the stock, multiply each of the Pythagorean shares, and divide them with a formula to get rid of the evil solstice." This is the Pythagorean theorem. If you don't understand it, then Calculus has nothing to do with you.

There is another book that is relatively good, but only a little bit better. It is the famous "Nine Chapters of Arithmetic", but at this time, "Nine Chapters of Arithmetic" has not been sorted out and annotated by Liu Hui, and it is still very messy and disorderly. Although it is closer to some specific problems in life, it still belongs to the kind of books that are not approachable.

Cai Yong suddenly became a little interested. After all, there are relatively few people who study this stuff in this era, and it is hard to find a fellow, so he casually came up with a question in Chapter Nine to try: "Today, there is a city that does not know its size. Go out of the North Gate There is wood at twenty paces, turn off at fourteen paces from the south gate and walk westward at 770 and five paces to see the wood, how about the town?" ——translation means there is a small square town, and there is a marker 20 paces out of the north gate Big tree, and then 14 steps out of the south gate and 1775 steps westward before seeing the big tree as a landmark. Find the area of ​​this small square town.

Although the topic is short, it involves a lot of things. In addition to basic number operations, the most important thing is to know the theorem of similar triangles, and to know how to solve the two-dimensional linear equation. It is a moderately difficult topic in the nine chapters of arithmetic. Now, Cai Yong also took it out at will to try it out to see if Fei Qian really understood the classics of arithmetic.

But this question of middle school student difficulty was not a problem for Fei Qian at all. He asked Cai Yong for a pen and paper, drew a picture, listed an equation, and calculated the answer directly.

Cai Yong stretched his neck and looked at it. This picture can probably be guessed as a schematic diagram, so what are the ghost symbols ABCD1234 on the picture?Immediately, my heart was itching, but I felt a little embarrassed to ask.

Fei Qian had the intention to show off the 30-yuan math problem that was deceitful in later generations, but let's forget it. After all, the 30-yuan hotel question itself is a bit misleading. If Chong Daru is seen through by others, will it be extended from the title to the person, then it will not be fun, or if a "sly" name is left behind, this life will basically be ruined.

So let's pretend to be honest, everyone likes honest people, right?

After Fei Qian finished his calculations, he stood with his hands down and looked like a good student.

Cai Yong weighed it carefully, hesitated again and again, affirmed Fei Qian's knowledge of arithmetic, and finally said: "Well, let's take you as a named disciple, every third day of junior high school, every twelve years can go to Taixue to listen to my lectures; Fifth, if you have any questions on the twentieth day, you can ask here, how about it?" The named disciples are also considered disciples, and they are not considered to have violated their previous promises. The problem-solving paper asked my baby daughter if she could understand it.

　The 30-yuan math question is nothing but that misleading sentence. In ancient times, once this kind of cleverness was seen through, its reputation would be ruined, and it was in front of a big man.Newcomers have all kinds of requests, and the collection is recommended for some motivation.
