In the mid-Northern Song Dynasty, under the background of the land policy of "not suppressing mergers" and the prosperity of the commodity economy, they grew from poor farmers who rented land from landlords to "new landowners" who owned fertile land and promoted the development of their neighbors. In the game of land and market, they understood that "farming is not only a living, but also the survival wisdom of taking care of farming and integrating into the market", and completed the growth and transformation from "dependent" to "self-reliant".
