As we all know, the north and south of China are bounded by Qinling Huaihe River. Although there is a big gap between the north and south of China, there are many transition areas on both sides of the Qinling Mountains and Huai River, so there are not very abrupt differences.
is similar to China. Vietnam is also divided into north and south. Because Vietnam itself is divided into three major regions, north, central and south, the central region is narrow and long and has a low population density, while the south and north are both densely populated. Therefore, the gap between the north and south of Vietnam is extremely large, and they are more than 1,000 kilometers apart, which is even better than China.
The north and south of Vietnam are not only far away, but also have no transitional areas in the middle, and belong to two geographical areas with one side of the sky.
Comparison between the north and south of Vietnam and the north and south of China
Although China and Vietnam have the concept of north and south, a significant difference between the two is that northern China to the south belongs to a "gradual" process, with a larger transition in the middle. Vietnam has a "mute change" from the north to the south, and the transition effect of the narrow and narrow areas in the middle is not great.
Qinling and Huaihe River is the dividing line between the north and the south of China, and the north and the south of China are shown in the figure.
The north and south of Vietnam are shown in the figure, and there is also a narrow and narrow area of Vietnam central .
Vietnam actually has its own core: the core of northern Vietnam is Red River Plain , and to the north, it is the mountainous areas in the northeast and northwest; the south of Vietnam is all plains, that is, Mekong River , The area of the estuary of the of the Saigon river.
The picture below is the Red River Plain in northern Vietnam.
The following picture shows the Mekong Delta in southern Vietnam.
Although northern and southern Vietnam are both located in hot spots, they themselves have great differences: the river network in the south is thinner, denser, and more, with a kind of "the characteristics of water life", and the Honghe Plain principle in the north has relatively Large continuous area.
The south and north of Vietnam are extremely far apart
Vietnam is a narrow and narrow country. Judging from its two central cities in the south and north, the distance between them is already very far, reaching about 1135 kilometers.
The map below shows the distance between the two major cities in the north and south of Vietnam.
From the picture, it can be seen that the north and south of Vietnam are not only far apart, but also pass through two neighboring countries at the straight line distance, not in Vietnam.
The distance between north and south of Vietnam is more than 1,100 kilometers. Even in China, where the land area is vast, it is still a very long distance. The distance between the three groups of cities in north and south China is shown in the figure below.
0 The two major cities in north and south of Vietnam are 1135 kilometers apart, which can be compared with some distances in China.
1 Eastern China: Dalian City is a northeastern city, Ningbo City is a southeastern coastal area. The populations of the two are very different, but they are only about 1,000 kilometers apart - two major cities in north and south of Vietnam. Nearly 100 kilometers;
2 Central China: Hohhot City is a northern city outside the border, and Wuhan City is a plain city in the middle reaches of the Yangtze River in southern China. The two are separated by Shanxi and Henan, but the distance is only 1,150 kilometers - from north and south of Vietnam The distance between the two major cities is equal.
3 Western China: Lanzhou City is a land-covered city, Kunming City is the southwest province. The two are separated by the Qinling Mountains and the entire Sichuan Province. The distance is only 1,250 kilometers - two larger than the north and south of Vietnam The city is only 100 kilometers more.
It can be seen that compared with Chinese cities, the 1135 kilometers distance in the center of north and south of Vietnam is still very far away.
The two photos below are scenes in northern Vietnam.
The following two photos are scenes in southern Vietnam.
The origin of the north and south of Vietnam
In the historical geography of Vietnam, it is also divided into three major regions: north, central and southern regions, the same as the current geographical partition of Vietnam.Historically, Vietnam was divided into different geographical and geographical environments, and northern Vietnam is naturally far away from the south.
Below is the situation of Indochina Peninsula in the French Indochina period.
During the French Indochina period, Vietnam was divided into three major regions:
1 The northern part of Vietnam is called Tokyo (Tonkin), and its capital is Hanoi ;
2 The southern part of Vietnam is called Cochinchina (Cochinchina), and its capital is Sai Kung ( Ho Chi Minh City );
2 The northern part of central Vietnam is called Annan , and its capital is Hue. Although this place is large in area, its population is low, and its overall population is smaller than that in the south and the north.
Due to the vast area of central Vietnam, the northern and southern Vietnam, which are more than 1,000 kilometers apart, naturally appear even further away.
To sum up, although Vietnam has a similar concept of "north and south" as China, Vietnam's fields are actually divided into three regions: north, central and southern. Because the central part is very narrow and long, the north and south of Vietnam are basically two separate geography. area.
If the north and south of China are just separated by the Qinling Mountains and Huai Rivers, there are some transitional areas between them. The north and south of Vietnam are two densely populated areas that are thousands of miles apart. Even in China, their distantness spans several provinces and one side of the north and south.
