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).
Princess Taiping
Princess Taiping (, lit. "Princess of Great Peace", personal name unknown, possibly Li Lingyue (李令月)) (died 2 August 713) was a princess of the Chinese dynasty Tang Dynasty and her mother Wu Zetian's Zhou Dynasty. She was the youngest daughter of Wu Zetian and Emperor Gaozong and was powerful during the reigns of her mother and her elder brothers Emperor Zhongzong and Emperor Ruizong (both of whom reigned twice), particularly during Emperor Ruizong's second reign.
