According to authoritative surveys, there are more than 58 million "left-behind children" in rural areas of China. 57.2% of left-behind children go out with one parent, and 42.8% go out with their parents at the same time. Among the left-behind children, 79.7% were raised by grandparents, 13% were entrusted to relatives and friends, and 7.3% were uncertain or unsupervised.

Most left-behind children are taken care of by grandparents, and the lack of parental supervision and education has a negative impact on the all-round healthy growth of left-behind children. The problem of "intergenerational education" is the most prominent among the "left-behind children" groups. The problem of left-behind children is a unique social problem in China's modernization process and another obstacle to the construction of a new socialist countryside, which seriously affects the healthy growth of left-behind children and has attracted the attention of the whole society.
