Lu Xun (September 25, 1881-October 19, 1936) started using the pen name "Lu Xun" around 1918. This pen name came from his original name, Zhou Shuren, and the pen name "Lu Xun" was later chosen by him to better express his thoughts and style in literature. In his later years, some of his works, such as A Madman's Diary and The True Story of Ah Q, also used the pen name "Lu Xun".
