In this paper, based on three aspects （the educated, the subjects implementing education, and external environment）, the main factors restricting the entrepreneurship quality education for the young peasant workers back to hometown in Yunnan province are analyzed, and also the governmental strategies of a clear purpose and a powerful applicability are further explored.展开更多
