Whether ancient China knew Haipao, the evaluation of ancient Chinese education, urgent! Thank you!

Ancient China did not know altitude.

Altitude in the sense of geography refers to the vertical distance above or below the sea level of a certain place or geographical thing on the ground, which is the abbreviation of altitude. It is the opposite of relative altitude, and the reference point for calculating altitude is to confirm a commonly accepted sea level. This sea level is equivalent to a 0 scale in the ruler.

For this reason, altitude is also referred to as absolute altitude or absolute elevation. Relative altitude is the difference in altitude between two points when compared to each other. But the tide of the sea rises and falls, the big waves and small waves do not stop, it can be said that there is no moment when the wind is calm, and every month.

Geoid.

There is also a clear difference in the sea level between the daily high and low tides. Therefore, it was thought that only a definite average sea level could be used as the starting surface for elevation. Elevation is defined as the height above or below the average sea level.

This is what is commonly referred to as elevation or absolute elevation. Due to the heterogeneity of the Earth's internal mass, the gravitational lines at various points on the Earth's surface do not all point towards the center of the sphere. In this way, the geoid is perpendicular to the direction of the gravitational line, forming an irregular surface.

As a result, countries around the world have their own established mean sea level, known as the geoid level.

Surveying and mapping experts have adopted the method of setting up tide gauge stations along the coast. Select a port area with the characteristics of moderate location, open sea surface, flat seabed, stable geological structure, representative and regular semi-diurnal tide for a country or region, establish a long-term tide gauge station, and determine an average sea surface according to the long-term tide gauge data, and take it as a zero elevation surface.

Then, the precision leveling joint measurement is used to measure the pre-set level origin on land, and the altitude of this point is determined as the starting elevation of a country or an entire region.

Obviously, there were no conditions in ancient China.

I definitely know, but it is different from the unit of measurement used now, and the ancients used a ruler or something.

Not. The concept of altitude was introduced by modern Western surveying and mapping.

A brief summary of my evaluation of the ancient method of education: I personally think it is good to use violent means to make students learn and remember the mistakes they have made. Nowadays, exam-oriented education is suitable for this, and everyone can become a college student if they are educated in this way.

The ancients generally studied four books! University, the mean, Mencius, Spring and Autumn, six arts!

Etiquette: Etiquette (i.e., moral education today).

Happy:**. Archery: Archery skills (forging chain physique, character cultivation).

Mi: The technique of driving a horse-drawn carriage.

Book: Calligraphy (modern literature).

Number: Algorithm (i.e. mathematics).

Before liberation. Our country is in a period of constant conquest by princes on all sides. Education in ancient times was largely focused on men. Half a century later than the ideas of other countries in the West.

Moreover, there is a serious division of educational classes. Almost all of the people who go to school are the children of wealthy families.

Feudal, decadent, stifling the human spirit (there are many, many more just don't know how to express it).

In the north, he fought Outer Mongolia and Russia; Vietnam, Myanmar, Laos, and the Philippines in the south are the whole of Southeast Asia; In the west, he fought Pakistan (known as the East Indies in ancient times), India, and Nepal; Not to mention Korea and South Korea in the east, which were itself vassal states, including the Ryukyus and Japan, which also fought during the Yuan Dynasty, but did not succeed.

Khan, let's put it this way, basically the neighbors you see on the historical map have fought. It seems that Nepal and a few other remote and small countries have not been hit.

Every dynasty and every generation have been fought, and there are really hundreds, and there are also detailed dynasties.

Merchants in ancient China had a very low status.

For example, a businessman, you are rich, but you are not allowed to wear beautiful clothes.

Moreover, if you are too rich, you will be exterminated by your family, such as Shen Wansan.

History is the trace of a wavy line, with ups and downs.

From different angles, it seems to have the same result. In terms of values and outlook on life, human beings have gradually become evil from good. From the history of science, there have been many inventions in ancient times, and the so-called brick family has not been able to explain the mystery, which can be said to be unprecedented.

In terms of the spiritual realm, the ancients were good at singing and dancing, but modern people are all popular.

