Chapter 668 Missing

"This is the spirit I see in you."

"This spirit is the treasure of Si Tianjian, so you cannot leave. You should accept the title of the first bachelor of Huangsong Polytechnic calmly to inspire future successors to follow your footsteps and continue to explore!

"

"Since the beginning of China, countless knowledge has been lost. The Han and Tang dynasties were continuous, and no one can understand the ancestor's "Zhushu". This kind of thing cannot be allowed to continue in our hands."

"So I thought of some ways to change the recording method of our knowledge, so that it no longer has the difficulty of being incomprehensible and having to be taught orally to understand."

"This is the basis for promoting our knowledge, so that we can attract more colleagues to contribute to this knowledge."

"But these are just trivial matters to you, and there are no restrictions. Because your knowledge does not require these things, you have gone ahead of us and reached a height that is difficult for us to reach."

"What we have to do is to translate your knowledge into something that everyone can understand and understand. So don't bear any burden, Mr. Wei. Those guys are treating you as their ancestor."

It should be!"

"You can count them with your eyes closed, are they still being reasonable?! Did someone say something weird? I'm going to investigate right now, and I can't kill him!"

Old Wei Pu burst into tears: "No, no, I thought the "Feng Yuan Li" was perfect, but the supervisor and Zhang Tianshi introduced precession so that it could be adjusted year by year. This method was already ahead of Lao'er, and it also solved the problem of Lao'er.

I have been confused for many years. You are more knowledgeable than me, but I am ashamed and dare not take up the post."

"Feng Yuan Calendar" takes the beginning of spring as New Year's Day, fixes the year with 365 days, the thirty-first day of the big month and the thirtieth day of the small month, and arranges the twenty-four solar terms at the end of the first ten days of each month and the beginning of the last ten days of each month. This is actually consistent with the calendar of later generations.

It is quite similar and is also the most advanced calendar today.

However, Su You and Zhang Tianshi took action to make this method more advanced. They carefully studied the two systems of the sun and the lunar system, using the tropic year to determine the year and the lunar calendar to determine the month and day. Although it is complicated, on the twenty-four solar terms, the ecliptic longitude and red are used.

Latitude is measured in degrees. The focus of the sun crossing the equator from south to north along the ecliptic is the vernal equinox. Every fifteen degrees of the ecliptic longitude is a solar term, a total of twenty-four solar terms. Every thirty degrees is a solar term, a total of twelve solar terms.

gas.

The day when the sun, moon and Bianjing are closest to a line and the month is between the sun and the earth is the new moon day, which is the first day of each month. It is said that "the new moon is used to divide the month every year."

If there is no Zhongqi in a month, a leap will be set.

To put it simply, the first step is to use the lunar calendar to determine the month. The new moon is the new moon, and the full moon is the fifteenth day. The period between two new moons is one month.

The second step is to use the sun to determine the solar terms. The longest day is the summer solstice and the shortest day is the winter solstice.

The third step is to take the month of winter solstice as November.

The fourth step is to combine the solar terms and months to see whether there is a leap month, a leap winter month, or a leap twelfth month.

The fifth step is to determine the first day of the first lunar month based on the winter month and whether there is a leap month.

Then cycle, every four years through leap months, the day counting error is adjusted, and the twenty-four solar terms, through precise calculation and measurement, ensure that they are not interfered by the day and month calculations, calculated based on the Yellow Longitude, and are accurately arranged where they should be

On a certain day, a certain time, a certain moment.

This calendar is actually not as accurate as the original "Feng Yuan Li" in counting days, but it takes more care of the living habits of the Song people.

In terms of solar terms, it is much more accurate than the original "Feng Yuan Li".

Because climate, plant growth, and sunlight are closely related, it is of great significance for guiding agricultural production.

There is also the new version of the "Feng Yuan Calendar", which is based on observations and makes fine-tuning of errors every year. This level shows that the new calendar has completely mastered the operating rules of the sun and the moon, and can guarantee that no matter how many years it goes on in the future

its accuracy.

Su You patiently explained: "You alone have done the basics. We are just adding bricks and mortar to make it more thorough and accurate. Now that the new calendar has been revised and perfected, I will ask the imperial court for your credit."

.How can you leave at this time?"

"Next, we will follow your line of thinking and calculate the solar and lunar eclipses that have occurred in history one by one. This project is also very large, but it is also very important. It plays a milestone role in exploring the historical chronology.

