What is literature? Literature is human studies. Literature is a reflection of people's daily life and a representation of the relationship between human beings and nature. Literature can not only reveal the essence of life, but also reflect people's emotions. Without literature, human life would be boring. Therefore, great writers are engineers of the human soul. Lu Xun was a great litterateur, thinker, and literary giant of the 20th century. His influence and contribution to modern Chinese culture were enormous. Lu Xun wrote a large number of essays throughout his life and created a series of short and medium-sized novels such as "Diary of a Madman" and "The True Story of Ah Q." He revealed the "cannibalistic" nature of traditional society and various hidden diseases of modern society.
