Chapter 2026: A broken mirror is hard to round, the lunar calendar
"The envoy has returned home!"
With a loud announcement, everyone in the Liu Mansion started to move. The servants hurriedly arranged the utensils used by Liu Biao, then reached out and touched the corner of the table to confirm again that there was no dust at all before giving up and going again.
He quickly added fire to the refreshing drink that was warm on the small red clay stove, and when he heard a loud gurgling sound, he quickly took it down and placed it in the warmer to wait.
Several maids serving in the inner courtyard came to greet Liu Biao at the entrance of the courtyard. When they saw Liu Biao, they stepped forward to help him gently, then turned into the screen, changed out of their red and black crown clothes, and changed into ordinary casual clothes.
"Where is Cong'er?"
Liu Biao asked.
If you look at him from a distance, Liu Biao's face is ruddy and his bearing is extraordinary. But if you look closer, you can see that the thick powder on Liu Biao's face has cracked a lot as he speaks and moves, and some dust falls with his words.
.
Today was the day of the sunrise, and as usual, he had to meet with officials from all over Jingzhou. In order not to show his sick look on his face, Liu Biao applied more powder than usual.
Asian magic has been spread since ancient times.
At this time, Liu Cong was in the inner study, and he couldn't calm down. On normal days, he would still have the bearing of a noble man, but now he has no grace at all. He is wandering around in the study with his hands behind his back. Why?
Can't stop either.
It's no wonder that he, at this moment, even a fool knows that something is wrong...
Needless to say, the Liu guards standing outside the study already explained some problems.
The sound of noise came from the outer courtyard, and not long after, someone came to the study, cupped his hands and said, "Sir, I have sent you to summon me."
Liu Cong hurriedly ran out. After seeing Liu Biao, he breathed a sigh of relief.
"Father..."
Liu Cong bowed his head to greet him.
"Come in!"
Liu Biao sat calmly. Even though Liu Biao was sitting calmly now, he was full of various thoughts in his heart.
"Father..."
Liu Cong came to his side and whispered again.
"Sit..." Liu Biao glanced at Liu Cong.
"Father..." Liu Cong spoke again.
Liu Biao frowned, and the powder on his face fell a little more, "I said, sit down!"
"Oh, oh..." Liu Cong then sat down.
Ever since Cai had his plans, Liu Biao had imprisoned Cai in the backyard. The entire mansion was basically under the control of Liu's guards, and Cai Mao had also lost most of his military power.
As for why Liu Biao didn't completely kill the Cai family and still kept it for the New Year, could it be that Liu Biao was fooling around and was forcibly subdued by Ma Hou?
it's actually really easy.
The Cai family has deep roots in Jingxiang. Liu Biao's wife is the Cai family, Liu Cong's wife is also the Cai family, and how many other families have wives who are also the Cai family? If they had directly killed the Cai family at that time, they would have gotten into a twisted relationship with the Cai family.
Doesn’t the cavalry general have a reason to go south? What if the cavalry really takes Liu Qi south? And whether it is Pang Degong or Huang Chengyan, if one of them really stands up, believe it or not, Liu Biao may not even be able to control Xiangyang!
Now that Cai Mao was slowly squeezed out of the army, and the power of the army fell into the hands of Gan Ning, Liu Biao felt that his waist was no longer cold, and he had the courage to attack Cai.
What? Cao Cao killed Cai Mao?
Ha, that's the Romance of the Three Kingdoms.
The real history is that "after Liu Cong's defeat, Cao Cao visited Mao's house, entered Cai Mao's private room, and called to see his wife and children." Then Cai Mao was appointed to two thousand shi, and was granted the title of Marquis of Yangting in Han Dynasty until his death. He was nothing like Zhou Yu.
thing.
So why is Liu Biao starting to plan for the Cai family again now? After all, it is difficult to reunite a broken mirror. Cracks have already occurred. Is it possible to return to its original appearance?
Liu Biao knew this, and so did Cai Mao.
Also, have times changed...
Just like those big tigers in later generations, when they were entrenched in the place and roared on the hills, no one heard it, no one knew it, no one reported it? Haha, but why not deal with it directly and wait until the heat is high before taking the pot?
Therefore, Liu Biao believed that now, the time has come.
After the Cai family was suppressed, Huang Zhong opened up the Wuguan Road and began to transfer some things to the north one after another. Gold, silver, jewelry, valuable utensils, and even family members...
Zhuge Liang went to Chang'an and then stayed in Chang'an. It is said that the Ma family and the Chen family were preparing to go to Chang'an.
