Because for some very remote rural areas, it is a big expense for children to go to school. Perhaps some rural areas are still worried about their livelihood and feel sorry for every place in life where they spend money. Although nine-year compulsory education has reduced children's tuition and book fees, children still need other expenses to study in these nine years. For poor families living in difficulties, school supplies and reference books are still a very big expense.

And children in rural areas also have their own ideas. Some people may not like reading, and sitting in class is also a waste of time. Reading is useless to them. They hate reading from the bottom of their hearts. There are also some children who like reading very much, but family conditions really can't support them to study. For them, life is already a very difficult thing, and reading is a heavy burden for them. Children from poor families always need to take care of themselves early. They should consider their own families, not just themselves. So for the sake of their families, they have to give up their favorite studies and shoulder the burden of life early. Step on the pace of the older generation, choose to face the loess and go out to work, and provide some help to the family.

Part of the reason is ignorance of farmers' thoughts. They think it useless for children to study. Instead of spending nine years away from home to study, it is better to spend nine years working outside or doing farm work for the family to get more direct economic benefits. This is their "right path". It is also a very sad thing. Their short-sightedness has cost children a lifetime.

This is why many rural children choose to drop out of school after nine years of compulsory education.
