In the past 30 years, China's economic reform has been successful, but the regional gap and the gap between urban and rural areas have made China fall into the confusion of fairness. In this episode, the documentary shows us the gap between urban and rural education in China and China. Rousseau, a great thinker, said, "Education is a great tool to realize social equity." Confucius in China advocated that education should not be divided into classes. Therefore, education needs fairness. But it feels really, really hard to be fair and just. Economic development has improved human life and quality of life. However, the economic development itself is unbalanced, so it is really difficult to implement Deng Xiaoping's system of getting rich first and then getting rich together. The economy is still like this, not to mention the fairness and justice of education, but we still need to work hard.
