Oh, this is an interesting question. China's rural areas, that is, rural areas, take agricultural production as the main industry. Naturally, their formation was gradually formed when humans learned to farm and began to settle down. Its history can be traced back to tens of thousands of years ago, and it is called the emergence of primitive farming. The middle and lower reaches of the Yellow River with Henan as the center is called the Central Plains region or the core region. People began to learn to grow grain and domesticate livestock, and then got rid of the wandering life of collecting fishing and hunting and began to settle down, resulting in primitive farming settlements, which gradually evolved into today's countryside and cities.
