Liu Cheng

Liu Sheng (; 920–958), born Liu Hongxi (劉弘熙), possibly nicknamed Jun (雋), also known by his temple name as the Emperor Zhongzong of (Southern) Han ((南)漢中宗), was the third emperor of the Southern Han dynasty of China during the Five Dynasties and Ten Kingdoms period. He succeeded his brother, Liu Bin (Emperor Shang), whom he had ordered assassinated to allow himself to take the throne.

Background Liu Hongxi was born in 920, as the fourth son of Liu Yan, who was then already the emperor of Southern Han (as Emperor Gaozu)—and therefore, was likely born at Southern Han's capital Xingwang (興王, in modern Guangzhou, Guangdong). —died early, his third older brother Liu Hongdu the Prince of Qin became the expectant heir as the oldest surviving son of Liu Yan. In 945, he killed another brother, Liu Hongya (劉弘雅) the Prince of Shao. He also put four of Chen's coconspirators to death, and forced the high-level official Wang Lin (王翷), whom he believed had supported Liu Hongchang's succession, to commit suicide. It was said that after these deaths, the entire state was in fear. In 946, he also put Chen and another official who warned Chen, Deng Shen (鄧伸), to death.

In 947, Liu Sheng, concerned that his brothers would contend for the throne with his sons, executed many, possibly all, of his remaining brothers—Liu Hongbi, Liu Hongdao (劉弘道) the Prince of Gui, Liu Hongyi (劉弘益) the Prince of Ding, Liu Hongji (劉弘濟) the Prince of Bian, Liu Hongjiǎn (劉弘簡) the Prince of Tong, Liu Hongjiàn (劉弘建) the Prince of Yi, Liu Hongwei (劉弘偉) the Prince of En, and Liu Hongzhao (劉弘照) the Prince of Yi (different character than Liu Hongjiàn). He took their daughters into his palace to be part of concubinage. He also built palaces with a total of a thousand rooms and adorned it with jewels. He further created a number of inhumane punishments, calling it, "the Living Hell." (It was said that Liu Sheng's killing of his brothers was encouraged by and planned in conjunction with his trusted eunuch Lin Yanyu.)

In 948, Liu Sheng commissioned the official Zhong Yunzhang (鍾允章) on a diplomatic mission to Southern Han's northern neighbor Chu, seeking a marital alliance with Chu's prince Ma Xiguang. (Liu Yan's wife—likely not Liu Sheng's mother—was a sister of Ma Xiguang's.) Ma Xiguang refused, angering Liu Sheng, and Liu Sheng, after Zhong advised him that the Chu state was embroiled in fraternal struggles for power among Ma Xiguang's brothers, decided to attack Chu. Later in the year, he sent the general Wu Huai'en (吳懷恩) to attack Chu. Wu defeated the Chu general Xu Zhixin (徐知新), and seized He (賀州, in modern Hezhou, Guangxi) and Zhao (昭州, in modern Guilin, Guangxi) Prefectures for Southern Han.

By 951, Chu, weakened by the internecine struggles between the Ma brothers, had fallen to its northeastern neighbor Southern Tang. Ma Yin's son Ma Xiyin, however, was still in control of Chu's Jingjiang Circuit (靜江, headquartered in modern Guilin) as its deputy military governor. Liu Sheng commissioned Wu Huai'en with an army and sent Wu to the borders with Jingjiang, planning to conquer it. Meanwhile, another Ma brother, Ma Xi'e, who had briefly seized the Chu throne before being deposed, was still had some followers, and he sent the general Peng Yanhui (彭彥暉) to Jinjiang's capital Gui Prefecture (桂州) to take over actual command, drawing Ma Xiyin's ire, so Ma Xiyin secretly summoned the general Xu Keqiong to Gui Prefecture, and Xu was able to expel Peng from the city. Wu took this opportunity to capture Chu's Meng Prefecture (蒙州, in modern Wuzhou, Guangxi) and send his soldiers to pillage the rest of Jingjiang territory, causing Ma Xiyin and Xu to be terrified, but they had no strategy to defeat Wu. Liu then wrote a letter to Ma Xiyin, claiming that his intent was to aid Ma Xiyin:

Ma Xiyin considered surrendering to Southern Han, but could not decide immediately. When Wu quickly reached Gui Prefecture, Ma Xiyin and Xu instead abandoned it and fled to Quan Prefecture (全州, in modern Guilin). Wu was thereafter able to take over not only Gui but the rest of Jingjiang, allowing Southern Han to possess all of the Lingnan region. Later in the year, Liu further sent the generals Pan Chongche (潘崇徹) and Xie Guan (謝貫) to capture Chen Prefecture (郴州, in modern Chenzhou, Hunan) from Southern Tang.

In 954, Liu Sheng commissioned one of his remaining brothers, Liu Hongmiao (劉弘邈) the Prince of Gao to be the military governor of Xiongwu Circuit (雄武, headquartered in modern Nanning, Guangxi). As both Liu Hongbi and Liu Hongze had previously served at that post before their deaths, Liu Hongmiao became apprehensive and tried to decline the post, requesting that he remain as an imperial guard officer, but Liu Sheng refused the offer. When Liu Hongmiao reached Xiongwu, he tried to ward of suspicion by entrusting the governance to others, instead spending his days drinking and praying to the gods and the spirits. There were nevertheless accusations of treason made against him, and Liu Sheng sent Lin Yanyu to Xiongwu to force him to commit suicide.

In 956, Lin died, causing the people of the realm to celebrate. Before Lin's death, he recommended another eunuch, Gong Chengshu, to succeed him, and Liu Sheng commissioned Gong to oversee the eunuchs.

In 957, Liu Sheng, hearing that Later Zhou, which controlled the Central Plains, was repeatedly scoring victories in its war against Southern Tang, became worried that if Later Zhou conquered Southern Tang, Southern Han would become its target. He tried to send emissaries to submit tributes to Later Zhou's emperor Guo Rong, but the emissaries were blocked by Later Zhou's vassal Zhou Xingfeng, who then controlled the former Chu lands. In fear, he began to build up his fleet and prepare for defense against an invasion, but not long after began to take up drinking and feasting again, stating, "It would be fortunate for myself to be spared. Why worry about future generations?"

In 958, Liu Sheng died. Liu Jixing (who then changed his name to Liu Chang) succeeded him as emperor.
