Overview
Liu Bin (920 – 15 April 943), né Liu Hongdu (劉弘度), possibly nicknamed Shou (壽), also known by his posthumous name as the Emperor Shang of Southern Han (南漢殤帝), was the second emperor of the Chinese Southern Han dynasty. He reigned only briefly, from 942 to 943, from the time of the death of his father Liu Yan (Emperor Gaozu) to the time he was assassinated in a coup headed by his brother Liu Hongxi (later known as Liu Sheng, Emperor Zhongzong).
Background
Liu Hongdu was born in 920, as the third 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). His mother was Liu Yan's concubine Consort Zhao, who would later receive the title of Zhaoyi (昭儀). (The biographies for her and for Liu Hongdu in the Spring and Autumn Annals of the Ten Kingdoms conflictingly state that she was favored by Liu Yan and that she was not favored by Liu Yan.)
The first historical reference to Liu Hongdu was in 932, when Liu Yan created his sons imperial princes—with Liu Hongdu receiving the title of Prince of Bin, which was shortly later changed to Prince of Qin. As his older brothers Liu Yaoshu (劉耀樞) and Liu Guitu (劉龜圖)—both of whom also received princely titles in 932 and therefore were likely still alive then—died early, Liu Hongdu became the expectant heir as the oldest surviving son of Liu Yan. By 934, Liu Hongdu was the commander of the imperial guard corps, when Liu Yan had him recruiting 1,000 guard soldiers to be loyal to him. Liu Hongdu ended up recruiting many young hoodlums and became close to them. The chancellor Yang Dongqian found this inappropriate and tried to persuade Liu Yan to stop this, but Liu Yan paid no heed to Yang's words, leading to Yang's requesting retirement. (As Yang, in his words to Liu Yan, referred to Liu Hongdu as the heir to the state, it was likely that by this point Liu Yaoshu and Liu Guitu were deceased.)
In 942, Liu Yan fell seriously ill. As he had become concerned by this point that both Liu Hongdu and a younger son, Liu Hongxi the Prince of Jin, were arrogant and inappropriate in behavior, he considered sending them out of the capital Xingwang to defend Yong (邕州, in modern Nanning, Guangxi) and Rong (容州, in modern Yulin, Guangxi) Prefectures respectively, while diverting succession to a younger son, Liu Hongchang the Prince of Yue, whom he considered filially pious, careful, and intelligent.
