The local peasant undergoes the process of class differentiation within rural village. From the 1980s onwards, they are under the pressure of proletarianization. They lost farm land and advantages in local market. These transformations change the social division of labor in rural village. The only way against this process is the expansion of village government and its administrative power. The need of strengthening security force leads to more recruitment of young people. It mitigates the pressure of proletarianization and forms the basis of the local society.
