A large number of northerners immigrated to Nanning.

China is a country with a large land area, and China has a land area of 9.6 million square kilometers. However, we often divide the region into north and south, but seldom distinguish between east and west. In many people's minds, there are only northerners and southerners, and there are no orientals and westerners. We can study it from a historical perspective and analyze it from a geographical position. After all, in China, the difference between the north and the south is still relatively large, and the difference between the east and the west is not obvious compared with the former, so people in the north and south say when dividing areas.

1. Differences caused by historical environment In ancient times, China was a country without unification. In a very early period, many small tribes were scattered in the Yellow River and Yangtze River basins. With the continuous development, all dynasties were distributed on both sides of the river. Therefore, in ancient China, due to the geographical environment, wars often occurred between the southern countries and the northern countries, resulting in the north-south opposition and racial opposition, so there was a difference between northerners and southerners. And in the Northern Song Dynasty, large-scale immigration activities took place. At that time, the national economic center shifted from the north to the south, and the population also shifted, so there was a distinction between the north and the south.

Second, the geographical environment causes division. If the north and south are divided from the topographic point of view, the Qinling mountains are the main ones. Qinling is an east-west mountain range, so a fence is formed, which just separates the north and south sides. Moreover, the earth rotates around the sun at the same time, so there is a great difference between the north and the south in climate. Different direct points of the sun lead to different temperatures. Therefore, in the same season, the climate changes greatly in the north and south, so the living habits of the north and south will also change, so there is the saying of southerners and northerners. There is not much temperature difference between the east and the west, so there is no need to divide. China has a vast territory and rich natural resources. Of course, people have different lifestyles in different environments, thus forming cultural differences between North and South. We should also respect the environmental differences in different places and treat them with a peaceful attitude. Although southerners and northerners have some differences, they can understand each other.
