It's already nine o'clock in the evening in New York, but everyone's time difference is exactly the time of the day, and the biological clocks are not reversed.

Mr. Chen systematically discussed the meaning, characteristics, previous astronomical phenomena, various astronomical masters and their main ideas in detail, four books of 1.7 million words, Xu Le really admired!

Ancient Chinese astronomy was mainly for the service of the autocratic imperial court, and its functions were mainly twofold: one was to divinate the good fortune and evil for the autocratic imperial court, and predict good fortune and misfortune; The second is to compile the calendar, the calendar is helpful for agricultural production, but when the imperial court compiles the calendar, it also has the meaning of promoting imperial power.

In China, astronomy could only be studied by the royal family. In ancient China, ordinary people were forbidden to study astronomy, mainly because they were afraid that the people would rebel in the name of celestial phenomena. In ancient China, complicity in the crime of private astronomy was punishable by death.

The ancient Chinese calendar was extremely developed, and the time of the calendar was a symbol of imperial power. Since the Qin and Han dynasties, there have been more than 100 calendars. The ancient astronomical records of China were the richest and most systematic in the world at that time. In the fourteenth year of Lu Wengong (613 BC), the record of Halley's comet appeared in the Spring and Autumn Period, which is the earliest record in China; By the second year of Xuantong in the Qing Dynasty (1910), the history books recorded the appearance of Halley's Comet as many as three times. The Chinese believe that the comet represents a disaster, but they do not know that the three times recorded are the same comet.

The Chinese people formed a complete set of theoretical systems in astronomical divination. It also had an important impact on the current politics of the time. Although there is no understanding of the universe by establishing a mathematical system of the universe as the ancient Greeks did. However, through a series of sophisticated astronomical instruments such as the armillary sphere, the armillary theory and the celestial sphere theory were proposed. This was much more advanced than the geocentric theory that prevailed in the West at that time.

The unity of heaven and man is based on long-term observation of celestial phenomena. This theory has long been dominant in traditional Chinese culture. And the resulting Chongtian culture is unique in the world. The Chinese people studied the universe for practical purposes such as divination and calendaring, and did not study the universe purely from the scientific perspective of understanding the universe and exploring the laws of the universe like Westerners.

Among them, the astronomical history records in detail the "Zhongkang solar eclipse, the five stars are wrong, the stars fall like rain in the night, the two days rise together, the earliest determination of the yellow and red angles, and the measurement of the vernal equinox, the earliest date of Halley's Comet, the record of novas, etc.;

In the second century B.C., the Records of the Heavenly Officials recorded the celestial phenomena in detail. In the second year of Emperor Hui of the Han Dynasty (193 years ago), there was "the northeast of the sky, more than ten zhang wide; "In August of the first two years of Emperor Jing of the Han Dynasty (155 years ago), Yingfu retrograde guarded the North Star, the moon rose in the North Star, and the stars of the year retrograde in the Heavenly Court.

The overall astronomical history that has been written until the Qing Dynasty can be described as a brilliant masterpiece!

Xu Le recalled some things while corresponding to the things that happened at the time, basically there were major events, but it was also written that Zhongkang's solar eclipse may be wrong, either the record is wrong or the time is not right at all, Xu Le suddenly said to Professor Zong, "Professor Zong, I don't think it's right", Professor Zong suddenly heard Xu Le say in front, "What's wrong"?

"Regardless of whether the book is forged or not, at least the description of the things in the book should be true, and the difference of many years can be determined against that time, so it should be the earliest in the world, right?"

And Xu Le knew what might have happened, from a thousand years ago, his grandmother left, and it happened to be around two thousand BC, something must have happened at that point in time, it is definitely a so-called violation of current science, because according to the saying at the time, even if there was a lunar eclipse, it would not be seen in Huaxia, "Professor Zong, Professor Qin, have you ever thought about a question, if the Zhongkang solar eclipse really happened, but Westerners say that we can't see it, then is there another possibility? That is, is the territory of Great Xia large enough?"

Xu Le carried Guan Mu and drew a larger circle, "For example, is it true that Ai Ji is also ours?" Can it be said that the "Classic of Mountains and Seas" really records the whole world"?

The two professors were stunned by Xu Le's words, and another person who was also an astronomical person was also thinking!

Everyone stopped talking, "You're done with it"?

