With the accelerating of urbanization and industrialization, millions of surplus peasants move to cities for working. How to let these peasant-workers integrate into cities and become members of cities has become a hot topic for all fields of studies and many scholars make studies on how peasant-workers are excluded from cities from the angle of social exclusion. The author thinks that the key for peasant-workers to successfully integrate into cities is how to adapt the living of cities, including professional adaptation, living adaptation, public relation adaptation, psychological adaptation, and so on. However, the factors that influence the adaptation of peasant-worker mainly include institutional barrier, cultural barrier, social exclusion, as well as low cultural quality, weak right protection consciousness, improper behavior and attainment and so on. Thus, the adaptation of peasant-worker can be solved from such three perspectives as national level, urban level and peasant-worker level.
