Chapter 731 Solar Calendar

Li Chunfeng didn't beat around the bush, and directly explained the purpose of coming here.

Knowing what happened, Yue Shan shook his head helplessly. He had expected this kind of thing a long time ago, so he didn't find it strange. Anti-intellectual behavior existed in any era.

It is not uncommon to oppose the repair of telecommunications base stations in previous lives, thinking that radiation will kill people. There are even people who think that wifi signals have radiation and ask other people to turn off wifi.

This has nothing to do with whether or not you have read a book. It is purely an abnormal brain circuit, which cannot be rescued by education.

Using the topic of feng shui and luck, Li Chunfeng directed the conversation to astronomy and astrology.He said that he was planning to compile a book on astrology by summarizing the experience of his predecessors, hoping to get Yue Shan's guidance.

Yue Shan is not surprised at all that he has this idea, the more talented a person is, the more he wants to publish a book, besides, Li Chunfeng has done such a thing in history.

But he was asking the wrong person.Yue Shan really didn't know much about astronomy and astrology, he couldn't even tell the direction by looking at the Big Dipper, let alone other things.

However, Li Chunfeng didn't believe it, let alone him, no one in the world would believe him.The number one magician in the Tang Dynasty doesn't understand astronomy and astrology, so who is he to lie to?

But when it comes to this matter, Yue Shan really has a plan to cooperate with Li Chunfeng, so he said: "I don't dare to ask for advice, but I do have one thing I want to trouble Tai Shiling."

Li Chunfeng said: "It's my honor, please tell Duke Xia if you have any orders."

Yue Shan didn't say it directly, but asked, "What's your opinion on the current calendar?"

Li Chunfeng asked suspiciously: "I don't know which aspect you are referring to?"

The question just now was really too general, Yue Shan thought for a while and added: "Accuracy."

Li Chunfeng nodded, thought for a while and said, "The calendar is based on the observations of the moon and the waning of the predecessors. The pre-Qin period used October as the beginning of the year. When Emperor Wu of the Han Dynasty re-calibrated and promulgated the Taichu calendar, it was stipulated that the first month is the beginning of the year..."

"However, the change of the moon's waxing and waning is not constant, so there is a big error between the calendar and the actual weekly number of days, so the leap month or leap week is used to adjust the precession..."

Before the Tang Dynasty, there was a leap week. During the Tang Dynasty, the leap week was abolished and the leap month was retained. Since then, the seven leaps in 19 years have been handed down.

After listening to him, Yue Shan said: "If I remember correctly, according to the current calendar, leap months and leap weeks are not counted, it should be 350 five days in a big year and 350 four days in a small year. I don't know if that's right?"

"Yes." Li Chunfeng replied.

"Then I can tell you that this number of days is wrong. According to the number of cycles in the sky, a year should be 360 ​​five days and 360 six days." Yue Shan said seriously.

"Wow." Li Chunfeng knocked down the teacup on the table with a shake of his hand, but he didn't care about being rude at all, and hurriedly asked: "Duke Xia is serious?"

Yue Shan smiled and said, "Really. Our current calendar is based on the waxing and waning of the moon, which can be called a lunar calendar. In fact, the most accurate calendar is calculated based on the sun, and the annual error does not exceed 10 minutes."

"The solar calendar?" Li Chunfeng muttered to himself for a long time, then got up and solemnly bowed: "I also ask Duke Xia to give me some guidance."

Yue Shan accepted his great gift calmly, and said: "I don't know how to observe the movement of the sun to determine the calendar, but I can tell you the law of the movement of Qiyao, and you can summarize it yourself."

Hearing this, Li Chunfeng was not only not disappointed, but excitedly bowed to Yueshan again and again.

It is better to teach a man to fish than to give him a fish. If the method of observing the sun is fish, then the law of Qiyao's operation is 'fishing'.

If he mastered the laws of Qiyao's movement, he would not only learn to observe the sun, but he might have to rewrite the entire history of astrology, so that he would not be excited.

Yue Shan took him to his study, took out a painting and spread it on the table.

Seeing this painting, Li Chunfeng felt like getting an electric shock, trembling all over with excitement.

It turned out that this painting was the most famous picture in the geography books of junior high school in the previous life-the diagram of the eight planets in the solar system.

After he recovered from the excitement, Yue Shan pointed to the painting and said: "This is the sun, and all the stars revolve around it. These planets are water, gold, earth, fire, wood, and earth from near to far..."

