She is Yan Zhaowang's mother. History books call her "Queen Yan Yi". Before she became the Empress Dowager, according to the custom in the Spring and Autumn Period and the Warring States Period, she should be called Meng Ying, which means the eldest daughter who won. Meng Ying was brought up by the elder sister of the King of Qin, Ying Fu, with a cheerful and generous personality. As a friend of Mi Yue, she entered the State of Qin and helped Mi Yue's younger brother Wei Ran when he was in danger. She is another mirror of Mi Yue. Although she was a princess, she had to be a political victim of her father, married Yan, and her husband was exiled after his death. She also supported her son's accession to the throne and worked hard for his country. But the biggest difference between Meng Bi and Mi Yue is that Meng Bi loves Su Qin deeply, but prefers to be the shadow behind men, while Mi Yue prefers to stand at the front desk and fight against the world.
