Three Kingdoms

Jia Xu took off his crown, flicked the dust off it casually, and then put it back on his head. If he hadn't known that Li Ru was so clean, he would have been too lazy to do this.

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

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

Li Ru was still wrapped in fur, with a thin face.

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

"Ahem, don't worry..." Li Ru coughed twice, "I won't die for a while... How is Guanzhong going along this way?"

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

Li Ru also smiled, and the two of them entered the meeting hall and sat down.

Li Ru and Jia Xu were not very fond of the nobles in Guanzhong. I think these guys are no longer worthy of the title of Guanzhong. They are just like domestic dogs that have been domesticated and have lost the bloody spirit of tearing and killing in the wild. Of course, what Li Ru is worried about is not the Guanzhong gentry who have lost their wild domestic dog. If it eats vegetables, it can only eat vegetables, and if it eats shit, it can only eat shit. It doesn't matter.

Li Ru was more concerned about whether Fei Qian would stay in Guanzhong, and then he would stay there, and then unknowingly, he would gradually lose the courage to move forward...

Just like Dong Zhuo back then.

Jia Xu casually glanced at the book spread out on Li Ru's desk. It was obvious that Li Ru was reading it, and he couldn't help but raise his eyebrows, "The theory of latent husbands?"

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

"Qianfu 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 bringing peace to the people. It covers a wide range of topics and basically covers everything. It makes extensive and sharp criticisms of the court in the late Eastern Han Dynasty and believes that the Eastern Han Dynasty is already in the " "Amidst the decline of the times", he quoted scriptures and used historical lessons to admonish the rulers...

"The book is indeed a good book, but..." Jia Xu sneered, shook his head and said, "Sitting in a well and observing the gods, how can we understand it?"

Li Ru laughed twice, but seemed to be choked by his breath. He couldn't help coughing twice before saying: "...That's true... But has Wen He ever thought about why people sitting in wells look at the sky? ?”

"Isn't it because..." Jia Xu subconsciously wanted to answer, but stopped mid-sentence and looked at Li Ru with a strange look on his face, "Senior brother, you mean..."

Li Ru waved his hand and did not answer.

The two of them were silent for a while.

Wang Fu was the son of a concubine and had no relatives in his uncle's family, so he was discriminated against in his hometown. He was also unscrupulous and did not ask for introductions. Therefore, he was not promoted as an official, so he became angry and lived in seclusion and wrote books. He stayed out of office all his life. He ridiculed the gains and losses of current affairs. Because he "didn't want his name to appear in the chapter", he titled his book "The Theory of Qianfu".

Okay, here’s the question, who is Wang Fu’s “hidden husband” talking about? Naturally, he is a lurker himself, so is he willing to lurk, or is he forced to lurk?

Therefore, Wang Fu will not be an official for the rest of his life.

Li Ru pondered for a long time and then said slowly: "After Guangwu, we just stuck to Shandong and never made any progress. Why? It should be noted that the strategy of abandoning the West is not a day's cold, sitting on the wall of a well, nor a day's work. …”

"In terms of national strength, at the beginning of Guangwu and Mingzhang's rule, it was not inferior to that of Wen and Jing. In terms of generals, Dou Po Shao was in charge, and the group controlled the Western Regions, and it was not inferior to Wei Huo's talents. However, there is " "Liangdu" came out!' The master of the Eastern Capital sighed and said, it is painful to change the customs. He is a native of Qin, boasts about his palace, protects the borders, rivers and mountains, his faith and knowledge are clear, and he knows the first emperor, and he sees the clouds of the Han Dynasty. Why?'" Li Ru sighed.

What is "Liangdu Fu"? It was written by Ban Chao's brother, Ban Gu. Of course, it was said to be written under orders... And what's even more ironic is that Ban Chao worked hard as an envoy to the Western Regions, and Ban Gu easily wrote "Liangdu Fu" in the rear, and then obliterated it. Ban Chao’s series of dedication and efforts...

If there is no game above the court, who would believe it? There is no grievances between families in this, do you believe it? There are no various issues of profit distribution, Guixin?

Was Emperor Guangwu just content with settling in Luoyang?

