Zhuge Liang (181 AD-234 AD), with the courtesy name Kongming, was born in Yangdu of Langya ( present-day Yinan, Shandong Province), and later settled in Longzhong, west of Xiangyang, Hubei Province. He led a hermit's life and associated with notable people, associating himself to famous figures such as Guan Zhong and Yue Yi. With a reputation for wisdom spreading far and wide, he was called the“Crouching Dragon”. Liu Bei had to make three humble visits to his thatched cottage before he was willing to see him. Zhuge Liang analyzed the situation in the country in detail for Liu Bei, and advised Liu Bei to occupy Jingzhou and Yizhou Prefectures and ally himself with Sun Quan against Cao Cao. Liu Bei was so excited that he invited Zhuge Liang to assist him. This was the origin of the story about“three humble visits to the thatched cottage”.
According to Zhuge Liang's strategy, Liu Bei successfully established the Shu-Han regime, forming a tripartite confrontation with Sun Quan and Cao Cao. In the first year of Zhangwu (221 AD), Liu Bei proclaimed himself emperor and appointed Zhuge Liang as chancellor. After the failure of annexing Wu, Liu Bei entrusted Zhuge Liang the whole state in Yongan. After Liu Chan ascended to the throne, Zhuge Liang was granted the title of Marquis of Wuxiang and the governor of Yizhou. He was diligent and cautious, and handled big and small political affairs personally with strict and impartial grounds for rewards and punishments. He Allied with Wu and improved relations with all ethnic groups in Southwest China. Zhuge Liang implemented the policy of opening up the wasteland and strengthened the state's combat readiness. He made five northern expeditions to the central plains, but failed to achieve the goal of reviving the Han Dynasty. Eventually, due to overwork, Zhuge Liang died in Wuzhangyuan ( present-day Qishan, Baoji City, Shaanxi Province) in the 12th year of Jianxing (234 AD) at the age of 54.
