What spirit did Dai Zhen show for the teenager Dai Zhen? Who is the irony of the joke Truman Invisible?

"Dai Zhen is hard to be a teacher" shows the spirit of young Dai who is good at thinking, dare to question and dare to question.

The Chu people in The Invisibility of Chu People live in poverty and can't keep their ambitions. They have evil thoughts and are blinded by interests, so they do stupid things that deceive themselves and others. Ironically, they are greedy fools who want to get something for nothing, deceive themselves and believe lies.