Obviously not necessarily. At that time, Guangwu also lamented that his country was not vast enough, but the Taifu Deng Yu said, "The prosperity of the ancients depends on the depth of virtue, not the size." In addition, the world was initially settled, people's minds were stable, and there were Shandong nobles. relationship, so in the end Guangwu did not move again.

However, people are lazy and slanderous, so they feel too comfortable in one place and don't want to move. Guangwu did not make this determination. Although Emperor Ming of the Han Dynasty had this wish, Emperor Zhang of the Han Dynasty wiped out this wish. Emperor Zhang of the Han Dynasty was already the third generation emperor. He had grown up in a comfortable environment since he was a child. How could he understand Guangwu's last wish?

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

"There are also disciples in Guanzhong who don't understand the ambition of the Hussar. Many of their words talk about isolating the barbarians and specializing in the Central Plains...those who are obsessed with outsiders must first be content with the inside..." Jia Xu also laughed, and then said, "I don't know. The inner and outer peace of Tao are one, so how can there be any order? There are disputes inside and enemies outside, so when will the time come to an end? If we don’t take advantage of the prosperity of the military to open up the frontiers, how can we wait until the day of decline and let others come here to open up the territory? Is it soil? The response of Guangwu and the failure of Mingzhang are all like this..."

"Nowadays, the Xiongnu are attached, the Xianbei are fighting, and the Western Qiang are scattered. Why is it so wonderful?" Jia Xu went on to say, "The Hussar has a deep heart, and it is naturally difficult for ordinary people to look up to him... Nowadays, the Husband has a high status, and it is inevitable that there will be many I have some disciples of Deng and Cui, if it is because of this... So, senior brother is not unreasonable to worry..."

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

Li Ru cast his eyes on "The Theory of Hidden Husbands" on the table. He pondered for a long time, slowly shook his head and said, "It's not the right time..."

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

"But we can make some preparations..." Li Ru suddenly changed the topic.

Jia Xu burst out laughing immediately, "You know it!"

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 would occur if Li Ru and Jia Xu collided. Fei Qian was now happy for Xu Yue's arrival.

Xu Yue came all the way this time, and what he brought with him was the fresh calendar made by his master Liu Hong...

Some people think that the calendar does not matter. After all, it is not about fighting and killing, and it is not interesting at all. But in fact, the calendar has a very important position in the history of China, and even in the advancement of civilization in the entire society.

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

Only when we understand time and space can the flowers of civilization bloom more brightly.

People formed the concept of "day" based on the phenomenon of the alternation of day and night; the concept of "month" was formed based on the waxing and waning of the moon; and the concept of "year" was formed based on the phenomenon of the alternation of four seasons. But the problem is that among these three concepts, no one cares about the other, they all play their own roles.

The calendar is to put these three awkward guys into a relatively regular framework, so that there are whole months in a year and whole days in a month, which facilitates human beings' overall concept of time. cognition.

Does the complexity of the calendar problem all lie in the two relatively large cycles of the tropical year and the synodic month? It is really too fragmented. The relationship between these two guys and the "sun" even reaches several decimal places. It's not as clear as the palm to the elbow, so the calendar always cares about one thing and misses the other, and cannot coordinate the cycle of the year, month and day at the same time...

In ancient times, China used the Yellow Emperor calendar, which was based on the combination of heavenly stems and earthly branches, and then determining the four seasons of the year. Although it was relatively crude, it also laid the foundation for the Chinese calendar, and even part of the content was still used in later generations. In Taoism, the Yellow Emperor's Era is also regarded as the first year of Kaiyuan, which is 2697 years earlier than the Western Era of Jesus...

Later, after the Warring States Period, the Qin Dynasty unified 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, allowing the people to understand seasonal changes more clearly, and called it the Taichu calendar. Later, there were three unified calendars and four-point calendars, and the four-point calendar started in the second year of Yuanhe and has been used until now.

Because the month and year are always slightly different from the day, one or two years does not matter, ten or eight years is just fine, but one hundred or two hundred years, the accumulated gap will be very obvious. Just like the quarter calendar, it is actually very accurate. It stipulates that a year is 365 days and one quarter, but it is just because of the slight difference, and because the delay of the moon's transformation is not considered when dealing with the moon phases. As a result, more than a hundred years later, there have been some problems, both in the twenty-four solar terms and in the slow movement of the moon.

