Chinese civilization is based on its own agricultural development. In terms of animal husbandry, the southern rice planting pattern, which is adapted to the settled agriculture and developed in the mutual exchange and collision, has formed a pattern of coexistence of agriculture, animal husbandry and hunting, and has different origins based on the differences in natural conditions and social traditions. Primitive agriculture in most areas of China directly occurred in gathering, fishing and hunting economy.
