Chapter 2025 A broken mirror is hard to reconcile, the yin and yang calendar
『The envoy has returned home! 』
With a loud announcement, everyone in the Liu Mansion started to move. The servant hurriedly sorted Liu Biao''s usual utensils, then reached out and touched the corner of the table to confirm that there was no dust before giving up, and hurriedly added some to the refreshing drink warmed on the small red clay stove. Fire, and when I heard a loud grunt, I quickly took it down again, put it in the warm cover and waited.
Several maidservants in the inner courtyard greeted Liu Biao at the gate of the courtyard. When they saw Liu Biao, they went up to the left and right to gently support him, then turned into the screen, changed the red and black crown clothes, and changed into casual clothes.
『Where is Conger? 』
Liu Biao asked.
If you look at it from a distance, Liu Biao''s face is rosy and has an extraordinary bearing, but if you get close, you can see that the thick powder on Liu Biao''s face has cracked a lot when he speaks and moves, and some dust falls with the words .
Today is Wangri, and according to the usual practice, he is going to meet with the officials of Jingzhou. In order not to let people see his sick face, Liu Biao put on thicker powder than usual.
Asian magic has been passed down since ancient times.
At this time, Liu Cong was in the inner study, feeling uneasy. On a normal day, he would still have the air of a nobleman, but right now, there is no grace at all, walking around the study with his hands behind his back, unable to stop no matter what.
It''s no wonder he, at this moment, even a fool knows something is wrong...
Needless to say, the Liu guards standing outside the study have already explained some problems.
The sound of noise came from the outer courtyard, and after a short while, someone came to the study, cupped his hands and said, "Young master, the king is here to call you." 』
Liu Cong ran out in a hurry, and he breathed a sigh of relief after seeing Liu Biao.
『Father…』
Liu Cong bowed his head to see him.
"Come in! 』
Liu Biao sat in an even position. Don''t look at Liu Chao who is sitting steadily now, but various thoughts are fluctuating in his heart.
『Father…』
Liu Cong came to the side and said something in a low voice.
『Sit down…』 Liu Biao glanced at Liu Cong.
"Father..." Liu Cong spoke again.
Liu Biao frowned, and the powder on his face fell down again, "I said, sit down!" 』
『Oh, oh…』Liu Cong sat down now.
Ever since Cai''s plot, Liu Biao has already imprisoned Cai in the backyard, and the entire mansion is basically controlled by Liu''s guards, and even with Cai Mao, most of the military power has been eliminated.
As for why Liu Biao didn’t completely kill the Cai clan at that time, and kept it for the New Year, could it be that Liu Biao’s head was showing off and he was forcibly demoted by the horse monkey?
it''s actually really easy.
The Cai family is intertwined and deeply rooted in Jingxiang. Liu Biao''s wife is the Cai family, and Liu Cong''s wife is also the Cai family. How many other families have wives who are also the Cai family? If the Cai family had been directly killed at that time, wouldn''t the Hussar general who had become involved with the Cai family have a reason to go south? What if the hussars really took Liu Qi south? Then whether it is Pang Degong or Huang Chengyan, as long as one of them really stands up, believe it or not, Liu Biao may not even be able to control Xiangyang!
Now that Cai Hao was slowly squeezed out of the army, and the power in the army fell into the hands of Gan Ning, Liu Biao didn''t feel cold in his back, and he had the courage to attack Cai.
What? Cao Cao killed Cai Mao?
Ha, that''s Romance of the Three Kingdoms.
The real history is "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", and then Cai Mao was granted two thousand stones, and he was granted the title of Marquis of Hanyang Pavilion until he died of old age. There was nothing like Zhou Yu at all. thing.
Then why Liu Biao started plotting the Cai family again now? After all, a broken mirror is hard to reunite, and cracks have already formed, so is it possible to restore it to its original appearance?
Liu Biao knew this, and so did Cai Mao.
Also, time has changed...
It’s like those big tigers in the later generations. When they are entrenched in the place and roaring on the hills, no one hears, no one knows, no one reports? Hehe, but why not deal with it directly, and have to wait until the fire is ready before serving the pot?
So Liu Biao thinks that now is the time to fire.
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 and silver jewelry, valuables, 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 are all planning to go to Chang''an.
