Before the Chibi War, Zhuge Liang decided that Cao Cao was defeated and walked away from Huarong Road. He watched the celestial phenomena at night. Cao Cao died improperly. First, considering the feelings of Cao Cao and Guan Yu, he sent Guan Yunchang to guard Huarong Road, leaving a personal feeling for Guan Yu. Second, if the state of Wei is destroyed at this time, it will make the State of Wu fully attack Shu, and make Shu in dire straits. As expected, Cao Cao retreated from Wulin to Huarong Road and laughed three times on the way. Zhuge Liang and Zhou Yu were not wise enough to ambush in dangerous places.

Cao Cao laughed and worshipped Zhao Yun and Zhang He as enemies, so he could get away. Two laughed out of Zhang Yide, two generals, Zhang Liao and Huang Xu, boycotted Zhang Fei and made Cao Cao escape again. San Xiao is serious, laughing at Guan Yunchang. He is on the narrow road of Huarong Road, which is dangerous, while one person guards it. In addition, Cao Jun has been unable to fight again at this time. Helpless, Cao Cao had to listen to the adviser and let Guan Yu go himself. Guan Yu thanked the old days and let Cao Cao go back to Jiangling.
