The Duke Of Mount Deer is a chivalrous novel written by Jin Yong, a modern writer in China. This novel tells the story of Wei Xiaobao, who grew up in a brothel in Yangzhou. Without any martial arts, he wandered among the major gangs in the Jianghu and went on an expedition to Yunnan and Russia on the orders of the emperor's courtiers. He created an image of a nobody completely different from the traditional chivalrous man, and used this image to satirize some hypocritical hypocrites and pedantic and stubborn ideas, showing the idea of national unity.
