Great Tang princess

Chapter 721 The Importance of the Calendar

In Jixian Temple, Princess Yiyang asked Li Yuechen what should be written in the newspaper about blood type.

She explained from the side, and Wu Zetian and others listened carefully.

Every time I listen to her talk about these special things, I feel very knowledgeable.

"Most blood types are divided into four categories." Li Yuechen introduced, "So they can be divided into Type A, Type B, Type A and B, and... Type G."

Originally, she wanted to name it Type C, but after thinking about it carefully, considering the special nature of Type O blood, she decided to name it Type G.

After all, some other special blood types will be discovered in the future, and they can be named in other ways at that time.

Princess Yiyang recorded the main points she said one by one, and then she was going to go back and polish it up.

Just as she was about to leave, Wu Zetian raised her hand to stop her: "Wait a minute, it happens that Chen'er is also here, and we just happen to have a look at the treasures that Nanzhao Kingdom paid tribute to."

Li Yuechen raised his eyebrows, it stands to reason that this kind of treasure that other countries pay tribute to is nothing to see.

Especially on the side of Nanzhao Kingdom, basically all kinds of jade were sent over.

"Aniang, I don't know much about jade, or..."

"It's not jade, but a big stone slab!"

Li Xian who was next to him said, "I went to see it for my brother yesterday. There was a huge skeleton on the stone slab. It was so lifelike, it was very beautiful!"

Li Yuechen curled his lips: "I don't even understand sculpture."

Just as he was talking, Zhang Chengxin brought in twenty or so little eunuchs carrying a dusty slate.

The length and width of this stone slab are more than one zhang, and it is thanks to the large enough Jixian Hall, otherwise it might not be able to fit it.

Twenty or so young eunuchs struggled to carry this thing, and they were moving it in little by little.

As they gradually put it down, Li Yuechen took a closer look. There was a skeleton on the big stone slab. It looked like a fish, but it was not the same.

The skeleton is not complete. It seems that there is only a head and a chest. It is not clear what the body looks like.

But with a spine and fangs over twenty centimeters in length, it should be some kind of large predator.

Li Xian came over at this time: "The Nanzhao envoy who paid the tribute said that this is not a man-made carving, but a blessing from God, so he sent it... But Brother Wei felt that they were cheating on Auntie, because they didn't want to pay tribute jade, so they sent it to us. Use this kind of carving to make up for it..."

Wu Zetian on the side didn't speak, but he still agreed with Li Xian's statement.

However, Li Yuechen stretched out his hand to touch the stone slab, shook his head lightly and said, "I'm not sure, I can ask the craftsman from the Engineering Academy to come and have a look. But this thing may not be carved by humans."

"Oh?"

Hearing her words, Li showed a look of curiosity: "It's not a sculpture, is it a natural formation?"

Li Yuechen nodded slightly: "This is probably a fossil."

"Fossil?" Li Xian didn't quite understand.

"Whether it is a person or a livestock, after death, they are buried in the ground. After the flesh and blood disappear, the bones will gradually fuse with the surrounding stones to form fossils." Li Yuechen said, "If the tombs of the Yin and Shang Dynasties are opened at this time, the sacrifices inside And so are my slaves."

Shangguan Wan'er suddenly became interested: "But Your Highness, looking at the skeleton, the head is so huge, isn't this beast several feet in size?"

"Is there really such a beast in this world?" Wu Zetian held up the teacup, "If you can catch it..."

"Don't think about it, Mommy, it doesn't exist now." Li Yuechen smiled and shook his head, "This is probably a dinosaur fossil."

"Dinosaur?" Princess Yiyang was bewildered.

I have heard of Lilong, Candlelong, Jiaolong and various dragons, but I have never heard of dinosaurs.

Li Yuechen smiled: "On this earth, there are all kinds of creatures. We can be called humans, others can be called beasts, most of the sea can be called fish, and most of the sky can be called birds." ...and before the birth of human beings, this earth has passed through countless epochs, and during some of these periods, this dinosaur was the ruler of the earth at that time..."

Listening to her recounting the events of the ancient times, Li Xian subconsciously felt that it should be made up.

But after asking a few questions, he found that he could still justify himself, which made him feel suspicious.

