  Chapter 19 Named Disciple

  A few days later, Fei Qian really did not expect that Li Ru would recommend him to Cai Yong.

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

  Eastern Han Dynasty great writers, great historians, great musicians, great painters, great calligraphers, so many of you come down, 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 later generations.

  At that time, he was in the period of Emperor Ling. Cai Yong believed that some of the Confucian classics at that time contained many inaccuracies and inaccuracies. In order not to delay future studies, he specially requested to correct these scriptures. After the approval of the imperial edict, Cai Yong personally wrote the pill on the stele, ordered the craftsmen to engrave it, and stood outside the gate of Taixue. There are 46 steles in total. These steles are collectively called "Hongdu Stone Classic", also known as "Xiping Stone Classic". All of a sudden, the gate of Taixue was bustling with people from all over the world to revise the text. There are many people who come here every day to watch and write. There are thousands of vehicles and horses, and the roads are blocked by it.

In addition, in terms of music, in addition to the story of Jiao Weiqin, which has been talked about so much, Cai Yong also formulated the five songs of the Cai family, "You Chun", "Lu Shui", "Melancholy", "Zuo Sorrow", "Autumn Thoughts", etc. ", and later with Ji's four lanes customized by another musician Ji Kang, namely "Changqing", "Short Qing", "Long Side" and "Short Side", they were also called Qinqu Nine Lanes. After the Han Dynasty, they even became royal One of the assessment criteria for obtaining a scholar.

  Of course, part of the interest of later generations in Cai Yong comes from his daughters, Cai Yan and Cai Zhaoji, so I won’t say much about that.

  So when Li Ru informed Fei Qian that he had recommended him to Cai Yong, Fei Qian really couldn't believe it. When he entered Cai's mansion, he still felt a little bit like a dream.

  Cai Yong sat at the top of the table, and he didn't know how to deal with it. Cai Yong has not accepted disciples for many years. One is that his reputation is getting worse now, so he must be cautious about accepting disciples; second, the shabby things his daughter encountered really made him feel sad; third, his age Growing up, I really didn't have much energy to teach with all my heart, so I simply closed the door and stopped accepting disciples, but now I don't know where Li Ru went there to find the token he gave to his friends before, and someone sent it back, the condition is to collect Fei Qian. As a disciple, this is really embarrassing for Cai Yong.

When Li Ru delivered the token, of course, he said it casually and clearly, explaining clearly that Fei Qian's father had once been kind to him, and now that he has achieved a little success, he learned that Fei Qian wanted to study, so he relied on his relationship. Find Cai Yong's token, whether to accept it or not is up to Cai Yong to decide, anyway, he has done what he should do and has a clear conscience.

The most important thing is this sentence "with a clear conscience", you Li Ru have a clear conscience, if I, Cai Yong, refuse, then what I said at the beginning, "hold this thing, do what you can, and everything is not allowed", wouldn't it be self-defeating? How can I "have a clear conscience" when it is said that I, Cai Yong, broke my promise and became fat, so should I be a human again?

Cai Yong looked at the young man in the hall, he was slender, restrained in charm, and handsome in appearance, and he was more or less passable, but whether he accepted it or not, he felt a little heartbroken, but everyone came, so he should touch it first. To get to the bottom of it, ask first.

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

"The boy is proficient in the Six Classics, and prefers to calculate the Classics." Thanks to the previous Fei Qian, he can still remember most of the Six Classics, but Fei Qian can't do it if he wants to talk about things in a subtle way, but the calculation of the Classics is different. Just kidding, the future generations are also people who went to high school and college, no matter how awesome you are from the Eastern Han Dynasty, have you ever seen matrices, do you know calculus, and the probability theory of overall planning...

  Actually, Fei Qian wanted to say, not only that, but I also know how to "wash in the gutter", and "Bianey" and "Daddy Yamei" also know a little bit, but it's a pity that these things were 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 written only two to three hundred years ago, and the articles were so obscure that those without strong imagination and deduction ability would be blinded even if they saw the text. For example, there is such a description in "Zhou Bi Suan Jing", " If you are looking for the evil solstice, take the lower sun as the hook, and the higher sun as the stock, multiply each of the Pythagorean shares, and draw the square to get rid of them, and you will get the evil solstice." This is the Pythagorean theorem. If you don't understand it, Then the scriptures will have nothing to do with you.

There is another book that is relatively better, but only a little bit better, and it is the famous "Nine Chapters of Arithmetic", but at this time "Nine Chapters of Arithmetic" has not been sorted and annotated by Liu Hui, and it is still very messy and disorderly. Although it is relatively close to some specific problems in life, it still belongs to the kind of book that is 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 a tree in twenty steps, turn 14 steps out of the south gate and turn westward at 1,775 steps to see the wood, how about the town?”—translation means there is a small square town, and there is a tree 20 steps out of the north gate Take the big tree as the marker, and then walk 1775 steps westward after 14 steps out of the south gate before seeing the big tree as the marker. Find the area of ​​this square town.

Although the topic is short, it involves quite a lot of things. In addition to basic number calculations, the most important thing is to know the theorem of similar triangles and the solution of linear equations in two variables. This is a medium-difficulty topic in Chapter Nine Arithmetic Yes, Cai Yong also randomly took it out to try to see if Fei Qian really understands arithmetic.

  But this difficult question for middle school students is not a problem for Fei Qian at all. He asked Cai Yong for a pen and paper, drew a picture, listed the equation, and directly calculated the answer.

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

Fei Qian intends to show off the cheating 30 yuan math problem in later generations, but after thinking about it, forget it. After all, the 30 yuan hotel question itself is a bit misleading. If Chong Confucianism is seen through by others, will it be extended from the topic to people?

  So let’s pretend to be honest, everyone likes honest people, don’t they?

  Fei Qian finished his calculations, and stood with his hands down, pretending to be an obedient student.

Cai Yongzai weighed it carefully, hesitated again and again, affirmed Fei Qian's knowledge of arithmetic, and finally said: "Forget it, let's accept you as a famous student. On the third and twelfth day of the junior high school, you can go to Taixue to listen to my lectures; Fifth, if you have any questions on the 20th day of the lunar new year, you can come here and ask, how about it?" Registered disciples are also considered disciples, and it is not a breach of the previous promise. As for whether there will be a chance to become a regular in the future, we will talk about it in the future. Ask the baby girl if she can understand the piece of paper that solves the problem.

   The 30 yuan math problem is nothing more than that misleading sentence. In ancient times, once this kind of cleverness was discovered, its reputation would be ruined, let alone in front of the big shots. All kinds of requests for newcomers, collection and recommendation for motivation
