First of all, what is the purpose of education? There is no doubt that excellent adults will be produced, so that children can better adapt to society and gain stronger working ability. Can this be brought by playing?
Secondly, the so-called liberal education is actually quality education in China. What is "quality"? It is difficult to define, and the method of cultivating quality is very expensive. Oral English teaching and musical instruments are very expensive to cultivate these hobbies. What is certain is that the quality of children in big cities is generally higher than that in rural areas. If grading by quality will not only lead to corruption, but also make the distribution of educational resources more extreme, leading to poorer and poorer, richer and richer, and poor children will never turn over.
