Why are China s provincial demarcation lines so complicated? Does it have anything to do with histor

China's provinces are basically divided according to mountains and rivers, which is why it is so complicated. Of course, the division line of provinces has a lot to do with history, and the current boundaries of provinces are all formed under unique historical conditions.

First of all, this is a historical reason, and the division of provincial boundaries of the ancients also has a historical heritage.

The second specific reason is the mountains and rivers, the Tang Dynasty divided the world into ten roads according to the mountains and rivers, and the dividing line between Hebei and Henan is the Yellow River.

In fact, this can be seen from looking at Shaanxi, and the division of Shaanxi is the epitome of fine division. Historically, Shaanxi was divided into three components, namely: northern Shaanxi, Guanzhong, and Hanzhong, so there are so many divisions.

In addition, in order to maintain the rule and regional checks and balances, the important areas of a certain province are divided into other provinces to avoid rebellion and rebellion, so that he cannot exist apart from the country.

The first is the principle of dividing provincial boundaries, which is wrong according to the shape of mountains and rivers and dogs' teeth. Second, it is the result of historical accumulation, including wars, historical disputes, clashes of civilizations, and other factors.

It is because the direction of the rivers and mountains in each province is determined, and the way of life of the people in each region is different, so it cannot be square.

Because the planning of the provinces has been in place since ancient times, and the boundary line between the two provinces may have complex terrain such as rivers or plate junctions, there will be ambiguous areas, so the demarcation line is tortuous.

Because China's provincial boundaries are divided according to mountains and rivers, it will be tortuous.

There are two basic principles in the division of China's provincial borders, one is the shape of mountains and rivers, and the other is the misalignment of dogs' teeth.

1. Deformation of mountains and rivers

The so-called "mountain and river shape" means that when the boundary is demarcated, it is divided according to natural conditions such as mountains and rivers. This was more common before the Song Dynasty. For example, the Qin Dynasty was divided into 36 counties, and the Han Dynasty was divided into 13 prefectures because of the shape of mountains and rivers.

As a result, the provincial boundaries of Shanxi Province were basically fixed in the Qin Dynasty.

The deformation of mountains and rivers is mostly seen in ancient times, using natural conditions to --- high mountains and large rivers to divide the area, which is easier to distinguish and is also conducive to defense, for example, Qin Land, also called the land of Sisai, it is surrounded by high mountains, four passes to guard, easy to defend and difficult to attack. It was also used as a defensive fortress when the princes were divided, and to a large extent, they took advantage of the geographical advantage to preserve the integrity of the country. Most of the current national borders are like this.

2. Canine teeth

However, if the political districts are divided in full accordance with this principle, there will be a very big hidden danger. If the region is large enough and the leaders have enough power, it will create a situation of precarious separation. In order to put an end to this phenomenon, since the Song Dynasty, when the state divided the administrative regions, it consciously mixed the sand, deliberately dividing the strategic points of the region into another region, which destroyed the geographical integrity of the administrative regions and made it difficult to divide the local areas.

This is the principle of "intertwined teeth" in the process of dividing political regions.

Hanzhong, which obviously belongs to Sichuan geographically and culturally, was assigned to Shaanxi, which is exactly the case. After Liu Bang unified China, he divided the original forces of the various vassal states, strengthened the centralization of power, and deliberately staggered the original dividing line, so that the advantages of the terrain were shared, which was not conducive to defense, and effectively weakened the power of the local separatist regime. So the provincial borders are basically like this.

It is absolutely impossible, according to this division, Hebei Province is divided into three parts, and Hebei's finances mainly rely on Tangshan, Langfang, and Qinhuangdao in the north, and Shijiazhuang and Handan in the south, and Tangshan's economic scale accounts for more than half of Hebei. If it is divided in this way, it is estimated that Hebei Province's finances will be empty.

Moreover, the topography of many provinces in our country is not arbitrarily determined. Among them, there are economic reasons, but also political ones. Politically, a lot of it has been summed up through the lessons of history, because in history, many warlords have used the terrain advantage of a province to fight against each other, so that the terrain of each province will be changed so that they can contain each other.

After many years of changes, there is now a topographic map of the provinces in Chinese mainland, so the topographic map of each province cannot be changed at will, which must meet the political and military needs of ****.

Because there are many ways to demarcate the boundaries of provinces, one is naturally formed, such as a certain river or a certain mountain range, and the other is artificially dividedBecause of our long history, many provinces are divided according to a river and a mountain rangeSo it's normal for there to be zigzag bordersAs a new country, the United States will be much less difficult to divide.

Anyone who has read a map of the world will find that different countries or different provinces have different borders, like the provinces of our country, it gives people a sense of zigzag, and there is no sense of flatnessTherefore, it is not uncommon to find that part of a province is stuck in another province, or another place is surrounded by a certain provinceAnd the United States is often a square border, the main reason is because of historical and topographical factors.

In the land of China,The terrain is complex and changeable, so some places are divided according to rivers, such as Henan, Hebei, Shanxi, and they are mainly based on the Yellow River, and Jiangxi and Fujian are divided by Wuyi MountainAnd like our country, there are complex ethnic minorities, so even if the provinces that were previously divided, there will be new border demarcations and new changes, for example, Ningxia is surrounded by Gansu and Inner Mongolia.

There are no minorities in emerging countries like the United States, and there are very few Indians leftIt is also relatively simple to divide in this way, and the terrain in the United States is not so complicatedThe main mountain ranges are concentrated in the western region, and the middle is all plains, so it is relatively easy to divideThere are many such situations in the world, such as the national borders of Europe are also crooked, and the borders of many countries in Africa are also square.

Because there are often wars on China's territorial borders, I don't want to draw lines to determine the scope like the colonies.

Because the division methods are different, one is according to the trend of mountains and rivers, the second is the division of local forces, and the third is the division of humanities.

Because China's provinces are divided by geography.

Of course not, these places have been divided a long time ago.