"The earth star is the world we live in, and the moon revolves around the earth star. The way and route of these planets are roughly like this..."

As a liberal arts student, Yue Shan really knows very little about astronomy and geography. This map of the eight planets in the solar system is one of the few things he can still remember.

But this very common picture in the previous life is a treasure for Li Chunfeng, an epoch-making truth.

It gave him a feeling that the world is like this, and all kinds of astronomical phenomena that he couldn't figure out before also had answers.

Why there are four seasons, why there is day and night, why there is a solar eclipse, why there is a lunar eclipse, what is the broom star...

But at the same time, this picture is also a complete subversion of the knowledge he has learned before.

If the principle of the occurrence of various astronomical phenomena is really as drawn in this picture, then the so-called providence and so-called astrology...

He no longer dared to think deeply.

"Duke Xia, if this... this picture is spread, it may cause chaos in the world." He said excitedly and hesitantly.

"I know, so I never told outsiders. You are the first to know. I believe you will not spread the word." Yue Shan said.

Li Chunfeng looked serious, and said solemnly: "Thank you for your trust, I swear I will never reveal a word to anyone."

Yue Shan said: "No need to swear, I can still trust your character. Let's go back to the original topic, now you know how to observe the sun and formulate the calendar?"

Li Chunfeng nodded and said: "I already have an idea, but it still needs to be verified."

In fact, this once again touched Yueshan's knowledge blind spot. The Gregorian calendar in the previous life used the Western Gregorian calendar, and the lunar calendar used the lunar calendar.

Many people subconsciously think that the Gregorian calendar is something from the West, while the lunar calendar, that is, the lunar calendar, is handed down from ancient China.

In fact, this is not the case. Telling the real situation can make everyone proud, but it will also make many people depressed.

What I am proud of is that in ancient China, there was a deep study of the solar calendar. For example, the celestial stems and earthly branches are summed up according to the laws of the sun's movement, which is regarded as the solar calendar.

It's just that everyone is used to using the Taichu calendar, and the solar calendar is only used when professionals study astronomy and astrology.

What is frustrating is that the progress of Chinese civilization in modern history has been overtaken by the West, and it is also lagging behind in astronomy and astrology.

The lunar calendar currently in use was actually formulated by Manchu Qing invited Western astronomy experts to re-study, and it is no longer a traditional lunar calendar in the true sense.

However, during the Tang Dynasty, the Taichu calendar was still the most accurate calendar in the world at this time, and the celestial stems and earthly branches were the most in-depth research on the solar calendar theory at this time.

Li Chunfeng, who is a magician and an astronomer, naturally understands some of the methods of observing the sun. With the diagram of the eight planets, he has ten levels to make me work out the solar calendar.

When he said that he had an idea, he didn't mean to be arrogant, but he really did.

Yue Shan said with satisfaction: "That's good. Our sage Wen Tao Wu Lue aims to surpass all predecessors and create an incomparable achievement. A few years ago, we changed the way of counting years and re-established weights and measures for this purpose."

"If you can study the solar calendar, it will not only benefit the people, but also make the saints value you more. Then you can use the power of the imperial court to write books on astronomy and astrology."

"Thank you Lord Xia for teaching me, I know what to do." Li Chunfeng said respectfully.

At this time, he was very excited, which could not be described in words.He has never been married, but presumably the wedding night in the bridal chamber is nothing more than that.

He came to Yue Shan to complete the characters given by the court, and he mentioned his writing a book by the way, to see if he could get some pointers.

I don't have much expectation on whether Yue Shan is willing to give him advice, this kind of supernatural stuff is sometimes a dead end.

What is utter learning?It is the kind of knowledge that even children may not be able to pass on, the kind that will be lost once the person who masters it dies.

Yue Shan has been working hard to get rid of his status as a child of a fairy these years, and he has never given orders to anyone in recent years.It can be said that apart from helping the royal family deal with two crises, he has never made a move.

So no matter from which aspect, the probability of pointing him is not high.

However, to his surprise, Yue Shan not only gave him advice, but also had such earth-shattering knowledge when he made a move.

Although this is just a picture, the content on it can subvert the entire astronomy and astrology.

Li Chunfeng was also full of gratitude to Yue Shan in his heart, and when he said goodbye, he even acted as a half-teacher.

While Yue Shan said that he didn't dare to act, he was still very relieved in his heart.Although this picture is very common in later generations and belongs to common sense, it is the truth in this era.