Then, Sanfu in Guanzhong, north of Dahe, Jizhou and Qingzhou, are subject to natural disasters!
Fei Qian asked his soldiers to assist in farming and rescue Zhuang He...
Cao Cao is busy in Yecheng to win over the people of Jizhou gentry...
Everyone is busy, this is good. After tidying up the Cai family, it will be in time for the autumn harvest, and then I will be busy again. After the end of autumn, Liu Biao will be able to stabilize Jing Xiang, and then pass the position to Liu Cong first, and help him while he is still breathing. Help, let Liu Cong save as much money as possible...
As for the future, it depends on Liu Cong. So Liu Biao is now taking Liu Cong by his side, which can be regarded as teaching by precept and example.
So, is there a better time than now?
Coupled with Zhang Ji''s escape, it was tantamount to pressing the last straw to collapse. If Zhang Ji and Zhang Zhongjing were around, Liu Biao still had some hopes of dragging on, but now only relying on the prescription left by Zhang Ji, without timely acupuncture and moxibustion conditioning and increasing or decreasing the dosage, how long can Liu Biao''s broken body last?
Jingxiang is Jingxiang of the Liu family, not the Cai family!
Before I can move, I want to clean up all the thorns for Liu Cong!
Liu Biao deliberately exposed his body today, using his body as bait in an attempt to catch Cai Mao. He couldn''t believe that Cai Mao hadn''t read that "suicide note", he just wrote it for Cai Mao!
But the question is, why didn''t Cai Mao do anything today?
『Urgent military report! 』
Suddenly a loud cry broke the silence.
『There is a thief in Yunmengze, who calls himself General Huxiao, and has a crowd of one hundred thousand, marching towards Jiangling! 』
...(⊙_⊙;)...
Chang''an.
Lishan, the place to observe astronomy.
A cooing bird flew across the sky with a whirring sound. 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 hands, "Since we have already reached the bottom of the mountain, we are not in a hurry. Go back and talk about it. 』
Under Lishan Mountain, Kan Ze has long been waiting.
Fei Qian came here, naturally there are some things.
What is madness and obsession? When Fei Qian met Xu Yue, he understood.
Xu Yue, with disheveled hair and disheveled appearance, was completely in a state of embarrassment. He didn''t have the posture of a nobleman at all. His clothes were disheveled, and he was staring at the Tugui scale with his buttocks pouted, unaware that Fei Qian had come to him.
Huang Xu frowned, and was about to step forward, but was stopped by Fei Qian.
Fei Qian saw Xu Yue''s concentration and obliviousness to everything, so he simply stood back and motioned not to disturb Xu Yue and others.
For a nation, some people stare at their feet, and some people look up at the starry sky. Only then can this nation have hope.
For the early Chinese people, looking up at the starry sky was basically a relatively basic exploration of the transformation of the sun, moon, and stars.
Basic, but not original.
The cultural inheritance of the nomadic people is relatively lacking, and it is naturally difficult to establish any connection between the sun, the moon, the stars and the livestock. As for the farming-based nation, because they pay special attention to the weather and weather, how to determine the season according to the time, and a series of related agricultural activities guidelines, such as temperature, water flow, sun and moon rise and fall, etc., have become the key points of agricultural farming. lifeline.
In this process, because the moon is closer to the ground, the cycle of change is very obvious, so almost all farming peoples with ancient cultures, such as ancient Egypt, Babylon, ancient India, ancient Greece, etc., all adopted this moon phase The calendar formulated by the laws of the lunar calendar, that is, the lunar calendar.
Fei Qian has always been thinking that ancient China is a lunar calendar, that is, a calendar based on the moon, but in fact, it is not like this...
As the only ancient civilization that has continued to future generations, the calendar of the Han nationality has also withstood the test of time under the rotation of the sun and the moon for thousands of years. The Han calendar used by later generations was said to have been created in the Xia Dynasty, so it was called the Xia calendar, and it was not renamed the lunar calendar until modern times. Because the moon and the sun are not synchronized, and the measurement methods of ancient people are not very accurate, there are often some large deviations. In order to make up for this problem, the concept of the solar calendar is incorporated, that is, according to the sun. The calendar of temperature changes. So to be precise, the lunar calendar of later generations is actually a yin-yang calendar mixed with some content of the solar calendar based on the changes of the moon phases in order to improve the accuracy of farming.
