We should eliminate the "psychological barrier" and the fear of "saying nothing" from two aspects. It is the most important requirement for writing to be clear and honest. To seek truth is to "have true feelings" in the work, to say the truth, to say what is in your heart, not to say lies, empty words, or to make up lies; to be honest is to "speak your own words honestly", to be honest and realistic, and to seek truth from facts. "Sincerity in the middle" can "form outside".
