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).
Consort Qi
Qi was born in Dingtao, Shandong. She bore Emperor Gaozu a son Liu Ruyi, who was later installed as Prince of Zhao. Gaozu felt that the crown prince Liu Ying (his second son) was an unsuitable heir to his throne. He tried several times, fruitlessly, to replace Liu Ying with Liu Ruyi, as his desire was objected to by Liu Ying's mother Empress Lü Zhi. Because of this, Lü Zhi hated Qi deeply. Nevertheless, Gaozu ordered Liu Ruyi to proceed to his principality of Zhao (capital in present-day Handan, Hebei) on his deathbed. Qi did not accompany Liu Ruyi.
