The paper by Liang and Sun (2020) titled "The Lasting Impact of Parental Migration on Education and Health of Children in China" investigates the effects of parental migration on the educational outcomes and health of children left behind in rural areas of China. Here are the key points from the paper:

**Background**: The study focuses on the phenomenon of parental migration, which has become prevalent in China as parents seek better economic opportunities in urban areas, leaving their children in rural communities.

**Educational Outcomes**: The authors find that children with parents who have migrated tend to have lower educational attainment compared to those whose parents remain in the home community. Factors contributing to this include emotional and psychological stress from separation and reduced parental involvement in their education.

**Health Impacts**: The paper highlights negative health outcomes for left-behind children, including higher rates of mental health issues and physical health problems. The absence of parental care and support is linked to these adverse health consequences.

**Socioeconomic Factors**: The study emphasizes that socioeconomic status plays a crucial role in mediating the impact of parental migration on children's education and health. Families with lower socioeconomic status face more significant challenges and risks.

**Policy Implications**: The authors suggest that policymakers need to consider the welfare of left-behind children when formulating migration and labor policies. Support systems, such as community services and interventions, are recommended to mitigate the negative impacts of parental migration.

**Data and Methodology**: The paper employs a robust dataset and various statistical methods to analyze the effects of parental migration, ensuring the reliability of their findings.

Overall, this research sheds light on the complex dynamics of parental migration in China and its significant implications for the well-being and development of children left behind in rural areas.
