Three Kingdoms.

  Chapter 1635 Sitting Well He Guantian

  Jia Xu took off his crown, flicked the dust off the bullet crown at random, and then put it back on his head again. If he didn't know that Li Ru is so clean, he would definitely be too lazy to do so.

   Can Hexi without wind and sand still be called the Hexi Corridor?

  Jia Xu said that he is used to it. Since there is wind and sand, he will still be blown to ashes later, so what's the point of playing now?

  Li Ru was still wrapped in fur, his face was thin.

   "This..." Jia Xu circled Li Ru twice, looked left and right, shook his head and sighed, "...Brother, your body..."

   "Ahem, don't worry..." Li Ru coughed lightly twice, "I won't be able to die for a while... This journey, what's going on in Guanzhong?"

   "Guanzhong..." Jia Xu laughed, and said while helping Li Ru forward, "It's alright... these guys are so honest, they don't even dare to fart..."

   Li Ru also smiled, and the two entered the meeting room and sat down.

   Li Ru and Jia Xu are not very cold about the gentry in Guanzhong. I think these guys are no longer worthy of the title of Guanzhong, just like domesticated domestic dogs, they have lost the bloodiness to fight and fight in the wild. Of course, what Li Ru was worried about was not the Guanzhong gentry, who had lost their feral dogs, and if they let them eat vegetables, they could eat vegetables, and if they let them eat shit, they could only eat shit, it didn't matter.

  Li Ru is more concerned about whether Fei Qian will stay in Guanzhong, and then stay, and then unconsciously, gradually lose the courage to move forward...

   Just like Dong Zhuo back then.

  Jia Xu glanced casually at the scrolls spread out on Li Ru's desk, apparently Li Ru was reading them, and couldn't help raising his eyebrows, "Talk about potential husbands?"

  Li Ru nodded, pointed to the scroll, and said, "What do you think of this book?"

"Tun Fu Lun" was written by Wang Fu of the Eastern Han Dynasty. Most of its contents are political articles discussing the art of governing the country and stabilizing the people. It covers a wide range of topics and basically covers everything. In the midst of "declining times", he cited classics and used historical lessons to exhort the rulers...

   "The book is a good book, but..." Jia Xu sneered, shook his head and said, "Sit in a well and watch the sky, how can you explain it?"

  Li Ru laughed twice, but seemed to be choked by his breath, coughed twice, and then said: "...That's the same... But, Wenhe, have you ever thought about why a person sitting in a well looks at the sky?"

   "Isn't it because of..." Jia Xu subconsciously wanted to answer, but stopped halfway through the speech, looked at Li Ru with a strange expression, "Brother, you mean..."

  Li Ru waved his hand, but did not answer.

   Both of them fell silent for a moment.

Wang Fu was the son of a concubine, and his uncle's family had no relatives, so he was discriminated against in his hometown. Because "I don't want the chapter to show its name", the title of the book is "On the Qianfu".

  Okay, here comes the question, who is this "submarine" of Wang Fu talking about? Naturally, it means that he himself is a submerged man, so is he willing to "submerge" or is he forced to "submerge"?

   Therefore, Wang Fu will not be an official for life.

Li Ru pondered for a long time, then slowly said: "After Guangwu, he stuck to Shandong and never made any progress. Why? You must know that the strategy of abandoning the west is not a one-day cold, and sitting on the wall of a well is not a one-day achievement. ..."

"In terms of national power, the beginning of Guangwu and the rule of Ming Zhang are not inferior to the time of Wenjing. The two capitals come out!" The master of the Eastern Capital sighed and said, "It hurts the customs to move people. He is a real Qin person, boasting about the halls and rooms, and protecting the rivers and mountains. He believed in Zhaoxiang and knew the first emperor. He didn't see the cloud of the great man." Why?'" Li Ru sighed.

  What is "Liangdu Fu"? It was written by Ban Chao’s brother, Ban Gu. Of course, it is said that he was ordered to write it... What’s more ironic is that Ban Chao worked so hard to go to the Western Regions, and Ban Gu easily wrote "Fu of Two Capitals" in the rear, and then obliterated Ban Chao A series of dedication and hard work...

  If there is no game above the court, who would believe it? There is no entanglement between families, do you believe it? There are no various problems of profit distribution, ghost letter?

  Is Emperor Guangwu only satisfied with being partial to Luoyang?

Obviously not. Back then, Guangwu also lamented that his country was not vast enough, but Taifu Deng Yu said that "those who prospered in ancient times were not judged by their virtues." relationship, so in the end Guangwu didn't move anymore.

  However, people are greedy and lazy, so they are too comfortable in one place, so they don’t want to move. Guangwu didn’t make up his mind. Although Emperor Ming of Han had this wish, Emperor Zhang of Han wiped out this wish. Emperor Zhang of the Han Dynasty has already been regarded as the third generation of emperors. He grew up in a comfortable environment since he was a child, so how could he understand Guangwu's last wish?

