Why did China s ancient territory expand to the northwest instead of Southeast Asia?

The main reason why China did not conquer Southeast Asia at that time was that because there was no very good level of medical care in ancient times, the local people were accustomed to the climate of the Central Plains and were not suitable for survival in the climate of Southeast Asia. So at that time, these dynasties did not want to conquer Southeast Asia, mainly because they were afraid that even if they conquered Southeast Asia, they would not be able to govern Southeast Asia better. When soldiers at that time went to Southeast Asia, they often had problems with adaptation.

However, the climate in Southeast Asia is very different from that of China. Because many parts of Southeast Asia are in the tropics, in this environment, the amount of organic matter is very large, so there are also a lot of microorganisms. There are likewise several large rivers that flow from north to south in these areas.

This situation shows that although the climate is very hot, there is also a lot of precipitation. In this case, harmful insect eggs such as mosquitoes are produced. <>

Life in the mountains of Southeast Asia is far better than life in the plains of Southeast Asia. Because there is a certain slope in the mountainous area, it is not easy to form stagnant water. However, in the plains, the slope is relatively small, and when it rains heavily, the water cannot be drained out, and there are many places where water accumulates.

These large areas of stagnant water, if left untreated, can turn into swamps and mosquito nests. At that time, if humans did not have advanced medical technology and forcibly exploited tropical rainforests, it would definitely cause many infectious diseases. So, taking these factors into account, those ancient territories would not have expanded in Southeast Asia.

Of course, the main reason is that the medical level is relatively backward, and these soldiers in ancient times could not adapt to the climate at that time. In fact, in addition to the Chinese who cannot adapt to the climate of Southeast Asia, there are some locals who cannot adapt to the local climate. Especially in the Ming and Qing dynasties, when medical technology was relatively backward, there was no effective medicine to treat malaria, a tropical disease, and it was difficult for the Central Plains people to live once they arrived in Southeast Asia.

Because China's foreign countries are mainly land, the Silk Road in the northwest region is the main one, so the Silk Road is the goal of expansion, the terrain in the northwest is flat and suitable for rule, while the Southeast Asian region is rugged, the mountains are high and the forests are dense, the economy is backward, and it is difficult to implement the county system, so it does not occupy Southeast Asia and South Asia.

Southeast Asia is blocked by the Himalayas and cannot be expanded, while the northwest region is inland, the terrain is flat, easy to control and manage, and the expansion to the northwest is also to open the Silk Road and increase cultural exchanges with the West.

Because the foreign ** in ancient times was the Northwest Silk Road based on land routes, it was necessary to expand the northwest territory. The climate in Southeast Asia is hot and humid, which is not suitable for human habitation.

Because the southeast of China is a coastal area, and the shipbuilding technology of ancient China was not very clever at that time, so it did not develop in the southeast direction.

Development of sensitive scum.

This is the territory of the Warring States Period, and we can see that the south has just reached the Sichuan region. Not to mention the two Guangzhou, the southern tip of Hunan and Fujian has not arrived.

Looking at the southern territory of Ming Mo Mo Cheng Zu Beiqiao when he was quietly felling, we can see that it has reached the border of present-day Vietnam.

It's just that the south is also very difficult to develop, with many mountains and jungles, so it is also difficult to control, and it is not much better developed than the north. So even to the south, the territory did not expand much.

What you say is completely inconsistent with the facts!

Do you think that Guangdong and Guangxi were the territory of our country at the earliest?! Come on! The Qin Dynasty barely had two Cantons (and northern Vietnam).And this possession is not yet a stable rule, but there is a city (such as Guangzhou), which is surrounded by a hundred miles of white land and nothing.

In fact, it was not until the Tang Dynasty that Fujian became a Han land, and five generations later, when the Song Dynasty began, Liangguang became a stable Han land. However, Vietnam successfully broke away from the Central Plains because of various problems during the Five Dynasties and Ten Kingdoms period, and the Ming Yuan Dynasty was once involved but finally had no choice but to give up. As for Yunnan in the southwest, it was the beginning of the Ming Dynasty, and after the Duan family, the hail was quietly buried in the state to achieve stable rule!

Therefore, China's operation of the south in ancient times has been gradually promoted.

