Agriculture, commerce and cities in the basin are developed, and the basin is the economic center of this civilization. The ancient river basin is characterized by agricultural civilization, and agriculture is the most important production department in these areas. The Nile Valley, the Two Rivers Valley, the Indus Valley, the Ganges Valley, the Yellow River Valley and the Yangtze River Valley are all ancient developed areas, and agriculture is the economic basis for the formation and development of countries in these areas. Asian and African civilizations such as ancient China, ancient Egypt, ancient Babylon and ancient India were established and developed on the basis of agricultural economy, and showed their own civilization characteristics.
The great river civilization was born in the great river basin. These areas are rich in irrigation water, flat terrain, relatively fertile land and mild climate, which are suitable for human survival, conducive to the planting and growth of crops and can meet the basic needs of people's survival, so agriculture is often very developed. River civilization is based on farming economy and highly depends on the natural environment. Farming economy is a peaceful and self-sustaining economy, and the national psychology derived from it is also defensive. The Chinese nation, as a typical river civilization, rarely acts of expanding its territory and invading. The construction of the Great Wall is the best embodiment of China people's national defense thought. The Great Wall, with no offensive nature, focuses entirely on defense. For a long period of history, Chinese civilization once led the world civilization, especially the achievements in textile, shipbuilding, porcelain making, paper making, printing, gunpowder, construction and other industries, which once left all countries in the world behind. Dahe civilization created splendid and lasting feudal culture and maintained long-term political and political stability.
