What is the significance of Zhao Zilong Savior in divination?

In the 13th year of Jian 'an (AD 208), Liu Bei was defeated and fled south to Jiangling. Cao Cao sent people to ride fast horses and finally caught up with Liu Bei near Changsakan in Dangyang. At this time, the situation was critical. Liu Bei left his wife and children and fled south with dozens of men, including Zhang Fei, Zhuge Liang and Zhao Yun, while Zhao Yun went north to join Cao Jun's army. Someone saw Zhao Yun going north and 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." . Sure enough, Zhao Yun hugged Liu Bei's youngest son, protected Liu Bei's wife, Mrs. Gan, and returned to Liu Bei safely. Zhao Zilong's hero and savior means that he saved young master Liu Chan in Changbanpo.
