Introduction to Lu Xun, the "Backbone of a Great Country"

Lu Xun used his pen as his sword throughout his life and took it as his mission to enlighten the people's wisdom. He never ignored the confusion and ignorance of the people in crisis, just as he said in " "The Scream" said in the preface that "it started shouting loudly and startled a few people who were more sober." At the same time, he also clearly realized that the root cause of the country's decline a hundred years ago did not lie with the people. On the contrary, in that turbulent era, a large number of confident people emerged who faced difficulties, were not afraid of hardships, and had confidence. The Chinese people, it is they who shine China's future and forge China's bones.

Lu Xun and Confucius, two thinkers who were both in the midst of great turmoil and transformation, explored the underlying logic of social operation in different ways. Confucius advocated the concept of "benevolence", focused on the maintenance of order, and proposed a path from difference to harmony; and two thousand years later, Lu Xun re-saw the value of "people" and advocated "respecting individuality and promoting spirit", and will give full play to individuality regarded as the "highest morality".
