This paper uses a random sampling method to conduct a questionnaire survey of 3,000 older adults aged 60 years or older in Nanjing and a dichotomous logistic regression model for empirical analysis. The two dimensions of mental health and social adjustment were used to measure the mental health status of the elderly.

From the perspective of practice, including participatory observation and case study method, this paper analyzes the situation of 71 migrant children in order to improve their extracurricular life quality by social work intervention. In the short term, project members have generally developed good study habits.