Li Yuechen briefly talked about what he knew about dinosaurs, and then made a summary: "In short, human beings appeared long after the extinction of dinosaurs. But it is not completely extinct. In fact, today's Chickens, ducks, and most birds are descended from dinosaurs..."

Listening to her science popularization, everyone didn't know what questions to ask in the end, because the impact on the ancient people was too great.

"In short, probably after the Cretaceous period, dinosaurs became extinct. It is more reliable to say that meteorites washed the land at that time, but I don't know whether it is true or not..." Li Yuechen made a final conclusion.

Li Xian said with a confused face: "Meteorite...you mean meteoric iron?"

"Yes, it's a meteor!" Li Yuechen nodded, "Most of them can't fall to the ground, but if they are too large, they will cause a terrible disaster..."

Wu Zetian also raised her own question: "Chen'er means that after all the dinosaurs died, Nuwa started creating humans?"

"Hmm..." Li Yuechen frowned and thought for a while, "Actually, people... might be transformed from monkeys."

"What?" Li Xian's eyes widened all of a sudden, "We are the spirit of all things, how could it be changed by a monkey?"

Such a statement really made him feel that the three views had been greatly impacted.

Li Yuechen decided to tell him this for future consideration.

After all, with the improvement of civilization, technology must also develop.And this country is not a religious country, so it is better to know this information in advance.

"Just like dinosaurs have become today's chickens and ducks, life has to learn to adapt to the environment. If you can't adapt, you can only die." Li Yuechen picked up the teacup, "When the monkey feels that it is not suitable to stay on the tree , When deciding to survive on the ground, it may take tens of thousands of years to change the posture to walking upright. In this way, the hands are freed, and more tools can be used and made. So I began to think about more complex tools and weapons... ..."

Although she doesn't specialize in this, fortunately, she can explain it clearly with her own knowledge.

But the impact of these words on everyone was extremely huge, and they froze in place for a moment, not knowing what to say.

After a long time, it was Wu Zetian who was the first to take a deep breath: "Chen'er can't say these words."

"exactly……"

Even Li Xian, who was always lazy on weekdays, had a serious expression on his face: "This matter may be related to the stability of the royal family..."

"It's not that exaggerated!" Li Yuechen waved his hand, "Our family is not next door, so there is no need to maintain the rule through mythology. Or the same sentence, as long as the common people are fed and clothed, no one is willing to carry their heads to rebel .”

In fact, most people in this world are muddling along. There are many ambitious people, but very few are really willing to pay for it.

"Don't talk about the common people, just talk about these aristocratic families..."

"Brother, don't worry, these aristocratic families can't make any troubles at all. If I was a few years ago, I might still be afraid, but now...hehe!"

She didn't continue to say the following words, but the meaning was self-evident.

Now that the four major military regions have completely reformed, let alone a certain family wants to rebel at this time, even if all the families unite to make trouble, Li Yuechen can solve it smoothly.

And after solving it, he can do all the aftermath work well, that's how confident he is.

"Brother, you have to understand that there are only two types of people that really matter in the future!" Having said that, Li Yuechen raised two fingers, "That is workers and farmers!"

"what for?"

Li Yuechen smiled: "These two types of people are the cornerstone of a strong country!"

"Okay, okay, it would be strange if he understands your theory!"

Wu Zetian waved his hand suddenly: "Anyway, today's conversation must not be spread..."

As the emperor, she still has a lot of considerations. It is better not to let outsiders know about such remarks that may cause a national earthquake.

It can be regarded as a joke between family members in Jixian Temple, but if it is said out, it is not a joke.

After all, she is a majestic princess, and every word she says outside will be over-interpreted, and it will be bad if it causes trouble.

Li Yuechen didn't argue with his mother positively, and agreed very obediently.

……

The next day, Li Yuechen didn't go to the palace, but went directly to the Academy of Engineering, and discussed with them about the astronomical telescope.

Besides, I didn't come alone today, and I brought all the children of the royal family from the military academy, which can be regarded as an outdoor class.

In the Engineering Academy, Pei Bishu came out to greet and salute, and then led everyone inside.

"Your Highness, all nobles, please follow me."

While leading the way, he chatted with Li Yuechen about recent events.