"...Therefore, we use five hundred and eighty-nine as the discipline and one hundred and forty-five as the fighting method to achieve this..." Xu Yue said slowly, Fei Qian could hear every word clearly, but they were all I don't understand, "He also suppressed Chi Ji and marched on the moon, and then arrived at the fourth quarter of the Taichu period...acted at the intersection of Huang and Bai, and retreated to the west..."

Xu Yue told the story for a long time. When he saw Fei Qian, one of his eyeballs almost fell to the ground and one of his eyeballs flew into the sky. He couldn't help but sigh, stopped and stopped talking.

"This...hehe..." Fei Qian was a little embarrassed.

Xu Yue touched his beard and stopped talking. At that time, Liu Hong had many praises for Fei Qian in front of Xu Yue, saying that Fei Qian was good at numeracy and knew things well. He was a rare talent who could master advanced calendar arithmetic. But now it seems...

"This... I have a question. Should the acquaintance between Huang and Bai start with Luo or Jidu..." A sudden question couldn't help but attract the attention of Xu Yue and Fei Qian. They looked back. It was Kan Ze who said it on the side. (notes in this chapter)

Xu Yue was about to answer when he suddenly realized what he was doing. He couldn't help but widen his eyes. He looked Kan Ze up and down again and said, "Since you know the yellow and the white, do you know how to measure the moon's passage?"

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, glanced at Kan Ze, then at Fei Qian, and then at Kan Ze. He burst into laughter, waved to Kan Ze and said, "It's indeed a given! It's fixed! Haha, hahaha... …Come, come here, I’ll tell you…”

Xu Yue smiled and took out the wooden tablet pen knife he carried with him. Regardless of what was written on the wooden tablet before, he scraped it away, and then started writing and explaining to Kan Ze again. Suddenly, The big one and the small one gathered together, leaving Fei Qian aside.

"this……"

Xu Yuezheng was talking happily and ignored Fei Qian.

"that……"

Kan Ze was listening intently and didn't hear Fei Qian's words.

Fei Qian (?_?);

Okay, okay, you two have a chat for a while, and I’ll come back later...

Fei Qian had no choice but to sneak out of the side hall quietly with his hands behind his back...

"Lord, this calendar..." Huang Xu hurriedly followed. Regarding the calendar, he was even worse than Fei Qian, and he was even less clear about what he was talking about.

Fei Qian looked back at Xu Yue and Kan Ze, who were still having a heated discussion, and said, "It doesn't matter if you don't understand this, but... this calendar is not for you and me, nor is it for It is determined by the sons of the noble clan... This calendar is made for farmers and mulberry trees, and it is made for the world..."

Before the Taichu Calendar, all farmers in the world needed the guidance of old farmers to guide them in farming. The three elders in the countryside had a very strong weight. However, after the Taichu Calendar was promulgated, many farmers could guide them according to the twenty-four solar terms. When you decide the timing of farming by yourself, the weight of the three elders will gradually decrease until now, they are almost dispensable, and not every township and county must set them up.

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

Fei Qian is relatively familiar with the Gregorian calendar because of his later generations, but he basically has no idea about the original Chinese calendar system. In addition, with a deeper understanding of the current social conditions of the Han Dynasty, he understands that for a farmer and a peasant woman, The Gregorian calendar of later generations is actually of no use, and it is impossible to remember the thirty-first month, the thirty-first month, and the twenty-eight and twenty-nine days. Farmers and women cannot recognize a few big characters, and they can’t even count them. It may not be possible to count them clearly with ten fingers, let alone a water leakage timer. This most cumbersome thing can only be found in wealthy 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 waxing and waning of the moon in the sky. Therefore, an accurate twenty-four solar terms and 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, there has now been a large deviation between the twenty-four solar terms and the lunar calendar. Xu Yue came with the latest calendar, which undoubtedly gave Fei Qian the current agricultural development. Production brings the latest time tools, which is also of great benefit to the development of agriculture as a whole.

"This calendar is of great use..." Fei Qian looked back, then turned back to Huang Xu and said, "Have someone hurry up and invite Zijing... Just say that a valuable treasure has arrived..."
