Abstract: Based on the basic standpoint of acquaintance society, this research taked the villagers in XT resettlement community in Nanjing as an example by using qualitative research method, and focused on the changes of the daily interaction and social communication of the villagers after the centralized resettlement. The research shows that after the original village community is broken, the villagers daily life has changed significantly in the way of treating strangers, the purchase of funerals, the distribution of property, and the practice of general kinship, but its characteristics of defence, cooperation, competition and social interaction have not fundamentally changed, and the series of mechanisms that promote the smooth operation of acquaintances' social order still play an important role. The multiple contradictions presented in the process of local social transformation reflect the individual and group's pursuit of high quality social order in the new era.

Key words: acquaintance society, land-lost farmers, demolition, order, mechanism, Nanjing city
