He succeeded his father Liu Sheng because he was the eldest son. He only left eunuchs in power in his court and mandated castration for anyone who he wanted to work for his court because he believed people with children could not be completely loyal. When Liu Chang became Emperor he was only a "mere youth".
Reign
Liu became Emperor when he was sixteen years old. Historical records report that Liu Chang spent so much time with his harem that he abandoned government affairs. His most favorite concubine was one young Persian girl he called Mèi Zhū. The "History of Five dynasties and Ten Kingdoms" described the Persian woman as having copper colored skin and large eyes. It was told that she loved pearls so Liu Chang ordered fishermen to dive to find thousands of pearls for his Persian lover Mei Zhu. Many of the fishermen died. He gave her a pearl dudou, pearl crowns, pearl blouses, and pearl skirts. He also used pearls and silver to renovate his palaces. The historical text Spring and Autumn Annals of the Ten Kingdoms recorded that Liu Chang indulged in sex games. He had alchemists create aphrodisiacs to induce sexual desire as pregame warmup. One of his games was called "Naked in Twos" in which he paired young men with palace women, made them strip naked and have sex together while he and his Persian lover were carried around to watch them. Liu and Mei Zhu then decided whether the man or woman "won". If the man "defeated" the woman, both were rewarded, but if the woman won and defeated the man, Liu had the man castrated. Liu had sex all day and night and his body was physically unable to bear it, so he started to learn Jianyang techniques to invigorate his "yang" male energy. The Historical Records of the Five Dynasties says that Liu Chang spent all his time in the harem, and that he never came out to handle governance work, leaving it to Kong Chengshu and the eunuchs to take over government business. The naked orgies he had were similar to those his uncle Liu Bin had. Graphic descriptions of what the Persian woman and Liu Chang did together were recorded in written by. The gives the same account as the Qingyilu. They mention a hall installed in his palace called "Hou chuang jian" where he indulged himself with her. The fact that Liu Chang's harem had Persian girls is seen as evidence for the existence of a Persian community in southern China during this time. There was a thriving Persian community in Guangzhou during the 10th-12th centuries. The Persians in Guangzhou were called either Bosi 波斯 or Pusaman meaning "Muslim" in Persian. Liu Chang also employed women shamans. He is also known to have held the "Red Cloud Banquet", a festival for the litchi fruit. During the same era, another young Chinese EmperorWang Zongyan who was only 20 years old when he ascended the throne, had a Persian woman as his concubine, Li Shunxian. He was the last Emperor of Southern Han as his kingdom was defeated and taken over by the Song dynasty in 972. He reigned for a total of 14 years.
