Based on the background of new urbanization，this paper investigates migrant workers who go out to work in Henan Province，and uses descriptive analysis methods to analyze the stress source and the well-being of migrant workers. It is found that the well-being of migrant workers living in their hometowns is higher than that of migrant workers living in work places；the differences in well-being among migrant workers of different genders are very significant；the well-being of migrant workers in different generations is significant；but there is no significant difference in well-being among migrant workers in different marital statuses. Through the description of this paper，the performance and differences of the pressure and happiness of migrant workers can be better understood，and then the corresponding strategies to alleviate the pressure and improve the happiness can be provided from four aspects more specifically. First，reasonably arrange the working hours of migrant workers and provide them with appropriate job training. Second，raise the salary level of the dense just group，safeguard various rights and interests according to law. Third，we will improve the social security system for migrant workers and improve their housing，medical care，cultural and entertainment standards. Fourth，we will strengthen support for the elderly and children left behind by migrant workers to reduce their worries about urban construction.