"Speaking of which, how is the progress of the typewriter?" Li Yuechen asked.

Pei Bishu shook his head: "Returning to Your Highness, many of the parts are too precise and have not been completed yet, but they are faster than expected. If there are no accidents, the initial results will be seen early next year."

"It's okay, this kind of thing can't be done overnight, and I can understand it." Li Yuechen smiled and gave encouragement.

When they came to the laboratory, Li Yuechen recruited craftsmen, let a group of children from the royal family sit with them, and began to chat about the astronomical telescope.

Facing such a group of noble children of the royal family, the craftsmen were more or less uncomfortable.

But after Li Yuechen started to talk, the atmosphere slowly became normal.

The main reason is that Li Yuechen is too familiar with them, so he is not too afraid of these children.

"The astronomical telescope, as the name suggests, is a telescope specially used to observe celestial phenomena. Compared with the ones used by the army, it is somewhat different... This object is mainly used by the Qin Tianjian..."

Not only the children of the royal family came here today, but also a group of senior leaders from Qin Tianjian.

The main reason is that this thing is mainly used by them, so it is necessary to refer to their opinions in many places.

Li Yuechen supported them to build astronomical telescopes, not for astronomical research.

It's another thing that everyone knows, but will gradually become less important in the future-calendar!
In the future, in order to be in line with international standards, the Western Gregorian calendar will be adopted instead of the traditional lunar calendar.

In fact, Li Yuechen didn't know until he came to this era that the calendar at this time is not called the lunar calendar.

The lunar calendar refers to the 24 solar terms, the lunar calendar is the lunar calendar, and the Gregorian calendar is the solar calendar. The combination of the three forms the "lunar calendar" that will be known to people in the future.

In this era, the name of the calendar is "Huang Li".

Since ancient times, only the rulers can modify and promulgate the calendar, so it is called the "imperial calendar".

However, in the future, due to various reasons, the actual conflict between the Gregorian calendar and the lunar calendar will still be quite large.

Although some urban residents and most rural residents still celebrate their birthdays according to the lunar calendar, they don't deliberately remember them on weekdays.

Basically, I only go on business when my birthday is about to be celebrated, otherwise I don’t even know the Gregorian calendar date corresponding to my birthday.

In an environment where dual calendars run side by side, there will eventually be one side that will gradually become neglected.

Take the word "New Year's Day" as an example. Originally, this word refers to the meaning of New Year, but in the future, New Year was changed to "Spring Festival".

It seems that what everyone celebrates is not the New Year, but the Spring Festival.

In fact, in today's calendar, these are two completely different concepts.

Because the Gregorian calendar and the imperial calendar have different dating methods, for example, now, according to the Gregorian calendar, it may be a certain year between 695 and 700 AD, and Li Yuechen is not sure about the specifics.

But in the imperial calendar, this year is the Year of the Rooster.

Of course, in the future, many people will no longer be familiar with the method of counting the years of the heavenly stems and earthly branches.What's more, in fact, many people have gradually begun to focus on the Gregorian New Year.

For example, many temples and Taoist temples will hold blessing activities on this day. Before the outbreak of the epidemic, there were crowds of people in many cities' New Year's Eve activities...

Li Yuechen didn't really hope that this matter would continue to happen in this time and space.

No matter what kind of calendar, as long as it can be passed down, there must be a huge cultural power behind it!
Taking the 24 solar terms as an example, it is no exaggeration to say that it is the fifth greatest invention!

Li Yuechen hopes that the calendar of the future world will be dominated by the oriental calendar, which will make the influence of oriental culture spread more far-reaching.

And the year 2021 before this era was not because of any great events that happened on the earth before 2021, but because Westerners believed that Jesus was born in that year, so they set that year as the first year of AD .

The calendar is indeed just a timing tool, but it is also related to cultural self-confidence and identity. Li Yuechen hopes that young people in the future can understand this.

Just like Li Yuechen likes Chinese characters, not because Chinese characters are her mother tongue, nor because of its use value.

But in that stroke, one can touch the special sense of existence that belongs to this civilization, and the cultural context spanning thousands of years.

"This palace hopes that you can study it with all your heart. After thousands of years, it will bring great value to our descendants!" Li Yuechen said slowly to all the craftsmen present.
