The previous dynasty had a territorial limit, but Dahua actually has no such shackles.

At the beginning of the eighteenth year of Yongxing, the submarine cable project from Ireland in Europe to Quebec in North America was completed, connecting the communications network in the Americas with the Eurasian continent.

This means that Dahua's telegrams and telephones have touched all land except Antarctica, realizing global instant communication.

Any place in the world is a little different, and the central government in Nanjing can quickly know unless the communication station is controlled.

However, if the communication station is controlled, the center can also detect its abnormality.

In short, today is different from the past, and the difficulty of rebellion has greatly increased.

This is just one of the many benefits of instant messaging. The biggest advantage is that it facilitates the control and management of various places, and holds the decision-making power of major events in your hands, without the need to delegate power.

At the same time, the central government has greatly strengthened the supervision of local governments, and it is difficult for the emperor to be far away.

The magistrate of breaking the family, the prefect of destroying the door.

In the past, the local officials were really like the emperors of the earth.

Even if they have done all kinds of illegal things, not many people have the ability to report to the capital.

Even if you report it, one time and one time, it is enough for the local officials to destroy the evidence.

Nowadays, the monitoring agencies distributed in various places can report to the central government in the shortest time.

However, the Americas Telecom Network is only connected to those important cities, most of the places are not yet connected to electricity, and the construction is still in full swing.

In the Central Plains, the telecommunications network has almost covered the eastern and central regions.

The cities are divided according to the first to fifth lines, then the cities above the fourth line have already been on the phone, and any county has a telegram.

The criteria for the classification of metropolitan cities are comprehensively measured from the two aspects of scale and economic development.

Roughly speaking, cities with a population of more than 5 million are the first-tier cities, including Nanjing, Shanghai, Guangzhou, Wuhan, Tianjin, and Edo.

Those with between 2 million and 5 million are second-tier cities, and this is more. Many of these are the capitals of major economic provinces and historical cities overseas, such as Nanchang, Hangzhou, Hanoi, Delhi, Suzhou...

Between 1 million and 2 million are third-tier cities, and this is even more.

Provincial capitals with less developed economies, prefecture-level cities in economically developed areas, some historical cities overseas, and population clusters. Such as Xuzhou, Zhenjiang, Wuhu, Nagoya, Kagoshima, Seoul...

The population between 300,000 and 1 million is the fourth-tier cities, the capitals of some underdeveloped regions, the ordinary counties and cities in the Central Plains, and the densely populated areas.

Such as Tubo, Hami, Zhumadian, Shaoguan, Busan, Nagasaki, Haiphong and so on.

Most of the counties and cities with a population of less than 300,000 are classified as fifth-tier cities.

This is the rough division, but it is not absolute.

For example, Shenzhen, next to Guangzhou, has a population of less than 2 million, but its economy is very developed and can be classified as a second-tier city.

Another example is Saigon, which has a population of more than 2 million. Because of its average economic development, it can only be classified as a third-tier city.

In Dahua, there are 40 cities above the second tier.

In other countries, there are no second-tier cities.

Paris and London, which are relatively prosperous, can only be considered third-tier cities according to Dahua's standards, and they can't even get into the top 40 in the world.

In fact, the current Dahua can basically represent the world.

If you make a list of cities, population, economy, resources, weapons, etc., you can find that almost all of them are majestic.

It gives people the feeling that there is only one country on this planet.

For example, Yongxing's movie box office list for 17 years.

From the first to the last, all Chinese-language films were shot in the Central Plains. The directors and actors were almost all Chinese.

The French are famous for their romance, but without money, they can't play in the film industry, so they can only continue to introduce Dahua movies for entertainment.

In order to understand Dahua's movies, many people have to work harder to learn Chinese.

Another example is the ranking of global steel production companies.

From the first to the last, they are all Dahua enterprises, nothing else in the world.

The longest railway ranking, the longest canal ranking, the largest power station ranking, the most powerful weapon ranking...

Whenever they see these rankings in the newspaper, those foreign patriots want to tear up the newspaper and look upset.

But Chinese people look at these rankings with gusto.

Even, they will not compare with foreign countries, but compare their province with other provinces in Dahua.

Compared with foreign countries, it loses status.

In fact, foreign countries are not completely useless. Some of them could have been on the list, such as the famous scientist rankings.

However, these people, without exception, have become Chinese at this time.

Without Dahua nationality, they are not qualified to participate in the most advanced scientific research fields.

Therefore, whether these scientists are happy or not, they can only join Dahua.

The only field in which foreign countries had a chance to be on the list was also ruthlessly stifled by Dahua.

Many of these scientists who joined Dahua are celebrities in the original time and space.

For example, the mathematician Fermat who put forward Fermat's theorem, he was almost dying at this time in the original time and space, but because of the rapid development of Dahua's medical technology.

As a result, the sixty-five Father Fermat is still alive and kicking, and from time to time he can still put forward a conjecture that makes people want to flatten him.

There is also the famous Boyle. In the original history, Boyle defined chemistry as a science and separated it from alchemy. He was the founder of modern chemistry.

But now, his achievements are not that high. Wu Changqing, the wise emperor of God, who knows everything and knows everything, has long defined chemistry as science.

However, it is gold that always shines.

After Boyle learned more advanced chemistry knowledge in Dahua, he is now studying more profound things. He is already exploring radioactive materials and robbing Marie Curie of the job.

Others include Huygens, Hooker, and Newton.

Today, Newton is only 22 years old, but he is already showing his talents.

After the surrender of Great Britain, Newton was also taken to Nanjing.

Today, he is studying the question of time and space.

No way, the laws in classical physics have been summarized by Wu Changqing, there is nothing Newton has to do.

After Newton finished the courses in the university, his knowledge point has reached the principle of relativity, the principle of the unity of macro and micro.

In this regard, Wu Changqing has actually already given a conclusion, even including the proof process.

However, because it is too esoteric, many people look confused. Only a small number of people are studying these theories and exploring the application of these theories in reality.
