There is a great disparity in teaching staff.
Teachers are the most obvious, because the welfare treatment of township schools is very different from that of cities, so many people are reluctant to come to township schools as teachers. Although the subsidy for township teachers in China is relatively large now, once you come to a township school, it means that your life will be here in the township in the future. People without connections want to go back to big cities, and the chances are slim, so most powerful and talented people are choosing to live in big cities. Even teachers with outstanding teaching level in villages and towns will be promoted and transferred to schools in counties or cities because of their outstanding teaching ability.
Differences in educational equipment
The textbooks and teachers' salaries of local schools are not uniformly distributed by the state, but distributed by local governments. For cities with strong economic strength, more funds will naturally be invested in education, while there is no extra money in underdeveloped areas, so the investment in teaching is limited, which also leads to many township schools simply unable to afford more advanced teaching equipment.
The gap between parents' attention to education.
Parents in towns attach great importance to their children's education. In many places in towns and villages, many parents have no academic qualifications and don't know the importance of learning, so they never care about their children's education. But in cities, the opposite is true. They know that knowledge can change their destiny, and they can learn a lot from learning. Therefore, they attach great importance to their children's education and often give them remedial classes and interest classes.