Then, the three auxiliaries in Guanzhong, north of the river, Jizhou and Qingzhou are prone to natural disasters!
Fei Qian asked his soldiers to assist in farming and rescue Zhuang He...
Cao Cao was busy winning over the gentry and common people of Jizhou in Yecheng...
Everyone is busy, which is good. After finishing the Cai family, they will catch up with the autumn harvest, and then they will be busy again. After the end of autumn, Liu Biao will be able to stabilize Jingxiang, and then pass the position to Liu Cong first, taking advantage of the opportunity.
Help Liu Cong as much as possible while he can still breathe, so that Liu Cong can accumulate as much capital as possible...
As for the future, it all depends on Liu Cong. So Liu Fang now takes Liu Cong with him, which can be regarded as teaching by words and deeds.
So, could there be a better time than now?
Coupled with Zhang Ji's escape, it was the last straw. If Zhang Ji and Zhang Zhongjing were still there, Liu Biao would still have some hope, but now with only the prescriptions left by Zhang Ji, he could not make it in time.
How long can Liu Biao's broken body last through acupuncture conditioning and increasing or decreasing the dosage?
Jingxiang is the Jingxiang of the Liu family, not the Cai family!
Before you can move, you must sweep away all the thorns for Liu Cong!
Liu Biao deliberately exposed his body today, just to use his body as bait in an attempt to catch Cai Hao. He didn't believe that Cai Hao hadn't read the "suicide note", he was writing it to Cai Hao!
But the question is, why didn't Cai Mao take action today?
"Emergency military report!"
Suddenly a loud shout broke the silence.
"There is a thief in Yunmengze. He calls himself General Tiger Roar, calls a hundred thousand people, and marches towards Jiangling!"
……(⊙＿⊙；)……
Chang'an.
Lishan Mountain is a place for observing astronomy.
A coo-coo flew past the sky with a cry. Fei Qian looked up and vaguely saw something on the pigeon's legs, and his heart skipped a beat.
Huang Xu also saw it and said: "Master, how about..."
Fei Qian waved his hand, "Since we've already reached the bottom of the mountain, there's no rush. We'll talk about it when we get back."
Under Lishan Mountain, Kan Ze was already waiting.
When Fei Qian came here, there was naturally something going on.
What does it mean to be crazy and obsessed? Fei Qian understood it when he met Xu Yue.
Xu Yue's hair was disheveled and his whole body was in a state of wretchedness. He didn't look like a gentleman at all. His robes were scattered, and he was staring at Tugui's dial with his butt sticking out. He had no idea that Fei Qian had already walked beside him.
Huang Xu frowned and was about to step forward, but was stopped by Fei Qian.
Fei Qian looked at Xu Yue's engrossed state and forgot everything, so he simply stood back and signaled not to disturb Xu Yue and others.
Only if a nation has people looking at their feet and people looking up at the stars can this nation have hope.
For early Chinese people, looking up at the starry sky was basically to conduct a relatively basic exploration of the cycle changes of the sun, moon, and stars.
Basic, but does not mean original.
The cultural inheritance of nomadic people is relatively lacking, and it is naturally difficult to establish a connection between the sun, moon, stars and livestock. People who mainly focus on farming pay special attention to the climate and weather, so how to determine the season based on time, and related
A series of agricultural activity guides, such as temperature, water flow, sun and moon rise and fall, etc., have become the lifeblood of agricultural farming.
In this process, because the moon is closer to the earth, the change cycle is very obvious, so almost all farming peoples of ancient cultures, such as ancient Egypt, Babylon, ancient India, ancient Greece, etc., all adopted this method of using the moon phase.
A calendar formulated based on changes in the laws of China, that is, the lunar calendar.
Fei Qian had always thought that ancient China had a lunar calendar, that is, a calendar based on the moon, but in fact, this is not the case...
As the only ancient civilization that has continued for generations to come, the Han calendar has withstood the test of time under the rotation of the sun and moon for thousands of years. The Han calendar used by later generations is said to have been created in the Xia Dynasty, so it was called the Xia calendar until modern times.
It was then renamed the lunar calendar. Because the moon and the sun are not synchronized, and the ancient people's measurement methods were not very accurate, there often were some large deviations. In order to make up for this problem, the concept of the solar calendar was incorporated
, that is, a calendar based on the temperature changes of the sun. So to be precise, the lunar calendar of later generations is actually a lunar calendar based on the changes of the moon phases and mixed with some contents of the solar calendar in order to improve the accuracy of farming and the suitable farming times.
calendar.