Professor Zong suddenly asked, Xu Le nodded, "I'm done!"

"Huh"?

"Ahh

"Haha", everyone laughed, and they will never remember with Xu Lebi in the future, and now everyone understands why this kid can produce things, he really doesn't sleep, and his memory is super good!

"The books I brought along the way are all for you", Professor Zong said helplessly, "Don't, Professor Zong, this set will be given to me, your set of astronomical calculations can be given to me, and the rest will not be forgotten", Xu Le hurriedly said!

Xu Le met that the person in charge of the customs was a man, looking at the brown skin, Xu Le looked at him, "You are a cadre in Huaxia"?

Xu Le nodded, "Fake, right?"

Xu Le shook his head again, "Do you speak English?"

Xu Le nodded again!

"Do you have relatives here"?

Xu Le shook his head again!

He shook his head and nodded amiably all the time, and finally made the customs officer laugh, "Pass"!

“Thank you”！

Xu Le waved his hand and jumped off the customs officer!

Xu Le waited for everyone to come out, and then followed behind Mr. Hou, looking at this known as the world's busiest chicken farm, it seems that it is indeed the stronger Anchorage chicken farm over there than Las, but it is not as new as Huaxia, of course, this has been running for a long time, Xu Le looked at the super-large electronic screen, looking at the flight codes of the planes that are waiting for entry and exit one by one, basically every one or two minutes, I can't help but smack my tongue, it's really amazing, everyone is waiting for luggage, Xu Le opened his mobile phone, First made a call to my mother, it was exactly nine o'clock in the day, Xu Le couldn't dial out, so he remembered that he had to add the country code and the area code of the territory, and then dialed it again, and finally passed for more than ten seconds, without ringing three times, and it was connected, and his mother answered the phone, Xu Le said directly, "Mom, I'm here, Xiaobai and I are very good, don't worry, it's nine o'clock in the evening, exactly twelve hours away from you"!

When her mother heard Xu Le's words, she cried, "You should pay attention outside", and then hung up, Xu Le also felt uncomfortable, but she still sent a message to Qingning and her godmother, "It's here!" ”

The godmother replied with two words, "Okay"!

Qing Ning replied, "We are still in Chang'an, my classmates in New York will contact you, remember what I told you!"

Xu Le looked at his luggage while thinking about Qing Ning's words, "You have told me a lot, which sentence do I remember?"

Xiaobai's big cage came out first, Xu Le directly brought the cage over, these people next to him looked at Xu Le, looked at Xiaobai, Xu Le looked at the number, and released Xiaobai, the two looked at the people next to them, "There are so many foreigners"!

'Yes, you're in the alien's den'!

Xu Le knew that Xiaobai was suffocated along the way, he was either discussing problems with them or endorsing him, and he didn't have time to take care of him, but this food was good, because when he was in Anchorage, someone complained that he brought less food, and he knew that Xiaobai did it!

Everyone waited for almost an hour to finish picking up their luggage, and then under the leadership of Mr. Hou, they went outside, and the old smokers smoked wildly, making Xu Le laugh!

"Okay, everyone get in the car with me, the time difference here today is exactly Friday, we will live in New York City tonight and tomorrow night, and we will leave for Hefu University after lunch at noon the day after tomorrow", Mr. Hou said to everyone!

Xu Le and others' travel expenses this time are not particularly much, mainly based on academic discussions, a total of four business rooms, Xu Le has one, no matter how young he is, where the position is, but there are three ladies, it is very troublesome, either to transfer the room or to spend their own money, Hou is always a little embarrassed, and finally Xu Le gave his room to Wu Xiaohong, this is Beijing University, he told everyone that he has friends here, and he may go to his friends to have a look!

Xu Le doesn't have any friends here, he just doesn't want to make it difficult for Mr. Hou and everyone!

It was already ten o'clock in the evening when I arrived at the hotel, and everyone was not sleepy, and finally they all came to Professor Zong's room to listen to him talk about astronomy, a room full of people, and the staff of the local foreign affairs department had been waiting for the staff to buy a lot of gnawing chicken, as well as Coke, Xu Le paid for a lot more, and Xiaobai's, Xiaobai also listened to the lecture with everyone!

