Xu Shu, whose character is straight, is a strategist with a unique charm. He is from Yingchuan, Yuzhou. As an important strategist under Liu Bei in the late Eastern Han Dynasty, his wisdom and strategy made great contributions to the development of Shu Han. However, Xu Shu eventually chose to leave Liu Bei and throw himself into Cao Cao's arms, which undoubtedly added more uncertainty and drama to the historical course of the Three Kingdoms.
After Xu Shu entered Jingzhou, he got acquainted with Sima Hui and admired his name, so he worshipped him as a teacher and became a brother with Pang Tong and Zhuge Liang. After Xu Shu and Zhuge Liang met, they deeply felt each other's charm, and during the conversation, they frequently exchanged and gradually became close friends. They often talked about world affairs together, shared ways of governing the country and using troops, learned from each other and tempered each other, and their friendship gradually warmed up.
Liu Bei came to Jingzhou to visit the famous soldiers, showing an ambitious but humble attitude. In his observations again and again, Xu Shu determined that Liu Bei was a master worthy of service. Sima Hui also tried his best to persuade Xu Shu to defect to Liu Bei, so Xu Shu defected to Liu Bei without hesitation. Under Liu Bei, Xu Shu showed outstanding military talent and was relied on by Liu Bei. Not only is he full of wealth, but he is also able to choose people who are really helpful to the lord. Xu Shu strongly recommended Zhuge Liang to Liu Bei, and Liu Bei already had the intention of recruiting Zhuge Liang in his heart, so he went to visit without hesitation, and achieved the good story of "three visits to the thatched house". It can be said that Xu Shu is the most valuable strategist in Liu Bei's army. Because he is not only talented, but also able to recommend more talents to Liu Bei. If Liu Bei didn't have Xu Shu's help, he might not have been able to get in touch with these celebrities who were temporarily living here to escape the war. It is precisely because of Xu Shu's rich interpersonal network that Liu Bei was able to come into contact with these talents. Liu Bei was also able to get his most important advisor Zhuge Liang by chance, laying a solid foundation for the rivers and mountains of Shu.
