One of the most outstanding strategists during the Three Kingdoms period was Zhuge Liang. He was an important advisor to Liu Bei, the founding emperor of Shu Han, and was known as "Mr. Wolong". Zhuge Liang not only understood politics and military, but he also had in-depth research in the fields of culture, philosophy, and so on. His famous sayings such as "divide the world into three parts" and "do your best until you die" were still praised by people today. Other strategists of the Three Kingdoms period, such as Cao Cao's Xun You, Sima Yi's Jia Xu, and Sun Quan's Zhou Yu, also performed well and made important contributions to the establishment and development of Dongwu, Shuhan, and Wei.
