Cao Cao (played by Bao Guoan) wrote the word "live" on the gate, and Yang Xiu asked people to modify the gate. Seeing that Yang Xiu understood his intentions deeply, Cao Cao praised Yang Xiu for being astute. Zhang Song, the envoy of Xichuan, came to visit Cao Cao, and Yang Xiujin remonstrated that he could use this to win Xichuan's hearts. When Cao Cao saw Zhang Song, he was unhappy and left without chatting a few words. Yang Xiu saw that Zhang Song was extraordinary, and during the conversation, he showed Zhang Song the art of war written by Cao Cao in his hand. Zhang Song laughed and said that even children in Sichuan could recite it. After Yang Xiu told Cao Cao about his conversation with Zhang Song, Cao Cao burned his handwriting. Cao Cao demonstrated to Zhang Song on the teaching ground. Unexpectedly, Zhang Song told the battles of Cao Cao's defeat one by one, and Cao Cao wanted to kill Zhang Song when he was angry. Yang Xiu and Xun Yu tried to persuade Zhang Song, but Zhang Song was beaten out with sticks. When Zhuge Liang (played by Tang Guoqiang) learned of Zhang Song's encounter, he sent Zhao Yun and Guan Yu (played by Lu Shuming) to meet him. At the moment Zhang Song is worried that Xichuan will not be able to meet the blessing of the Lord of the Ming Dynasty. Zhang Song is invited to come and receives warm hospitality from Liu Bei (played by Sun Yanjun). During the conversation, he is very moved. When Zhang Song left, he was moved by Liu Bei's benevolence again, and expressed his concern for Xichuan, and dedicated the map of Xichuan to Liu Bei to help Liu Bei establish a foundation in Xichuan. Zhang Song later persuaded his master to welcome Liu Bei to protect the peace of Xichuan. Zhuge Liang, Guan Yu and others guarded Jingzhou, while Liu Bei and Pang Tong led their troops to Xichuan.
