A few days later, Fei Qian really didn't expect that Li Ru would recommend it to Cai Yong. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Speaking of Cai Yonglai, he is really a bull among the literati, just the halo hanging on his body, any one can blind the eyes of ordinary people.

The great writers, historians, musicians, painters, and calligraphers of the Eastern Han Dynasty really doubt whether Cai Yong is a normal human being.

In terms of literature, Cai Yong is most famous for leaving the "Xiping Stone Classic" to future generations.

At that time, in the period of Emperor Ling, Cai Yong believed that there were many chiseled and chiseled scriptures in some Confucian scriptures at that time, and there were many errors in the text. After the edict, Cai Yong personally wrote Dan in the stele, ordered the work to engrave, stood outside the Taixue Gate, the inscription is a total of 46 pieces, these steles are collectively called "Hongdu Stone Scripture", also known as "Xiping Stone Scripture", as a model for the world's readers to revise the text, for a while, the Taixue Gate is very lively, there are many people who come here every day to watch the Mo writing, there are as many as thousands of cars and horses, and the roads are blocked.

In addition, in terms of music, in addition to the story of Jiaoweiqin, which is talked about, Cai Yong also formulated the five alleys of the Cai family, "You Chun", "Lushui", "Meditation", "Sitting Sorrow", "Autumn Thoughts", and later Ji Kang, another music master, customized Ji's four alleys, namely "Changqing", "Short Qing", "Long Side", "Short Side", and "Short Side" and called the nine alleys of Qinqu, which even became one of the assessment standards for royal scholars after the Han Dynasty.

Of course, part of the interest of later generations in Cai Yong is from his daughters, Cai Yan and Cai Wenji, 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 a trance in a dream.

Cai Yong sat in the first place, and he didn't know how to deal with it. Cai Yong has not accepted disciples for many years, first, his reputation is getting heavier now, and he naturally has to be cautious about accepting disciples; second, the things that his daughter encountered, which really made him feel a little sad; The third is that he is getting older, and he really doesn't have the energy to teach wholeheartedly, so he simply closed the door and stopped accepting disciples, but now I don't know if Li Ru went there to find the token he gave to his friend before, and let people send it back, on the condition that he accept Feiqian as a disciple, which really makes Cai Yong embarrassed.

When Li Ru sent the token, of course, what he said was very casual, and it was very clear, clearly explaining that Fei Qian's father had been kind to him, and now he was a little successful, and when he learned that Fei Qian had the intention to study, he asked Cai Yong to find Cai Yong's token and asked Cai Yong to decide whether to accept it or not, anyway, he should have done it in place with a clear conscience.

The most important thing is this sentence "with a clear conscience", you Li Ru has a clear conscience, if I Cai Yong refuses, then what I said at the beginning, "Take this thing, do what you can, and everything is not allowed" is not a slap in the face, how can you "have a clear conscience", and I Cai Yong broke his word and became fat, so do you want to be a man?

Cai Yong looked at the young people in the hall, with a slender figure, introverted demeanor, and a delicate appearance, and he had more or less returned his eyes, but whether he accepted it or not, he felt a little congested, but everyone is here, so let's find out the bottom first, and ask first.

"What do you learn?" ――What did you learn and what are you good at?

"The kid is familiar with the Six Classics and prefers to count the Scriptures." Thanks to the blessing of the previous Fei Qian, most of the Six Classics still remember some, but if you want something like a small speech, you can't do it, but the arithmetic is different, just kidding, the future generations are also people who have gone to high school and college, let you Eastern Han people no matter how bull fork, have you seen the matrix, do you know calculus, and the probability theory of co-ordination......

In fact, Fei Qian also wants to say, not only that, but I also know a little "gutter washing", and "Bianae" and "Yamei Dad" also know a little, but unfortunately these things are not used at all in the Eastern Han Dynasty......

Cai Yong was quite surprised, because the arithmetic thing was one of the very cutting-edge knowledge in the Eastern Han Dynasty, and it was not played by ordinary people. At this time, the "Zhou Ji Sutra" was written only two or three hundred years, and the article is mostly obscure, even if you see the text without strong imagination and deduction ability, you are blind, for example, "Zhou Ji Sutra" has such a description, "If you seek the evil solstice, take the sun as the hook, the day high as the stock, the Pythagorean multiplication, and the prescription to remove it, get the evil solstice", this is the Pythagorean theorem, if you have to read or not understand, then the sutra will have nothing to do with you.

There is another book that is relatively better, and it is only a little better, that 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 disorderly, although it is closer to some specific problems in life, but it still belongs to the category of books that are not approachable.

Cai Yong was a little interested all of a sudden, after all, there are relatively few people who study this thing in this era, and it is difficult to find the same thing, so he casually came up with a question in the nine chapters to try: "Today, there is a Yi Fang who does not know the size, there is a wood twenty steps out of the north gate, fourteen steps out of the south gate and a thousand seven hundred and seventy-five steps to the west, ask the Yi Fang geometry?" Translated as a small square city, there is a big tree with a marker 20 steps out of the north gate, and then 14 steps out of the south gate and then 1775 steps to the west before you see the big tree with a marker, and ask for the area of this square town.

Don't look at the short question, but there are quite a lot of things involved, in addition to the basic number operation, the most important thing is to know the theorem of similar triangles, but also to know the solution of binary equations, which is a moderately difficult topic in the nine chapters of arithmetic, Cai Yong is also random to try to see if Fei Qian really understands the arithmetic.

But the difficulty of this middle school student question is not a problem for Fei Qian at all, so he asked Cai Yong for a pen and paper, drew a diagram, listed the equations, and directly calculated the answer.

Cai Yong stretched his neck to the side and watched, this picture can probably be guessed to be a schematic diagram, so what are these ghost drawings on the ABCD1234 picture? I suddenly felt itchy in my heart, but I felt a little embarrassed to ask.

Fei Qian had the intention to take out the 30 yuan math problem of the pit man in the later generations to show off, but think about it, forget it, after all, the 30 yuan house title itself is a bit misleading, and it is just a matter of talking about it on ordinary occasions, if it is seen through by others in front of this kind of Confucianism, will it be extended from the topic to people, it will not be fun, and it will not be good to fall into the name of "treacherous", and this life will basically be ruined.

So let's pretend to be honest, everyone likes honest people, doesn't it?

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

Cai Yongzai carefully weighed it, hesitated again and again, affirmed Fei Qian's arithmetic knowledge, and finally said: "Okay, and accept you as a famous disciple, every third and twelfth years of the first month, you can go to Taixue to listen to my teaching; On the fifth day of the Lunar New Year, if you have any questions, you can ask here, how about it? "A registered disciple is also a disciple, and it is not considered a violation of the previous promise, as for whether there will be a chance to turn positive in the future, I will talk about it in the future, first send the paper with Fei Qian's solution to the problem and ask the baby daughter if she can understand.
