Yesterday I went to my uncle's house and found a childish A4 paper fish hanging in the middle of the entrance hall. Obviously, it was drawn by my cousin's elementary school son. About thirty years ago, my uncle nailed my cousin's failed exam report to this wall, making it known to the whole village. However, the humiliating education did not work, and my cousin is still mediocre. This drawing reflects the difference in educational concepts between two generations.
