Student and parent controls include the child’s gender, age, only-child status, boarding-student status, adjusted self-rated health, mental development, time spent playing online games, guardian’s education, parent’s occupation and family economic status. Correlated effect controls include class size, head teacher’s career duration, gender, education, professional job title and age. Standard errors are clustered at the class level and reported in parentheses. The weight of the inclusion is 1/sample. Significance: *** p < 0.001, ** p < 0.01, * p < 0.05
