First, economic capacity does not allow it. The post-90s couple live in the mountains. Before that, the man will go out to work to earn money to support his family. But later, because his parents were too old to take care of the elderly at home, they had to live on a minimum living allowance of more than 4,000 yuan per month. They think that this money can stabilize their lives, so they don't have much expectation for life. But they didn't consider that their children would go to school in the future. If these children want to be as fair as other children, they must go out of the mountains and receive a good education in order to succeed at an early date. But with the couple's thoughts and their living conditions, they are unable to create a good education and a good life for these children.
Second, it cannot be treated fairly. The couple had nine children, which means that the oldest child is at least nine years older than the youngest. This age gap does not allow parents to treat their nine children fairly. In many families, two children can't be treated equally, let alone a family of nine children. This is unfair to older children. If they are treated unfairly since childhood, they are likely to distort their minds. The best education for children is family, but these two couples didn't educate their children well. They let their children grow up in a sloppy state, so it is difficult to receive a good education.
The couple's thoughts are still very traditional. They think that only having children can make them happier, which will mislead future generations. Unless their descendants can walk out of the mountains on their own, it will be difficult to receive a good education and live a good life. They may continue to have children in the mountains like their parents.
