Empress Lü Zhi
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.
