The explanation in the textbook is that Lu Xun's mother's surname is Lu, and Lu Xun named Lu Xun in memory of her mother. In fact, this only explains the origin of surname in Lu Xun's pen name.
For the origin of another word Xun, this is very crucial. Xun is his posthumous title, so the word Brother Xun appears in his novels. Another explanation is said by Xu Shoushang, a close friend of Lu Xun. He asked Mr. Lu Xun himself, and Mr. Lu smiled, meaning stupid and quick.
The second statement is easy to convince. Xun has the meaning of fast and powerful. The reason why Lu Xun gave himself a pen name in this way can also infer Lu Xun's inner thoughts in his time, so as to see Lu Xun's character.
Role name background
Lu Xun lived in an era when the conflict between old and new ideas was the fiercest in China society, especially in his understanding of new culture. Scholars such as Lin Yutang and Liang Shiqiu had a contest with Lu Xun in the literary world at that time. It is precisely because of this competitive environment that Lu Xun urged himself to be quick. He needed to discuss his views quickly and forcefully, and quickly and forcefully counter the wrong views at that time.
At that time, Lu Xun did not have a high and complete academic background, nor did he study literature, history and philosophy, but he became a master of literary thought. Relying on diligence and hard work, he doesn't think he has any genius, but spends all his time drinking coffee, chatting with others, reading and writing.
