Lu Xun was a Chinese writer, poet, literary critic, and essayist. He is a central figure in the New Culture Movement and is revered as one of the greatest Chinese writers of the 20th century. Born Zhou Shuren, he adopted the pseudonym Lu Xun in 1918 upon publishing his first major work, "Diary of a Madman." His short stories, such as "The True Story of Ah Q," are known for their social realism, satire, and penetrating critique of traditional Chinese culture and psychology. He graduated in medicine from Sendai Imperial University in Japan but returned to China in 1909 to pursue teaching and writing. Lu Xun served in various governmental and educational positions, but it was his literary output that cemented his legacy. He passed away in Shanghai on September 18, 1936. His work continues to be studied and admired for its literary depth and historical significance.
