This phenomenon of "involution in education" stems from the close relationship between excessive and disorderly educational competition among provinces, cities, schools, grades and classes. As one of the main battlefields of this involution phenomenon, "parent group" has become a tool for teachers to assign "tasks" to parents.
Sadly, everyone knows that this phenomenon is not good for anyone, and everyone is struggling from it. Even some parents make irrational withdrawal from the parent group, and no matter how hard they struggle, they can't get out of the competitive pressure of "involution".
