There is no involution. Zhengzhou 18th United International School was approved by Zhengzhou Education Bureau in 2008 and founded by ProChina. Zhengzhou 18th United International School does not participate in the examination. The school refused to intervene in the exam, and the principal asked the teachers to "get rid of the phenomenon of leapfrog intervention in teaching." The "anti-involution" education in Zhengzhou 18th United International School has also become one of the reasons why more and more parents choose 18th School.
