The Origin of Agriculture in China;

China is one of the centers of agricultural origin in the world. The origin of agriculture in China can be divided into two sources: one is the origin of rice cultivation with the middle and lower reaches of the Yangtze River as the core and rice cultivation as the representative; The second is the origin of dry farming in the north, which is distributed along the Yellow River basin, represented by the cultivation of millet.
