I really like the terms "proletarian intellectuals" and "question writers". There are many intellectuals who may have certain academic status and social influence, but in the final analysis they are just mediocre people with "knowledge but no insight". The concept of "question maker" is similar. In essence, they lack the ability to perceive the truth and can only output standard answers. But unfortunately, the truth in the world is often not a standard answer, and there is no standard answer. Judgment is important.
