고황후
Against all odds, with the trust and concern from Liu Heng, she goes through difficulties and triumphs over plots and schemes. Sensing the unrest following the assumed death of Liu Ying, Liu Heng wishes to raise arms and troops but was troubled about how to do so without alarming Lü Zhi. Yifang helps her husband on the matters of military training in secret by suggesting him to order for the building of the Royal Mausoleum to achieve immortality, which in turn tricks Empress Lü Zhi into believing that she has led Liu Heng stray, therefore rendering him as harmless. This led the ministers of Dai to think that she was a bad woman, and requested Liu Heng to sentence her to death. Yifang concedes with the negative impressions she made to the ministers and carried on to let them flourish to make her plans to deceive Lü Zhi realistic. Only Liu Heng understands her and respects her for her sacrifices.
