In 453, he was killed by Prince Shao, and the third son took the opportunity to lead the army to seize the position, namely Emperor Xiaowu of Song Dynasty. He was a dissolute man, raped his niece, had two imperial clan wars, and finally slaughtered Guangling City. At that time, the folk song said, "Looking at Jiankang City from a distance, Xiaojiang went upstream, seeing his son kill his father before, and seeing his brother kill his brother later", which foreshadowed this history. His son abolished the emperor before, killed the imperial clan after the establishment, and was later killed by Liu Mi, the king of eastern Hunan, by Emperor Song Ming. But he also killed the imperial clan, so that all the descendants of Emperor Xiaowu of Song Dynasty died.

After his son Song abolished the emperor, the political situation made waves, and there were many rebellions. General Xiao Daocheng gradually mastered the military power. After Fei Di's death, he established the Song Dynasty and monopolized the state affairs. After destroying his political enemy Yuan Zhen, he usurped the throne in 478 and established Qi State in the Southern Dynasties, known as Qi Emperor in history, and died in the Southern Dynasties and the Song Dynasty.