Suddenly, everyone heard Xu Le's mobile phone ringing, Xu Le didn't know the number, a long list of numbers, he connected the phone, it was actually English, a very enthusiastic voice, "Is it Xu Le, I'm Huo's good friend Serena"!

Xu Le hurriedly said, "Hello"!

"Do you have time at night, let's go out and have fun together, see the beautiful night view of the society of the lord of capital, and experience the depraved way of life", then the woman giggled, Xu Le was a little puzzled, am I so familiar with you?

However, he still said that it was too late at night and he was a little tired and needed to rest!

The girl didn't say much, she still had a little trick and said in frustration, "Okay, where is your address, I'll look for you tomorrow morning"!

Xu Le then said the address and hung it up, everyone looked at Xu Le, he really has friends here!

Xu Le apologized to everyone, and then, Professor Zong first popularized the basic history and mathematical knowledge of astronomy to everyone, Xu Le compared the knowledge content he had just read and what he thought about and the Tibetan calendar and astronomy in the Tibetan soil area, constantly nodded and shook his head, and after a while, a few teachers left, this is really not a system, and mathematical knowledge is also needed, not something that can be understood temporarily, but it is all some idle to listen to, and there is not much to learn!

Xu Le, Wu Xiaohong, and Nie Yinhong are really studying, and when they get to the back, they start to talk about the real thing, most of the people are gone, even Xiong Jiange is gone, and finally there are only three of them left, Professor Zong began to talk to Xu Le seriously, starting from the "Book of Heavenly Officials"!

In order to understand the stars and study the celestial bodies, the ancient Chinese people artificially divided the starry sky into several regions very early, called them star officials, and called them constellations in the West. In ancient China, the sky was divided into three walls and 28 houses, and the whole day was divided into "five palaces": the "middle palace" refers to the heavenly area around the North Pole, symbolizing the central court represented by the Emperor of Heaven; The eastern, southern, western, and northern four palaces are established with the star official of the biquintox and the solstice as the center, corresponding to the four seasons, symbolizing the four seasons palace where the emperor of heaven patrols the world.

The meaning and location of the Zhonggong Tianji Star, the three stars of the front straight bucket, the seven stars of the Big Dipper, the six stars of Doukui Dai Kuang, and the two stars of the Dipper, followed by the five star palaces of the East Palace, the South Palace Vermilion Bird, the West Palace Xianchi, and the North Palace Xuanwu;

Next is the age of Setig, the age of Shan Yan, the age of Zhixu, the age of Dahuang Luo, the age of Dunqi, the age of Ye Qia, the age of Shutan, the age of Zuo E, the age of Dayuan, the age of Sleepy Dun, and the age of Chifenruo, the twelve stars of the year, which correspond to Yin-Setig; 卯—single 阏; Chen—Zhixu; 巳 - the great wilderness, the great wilderness; Afternoon - Dun Mu; Un- Ye Qia, Xieqia; Shen-Shotan; 酉 - to be a house, to be a nightmare; 戌 - castration, cover mao; Hai - Obuchi offering.

Professor Zong looked at the three of them studying seriously, especially Xu Le felt as if he had learned, and asked him if he had learned, Xu Le said that he had learned the Tibetan calendar astronomy when he was in the Tibetan soil area, Professor Zong was happy, and kept discussing with Xu Le, Xu Le also compared the content of the Tibetan calendar astronomy to everyone, even Professor Zong benefited a lot, and when everyone suddenly talked about the year, Xu Le said:

"Professor Zong, because I understand the Tibetan language, I think this set of things is wrong in Huaxia's understanding"! Xu Le said very seriously, "Do you know how to pronounce tiger in Tibetan language?"

After Xu Le finished speaking, Nie Yinhong's eyes lit up, "Seti", Xu Le said the pronunciation of the Tibetan language, "There are several more that are right, I don't know what everyone says, I think this is the pronunciation of the ancient Tibetan and Chinese pronunciation"!

"That's right, I also felt like it was Tibetan when I read Stige just now", Nie Yinhong also said, and Professor Zong was stunned for a moment, but he was still very happy, "Really? Because I don't know Tibetan, I don't know how to pronounce it!

Xu Le and Nie Yinhong both nodded, and Professor Zong stood up and laughed, "People, you really have to study more, Xu Le, Yinhong, you two can have a good exchange on this problem, if you can really solve this, it will be very interesting!"

