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).
Emperor Ming of Southern Qi
Xiao Luan was born in 452. His mother's name is lost to history, and his father was Xiao Daosheng (蕭道生), a mid-low-level official during Liu Song. Xiao Daosheng died early, and Xiao Luan was raised by Xiao Daosheng's younger brother Xiao Daocheng, a Liu Song general. He had two brothers, Xiao Feng (蕭鳳), who was older, and Xiao Mian (蕭緬), who was younger. Xiao Daocheng was said to have loved Xiao Luan greatly, even more so than his own sons. In 472, at the age of 20, Xiao Luan was made a county magistrate, and during the next few years, as his uncle's powers increased, he was promoted through a number of positions, becoming a general in 478. When Xiao Daocheng took over the throne from Emperor Shun of Liu Song in 479, ending Liu Song and establishing Southern Qi, he created Xiao Luan the Marquess of Xichang.
