Don't Push Me, I'm Just an Ordinary Teacher

Go back to 20 years ago and become the only "full grade" teacher in the world? It sounded great, until he discovered that his colleagues couldn't even understand the lectures. Seeing that the flowers of his motherland were about to grow into leeks, he sighed and had no choice but to leave the mountain "reluctantly". By accident, he taught the top class; by accident, the textbooks he compiled became national standards; by accident, he changed from a hard-working teacher who fainted after working overtime to a well-known big shot in the education world. Faced with the media's pursuit, he just wanted to say: Don't ask, just ask for basic operations. (The content is purely fictitious, please do not take it seriously!)
