King Zhaoxiang of Qin
In 306 BC, the young King Zhaoxiang ascended to the throne, with his mother Queen Dowager Xuan serving as regent. Knowing Qin could not focus on eradicating Yiqu when it had the hostile eastern states to deal with, and her son's rule was still shaky due to numerous rival princes keen to capture the throne, Queen Dowager Xuan decided to use an approach of pretended conciliation. She invited the king of Yiqu to live long-term in the Ganquan Palace, and consummated a seductive liaison that produced two sons with him. This completely removed the Yiqu King's hostility towards Qin, as the beguiled king had lost all cautiousness around the Queen Dowager. At the same time, King Zhaoxiang was aggressively acting to weaken rival warring states in the east and south, and Queen Dowager Xuan was secretly planning with her son the eventual annihilation of Yiqu.
Queen Dong
In 1623, Dong was born in a Jinjiang family with scholar-official, and her father was Dong Yangxian, a politician of Southern Ming. In 1642, Dong married Koxinga and gave birth to Zheng Jing. In 1649, Koxinga became Prince of Yanping (); as the result, Dong became his princess consort. In 1662, Koxinga defeated Frederick Coyett and his army in the Siege of Fort Zeelandia, and Kingdom of Tungning was later built. After Koxinga died, Dong's son Zheng Jing won the succession to the throne of Tungning by defeating Zheng Xi in a civil war and Zheng Tai in a political struggle. In 1681, Dong died in Tainan, Taiwan.