If Li Chunfeng accepts it with peace of mind and doesn't express anything, he won't be angry, but he will stay away from this person and try not to deal with him in the future.

After returning to Beijing, Li Chunfeng immediately entered the palace to meet Li Shimin.

Li Shimin was very surprised at his arrival, and asking him to visit Yue Shan's house was just a formality.Tomorrow morning, it will be finished after a public report, why did you go to the palace to ask for an interview in private?

Did something unexpected happen?With such doubts in mind, he interviewed Li Chunfeng.

Li Chunfeng first reported the mission situation, naturally there is no problem, the train will not affect Feng Shui and luck.

Immediately afterwards, he said the real purpose of seeking a meeting, to study the solar calendar.

And what Yue Shan told him, the solar calendar is more accurate, the actual number of days in a year is 360 five days, the error is only about three hours, a leap day every four years is enough...

Anyway, except for the map of the eight planets in the solar system, which was covered by him, he said everything else.

The reason why he didn't say it was not because he wanted to hide it from Li Shimin, but because in his opinion, this kind of unique knowledge could not be easily told to others, even the emperor was no exception.Yue Shan was already very grateful for telling him, how could he reveal it easily.

Even if Yue Shan reveals the matter himself in the future, he is not afraid of Li Shimin being held accountable.

Still the same sentence, this is a unique knowledge, everyone like Yue Shan can teach it to whoever he wants, he can't say it.

Besides, this is the rule of this era, and Li Shimin will not condemn him because of this incident.

Li Shimin was also very pleasantly surprised when he learned about this. Emperor Wu of Han himself was his goal to surpass, and since he wanted to surpass, it was all-round.

The current calendar is the "Taichu Calendar" revised by Emperor Wu of the Han Dynasty, so I will replace you with a more accurate and advanced calendar.

And there is another sentence that is deep in his heart, the Taichu calendar is a lunar calendar, what Yue Shan and Li Chunfeng are talking about is a solar calendar, the sun must be greater than the moon.

So he immediately ordered Li Chunfeng to study the solar calendar with all his strength, asking for money and things for things and people for people.

Li Chunfeng, who had achieved his goal, stood up and resigned. After returning to the Taishi Bureau, he immediately became anxious for the elite talents under him, and announced that he would study the solar calendar and formulate a more standard calendar.

As soon as this news came out, not only the Taishi Bureau was shocked, but the entire astronomical and astrological circle was shocked.

Anyone who has done some research on this aspect has rushed to the capital to inquire about the specific situation.

Li Chunfeng was naturally very happy about this, met them one by one, and invited them to join in.In order to show his sincerity, he also revealed a little bit of his own research.

The rest of the matter is simple. The knowledge beyond the times has convinced everyone, and the Taishi Bureau no longer has to worry about losing its manpower.

In fact, not many people came. In ancient astronomy and astrology, prophecy and taboo were equated. Although the imperial court did not order to prohibit it, it was forbidden to spread it in private.

It can be said that there are very few people who study this kind of knowledge, and everyone regards their own knowledge as a treasure, for fear of being learned by others.

Li Chunfeng used a solar calendar and some knowledge deduced from the eight planetary charts to bring these people together, which greatly promoted the communication of the entire school.

It laid a good foundation for the further development of astronomy and astrology.

Of course, this is all later, so let's not mention it for now.

In addition, after Yue Shan sent Li Chunfeng away, he continued to sort out the materials at home. Li Shimin excused that he missed his grandson and asked people to send rewards to his home several times, and asked when they would bring the child into the palace for him to see.

Yue Shan knew in his heart that it was false to think about his grandson, and it was true to urge him to enter the palace to talk about the change of dynasty.

Every time he gives the same answer, recently he is sorting out the materials, and he will go when he is done.

Li Shimin could bear it, and never forcibly called him into the palace. He just urged him from the side under the guise of missing his grandson every now and then, expressing his urgency.

Others don't know Li Shimin's real intention. He rewarded Yueshan's children with a large amount of property after seeing the emperor every three days or so.Whenever there is any good thing in the palace, a copy will be given to them immediately.

Everyone thought that he really loved these two grandchildren, and many people were jealous.Many ministers even hinted that his behavior was too much, which could easily cause conflicts.

Li Shimin accepted the advice sincerely, but he still should do what he should do later.

After almost half a month, I finally sorted out the summary of the part that can be revealed to Li Shimin.

When the gift from the palace to the child was delivered to the mansion again, he told the envoys to enter the palace tomorrow.
