These four figures are Di Xin, one of the four beauties, Zhao and Mu, one of the eight sages, and Mulan, whose father joined the army. These characters are all characters in novels and do not exist. For example, in The Story of Diusim, in The Romance of Three Kingdoms, Wang Yun used the story of Diusim's beauty to give the story of Diusim to Dong Zhuo first, and then to Lu Bu. In this way, the dispute between father and son was provoked, and finally Lu Bu won the crown and killed Dong Zhuo, the adoptive father.

However, there are no strange girls in history. Historically, Lu Bu had an affair with one of Dong Zhuo's concubines. Maybe Luo Guanzhong made it up based on this princess. The second Zhao, the Eight Saints, holds a golden hoop. It is said that it was given by Emperor Taizong, who was in charge of injustice.

According to legend, Zhao, the fourth son, was given this golden cudgel specially after he ascended the throne. The image of the Eight Immortals King generally appears in similar TV dramas or novels, which is specially used to protect the loyalty of Yang Jia and Bao Zheng. According to textual research, his prototype may come from his eighth brother and his fourth son Zhao.

Mu is also, there is no such person in history, but everyone's beautiful imagination of Yang's family. However, Mulan is controversial. Some people say that Mulan does exist, but she was brought into the harem by the emperor after her triumphant return. It is also said that Mulan does not exist, which is just a figure invented by the author of Mulan Ci. But in any case, whether these four words exist or not, they all place a good wish on everyone.
