Emperor Xiaowu died naturally in 464 and was succeeded by his son, who became Emperor Qianfei. Emperor Qianfei proved to be similar to his father, engaging in both kin-slaughter and incest. In a scandalous move, because his sister complained about how it was unfair that men were allowed 10,000 concubines, he gave her 30 handsome young men as lovers. His uncle Liu Yu, the Prince of Xiangdong, whom he called the "Prince of Pigs" for his obesity, eventually assassinated him and became Emperor Ming.