  The high wall was built like this, and the people in the middle gradually turned into frogs.

"There are children in Guanzhong who don't understand the ambition of hussars. There are many words in their words that isolate the barbarians and specialize in the Central Plains...whatever the outsiders need to be at home first..." Jia Xu also laughed, and then said, "I don't know the outsiders The internal and external are one, why is there a sequence? There are disputes inside and enemies outside. When will the time be exhausted? If you don’t take advantage of the time when the army is in full swing, do you still wait for others to come here to build up the land when the army is in decline? ? Guangwu's response, Mingzhang's loss, all of them are like this..."

"Nowadays the Xiongnu is attached to the interior, the Xianbei are fighting each other, and the Western Qiang is scattered. What's so wonderful about this?" Jia Xu continued, "The hussars have a deep heart, and the shallow people are naturally hard to match... Now that the hussars are valuable, it is inevitable that there will be more Those disciples of Deng and Cui, if it is because of this... so, it is not unreasonable for senior brothers to be worried..."

  Jia Xu suddenly laughed twice, raised his eyebrows, and said, "How about..."

  Li Ru set his eyes on the "Talk of the Hidden Husband" on the table, pondered for a long time, then slowly shook his head and said, "It's not time yet..."

   Jia Xu rolled his eyes. Okay, the topic you brought up, now you tell me that it’s not time yet, you are the senior brother, you are the boss, you have the final say...

   "However, we can make some preparations..." Li Ru suddenly changed the subject.

  Jia Xu burst out laughing, "I know!"

  Li Ru smiled slightly, ignored Jia Xu, stroked his gray beard, but looked into the distance...

  ...Here is the dividing line for jumping...

   Fei Qian, who was still in Guanzhong, naturally didn't know what kind of chemical reaction Li Ru and Jia Xu would have when they collided together. Fei Qian was now happy for Xu Yue's arrival.

  Xu Yue came all the way this time, and what he brought was the freshly baked calendar from his master Liu Hong...

  Calendar, some people think it doesn’t matter, after all, it’s not about fighting, it’s meaningless at all, but in fact, the calendar has a very important position in the history of China, and even in the improvement of the civilization of the whole society.

  Fei Qian knows that, generally speaking, the whole world is three-dimensional and a half. Of course, people like Fei Qian should be four-dimensional. Although this statement may not be completely accurate, it can also explain some problems.

  Understanding time and space, the flowers of civilization will bloom more brightly.

  People form the concept of "day" based on the phenomenon of alternation of day and night; But the problem is that among these three concepts, no one cares about each other, and they all play their own way.

And the calendar is to put these three awkward guys into a relatively regular framework, so that there are integer months in a year and integer days in a month, which is convenient for human beings to have an overall concept of time. cognition.

The complexity of the calendar problem lies in the two relatively large periods of the tropical year and the synodic month. It is too fragmented. The relationship between these two guys and the "day" even reaches several digits behind the decimal point. It's not as clear as palm to elbow, so the calendar always loses sight of the other, and can't coordinate the cycle of the year, month and day at the same time...

  In the ancient times, China used the Yellow Emperor calendar, that is, the heavenly stems and the earthly branches, and then set the age at four o'clock. Although it is relatively rough, it also laid the foundation for the Chinese calendar, and even part of the content has been used to later generations. In Taoism, the era of the Yellow Emperor is also regarded as the first year of Kaiyuan, which is 2697 years earlier than the era of **** in the West...

   Later, after the Warring States period, the Qin Dynasty ruled the world, and implemented the Zhuanxu calendar used by the Qin Dynasty. Later, at the beginning of the Han Dynasty, the twenty-four solar terms were added to the calendar for the first time, so that the people could be more clear about seasonal changes. It is called the Taichu calendar. Later, there were three calendars and four-point calendars, and the four-point calendar began in the second year of Yuanhe and has been used until the present.

  Because the month and the year are always somewhat different from the day, one year or two doesn't matter, ten years or eight years is fine, but one hundred years or two hundred years, the accumulated gap is very obvious. It's like a quarter calendar, which is actually very accurate. It is stipulated that a year is 365 days and a quarter, but it is because of the slight difference, and because the delay in the moon's change is not considered when dealing with the moon phase. , As a result, after more than a hundred years, there have been some problems both in the twenty-four solar terms and in the slowness of the lunar movement.

"...so five hundred and eighty-nine is used as a discipline, and one hundred and forty-five is used as a fighting method to complete this calendar..." Xu Yue said slowly, Fei Qian could hear every word clearly, but he couldn't hear any of them. Understand, "to control the slow disease and walk on the moon, the square is at the beginning of the four points...playing the turn of the yellow and the white, and retreating to the west..."

