The historical records of the Chinese people, their accuracy and authenticity, are the best in the world!

Naturally, there is no need to question this.

When he saw the copper leaky pot, Chen Han couldn't help but once again be rigorous about the "history" of the ancients.

More than 2,000 years ago, a time signaling device was accurately recorded in history, so that future generations more than 2,000 years later can get a glimpse of the life of the Chinese people at that time.

"Time" doesn't seem like a very important thing.

Especially for modern people, there are time displays on mobile phones, computers, clocks and other carriers.

It seems that knowing what time it is not a difficult thing to do.

However, in fact, whether or not we can know "time" is the most important thing whether a civilization is advanced or not.

It can feel disconnected to say it.

Don't look at modern society, it seems that scientists can already accurately measure the time scale to one ten-thousandth of a second.

However, there are still many places on earth where even time cannot be grasped.

Whether it's some indigenous tribes in Africa or some indigenous people in the Mesoamerican rainforest.

They are still in the era of slash-and-burn farming, and at most they can only roughly grasp whether it is morning, afternoon, noon, or night.

As for the specific points, we can only rely on the position of the sun to make an estimate of the model lake.

This is also the reason why these natives can only be limited to the primitive Stone Age, and they have not been able to develop advanced civilizations for thousands of years.

Because they didn't invent a timekeeping device, they couldn't know the time, they couldn't develop a regular calendar.

Without a calendar, there would be no stable farming society or animal husbandry society, and we would only be able to live on the weather and hunting.

If the society is unstable, then there will be no way to become rich and develop the system, economy, and culture of the society......

The modern countries that now live on the earth can be traced back to B.C., and they all developed to their current state by mastering time and calendars.

Westerners originated from the ancient Greeks who divided day and night into 12 hours and divided the four seasons into four seasons 3,000 years ago.

Later, this method of timekeeping and the original calendar spread to Europe and remained in use until the 14th century.

And Huaxia, it was even earlier.

At present, some Neolithic sites have been discovered, and there are ruins of "watching the sky", and very primitive sundial equipment has been discovered.

The principle is actually "immediate", relying on the shadow of the sun to determine the time at this time.

Legend has it that after the Yellow Emperor defeated Chiyou and unified the world, he ordered people to formulate a calendar, which is known as the Yellow Emperor Calendar.

In the following Xia Dynasty, there was the first calendar that professionally guided agriculture, that is, the earliest Xia calendar.

After the summer calendar, there are also "Yin Calendar", "Zhou Calendar", "Lu Calendar", and "Zhuan Calendar", which are collectively known as the ancient six calendars!

Among them, the earliest, and there is a specific calendar content record, is the "Zhuan Calendar", which is the calendar used by Qin Shi Huang after the unification of the Six Kingdoms.

However, the "颛顼 calendar" was not formulated during the Qin Shi Huang period, according to legend, it was formulated on the weekend, but later after Qin Shi Huang unified the six countries, he unified the six kingdoms calendar, stipulating that the whole country should use the "颛顼 calendar"!

But when the "Zhuan Calendar" was formulated, the Yellow River was still running elephants!

By the time of Emperor Wu of the Han Dynasty, Emperor Wu of the Han Dynasty deeply felt that the "Zhuan Calendar" was no longer in line with the times, and the calendar was no longer accurate.

So the calendar was revised again.

This is the familiar "Taichu Calendar" with January as the first month of the month!

The well-known rain, vernal equinox, valley rain, small man, summer solstice, great heat, summer heat, autumn equinox, frost, light snow, winter solstice, and great cold are all from the "Taichu Calendar"!

At that time, the "Primal Calendar" set the year of return as 365.25 days, and one synodic month was equal to 29.53 days!

And for the first time, the cycle of the five stars was recorded, and the conjunction period of the planets was measured accurately!

For example, Mercury is 115.87 days, which is only 0.01 days smaller than today's measurement!

Using a 135-month eclipse cycle, the sun passes through the yellow and white nodes 23 times in one cycle, and two eclipse years are one eclipse year, that is, one eclipse year = 346.66 days, which is less than 0.04 days larger than today's measurement!

It's hard to imagine that this is a BC calendar!

The astronomical calculations made by the Chinese people in BC are only between 0.01 and 0.04 days less than the calculations made by scientists today with advanced observation instruments!

And this advanced calendar was officially launched in 104 BC, 58 years earlier than the ancient Roman "Julian calendar" with similar accuracy!

In the field of astronomical exploration, ancient China has come to the forefront of the world!

Thanks to the good habits of the Chinese people in writing history, from the Zhou Dynasty 3,000 years ago to the Qing Dynasty, all the comet return data have been recorded in the history books!

So much so that astronomers around the world, when studying comets, need to look for records of comet returns from the historical records of China!

There are also ancient star maps, and only Huaxia's record is the most accurate and correct in the world!

Don't look at some foreign and Western historians, they have all kinds of doubts about the Three Emperors and Five Emperors recorded in the "Historical Records", as well as the history of Xia and Shang, and feel that there are too many fantasy colors, which are not enough to believe in history.

But Western astronomers, the body is very honest.

When they wanted to find astronomical records of BC, they all used the records in the "Historical Records" as the only research material.

There is no way, except for those astronomical records in the "Historical Records", such as the celestial phenomena, comets and meteors, clouds and strange stars, more than 90 groups of star names, more than 500 star records, the movement laws of the five planets, and the periodicity of solar and lunar eclipses.

"The Sword Comes"

There are also historical astronomical events recorded in the Records of the Historians.

For example, in August of the second year of Emperor Jing of the Han Dynasty, the comet came out of the northeast.

In the autumn of the second year, Yingfu went retrograde and guarded Beichen. Between the moonrise and the north star. The year star retrograde in the heavenly court.

This is a special astronomical record of the retrograde motion of Mars and Jupiter in the second year before Emperor Jingdi!

Several times around the world, the retrograde motion of Mars and Jupiter in 155 BC was observed and recorded only by the Chinese!

This is a miracle in the global astronomical community!

Now, more than 2,000 years later, earth astronomers can still have astronomical records from more than 2,000 years ago available for reference and research!

For this alone, Huaxia's contribution to the world astronomy community is already huge!

From an astronomical point of view, thousands of years of time are just a snap of a finger for astronomy.

The study of astronomy and the recording of data often have to be based on thousands or even 10,000 years as the time unit, so it can be said that the study of astronomy is a work that needs to be recorded for a long time.

The historical record of China has undoubtedly contributed an astronomical record of two or three thousand years to modern astronomy!

This is the most brilliant legacy left by the Chinese ancestors to the world!
