It is said that Zhuge Liang lived in seclusion in Shan Ye and worked in the fields. His talk with the villagers reflected his broad mind of caring for the world. After Liu Bei knew it, he went to visit. There was no good food and meal in a poor life. His wife fried the remaining rice crust for Liu Bei to enjoy. Liu Bei liked it very much. Zhuge Liang told him that it was called Wolong rice crust, which was the origin of Wolong rice crust.