However, although in our view, the ancient prosperous era was a peaceful and harmonious society, with the transformation of human nature, history will eventually change, and history at any stage is just a product of the cognition of human nature at that time. When looking at history, we can't look at it from the perspective of the past or the present, but from the perspective of the time, the so-called everything is in motion, but it is relatively static.

To sum up, the prosperity of ancient times is just some shining points in the trend of history, and it cannot make the prosperity immortal forever, and in the long history, it is just a flash in the pan.

Just like the current society, in the eyes of many people, it is a peaceful and prosperous era, but behind corruption, greed, oppression of poverty with the rich, and oppression of the people by officials, it will eventually be replaced, and what will replace it, can only let history prove, no one can predict, even Marx, is not necessarily right.

In ancient times, only the Spring and Autumn Period and the Warring States Period were prosperous, and the most democratic and free era at that time was not other periods in ancient times.

During the Tang Dynasty, China was the economic and cultural center of the world.

Not only is the economy developed, but also the spirit is supreme, and now it has only reached the first point, and it is still far from the second point!

In the prosperous era of ancient Chinese society, there were very few such as the prosperous Tang Dynasty, and the prosperous era of Kangqian was just a period when there was less cholera, and it was much worse than the prosperous era!

Promote the development of social productive forces.

What inventions??? You tell you to be specific, there are more inventions from our ancestors.

This is not true, and according to current scientific terms, the soul does not exist. This statement is quite superstitious in the same way as ghosts and gods. Generally Buddhism only believes.

Persia and China did not fight in ancient times, and the Persian Empire's sphere of influence was mainly in the Mediterranean, while China was still in the Spring and Autumn Period and the Warring States Period, and its sphere of influence was in East Asia.

Due to its location in the middle of the vast area connecting China, the Roman Empire and North Africa, the Persian Empire was China's largest partner and the most important exchange country during the Han and Tang dynasties.

From 87 to 101 A.D., Persia sent two envoys to China. During the Northern and Southern Dynasties, Sassanid Persian envoys made more than ten missions to China. Due to changes in the political situation, the political ties between China and Poland have been interrupted from time to time, but cultural exchanges are endless.

China had technology that Greece and Rome could not match, so Persia cherished its dealings with China. At this time, Persia shifted the focus of its foreign exchanges to the East, becoming the first hub of communication between the East and the West, and once monopolized silk.

In recent years, thousands of Sassanid Persian silver coins have been unearthed in China, which shows that Persian merchants were active in their exchanges with China at that time. The prosperity of the Silk Road also stimulated cultural exchanges between China and Persia.

The first unification of Persia was in the Achaemenid Empire, the most powerful version of the famous Darius I, BC.

Around 500 years old, it was defeated after three Greco-Persian wars, and finally Greece and Persia were destroyed in Macedonia.

At that time, the Zhou in China had declined and entered the Spring and Autumn Period and the Warring States Period.

The Sassanid Empire (226–650) was the reigning Persian dynasty between the 3rd and 7th centuries CE, the first unification of Persia since the Achaemenid Empire, and is considered the second Persian Empire. At that time, the Sassanid Dynasty was known as the Kushan Dynasty in Central Asia, the Eastern Han Dynasty in East Asia, and the Roman Empire in Europe. At its peak, the Sassanid Empire repeatedly threatened the neighboring Kushan Empire and the Eastern Roman Empire.

And the engagement with China is good.

Later, due to the years of war between Persia and the Eastern Romans, it was attritional, but the Arabs arose, and Persia was destroyed by the Arabs. Balus, the son of the last king, Yi Si Yi III, fled to the Tang Dynasty and served as the general of the Right Wuwei, when the Tang Dynasty was ruled by Tang Gaozong.

However, the Arabia that replaced Persia has been fighting with the Tang Dynasty for the dominance of Central Asia, and the Tang Dynasty had the advantage in the early stage, and the battle of Heng Rus, although the Tang Dynasty suffered a slight setback, but if it was not for the Anshi Rebellion, the victory or defeat was not known.

Persia, though strong, accounted for less than four-fifths.

Didn't fight. During the era of the ancient Persian Kingdom, China was in the Spring and Autumn Period and the Warring States Period. At that time, China was dominated by the Xiongnu in the north, Yueshi and Wusun in the west, the Sai people in the west, and the Bactria in the southwest.