The Han Dynasty was the beginning of these calendars, including the chronology of the heavenly stems and earthly branches that lasted for thousands of years and was still used in later generations. It also started from this era...
"That's not right..." Xu Yue frowned, his eyes fixed on Tu Gui, and then he grabbed the records on the wooden tablet beside him to calculate, "That's wrong... How could it be wrong...
its not right……"
Fei Qian sighed slightly.
"Senior Brother Xu..." Fei Qian called softly.
Xu Yue Wan didn't seem to hear anything. He just held the wooden tablet, his whole body was shaking, and muttered, "It's wrong... Why is it wrong... How can it be wrong..."
Kan Ze, who was beside Fei Qian, said worriedly: "Lord, Master, he hasn't had a good rest for three days. If this... continues like this..."
"Have you anything to eat?" Fei Qian asked.
"There is food... but not much..." Kan Ze said, "When it is brought to his mouth, he sometimes takes a bite and drinks a little, but he never sits down to eat properly..."
Fei Qian frowned, this was not the way to go. "It is the right way to relax and relax. It is not good to be so exhausted without rest..."
"My lord, this is a temporary confusion," Huang Xu said, "This is a common thing in the army. After getting out of the battle formation, he becomes confused and confused. If he is put to sleep for a while, he will probably be cured."
Fei Qian nodded, "You might as well give it a try."
Huang Xu held up his hands and was about to swing his arms forward to knock Xu Yue unconscious, but was stopped by Kan Ze on the side. "My lord, my lord! Please be merciful... I also know this method, but I don't dare to do it... just in case."
It hurts my mind, this..."
Fei Qian looked at Kan Ze, why did he feel that Kan Ze's attitude towards Xu Yue seemed to be better than his treatment?
But what Kan Ze said makes sense. After all, Xu Yue is not a military commander in the military academy. It would not be pretty if he really suffered a concussion.
"Come on, go to the Hundred Medical Center and boil some soothing medicine and bring it over! Go and come back as soon as possible!"
The soldiers on the side responded and hurried away.
There are many health-preserving prescriptions in traditional Chinese medicine. Although they may not have the sedative effect of Western medicine, the advantage is that they have fewer side effects, not to mention that this is the only method that can be used at the moment.
Sun offset.
"That's not right... Those who correct the new moon are calling it the beginning of the year..." Xu Yue was still mumbling, "Looking down closer... the sun is in the east and the moon is in the west, that's right... but why is it wrong?"
Fei Qian turned around and asked Kan Ze, "What does it mean to know that Senior Brother Xu is doing this?"
Kan Ze reported back: "Master said that there are differences in the twenty-four sections...it is very different from the sun and the moon, so it needs to be re-deduce..."
Fei Qian nodded.
Understood.
The arrival of Little Glacier not only drove farmers crazy, but also drove calendar scholars crazy.
The lunar calendar, based on the synodic changes of the moon phase cycle, stipulates that the length of a month is 29 or 30 days. Because the overall temperature in China was relatively warm during the three to four hundred years of the Han Dynasty, the earliest lunar calendar was calculated using the moon phases.
The crop maturity cycle, which stipulates that a year is divided into 12 lunar cycles, is called a year, and the year is when the grains are ripe. This lunar calendar guides agricultural farming and the corresponding 24 solar terms. Generally speaking, there is no big problem.
But after all, there is a time difference between the lunisolar and solar calendars, so the reason why Fei Qian's master Liu Hong re-established the calendar before was because of this. As time goes by, the difference between the lunar calendar and the solar calendar becomes more and more obvious, and now, it is
It became more prominent.
This is why Fei Qian attached great importance to the calendar and asked Xu Yue to start implementing the new calendar.
A ruler who cannot accurately guide his people to farm in a timely manner, or even has major calendar deviations, is a serious political crisis in any case.
Obviously, Xu Yue has problems in this regard...
And if Xu Yue can't solve this problem, it means that Fei Qian will have problems in this regard. Although the end of the Han Dynasty to the Jin Dynasty, and then to the Wuhu chaos in China, can be regarded as a relatively bad time period, but it can not be bad.
Some, it’s better not to be bad.
But now it seems that Xu Yue has fallen into a bottleneck and is stuck.
Among the twenty-four solar terms, the summer solstice and the winter solstice were the first two seasons to be determined due to their special characteristics. Even in ancient times, the winter solstice was the beginning of the year.
This is very easy to understand.
The twenty-four solar terms have nothing to do with the months of the lunar calendar, and are only closely linked to agriculture. Therefore, the temperature is now chaotic during the Little Ice Age, which has also caused calendar scholars to collapse...
