The quality of education is balanced, and the main indicators are educational resources, school conditions and teacher resources. There seems to be no correlation between the two. But the essence of education balance should be high-quality balance, because the balance without quality guarantee is inefficient. If there is no high-quality school education as a guarantee, and the performance of educational balance is only at a lower level, there is no difference among all schools, then balance will lose its meaning, and it cannot be regarded as the characteristic of high-quality education, let alone advocated and pursued by educators.