The current China is not the previous China, to be precise, the current China is the result of the development of infrastructure, there were no railways, there are no steel bridges, and even floods are difficult to solve, those places in Guangdong used to be seriously flooded, and belong to the border land, belong to the place where the prisoner is put away, and the expansion of territory is not a simple thing that you want to ok.

The other is the difference between the north and the south, just like you southerners don't understand how cold the winter is in the northeast, the north is dry and the south is hot and humid, the climate of the plain and the high resistance to the original are different, not to mention the language, culture, customs and climate are different from a group of people, the core area of Chinese culture has been in the Central Plains, before the rise of sea power, the land power of China is generally in Henan and other northern regions, on the one hand, because of the climate (not too cold, not too hot and stuffy), on the other hand, the land of Qilu has always been composed of Chinese cultural halls.

The Nanshi tribe is a tropical rainforest, like today's Suiyou Amazon rainforest, full of plagues and infectious diseases, and the mountainous areas are full of old people, there is little arable land, and there is little room for development.

Only when the north cannot survive because of the war will it find a way to expand to the south.

In ancient China, it was actually more difficult to deal with in the north, so developing to the south can also develop its rivers and lakes.

It's also hard for me to develop in the south because the climate in the south is very difficult to adapt to. And I'm not very familiar with the quality and environment on that side.

In ancient China, it was true that the north was more difficult to deal with, so in most cases, it was more appropriate to expand to the south.

In ancient China, it was difficult to deal with the north side, so why not develop the river soil in the south? In ancient times, it was similar to Guangdong and Guangxi, and I think this situation is mainly due to the fact that there is more sea water in the southern region, which limits the opportunities for expanding the peina.

In ancient times, China's territory was very vast, there were relatively rich areas and uninhabited areas, and it was precisely because the territory was too vast that it was difficult for the emperor to directly control many places. Some people will ask why ancient China preferred to control the Western Regions instead of the more fertile Southeast Asia? The answer is that the Western Regions region is far away from the center and difficult to control, and the Western Regions are different from Southeast Asia, so the knowledge level is relatively small compared to Southeast Asia, so it is difficult for the Central Plains to be infected and to achieve the unity of thought.

The Western Regions are from China's Xinjiang region or above Xinjiang, which is relatively far away from the Central Plains, and its economy is relatively backward compared to the Central Plains. The cultural aspect is also less affected by it, so most of the country's energy is spent on managing the Western Regions. But Southeast Asia is different, Southeast Asia is a tropical region of our country, the climate is hot but suitable for the growth of tropical plants, and Southeast Asia is rich in water resources, so it is also relatively powerful in agriculture. <>

It is precisely because of the convenience of water transportation that business is more frequent, and the frequency of business leads to the flow of many people, and exchanges are also more frequent, which is that Southeast Asia is more seriously affected by sinicization at the cultural and ideological level, so Southeast Asia is relatively easy to manage, and people are also very cooperative; Compared with the Western Regions, the Western Regions are far away from the management center, and they are relatively less influenced by the Central Plains at the cultural and ideological level, so it is relatively difficult to manage. <>

Although the Western Regions are relatively backward compared to the Central Plains in terms of economy, culture and ideology, there are many rare treasures in the Western Regions, most of which come from the Western Regions, and the Western Regions are also relatively rich in natural resources. In addition, there have been many beauties in the Western Regions since ancient times. The above is basically one of the reasons why the Western Regions are being fought for and managed.

First, because the Western Regions is a fortress of strategic deployment, effective governance is of great significance to resist foreign aggression; Second, it is conducive to properly handling relations with ethnic minorities in border areas and safeguarding national unity and stability; Third, the Western Regions region is vast and rich in resources; Fourth, there are many countries in the Western Regions that are adjacent to each other; Fifth, Southeast Asia is farther away from the rulers of the Central Plains than the Western Regions.

Because the development of navigation technology in ancient times was relatively slow. To get to Southeast Asia, you need to pass through the ocean. And the Western Regions can be passed directly from the land.

Because Southeast Asia was not as rich as it is now, and the Silk Road was created in ancient times, which could facilitate the flow of goods.

Because the west of the Qing Dynasty was relatively fertile, they did it for the sake of economic development.

Because the west is land, it is easy to expand and conquer. And Southeast Asia needs to fight a naval war, and the naval equipment of the Ming and Qing dynasties is not very advanced, so it is difficult to expand.
