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)
Yan Keqiu
In 907, the powerful warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) forced Tang's final emperor Emperor Ai to yield the throne to him, ending Tang and starting a new Later Liang as its Emperor Taizu. Yang Wo, along with several other regional warlords, refused to recognize the Later Liang emperor and continued to use the Tang era name of "Tianyou", but by this point was effectively the ruler of his own domain, then known as Hongnong (as he carried the title of Prince of Hongnong) and later known as Wu (as Yang Xingmi carried the title of Prince of Wu). Nevertheless, by this point, his own powers were limited, as Xu Wen, who was then one of the headquarters guard commanders, as well as fellow guard commander Zhang Hao, had effectively taken over most of Hongnong's governance after killing a number of Yang Wo's associates in a coup earlier in 907. Yan Keqiu's role in the early parts of Yang Wo's administration, if any, is not clear.
