King Zhaoxiang of Qin
Because King Zhaoxiang had not yet legally come of age (traditionally at the age of 20), his mother, who was now known as Queen Dowager Xuan, became the regent. She was supported by her brothers, Wei Ran and Mi Rong (羋戎), as well as two other sons, Prince Yi (公子悝) and Prince Fu (公子巿), the four of them collectively known as the "Four Nobles" (四貴).
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.
