The Story of Romance of the Three Kingdoms.

In AD207, on the recommendation of Sima Hui and Xu Shu, Liu Bei paid three visits to the thatched cottage of Zhuge Liang asking for his assistance. From the Longzhong area, he introduced his detailed plan for reunifying the whole nation. This both enlightened and pleased Liu Bei and his initiatives were subsequently called the 'Longzhong Dialogue'. From that point on, he began to assist Liu Bei in realizing his political goal to reestablish the Han Dynasty (206 BC - 220 AD).