  Xu Yue narrated for a long time, and when he saw that Fei Qian was about to drop one eyeball to the ground and one eyeball to fly into the sky, he couldn't help but sighed, stopped, and stopped talking.

   "This...hehe..." Fei Qian was somewhat embarrassed.

  Xu Yue stroked his beard, hesitant to speak. Back then, Liu Hong praised Fei Qian in front of Xu Yue, saying that Fei Qian was good at numerology and knew things well, he was a rare talent who mastered advanced calendar arithmetic, but now it seems...

"This...boy, I have a question, this friendship between Huang and Bai should start with Luo, or start with Jidu..." A sudden question could not help but attract the attention of Xu Yue and Fei Qian. Looking back, it turned out to be Kan Ze said it on the sidelines. (Note to this chapter)

  Xu Yue was about to answer, when he suddenly realized, he couldn't help but widen his eyes, looked Kan Ze up and down again, and said, "Since you know yellow and white, you know that the moon passes by the week, so you should measure it?"

   Kan Ze glanced at Fei Qian, and said cautiously: "This... I also know that it is also mentioned in Liu Gong's scroll..."

Xu Yue was stunned for a moment, glanced at Kan Ze, then at Fei Qian, and then at Kan Ze, burst into laughter, waved to Kan Ze and said, "Sure enough, they are all definite numbers! Definite numbers! Haha, hahaha... Come here, come here, let me tell you..."

Laughing, Xu Yue took out the wooden tablet pen knife that he carried with him from his body, and scraped off the wooden tablet three times and twice, regardless of what was written on the wooden tablet before, and then explained to Kan Ze again while writing. One big and one small got together, leaving Fei Qian aside.

"this…"

  Xu Yuezheng was talking happily and ignored Fei Qian.

"that…"

   Kan Ze was listening attentively, but did not hear Fei Qian's words.

  Fei Qian(_);

  Okay, okay, you two have a chat, I'll go around and come back...

  Fei Qian had no choice but to sneak out of the side hall with his hands behind his back for Xu Yue and Kan Ze who were completely caught in an academic discussion...

   "My lord, this calendar..." Huang Xu hurriedly followed. He was worse than Fei Qian about the calendar, and he didn't know what he was talking about.

Fei Qian looked back at Xu Yue and Kan Ze who were still having a heated discussion, and said: "You don't understand this...it's nothing, but...this calendar is not for you and me, nor is it for the children of noble families It's decided... This calendar is made for farming and mulberry, it's made for the world..."

Before the Taichu calendar, all the farmers in the world needed the guidance of old farmers, when to do things, the weight of the three elders in the countryside was very important, and after the Taichu calendar was promulgated, many farmers could use the twenty-four solar terms When you judge the timing of farming by yourself, the weight of the three elders will gradually decrease. Until now, it is almost dispensable, and not every township or county must establish it.

  The calendar is equivalent to a light, illuminating the way for farmers in the illiterate world, and telling them what to do each month. This is a great time tool for both rulers and ordinary working people.

Due to the relationship of later generations, Fei Qian is quite familiar with the Gregorian calendar, but he basically has no concept of the original Chinese calendar system. In addition, he has a deeper understanding of the current social conditions in the Han Dynasty. A Gregorian calendar for later generations is actually useless, and I can't remember it at all. There are twenty-eight and twenty-nine days on the 30th day of the lunar month and the 30th day of the first month. Ten fingers may not be able to count clearly, let alone a water leak timer. This kind of the most clumsy thing is still only available to rich families.

For the vast majority of farmers and women, the only way to judge the time, apart from the length of the sun, is the moon in the sky. Therefore, an accurate twenty-four solar terms, an accurate synodic calendar, It is naturally more direct and effective than the Gregorian calendar.

Because the four-point calendar has been implemented for more than a hundred years, and now there has been a large deviation between the twenty-four solar terms and the lunar calendar, Xu Yue came with the latest calendar, which is undoubtedly for Fei Qian's current agricultural development. Production brings the latest time tools, which is also of great benefit to the development of the entire agronomy.

   "This calendar is very useful..." Fei Qian looked back, and then turned back to Huang Xu and said, "Let someone hurry up and invite Zijing to come... let's say there is a heavy treasure coming..."

When I was young, I played some Gundam games, and then there would be "Kedu Luohou Assassination Sword" and "Kedu Luohou Instant Destroyer Arrow". I don't care about it, probably I think these four words are very in line with the atmosphere of the second school...

   These two words probably spread from ancient India to China, and then to Benzi...

   Kedu Luohu just means to calculate the intersection angle of yellow and white, two points used for calculation in astronomy...

   It's almost like this, if you are interested, you can ask the boss to speak...
