Mr. Zhu Guangqian, a master of aesthetics, with his profound humanistic quality and exquisite writing sensitivity, convincingly expressed the necessity of careful use of words and the need to develop good habits of paying attention to pondering in writing and reading with a large number of accurate language examples in his short article Chewing Words. The author thinks that Guo Moruo's example of changing "you have revolutionary demeanor" into "you have revolutionary demeanor" seems inappropriate. He also thinks that whether Han's "knocking" is better than Jia Dao's "pushing" is debatable. In this regard, the author tells a convincing truth. This innovative spirit of independent thinking and seeking truth from facts is the essence of the quality education we are carrying out today, which is very worth learning by students. The author is disgusted with the "set-board reaction" and thinks that "if a person's psychological habits always tend to set-board reaction, then he has nothing to do with literature and art", and "set-board reaction" is a common problem of many students.
