Lu Xun's pen name was Lu Xun because he used a character to replace his original name, Zhou Shu Ren, and added a pen name. His pen name "Lu Xun" came from the pen name "Lu Xun's novels" that he used in his novels. This was because he often used first-person narrations when writing, and his writing style also had some irony and criticism, so he was called "Lu Xun". His literary works had a profound impact on the development of modern Chinese literature and was hailed as one of the founders of modern Chinese literature.
