In order to have a boy, a family gave birth to more than one child. In order to avoid getting into trouble, they fled to other places to live, leaving their eldest daughter at home to be raised by their parents. The girl has been living alone with her grandparents because her parents are not around. Life is not too hard, but there is no surplus. In addition, without good study habits, you can't continue your studies after graduating from junior high school. It didn't take long to fall in love, get married and have children. Now at an early age, the child is already very old.
If she is raised by her parents, she may get into the habit of gambling, because her father is such a person. Although grandparents cannot provide a good environment, at least there is no such atmosphere at home. Although children don't study well, they have no other bad habits.
Someone in the village died when he was a child and his mother remarried. He and his brother were brought up by their grandparents. When they were in school, they didn't study hard, and they weren't students with particularly bad habits except general study. Now they are married, driving excavators, contracting some projects, living well and being filial to their grandparents.
The above two examples just want to show that intergenerational education cannot be easily judged. They have both good and bad points, which can't be summarized in one sentence.
