There are many theories about the origin of farmers' grilled fish, among which Zhuge Liangyi, who originated in the Three Kingdoms, said that Zhuge Liang, who lived in seclusion in Langya County at that time, loved grilled fish, which was different from ordinary grilled fish in materials and practices. When Zhuge Liang prepares a family dinner, he often invites several friends to share delicious grilled fish. Later, Zhuge Liang left Longzhong to help Liu Bei conquer the world; After Liu Bei proclaimed himself emperor in Chengdu, Zhuge Liang recommended him to the palace. This kind of grilled fish was not only eaten by Zhuge Liang, but also enjoyed by Liu Bei, Guan Yu and others, and became an essential food at the royal banquet. In Battle of Red Cliffs, Lu Su went to Liu Bei to think about Wu Kang Cao, and Liu Bei entertained him with this grilled fish. Lu Su had never eaten such a unique and delicious grilled fish, so he asked Liu Bei what the name was. Liu Bei laughed and said that this dish was created by Mr. Zhuge and has no name yet. After thinking about it, Lu Su said that since Mr. Zhuge created this delicious food, it was called "Zhuge grilled fish". Zhuge Liang was very uncomfortable when he heard this. Explained: When I was a farmer in Longzhong, Shan Ye, I absorbed the villagers' grilled fish skills and summarized the cooking methods. It is more appropriate to call it "farmer grilled fish". So "Zhuge grilled fish" is also called "farmer grilled fish".
