Emperor Ai of Tang
The new Later Liang emperor created Li Chu the Prince of Jiyin and moved him from Luoyang to Cao Prefecture (曹州, in modern Heze, Shandong), and put his mansion under heavy guard, with a fence of thorns surrounding it. In 908, he had Li Chu poisoned to death, and gave Li Chu the posthumous name of "Ai" (哀, "lamentable"). In 928, by which time Li Keyong's adoptive son Li Siyuan was ruling as the emperor of Jin's successor state Later Tang (as Emperor Mingzong), which claimed to be the legitimate continuation of Tang Dynasty and which had earlier destroyed Later Liang, Emperor Mingzong's officials suggested that a temple be built to honor Emperor Ai. Emperor Mingzong had such a temple built at Cao Prefecture. In 929, Emperor Mingzong's officials further suggested giving Emperor Ai a more proper (i.e., more Tang-traditional) posthumous name of Emperor Zhaoxuan Guanglie Xiao, with a temple name of Jingzong, but they also pointed out that since Emperor Ai's temple was not among the imperial ancestral temples, a temple name was not proper. Therefore, only the new posthumous name was adopted, and the temple name was not. Traditional histories thus referred to him mostly as Emperor Ai but also at times as Emperor Zhaoxuan.No family recorded in official histories; Song dynasty general Li Gang was claimed to be a descendant through a son named Li Xizhao (李熙照)

Prince Zhōngwǔ of Fényáng (汾陽忠武王), was the Tang dynasty general who wiped out the An Lushan Rebellion and participated in expeditions against the Uyghur Khaganate and Tibetan Empire. He was regarded as one of the most powerful Tang generals before and after the Anshi Rebellion. After his death he was immortalized in Chinese mythology as the God of Wealth and Happiness (Lu Star of Fu Lu Shou). 
Guo Ziyi was the most successful and satisfactory official in China history. His achievements went far beyond Guo Shu and Guo Ting. He had 8 brothers and 8 sons and 8 son-in-laws. 4 of his sons conferred dukes and 5 of his sons and grandsons became Fuma(damat). all his son-in-laws were top brass of the country. one of his granddaughter became the Empress Dowager Guo (Tang dynasty).
