There is an old saying that goes, "It is better to learn from Taoyuan, where three people are sworn brothers, than to learn from Wagang, which is a furnace of incense."

The old saying "It is better to learn from Taoyuan than to learn from Wagang to make incense" means:

Three brothers from Taoyuan are sworn brothers, Liu, Guan and Zhang kowtow to each other. On earth he is the same as his brothers, and is respected by future generations. A burner of incense in Wagang. During the Sui and Tang Dynasties, the forty-six friends Jiajialou of Wagang kowtowed to the ground. Later, for their own interests, they not only broke up, but even killed each other. It's not even worthy of sighing.

This sentence comes from "The Romance of the Three Kingdoms". "The Romance of the Three Kingdoms" describes the historical events of nearly a hundred years from the end of the Eastern Han Dynasty to the early years of the Western Jin Dynasty. The whole book reflects the political and military struggles of the Three Kingdoms era, reflects the penetration and transformation of various social contradictions in the Three Kingdoms era, summarizes the great historical changes of this era, and creates a group of powerful heroes. In terms of grasping the history of the Three Kingdoms, the author showed an obvious tendency to support Liu and oppose Cao. He took the Liu Bei Group as the center of the description, praised the main figures of the Liu Bei Group, and tried his best to expose and criticize Cao Cao. Today we should have a dialectical understanding of the author's tendency to support Liu and oppose Cao. Respecting Liu and rebelling against Cao was the main trend in folklore, which during Luo Guanzhong's time implied the people's hope for the rejuvenation of the Han nation.
