Three Kingdoms

  Chapter 37 New troubles

  Liu Hong couldn't believe it, how could you know this thing at such a young age? Besides, I made this just now, how could Fei Qian know? Are there really so-called naturally intelligent people?

Fei Qian looked at the "abacus", and finally understood why he always had an awkward sense of familiarity. The familiarity was because he had learned this calculation method when he was in elementary school. The awkwardness was that the abacus held beads one by one. Put it into the grid on the middle layer, instead of stringing a wooden stick in the middle of the beads to move up and down.

   "Why not use wooden sticks to string them together?" Fei Qian thought so, and said it casually.

   "What kind of wooden stick do you use?" Liu Hong asked Fei Qian puzzledly. Could it be that my abacus, which I have worked so hard to come up with, has any shortcomings?

   "This..." Fei Qian hesitated, maybe I want to order some strange technology tree to come out?

  When was the ancient Chinese abacus finalized? Tang Dynasty or earlier? Anyway, the Song Dynasty must have existed. I remember that in the Qingming Riverside Picture, there are abacus on the counter of the shop, and the form is basically the same as the modern one.

   Now point out this abacus, it shouldn't have any impact, right? Fei Qian thought to himself, but he said it himself, and it was hard to take it back, so he just asked for a piece of paper, and drew out the abacus of future generations.

Liu Hong waited for Fei Qian to finish the painting, grabbed it in his hand before Cai Yong, nodded, and praised, "Yeah, why didn't I think of it... In this way, I won't be afraid of losing it. The pearl of the pillar, the sky and the earth increase with man, tsk tsk... wonderful! wonderful!"

   "Heaven and earth increase more than people" actually means that the top row of beads is called sky beads, and the bottom beads are called earth beads. When calculating, it is the combination of sky beads and earth beads, which coincides with the three talents of heaven, earth and man, so it is said so.

However, Liu Hong also found something he didn't understand. Pointing to the abacus drawn by Fei Qian, he said: "Why do you need to add two beads of heaven and five beads?"——If modern abacus uses decimal system, in fact, the top one is the same as the last one. The bottom one is not used, but Fei Qian directly painted it in the form of a modern abacus without thinking too much.

  Fei Qian didn’t know why the modern abacus added these two unused beads, so he said: “The lower beads make five into one, and the upper beads make two, so it’s easier to calculate.”

   "The lower bead is five to one, and the upper bead is two to one..." Liu Hong nodded after hearing this, and shook his head again, making Fei Qian wonder whether Liu Hong agreed with him or disagreed.

  Actually, Fei Qian is not a professional after all, and he doesn’t know the development history of abacus, so naturally he doesn’t know the evolution of abacus.

During the development of abacus, it has gradually spread from a small number of people who study mathematics to people who need to deal with a large number of numbers, and a large part of them are merchants. Moreover, in ancient times, there were not only decimal calculation modes, but also hexadecimal calculation modes. For example, in ancient times, one catty was sixteen taels, etc. Therefore, for the convenience of calculating the hexadecimal system, merchants added one heaven and earth beads to the ancient abacus, so that the sum of heaven and earth beads equals fifteen, which happens to be used As for decimal, it can also be used for hexadecimal.

  Liu Hong stared at Fei Qian with piercing eyes. If he wanted to take Fei Qian as his apprentice, he just said it casually, but now he really has this idea. This son is also good at arithmetic, and he improved the abacus that I have been pondering for so long in a short time. Alas, how could he be overtaken by old man Cai?

Cai Yong also saw something coming from the side, pondered for a while, and simply said: "Ziyuan is my new recruit, although he has already started, but it is not an auspicious day, and it coincides with the autumn class of Taixue tomorrow, so let's salute together. If Yuan Zhuo is free, can he watch the ceremony?"

  Tai Xue in the Han Dynasty generally recruited a group of new students in spring and autumn, the so-called spring class and autumn class. Before Taixue suffered from the disaster of the party, it was closed for a period of time. Later, Emperor Hanling rehabilitated the party, and naturally reopened Taixue.

Liu Hong looked at Cai Yong, nodded, sighed, and immediately said: "Naturally, he will come." - Now there is no hope at all, this kid is Cai Yong's man, so he can't grab it, so he just But hey-

  Seeing that Liu Hong agreed, Cai Yong didn't say anything more, and told Fei Qian to go get ready. Don't miss the hour tomorrow, and let Fei Qian go back first.

  Fei Qian waited until he got out of the Cai Mansion, but he still didn't believe it. It's only been a few days. It seems that he has upgraded?

  Just now Cai Yong said to go back and prepare, what should be prepared? Naturally, it is the ceremony of apprenticeship, which means that Fei Qian will get rid of the word "recording his name" and become Cai Yong's real disciple as long as he has the ceremony of apprenticeship in Taixue tomorrow.

  This is really happiness, don't come suddenly...

However, Fei Qian suddenly thought of a problem, and couldn't help feeling dizzy. Originally, he planned to leave Luoyang for the reason of going to Jingxiang to study in a few days, but now he was accepted as a disciple by Cai Yong, and the reason became a joke. Then how can I leave Luoyang?

  If you can't leave, how can you keep your own life in this turmoil?

  This is really a plan that can never catch up with changes. What should I do?

  ******************

  Actually, Fei Qian is far from the only person who has troubles now.

  Yuan Wei is one of them. He was also very troubled after Yuan Shao resigned and left.

  Yuan Shao's departure is no less than exposing the dispute between the Yuan family's heir and concubine to the world. In fact, this matter is unavoidable for every family, but most of it is digested silently within the family, and few people like Yuan Shao's actions have made people all over the world know about it.

   And the most important point is that it was used by others.

  Dong Zhuopifu actually appointed that Nizi as the prefect of Bohai Sea! This made it clear that the two sons of the Yuan family were going to fight each other, but it was a pity that Yuan Kai couldn't say no.

On the surface, the Yuan family has always put the world's society as the most important thing, and it is an example of Qingliu. Now Dong Zhuo, in the name of the court, said that although Yuan Shao had minor faults, he was still usable. Therefore, he worshiped the prefect of Bohai to protect the good people, eliminate banditry, and make up for his mistakes. …

   Everything is blocked, what else can Yuan Wei say? Don't let Yuan Shao serve as the prefect? Why? Is it because the children of the Yuan family are incompetent? Do you not want to serve the court? Or don't let you make up for your mistakes? Or do you want to issue a hunting order for thousands of miles to hunt him down immediately?

  Although Yuan Kui really wanted Dong Zhuo to hunt him down thousands of miles, but the laws of the Han Dynasty stipulated that it was reasonable and legal for relatives to hide each other. Could it be that Yuan Kai could really kill relatives with the law of the Han Dynasty behind his back?

  The extermination of relatives is really not a good term in the Han Dynasty. Do you want the reputation of the Yuan family? So Yuan Kai had no choice but to admit it with his nose pinched.

  However, Dong Zhuo and Li Ru were allowed to mix sand into Yuan's house like this. After thinking about it, Yuan Kai was still unwilling, so he ordered his servants to call Yuan Shu.

  Since it’s no longer possible to hide it, let’s just put it on the table in an upright manner! Let everyone in the world see the courage of my fourth generation and third father's Yuan family!

   It’s not easy for a newcomer, please recommend a ticket for collection... The author worships it... Thank you a708020 book friend, the Three Kingdoms is even more exciting with you...