Xu Le looked at Yin Hong, "You can write it, I won't study this anymore, I don't have time, you have any suggestions or ideas to talk to me"!

Nie Yinhong suddenly became happy, "Thank you, thank you", Nie Yinhong knew that Xu Le had left the opportunity to himself, and Wu Xiaohong was very envious of them, but she didn't study languages after all, she studied astronomical science, so there was no way.

"The word setig is very inconsistent with the way the Han people use words, how to form these three words, is it single or two two, it's not right, the take-up has just risen, the meaning of mentioning is taking, these two are suspected of repeating, is the style of the grid, as if it is not, Gewu"?

Xu Le said Gewu, and was suddenly stunned, who would do it all over that planet?

He suddenly thought of the banner of Chiyou and the qi of the Yellow Emperor, is there really an ancient god who takes the planet? Xu Le shuddered, does this also show that Zhongkang is really hiding behind the solar eclipse?

Xu Le still listened to Professor Zong's lecture first, and then talked about the Emperor Star, Zhao Xing, the Five Remnant Stars, the Great Thief Star, the Siwei Star, the Prison Han Star, the Four Filling Stars, the Candle Star, the Heavenly Drum, the Heavenly Gu, the Chiyou Banner and so on;

Later, before the inheritance of astronomical numbers from the Yellow Emperor to Gaoxin, there were heavy and li; Yu Tang, Yu, Xi, He; There are Xia, Kunwu; Yin Shang, Wu Xian; Zhou Room, Shi Yi, Chang Hong; Yu Song, Ziwei; Zheng Zepi; In Qi, Gan Gong; Chu, Tang Ying; Zhao, Yin Gao; Wei, Shi Shen and so on.

In the end, I said that every life in China basically changes at the age of 30, changes in a hundred years, and changes in 500 years; Three major changes and one era, three eras and great preparation.

Xu Le listened to the explanation, thinking about his grandmother, grandma actually arrived three thousand years ago, or woke up, and then waited for three thousand years, and in the fourth thousand years, she couldn't wait anymore so she left, and finally left her essence, Xu Le knew that this was not necessarily for herself, it was just a coincidence of her own karma, she might actually be waiting for that Zhao Xian, right?

Maybe even earlier, Xu Le was looking at some famous figures in history, and there were some special people in miscellaneous books, but then he gave up for some reason!

"Professor Zong, do you believe in the ancient gods?" Xu Le asked faintly, that tone seemed to have traveled through thousands of years, and everyone listened to it, Wu Xiaohong just thought it was funny, but Professor Zong and Nie Yinhong were obviously different!

"Xiaohong, it's all over, I want to talk to Professor Zong about something, you can rest early!"

Xu Le said to Wu Xiaohong, Wu Xiaohong's don't look at her thirties, then you have to call Xu Le uncle, so Xu Le has nothing wrong with calling her Xiaohong!

Although Wu Xiaohong was a little aggrieved and wanted to listen to it, she knew that since Xu Le didn't want to let herself listen to it, it might not be suitable, so she thanked Professor Zong and went out!

Xu Le looked at Professor Zong and Nie Yinhong and said, "Professor Zong, you are studying astronomy, in fact, you should be able to find more things that do not conform to common sense, the history of China does have forgeries, I don't deny it, but you know that some are intentional and some are unintentional, but there must be something hidden during this period!" Have you ever thought about a question, Gewu Zhizhi, the so-called setig, just like I just said that the Tibetan language is Seti, not Setige, but Gesetti"?

The two of them stood up at once, and felt a great shock, who can take a planet as a reference?

"Professor Zong, I would like to ask you, is our dating project based on astronomy, carbon 14, and writing, and then based on archaeological objects?" Xu Le did not participate in any in-depth discussions, he believes that there are some core experts who must be constantly discussing the way of argumentation and archaeology with Li Guowu and the Song Dynasty, among which there must be a main line, and as an astronomy, it cannot reach the level of deputy team leader at all, but Professor Zong, as the deputy team leader, must be based on these three main lines, through the interpretation of the text, determine the upper limit of the text, and then comb the place names of ancient books for accurate exploration and excavation, and then judge the dynasty against the events of carbon 14 and astronomyThis should be the main workflow of this generational project!

Professor Zong looked at Xu Le, he was really a demon!