The Han Dynasty was the beginning of these calendars, and even the chronology of the heavenly stems and earthly branches that lasted for thousands of years and was still used by later generations also started from this era...
"That''s not right..." Xu Yue frowned, his eyes fixed on Tugui, and then he grabbed the records on the wooden tablet beside him to calculate, "It''s not right...how could it be wrong...it''s not right... 』
Fei Qian sighed slightly.
"Brother Xu..." Fei Qian called softly.
Xu Yue seemed to have never heard of it, just holding the wooden tablet, his whole body trembling, muttering, "It''s not right...why it''s not right...how can it be wrong..."
Kan Ze, who was beside Fei Qian, said worriedly: "My lord, Master, he hasn''t had a good rest for three days. If this... continues..."
『Did you eat anything? ’ Fei Qian asked.
『There is food...but not much...』 Kan Ze said, "Sometimes he would take a bite and drink some of the food that was brought to his mouth, but he didn’t sit down and eat it well..."
Fei Qian frowned, this is not an option. "There is tension and relaxation, which is the right way. It''s not good if you don''t rest like this..."
『My lord, this is a temporary loss of mind,』 Huang Xu said, 『It is also a common thing in the army. After leaving the battle line, it is chaotic and unclear. Let it sleep for a while, and it will probably be fine. 』
Fei Qian nodded, "You might as well try it. 』
Huang Xu clasped his hands, and was about to knock Xu Yue unconscious with his arms swung, but was stopped by Kan Ze beside him. "My lord, my lord! Be merciful... I know this method, but I dare not move... If it hurts my mind, this...』
Fei Qian looked at Kan Ze, why did he feel that Kan Ze treated Xu Yue better than he treated himself?
But what Kan Ze said is also reasonable. After all, Xu Yue is not a general in a military school, so it is not beautiful to really have a concussion.
『Come here, go to the Hundred Medical Center, cook some soothing soup and bring it here! Hurry up! 』
The soldiers on the side responded and rushed away.
There are many health-preserving prescriptions in Chinese medicine. Although they may not have the sedative effect of Western medicine, the advantage is that they have less side effects, not to mention that this is the only way to use it at the moment.
Sun offset.
『It’s not right... correcting the new moon, it’s the beginning of the year...』 Xu Yue was still muttering, "Looking up and down...the sun is in the east and the moon is in the west, that’s right...but why is it wrong? 』
Fei Qian turned his head and asked Kan Ze, "Knowing what Senior Brother Xu is doing?" 』
Kan Ze replied: "Master said that there are differences in the twenty-four festivals...the difference between the sun and the moon is huge, so it needs to be deduced again..."
Fei Qian nodded.
Understood.
The arrival of the Little Ice River not only drove the farmers crazy, but also the calendar scholars.
The lunar calendar, based on the synodic month change of the lunar phase cycle, stipulates that the length of a month is 29 or 30 days. Because during the three or four hundred years of the Han Dynasty, the overall temperature in China was relatively warm, so the earliest lunar calendar used the phases of the moon to calculate the maturity cycle of crops, that is, it was stipulated that a year was divided into 12 wangshuo cycles, called years, years, and valleys. Cooking also, using the lunar calendar to guide agricultural cultivation and the corresponding twenty-four solar terms, is generally not a big problem.
But after all, there is a time difference between the lunar calendar and the solar calendar, so Fei Qian''s master Liu Hong re-enacted the calendar because of this. As time goes by, the difference between the lunar calendar and the solar calendar becomes more and more obvious. more prominent.
This is also the reason why Fei Qian attached great importance to the calendar and made Xu Yue start to implement the new calendar.
A ruler who cannot accurately guide the people under his rule to cultivate in a timely manner, or even has a major calendar deviation, is a serious political crisis in any case.
Obviously, Xu Yue has a problem in this aspect...
And if Xu Yue can''t solve this problem well, it means that there will be problems in Fei potential. Although it can be regarded as a relatively bad time period from the end of the Han Dynasty to the Jin Dynasty, and then to Wuhuluanhua, it is better not to be bad if it is not bad.
It just looks like Xu Yue is stuck in a bottleneck.
