Weather in Baiyin Pingchuan, Ningxia
Second, the birthplace of culture and the original proportion of historical population determine that the north has become the capital center of successive dynasties. As we all know in history textbooks, the cultural origin of China is the Yellow River Basin, followed by the area north of the Yangtze River. The Yellow River basin belongs to these places in the north, and there are many fertile fields for northerners to live and grow food. This initial cultural origin and population distribution are doomed, and the north will become the first choice for the economic center and capital construction of dynasties. If you want to move the population from the north to the south to build the capital, not only the human and material costs are immeasurable, but also the ethnic minorities in the south are facing a very difficult problem. In addition, the south has a small population and must take care of the majority, so it chooses to build its capital in the north.
Third, the northern terrain is easier to resist foreign enemies, while southern Ma Pingchuan has no comparative advantage. There are hilly and mountainous terrain and a large number of dense jungles near the Yellow River, which can effectively build the capital and use the terrain to resist foreign invasion. Ma Pingchuan is in the south, and there is no terrain suitable for the dynasty to avoid danger. On the other hand, all previous dynasties attached importance to the direction of external expansion. The direction and area that the capital can expand in the north can radiate to the whole country, while the capital in the south can only face a wider plain.
