Why is Zhou Shuren's pen name "Lu Xun"?

There have always been two explanations for the pseudonym "Lu Xun": one thinks that the word "Lu" is the surname of Mr. Lu Xun's mother, and "Luzhen" often mentioned in novels is his mother's hometown; "Xun" is his nickname, so the word "Brother Xun" also appears in his novels. Another explanation is that Mr. Xu Shoushang, a close friend of Mr. Wang, said that he personally asked Mr. Lu Xun, and Mr. Wang smiled and said, "Take the meaning of being stupid and quick." This is Mr. Self-mockery. These two statements are both literal explanations, which are also in line with Lu Xun's life, and both make sense.

Recently, a third explanation has been discovered. People think that the word "Xun" means wolf in ancient times. See Er Ya Shi Beast for the source: "The wolf is extremely powerful and quick." According to this annotation, "Lu Xun" refers to the son of a brave and powerful wolf. Historian Hou Wailu holds this view. He said that Lu Xun was a rebel in feudal society, and his masterpiece Diary of a Madman attacked the "cannibalism" system in feudal society. He used these two words as his name, which clearly expressed his will to pretend to be a "wolf" and completely break away from the feudal social system.

It is said that Hou Wailu's explanation was mentioned by Lu Xun's wife, Xu Guangping, and Xu Guangping repeatedly praised and agreed.