Among the twenty-four solar terms, because of the particularity of the summer solstice and winter solstice, they are the first two seasons to be determined. 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, but are only closely linked to agriculture, so now, the temperature in the Little Ice Age is disordered, and even the calendar scholars have collapsed...
Not long after, the soldiers galloped back and brought back a skin of decoction.
Huang Xu took it, then turned his head to listen to something, then nodded, turned his head to Fei Qian''s side, and recounted it softly.
Fei Qian''s eyes moved slightly, and then motioned for Kan Ze to take 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 close people, and they are less likely to have any resistance.
Maybe he was also thirsty, Xu Yue tilted his head, still keeping his eyes on Rigui, and after taking a few sips, he disliked the bowl brought by Kan Ze and blocked his sight, and pushed away impatiently.
Kan Ze turned his head to look at Fei Qian, and Fei Qian motioned for him to feed again.
Kan Ze took another chance and gave Xu Yue to drink most of the Ningshen decoction in the skin.
Maybe it was the effect of the soup, or maybe the body itself was exhausted. After a while, Xu Yue''s body began to shake, and then fell down...
Kan Ze, who had been prepared for a long time, stepped forward to help him, and then passed out Xu Yue, who was carrying his burden on his back, and entered the room.
Fei Qian stepped forward and picked up the wooden tablet that had fallen from Xu Yue''s hand.
On the wooden tablet, there are dense numbers and calculations, basically all about the length of the day and the time of the year and month.
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 calendar supplement to guide farming. It''s just the same as what Xu Yue did before, using Tugui to measure the sun shadow to determine the solar terms. Then divide the length of the sun''s shadow and the year and month equally to determine the twenty-four solar terms.
And that''s where the problem lies.
To put it simply, it is to seek curvature from the straight, seek the large from the small, and seek the infinite from the finite. At this moment, among the entire big man, there are only a handful of people who can study this kind of astronomical and mathematical problems. number.
After all, not everyone can understand that the difference between the sun and the earth, whether in shape or in motion, is the difference between an ellipse and a circle, just like some savages will say that pirated copies are also copies.
Fei Qian thought for a long time, and then suddenly realized.
The twenty-four solar terms established at the time of Emperor Wu of the Han Dynasty were linked to the length of Rigui''s shadow. This method cannot be regarded as wrong. After all, there is nothing wrong with the four major nodes, the vernal equinox, autumnal equinox, winter solstice and summer solstice, but other solar terms cannot. Evenly divided according to the length of the shadow...
This problem has 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 Gregorian calendar, and summed up the twenty-four Solar terms and intercalation method to reconcile yin and yang. This kind of progress is undoubtedly unprecedented, and it is also the foundation of the lunar calendar that can still accurately guide the farming time after thousands of years, which fundamentally gives the lunar calendar an endless stream of vitality and enables it to be used in future generations.
How should I say it?
Yellow and white intersection? Nearest point and farthest point? Ellipse calculation formula?
How can Xu Yue understand and accept it, but also must have a statement that conforms to the status quo and can also solve the out-of-touch current season?
『Get your pen! 』
Fei Qian held a pen in his hand, pondered for a long time, and finally wrote...
『Gen, the hexagram of the Northeast, all things come to an end and come to a beginning. 』
This is the Book of Changes, which is said to be passed on by hexagrams.
『The solar term of Zhuanghe is acquired the day after tomorrow. Therefore, the hexagram of Gen belongs to the position of Yin. 』
This is acquired gossip.
『The sky spins, the earth spins, the stars move, and the seasons change, there are definite numbers! 』
This is the Big Dipper.
『The sun and the moon are uncertain, take the stars! 』
This is to determine the twenty-four solar terms with the Beidou!
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 those who were blind for the cause of astronomy are not here. There are a few, and the one closest to the sun''s rotation coefficient is the Big Dipper.
Observing the Big Dipper at night is naturally more friendly than staring at the sun during the day...
Although Beidou will also cause speed changes due to some other factors, it will not be a problem to use it for hundreds of years after it is confirmed...
Going down Mount Li, he gave Kan Ze Haosheng to take care of him. If there were any accidents, he came back to report, and then Fei Qian returned to Chang''an. On the way, he ordered: "Let Shi Yuan come!" 』
The latest news from the carrier pigeon, Jingzhou, something happened!
