Cao Cao sent his men to ride fast horses to catch up, and finally caught up with Liu Bei near Osaka in Dangyang. At this time, the situation is very critical. Liu Bei left his wife and children behind and fled south with dozens of men, including Zhang Fei, Zhuge Liang and Zhao Yun. At this time, zhaoyun instead entered the forces of Cao Jun in the north. When someone saw Zhao Yun going north, they told Liu Bei that Zhao Yun must have gone north to take refuge in Cao Cao. Hearing this, Liu Bei threw the halberd at the accuser and said, "Zilong won't leave me."
Zhao killed more than 50 Cao Cao generals, stained his shirt with blood, embraced Liu Bei's youngest son Dou, and risked his life to return to Liu Bei.
