What would happen if the left-behind children live apart from their parents for a long time? Do left-behind children evidence lower Social Information Processing skills and appear to be more aggressive than children in rural areas who live with their parents? “Let’s be friends” research team conducted a scientific trial at Jingyang Country from Shaanxi Province to answer these questions.