Not long after, the soldiers galloped back and brought back a bag of decoction.
Huang Xu took it, then turned his head to listen to something, nodded, turned to Fei Qian's side, and whispered.
Fei Qian's eyes moved slightly, then he signaled Kan Ze to get the medicine, poured a bowl, and brought it to Xu Yue's mouth.
When people are subconscious, they are more willing to accept the approach of those close to them, and they are less likely to resist.
Maybe he was also thirsty. Xu Yue tilted his head, keeping his eyes on Rigui, and then took a few sips. He disliked the bowl that Kan Ze brought over and blocked his sight, so he pushed it away impatiently.
Kan Ze looked back at Fei Qian, who signaled that he wanted to feed him more.
Kan Ze found another opportunity and drank most of the Ningshen Decoction in his skin to Xu Yue.
Perhaps it was the effect of the decoction, or perhaps the body itself was exhausted. Not long after, Xu Yue's body began to shake, and then he fell down...
Kan Ze, who was well prepared, quickly stepped forward to support him, and then entered the room with Xu Yue, who had fallen asleep on his back.
Fei Qian stepped forward and picked up the wooden tablet that fell from Xu Yue's hand.
The wooden tablets are densely packed with numerical values and calculations, basically all about the length of the day and the time in years and months.
During the period of Emperor Wu of the Western Han Dynasty, the twenty-four solar terms had been included in the "Taichu Calendar" as a supplement to the calendar to guide farming. It was just the same as what Xu Yue had done before, using Tugui to measure the sun's shadow to determine the solar terms. Then it was used to determine the solar terms.
The length of the sun's shadow is equally divided into the years and months, and this is used to determine the twenty-four solar terms.
And here's the problem.
To put it simply, it is to use the straight to find the curve, to use the small to find the big, to use the finite to find the infinite. At this moment, among the entire Han Dynasty, there are only a handful of people who can study it.
number.
After all, not everyone can understand the difference between the sun and the earth, regardless of their shape or state of motion, between ellipses and circles, just like some trolls will say that piracy is also a copy. For scholars, how can it be considered stealing?
Fei Qian thought for a long time, and then something suddenly dawned on him.
The twenty-four solar terms established during the reign of Emperor Wu of the Han Dynasty were linked to the length of the shadow of Rigui. This method cannot be regarded as wrong. After all, the four major nodes, the spring and autumn equinoxes, the winter and summer solstice, are not wrong, but the other solar terms cannot be regarded as wrong.
Divided equally according to the length of the shadow...
This problem even affected for a long time. Finally, in order to solve this problem, the wise ancients added the changes of the sun to the lunar calendar based on the changes of the moon phases. This is the origin of the Chinese solar calendar, and summed up the twenty-four
Solar terms and intercalation methods are used to reconcile yin and yang. This progress is undoubtedly unprecedented, and it is also the reason why the lunar calendar can still accurately guide agricultural times after thousands of years. This fundamentally gives the lunar calendar endless vitality and allows it to be used in future generations.
What should I say?
The intersection angle between yellow and white? Perihelion and aphelion? Calculation formula of ellipse?
How can Xu Yue understand and accept it, and at the same time, there must be a statement that is consistent with the current situation and can also solve the current disconnect?
"Get a pen!"
Fei Qian took the pen in his hand, thought for a long time, and finally put it down...
"Gen, the hexagram of Northeast, is where everything ends and everything begins."
This is the Book of Changes, which tells the hexagrams.
"The solar terms of Zhuanghe are acquired. Therefore, the Gen hexagram returns to the Yin position."
This is acquired gossip.
"The sky spins, the earth spins, the stars move, the seasons change, everything has its destiny!"
This is the Big Dipper.
"The sun and moon are uncertain, so look for the stars!"
This is based on the Beidou to determine the twenty-four solar terms!
Seriously speaking, of course the position of the sun is used to determine the twenty-four solar terms, but many ancient astronomers did not have the sunglasses of later generations, many did not know how to protect themselves, and they were blinded for the cause of astronomy.
There are only a few, and the one closest to the sun's rotation coefficient is Beidou.
Observing Beidou at night is naturally more friendly than staring at the sun during the day...
Although Beidou will also cause speed changes due to other factors, it will generally not be a problem to use it for hundreds of years after it is determined...
After descending from Lishan Mountain and asking Kan Ze to take care of him and report back if anything happened, Fei Qian returned to Chang'an. Halfway there, he ordered: "Let Shi Yuan come and come!"
The latest news from carrier pigeons, something happened in Jingzhou!
