How did feudal ethics eat people in Diary of a Madman? What is the significance of Diary of a Madman to modern times? How did Song Ci come into being and develop?

Feudal spirit. Lu Xun said that A Madman's Diary was influenced by Nicholas Nikolai Gogol's novel of the same name and Nietzsche's thought, but it was "deeper and wider than Nikolai Gogol's grief and indignation, and not as slim as Nietzsche's superman". The Diary of a Madman exposes and criticizes the feudal system and ethics step by step on several levels: the first level reveals the universality of cannibalism from the external environment, and then through the association with madmen, the specific physical cannibalism in history and reality is raised to a deeper level of benevolence and morality. The second level, from the perspective of the family, perspective the foundation of feudal ethics-the evil of the family system. The image of "Big Brother" is a symbol of the family system. "Big Brother" didn't mean to persecute the madman, but the ethical concept he followed decided that he must eliminate the madman's rebellious consciousness according to the will of social tradition, so he also participated in the ranks of cannibalism. On the third level, through the self-reflection of the madman, the meaning of "cannibalism" of the feudal orthodoxy has been led to a deeper and wider scope: the madman has also been poisoned by the orthodoxy and become a cannibal. In particular, I, who was described by a madman as having a history of eating people for 4,000 years, was obviously not only a madman himself, but also a "China person" dominated by patriarchal clan system and feudal ethics, thus completing the most profound exposure and criticism of feudal ethics on the nature of eating people.