.”

In the history books of Chinese dynasties, there is a "Tianwen Zhi", which records special celestial phenomena.

Being able to accurately deduce the exact time of astronomical phenomena such as solar and lunar eclipses, the appearance of comets, and the entry of stars into the palace in the Central Plains in the past years can provide strong evidence for historical chronology. This will be the contribution of Neo-Confucianism to historical research.

significant contribution.

In the minds of the rulers of the dynasty, this item is probably more important than determining the twenty-four solar terms every year. Countless historical events, especially those that occurred in the three ancient generations, will need to be redefined and explained.

Wei Pu took Su You's hand and said: "I have been poor since childhood, living in a shrine, and doing divination as a profession. The "Chongtian Calendar" predicts that there will be a solar eclipse in July of the first year of Xining. This is wrong.

"

"If it were normal times, I wouldn't say anything. How could the new emperor make such a big mistake when he ascends the throne? So I wrote to Si Tianjian to correct the matter, and it turned out to be exactly what I said."

"Because of this, I have received your majesty's kindness. Instead of considering my disability as useless, I was admitted to the Si Tianjian to compile the "Feng Yuan Li"."

"Si Tianjian at that time was different from today. There was so much corruption that I had no help at all, so I had to perform the calculation alone. It took seven years to get the rough idea."

"After the prison judge arrived, he set up examinations to promote talents. In just two months, he revised and perfected the calendar. If I could have met the prison judge seven years ago, why would the "Feng Yuan Li" have been delayed so far? How could it have been delayed?

So far..."

The old man has also been suppressed for too long. The depression in his chest finally came out today. Tears were pouring from his blind eyes and he couldn't stop it no matter what.

Su You also had tears in his eyes, trying to comfort him. At this moment, Shen Kuo ran over quickly: "Shaobao, Your Majesty has an edict, asking you to go to the Privy Council immediately."

Su You was shocked: "Western thing?"

Now he is Jing Zhaoyin, and the Privy Council summoned him only because of his qualifications as a military officer in Shaanxi.

Shen Kuo also turned pale: "There are rumors in the capital that Wang Shao overthrew his army."

Su You couldn't help but feel dizzy: "How is that possible?!"

I, this butterfly, actually slapped away the historical ace of the Song Dynasty in conquering the Qing and Tang Dynasties?!

Arriving outside the door, the officials who were watching the book in Ke Zhengtang were already talking about it. Zhang Qi prepared his horse, and Tong Guan handed over to Su You: "Shaobao, the officials have summoned you."

Su You got on his horse and said, "Let's go!"

The three horses rushed outside the Privy Council. Su You threw the horse to Zhang Qi and asked Tong Guan: "Is the military report accurate?"

Tong Guan followed Su You and said, "The military report was sent by Lieutenant Guo. There has been no news from Wang Jinglue for more than a month."

Entering the northwest hall of Baihu Hall, in front of a huge sand table, Zhao Xu, Wang Anshi, Chen Shengzhi, Cai Ting and others were already discussing.

Wang Anshi saw Su You coming in: "Mingrun is here."

Su You held up his hands and said, "I have met your Majesty, my husband, your minister, and your deputy."

Cai Ting said: "This is not the time to be polite. Guo Kui reported that Prince Chun entered Lugu Mountain. Thirty days have passed and there has been no return. He was worried about the situation in Xihe, so he reported to the court."

Su You said: "Then I will read the military report first."

Cai Ting found the file and handed it to him. Su You read it at a glance and asked: "Where are the early military reports?"

Cai Ting dug out another pile of northwest memorials: "Here it is."

Su You read through them one by one, and the previous report was very clear. In June, Wang Shao reported that the soldiers were well maintained and were preparing to cross the Tao River again and occupy Kangle, Jiehe, Liujiachuan and other peripheral areas of Hezhou.

At the end of June, the first step of the strategic goal was achieved. Wang Shao continued to march and occupied Pingqiang City and Xiangzi City again.

By mid-July, Wang Shao had been suspending his offensive and hoarding supplies in Xiangzi City. At the same time, he continued to consolidate the peripheral areas of Hezhou and once again formed an encirclement of Hezhou.

At this point, Wang Shao's steps are exactly the same as at the beginning of the year. It seems that he wants to copy the steps he has taken.
