Gulongzhong is the place where Zhuge Liang lived in seclusion with his uncle in his youth (17-27 years old). Zhuge Liang lived in seclusion here for 10 years. Liu Bei visited the thatched cottage and invited Zhuge Liang to come out of the mountain. From the winter of 207 to the spring of 208, Liu Bei, who was stationed in Xinye at that time, visited Zhuge Liang in Longzhong three times at the suggestion of Xu Shu, but it was not until he met the dignitaries for the third time. Zhuge Liang analyzed the world situation for Liu Bei, and put forward the strategic idea of taking Jingzhou as his home, Yizhou as his foothold and the Central Plains. It can be said that Longzhong is the source of the culture of the Three Kingdoms.
