As a general in the late Han Dynasty, Guan Yu was generally not well-respected during his lifetime, but he stood out among the heroes for thousands of years and became a god who "protected the country and the people" in the land of China. "There are Confucius temples in counties and related temples in every village", which shows that Guan Gong's belief has penetrated deeply into the grassroots and has been implanted in the people's hearts. A couplet like the Guan Temple in the Qing Dynasty can quite summarize Guan Yu's historical status and great influence in traditional Chinese society. Guan Gong's belief is of great significance for examining the cultural psychology of the Chinese nation. In this process of "creating gods", various literary styles such as legends, notes, ordinary stories, operas, and novels interact with folk customs, religions, ethics, philosophy, and institutions. The image of Guan Yu continues to develop and change, and it has now passed 1,800 years, and it seems to have become an unsolvable mystery in Chinese history and culture.
