From the analysis of the fourth paragraph, we can see that the Japanese have a national character that is afraid of change. If we look at the narrative logic behind this national character from another perspective, we can find that they also affirm the weakness of people. This is logical.
When "change" becomes something popular database that cannot be overcome by oneself, then only by believing in the weakness of human beings can rationalize one's stagnation. They believe that human beings are weak and powerless, they believe that people cannot change their destiny, and that they must all submit to something. However, when there are people who want to change, such a society will not lend a helping hand to them, but will.
suppress those who intend to reform with all aspects of oppression and blows, in order to force them back to meet the expectations of "weak" in the frame. There is no other reason for doing this, but to maintain the "rightness of the weak" that he believes in, to maintain the correctness of his weaknesses, and to try to "change" as the right person, he will be excluded.
