After the news of C9 League in senior high school was released, it aroused concern and interpretation, and some people were worried about "monopoly of high-quality resources".

A parent who has experienced the senior high school entrance examination for children said that the 50% diversion rate of the senior high school entrance examination, the brutal competition of local high schools and "pinching people" made the senior high school entrance examination more anxious for parents than the college entrance examination.

Regarding the practice of establishing C9 alliance in the above-mentioned high schools, he thinks that there are too few samples at present, and they are all top high schools. Solidification into C9 alliance will have a long-term and far-reaching impact, such as labeling, high-end and exclusivity. At the same time, he also questioned the view that "high-quality educational resources" cooperate with each other, rather than "educational resources" are balanced.

Chu Zhaohui, a researcher at China Academy of Educational Sciences, told Zhongxin.com that high school leagues are not uncommon in China, mainly to gain an advantage in the competition. He said that at present, there is a ladder structure among high schools in China, and it is even more necessary to speed up the balanced development of education and narrow the differences between schools.

"Relative balance is relative dynamics." Chu Zhaohui believes that the high school C9 Alliance schools are located at the top of the cascade structure. Generally speaking, all localities should grasp the scale, break the score theory and explore diversified standards, so that high school education can be in a scientific and rational benign ecological environment.

Chu also mentioned that in the past few years, someone put forward the slogan of "protecting the county". He believes that Baoxian is actually to balance the resources of high school education.

In July last year, at the press conference of the Ministry of Education, Lv Yugang, director of the Department of Basic Education of the Ministry of Education, said that it is necessary to? Resolutely curb the excessive loss of high-quality students in counties, and resolutely curb the problem of some schools competing for students across regions, especially cities and counties. This reform started from 20021,and the overall goal is to fully implement it in three years.
