⇒ With the unbalanced development of the global economy, millions of left-behind children exist and tend to increase.⇒ The physical and mental health of left-behind children globally need more attention and should not be neglected.⇒ Poverty and inequality are the fundamental causes of left-behind children, and the widening gap between rich and poor has increased the number of left-behind children.⇒ Solving the problem of left-behind children needs support from the joint efforts of the government, parents, schools and society.
