Bai Lingyun's role prototype is Mrs. Bai. Mrs. Bai, surnamed Bai, whose name is not recorded in the history books, was a favorite of Sima Yi, the minister of Cao Wei in the Three Kingdoms period, and the mother of Sima Lun, the king of Zhao who proclaimed himself emperor during the Eight Kings Rebellion.
In his later years, Sima Yi loved Mrs. Bai and alienated his wife Zhang Chunhua, so Zhang Chunhua seldom saw Sima Yi. Once Sima Yi was sick and Zhang Chunhua went to visit the sick. Sima Yi said to Zhang Chunhua, Why bother you, ugly old woman! ;
Zhang Chunhua was very angry and declared that he would go on a hunger strike, and Zhang Chunhua's sons Sima Shi and Si Mazhao would also go on a hunger strike with his mother. Sima Yi hurriedly apologized to Zhang Chunhua. Zhang Chunhua was very happy and stopped the hunger strike. Afterwards, Sima Yi secretly said to Mrs. Bai: The old lady is dead and there is nothing to be ashamed of. I'm worried about my good sons! ;
There is no record of Mrs. Bai's name in history. The so-called name is the fictional name of Li, the author of Sima Yi's Eat the Three Kingdoms. There is no source of information, so it is not credible. In the Romance of the New Three Kingdoms, the undercover agent sent by Cao Pi to spy on Sima Yi was based on the White Snake.
