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).
Jiandi
Jiandi (), also with variants 簡易/简易 and 簡逷/简逷, is an important figure in Chinese history and in Chinese mythology. She was the second wife of Emperor Ku, who was a descendent of the Yellow Emperor. Jiandi was the mother of Qi, the predynastic founder of the Shang dynasty (note that this is a different Qi than the Qi Ji born to Di Ku's first wife Jiang Yuan). Her pregnancy miraculously occurred following her swallowing or holding in her bosom the egg of a bird. Jiandi was said to be of the Yousong clan. Jiandi is mentioned in various sources, including the poems "Eulogy of Shang", in the "Shijing", and the "Heavenly Questions" in the "Chuci".
