In recent years， it has become a common trend for peasant families to buy houses in their hometown counties in the central and western regions， which has greatly accelerated the process of county urbanization in this region. From the perspective of farmers’ life， This trend stems from multiple factors such as limited family payment capacity， family values and rural traditions， regional marriage competition， children’s education needs， and policy guidance of county-level governments. After moving to the city， the change in the overall goal of peasant families has shaped a new family form called“one family， three systems”， which includes family structures spanning across cities， counties， and rural areas， a division of labor between part-time work， farming， and accompanying children’s education， and a family order that balances accumulation， security， and development functions. The“three systems for one family”is a new practice adopted by peasant families in the central and western regions in response to the pressure of modernization， transforming peasants moving to the cities into “dual residents” with elements of both county towns and rural areas. This duality breaks down the geographical boundary between“city”and“rural area”，and has the potential to promote the development of higher-quality urban-rural integration， but it also carries certain family and social crises. Accordingly， it is suggested that dual residents should be regarded as the focus of policies to promote new urbanization and rural revitalization， and favorable conditions should be created for them to play an active role by means of gradual urbanization policies， reasonable determination of county industrial construction positioning and goals， and overall spatial layout of county public services.
