However, what you've said seems important enough to discuss. School should be the most comfortable place for children outside of home. Education aims to produce students who not only possess broad knowledge but also possess strong reasoning skills, creativity, and initiative.

However, this will not be achieved if the quality of educational institutions and educational staff is considered poor and substandard.
