Empress Lü Zhi
Later, through the efforts of Consort Bo, Queen Zirang got pregnant and gave birth to a son prematurely, and asked Dou Yifang to bring up her son before she dies. Years later, Dou Yifang also gave birth to Princess Guantao and Prince Liu Qi. Dou Yifang treated the three children fairly, as a mother do to their children. However, Zirang's child was murdered by Zisu, a maid of Dai whom Consort Bo used to distract Liu Heng from Yifang albeit unsuccessful (Zisu is indebted to Yifang so she tries to pay the debt by removing the obstacle to the crown for Yifang's son, Liu Qi). Everyone thought that it was Dou Yifang who murdered Zirang's child, and Consort Bo hated her to death. Dou Yifang used this unfortunate incident as a balance between Empress Lü Zhi and Dai, and helped Liu Heng to save time to plot insurrection.
